Technical Field

The present application relates to the field of communications technologies, and in particular, to a measurement reporting method, apparatus, device, and medium.

Background

At present, when a New Radio (NR) system adopts coherent joint transmission (Coherent Joint Transmission, cqt) transmission, in order to reduce the influence of time synchronization error, frequency synchronization error or reciprocity error on cqt transmission, a measurement reporting method based on a tracking reference signal (TRACKING REFERENCE SIGNAL, TRS) may be adopted, and error cancellation is assisted by reporting by a User Equipment (UE). However, the prior art method of reporting measurement of time domain channel characteristics (Time Domain Channel Properties, TDCP) based on TRS cannot be directly applied, because TDCP is only used for reporting measurement at a single transmission point (Transmission Reception Point, TRP), and is not suitable for eliminating time-frequency synchronization error or reciprocity error between TRPs. In addition, in measurement reporting based on a type II Doppler codebook, network side equipment configures a measurement resource set for a terminal to carry out PMI measurement reporting, and based on the scene, if the network side equipment configures more measurement resource ports for the terminal, a measurement reporting method based on CSI-RS has the problem of time-frequency synchronization error. In summary, there is no corresponding solution for how to perform measurement reporting based on a reference signal to reduce or eliminate the effects of time-frequency synchronization errors or reciprocity errors.

Detailed Description

In the embodiment of the application, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, A and/or B, and can mean that A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In order to facilitate understanding of the aspects of the present application, the description will be given of the relevant content related to the present application.

In the NR system, TRS is used for time-frequency synchronization tracking. When measurement reporting is performed based on TRSs, one or more TRS resource sets may be associated in one reporting setting, each TRS resource set containing a plurality of TRS resources. In this case, the reporting amount can only be configured as 'none' or 'TDCP', where the TDCP reporting is used to solve the effect of doppler frequency offset on transmission. When the TDCP reporting is performed, the reporting setting is associated with an aperiodic or periodic resource setting, the number of TRS resource sets included in the resource setting may be 1,2 or 3, and the ue may assume that all TRS resources in the plurality of TRS resource sets have the same QCL-Type a/C parameter, and QCL-TypeD parameter (if applicable).

The measurement reporting method based on the TDCP comprises the following specific steps:

The TRS configuration, wherein the network side configures a reporting setting for the UE for TDCP measurement reporting, and the reporting device associates a Channel State Information (CSI) resource setting, wherein the CSI resource setting comprises N TRS resource sets, and N=1, 2 or 3. For periodic CSI resource settings, the UE will assume that all TRS resources in the multiple TRS resource sets have the same QCL-Type a/C parameters, and QCL-TypeD parameters (if applicable).

The method for reporting the TDCP comprises the following steps:

the network side configures Y delay values for the UE, wherein the number of the delay values is at most 4. The UE may report the magnitudes (also referred to as TDCP magnitudes) corresponding to the configured Y delay values, optionally, the UE may report the TDCP phase.

Specifically, the amplitude quantization method is as follows:

Quantization is performed using 4 bits, the quantization alphabet is 1-2 ^-(N-q)s, where q=0, 1,..2 ^Q-1,N＝2^Q, q=4, s= {1/4,1/2,2/3,3/4}.

When the delay number Y=1, only reporting the normalized TDCP amplitude of broadband quantization;

When the delay number Y is more than 1, reporting the normalized amplitude of broadband quantization and the broadband TDCP phase of each delay;

TDCP phase quantization method (4-bit uniform phase quantization) using the formula Quantization is performed, wherein:

C_TDCP＝[C₁...C_Y]

C_i∈{0,1,...,15}

When CJT transmission is adopted, in order to reduce the influence of time synchronization error, frequency synchronization error or reciprocity error on CJT transmission, a TRS-based measurement reporting method may be adopted, and UE reporting may be used to assist in error cancellation. However, the related art TDCP-based measurement report method cannot be directly applied because TDCP is only used for measurement report under a single TRP.

In addition, in measurement reporting based on a Type II doppler Type-IIDoppler codebook (i.e., type-II codebook for PREDICTED PMI, type II codebook indicated by a predicted precoding matrix), the network side device configures a measurement resource set for the terminal to perform PMI measurement reporting. When the time domain transmission characteristic of the measurement resource set is periodic or semi-persistent, the measurement resource set only comprises 1 measurement resource, and when the time domain transmission characteristic of the measurement resource set is non-periodic, the measurement resource set comprises K epsilon {4,8,12} measurement resources. The K measurement resources may correspond to different times.

