Description

Pilot frequency measurement time delay determination method, device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, and a storage medium for determining inter-frequency measurement delay.

Background

In a Long Term Evolution (LTE) system and a new radio access technology (NR), inter-frequency measurement is a measurement form used by a terminal device to determine channel quality between the terminal device and each cell. For inter-frequency measurement, there are two factors that affect the delay index: the measurement time delay of a single frequency point and the number of different frequency points which are configured for the terminal equipment by the network equipment and need to be measured. Because the measurement delay of a single frequency point is equal to the product of the number of measurement resources and the time required for obtaining one measurement opportunity, the measurement delay of a plurality of frequency points is equal to the product of the measurement delay of a single frequency point and a frequency point number scaling factor, wherein the frequency point number scaling factor is the multiple of the amplification required by the multi-frequency point measurement delay relative to the single-frequency point measurement delay when a plurality of frequency points configured in a network are simultaneously measured. Therefore, for the delay index of pilot frequency measurement, the frequency point number scaling factor is a key parameter.

At present, in the existing LTE system, the number of pilot frequency/pilot system frequency points configured for the terminal device by the network device can be directly used as the measurement delay scaling factor. Specifically, the network device is the number N of pilot frequency/pilot system frequency points configured for the terminal device_freqCan be expressed by the following formula:

N_freq＝N_{freq，E-UTRA}+N_freq，UTRA+N_freq，gsm+N_{freq，CDMA2000}+N_freq，HRPD+N_freq，NR

wherein:

N_{freq，E-UTRA}the LTE frequency point number configured for the terminal device for the network device includes frequency points in two modes, Time Division Duplex (TDD) and Frequency Division Duplex (FDD);

N_freq，UTRAa third generation partnership project (3 GPP)3G system frequency point number configured for the network device to the terminal device, including wideband code division multiple access (W-CDMA) or time division-synchronous code division multiple access (TD-SCDMA);

N_freq，gsmthe number of frequency points of a global system for mobile communication (GSM) configured for the terminal equipment for the network equipment;

N_{freq，CDMA2000}CDMA2000 frequency for network equipment and terminal equipment configurationCounting;

N_freq，HRPDa High Rate Packet Data (HRPD) network frequency point number configured for the network device to the terminal device;

N_freq，NRand configuring the number of NR frequency points for the network equipment to the terminal equipment.

Therefore, in LTE, the multi-frequency measurement delay of inter-frequency measurement can be scaled as:

multiple frequency point measuring time delay (measuring time delay multiplied by N) of single frequency point_freq

However, in the NR system, the network device configures at most one synchronization signal block-based measurement timing configuration (SMTC) for each pilot frequency point, and the configuration of the SMTC at least includes three parameters, namely, an SMTC window period, an SMTC window offset, and an SMTC window length, and each parameter may have a different value, so that measurement resources of all frequency points are not overlapped in time at the same time, and thus, the measurement delay scaling factor determined by the above method is not fair for a part of the frequency points where the measurement resources in the multiple frequency points are not overlapped in time.

For example, the terminal device 12 may also serve as a sender, the network device 11 serves as a receiver, and the terminal device 12 transmits information to the network device 11 through a transmission beam.

The system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

For convenience of description, in all embodiments of the present application, the above-mentioned apparatus for providing a wireless communication function for a terminal device is collectively referred to as a network device.

That is, the terminal device may also be referred to as a User Equipment (UE), a Mobile Station (MS), a mobile terminal (mobile terminal), a terminal (terminal), and the like, and the terminal device may communicate with one or more core networks via a Radio Access Network (RAN), for example, the terminal device may be a mobile phone (or a "cellular" phone), a computer with a mobile terminal, and the like, for example, the terminal device may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges language and/or data with the RAN, which is not specifically limited in this embodiment.

In the embodiments of the present application, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

For example, before briefly introducing an applicable scenario of the present embodiment, some terms involved in the embodiments of the present application are first explained:

and (3) pilot frequency measurement: in a new radio access technology (NR), measurement based on a Synchronization Signal Block (SSB) can be divided into two types, namely co-frequency measurement and inter-frequency measurement, and if the SSB of a target cell and the SSB of a serving cell of a terminal device have the same center frequency and subcarrier spacing, the measurement of the SSB is the co-frequency measurement, otherwise, the measurement is the inter-frequency measurement.

First, a brief description is given of an application scenario of the embodiment of the present application.

At present, in LTE and NR, cell reselection (reselection) and handover (handover) are two indispensable functions in order to ensure channel quality between the terminal device and the serving cell. In order to support cell reselection and handover, the terminal device needs to continuously perform mobility measurement to determine channel quality between the terminal device and each cell.

Illustratively, according to whether the frequency point measured by the terminal device, the frequency relationship of the serving cell and the access technology are the same, the mobility measurement can be divided into intra-frequency measurement (intra-frequency measurement), inter-frequency measurement (inter-frequency measurement) and inter-system measurement.

