Description

Gap selection method and device

technical field

The present invention relates to the field of communications, and in particular, to a Gap selection method and device.

Background technique

In a wireless communication system, a user equipment (English: user equipment; abbreviated as: UE) needs to measure the signals of neighboring cells adjacent to the serving cell while communicating with the base station that controls the serving cell in the serving cell (Cell). In order to perform cell handover at an appropriate timing, that is, handover the neighboring cell to the serving cell of the UE. Due to the limitation of the transceiver, the UE cannot maintain communication with the base station and perform neighbor cell measurement at the same time. At this time, the base station needs to configure a measurement gap for the UE, and the measurement gap is the period during which the UE performs measurement. The UE interrupts communication with the base station during the measurement gap, and performs neighbor cell measurement; during the time outside the measurement gap, the UE maintains communication with the base station. Specifically, the base station configures a measurement gap mode for the UE, and the measurement gap mode specifies the time when the measurement gap occurs. For example, in a measurement gap mode, a measurement gap occurs every 40ms.

Device to Device (English: Device to Device; Abbreviation: D2D) refers to a mode in which UEs discover and communicate with each other through sidelinks (English: Sidelink; Abbreviation: SL). The information is transmitted to another UE without being relayed by the base station. The D2D resources used by the UE on the SL are part of the resources of the serving cell or neighboring cells. Due to the limitation of the transceiver, the UE cannot transmit data packets on the SL and maintain communication with the base station at the same time. At this time, the base station needs to configure the SL Gap for the UE. The SL Gap is the period during which the UE performs sidelink transmission or reception (period ). The UE interrupts communication with the base station in the SL Gap, and transmits data packets on the SL; during the time outside the SL Gap, the UE maintains communication with the base station.

As required, the base station may configure measurement gap and SL gap for the same UE. When the UE cannot transmit data packets in the SL while performing neighbor measurement, the base station needs to configure the SL gap and measurement gap completely staggered from each other for the UE. Gap, so that the SL Gap and the measurement gap do not conflict with each other, so that the UE can transmit data packets on the SL in the SL Gap without performing neighbor cell measurement; in the measurement gap, perform neighbor cell measurement without transmitting data packets on the SL ; Maintain communication with the base station outside the measurement gap and outside the SL Gap. The above configuration requirements make it very complicated for the base station to configure the measurement Gap and SL Gap for the UE, which affects the efficiency of Gap configuration.

It solves the problems of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

Please refer to FIG. 3A , which shows a method flowchart of another Gap selection method provided by an embodiment of the present invention. In this embodiment, the UE selects the measurement Gap or the SL Gap according to the relative priority between the measurement Gap and the SL Gap . The Gap selection method can include:

Step 301, the base station determines the measurement gap configured for the UE.

When the method is applied to a long term evolution (English: long term evolution; LTE for short) system, the base station is specifically an eNB (eNodeB); When this method is applied to wireless fidelity (English: Wireless Fidelity; English: WiFi), the base station is specifically an access point (English: accesspoint; abbreviation: AP).

Usually, a UE includes one transceiver, and one transceiver can only send and receive signals on one frequency point at the same time. Therefore, when the adjacent cell of the UE's serving cell and the serving cell have different frequencies, the base station needs to configure the measurement gap for the UE. In order to make the UE interrupt the communication with the base station during the measurement gap, and perform the neighbor cell measurement; in the time outside the measurement gap, the UE maintains the communication with the base station and does not perform the neighbor cell measurement.

In this embodiment, the base station configures the occurrence time of the measurement gap for the UE according to many factors, wherein the occurrence time of the measurement gap is determined by the start time, the occurrence period of the measurement gap, and the duration of the measurement gap. The start time may be directly issued by the base station, or may be calculated by the UE according to the offset after the base station issues the offset, which is not limited in this embodiment.

This embodiment is described by taking an example that the base station configures the occurrence period of the measurement gap for the UE according to the number of inter-frequency to be measured. Specifically, when the number of different frequencies is large, the occurrence period of the measurement gap is configured to be smaller; when the number of different frequencies is small, the occurrence period of the measurement gap is configured to be larger.

When configuring the duration of each measurement gap, in one possible implementation, the base station configures the duration of each measurement gap when configuring the measurement gap; in another possible implementation, the UE configures the duration of each measurement gap. Determine how long each measurement gap lasts.

Wherein, when the UE determines the duration of each measurement gap, the UE can read the duration of each measurement gap specified in the communication protocol; or, the UE can determine the duration of each measurement gap by itself. When the UE itself determines the duration of each measurement gap, the UE may notify the base station of the duration of each measurement gap, or may not notify the base station, which is not limited in this embodiment.

Step 302, the base station generates configuration information, where the configuration information is used to indicate the time when the measurement gap occurs.

Step 303, the base station sends the configuration information to the UE.

