Description

Frequency scheduling method, device, computer equipment and storage medium

Technical Field

The present application relates to the field of mobile communication technology, and in particular to a frequency scheduling method, device, computer equipment and storage medium.

Background Art

With the official commercial networking of wireless technology (New Radio, NR), neighbor cell measurement is required regardless of whether it is a Long Term Evolution (Long Term Evolution, LTE) system or a NR system.

When implementing neighbor cell measurement in the LTE system, since the terminal has a synchronization signal in each half-frame data received, the terminal can measure the neighbor cell frequency according to a certain period (such as 5ms). In the idle state of the NR system, the neighbor cell measurement is based on the specific location of some periodic synchronization signals (Single Side Band, SSB) provided by the base station. This is because the period, offset and duration of the SSB synchronization signal sent by different base stations can be different, that is, the location of the SSB synchronization signal block is flexible and configurable. In addition, the base station can notify the UE to schedule the neighbor cell frequency according to the SMTC by sending the SSB measurement timing configuration (SSB Measurement Timing Configuration, SMTC) parameter in the System Information Block (SIB) message.

However, as the number of neighboring frequency points increases, there will be a problem of high terminal power consumption when scheduling each neighboring frequency point in the idle state.

Summary of the invention

Based on this, it is necessary to provide a frequency scheduling method, device, computer equipment and storage medium that can reduce the power consumption of the user terminal UE and extend the service life of the UE in order to solve the above technical problems.

The multiple frequency points to be measured are grouped according to their SMTC periods to obtain at least two frequency point sets to be measured; the difference in duration of the SMTC periods of the frequency points to be measured in the frequency point set to be measured is less than a preset threshold;

Determine the module and configure it as follows:

Determine the scheduling position of each of the frequency points to be tested sets according to the SMTC period of the frequency points to be tested in each of the frequency points to be tested sets.

In a third aspect, a computer device comprises a memory and a processor, wherein the memory stores a computer program, and the processor implements the method described in the first aspect when executing the computer program.

In a fourth aspect, a computer-readable storage medium stores a computer program, wherein the computer program, when executed by a processor, implements the method described in the first aspect.

The frequency scheduling method, device, computer equipment and storage medium group multiple frequency points to be tested according to their SMTC periods to obtain a first frequency point set to be tested and a second frequency point set to be tested, and determine the scheduling position of the first frequency point set to be tested in the DRX period according to the SMTC period of each frequency point to be tested in the first frequency point set to be tested, wherein the difference between the duration of the SMTC period of the first frequency point to be tested in the first frequency point set to be tested and the duration of the SMTC period of the second frequency point to be tested in the first frequency point set to be tested is less than the difference between the duration of the SMTC period of the first frequency point to be tested and the duration of the SMTC period of the third frequency point to be tested in the second frequency point set to be tested; the first frequency point to be tested is any frequency point to be tested in the first frequency point set to be tested, the second frequency point to be tested is another frequency point to be tested in the first frequency point set to be tested that is different from the first frequency point to be tested, and the third frequency point to be tested is any frequency point to be tested in the second frequency point set to be tested. In the above method, before determining the scheduling positions of the multiple frequency points to be measured, the UE groups the multiple frequency points to be measured. On the one hand, the SMTC periodic position distribution of the frequency points to be measured contained in the first frequency point set to be measured and the second frequency point set to be measured after grouping is relatively concentrated, which overcomes the problem that the scheduling positions of the determined frequency points to be measured are easily dispersed due to the dispersion of the SMTC periodic positions of the frequency points to be measured in the prior art when determining the scheduling positions of the frequency points to be measured, improves the concentration of the scheduling positions of the frequency points to be measured in each set, achieves the purpose of optimizing the scheduling positions of the frequency points to be measured in each set to be measured, and thus reduces the power consumption of the UE; on the other hand, by grouping and allocating the grouped frequency point sets to be measured to different DRX cycles for scheduling, it is achieved that the frequency points to be measured that are originally required to be scheduled in one or some DRX cycles are shifted to other DRX cycles for centralized scheduling, so that one or some DRX cycles are idle, that is, no frequency points to be measured need to be scheduled in the DRX cycle in the future, thereby reducing the power consumption of the UE and delaying the operation of the UE. The service life of UE is prolonged and the user experience of UE is improved.

A specific application system may include more or fewer components than those shown in the figure, or combine certain components, or have a different arrangement of components.

In the idle state of the existing NR system, when all the test frequencies are scheduled in different discontinuous reception cycles (DRX), usually a single test frequency is allocated to each discontinuous reception cycle for scheduling. For example, as shown in FIG1A, the test frequencies are F1, F2 and F3. When scheduling these three test frequencies, F1, F2 and F3 can be allocated to different discontinuous reception cycles DRX cycle n, DRX cycle n+1 and DRX cycle n+2 for scheduling. The test frequencies in FIG1A are scheduled in the measurement gap gap2 in their respective discontinuous cycles. This is only an example. In actual applications, the test frequencies in FIG1A can also be scheduled in the measurement gap gap1 in their respective discontinuous cycles, which is not limited here.

Although the above existing scheduling method for scheduling a single frequency to be measured in different discontinuous reception cycles DRX cycle is simple to implement, since all the frequencies to be measured are scattered in different discontinuous reception cycles, it means that the UE is performing frequency scheduling in each discontinuous reception cycle, which will lead to the problem of increased UE power consumption. In order to solve this problem, the present application proposes a frequency scheduling method, which optimizes the scheduling positions of the frequencies to be measured in different discontinuous reception cycles, and specifically concentrates the scattered different frequencies to be measured in one discontinuous reception cycle or a small number of discontinuous reception cycles for scheduling, so that the UE can not perform frequency scheduling in one or some discontinuous reception cycles, thereby achieving the purpose of reducing UE power consumption and extending UE service life. The following embodiments will specifically illustrate the frequency scheduling method described in the present application.

In one embodiment, as shown in FIG2 , a frequency scheduling method is provided, which schedules multiple frequency points to be measured. The method is applied to the user terminal UE in FIG1 as an example for description, and includes the following steps:

S101, grouping multiple frequency points to be measured according to their SMTC periods to obtain a first set of frequency points to be measured and a second set of frequency points to be measured.

The difference between the duration of the SMTC period of the first frequency point to be measured in the first set of frequency points to be measured and the duration of the SMTC period of the second frequency point to be measured in the first set of frequency points to be measured is less than the difference between the duration of the SMTC period of the first frequency point to be measured and the duration of the SMTC period of the third frequency point to be measured in the second set of frequency points to be measured; wherein the first frequency point to be measured is any frequency point to be measured in the first set of frequency points to be measured, the second frequency point to be measured is another frequency point to be measured in the first set of frequency points to be measured that is different from the first frequency point to be measured, and the third frequency point to be measured is any frequency point to be measured in the second set of frequency points to be measured. Optionally, the difference between the duration of the SMTC periods of the various frequency points to be measured in the first set of frequency points to be measured is less than a preset threshold, and the difference between the duration of the SMTC periods of the various frequency points to be measured in the second set of frequency points to be measured is also less than the preset threshold.

In this embodiment, the UE can determine all the test frequency points that need to be scheduled based on the system information block SIB received from the base station or the network side. Specifically, as shown in Figure 2A, the base station or the network side (NW) can send SIB2 information and SIB4 information to the UE. When the UE receives the SIB2 information, it can extract the SMTC related parameters of the same-frequency test frequency points, and when the UE receives the SIB2 information, it can extract the SMTC related parameters of the different-frequency test frequency points. In this way, multiple test frequency points can be determined, and the determined multiple test frequency points can be used as all the test frequency points that need to be scheduled.

When the UE determines multiple frequency points to be measured, since the multiple frequency points to be measured can be allocated for scheduling in different discontinuous reception periods, and in order to reasonably allocate them, it is necessary to first determine the frequency points to be measured that need to be scheduled in each discontinuous reception period. In this embodiment, in the process of determining each test frequency point that needs to be scheduled in each discontinuous reception period, the UE may first group all the test frequency points to obtain a first test frequency point set and a second test frequency point set, and make the difference between the duration of the SMTC period of the first test frequency point in the first test frequency point set after grouping and the duration of the SMTC period of the second test frequency point in the first test frequency point set less than the difference between the duration of the SMTC period of the first test frequency point and the duration of the SMTC period of the third test frequency point in the second test frequency point set; optionally, the difference between the duration of the SMTC period of each test frequency point in each test frequency point set contained in the first test frequency point set and the second test frequency point set after grouping may also be made less than a preset threshold, that is, the difference between the duration of the SMTC period of each test frequency point contained in the first test frequency point set and the second test frequency point set is made very small, so as to better concentrate the scheduling positions of each test frequency point in each test frequency point set.