Currently, in order to clarify the behavior of the terminal device and ensure the performance of the measurement, the 3GPP specifies the delay index and the performance index of the measurement. For pilot frequency measurement, there are two factors that affect the delay index: the measurement time delay of a single frequency point and the number of pilot frequency points which are configured for the terminal equipment by the network and need to be measured. These two factors are first briefly explained below:

measurement time delay of a single frequency point:

the measurement delay of a single frequency point refers to the time required for meeting performance indexes (such as measurement accuracy) when pilot frequency measurement is carried out on one pilot frequency point. Generally, the time required for a terminal device to obtain a measurement occasion (measurement occasion) is related to the transmission cycle of measurement resources on the frequency point, the cycle of a measurement interval (MG), and the length of a Discontinuous Reception (DRX) cycle. In addition, according to the current channel condition, the terminal device may need to measure a plurality of measurement resources, filter the measurement result of each measurement resource, and use the filtered result as the final measurement result to enable the measurement accuracy to meet the requirement. Therefore, the measurement delay of a single frequency point can be represented by the following form: the measurement time delay of a single frequency point is the number of measurement resources multiplied by the time required for acquiring a measurement opportunity.

The number of the pilot frequency points which are configured for the terminal equipment by the network and need to be measured is as follows:

in practical applications, since measurement resources used for measurement at different frequency points may overlap in time, at this time, if a terminal device wants to measure multiple frequency points simultaneously, the terminal device needs to be configured with multiple measurement modules. However, in practice, due to the consideration of cost control, the number of measurement modules configured in the terminal device is limited, which means that different frequency points can only be performed in a time division manner, only a plurality of frequency points in all configured frequency points are measured in each period of measurement resources, and the rest frequency points are left in the following period for measurement. In this case, the delay index of the inter-frequency measurement needs to be extended accordingly according to the number of frequency points configured for the terminal device by the network. In the embodiment of the application, when a plurality of frequency points configured by a network are measured simultaneously, the measurement delay scaling factor is used to indicate the multiple of amplification required by the multi-frequency point measurement delay relative to the single-frequency point measurement delay. Namely, the method comprises the following steps: the multi-frequency point measurement time delay is the measurement time delay of a single frequency point multiplied by a measurement time delay scaling factor.

It can be seen that the measurement delay scaling factor is a very important parameter for determining the delay index of the inter-frequency measurement.

For example, as can be seen from the background art of the embodiment of the present application, in an existing LTE system, the number of pilot/pilot system frequency points configured by a network device for a terminal device may be directly used as a measurement delay scaling factor, which is suitable for the LTE system, because the period of a synchronization signal in the LTE system is fixed, for example, 5ms, and therefore, in any 5ms interval, measurement resources used for measurement at each pilot frequency point are always overlapped.

However, it is not suitable for NR to directly use the number of pilot/pilot system frequency points configured for the terminal device by the network device as the measurement delay scaling factor. This is because in NR, the network configures at most one synchronization signal block-based measurement timing configuration (SMTC) for each pilot frequency, which actually indicates an available measurement window for the terminal device. The network device ensures that the terminal device can search a Synchronization Signal Block (SSB) sent by each cell on the frequency point in the available measurement window through configuration on the network side. Specifically, the configuration of the SMTC includes three parameters: SMTC window period, SMTC window offset, and SMTC window length.

Wherein, SMTC window period: i.e. the time interval between two adjacent occurrences of the SMTC window. Illustratively, the value may be 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, or the like;

SMTC window offset: i.e., the starting position of the SMTC window within one cycle. Illustratively, the value may be 0ms, 1ms, …, (SMTC window period-1) ms, and the like.

SMTC window length: i.e., the duration of the SMTC window. Exemplary, possible values are 1ms, 2ms, 3ms, 4ms or 5 ms.

Therefore, each parameter included in the configuration of the SMTC may have a different value, that is, the configuration of the synchronization signal in the NR is more flexible than that in the LTE system, which results in that measurement resources of all frequency points are not overlapped in time at the same time, and thus, the measurement delay scaling factor determined by the above method is unfair for each frequency point. The following description will be made by taking fig. 2 as an example.

Fig. 2 is a distribution diagram of configurations of SMTCs in NRs. Fig. 2 exemplarily shows the SMTC window period and the SMTC window offset of four frequency points, i.e., frequency point 1, frequency point 2, frequency point 3, and frequency point 4, and the SMTC window lengths are the same in fig. 2. As shown in fig. 2, among the four frequency bins shown in fig. 2, the SMTC window period of frequency bin 2 is the shortest and thus has the most measurement opportunities, while the SMTC window period of frequency bin 1 is the longest and thus has the least measurement opportunities.

In addition, although frequency point 3 and frequency point 4 have the same SMTC window period, the SMTC window offset is different, and the two have different measurement timings. This is because the first SMTC window at bin 3 in every 160ms overlaps with the first SMTC window at bin 1 and bin 2 in every 160ms, so the measurement opportunity on the first SMTC window in every 160ms must be shared among three bins, while each SMTC window at bin 4 in every 160ms overlaps with the first SMTC window at bin 2 in every 160ms, so the measurement opportunity on the second SMTC window and the fourth SMTC window in every 160ms only needs to be shared among these two bins. However, in the prior art, directly using the number of frequency points as the measurement delay scaling factor means that the frequency point 3 and the frequency point 4 use the same delay index, so the measurement delay scaling factor determined by the method is unfair for the frequency point 3.