Step 304, the UE receives the configuration information sent by the base station.

Step 305, the UE judges whether the measurement gap conflicts with the SL gap according to the time when the measurement gap appears and the time when the SL gap appears, and the time when the SL gap appears is configured according to a predetermined policy.

Among them, the time when the SL Gap appears is determined by the start time, the occurrence period of the SL Gap, and the duration of the SL Gap.

In this embodiment, the configuration of the time at which the SL Gap appears may be issued by the base station or determined by the UE. The following two implementations will be introduced respectively:

When the configuration of the occurrence period of the SL gap is issued by the base station, the base station will configure the occurrence period of the SL gap for the UE according to many factors. For example, the base station configures the occurrence period of the SL gap for the UE according to the available resources, so as to ensure that there are available resources for the UE. Transport packets in SL Gap. The transmission of the data packet by the UE in the SL Gap may specifically include: the UE receives the data packet on the SL through the SL Gap, or the UE sends the data packet on the SL through the SL Gap.

It should be noted that, when configuring the occurrence period of the SL Gap, in a possible manner, the base station configures the occurrence period for each SLGap. For example, the occurrence period of each SL Gap is 40ms, and at this time, an occurrence period of each SL Gap occurs every 40ms. SL Gap; in another possible implementation manner, the base station regards a predetermined number of SL gaps as a group, and configures the occurrence period of SL Gap groups, for example, three SL gaps are used as a group, and each SL Gap grouping The occurrence period is 40ms, and an SL Gap packet appears every 40ms at this time.

When configuring the duration of the SL Gap, in a possible implementation manner, the base station configures the duration of the SL Gap when configuring the occurrence period of the SL Gap; in another possible implementation manner, it is determined by the UE The duration of the SL Gap. Wherein, when the UE determines the duration of the SL Gap, the UE can read the duration of the SLGap specified in the communication protocol; or the UE can determine the duration of the SL Gap by itself. When the UE itself determines the duration of the SL Gap, the UE may notify the base station of the duration of the SL Gap, or may not notify the base station, which is not limited in this embodiment.

It should be noted that when configuring the duration of the SL Gap, in one possible manner, the base station configures the duration for each SL Gap, for example, the duration of each SL Gap is 10ms; in another possibility In the implementation of the SL gap, the base station regards a predetermined number of SL Gap as a group, and configures the duration of the SL Gap grouping. At this time, three SL gaps with a duration of 10ms are configured within a duration of 100ms. For example, it is configured that the SL Gap occurs at the 10th ms, the 30th ms, and the 50th ms, or the SL Gap is configured to occur at the 20th ms, 60 ms, and 80 ms, which is not limited in this embodiment.

The base station may also add information for indicating the time when the SL Gap appears to the configuration information in step 302, so as to save the wasteful signaling that the base station sends these two kinds of information through additional configuration information.

When the configuration of the occurrence period of the SL Gap is determined by the UE, the UE may read the occurrence period of the SL Gap specified in the communication protocol; or, the UE may determine the occurrence period of the SL Gap by itself. When the UE itself determines the occurrence period of the SL Gap, the UE may notify the base station of the occurrence period of the SL Gap, or may not notify the base station, which is not limited in this embodiment. The process of determining the occurrence period of the SL Gap by the UE itself is the same as the process of configuring the occurrence period of the SL Gap by the base station, which is not repeated here.

The UE also needs to determine the duration of the SL Gap. In one possible implementation, the base station configures the duration of the SLGap; in another possible implementation, when the UE determines the occurrence period of the SL Gap, Determines how long the SLGap will last. Wherein, when the UE determines the duration of the SL Gap, the UE can read the duration of the SL Gap specified in the communication protocol; or, the UE can determine the duration of the SL Gap by itself. When the UE itself determines the duration of the SL Gap, the UE may notify the base station of the duration of the SL Gap, or may not notify the base station, which is not limited in this embodiment.

Regardless of whether the configuration of the SL Gap is configured by the base station or determined by the UE, there is no need to consider whether the measurement Gap and SLGap will conflict, thereby reducing the requirements for configuring the measurement Gap and the SL Gap and improving the efficiency of configuring the Gap. The conflict between the measurement gap and the SL gap refers to the conflict between the time when the measurement gap appears and the time when the SL gap appears. Please refer to the schematic diagram of the measurement Gap and the SL Gap shown in FIG. 3B , wherein the third SL Gap conflicts with the second measurement Gap, and the fourth SL Gap conflicts with the third measurement Gap.

After determining the measurement gap and the SL gap, the UE performs timing, performs neighbor cell measurement within the time when the measurement gap appears, and transmits data packets on the SL within the time when the SL gap appears. Since the measurement gap and the SL gap may collide, and the UE can only select one of the measurement gap and the SL gap at the same time, before the UE performs neighbor measurement in the measurement gap or transmits data packets on the SL through the SL gap, It is also necessary to judge whether the measurement Gap conflicts with the SL Gap.