If the network side device configures more measurement resource ports for the terminal, for example, a single TRP uses at most 128 ports (for example, 4 CSI-RS resources of 32 ports are used to construct a CSI-RS resource of 128 ports), or when multiple TRPs jointly use 128 or 256 ports, the measurement reporting method based on CSI-RS has a problem of time-frequency synchronization error.

In summary, there is no corresponding solution for how to perform measurement reporting based on a reference signal to eliminate the effect of time-frequency synchronization errors or reciprocity errors.

In order to solve the above technical problems, embodiments of the present application provide a method, an apparatus, a device, and a medium for reporting measurements, where the method and the apparatus are based on the same application conception, and since the principles of the method and the apparatus for solving the problems are similar, the implementation of the apparatus and the method may be referred to each other, and repeated descriptions are omitted.

Fig. 1 is a schematic flow chart of a measurement reporting method according to an embodiment of the present application, where the method is applied to a terminal, that is, is executed by the terminal. Specifically, the method comprises the following steps:

Step 101, receiving one or more first resource sets sent by a network side device, wherein the first resource sets are tracking reference signal TRS resource sets or channel state information CSI resource sets;

here, the network side device configures one or more first resource sets for the terminal, and sends the first resource sets to the terminal.

The TRS resource set comprises a plurality of TRS resources, and the CSI resource set comprises a plurality of CSI-RS resources.

Step 102, measuring resources in the first resource sets to obtain a measurement quantity when the first resource sets sent by the network side equipment are multiple, wherein the QCL parameters of a part of the first resource sets are the same, the associated index values are the same, the corresponding resource subgroups are the same or the corresponding time resources are different, the QCL parameters of a part of the resources are different, the associated index values are different, the corresponding resource subgroups are different or the corresponding time resources are the same, and reporting the measurement quantity to the network side equipment, and the measurement quantity comprises at least one of frequency difference, time delay difference, phase difference and TDCP amplitude.

Here, the time resource may be a slot, a symbol, or the like.

It should be appreciated that a portion of the plurality of first resource sets may have the same QCL parameters, the same associated index values, the same corresponding subset of resources, or different corresponding time resources, where a portion of the resources may refer to a portion of the first resource sets and all of the resources within the first resource sets, and/or may refer to a portion of the resources within a certain first resource set.

The plurality of first resource sets, a part of the resources have different QCL parameters, different associated index values, different corresponding resource subgroups or the same corresponding time resources, wherein the part of the resources refers to a part of the first resource sets, the first resource sets have different associated index values, different corresponding resource subgroups, the same corresponding time resources or different corresponding QCL parameters, and/or the part of the resources in a certain first resource set.

The method comprises the steps of determining a corresponding relation between the plurality of first resource sets and TRPs, determining a corresponding relation between the plurality of first resource sets and the TRPs, wherein the QCL parameters of one part of the plurality of first resource sets are the same, the associated index values are the same, the corresponding resource subgroups are the same or the corresponding time resources are different, the QCL parameters of one part of the plurality of first resource sets are different, the associated index values are different, the corresponding resource subgroups are different or the corresponding time resources are the same, and the purpose is to determine the corresponding relation between the plurality of first resource sets and the TRPs or the corresponding relation between the plurality of TRPs and the measurement report of the same TRP at different moments. For example, some first resource sets in the plurality of first resource sets correspond to the same TRP (e.g., determined according to the QCL parameter, a plurality of first resource sets corresponding to the same QCL parameter correspond to the same TRP; e.g., determined according to the index value, a first resource set associated with the same index value corresponds to the same TRP), some first resource sets correspond to different TRPs (e.g., determined according to the QCL parameter, a plurality of first resource sets corresponding to different QCL parameter correspond to different TRPs respectively; e.g., determined according to the index value, a first resource set associated with different index value corresponds to different TRP respectively). For another example, some of the first resource sets corresponding to the same time resource correspond to different TRPs, and some of the first resource sets corresponding to different time resources correspond to the same TRPs; of course, the terminal may determine the corresponding relationship with the TRP or determine the corresponding relationship with different time according to the combination of one or more of the above conditions.