For example, the overlapping in the embodiment of the present application may mean that the time domain ranges of the SMTC windows of the frequency points intersect.

In summary, the drawback of the prior art is that the design of the synchronization signal in NR changes compared to LTE, so that the weighting method in LTE cannot be directly applied, and the measurement delay scaling factor of each frequency point should be determined in consideration of the overlapping degree of the measurement opportunities of the frequency point and other frequency points, so that the measurement opportunities of each frequency point can be fair.

The embodiment of the application provides a method for determining different-frequency measurement time delay aiming at the problem that the measurement time of each frequency point in NR is not fair due to the determined measurement time delay scaling factor in the prior art, and the method determines the measurement time delay scaling factor of the frequency point by calculating the ratio of the time required by obtaining one-time measurement time under the condition of multiple frequency points and the time required by obtaining one-time measurement time under the condition of single frequency points, so that the problem that the measurement time of each frequency point in NR is not fair is avoided.

Before describing the specific embodiments of the present application, it is noted that, first, several constraints are imposed on the values of the parameters in the configuration of the SMTC according to the specifications in 3GPP to simplify the description. In 3GPP there are the following specifications: if the capability of the terminal device does not support the terminal device to perform the inter-frequency measurement when the network does not configure a measurement interval (MG) for the terminal device, the network does not expect the terminal device to perform the inter-frequency measurement beyond the effective measurement time of the MG. Thus, any SMTC window that does not overlap in time with the MG is not available. The following is a description with reference to a schematic diagram shown in fig. 3.

FIG. 3 is a schematic diagram of the constraint relationship between MG and SMTC windows. As shown in fig. 3, the SMTC window period of the frequency point 1 and the frequency point 2 is greater than the measurement interval repetition period (MGRP), and the SMTC window period of the frequency point 3 is smaller than the MGRP. Therefore, as shown in fig. 3, some SMTC windows in all SMTC windows in frequency bin 3 fall outside the MG, and are not available. Therefore, for each frequency point, the SMTC window overlapping with the MG in time in the SMTC window of the frequency point is defined as an available measurement window of the frequency point, and an available measurement window period of the frequency point may be expressed as:

the available measurement window period is max (SMTC window period, MGRP) 20 · 2ⁱ

Wherein i is g, g +1, …, 3, g is 0, 1, 2 or 3. Wherein MGRP is 20.2^gIn ms. In NR, MGRP may take on values of 20ms, 40ms, 80ms or 160 ms.

For example, referring to fig. 3, according to the SMTC window periods and the SMTC window offsets of frequency point 1, frequency point 2 and frequency point 3 in the figure, the following conclusions can be drawn: any SMTC window that overlaps with a MG must have an offset that satisfies the following relationship:

SMTC Window offset + kXMGRP

Wherein k is 0, 1, …, 2^i-g-1. That is, the offset of the SMTC window is equal to the offset of MG plus a K integer multiple of MGRP.

For example, according to the existing conclusion of 3GPP, frequency points with the same available measurement window period and SMTC window offset should use the same delay index, so that all configured frequency points of the terminal device may be grouped according to the available measurement window period and the SMTC window offset.

Illustratively, all available measurement windows will be periodic by 20 · 2ⁱms, grouping the frequency points with the SMTC window offset of MG offset + k multiplied by MGRP into group (i, k), and recording the number of the frequency points in the group (i, k) as N_i，k. N within a group (i, k)_i，kThe frequency points should equally share the measurement opportunity.

For example, when i is equal to 0, g is equal to 0, and k is equal to 0, so the available measurement window period of a frequency point is 20ms, and the SMTC window offset is equal to the MG offset, so the available measurement window periods of all frequency points in group (0, 0) are 20ms, and the SMTC window offset is the MG offset; when i is 2, g is 1, k is 0 or 1, in this case, two frequency point groups group (2, 1) and group (2, 0) may be formed, where the available measurement window period of all frequency points in group (2, 1) is 80ms, and the SMTC window offset is MG offset + MGRP; the available measurement window period of all frequency points in group (2, 0) is 160ms, and the SMTC window offset is MG offset.

Illustratively, since the MGRP and the maximum value of the available measurement window period are both 160ms, the SMTC window and MGRP combination in any configuration will repeat after 160ms, and therefore, for the sake of simplifying the description, only the situation within 160ms needs to be considered in the embodiment of the present application. For example, fig. 4 is a schematic diagram illustrating the overlapping relationship between SMTC windows in each frequency bin group within 160 ms. The schematic diagram shown in fig. 4 is described by taking MGRP as 20ms as an example. As can be seen from fig. 4, for the tth SMTC window within 160ms of the group (i, k), the SMTC window temporally overlapped with the tth SMTC window is group (j, (t · 2)^i-g+k)mod2^j-g) To (1) a

An SMTC window where j is g, g +1, …, 3, so that each measurement time is shared between these bins.

Based on the above, the following description will discuss specific embodiments of the present application with reference to the drawings.