Specifically, according to the time when the measurement gap appears and the time when the SL gap appears, it is determined whether the measurement gap conflicts with the SL gap, including:

1) Determine the time period corresponding to the next measurement Gap after the current moment according to the time when the measurement gap appears, and determine the time period of the next SL Gap after the current moment according to the time when the SL Gap appears, and determine the time period corresponding to the measurement gap and the SL gap. Whether the time periods of Gap overlap, the minimum value of the time period corresponding to the measurement gap is the time period for measuring the gap, and the maximum value of the time period corresponding to the measurement gap is the sum of the time period for measuring the gap and the time period required for the UE to switch from the measurement gap to the SL Gap ;or,

2) Determine the time period corresponding to the next SL Gap after the current moment according to the time when the SL Gap appears, and determine the time period for the next measurement Gap after the current time according to the time when the measurement Gap appears, and determine the time period corresponding to the SL Gap and the measurement Whether the periods of Gap overlap, the minimum value of the period corresponding to the SL Gap is the period of the SL Gap, and the maximum value of the period corresponding to the SL Gap is the sum of the period of the SL Gap and the period required for the UE to switch from the SL Gap to measuring the Gap .

When a measurement gap appears after the current time, locate the first time backward based on the start time of the measurement gap to obtain the first time, and detect whether there will be an SL gap within the time period determined by the start time and the first time. When there is an SL Gap within the time period, it is determined that the measurement gap and the SL Gap conflict; when there is no SL Gap within the time period, it is determined that the measurement gap and the SL Gap will not conflict, and the first duration is the smallest The value is the duration of Gap measurement, and the maximum value is the duration obtained by adding the first predetermined duration to the duration of Gap measurement. The first predetermined duration is the duration required for the UE to switch from the measurement Gap to the SL Gap. In actual implementation, the first predetermined duration may be set to 0.5ms, or may be set to other values, which is not limited in this embodiment. or,

When an SL Gap appears after the current time, locate the second time backward based on the start time of the SL Gap to obtain the second time, and detect whether there will be a measurement gap within the time period determined by the start time and the second time. When a measurement gap occurs within the time period, it is determined that the SL Gap conflicts with the measurement gap; when there is no measurement gap within the time period, it is determined that the SL gap and the measurement gap do not conflict, and the second duration is the smallest The value is the duration of the SL Gap, and the maximum value is the duration obtained by adding the duration of the SL Gap to the second predetermined duration, and the second predetermined duration is the duration required for the UE to switch from the SL Gap to measuring the Gap. In actual implementation, the second predetermined duration may be set to 0.5 ms, or may be set to other values, and the second predetermined duration is the same as or different from the first predetermined duration, which is not limited in this embodiment.

Step 306, when the measurement Gap conflicts with the SL Gap, the UE obtains the relative priority between the measurement Gap and the SL Gap, and the relative priority between the measurement Gap and the SL Gap is issued by the base station, or the measurement Gap and the SL Gap The relative priority between SL gaps is determined by the UE.

In one possible implementation, the base station delivers the relative priority between the measurement Gap and the SL Gap; in another possible implementation, the UE decides the relative priority between the measurement Gap and the SL Gap. Wherein, when the UE determines the relative priority between the measurement Gap and the SL Gap, the UE can read the relative priority between the measurement Gap and the SL Gap specified in the communication protocol; or the UE can decide to measure the Gap and the SL Gap by itself Relative priority between gaps. When the UE itself decides to measure the relative priority between the Gap and the SL Gap, the UE may notify the base station of the relative priority between the measurement Gap and the SL Gap, or may not notify the base station, which is not limited in this embodiment.

When the relative priority between the measurement Gap and the SL Gap is delivered by the base station, the method provided in this embodiment further includes: the base station sends the relative priority between the measurement Gap and the SL Gap to the UE, the measurement Gap and the SL Gap The relative priority between them is used to instruct the UE to select the measurement Gap or the SL Gap.

Specifically, the base station and the UE have agreed on whether the base station delivers the high-priority Gap or the low-priority Gap. After that, the base station only needs to deliver the measurement Gap or SL Gap to the UE, and the UE can clearly measure the gap between the Gap and the SL Gap. relative priority between. For example, the base station and the UE have agreed that the base station sends the high-priority Gap, then when the base station sends the measurement gap, the UE determines that the measurement gap has a higher priority than the SL Gap; when the base station sends the SL Gap, The UE determines that the SL Gap has a high priority over the measurement Gap. Alternatively, the base station configures priority values for the measurement Gap and the SL Gap respectively, and the UE compares the two values to determine the relative priority between the measurement Gap and the SL Gap. In this embodiment, the smaller the value, the higher the priority. Assuming that the value of the priority configured by the base station for measuring the Gap is 2, and the value of the priority configured for the SL Gap is 3, the UE can determine that the measurement Gap is relative to the SL Gap is high priority. Certainly, the base station may also deliver the relative priority between the measurement Gap and the SLGap in other manners, which is not limited in this embodiment.