The frequency difference may be a frequency difference between different TRPs or a frequency difference between different time points of the same TRP, the time delay difference may be a time delay difference between different TRPs or a time delay difference between different time points of the same TRP, and the phase difference may be a phase difference between different TRPs or a phase difference between different time points of the same TRP.

Wherein the frequency difference or the time delay difference may be represented by a first amplitude, i.e. the frequency difference is a specific value or amplitude, which is used to characterize the frequency difference or the time delay difference.

The terminal reports the measurement quantity to the network side equipment, specifically reports the frequency difference, the time delay difference, the phase difference and at least one of the TDCP amplitude values, so that the network side equipment can eliminate the influence of time-frequency synchronization errors or reciprocity errors based on the reported measurement quantity because the measurement quantity reported by the terminal comprises the measurement quantity measured among multiple TRPs. For example, the reported measurement quantity is the frequency difference or the phase difference among different TRPs, so that the frequency synchronization error can be eliminated, and if the reported measurement quantity is the time delay difference among different TRPs, the time synchronization error can be eliminated.

Step 103, under the condition that the first resource set sent by the network side equipment is one, measuring at least one group of resources in the first resource set to obtain a measurement quantity, and reporting the measurement quantity to the network side equipment, wherein the measurement quantity at least comprises a Precoding Matrix Indicator (PMI).

It should be understood that, in this step 103, the scenario of PMI measurement reporting is correspondingly performed by the network side device configuring a measurement resource set for the terminal in measurement reporting based on the type II doppler codebook. Here, measuring at least one group of resources in the first resource set means that each group of resources in the first resource set, which are at least one group of resources, is measured separately, and a PMI is obtained after each group of resources is measured. And measuring at least one group of resources in the first resource set to obtain a measurement quantity, thereby determining the corresponding relation between each group of resources in the first resource set and the antenna ports, and facilitating the measurement reporting of more ports.

In some embodiments, in the plurality of first resource sets:

All of the (i-1) th to i x N th first resource sets have the same QCL parameter or the (i-1) th to i x N th first resource sets correspond to different time resources, respectively, where i=1, 2..k, N, K is a positive integer greater than 1, and/or,

All of the j-th first set of resources, j+k-th first set of resources, j..j+ (N-1) K-th first set of resources have the same QCL parameters or j-th first set of resources, j+k-th first set of resources, j..j+ (N-1) K-th first set of resources correspond to different time resources, respectively, where j=1, 2..k, and/or,

The (p-1) th to p x K th first resource sets correspond to the same time resources or all resources within each of the (p-1) th to p x K th first resource sets, respectively, have the same QCL parameters, the resources within the sets having different QCL parameters between different first resource sets, wherein p = 1, 2..k, and/or,

The q-th first resource set, the q+n-th first resource set, the q..q+ (K-1) N first resource sets correspond to the same time resource or the q-th first resource set, the q+n-th first resource set, the q..q+ (K-1) N first resource sets, respectively, all resources within each of the q-th first resource set, the q..q+ (K-1) N first resource sets have the same QCL parameters, and the QCL parameters of the resources within the sets are different between different first resource sets, wherein q=1, 2..k.

The plurality of first resource sets satisfying the above condition are configured by the network side device, wherein the x (e.g., (p-1) k+1, q, etc.) th first resource set is the x (th) resource set configured by the network side device, or is determined in order of configured index values (IDs) from small to large.

Specifically, based on the definition of the plurality of first resource sets, an association relationship between the first resource sets and TRP, or an association relationship between the first resource sets and different times may be determined.

In order to facilitate understanding of the above embodiments, the following description will take the first resource set as a TRS resource set as an example.

When the method is used for eliminating frequency dyssynchrony, the network side equipment can associate one resource setting in one report setting, wherein K multiplied by N TRS resource sets (namely, CSI-RS resource sets configured with the parameters TRS-Info and corresponding to the higher-layer parameters NZP-CSI-RS-resource set) are configured in the resource setting, K represents the number of TRPs, and N represents the number of TRS resource sets at different moments of one TRP.