Fig. 5 is a schematic flowchart of a first embodiment of a method for determining inter-frequency measurement delay according to an embodiment of the present application. As shown in fig. 5, the method for determining inter-frequency measurement delay is applied to a terminal device, and the method may include the following steps:

step 51: and acquiring the number of measurement opportunities of the first frequency point group in a preset period.

The number of the measurement occasions may be the number of the measurement occasions in each available measurement window in the preset period.

The first group of frequency bins may be a set of multiple frequency bins having the same available measurement window period and synchronization signal block measurement timing configuration SMTC window offsets.

The preset period may be a maximum value among SMTC window period values.

The start time of the available measurement window is not earlier than the start time of the measurement interval MG plus the radio frequency switching time, and the end time of the available measurement window is not later than the end time of the MG minus the radio frequency switching time.

For example, in the embodiment of the present application, when multiple frequency points exist in a terminal device for simultaneous measurement, and a measurement delay of each frequency point needs to be determined, the terminal device may first determine a preset period to be measured and an available measurement window period in the preset period, where the preset period may select a maximum value among values of all SMTC window periods, then group all frequency points to be measured according to the available measurement window period of the frequency point and a size of an SMTC window offset, divide multiple frequency points having the same available measurement window period and a synchronization signal block measurement timing configuration SMTC window offset into one group, and obtain the number of measurement opportunities that each frequency point group may be divided into in the preset period again.

The available measurement window needs to satisfy the condition that the start time of the available measurement window is not earlier than the MG start time of the measurement interval plus the radio frequency switching time, and the end time of the available measurement window is not later than the MG end time minus the radio frequency switching time, and only if the available measurement window period satisfies the condition, the time in the available measurement window period can be equally divided into frequency points for use.

It should be noted that, in the embodiment of the present application, one of all frequency point groups is used for explanation, that is, the embodiment of the present application is used for explanation of the first frequency point group. It is to be understood that "first" and "second" in the embodiments of the present application do not indicate an order relationship, but merely indicate that the two are different. For example, the first frequency bin group and the second frequency bin group in the following embodiments represent two different frequency bin groups.

For example, the step 51 (obtaining the number of measurement occasions of the first frequency point packet in the preset period) in this embodiment may be implemented by at least any one of the following two possible implementation manners:

in a possible implementation manner of the present application, the method for determining inter-frequency measurement delay according to the embodiment of the present application may further include the following steps:

and receiving a configuration signaling sent by the network equipment, wherein the configuration instruction comprises measurement weights of each frequency point group measured on each available measurement window in the preset period.

For example, the network device may determine all frequency point groups and the measurement weight of each frequency point group when measuring on an available measurement window in a preset period in advance according to the available measurement window period and the SMTC window offset of each frequency point group, and then the network device may send the measurement weight of each frequency point group when measuring on each available measurement window in the preset period to the terminal device through the configuration instruction, so that the terminal device obtains the number of measurement occasions of each frequency point group in the preset period according to the content in the configuration instruction.

Correspondingly, after the terminal device receives the configuration instruction sent by the network device, the step 51 (obtaining the number of measurement occasions of the first frequency point packet in the preset period) may be specifically implemented as follows:

and acquiring the number of measurement opportunities of the first frequency point group in the preset period according to the measurement weight of each frequency point group measured on each available measurement window in the preset period.

For example, in an embodiment of the present application, after acquiring a configuration instruction sent by a network device, a terminal device may determine, according to an available measurement window period and an SMTC window offset of each frequency point group, a measurement opportunity number of each frequency point group in a preset period, and correspondingly, the terminal device may obtain, according to the available measurement window period and the SMTC window offset of a first frequency point group, the measurement opportunity number of the first frequency point group in the preset period.

The measurement opportunity number of the first frequency point group in the preset period determined in an interactive manner between the network device and the terminal device has higher accuracy, that is, when the measurement weight of a certain frequency point group measured on each available measurement window in the preset period changes, each measurement weight sent to the terminal device by the network device through the configuration instruction also changes, so that the measurement opportunity number of the first frequency point group obtained by the terminal device in the preset period has higher accuracy.

For example, in another possible implementation manner of the present application, the step 51 (obtaining the number of measurement occasions of the first frequency point group in the preset period) may specifically be implemented as follows:

step A1: and acquiring measurement weights of each frequency point group preset by the terminal equipment and the network equipment for measurement on each available measurement window in a preset measurement period.

For example, in the embodiment of the present application, before the terminal device calculates the measurement delay of each frequency point at multiple frequencies, the network device and the terminal device may pre-specify the delay index of each frequency point group and the measurement weight of each frequency point group measured on each available measurement window in a preset measurement period, and then when the terminal device calculates the measurement delay of each frequency point in each frequency point group, the measurement weight of each frequency point group measured on each available measurement window in the preset measurement period may be obtained according to the content preset with the network device.

It should be noted that the presetting in this embodiment may be preset by the network device and the terminal device before shipment, or may be protocol-specified and written in the terminal device and the network device, respectively. For the predefined content, the terminal device and the network device may directly obtain the content stored in the device itself, and the predefined specific meaning is not described herein again.

Step A2: and acquiring the number of measurement occasions of the first frequency point group in the preset period according to the measurement weight of each frequency point group measured on each available measurement window in the preset period.