Optionally, the base station may add the relative priority between the measurement Gap and the SL Gap to the configuration information in step 302 and send it to the UE, so as to save the base station from sending the relative priority between the measurement Gap and the SL Gap through additional configuration information. Signaling wasted by priority.

Step 307 , when the measurement Gap has a higher priority than the SL Gap, the UE selects the measurement Gap, and performs step 308 .

When the measurement Gap has a higher priority than the SL Gap, it indicates that the importance of performing the neighbor cell measurement is higher than the importance of transmitting data packets on the SL, and at this time, the UE selects the measurement Gap.

Step 308, the UE performs neighbor cell measurement in the measurement gap, and the process ends.

Step 309, when the measurement Gap has a lower priority than the SL Gap, the UE selects the SL Gap.

When the measurement Gap has a lower priority than the SL Gap, it indicates that the importance of performing the neighbor measurement is lower than the importance of transmitting data packets on the SL, and the UE selects the SL Gap at this time.

Step 310, the UE transmits data packets in the SL Gap.

To sum up, in the Gap selection method provided by the embodiment of the present invention, when the measurement Gap conflicts with the SL Gap, one of the measurement Gap and the SL Gap is selected; when the measurement Gap is selected, the neighbor cell is selected in the measurement Gap. measurement; or, when the SL Gap is selected, the data packets are transmitted in the SL Gap, so that when the measurement gap and the SL Gap conflict, the UE can still perform neighbor cell measurement in the measurement gap or transmit data packets in the SL Gap, without having to Configure the measurement gap and SLGap that are completely staggered from each other, thus solving the problem of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

In addition, by selecting the measurement Gap or the SL Gap according to the relative priority between the measurement Gap and the SL Gap, the measurement Gap can be selected when the measurement Gap has a high priority relative to the SL Gap; when the measurement Gap has a low priority relative to the SL Gap When the SL Gap is selected, the Gap selected by the UE meets the actual requirements and the accuracy of Gap selection is improved.

Please refer to FIG. 4 , which shows a method flowchart of another Gap selection method provided by an embodiment of the present invention. In this embodiment, the UE selects to measure the Gap or the SL Gap according to the signal parameters of the UE's serving cell. The Gap selection method can include:

Step 401, the base station determines the measurement gap configured for the UE.

Step 402, the base station generates configuration information, where the configuration information is used to indicate the time when the measurement gap occurs.

Step 403, the base station sends the configuration information to the UE.

Step 404, the UE receives the configuration information sent by the base station.

Step 405, the UE judges whether the measurement gap conflicts with the SL gap according to the time when the measurement gap appears and the time when the SL gap appears, and the time when the SL gap appears is configured according to a predetermined policy.

The implementation process of steps 401-405 is detailed in the description in steps 301-305, which is not repeated here.

Step 406, when the measurement Gap conflicts with the SL Gap, the UE acquires the signal parameters of the serving cell of the UE, and the signal parameters are signal strength or signal quality.

In this embodiment, whether the signal parameter is signal strength or signal quality may be pre-agreed by the base station and the UE. The signal strength and signal quality are used to indicate the quality of the signal of the serving cell. The technology for the UE to acquire the signal strength or the signal quality is very mature, and details are not described in this embodiment.

Step 407, the UE compares the signal parameters with the signal threshold, the signal threshold is delivered by the base station, or the signal threshold is determined by the UE.

The signal threshold value is related to the signal parameter obtained by the UE. For example, when the signal parameter obtained by the UE is the signal strength, the signal threshold value is the signal strength threshold value; when the signal parameter obtained by the UE is the signal quality, the signal threshold value is the signal quality threshold value.

In a possible implementation manner, the base station sends the signal threshold value; in another possible implementation manner, the UE determines the signal threshold value. Wherein, when the UE determines the signal threshold value, the UE may read the signal threshold value specified in the communication protocol; or, the UE may determine the signal threshold value by itself. When the UE itself determines the signal threshold value, the UE may notify the base station of the signal threshold value, or may not notify the base station, which is not limited in this embodiment.

When the base station sends the signal threshold value, the method provided in this embodiment further includes: the base station sends the signal threshold value to the UE, where the signal threshold value is used to instruct the UE to select the measurement Gap or the SL Gap.

Optionally, the base station may add the signal threshold value to the configuration information in step 402 and send it to the UE, so as to save the signaling wasted by the base station in sending the signal threshold value through additional configuration information.