The above grouping method is exemplified. When the UE groups multiple frequency points to be measured, the frequency points to be measured with shorter SMTC periods can be grouped into a group according to the SMTC periods of each frequency point to be measured to obtain a first set of frequency points to be measured, and the frequency points to be measured with longer SMTC periods can be grouped into a group to obtain a second set of frequency points to be measured, so that the difference in the duration of the SMTC period between any frequency point to be measured in the first set of frequency points to be measured and other frequency points to be measured in the set is smaller than the difference in the duration of the SMTC period between the frequency point to be measured and any frequency point to be measured in the second set of frequency points to be measured. For example, the frequencies to be measured include F1, F2, F3, F4, and F5, and the SMTC periods of these five frequencies to be measured are 5ms, 10ms, 20ms, 80ms, and 160ms, respectively. After the five frequencies to be measured are grouped according to the first method, a first set of frequencies to be measured can be obtained as [5ms, 10ms, 20ms], and a second set of frequencies to be measured can be obtained as [80ms, 160ms]. The difference in duration of the SMTC period between any frequency to be measured in the first set of frequencies to be measured and the other frequency to be measured is any one of 5ms, 10ms, and 15ms. The difference in duration of the SMTC period between any frequency to be measured in the first set of frequencies to be measured and any frequency to be measured in the second set of frequencies to be measured is any one of 75ms, 155ms, 70ms, 150ms, 60ms, and 140ms. The difference in duration of the SMTC period between any frequency to be measured in the first set of frequencies to be measured and the other frequency to be measured is any one of 80ms, 160ms, 10ms, 20ms, 80ms, and 160ms. The difference in the duration of the SMTC period between any frequency to be tested in the first set of frequency points to be tested and any frequency to be tested in the second set of frequency points to be tested is smaller than the difference in the duration of the SMTC period between any frequency to be tested in the first set of frequency points to be tested and any frequency to be tested in the second set of frequency points to be tested. Obviously, after grouping according to the above method, the duration of the SMTC period between the first set of frequency points to be tested and the second set of frequency points to be tested obtained after grouping is far apart, so the first set of frequency points to be tested and the second set of frequency points to be tested can be allocated to different DRX cycles for scheduling in the later stage. Compared with allocating the two sets of frequency points to be tested to one DRX cycle for scheduling, the wake-up duration of the scheduled frequency points to be tested in the same DRX cycle and the number of sleep to wake-up can be reduced, thereby improving scheduling efficiency and reducing UE power consumption. It should be noted that the duration of the SMTC period between the first set of frequency points to be tested and the second set of frequency points to be tested refers to the difference in the duration of the SMTC period between any frequency to be tested in the first set of frequency points to be tested and any frequency to be tested in the second set of frequency points to be tested. In addition, the SMTC periods of the various frequencies to be tested in the various frequency points to be tested sets after grouping are relatively similar. When the various frequencies to be tested in each frequency point to be tested set are scheduled later, the UE can centrally schedule all the frequencies to be tested in each frequency point to be tested set. It should be noted that the preset threshold can be determined in advance by the UE according to the grouping requirements. The above example divides the frequencies to be tested into two groups, which is only an example. The number of groups is determined according to the actual application situation and is not limited here.

S102: Determine a scheduling position of the first set of frequency points to be measured within a DRX cycle according to the SMTC period of each frequency point to be measured in the first set of frequency points to be measured.

The DRX cycle is called a discontinuous reception cycle, and the scheduling position of the first set of test frequency points in the DRX cycle specifically refers to the scheduling position of each test frequency point in the first set of test frequency points in the corresponding DRX cycle. In this embodiment, after the UE groups multiple test frequency points based on the method described in the above steps, the first set of test frequency points and the second set of test frequency points are obtained, and then the two sets of test frequency points can be allocated to different DRX cycles for scheduling. Specifically, the two sets of test frequency points can be allocated to two DRX cycles for scheduling; after the UE determines the set of test frequency points to be scheduled in each DRX cycle, the scheduling position of each test frequency point in the first set of test frequency points in the DRX cycle corresponding to the set can be further determined according to the SMTC cycle of the test frequency points in the first set of test frequency points, and the scheduling position of each test frequency point in the second set of test frequency points in the DRX cycle corresponding to the set can be determined according to the SMTC cycle of the test frequency points in the second set of test frequency points. Specifically, when determining the scheduling position of each frequency point to be measured in each frequency point to be measured set, the scheduling can be performed according to the order of the SMTC cycle of each frequency point to be measured from small to large. For example, as shown in FIG2B , a DRX cycle n is taken as an example for explanation. In the DRX cycle n, the first frequency point to be measured set needs to be scheduled, and the first frequency point to be measured set includes: F1, F2, F3, F4 and F5. The SMTC cycles of these five frequency points to be measured are 5ms, 10ms, 20ms, 80ms and 160ms respectively. When determining the scheduling position of all the frequency points to be measured in the measurement gap 2, the five frequency points to be measured can be firstly sorted in the order of the SMTC cycle from small to large, and then the scheduling of each frequency point to be measured can be performed in the measurement gap 2 according to the order. See FIG2B for the arrangement of the scheduling positions of each frequency point to be measured in order. Optionally, the UE can also determine the scheduling position of each frequency point to be measured in each frequency point to be measured set in other ways.

It should be noted that, when different test frequencies were originally scheduled in different DRX cycles, different test frequencies were allocated to corresponding different DRX cycles for scheduling (for example, the scheduling method shown in FIG1 ), so there is a test frequency that needs to be scheduled in each DRX cycle. In this embodiment, after all the test frequencies are grouped, different test frequency sets are allocated to different discontinuous reception cycles for scheduling, and some test frequency sets may include test frequencies in multiple DRX cycles, which is equivalent to moving the test frequencies in other DRX cycles to another discontinuous reception cycle for scheduling. This can make some of the original DRX cycles that need to schedule the test frequencies idle. For example, as shown in FIG2C , the original test frequencies F1, F2, and F3 are allocated to different discontinuous reception cycles DRXcycle n, DRX cycle n+1, and DRX cycle n+2 for scheduling (refer to the method shown in FIG1A ). The scheduling method is as follows: however, after the tested frequency points F1, F2 and F3 are grouped, a first tested frequency point set and a second tested frequency point set are obtained, and the first tested frequency point set includes the tested frequency points F1 and F2, and the second tested frequency point set includes the tested frequency point F3. Different tested frequency point sets are allocated to different DRX cycles for scheduling, that is, the first tested frequency point set is allocated to the DRX cycle for scheduling, and the second tested frequency point set is allocated to the DRX cycle n+2 for scheduling. Since the tested frequency point F2 that needs to be scheduled in the original DRXcycle n+1 cycle is moved to the DRX cycle for scheduling, the original DRX cycle n+1 is idle, that is, there is no need to schedule any tested frequency point in the DRX cycle n+1 in the later stage.

The frequency scheduling method provided in the above embodiment groups multiple frequency points to be tested according to their SMTC periods to obtain a first frequency point set to be tested and a second frequency point set to be tested, and determines the scheduling position of the first frequency point set to be tested in the DRX period according to the SMTC period of each frequency point to be tested in the first frequency point set to be tested, wherein the difference between the duration of the SMTC period of the first frequency point to be tested in the first frequency point set to be tested and the duration of the SMTC period of the second frequency point to be tested in the first frequency point set to be tested is less than the difference between the duration of the SMTC period of the first frequency point to be tested and the duration of the SMTC period of the third frequency point to be tested in the second frequency point set to be tested; the first frequency point to be tested is any frequency point to be tested in the first frequency point set to be tested, the second frequency point to be tested is another frequency point to be tested in the first frequency point set to be tested that is different from the first frequency point to be tested, and the third frequency point to be tested is any frequency point to be tested in the second frequency point set to be tested. In the above method, before determining the scheduling positions of the multiple frequency points to be measured, the UE groups the multiple frequency points to be measured. On the one hand, the SMTC periodic position distribution of the frequency points to be measured contained in the first frequency point set to be measured and the second frequency point set to be measured after grouping is relatively concentrated, which overcomes the problem that the scheduling positions of the determined frequency points to be measured are easily dispersed due to the dispersion of the SMTC periodic positions of the frequency points to be measured in the prior art when determining the scheduling positions of the frequency points to be measured, improves the concentration of the scheduling positions of the frequency points to be measured in each set, achieves the purpose of optimizing the scheduling positions of the frequency points to be measured in each set of frequency points to be measured, and thus reduces the power consumption of the UE; on the other hand, by grouping and allocating the grouped frequency point sets to be measured to different DRX cycles for scheduling, it is achieved that the frequency points to be measured that are originally required to be scheduled in one or some DRX cycles are shifted to other DRX cycles for centralized scheduling, so that one or some DRX cycles are idle, that is, they are not required to be scheduled in the DRX cycle in the later stage. Any frequency point to be measured is scheduled within the period, thereby reducing the power consumption of the UE, extending the service life of the UE, and improving the user experience of using the UE.

In one embodiment, an implementation of the above S102 is provided, as shown in FIG3, wherein the above S102 "determining the scheduling position of the first set of frequency points to be tested in the DRX cycle according to the SMTC cycle of each frequency point to be tested in the first set of frequency points to be tested" includes:

S201, determine a DRX cycle corresponding to the first set of frequency points to be measured according to the SMTC cycle of each frequency point to be measured in the first set of frequency points to be measured.