For example, in an embodiment of the present application, after obtaining a measurement weight for each frequency point group to perform measurement on each available measurement window in a preset period, the terminal device determines, according to an available measurement window period of a first frequency point group and an SMTC window offset, a measurement opportunity number of the first frequency point group in the preset period.

Illustratively, by means of a method for predetermining the measurement weight of each frequency point group measured on each available measurement window in a preset period through network equipment and terminal equipment, the terminal equipment can determine the number of measurement occasions of the first frequency point group in the preset period without interacting with the network equipment, and the method is simple to implement and high in determination efficiency.

For example, in the embodiment of the present application, the number of measurement occasions of the first frequency point packet in the preset period refers to the number of times that the frequency point packet should be measured in the process of completing one round of measurement for all frequency point packets that overlap on a certain available measurement window.

For example, assume a grouping of frequency bins (i)₁，k₁) T th of (1)₁Available measurement windows and frequency point grouping (i)₂，k₂) T th of (1)₂The available measurement windows overlap in time and the frequency points are grouped into groups (i)₁，k₁) At the t th₁The number of frequency points on the available measurement window is

Frequency point grouping group (i)₂，k₂) At the t th₂The number of frequency points on the available measurement window is

This means that in the time of 1120ms for (3+4) × 160ms, there are 3 available measurement windows of 160ms for group (i)₁，k₁) For measurement of middle frequency point, there are 4 measurement windows available in 160ms for group (i)₂，k₂) And (5) measuring the intermediate frequency point.

Step 52: and determining the measurement time delay scaling factor of each frequency point in the first frequency point group according to the number of the measurement occasions of the first frequency point group in a preset period, the number of the plurality of frequency points in the first frequency point group and the available measurement window period of each frequency point in the first frequency point group.

For example, in the embodiment of the present application, according to the definition of the frequency point group, the terminal device may obtain an available measurement window period of each frequency point in each frequency point group, and then after determining each frequency point group, the terminal device may also obtain the number of the multiple frequency points included in each frequency point group.

Therefore, for the first frequency point grouping, the terminal device may determine the number of the multiple frequency points included in the first frequency point grouping and the available measurement window period of each frequency point in the first frequency point grouping, and after the terminal device determines the number of the measurement opportunities of the first frequency point grouping in the preset period, the measurement delay scaling factor of each frequency point in the first frequency point grouping may be calculated according to the determined number of the measurement opportunities of the first frequency point grouping in the preset period, the number of the multiple frequency points in the first frequency point grouping, and the available measurement window period of each frequency point in the first frequency point grouping.

Illustratively, the following explanation of the specific implementation of this step 52 in conjunction with a specific formula is provided.

In the embodiments of the present application, the first frequency bin group is represented by group (i, k), since the period of all available measurement windows of the first frequency bin group (i, k) is equal to 20 · 2ⁱms, and SMTC window offset is MG offset + k × MGRP. That is, the period of the available measurement window for all frequency points in the first frequency point group (i, k) is 20 · 2ⁱms, SMTC window offset MG offset + k MGRP. In this embodiment, the number of bins included in the first bin group is N_i，kAnd (4) showing. For the first frequency point grouping group (i, k), if the frequency point number N included in the first frequency point grouping_i,kWhen the measurement weight a is 0, the first frequency bin group (i, k) performs measurement in the tth available measurement window_i，k，t＝0。

For example, this step 52 (determining the measurement delay scaling factor of each frequency point in the first frequency point packet according to the number of measurement occasions of the first frequency point packet in the preset period, the number of the multiple frequency points in the first frequency point packet, and the available measurement window period of each frequency point in the first frequency point packet) can be implemented by the following steps B1 and B2:

step B1: according to the number of measurement opportunities of the first frequency point grouping in a preset period and the number of frequency points N in the first frequency point grouping group (i, k)_i，kDetermining the measurement times n of each frequency point in the first frequency point grouping group (i, k) obtained averagely in a preset period_i，k。

Wherein the number of measurement occasions is expressed by formula (1), and n is_i，kExpressed by equation (2):

wherein, a_i，k，tGrouping (i, k) for the first frequency point at the t-thThe measurement weights for measurements made over the measurement window are used,

The measurement weight measured on the available measurement window, the t-th available measurement window of the first frequency point grouping group (i, k) and the second frequency point grouping group (j, (t.2)^i-g+k)mod2^j-g) To (1) a

The available measurement windows overlap in time, i-g, g +1, …, 3, g-0, 1, 2, 3, k-0, 1, …, 2^i-g-1, j-g, g +1, …, 3, t is greater than or equal to 0 and less than or equal to 2^3-i-an integer of 1.

For example, in an embodiment of the present application, the number of measurement occasions of the first frequency point group (i, k) in the preset period may be obtained according to the measurement weight of the obtained first frequency point group (i, k) measured on the tth available measurement window and the measurement weights of all frequency point groups overlapped in time measured on the corresponding available measurement window, and is specifically obtained by calculation according to formula (1).