It should be supplemented that the UE can also obtain the signal strength and signal quality of the serving cell at the same time. The signal threshold at this time includes the signal strength threshold and the signal quality threshold. The UE needs to compare the signal strength with the signal strength threshold. value and compare the signal quality to the signal quality threshold value. In a possible implementation manner, when the signal strength is greater than the signal strength threshold value or the signal quality is greater than the signal quality threshold value, it is determined that the signal parameter is greater than the signal threshold value; when the signal strength is less than the signal strength threshold value and the signal quality is greater than the signal strength threshold When it is less than the signal quality threshold value, it is determined that the signal parameter is less than the signal threshold value. In another possible implementation manner, when the signal strength is greater than the signal strength threshold value and the signal quality is greater than the signal quality threshold value, it is determined that the signal parameter is greater than the signal threshold value; when the signal strength is less than the signal strength threshold value or the signal strength When the quality is less than the signal quality threshold value, it is determined that the signal parameter is less than the signal threshold value.

Step 408 , when the signal parameter is less than the signal threshold, the UE selects to measure the Gap, and executes step 409 .

When the signal parameter is less than the signal threshold, it indicates that the signal of the serving cell at this time is poor, and the UE prioritizes neighbor cell measurement, so that when the signal of the neighbor cell is good, the neighbor cell is switched to the UE's serving cell in time to ensure that The normal communication of the UE.

Step 409, the UE performs neighbor cell measurement in the measurement gap, and the process ends.

Step 410, when the signal parameter is greater than the signal threshold, the UE selects the SL Gap.

When the signal parameter is greater than the signal threshold, it indicates that the serving cell signal is better at this time, and the UE does not need to perform neighbor cell measurement first.

Step 411, the UE transmits data packets in the SL Gap.

To sum up, in the Gap selection method provided by the embodiment of the present invention, when the measurement Gap conflicts with the SL Gap, one of the measurement Gap and the SL Gap is selected; when the measurement Gap is selected, the neighbor cell is selected in the measurement Gap. measurement; or, when the SL Gap is selected, the data packets are transmitted in the SL Gap, so that when the measurement gap and the SL Gap conflict, the UE can still perform neighbor cell measurement in the measurement gap or transmit data packets in the SL Gap, without having to Configure the measurement gap and SLGap that are completely staggered from each other, thus solving the problem of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

In addition, by selecting the measurement Gap or SL Gap according to the signal parameters of the serving cell of the UE, when the signal of the serving cell is poor, the measurement Gap can be selected to give priority to the neighboring cell measurement, and when the signal of the neighboring cell is good, timely The neighboring cell is switched to the serving cell of the UE to ensure the normal communication of the UE.

Please refer to FIG. 5 , which shows a method flowchart of another Gap selection method provided by an embodiment of the present invention. In this embodiment, the UE selects the measurement Gap or the SL Gap according to the priority of the data packet. The Gap selection method can include:

Step 501, the base station determines the measurement gap configured for the UE.

Step 502, the base station generates configuration information, where the configuration information is used to indicate the time when the measurement gap occurs.

Step 503, the base station sends the configuration information to the UE.

Step 504, the UE receives the configuration information sent by the base station.

Step 505, the UE judges whether the measurement gap conflicts with the SL gap according to the time when the measurement gap appears and the time when the SL gap appears, and the time when the SL gap appears is configured according to a predetermined policy.

The implementation process of steps 501-505 is detailed in the descriptions in steps 301-305, which will not be repeated here.

Step 506, when the measurement Gap conflicts with the SL Gap, the UE obtains the priority of the data packet.

The data packet refers to the data packet to be transmitted on the SL through the SL Gap. The priority of the data packet may be represented by a numerical value, for example, the numerical value of the priority of the data packet is 1, or the numerical value of the priority of the data packet is 4, etc., which is not limited in this embodiment. Among them, the technology for the UE to obtain the priority of the data packet is very mature, which will not be repeated in this embodiment.

Step 507, the UE compares the priority of the data packet with the data packet priority threshold value, the data packet priority threshold value is delivered by the base station, or the data packet priority threshold value is determined by the UE.

In a possible implementation manner, the base station issues the data packet priority threshold value; in another possible implementation manner, the UE determines the data packet priority threshold value. Wherein, when the UE determines the data packet priority threshold, the UE may read the data packet priority threshold specified in the communication protocol; or, the UE may determine the data packet priority threshold by itself. When the UE itself determines the data packet priority threshold, the UE may notify the base station of the data packet priority threshold, or may not notify the base station, which is not limited in this embodiment.

When the base station delivers the data packet priority threshold, the method provided in this embodiment further includes: the base station sends the data packet priority threshold to the UE, where the data packet priority threshold is used to instruct the UE to select a measurement Gap or SL Gap.