For example one, one reporting setting is associated with up to 4N TRS resource sets, where n=1, 2 or 3. The network side equipment firstly configures TRS resource sets of one TRP at different moments, and then configures a plurality of TRS resource sets of other TRPs. According to the configuration sequence of TRS resource sets, for periodic TRSs, network side equipment configures a first TRS resource set to an N-th TRS resource set, all resources in the N TRS resource sets have the same QCL-Type A/C/D parameter, N+1th to 2N-th TRS resource sets have the same QCL-Type A/C/D parameter, 2N+1th to 3N-th TRS resource sets have the same QCL-Type A/C/D parameter, all resources in the N TRS resource sets have the same QCL-Type A/C/D parameter, and the corresponding QCL parameters between groups are different. Here, as shown in fig. 2 and 3, k=4, n=3.

In making the measurements, the UE determines a frequency difference, a phase difference, or a TDCP value from multiple TRS resource sets with the same QCL parameters. That is, the UE performs measurement according to a plurality of TRS resource sets having the same QCL parameter, and obtains a frequency difference, a phase difference, or a TDCP value.

Optionally, the TRS resource sets configured by the network side device for the plurality of TRPs have the same interval in time.

In order to ensure that the reference time of the frequency offset measurement of each TRP is the same, and further the network side equipment can predict channel information of a plurality of TRPs at the same moment in the future through the report of the UE, optionally, the q-th TRS resource set, the q+Nth TRS resource set and the q+ - (K-1) N TRS resource sets are sent to the terminal in the same time slot, wherein q=1 and 2.

It should be understood that fig. 2 and fig. 3 correspond to the (i-1) n+1th to i×n first resource sets configured by the network side device, and all the resources in the N first resource sets have the same QCL parameter, for example, all the resources in the TRS set 1 (1 st TRS resource set) to TRS set 3 configured by the network side device for TRP1 (1 st TRP) have the same QCL parameter, which is QCL parameter 1.

Fig. 2 and fig. 3 also correspond to (i-1) n+1th to (i×n) th first resource sets configured by the network side device, respectively, and correspond to different time resources, for example, TRS set 1 (1 st TRS resource set) to TRS set 3 configured by the network side device for TRP1 (1 st TRP) are transmitted on different time resources (for example, time slots).

Fig. 2 also corresponds to the q-th first resource set, the q+n-th first resource set, and the q+ (K-1) N first resource sets configured by the network side device, respectively, corresponding to the same time resources, such as TRS set 1 (1 st TRS resource set) configured by the network side device for TRP1 (1 st TRP), TRS set 4 (4 th TRS resource set) configured by the network side device for TRP2 (2 nd TRP), TRS set 7 (7 th TRS resource set) configured by the network side device for TRP3 (3 rd TRP), and TRS set 10 (10 th TRS resource set) configured by the network side device for TRP4 (4 th TRP) are transmitted on the same time resource (e.g., time slot).

Fig. 2 and 3 also correspond to the q-th first resource set, the q+n-th first resource set, the q + (K-1) N first resource sets configured by the network side device, all resources in each first resource set have the same QCL parameter, the QCL parameters of the resources in the sets are different between different first resource sets, i.e., the QCL parameters corresponding to different first resource sets are different, such as all resources of TRS set 1 (1 st TRS resource set) configured by the network side device for TRP1 (1 st TRP) have the same QCL parameter 1, all resources of TRS set 4 (4 th TRS resource set) configured by the network side device for TRP2 (2 nd TRP) have the same QCL parameter 2, all resources of TRS set 7 (7 th TRS resource set) configured by the network side device for TRP3 (3 rd TRP) have the same QCL parameter, and all resources of TRS set 7 (4 th TRS resource set) configured by the network side device for TRP3 (2 nd TRP) have the same QCL parameter.

Example two, one reporting setting is associated with at most 3K TRS resource sets, where k=1, 2,3 or 4, the number order of TRSs is different from example one, all resources in the jth TRS resource set, the j+kth TRS resource set, the j+2kth TRS resource set have the same QCL parameter, j=1, 2..k, as shown in fig. 4 and 5, where in fig. 4 and 5 j=1, 2,3, 4;K =4.