Illustratively, after determining the number of measurement occasions of the first frequency point group in the preset period, the number of frequency points N in the first frequency point group (i, k) is combined_i，kThe number of measurements n obtained by each frequency point in the first frequency point group (i, k) in the preset period can be obtained_i，kSpecifically, it is obtained according to the formula (2).

For example, in the embodiment of the present application, the second frequency point packet represents a frequency point packet whose available measurement window overlaps with the available measurement window of the first frequency point packet in terms of time, the number of the second frequency point packet may be one, two, or multiple, and it is determined according to an actual situation, and the application does not limit the number of the second frequency point packet.

Step B2: according to the measurement times n averagely obtained by each frequency point in the first frequency point grouping group (i, k) in a preset period_i，kDetermining the measurement time delay scaling factor K of each frequency point in the first frequency point grouping (i, K) according to the available measurement window period of each frequency point and the preset period_i，kSaid K is_i，kExpressed by equation (3):

wherein, K_i，kA measured delay scaling factor, n, for each frequency bin in a first frequency bin group (i, k)_i，kFor the number of measurements obtained by each frequency point in the first frequency point group (i, k) on average in a preset period, the available measurement window period is max (SMTC window period, measurement interval repetition period MGRP), the SMTC window period is the SMTC window period of each frequency point in the first frequency point group (i, k), and MGRP is 20 · 2^gAnd g is 0, 1, 2 or 3, the unit is ms, and the preset period is the maximum value in the SMTC window period value.

For example, in the embodiment of the present application, as can be known from the above description, an SMTC window period refers to a time interval between two adjacent occurrences of an SMTC window, and a measurement interval MG repeatedly occurs within a certain time, that is, a measurement interval repetition period (MGRP), and when an SMTC window of a frequency point in a frequency point group overlaps with an MG in time, an SMTC window period that can be utilized is an available measurement window period that is only referred to as the frequency point, so that the available measurement window period is max (SMTC window period, measurement interval repetition period MGRP).

When the measurement times n obtained by each frequency point in the first frequency point grouping group (i, k) in the preset period are determined_i，kAfter the available measurement window period of each frequency point and the preset period, the measurement delay scaling factor K of each frequency point in the first frequency point grouping group (i, K) can be determined according to the formula (3)_i，k。

Illustratively, in embodiments of the present application, the available measurement of frequency bins in a first frequency bin group (i, k)The measurement window period is 20.2ⁱms, the frequency points in the first frequency point group (i, k) have a measurement window period of 20 × 2 in the case of a single frequency point, where the preset period is 160msⁱObtaining a measurement opportunity within ms, wherein the available measurement window period is equal to 20 & 2ⁱms, the predetermined period is equal to 160ms, and the formula (4) can be obtained by substituting the predetermined period into the formula (3)

Wherein, K_i，kA measured delay scaling factor for each frequency bin in the first frequency bin group (i, k),

when the single frequency point is represented, the number of measurement opportunities obtained in unit time is averaged,

representing the number of measurement occasions, n, obtained on average in a unit time, at multiple frequencies_i，kThe number of measurements obtained by averaging each frequency point in the first frequency point group (i, k) in a preset period, where k is 0, 1, …, 2^i-g-1, i ═ g, g +1, …, 3, g ═ 0, 1, 2, or 3.

Illustratively, as an example, the frequency point number a in the tth available measurement window is grouped in the first frequency point (i, k)_i，k，tAnd the number of frequency points N in the first frequency point grouping group (i, k)_i，kWhen the same, the measurement delay scaling factor K of each frequency point in the first frequency point group (i, K)_i，kExpressed by equation (5):

in the formula (5), K_i，kA measured delay scaling factor for each frequency bin in the first frequency bin group (i, k),

grouping the second bins into groups (j, (t.2)^i-g+k)mod2^j-g) Number of middle frequency points, k is 0, 1, …, 2^i-g-1, i ═ g, g +1, …, 3, g ═ 0, 1, 2, or 3.

For example, in NR, in addition to configuring the MG of the full spectrum for the terminal device, the network may further divide the full spectrum frequency band into a first frequency band (a frequency band lower than 6GHz, which is also referred to as FR1 and refers to a low frequency in a normal case) and a second frequency band (a frequency band higher than 6GHz, which is also referred to as FR2 and refers to a high frequency in a normal case) according to the capability of the terminal device, so that the network device may configure the MG of the first frequency band and the MG of the second frequency band for the terminal device respectively.

It should be noted that the full-spectrum MG is suitable for the first frequency band and the second frequency band, and the MG of the first frequency band and the MG of the second frequency band are configured for the first frequency band and the second frequency band, respectively. The measurements of the first frequency band and the second frequency band can be performed independently without affecting each other. For the MG in the first frequency band and the MG in the second frequency band, the calculation method of the measurement delay scaling factor corresponding to the MG in the first frequency band is similar to the calculation method of the measurement delay scaling factor corresponding to the MG in the full frequency spectrum, which may be referred to the above description specifically, and is not described here again.

The following describes a calculation formula of the measured delay scaling factor for each frequency point of the frequency point group in the first frequency band and the second frequency band by using a specific example.