Optionally, the base station may add the data packet priority threshold value to the configuration information in step 502 and send it to the UE, so as to save the signaling wasted by the base station sending the data packet priority threshold value through additional configuration information.

It is assumed that the smaller the value, the higher the priority, and the value of the priority of the data packet is 2, and the priority value of the data packet is 3, then the priority of the data packet is higher than the priority value of the data packet; If the priority threshold value is 1, the priority of the data packet is lower than the data packet priority threshold value.

Step 508 , when the priority of the data packet is lower than the data packet priority threshold, the UE selects to measure the Gap, and performs step 509 .

When the priority of the data packet is lower than the data packet priority threshold value, it indicates that the data packet that needs to be transmitted on the SL is not very urgent, and the UE preferentially chooses to measure the Gap.

Step 509, the UE performs neighbor cell measurement in the measurement gap, and the process ends.

Step 510, when the priority of the data packet is higher than the data packet priority threshold, the UE selects the SL Gap.

When the priority of the data packet is higher than the data packet priority threshold value, it indicates that the data packet that needs to be transmitted on the SL is very urgent, and the UE preferentially selects the SL Gap.

Step 511, the UE transmits data packets in the SL Gap.

To sum up, in the Gap selection method provided by the embodiment of the present invention, when the measurement Gap conflicts with the SL Gap, one of the measurement Gap and the SL Gap is selected; when the measurement Gap is selected, the neighbor cell is selected in the measurement Gap. measurement; or, when the SL Gap is selected, the data packets are transmitted in the SL Gap, so that when the measurement gap and the SL Gap conflict, the UE can still perform neighbor cell measurement in the measurement gap or transmit data packets in the SL Gap, without having to Configure the measurement gap and SLGap that are completely staggered from each other, thus solving the problem of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

In addition, by selecting the measurement Gap or the SL Gap according to the priority of the data packet, it can be determined that the data packet to be transmitted on the SL through the SL Gap is urgent when the priority of the data packet is higher than the data packet priority threshold. At this time, SL Gap is preferred to ensure the normal operation of the business.

Please refer to FIG. 6 , which shows a method flowchart of another Gap selection method provided by an embodiment of the present invention. In this embodiment, the UE selects a service according to whether the data packet belongs to public safety (English: Public Safety; abbreviated as: PS) Measurement Measurement Gap or SL Gap. The Gap selection method can include:

Step 601, the base station determines the measurement gap configured for the UE.

Step 602, the base station generates configuration information, where the configuration information is used to indicate the time when the measurement gap occurs.

Step 603, the base station sends the configuration information to the UE.

Step 604, the UE receives the configuration information sent by the base station.

Step 605, the UE judges whether the measurement gap conflicts with the SL gap according to the time when the measurement gap appears and the time when the SL gap appears, and the time when the SL gap appears is configured according to a predetermined policy.

The implementation process of steps 601-605 is detailed in the descriptions in steps 301-305, which are not repeated here.

Step 606, when the measurement Gap collides with the SL Gap, the UE determines whether the data packet belongs to the PS service.

Among them, PS business refers to the business involving public safety. For example, PS services include military communication services; non-PS services include civilian or commercial communication services.

When determining whether the data packet belongs to the PS service, in a possible implementation manner, the UE determines whether the data packet belongs to the PS service according to its own attributes. For example, when the UE is a military walkie-talkie, all data packets transmitted by the UE are Belong to PS business. In another possible implementation manner, the UE determines whether the data packet belongs to the PS service according to the attribute of the data packet. For example, the UE reads the destination Internet address (English: Internet Protocol; IP) and destination port of the data packet, Detect whether the destination IP address and destination port are the destination IP address and destination port used in the PS service, and when the destination IP address and destination port are the destination IP address and destination port used in the PS service, determine that the data packet belongs to the PS service; When the destination IP address and destination port are not the destination IP and destination port used in the PS service, it is determined that the data packet does not belong to the PS service. Of course, the UE may also determine whether the data packet belongs to the PS service in other ways, which is not limited in this embodiment.

Step 607, when the data packet does not belong to the PS service, the UE selects to measure the Gap, and executes step 608.

When the data packet does not belong to the PS service, it indicates that the data packet that needs to be transmitted on the SL is not very urgent, and the UE preferentially chooses to measure the Gap.

Step 608, the UE performs neighbor cell measurement in the measurement gap, and the process ends.

Step 609, when the data packet belongs to the PS service, the UE selects the SL Gap.

When the data packet belongs to the PS service, it indicates that the data packet that needs to be transmitted on the SL is urgent, and the UE preferentially selects SLGap.

Step 610, the UE transmits data packets in the SL Gap.