In this embodiment, when the UE groups multiple frequency points to be measured to obtain a first set of frequency points to be measured and a second set of frequency points to be measured, the two sets of frequency points to be measured may be allocated to different DRX cycles for scheduling; optionally, the UE may also allocate the two sets of frequency points to be measured to one DRX cycle for scheduling. When the UE needs to allocate the two sets of frequency points to be measured to different DRX cycles for scheduling, it is necessary to first determine the discontinuous reception cycle corresponding to each set of frequency points to be measured, that is, determine in which discontinuous reception cycle the frequency points to be measured in the first set of frequency points to be measured need to be scheduled, and determine in which discontinuous reception cycle the frequency points to be measured in the second set of frequency points to be measured need to be scheduled. When specifically determining, it may be determined according to the SMTC cycle of the frequency points to be measured in the first set of frequency points to be measured, and according to the SMTC cycle of the frequency points to be measured in the second set of frequency points to be measured. For example, the UE may directly sort the two frequency point sets to be tested according to the SMTC periods of the frequency points to be tested contained in each of the two frequency point sets to be tested, and specifically allocate the SMTC periods in ascending order to different discontinuous reception periods arranged in sequence, referring to FIG3A , wherein the first frequency point set to be tested includes frequency points F1, F2, and F3 to be tested; the second frequency point set to be tested includes frequency points F4 and F5 to be tested, and the difference between the duration of the SMTC period of any frequency point to be tested in the first frequency point set to be tested and the duration of the SMTC period of other frequency points to be tested in the set is smaller than the difference between the duration of the SMTC period of any frequency point to be tested in the first frequency point set to be tested and the duration of the SMTC period of any frequency point to be tested in the second frequency point set to be tested, for example, the difference between the duration of the SMTC periods of the frequency points F1 and F2 to be tested in the first frequency point set to be tested is smaller than the difference between the duration of the SMTC period of the frequency point F1 to be tested in the first frequency point set to be tested and the duration of the SMTC period of the frequency point F4 to be tested in the second frequency point set to be tested. The test frequency points F1, F2 and F3 in the first test frequency point set are allocated to the first DRX cycle (DRX cycle n) for scheduling, that is, the first test frequency point set is determined to correspond to the DRX cycle DRX cycle n; F4 and F5 in the second test frequency point set are allocated to the second DRX cycle (DRX cycle n+1) for scheduling, that is, the test frequency point set #2 is determined to correspond to the discontinuous reception cycle DRX cyclen+1.

Optionally, a method for determining a test frequency point that needs to be scheduled in a discontinuous reception period is provided, that is, a method for determining a test frequency point that needs to be scheduled in a non-DRX period corresponding to a first test frequency point set, as shown in FIG3B, the method comprising:

S2011, obtaining the time difference between the SMTC periods of each frequency point to be measured.

When the UE determines the SMTC period of each frequency point to be measured, it can further calculate the time difference between the SMTC periods of each frequency point to be measured to determine the length of the interval between the SMTC periods of each frequency point to be measured, and then determine the frequency points to be measured that need to be scheduled in different discontinuous reception periods based on the length of the time.

S2012, determine the test frequency points whose time difference is less than a preset threshold as all the test frequency points that need to be scheduled within one DRX cycle.

The preset threshold is used to measure the length of the interval between the SMTC cycles of each frequency point to be measured. If the interval between the SMTC cycles of each frequency point to be measured is greater than the preset threshold, it means that the interval between the SMTC cycles of each frequency point to be measured is longer. If the interval between the SMTC cycles of each frequency point to be measured is not greater than the preset threshold, it means that the interval between the SMTC cycles of each frequency point to be measured is short. The preset threshold can be determined by the UE in advance according to scheduling requirements.

In this embodiment, when the UE calculates the time difference between the SMTC cycles of each frequency point to be measured, it can further compare the time difference with a preset threshold, and move the frequency points to be measured whose time difference is less than the preset threshold into a DRX cycle, and determine them together with the original frequency points to be measured in the DRX cycle as all the frequency points to be measured that need to be scheduled in the DRX cycle.

The method described in the embodiment of Figure 3C is exemplified. As shown in Figure 3C, the frequency points to be measured in all DRX cycles include F1, F2 and F3, and the SMTC periods are 5ms, 10ms and 80ms respectively. The existing scheduling method is as shown in Figure 1A, scheduling the frequency point F1 to be measured in the DRX cyclen period, scheduling the frequency point F2 to be measured in the DRX cycle n+1 period, and scheduling the frequency point F3 to be measured in the DRX cycle n+2 period. Use the method described in the embodiment of Figure 3B to re-determine all the test frequencies in a DRX cycle (for example, DRXcycle n in the figure). The time difference between the duration of the SMTC cycles of the test frequencies F1 and F2 is 5ms, and the time difference between the duration of the SMTC cycles of the test frequencies F1 and F3 is 75ms. 5ms is less than 75ms, so the test frequency F2 originally scheduled in DRX cyclen+1 is moved to DRX cycle n for scheduling. Referring to the schematic diagram shown in Figure 3C, the test frequencies F1 and F2 are scheduled in the corresponding DRX cycle n, and no frequency scheduling is performed in the corresponding DRX cycle n+1, thereby reducing UE power consumption. It should be noted that after using the above method to move the frequency points to be measured in other DRX cycles to one DRX cycle for scheduling, since the frequency points to be measured in other DRX cycles are all one frequency point to be measured (see the frequency point F3 to be measured in DRX cycle n+2 in Figure 3C), the current SMTC cycle position of the frequency point to be measured in other DRX cycles can be directly determined as the scheduling position of the frequency point to be measured, and the current SMTC cycle position of the frequency point to be measured in other DRX cycles is the SMTC cycle position of the frequency point to be measured that coincides with the paging moment, or, the current SMTC cycle position of the frequency point to be measured in other DRX cycles is the first SMTC cycle position of the frequency point to be measured after the paging moment. The above-mentioned one DRX cycle can be any DRX cycle among all DRX cycles, that is, DRX cycle n, DRX cycle n+1, and DRX cycle n+2 in FIG. 3C can all be used as a DRX cycle. When determining the frequency points to be measured in each DRX cycle, the frequency point to be measured F2 in DRX cycle n+1 can be moved to DRX cycle n, and of course, the frequency point to be measured F1 in DRX cycle n can also be moved to DRX cycle n+1. When other frequency points to be measured are moved to a non-DRX cycle, all the frequency points to be measured contained in the DRX cycle also constitute a set of frequency points to be measured.

S202: Determine a scheduling position of each frequency point to be measured in the first set of frequency points to be measured in a corresponding DRX cycle according to the SMTC cycle of each frequency point to be measured in the first set of frequency points to be measured.

When the UE determines the discontinuous reception period corresponding to the first set of test frequencies, the scheduling position of each test frequency in the first set of test frequencies can be further determined. When specifically determined, it can be determined according to the SMTC period of the test frequency in the first set of test frequencies. For example, it can be scheduled according to the SMTC period of each test frequency in the first set of test frequencies in a small to large order. As shown in FIG2B , a DRX cycle n is taken as an example for explanation. The test frequencies to be scheduled in the DRX cycle n include: F1, F2, F3, F4 and F5. The SMTC periods of the five test frequencies are 5ms, 10ms, 20ms, 80ms and 160ms respectively. When determining the scheduling position of all the test frequencies in the measurement gap 2, the five test frequencies can be firstly sorted in a small to large order according to the SMTC period, and then the scheduling of each test frequency in the measurement gap 2 is performed according to the order. See FIG2B for the arrangement of the scheduling positions of the test frequencies in a sequence. Optionally, the UE may also first group the test frequencies included in the first test frequency set according to the grouping method described in S101 to obtain multiple test frequency groups, and then determine the scheduling position of each test frequency group and schedule each test frequency according to the determined scheduling position. It should be noted that this embodiment describes a method for determining the scheduling position of each test frequency in the first test frequency set in the corresponding DRX cycle, and the method for determining the scheduling position of each test frequency in the second test frequency set in the corresponding DRX cycle is consistent with the above method for determining the scheduling position of each test frequency in the first test frequency set, and is not described in detail here.

Furthermore, a method for the UE to determine the scheduling position of each frequency point to be measured in the first set of frequency points to be measured in the corresponding DRX cycle is provided. As shown in FIG4 , the method includes:

S301, in the DRX cycle corresponding to the first set of frequencies to be measured, determining the SMTC periodic positions of the third frequency point to be measured and the fourth frequency point to be measured.

Among them, the third frequency point to be measured is the frequency point to be measured with the smallest SMTC period in the first frequency point set to be measured, and the fourth frequency point to be measured is other frequency points to be measured in the first frequency point set to be measured. Optionally, the fourth frequency point to be measured can be any frequency point to be measured among the other frequency points to be measured in the first frequency point set to be measured, for example, the fourth frequency point to be measured can be the frequency point to be measured with the smallest SMTC period among the other frequency points to be measured, or can be the frequency point to be measured with the largest SMTC period among the other frequency points to be measured.

In this embodiment, when the UE groups multiple frequency points to be measured to obtain a first set of frequency points to be measured, it can first determine the third frequency point to be measured and the fourth frequency point to be measured in the first set of frequency points to be measured according to the SMTC period of each frequency point to be measured in the first set of frequency points to be measured, and then further determine the SMTC periodic position of the third frequency point to be measured and the SMTC periodic position of the fourth frequency point to be measured.

S302. When the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, the SMTC periodic position after the current SMTC periodic position of the third frequency point to be measured is determined as the scheduling position of the third frequency point to be measured.

In the DRX cycle corresponding to the first set of frequencies to be measured, the UE usually schedules all the frequencies to be measured in the first set of frequencies to be measured in a measurement gap in the DRX cycle. For example, as shown in FIG. 4A, a schematic diagram of a measurement gap in an idle state, in which DRX cycle n is the DRX cycle corresponding to the set of frequencies to be measured, P0 is the paging time in the DRX cycle, there is a measurement gap gap1 before P0, and there is a measurement gap gap2 after P0. In actual applications, the UE may schedule all the frequencies to be measured in gap1 or in gap2. In this embodiment, the UE may schedule the third and fourth frequencies to be measured in gap1 or in gap2, wherein the third and fourth frequencies to be measured may be frequencies to be measured of the same frequency or frequencies to be measured of different frequencies. The SMTC period of the third and fourth frequencies to be measured may be the same or different.