Specifically, as described above, when the MG of each frequency band is configured, the measurement delay scaling factor of the frequency point in each frequency band is calculated independently. Therefore, for the frequency points of the first frequency band or the second frequency band, when the measurement time delay scaling factor is calculated, only the frequency band in each frequency point group in the first frequency band and the second frequency point needs to be counted.

For example, in this embodiment of the application, since the first frequency point group (i, k) is for the full frequency band, when the full frequency band is divided into the first frequency band and the second frequency band, the grouping of the first frequency point group (i, k) may include: a third frequency bin group _ FR1(i, k) and a fourth frequency bin group _ FR2(i, k) are illustrated.

Wherein the third frequency point group _ FR1(i, k) has an available measurement window period equal to 20.2ⁱThe ms and SMTC window offsets are equal to the sum of the offset of the first MG and k times of the MGRP of the first MG, and are positioned in the set of frequency points in the first frequency band. As can be seen from the above analysis, the first frequency band is a frequency band with a frequency lower than 6GHz, and the first MG is an MG suitable for the first frequency band.

The fourth frequency bin group _ FR2(i, k) has an available measurement window period equal to 20.2ⁱThe ms and SMTC window offsets are equal to the sum of the offset of the second MG and k times the MGRP of the second MG, and are located in the set of frequency bins within the second frequency band. The second frequency band is a frequency band with a frequency higher than 6GHz, and the second MG is an MG suitable for the second frequency band.

For example, in the embodiment of the present application, it is assumed that the number of frequency points included in the third frequency point group _ FR1(i, k) is N_FR1，i，kThe number of times of measurement of the third frequency point group _ FR1(i, k) obtained by the terminal device on the t-th available measurement window of the preset period (within 160 ms) is a_{FR1，i，k，t}The fourth frequency bin group _ FR2(i, k) comprises a number of frequency bins N_FR2，i，kThe number of times of measurement of the fourth frequency point group _ FR2(i, k) on the tth available measurement window of the preset period (within 160 ms) acquired by the terminal device is a_{FR2，i，k，t}. Thus, the measured delay scaling factor K for each frequency bin in the first group of frequency bins (i, K) is referred to above_i，kThe method of (2) can obtain a measurement delay scaling factor K of each frequency point in the third frequency point group _ FR1(i, K)_FR1，i，kAnd a measured delay scaling factor K for each frequency bin in a fourth frequency bin group _ FR2(i, K)_FR2，i，k。

Specifically, in the first frequency band, the measurement delay scaling factor K of each frequency point in the third frequency point group _ FR1(i, K)_FR1，i，kExpressed by the following equation (6):

in the formula, K_FR1，i，kA measured delay scaling factor, N, for each bin in the third bin group _ FR1(i, k)_FR1，i，kThe number of bins, a, in the third bin group _ FR1(i, k)_{FR1，i，k，t}A measurement weight measured on the tth available measurement window for the third frequency point group _ FR1(i, k),

The available measurement windows overlap in time, k being 0, 1, …, 2^i-g-1, i ═ g, g +1, …, 3, g ═ 0, 1, 2, or 3.

In the embodiment of the present application, the fifth frequency bin group _ FR1(j, (t · 2)^i-g+k)mod2^j-g) The frequency point groups are frequency point groups in which the available measurement windows in the first frequency band are overlapped with the available measurement windows in the third frequency point group _ FR1(i, k) in terms of time, the number of the fifth frequency point groups may be one or multiple, and the number of the fifth frequency point groups is determined according to actual conditions, and the application does not limit the number of the fifth frequency point groups.

In the second frequency band, the measurement delay scaling factor K of each frequency bin in the fourth frequency bin group _ FR2(i, K)_FR2，i，kExpressed by the following equation (7):

in the formula, K_FR2，i，kA measured delay scaling factor, N, for each bin in a fourth bin group _ FR2(i, k)_FR2，i，kFor the number of frequency bins in said fourth frequency bin group _ FR2(i, k), a_{FR2，i，k，t}Measurement weights measured on the tth available measurement window for said fourth frequency bin grouping group _ FR2(i, k),

In the embodiment of the present application, the sixth frequency bin group _ FR2(j, (t · 2)^i-g+k)mod2^j-g) The frequency point groups are frequency point groups in which the available measurement windows in the second frequency band are overlapped with the available measurement windows of the fourth frequency point group _ FR2(i, k) in terms of time, the number of the sixth frequency point groups may be one or multiple, and the number of the sixth frequency point groups is determined according to actual conditions, and the application does not limit the number of the sixth frequency point groups.

Illustratively, as an example, the measurement weights a in the tth available measurement window are grouped into group _ FR1(i, k) at the third frequency point_{FR1，i，k，t}And the number of frequency bins N in the third frequency bin group _ FR1(i, k)_FR1，i，kAt the same time, the third frequency point group groMeasured delay scaling factor K for each bin in up _ FR1(i, K)_FR1，i，kExpressed by the following equation (8):

Step 53: and determining the measurement time delay of each frequency point in the first frequency point group during multi-frequency point measurement according to the measurement time delay scaling factor of each frequency point in the first frequency point group and the acquired single-frequency point measurement time delay of each frequency point in the first frequency point group.