To sum up, in the Gap selection method provided by the embodiment of the present invention, when the measurement Gap conflicts with the SL Gap, one of the measurement Gap and the SL Gap is selected; when the measurement Gap is selected, the neighbor cell is selected in the measurement Gap. measurement; or, when the SL Gap is selected, the data packets are transmitted in the SL Gap, so that when the measurement gap and the SL Gap conflict, the UE can still perform neighbor cell measurement in the measurement gap or transmit data packets in the SL Gap, without having to In order to configure the measurement gap and SL gap that are completely staggered from each other, it solves the problem of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

In addition, by selecting the measurement Gap or SL Gap according to whether the data packet to be transmitted in the SL Gap belongs to the PS service, it can be determined that the data packet to be transmitted on the SL through the SL Gap is urgent when the data packet belongs to the PS service. SL Gap is preferred to ensure the normal operation of the business.

Please refer to FIG. 7 , which shows a method flowchart of another Gap selection method provided by an embodiment of the present invention. In this embodiment, the UE selects and measures the Gap according to whether the frequency where the neighbor cell is located belongs to a reduced performance group. Or SL Gap. The Gap selection method can include:

Step 701, the base station determines the measurement gap configured for the UE.

Step 702, the base station generates configuration information, where the configuration information is used to indicate the time when the measurement gap occurs.

Step 703, the base station sends the configuration information to the UE.

Step 704, the UE receives the configuration information sent by the base station.

Step 705, the UE determines whether the measurement gap conflicts with the SL gap according to the time when the measurement gap appears and the time when the SL gap appears, and the time when the SL gap appears is configured according to a predetermined policy.

The implementation process of steps 701-705 is detailed in the description in steps 301-305, which is not repeated here.

Step 706, when the measurement Gap conflicts with the SL Gap, the UE determines whether the frequency where the adjacent cell is located belongs to the reduction performance group, the reduction performance group is a frequency group with the worst delay performance in each frequency group, and the frequency group is required for the UE. The measured frequencies are grouped.

Measurements made on frequencies in the muting performance group are generally not measurements that serve mobility. For example, the frequencies in the shedding capability group are measured to find cells to be offloaded or to find accessible APs, and so on. Since the measurement of the frequencies in the abatement performance group is not used to find handover neighbor cells, it is generally not very urgent to measure the frequencies in the abatement performance group. Choose to measure Gap or SLGap.

Usually, the base station delivers measurement configuration information to the UE, the measurement configuration information includes at least one measurement frequency, and each measurement frequency belongs to one of two frequency groups, and one of the two frequency groups is a performance reduction group , and the other is the normal performance group. In specific implementation, the UE may first determine the frequency of the adjacent cell to be measured in the measurement gap, and then determine the frequency group to which the frequency belongs, and determine whether the frequency of the adjacent cell belongs to the reduction performance group according to the frequency group to which it belongs.

Step 707, when the frequency does not belong to the reduction performance group, the UE selects to measure the Gap, and performs step 708.

When the frequency where the neighbor cell is located does not belong to the reduced performance group, it indicates that the UE may search for a handover neighbor cell through neighbor cell measurement, and the signal quality of the serving cell may be poor. When the signal of the neighboring cell is good, the neighboring cell is switched to the serving cell of the UE in time to ensure the normal communication of the UE.

Step 708, the UE performs neighbor cell measurement in the measurement gap, and the process ends.

Step 709, when the frequency where the neighbor cell is located belongs to the reduction performance group, the UE selects the SL Gap.

When the frequency where the adjacent cell is located belongs to the reduction performance group, it indicates that the measurement of the adjacent cell is not very urgent, and the UE selects SL Gap at this time.

Step 710, the UE transmits data packets in the SL Gap.

To sum up, in the Gap selection method provided by the embodiment of the present invention, when the measurement Gap conflicts with the SL Gap, one of the measurement Gap and the SL Gap is selected; when the measurement Gap is selected, the neighbor cell is selected in the measurement Gap. measurement; or, when the SL Gap is selected, the data packets are transmitted in the SL Gap, so that when the measurement gap and the SL Gap conflict, the UE can still perform neighbor cell measurement in the measurement gap or transmit data packets in the SL Gap, without having to Configure the measurement gap and SLGap that are completely staggered from each other, thus solving the problem of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

In addition, by selecting the measurement Gap or SL Gap according to whether the frequency where the neighbor cell is located belongs to the reduction performance group, it can be determined that the UE may search for a handover neighbor cell through the neighbor cell measurement when the frequency where the neighbor cell is located does not belong to the reduction performance group. , the signal quality of the serving cell may be poor at this time, and the UE preferentially selects the measurement gap to measure the neighboring cells, so that when the signal of the neighboring cell is good, the neighboring cell is switched to the serving cell of the UE in time to ensure the normal communication of the UE.

Please refer to FIG. 8 , which shows a method flowchart of another Gap selection method provided by an embodiment of the present invention. In this embodiment, the UE selects to measure the Gap or SL Gap. The Gap selection method can include:

Step 801, the base station determines the measurement gap configured for the UE.