The current SMTC periodic position of the third frequency to be measured is the SMTC periodic position of the third frequency to be measured that coincides with the paging time, or the current SMTC periodic position of the third frequency to be measured is the first SMTC periodic position of the third frequency to be measured after the paging time. Optionally, the current SMTC periodic position of the third frequency to be measured can be determined by the frame number or subframe number of the SMTC period of the third frequency to be measured, and the definition of the frame number or subframe number is described in 3GPP 38.331, for example, see the following description:

According to 3GPP 38.331

Section 5.5.2.10 Reference signal measurement timing configuration The specific method is as follows:

The UE shall setup the first SS/PBCH block measurement timingconfiguration (SMTC)in accordance with the received periodicityAndOffsetparameter(providing Periodicity and Offset value for the following condition)in the smtc1 configuration. The first subframe of each SMTC occasion occurs at an SFN and subframe of the NR SpCell meets the following condition:

SFN mod T＝(FLOOR(Offset/10));

if the Periodicity is larger than sf5:

subframe = Offset mod 10;

else:

subframe=Offset or(Offset+5);

with T＝CEIL(Periodicity/10).

Wherein, subframe represents a frame number or a subframe number.

In this embodiment, the UE may first determine the current SMTC periodic position of the third frequency to be measured and the next SMTC periodic position of the third frequency to be measured according to the paging time. In this embodiment, the measurement gap after the paging time is taken as an example for illustration. The UE may determine the SMTC periodic position of the third frequency to be measured that coincides with the paging time as the current SMTC periodic position of the third frequency to be measured, and determine the next SMTC periodic position of the third frequency to be measured relative to the current SMTC periodic position of the third frequency to be measured, for example, as shown in FIG4B , smtc n is the current SMTC periodic position of the third frequency to be measured, and smtc n+1 is the next SMTC periodic position of the third frequency to be measured.

When the UE specifically schedules the third frequency point to be measured and the fourth frequency point to be measured, the UE can first determine whether the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, and if included, directly determine the SMTC periodic position after the current SMTC periodic position of the third frequency point to be measured as the scheduling position of the third frequency point to be measured. Specifically, any SMTC periodic position after the current SMTC periodic position of the third frequency point to be measured can be determined as the scheduling position of the third frequency point to be measured. For example, as shown in Figure 4B, F1 is the third frequency point to be measured, F2 is the fourth frequency point to be measured, smtc n is the current SMTC periodic position of F1, and smtc n+1 is the next SMTC periodic position of F1. If the SMTC periodic position of the fourth frequency point to be measured is included between smtc n and smtc n+1 (a in the figure), then any SMTC periodic position after smtc n of F1 can be further determined as the scheduling position of F1 (any SMTC periodic position in the dotted box in the figure).

Optionally, the UE may determine the current SMTC periodic position of the fourth frequency point to be measured as the scheduling position of the fourth frequency point to be measured when the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, and the SMTC period of the third frequency point to be measured is different from the SMTC period of the fourth frequency point to be measured.

The frequency scheduling method provided in the above embodiment implements the scheduling of the third frequency to be measured by determining the SMTC periodic position after the current SMTC periodic position of the third frequency to be measured as the scheduling position of the third frequency to be measured when the SMTC periodic position of the fourth frequency to be measured is included between the current SMTC periodic position of the third frequency to be measured and the next SMTC periodic position of the third frequency to be measured. In which, since the scheduling position of the third frequency to be measured is after the current SMTC periodic position of the third frequency to be measured, that is, the scheduling position of the third frequency to be measured is delayed, the above frequency scheduling method can implement the UE to extend a certain time for scheduling when scheduling each frequency to be measured, so that the UE can enter a sleep state for a longer period of time within a DRX cycle, or reduce the frequency of the UE's wake-up and sleep conversion within a DRX cycle, thereby reducing the power consumption of the UE, extending the service life of the UE, and improving the user experience of using the UE.

Optionally, when the UE specifically determines to determine the SMTC periodic position after the current SMTC periodic position of the third frequency to be measured as the scheduling position of the third frequency to be measured, the first SMTC periodic position after the current SMTC periodic position of the third frequency to be measured can be specifically determined as the scheduling position of the third frequency to be measured. For example, as shown in Figure 4B, F1 is the third frequency to be measured, F2 is the fourth frequency to be measured, smtc n is the current SMTC periodic position of F1, and smtc n+1 is the next SMTC periodic position of F1. If the SMTC periodic position of the fourth frequency to be measured is included between smtc n and smtc n+1 (a in the figure), the first SMTC periodic position after smtc n of F1 can be further determined as the scheduling position of F1 (the SMTC periodic position pointed to by b in the dotted box in the figure). By determining the first SMTC periodic position as the scheduling position of the third frequency point to be measured, the scheduling positions of the third and fourth frequency points to be measured can be concentrated. For example, as shown in the figure of FIG4B, if the current SMTC periodic position of the fourth frequency point to be measured (F2) is determined as the scheduling position of the fourth frequency point to be measured (the SMTC periodic position pointed to by a in the figure), and the first SMTC periodic position after the current SMTC periodicity of the third frequency point to be measured (F1) is determined as the scheduling position of the third frequency point to be measured, then the scheduling position of F1 and the scheduling position of F2 are relatively concentrated (such as the positions a and b in the figure), which overcomes the problem that when the prior art determines the scheduling position of each frequency point to be measured, the scheduling position of each frequency point to be measured is easily dispersed due to the dispersion of the SMTC periodic positions of each frequency point to be measured. The concentration of the scheduling positions of the frequency points to be measured is improved, and the purpose of optimizing the scheduling positions of the frequency points to be measured is achieved, thereby reducing the power consumption of the UE.

In actual applications, the UE may also schedule the third frequency point to be measured, the fourth frequency point to be measured and the fifth frequency point to be measured in the DRX cycle corresponding to the first frequency point to be measured set. Following the above-mentioned method S302, the UE may first determine whether the SMTC periodic position of the fourth frequency point to be measured and the SMTC periodic position of the fifth frequency point to be measured are included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, and in the case where the SMTC periodic position of the fourth frequency point to be measured and the SMTC periodic position of the fifth frequency point to be measured are included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, since two frequency points to be measured are included, the SMTC periodic position of the fourth frequency point to be measured and the SMTC periodic position of the fifth frequency point to be measured may overlap or may not overlap. Based on these two situations, the scheduling methods of each frequency point to be measured are also different. The following describes these two different scheduling methods respectively:

First, if the SMTC periodic position of the fourth frequency point to be measured does not overlap with the SMTC periodic position of the fifth frequency point to be measured, it means that the SMTC periodicity of the fourth frequency point to be measured is different from the SMTC periodicity of the fifth frequency point to be measured. Based on this, the UE determines the current SMTC periodic position of the fourth frequency point to be measured as the scheduling position of the fourth frequency point to be measured, and determines the current SMTC periodic position of the fifth frequency point to be measured as the scheduling position of the fifth frequency point to be measured. For example, as shown in FIG5, F1 is the third frequency point to be measured, F2 is the fourth frequency point to be measured, and F3 is the fifth frequency point to be measured. The SMTC periodic position of F2 and the SMTC periodic position of F3 are included between the current SMTC periodic position of F1 and the next SMTC periodic position, and the included SMTC periodic position of F2 and the SMTC periodic position of F3 do not overlap (see the SMTC periodic positions of F2 and F3 in the virtual box). Then, the current SMTC periodic position of F2 (the position indicated by b in the figure) is set. The scheduling position of F2 is determined as the scheduling position of F2, and the current SMTC periodic position of F3 (the position indicated by c in the figure) is determined as the scheduling position of F3. The scheduling position of F1 can be determined according to the above method, that is, the first SMTC periodic position after the current SMTC periodic position of F1 is determined as the scheduling position of F1. The position indicated by a in Figure 5 is the scheduling position of F1.

Second, if the SMTC periodic position of the fourth frequency point to be measured coincides with the SMTC periodic position of the fifth frequency point to be measured, it means that the SMTC periodicity of the fifth frequency point to be measured is the same as the SMTC periodicity of the fifth frequency point to be measured. Based on this, the UE determines the current SMTC periodic position of the fourth frequency point to be measured as the scheduling position of the fourth frequency point to be measured, and determines the first SMTC periodic position after the current SMTC periodic position of the fifth frequency point to be measured as the scheduling position of the fifth frequency point to be measured. For example, as shown in FIG6, F1 is the third frequency point to be measured, F2 is the fourth frequency point to be measured, and F3 is the fifth frequency point to be measured. The SMTC periodic position of F2 and the SMTC periodic position of F3 are included between the current SMTC periodic position of F1 and the next SMTC periodic position, and the SMTC periodic position of F2 coincides with the SMTC periodic position of F3 (see the SMTC periodic positions of F2 and F3 in the virtual box). Then the current SMTC periodic position of F2 is determined as the scheduling position of the fifth frequency point to be measured. The first SMTC periodic position after the current SMTC periodic position of F3 (the position indicated by e in the figure) is determined as the scheduling position of F2, and the first SMTC periodic position after the current SMTC periodic position of F3 (the position indicated by e in the figure) is determined as the scheduling position of F3. The scheduling position of F1 can be determined according to the above method, that is, the first SMTC periodic position after the current SMTC periodic position of F1 is determined as the scheduling position of F1, and the position indicated by a in Figure 6 is the scheduling position of F1.