For example, in the embodiment of the present application, through the step 52, the measurement delay scaling factor of each frequency point in each frequency point group in the full frequency band may be determined, or the measurement delay scaling factor of each frequency point in each frequency point group in the first frequency band (low frequency) and the second frequency band (high frequency) may be determined.

For example, after the measurement delay scaling factor of each frequency point in each frequency point group is determined, the measurement delay of each frequency point in each frequency point group during multi-frequency point measurement can be obtained according to the obtained single-frequency point measurement delay of each frequency point in each frequency point group.

For example, in the embodiment of the present application, a first frequency point packet represents one of all frequency point packets for description, so that after the measurement delay scaling factor of each frequency point in the first frequency point packet is calculated, according to the obtained single-frequency point measurement delay of each frequency point in the first frequency point packet, the single-frequency point measurement delay is multiplied by the measurement delay scaling factor of each frequency point, so that the measurement delay of each frequency point in the first frequency point packet when the multiple-frequency point is measured can be obtained.

The single-frequency point measurement time delay of the pilot frequency measurement can be obtained through the following formula:

max (T, nxmax (MGRP, SMTC window period, DRX cycle))

In the formula, T is a bottom-preserving single-frequency point measurement time delay of pilot frequency measurement, n is the number of measurement frequency points required to meet measurement accuracy, MGRP is a repetition period of MG, and DRX cycle is a Discontinuous Reception (DRX) cycle length of the terminal device, and if the terminal device operates in a continuous reception (non-DRX) mode, the DRX cycle is 0.

In the NR, a terminal device determines a measurement delay scaling factor of each frequency point in a first frequency point packet by acquiring a measurement opportunity number of the first frequency point packet in a preset period, according to the measurement opportunity number of the first frequency point packet in the preset period, a number of a plurality of frequency points in the first frequency point packet, and an available measurement window period of each frequency point in the first frequency point packet, and finally determines a measurement delay of each frequency point in the first frequency point packet when the measurement is performed at a multi-frequency point according to the measurement delay scaling factor of each frequency point in the first frequency point packet and the acquired single-frequency point measurement delay of each frequency point in the first frequency point packet. According to the technical scheme, the SMTC window period on each frequency point in each frequency point group is considered in the calculation of the measurement delay scaling factor, so that the calculated measurement delay scaling factor is fair to each frequency point in each frequency point group.

Fig. 6 is a flowchart illustrating a second embodiment of a method for determining inter-frequency measurement delay according to an embodiment of the present application. The method is applied to the network equipment. As shown in fig. 6, the method for determining inter-frequency measurement delay provided in the embodiment of the present application may include the following steps:

step 61: and determining the measurement weight of each frequency point group measured on each available measurement window in a preset period.

Each frequency point group is a set of a plurality of frequency points with the same available measurement window period and SMTC window offset configured at the measurement timing based on a synchronous signal block, the preset period is the maximum value in SMTC window period values, the starting time of the available measurement window is not earlier than the starting time of a measurement interval MG plus radio frequency switching time, and the ending time of the available measurement window is not later than the ending time of the MG minus the radio frequency switching time.

For example, in the embodiment of the present application, the network device first determines all frequency point groups according to the delay indicators (the available measurement window period and the SMTC window offset) of each frequency point, where each frequency point in each frequency point group has the same available measurement window period and the SMTC window offset, and then may determine, according to the delay indicators of the frequency points in each frequency point group, the measurement weight of each frequency point group measured on the available measurement window in the preset period.

It should be noted that, in this embodiment of the present application, the network device may dynamically adjust the measurement weight of each frequency point group measured on an available measurement window in a preset period according to the configured total number of measurement occasions.

Step 62: and sending the measurement weight of each frequency point group measured on each available measurement window in the preset period to the terminal equipment through a configuration instruction.

Illustratively, after the network device determines the measurement weight of each frequency point group measured on each available measurement window in the preset period, the network device generates a configuration instruction including the measurement weight of each frequency point group measured on each available measurement window in the preset period according to the measurement weight, and then sends the configuration instruction to the terminal device, so that the terminal device obtains the measurement weight of each frequency point group measured on each available measurement window in the preset period according to the received configuration instruction, and further determines the measurement weight of a certain frequency point group measured on each available measurement window in the preset period.

Illustratively, after dynamically adjusting the measurement weight of each frequency point group measured on an available measurement window in a preset period according to the configured total measurement opportunity number, the network device correspondingly and timely sends the measurement weight to the terminal device, so that the terminal device can measure the frequency points in each frequency point group more frequently, and the switching accuracy and flexibility of frequency point measurement are increased.

In the pilot frequency measurement time delay determination method in the embodiment of the application, network equipment sends the determined measurement weight grouped on each available measurement window in the preset period to terminal equipment, so that the terminal equipment can determine the measurement opportunity number of a certain frequency point group in the preset period according to the received measurement weight grouped on each available measurement window in the preset period, a foundation is laid for subsequently determining the measurement time delay scaling factor of each frequency point in the frequency point group, and the realization possibility provided by the measurement time delay scaling factor aiming at the equal time delay measurement of each frequency point when the multiple frequency points are determined is provided.