Step 802, the base station generates configuration information, where the configuration information is used to indicate the time when the measurement gap occurs.

Step 803, the base station sends the configuration information to the UE.

Step 804, the UE receives the configuration information sent by the base station.

Step 805, the UE judges whether the measurement gap conflicts with the SL gap according to the time when the measurement gap appears and the time when the SL gap appears, and the time when the SL gap appears is configured according to a predetermined policy.

The implementation process of steps 801-805 is detailed in the description in steps 301-305, which is not repeated here.

Step 806, when the measurement Gap conflicts with the SL Gap, the UE determines whether the SL Gap is used to receive data packets or to send data packets, whether the SL Gap is used to receive data packets or to send data packets is indicated by the base station, or, Whether the SL Gap is used to receive data packets or to send data packets is determined by the UE.

In a possible implementation, the base station indicates whether the SL Gap is used to receive data packets or to send data packets; in another possible implementation, the UE decides whether the SL Gap is used to receive data packets or use to send packets. Wherein, when the UE decides whether the SL Gap is used to receive data packets or to send data packets, the UE can read whether the SL Gap specified in the communication protocol is used to receive data packets or to send data packets; or, the UE can It decides by itself whether the SL Gap is used to receive packets or to send packets. When the UE itself decides whether the SL Gap is used to receive data packets or to send data packets, the UE can notify the base station whether the SL Gap is used to receive data packets or send data packets, or not notify the base station. limited.

When the base station indicates whether the SL Gap is used to receive data packets or to send data packets, the method provided by this embodiment further includes: the base station indicates to the UE whether the SL Gap is used to receive data packets or to send data packets, and the SL Gap is used to receive data packets or to send data packets. Whether Gap is used to receive data packets or to send data packets is used to instruct the UE to choose to measure Gap or SL Gap.

Optionally, the base station can use the configuration information in step 802 to indicate whether the SL Gap is used to receive data packets or to send data packets, so as to save the base station from indicating whether the SL Gap is used to receive data packets or send data packets through additional configuration information. Signaling wasted by packets.

In this embodiment, the UE can choose to measure the gap when the SL Gap is used to receive data packets, and choose the SL Gap when the SL Gap is used to send data packets; the UE can also choose to measure the gap when the SL Gap is used to send data packets. SL Gap is used to select SL Gap when receiving data packets. In a possible implementation manner, the base station issues the above selection rule; in another possible implementation manner, the UE decides the above selection rule. Wherein, when the UE determines the above selection rule, the UE may read the above selection rule specified in the communication protocol; or, the UE may decide the above selection rule by itself. When the UE itself decides the above selection rule, the UE may notify the base station of the above selection rule, or may not notify the base station, which is not limited in this embodiment.

When multiple UEs communicate with each other on the SL at the same time, since only one UE can send data packets at the same time and other UEs can receive data packets, the time for each UE to send data packets is much shorter than the time for receiving data packets , therefore, the importance of sending data packets is higher than that of receiving data packets. Ensure the normal sending of data packets.

Among them, in order to facilitate the understanding of the duration of sending data packets and the duration of receiving data packets, this embodiment is described by taking 10 minutes of SL communication between five UEs as an example, and the duration of each UE sending data packets is 2 minutes. The time to receive a packet is 8 minutes.

Step 807 , when the SL Gap is used to receive data packets, the UE selects the measurement gap, and performs step 808 .

Step 808, the UE performs neighbor cell measurement in the measurement gap, and the process ends.

Step 809, when the SL Gap is used to send data packets, the UE selects the SL Gap.

Step 810, the UE transmits data packets in the SL Gap.

To sum up, in the Gap selection method provided by the embodiment of the present invention, when the measurement Gap conflicts with the SL Gap, one of the measurement Gap and the SL Gap is selected; when the measurement Gap is selected, the neighbor cell is selected in the measurement Gap. measurement; or, when the SL Gap is selected, the data packets are transmitted in the SL Gap, so that when the measurement gap and the SL Gap conflict, the UE can still perform neighbor cell measurement in the measurement gap or transmit data packets in the SL Gap, without having to Configure the measurement gap and SLGap that are completely staggered from each other, thus solving the problem of configuring the measurement gap and SL gap that are completely staggered from each other, which leads to the difficulty of configuring the gap and the low configuration efficiency, and achieves the effect of improving the efficiency of configuring the gap.

In addition, by selecting the measurement Gap or SL Gap according to whether the SL Gap is used to receive or send data packets, the SL Gap can be selected when the SL Gap is used to send data packets, because the importance of sending data packets is higher than that of receiving data packets. The importance of the data packet, therefore, the UE preferentially selects the SL Gap to send the data packet to ensure the normal transmission of the data packet.