The above embodiment provides a scheduling method for the frequency points to be measured that overlap the periodic positions of the SMTC, so that when the UE is scheduled according to the scheduling positions of the frequency points to be measured, conflict scheduling of the overlapping frequency points to be measured can be avoided. At the same time, the overlapping frequency points to be measured can be centrally scheduled, thereby achieving the purpose of reducing UE power consumption.

The above embodiments are all based on the scheduling method of each frequency point to be measured when the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured. In actual applications, the SMTC periodic position of the fourth frequency point to be measured may not be included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured. In this case, the next SMTC periodic position of the third frequency point to be measured is updated to the current SMTC periodic position, and the step of returning to execute is to determine the SMTC periodic position after the current SMTC periodic position of the third frequency point to be measured as the scheduling position of the third frequency point to be measured when the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured.

In this embodiment, when the SMTC periodic position of the fourth frequency point to be measured is not included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, the current SMTC periodic position of the third frequency point to be measured is slid, specifically, the current SMTC periodic position of the third frequency point to be measured is slid to the next SMTC periodic position, and the next SMTC periodic position of the third frequency point to be measured is slid to the next SMTC periodic position of the next SMTC periodic position of the third frequency point to be measured. For example, as shown in FIG7 , F1 is the third frequency point to be measured, and F2 is the fourth frequency point to be measured. The SMTC periodic position of F2 is not included between the current SMTC periodic position of F1 and the next SMTC periodic position. Then, the next SMTC periodic position of F1 (the position indicated by B in the figure) is updated to the current SMTC periodic position of F1 (the original current SMTC periodic position of F1 is the position indicated by A), and the next SMTC periodic position of the next SMTC periodic position of F1 is updated to the next SMTC periodic position of F1. The next SMTC periodic position of F1 (the position indicated by C in the figure) is updated to the next SMTC periodic position of F1 (the original next SMTC periodic position of F1 is the position indicated by B).

After the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured are updated, the UE can re-determine whether the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, and if included, determine the scheduling position of each frequency point to be measured for frequency scheduling based on the method described in S302. This method determines the scheduling position of each frequency point to be measured only when the SMTC periodic position of the fourth frequency point to be measured is included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, and does not determine the scheduling position of each frequency point to be measured when the SMTC periodic position of the fourth frequency point to be measured is not included between the current SMTC periodic position of the third frequency point to be measured and the next SMTC periodic position of the third frequency point to be measured, which can improve the concentration of the scheduling positions of each frequency point to be measured, realize centralized scheduling within a DRX cycle, and thus reduce UE power consumption.

In actual applications, when the UE groups multiple frequency points to be measured to obtain a first set of frequency points to be measured and a second set of frequency points to be measured, some of the first set of frequency points to be measured or the second set of frequency points to be measured may contain multiple frequency points to be measured or only one frequency point to be measured. When multiple frequency points to be measured are included, all the frequency points to be measured included in the first set of frequency points to be measured or the second set of frequency points to be measured may be grouped to determine the scheduling positions of the frequency points to be measured in each group in a set of frequency points to be measured, so that the time interval between the scheduling positions of each group is greater than the preset time interval, so as to lengthen the time length between the scheduling positions of each group. Based on this, the present application also provides a scheduling method, as shown in FIG8, the method includes:

S401, grouping multiple frequency points to be measured in the first frequency point set to be measured according to the SMTC period of each frequency point to be measured in the first frequency point set to obtain at least two frequency point subsets to be measured.

Among them, the difference between the duration of the SMTC period of any frequency point to be measured in the frequency point subset to be measured and the duration of the SMTC period of other frequency points to be measured is less than the first preset threshold. The difference between the duration of the SMTC period of any frequency point to be measured in the frequency point subset to be measured and the duration of the SMTC period of any frequency point to be measured in the other frequency point subsets to be measured is greater than the second preset threshold. The first preset threshold is used to evaluate whether the duration between the SMTC periods of each frequency point to be measured in a frequency point subset is small, and the second preset threshold is used to evaluate whether the duration between the SMTC periods of each frequency point to be measured in different frequency point subsets is long. The first preset threshold and the second preset threshold can be predetermined by grouping requirements.

The present embodiment relates to a method for grouping each frequency point to be tested in a set of frequency points to be tested, thereby obtaining a plurality of frequency point subsets to be tested, so as to schedule each frequency point to be tested in each frequency point subset to be tested later. The specific grouping method involved in this embodiment can refer to the grouping method described in S101 in the embodiment of FIG. 2 above, and will not be repeated here. It should be noted that, in this embodiment, after the first set of frequency points to be tested is grouped, the difference between the duration of the SMTC period of any frequency point to be tested in the frequency point subset to be tested and the duration of the SMTC period of other frequency points to be tested is less than a preset threshold, indicating that the SMTC periods of the frequency points to be tested in the grouped frequency point subsets are similar. The difference between the duration of the SMTC period of any frequency point to be tested in the frequency point subset to be tested and the duration of the SMTC period of any frequency point to be tested in the other frequency point subsets to be tested is greater than a second preset threshold, indicating that the interval duration between the SMTC periods of the frequency point subsets to be tested after grouping is longer, so as to lengthen the time interval between the frequency point subsets to be tested.

S402: Determine a sixth frequency point to be measured and a seventh frequency point to be measured in each subset of frequency points to be measured.

Among them, the sixth frequency point to be measured is the frequency point to be measured with the smallest SMTC period in the frequency point subset to be measured, and the seventh frequency point to be measured is other frequency points to be measured in the frequency point subset to be measured. Optionally, the seventh frequency point to be measured can be any frequency point to be measured among the other frequency points to be measured in the frequency point subset to be measured, for example, the seventh frequency point to be measured can be the frequency point to be measured with the smallest SMTC period among the other frequency points to be measured, or can be the frequency point to be measured with the largest SMTC period among the other frequency points to be measured.

In this embodiment, when the UE groups multiple frequency points to be measured in a frequency point to be measured set to obtain at least two frequency point subsets to be measured, the sixth frequency point to be measured and the seventh frequency point to be measured in each frequency point subset to be measured can be determined, and then the scheduling position of the sixth frequency point to be measured and the scheduling position of the seventh frequency point to be measured in each frequency point subset to be measured are further determined according to the method described in S301, and finally the frequency points to be measured in each subset are scheduled based on the scheduling position of each frequency point subset to be measured. It should be noted that the sixth frequency point to be measured in this embodiment corresponds to the third frequency point to be measured in the embodiment of FIG. 4, and the seventh frequency point to be measured corresponds to the fourth frequency point to be measured in the embodiment of FIG. 4.

The frequency scheduling method provided in the above embodiment groups each test frequency point in each test frequency point set. On the one hand, the periodic positions of the SMTCs of each test frequency point subset obtained after grouping are lengthened by a certain time, so that the UE can enter a sleep state for a longer period of time within a DRX cycle, or reduce the frequency of the UE's awakening and sleeping conversion within a DRX cycle, thereby reducing the power consumption of the UE, extending the service life of the UE, and improving the user experience of using the UE; on the other hand, the SMTC periodic positions of each test frequency point in each test frequency point subset are distributed more concentratedly, so as to overcome the problem that the scheduling positions of each test frequency point are easily dispersed due to the dispersion of the SMTC periodic positions of each test frequency point in the prior art when determining the scheduling positions of each test frequency point, thereby improving the concentration of the scheduling positions of the test frequency points in each group, and also achieving the purpose of optimizing the scheduling positions of each group of test frequency points, thereby reducing the power consumption of the UE, extending the service life of the UE, and improving the user experience of using the UE.

Further, a method for the UE to determine the scheduling position of each frequency point to be measured in each frequency point subset to be measured is provided. As shown in FIG9, the method includes:

S501, in the discontinuous reception period corresponding to the subset of frequency points to be measured, determining the SMTC periodic positions of the sixth frequency point to be measured and the seventh frequency point to be measured.

This embodiment relates to a method for determining the periodic position of the sixth and seventh frequency points to be measured in each frequency point subset to be measured, and the specific method can be referred to the method described in S301 above, which will not be repeated here. It should be noted that the sixth frequency point to be measured in this embodiment corresponds to the third frequency point to be measured in S301 above, and the seventh frequency point to be measured corresponds to the fourth frequency point to be measured in S301 above.

S502. When the SMTC periodic position of the seventh frequency point to be measured is included between the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured, the first SMTC periodic position after the current SMTC periodic position of the sixth frequency point to be measured is determined as the scheduling position of the sixth frequency point to be measured.

Among them, the current SMTC periodic position of the sixth frequency point to be measured is the SMTC periodic position of the sixth frequency point to be measured that coincides with the paging moment in the discontinuous reception period, or the current SMTC periodic position of the sixth frequency point to be measured is the first SMTC periodic position of the sixth frequency point to be measured after the paging moment.

This embodiment relates to a method for determining the scheduling position of the sixth frequency point to be measured and the seventh frequency point to be measured in each frequency point subset to be measured, and the specific method can be referred to the method described in S302 above, which will not be repeated here. It should be noted that the sixth frequency point to be measured in this embodiment corresponds to the third frequency point to be measured in S302 above, and the seventh frequency point to be measured corresponds to the fourth frequency point to be measured in S302 above.

Optionally, the UE may determine the current SMTC periodic position of the seventh frequency point to be measured as the scheduling position of the seventh frequency point to be measured when the SMTC periodic position of the seventh frequency point to be measured is included between the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured, and the SMTC period of the sixth frequency point to be measured is different from the SMTC period of the seventh frequency point to be measured.