In order to ensure that the reference time of the frequency offset measurement of each TRP is the same, and further the network side equipment can predict channel information of a plurality of TRPs at the same moment in the future through the report of the UE, optionally, the (i-1) th first resource set (n+1) to the (i×N) th first resource set are sent to the terminal in the same time slot, wherein q=1, 2. For example, the first to nth TRS resource sets may be transmitted in the same time slot, the n+1th to 2nth TRS resource sets may be transmitted in the same time slot, the 2n+1th to 3nth TRS resource sets may be transmitted in the same time slot, and the TRS set 1 (1st TRS resource set), the TRS set 2 (2nd TRS resource set), the TRS set 3 (3rd TRS resource set), and the TRS set 4 (4th TRS resource set) may be transmitted to the terminal in the same time slot, as in the TRS pattern of fig. 4.

It should be understood that, in fig. 4 and fig. 5, the network side device configures the jth first resource set, the jth+k first resource set, and all resources in the j+ (N-1) K first resource sets have the same QCL parameters, e.g., all resources in TRS set 1 (1 st TRS resource set), TRS set 5 (5 th TRS resource set), and TRS set 9 (9 th TRS resource set) configured by the network side device for TRP1 (1 st TRP) have the same QCL parameters, which are QCL parameters 1.

Fig. 4 and fig. 5 also correspond to the network side device configuring the jth first resource set, the jth+kth first resource set, and the..j+ (N-1) K first resource sets, which respectively correspond to different time resources, e.g., TRS set 1 (1 st TRS resource set), TRS set 5 (5 th TRS resource set), and TRS set 9 (9 th TRS resource set) configured by the network side device for TRP1 (1 st TRP) are transmitted on different time resources (e.g., timeslots).

Fig. 4 further corresponds to the (p-1) th k+1 first resource set to the p×k th first resource set configured by the network side device, and each corresponds to the same time resource, for example, TRS set 1 (1 st TRS resource set) configured by the network side device for TRP1 (1 st TRP), TRS set 2 (2 nd TRS resource set) configured by the network side device for TRP2 (2 nd TRP), TRS set 3 (3 rd TRS resource set) configured by the network side device for TRP3 (3 rd TRP), and TRS set 4 (4 th TRS resource set) configured by the network side device for TRP4 (4 th TRP) are transmitted on the same time resource (e.g., time slot).

Fig. 4 and fig. 5 also correspond to the (p-1) th k+1 first resource set to the p×k first resource set configured by the network side device, all resources in each of the first resource sets have the same QCL parameters, the QCL parameters of the resources in the sets are different between the different first resource sets, that is, the corresponding QCL parameters are different between the different first resource sets, for example, all resources of the TRS set 1 (1 st TRS resource set) configured by the network side device for TRP1 (1 st TRP) have the same QCL parameters 1, all resources of the TRS set 2 (2 nd TRS resource set) configured by the network side device for TRP2 (2 nd QCL parameters 2), all resources of the TRS set 3 (3 rd TRS resource set) configured by the network side device for TRP3 (3 rd TRPs) have the same QCL parameters 3, and all resources of the TRS set 4 (4 th TRS resource set) configured by the network side device for TRP4 (4 th TRS) have the same QCL parameters.

It should be noted that, in addition to the above configuration sequence of the TRS resource sets, the correspondence between the TRS resource sets and the TRP or the corresponding relationship between the TRS resource sets and different time points may be determined according to the index values of the TRS resource sets, for example, the values of the TRS resource sets in fig. 2, fig. 3, fig. 4, and fig. 5 may be arranged in a descending order, for example, the TRS set 1 represents a TRS resource set having a smallest index value among all TRS resource sets associated with one reporting setting, and the index values of all TRS resource sets associated with one reporting setting represented by the TRS set 5 are arranged in a fifth TRS resource set. After determining the association relation between the TRS resource set and the TRP or different moments, the UE measures the TRS resource set and measures the frequency difference, the phase difference or the TDCP value among a plurality of moments of one TRP respectively.

When used for time out-of-sync cancellation or reciprocity error cancellation, the network side device may associate one resource setting in one reporting setting, where K TRS resource sets are configured in the resource setting, where K represents the number of TRPs.

Accordingly, in some embodiments:

(1) All the resources in each first resource set have the same QCL parameters, and the QCL parameters of the resources in the sets are different among different first resource sets, namely the QCL parameters corresponding to the resources contained among the different first resource sets are different. In the following, by way of example three, one reporting setting is associated with up to 4 TRS resource sets.