In actual applications, the UE may also schedule the sixth frequency point to be measured, the seventh frequency point to be measured, and the eighth frequency point to be measured in the discontinuous reception period corresponding to the frequency point set to be measured. Following the method of S502, the UE may first determine whether the SMTC periodic position of the seventh frequency point to be measured and the SMTC periodic position of the eighth frequency point to be measured are included between the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured. If the SMTC periodic position of the seventh frequency point to be measured and the SMTC periodic position of the eighth frequency point to be measured are included between the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured, and the SMTC periodic position of the seventh frequency point to be measured and the SMTC periodic position of the eighth frequency point to be measured do not overlap, then the current SMTC periodic position of the seventh frequency point to be measured is determined as the scheduling position of the seventh frequency point to be measured, and the current SMTC periodic position of the eighth frequency point to be measured is determined as the scheduling position of the eighth frequency point to be measured; if the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured are included, then the current SMTC periodic position of the seventh frequency point to be measured is determined as the scheduling position of the seventh frequency point to be measured, and the current SMTC periodic position of the eighth frequency point to be measured is determined as the scheduling position of the eighth frequency point to be measured; if the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured are included, then the current SMTC periodic position of the seventh frequency point to be measured is determined as the scheduling position of the eighth frequency point to be measured; In the case that the next SMTC periodic position of the sixth frequency point to be measured includes the SMTC periodic position of the seventh frequency point to be measured and the SMTC periodic position of the eighth frequency point to be measured, if the SMTC periodic position of the seventh frequency point to be measured coincides with the SMTC periodic position of the eighth frequency point to be measured, the current SMTC periodic position of the seventh frequency point to be measured is determined as the scheduling position of the seventh frequency point to be measured, and the first SMTC periodic position after the current SMTC periodic position of the eighth frequency point to be measured is determined as the scheduling position of the eighth frequency point to be measured.

In another case, when the SMTC periodic position of the seventh frequency point to be measured is not included between the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured, the next SMTC periodic position of the sixth frequency point to be measured is updated to the current SMTC periodic position, and the step of returning to execute is when the SMTC periodic position of the seventh frequency point to be measured is included between the current SMTC periodic position of the sixth frequency point to be measured and the next SMTC periodic position of the sixth frequency point to be measured, and determining the SMTC periodic position after the current SMTC periodic position of the sixth frequency point to be measured as the scheduling position of the sixth frequency point to be measured.

The above embodiments are based on the same method for determining the scheduling position of each frequency point to be measured in the first set of frequency points to be measured as described above. For details, please refer to the above description and will not be repeated here. It should be noted that the sixth frequency point to be measured in this embodiment corresponds to the third frequency point to be measured in the above embodiment, the seventh frequency point to be measured corresponds to the fourth frequency point to be measured in the above embodiment, and the eighth frequency point to be measured corresponds to the fifth frequency point to be measured in the above embodiment.

In summary of all the above embodiments, the present application further provides a method for scheduling each frequency point to be measured in each set of frequency points to be measured or each subset of frequency points to be measured, as shown in FIG10, the method comprising:

S601, determine a target measurement gap and all frequencies to be measured in a current DRX cycle.

In the idle state of the existing NR system, since a set of measured frequencies or all the measured frequencies in a subset of measured frequencies can be scheduled within a DRX cycle, and all the measured frequencies to be scheduled in each DRX cycle have the same scheduling method, this embodiment takes a DRX cycle, i.e., the current DRX cycle, as an example for explanation.

The target measurement gap may be any measurement gap in the current DRX cycle, or may be a measurement gap determined in advance by the UE according to measurement requirements, for example, as shown in FIG4A, a schematic diagram of measurement gaps in an idle state, in which P0 is a paging time in each DRX cycle, there is a measurement gap gap1 before P0, and there is a measurement gap gap2 after P0. In actual applications, the UE may schedule all the frequencies to be measured in gap1, or may schedule all the frequencies to be measured in gap2. All the frequencies to be measured are all the frequencies to be measured included in a set of frequencies to be measured that need to be scheduled in the current DRX cycle, or may be all the frequencies to be measured included in a subset of frequencies to be measured. All the frequencies to be measured may include frequencies to be measured of the same frequency, or may include frequencies to be measured of different frequencies.

In this embodiment, when the UE groups multiple frequency points to be measured based on the above embodiment to obtain multiple frequency point sets to be measured, or further groups the frequency points to be measured in the frequency point set to be measured to obtain multiple frequency point subsets to be measured, and determines the DRX cycle corresponding to the frequency point set to be measured based on the above steps, all the frequency points to be measured that need to be measured in the current DRX cycle can be determined. In addition, the UE can determine the available measurement gaps in the current DRX cycle in advance according to the current DRX cycle and the paging time, and further select a measurement gap from the available measurement gaps as the target measurement gap, for example, in the DRX cycle n shown in FIG. 4A, gap2 is determined as the target measurement gap, and then all the frequency points to be measured are scheduled in the target measurement gap.

S602: Group the frequency points to be measured according to the SMTC period of each frequency point to be measured to obtain at least two frequency point groups to be measured.

This embodiment relates to a method for grouping multiple frequency points to be measured, which is consistent with the grouping method described in S101 in the embodiment of Figure 2. For detailed method description, please refer to the above content and will not be repeated here.

S603: Determine the scheduling position of each frequency point to be measured in each frequency point group to be measured in the target measurement gap according to the SMTC period of each frequency point to be measured.

Among them, the interval duration between the scheduling positions of each frequency point group to be tested is greater than the preset duration; the scheduling position of the frequency point group to be tested is the scheduling position of any frequency point to be tested in the frequency point group to be tested.

The above-mentioned preset duration is a duration determined in advance by the UE according to actual scheduling requirements, and is used to measure the length of the interval duration between the scheduling positions of each frequency group to be measured. When the interval duration between the scheduling positions of each frequency group to be measured is greater than the preset duration, it is determined that the interval duration between the scheduling positions of each frequency group to be measured is longer; when the interval duration between the scheduling positions of each frequency group to be measured is not greater than the preset duration, it is determined that the interval duration between the scheduling positions of each frequency group to be measured is shorter.

In this embodiment, after the UE groups all the frequency points to be measured, the scheduling position of each group of frequency points to be measured can be determined. Since the method for determining the scheduling position of each group of frequency points to be measured is the same, this embodiment takes one group of frequency points to be measured as an example for description. Before the UE schedules each frequency point to be measured in a group, it is necessary to first determine the scheduling position of each scheduling frequency point in the group. Specifically, according to the SMTC period of each frequency point to be measured in the group, one SMTC periodic position of each frequency point to be measured can be selected in turn within the target measurement gap to be determined as the scheduling position of each frequency point to be measured, so that the scheduling positions of each frequency point to be measured do not overlap. For example, as shown in the schematic diagram of Figure 10A, the frequency point group #1 to be measured includes three frequency points to be measured F1, F2 and F3, and their SMTC periods are 5ms, 10ms, and 20ms, respectively. Then, an SMTC periodic position of the frequency point to be measured F1 (the position indicated by a in the figure) can be determined as the scheduling position of F1, an SMTC periodic position of the frequency point to be measured F2 (the position indicated by b in the figure) can be determined as the scheduling position of F2, and an SMTC periodic position of the frequency point to be measured F3 (the position indicated by c in the figure) can be determined as the scheduling position of F3. After the UE determines the scheduling position of each frequency point to be measured in each group of frequency points to be measured, it can schedule each frequency point to be measured so as to measure each frequency point to be measured later.

The frequency scheduling method provided in the above embodiment determines the target measurement gap and all the frequencies to be measured in the current DRX cycle, groups the frequencies to be measured according to the SMTC cycle of each frequency to be measured, obtains at least two frequency groups to be measured, and determines the scheduling position of each frequency to be measured in each frequency group to be measured in the target measurement gap according to the SMTC cycle of each frequency to be measured, so as to achieve the scheduling of all the frequencies to be measured. Among them, since the interval time between the scheduling positions of each frequency group to be measured is determined to be greater than the preset time, the time length between the scheduling positions of each frequency group to be measured is lengthened, so that the UE can enter a sleep state for a longer period of time after scheduling each frequency to be measured in each frequency group to be measured in the current discontinuous reception cycle, thereby reducing the power consumption of the UE. In addition, before determining the scheduling positions of all the frequency points to be measured, the UE also groups all the frequency points to be measured, so that the SMTC periodic position distribution of the frequency points to be measured in each group is relatively concentrated, which overcomes the problem that when determining the scheduling positions of the frequency points to be measured in the prior art, the scheduling positions of the frequency points to be measured are easily dispersed due to the dispersion of the SMTC periodic positions of the frequency points to be measured themselves, improves the concentration of the scheduling positions of the frequency points to be measured in each group, achieves the purpose of optimizing the scheduling positions of the frequency points to be measured in each group, thereby reducing the power consumption of the UE, extending the service life of the UE, and improving the user experience of using the UE.

In one embodiment, when the UE determines the scheduling position of each frequency point to be measured in each frequency point group to be measured, the scheduling position of each frequency point to be measured in each frequency point group to be measured can be concentrated as much as possible, so that the UE can complete the scheduling of all the frequency points to be measured in each frequency point group to be measured in a short period of time, thereby achieving the purpose of reducing the power consumption of the UE. Based on this, the present application provides a scheduling method for each frequency point group to be measured to achieve the above effect, and the following embodiment specifically describes the method.

FIG11 is a specific implementation of S603 in the embodiment of FIG10. As shown in FIG11, the implementation includes:

S701: Determine a first target frequency point in each frequency point group to be measured.

The first target frequency point is the frequency point to be measured with the smallest SMTC period in the frequency point group to be measured.

In this embodiment, when the UE determines the scheduling position of each frequency point to be measured in a frequency point group to be measured, the frequency point to be measured with the smallest SMTC period, i.e., the first target frequency point, can be firstly screened out from the frequency point group to be measured, for example, taking the frequency point group to be measured #1 in FIG. 10A as an example, the frequency point to be measured F1 in the group is the frequency point with the smallest SMTC period, so that the scheduling position of other frequency points to be measured in the frequency point group to be measured can be determined according to the position of the SMTC period of the first target frequency point.

S702: Determine the scheduling position of each frequency point to be measured in the frequency point group to be measured according to the SMTC period of the first target frequency point and the SMTC periods of other frequency points to be measured in the frequency point group to be measured.

When the UE obtains the SMTC period of the first target frequency point in the frequency point group to be measured and the SMTC periods of other frequency points to be measured, it can first select an SMTC periodic position of the first target frequency point to be determined as the scheduling position of the first target frequency point, and then correspondingly select an SMTC periodic position corresponding to each other frequency point to be measured as the scheduling position of each frequency point to be measured, as long as the scheduling positions of each frequency point to be measured in the frequency point group to be measured do not overlap.

Optionally, a specific implementation method is provided in which the UE determines the scheduling position of each frequency point to be measured in the corresponding frequency point group to be measured according to the SMTC period of the first target frequency point, as shown in Figure 12, and the method includes:

S801, determine the current SMTC periodic position and the next SMTC periodic position of the first target frequency according to the paging time.

Among them, the current SMTC periodic position of the first target frequency is the SMTC periodic position of the first target frequency that coincides with the paging moment, or the current SMTC periodic position of the first target frequency is the first SMTC periodic position of the first target frequency after the paging moment.

It should be noted that the current SMTC periodic position of the first target frequency point can be determined by the frame number or subframe number of the SMTC period of the first target frequency point. The definition of the frame number or subframe number is described in 3GPP 38.331. For example, see the following description:

According to 3GPP 38.331

Section 5.5.2.10 Reference signal measurement timing configuration The specific method is as follows:

The UE shall setup the first SS/PBCH block measurement timingconfiguration (SMTC)in accordance with the received periodicityAndOffsetparameter(providing Periodicity and Offset value for the following condition)in the smtc 1configuration. The first subframe of each SMTC occasion occursat an SFN and subframe of the NR SpCell meets the following condition:

SFN mod T＝(FLOOR(Offset/10));

if the Periodicity is larger than sf5:

subframe = Offset mod 10;

else:

subframe=Offset or(Offset+5);

with T＝CEIL(Periodicity/10).

Wherein, subframe represents a frame number or a subframe number.

In this embodiment, since the UE can determine the target measurement gap as the measurement gap before the paging moment (such as gap1 in FIG. 4A) or the measurement gap after the paging moment (such as gap2 in FIG. 4A), the UE can further determine the current SMTC periodic position and the next SMTC periodic position of the first target frequency point according to the paging moment when determining the target measurement gap. In this embodiment, the measurement gap after the paging moment is used as the target measurement gap for illustration. The UE can determine the SMTC periodic position of the first target frequency point that coincides with the paging moment as the current SMTC periodic position of the first target frequency point, and determine the next SMTC periodic position of the first target frequency point relative to the current SMTC periodic position of the first target frequency point, for example, as shown in FIG. 4A, smtc n is the current SMTC periodic position of the first target frequency point, and smtc n+1 is the next SMTC periodic position of the first target frequency point.

S802, determine whether there are SMTC periodic positions of other frequency points to be measured between the current SMTC periodic position of the first target frequency point and the next SMTC periodic position, and obtain a determination result.

When the UE determines the current SMTC periodic position and the next SMTC periodic position of the first target frequency point, it can further determine whether there are SMTC periodic positions of other measured frequencies within the time interval between the current SMTC periodic position and the next SMTC periodic position of the first target frequency point, and select different scheduling methods to determine the scheduling positions of each frequency point to be measured in the frequency point group to be measured according to different judgment results. For example, as shown in FIG12A, it is determined whether the time interval between smtc n and smtc n+1 contains the SMTC periodic positions of other frequency points to be measured, and between smtc n and smtc n+1 in FIG12A, a SMTC periodic position b of F2 and a SMTC periodic position c of F3 are included.

S803, determine the scheduling position of each frequency point to be measured in the frequency point group to be measured according to the judgment result. If the judgment result is that there are SMTC periodic positions of other frequency points to be measured, execute step S804; if the judgment result is that there are no SMTC periodic positions of other frequency points to be measured, execute step S805.

If the judgment result is that there are SMTC periodic positions of other frequency points to be measured, the UE can further determine the scheduling position of each frequency point to be measured in the corresponding frequency point group to be measured based on the SMTC periodic positions of the first target frequency point and the other frequency points to be measured. For the specific determination method, see the following step S804; if the judgment result is that there are no SMTC periodic positions of other frequency points to be measured, then specifically execute the following step S805.

S804, determining the next SMTC periodic position of the first target frequency point as the scheduling position of the first target frequency point, and determining the scheduling position of each other frequency point to be measured according to the current SMTC periodic position of each other frequency point to be measured.

When the above judgment result is that there are SMTC periodic positions of other frequency points to be measured, the next SMTC periodic position of the first target frequency point can be determined as the scheduling position of the first target frequency point, and then the scheduling positions of other frequency points to be measured can be determined in turn. When determining specifically, an SMTC periodic position of each other frequency point to be measured that is closest to the scheduling position of the first target frequency point can be determined as the scheduling position of each other frequency point to be measured. For example, in the frequency point group #1 to be measured as shown in Figure 12A, F1 is the first target frequency point, and the next SMTC periodic position of the first target frequency point is determined to be the scheduling position of the first target frequency point (the position indicated by a in the figure), an SMTC periodic position b of the other frequency point F2 to be measured is the scheduling position of F2, and an SMTC periodic position c of the other frequency point F3 to be measured is the scheduling position of F3.

S805, taking the next SMTC periodic position of the first target frequency point as the new current SMTC periodic position of the first target frequency point, and returning to execute the step of determining whether there are SMTC periodic positions of other frequency points to be measured between the current SMTC periodic position of the first target frequency point and the next SMTC periodic position.

When the above judgment result is that there are no SMTC periodic positions of other frequency points to be measured, the current SMTC periodic position of the first target frequency point can be slid to the next SMTC periodic position, that is, the next SMTC periodic position of the first target frequency point is used as the new current SMTC periodic position of the first target frequency point, and then the next SMTC periodic position from the new current SMTC periodic position is determined as the new next SMTC periodic position of the first target frequency point, and then the step S802 is returned to execute, based on the new current SMTC periodic position and the new next SMTC periodic position of the first target frequency point, a new judgment result is obtained again, and then the scheduling position of each frequency point to be measured in the frequency point group to be measured is determined according to the new judgment result.

Optionally, when the UE determines the scheduling positions of other frequency points to be measured, as shown in FIG13, the following method may also be used:

S901, determine whether other frequency points to be measured include overlapping frequency points, if other frequency points to be measured include overlapping frequency points, execute step S902, if other frequency points to be measured do not include overlapping frequency points, execute step S903.

Among them, the overlapping frequency point refers to the frequency point with the same SMTC periodic position among other frequency points to be measured. For example, if the SMTC period of frequency point F1 is 10ms and the SMTC period of frequency point F2 is also 10ms, then the SMTC periodic positions of frequency points F1 and F2 are the same, that is, frequency points F1 and F2 are overlapping frequency points.

In actual applications, there may be overlapping frequencies in a frequency group to be measured. Therefore, it is necessary to first determine whether the other frequency groups to be measured contain overlapping frequencies. If overlapping frequencies are contained, the method described in step S902 is executed to determine the scheduling position of the overlapping frequencies so that the scheduling positions of the overlapping frequencies are staggered to avoid conflict scheduling problems. If no overlapping frequencies are contained, the method described in step S903 is executed to determine the scheduling positions of other frequency groups to be measured.

S902, determine the current SMTC periodic position of the second target frequency point in the overlapping frequency points as the scheduling position of the second target frequency point, use any other overlapping frequency points in the overlapping frequency points as the new second target frequency point, and use the next SMTC periodic position of any other overlapping frequency points as the current SMTC periodic position of the new second target frequency point, and return to execute the step of determining the current SMTC periodic position of the second target frequency point in the overlapping frequency points as the scheduling position of the second target frequency point until the scheduling positions of all conflicting frequency points are determined; if there is an unscheduled frequency point to be tested in addition to the overlapping frequency points in other frequency points to be tested, then determine the current SMTC periodic position of an unscheduled frequency point to be tested as the scheduling position of an unscheduled frequency point to be tested; if there are multiple unscheduled frequency points to be tested in addition to the overlapping frequency points in other frequency points to be tested, then return to execute the step of determining the first target frequency point in each frequency point group to be tested until the scheduling positions of all frequency points to be tested in each frequency point group to be tested are determined.

The second target frequency point may be any frequency point among the overlapping frequency points. The current SMTC periodic position of the second target frequency point is the SMTC periodic position of the second target frequency point that coincides with the paging time, or the current SMTC periodic position of the second target frequency point is the first SMTC periodic position of the second target frequency point after the paging time.

The method described in the above steps is exemplified. As shown in FIG. 13A, all the test frequencies in the discontinuous reception cycle DRX cycle n are F1, F2, F3, F4, F5 and F6, and the corresponding SMTC periods are 5ms, 10ms, 10ms, 40ms, 80ms and 160ms respectively. The six test frequencies are divided into two groups: test frequency group #1 and test frequency group #2. The test frequency group #1 includes the test frequencies F1, F2 and F3, and the test frequency group #2 includes the test frequencies F4, F5 and F6. The test frequency group #1 is taken as an example for explanation. According to step S802, it can be determined that the time interval between the current SMTC periodic position (smtc n) of the test frequency F1 and the next SMTC periodic position (smtc n+1) includes the test frequencies F2 and F3. SMTC periodic position, and the measured frequency points F2 and F3 have the same SMTC periodic position, so F2 and F3 are overlapping frequency points, and any frequency point among F2 and F3 is further used as the second target frequency point. In the figure, F2 is used as the second target frequency point, and then the current SMTC periodic position of F2 can be determined as the scheduling position of F2, referring to the SMTC periodic position b of F2 in FIG13A, and then the other overlapping frequency point F3 is used as the new second target frequency point, and the next SMTC periodic position of F3 is used as the current SMTC periodic position of the new second target frequency point, and finally the current SMTC periodic position of the new second target frequency point F3 is used as the scheduling position of the new second target frequency point, for example, referring to FIG13A where F3 is the new second target frequency point, and the corresponding scheduling position of F3 is the SMTC periodic position c of F3.

After determining the scheduling positions of the overlapping frequency points in other frequency points to be measured, it is possible to further determine whether the other frequency points to be measured include any unscheduled frequency points to be measured, and the number of such unscheduled frequency points to be measured. If such a frequency point to be measured includes an unscheduled frequency point to be measured, the current SMTC periodic position of such unscheduled frequency point to be measured is directly determined as the scheduling position of such unscheduled frequency point to be measured. If such a frequency point to be measured includes multiple unscheduled frequency points to be measured, the process returns to execute the above step S801 to determine the scheduling positions of multiple unscheduled frequency points to be measured. The above method is repeated repeatedly until the scheduling positions of all frequency points to be measured in the frequency point group to be measured are determined.

S903, determine the frequency point to be tested with the largest SMTC period among other frequency points to be tested as the third target frequency point, and determine the current SMTC periodic position of the third target frequency point as the scheduling position of the third target frequency point; if there is an unscheduled frequency point to be tested in addition to the third target frequency point among other frequency points to be tested, then determine the current SMTC periodic position of an unscheduled frequency point to be tested as the scheduling position of an unscheduled frequency point to be tested; if there are multiple unscheduled frequency points to be tested in addition to the third target frequency point among other frequency points to be tested, then return to the step of determining the first target frequency point in each frequency point group to be tested until the scheduling positions of all frequency points to be tested in each frequency point group to be tested are determined.

Among them, the current SMTC periodic position of the third target frequency is the SMTC periodic position of the third target frequency that coincides with the paging moment, or the current SMTC periodic position of the third target frequency is the first SMTC periodic position of the third target frequency after the paging moment.

The method described in the above steps is exemplified as shown in FIG. 13A , where the frequency point group #2 to be tested is taken as an example for explanation. According to step S801, it can be determined that the time interval between the current SMTC periodic position (smtc n) of the frequency point F4 to be tested and the next SMTC periodic position (smtc n+1) includes the SMTC periodic positions of other frequency points F5 and F6 to be tested. Next, the frequency point F6 with the largest SMTC period is selected as the third target frequency point among the frequency points F5 and F6 to be tested. Then, the current SMTC periodic position f of the other frequency point F6 to be tested is determined as the scheduling configuration of the frequency point F6 to be tested. Then, it is further determined whether the frequency point group #2 to be tested still includes unscheduled frequency points to be tested. At this time, the frequency point group #2 to be tested still includes an unscheduled frequency point F5 to be tested. Then, the current SMTC periodic position of the frequency point F5 to be tested is directly determined as the scheduling position of the frequency point F5 to be tested.

The frequency scheduling method described in the above embodiment takes into account scheduling scenarios with overlapping frequencies and scheduling scenarios without overlapping frequencies, that is, it fully takes into account any scheduling scenarios that may occur in actual applications. Therefore, the scheduling method provided in the above embodiment can be applied to frequency scheduling in any scenario and has a wider range of applications.

In one embodiment, since three grouping methods are provided in the description of S101 in the embodiment of FIG. 2 , this embodiment provides an implementation of the above S101 for the first grouping method, and S302 is used as an example for illustration, that is, the above S302 "groups the frequency points to be measured according to the SMTC period of each frequency point to be measured to obtain at least two frequency point groups to be measured" includes: grouping the frequency points to be measured according to the SMTC period of each frequency point to be measured and at least one preset period threshold value to obtain at least two frequency point groups to be measured.

The preset period threshold may be determined in advance by the UE according to grouping requirements.

In this embodiment, when the UE obtains all the frequencies to be measured, all the frequencies to be measured can be further grouped according to the preset period threshold value, and at least two frequency groups to be measured can be obtained. For example, as shown in FIG13A, assuming that the preset period threshold value can be set to 30ms, the frequencies to be measured F1, F2 and F3 with SMTC periods less than 30ms are grouped into one group to obtain frequency group #1 to be measured; the frequencies to be measured F4, F5 and F6 with SMTC periods greater than 30ms are grouped into one group to obtain frequency group #2 to be measured. By using the above method for grouping, the SMTC periodic positions of each test frequency point in the test frequency point group #1 or the test frequency point group #2 can be relatively close, so that the scheduling positions of each test frequency point in each test frequency point group can be more concentrated, for example, referring to FIG. 13A, the scheduling position a of F1, the scheduling position b of F2 and the scheduling position c of F3 in the test frequency point group #1 are more concentrated, and the scheduling position d of F4, the scheduling position e of F5 and the scheduling position f of F6 in the test frequency point group #2 are more concentrated, so that the scheduling position of the test frequency point group #1 and the scheduling position of the test frequency point group #2 can be separated by a longer time, so that the UE can enter a longer sleep time between the scheduling position of the test frequency point group #1 and the scheduling position of the test frequency point group #2, so as to reduce the power consumption of the UE. In addition, the frequency of the conversion between UE wake-up and sleep can be reduced, and the power consumption of the UE can be reduced to a certain extent.

In practical applications, since the UE can schedule the frequency point to be measured in any measurement gap in the current discontinuous reception period, when multiple frequency points to be measured are scheduled at one time, selecting a suitable measurement gap can improve the scheduling efficiency of the frequency points to be measured. Based on this, the present application provides a method for specifically determining a target measurement gap. As shown in FIG14, the “determining a target measurement gap in the current discontinuous reception period” in the above S601 includes:

S1001, receive SIB1 information, and determine the paging time according to the SIB1 information.

The paging time is the time when the paging message is received in the discontinuous reception period, which can be calculated by the UE according to the relevant configuration parameters. In this embodiment, the UE can receive the system information block SIB1 information sent by the base station/network side, and further extract the relevant configuration parameters from the SIB1 information, and calculate the paging time according to the relevant configuration parameters.

S1002: Determine at least two candidate measurement gaps according to the paging time and the current discontinuous reception cycle.

The candidate measurement gap is a measurement gap that can be used for frequency scheduling in the current discontinuous reception cycle. In this embodiment, when the UE determines the current discontinuous reception cycle and the paging time, it can select the time period before the paging time in the current discontinuous reception cycle and the time period after the paging time as the candidate measurement gap. For example, in the schematic diagram shown in FIG4A, P0 is the calculated paging time, gap1 and gap2 are available measurement gaps, that is, two candidate measurement gaps.

S1003: Determine a measurement gap with the longest duration among the candidate measurement gaps as a target measurement gap.

When the UE determines multiple candidate measurement gaps, the measurement gap with the longest duration can be further determined as the target measurement gap. Since the duration of the target measurement gap is long, it is easy to complete the scheduling of all the frequencies to be measured at one time, thereby improving the scheduling efficiency of all the frequencies to be measured, and when the number of the frequencies to be measured is large, the problem that some frequencies to be measured cannot be scheduled normally can be avoided accordingly.

The scheduling method provided in any of the above embodiments can be applied to a variety of scheduling scenarios in the idle state of the NR system, that is, a scheduling scenario in which different frequencies are scheduled in different discontinuous reception cycles, and a scheduling scenario in which multiple frequencies are scheduled in one discontinuous reception cycle, so the frequency scheduling method is more widely used. Moreover, when scheduling different frequencies in different discontinuous reception cycles, by moving the frequencies to be measured in other discontinuous reception cycles to the current discontinuous reception cycle for scheduling, an idle discontinuous reception cycle appears in other discontinuous reception cycles, thereby reducing the scheduling consumption of the UE and thus reducing the power consumption of the UE. When scheduling multiple frequencies in one discontinuous reception cycle, by optimizing the scheduling positions of the frequencies to be measured in the current discontinuous reception cycle, the scheduling positions of the frequencies to be measured in the current discontinuous reception cycle are more concentrated, and the scheduling positions between each group of frequencies to be measured are extended for a longer period of time, thereby increasing the duration of the UE in the sleep state, and also reducing the frequency of UE wake-up and sleep conversion, thereby greatly reducing the power consumption of the UE.

It should be understood that, although the steps in the flowcharts of FIG. 2-14 are sequentially displayed according to the indications of the arrows, these steps are not necessarily executed sequentially in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in FIG. 2-14 may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a portion of the steps or stages in other steps.