In this example, QCL-Type a/C/D parameters corresponding to different TRS resource sets are different and correspond to different TRPs, respectively, as shown in fig. 6. This situation may be used for time synchronization error measurement or reciprocity error measurement. Optionally, the symbol or subcarrier locations in each TRS resource set are different. This facilitates the transmission of multiple TRPs using different beams.

In the invention, the QCL-Type A/C/D parameter or the QCL parameter corresponding to the resource set, namely the QCL-Type A/C/D parameter or the QCL parameter corresponding to (all) resources in the resource set.

Referring to fig. 6, the TRS resources within each TRS resource set have the same QCL-Type a/C/D parameters.

Or (2) a portion of the resources within each of said first set of resources have different QCL parameters;

Optionally, part of the resources in each first resource set have different QCL parameters, where the time resources corresponding to the resources having the same QCL parameters in the same first resource set are the same, or the resources having different QCL parameters correspond to the same time resources in the same first resource set.

Four examples, one reporting setting is associated with up to 3 TRS resource sets, are described below by way of example four.

The TRS resources in each TRS resource set have different QCL-Type A/C/D parameters, namely, one TRS resource set supports the transmission of a plurality of TRPs, and 3 TRS resource sets are transmitted in different time slots and can be used for eliminating frequency errors or time errors.

Case 1 one set of TRS resources contains at most 8 TRS resources, occupies 4 or 2 slots, each slot contains 2 or 4 TRS resources, and the transmission patterns are as shown in fig. 7 and 8.

It should be understood that, resources in the first resource set corresponding to fig. 7 have different QCL parameters, where the time resources corresponding to the resources having the same QCL parameters in the same first resource set are the same, for example, TRS resource 1 and TRS resource 2 have the same QCL parameters, are both QCL parameters 1, and are transmitted in the same time slot n.

Fig. 8 corresponds to resources in the first resource set having different QCL parameters, where resources having different QCL parameters, such as TRS resource 1 and TRS resource 2 having the same QCL parameter, are QCL parameter 1, TRS resource 3 and TRS resource 4 having the same QCL parameter, are QCL parameter 2, and TRS resource 1, TRS resource 2, TRS resource 3 and TRS resource 4 are transmitted in the same time slot n.

Case 2 one TRS resource set contains up to 4 TRS resources, occupies 4 or 2 slots, and the transmission patterns are as shown in fig. 9 and 10.

In the transmission patterns of case 1 and case 2 above, the TRS resources of each slot may have different QCL-Type a/C/D parameters, or each TRS resource may have different QCL-Type a/C/D parameters. Here, for the TRS resource set occupying 4 slots, the TRS resources of the first 2 slots and the TRS resources of the second 2 slots may also have different QCL-Type a/C/D parameters, which is not exemplified one by one.

Or (3) each first resource set is associated with an index value, and the index values associated with different first resource sets are different;

Here, the index value is used to characterize TRP. The following is described by way of example five:

Example five, one reporting setting is associated with up to P TRS resource sets, each TRS resource set being associated with an index value, wherein the index value is used to characterize a TRP, and different index values are indicative of different TRPs.

And the UE performs measurement based on the TRS resource sets with the same index value at different moments, determines the frequency difference, the phase difference or the TDCP value of the same TRP at different moments and reports.

Or (4) each of the first resource sets corresponds to a subset of resources, or each of the subsets of resources corresponds to a time resource.

Here, in case that each of the first resource sets corresponds to one resource subgroup, the resource subgroup is used to characterize TRP. The following is described by way of example six:

example six, one resource setting explicitly configures K resource subgroups, each resource subgroup corresponding to one TRP (e.g., all TRS resources in a TRS resource subgroup have the same QCL parameter), or one resource setting explicitly configures N resource subgroups, each resource subgroup corresponding to one transmission time instant (e.g., all TRS resources in a TRS resource subgroup are transmitted within a particular slot interval);

When measurement reporting is performed, the UE performs measurement on TRS resources in the resource subgroups, determines time delay difference, frequency difference or phase difference between TRPs and reports the time delay difference, the frequency difference or the phase difference, or the time difference or the TDCP value of the same TRP at different moments is determined and reported by the UE based on the TRS resource subgroups at different moments.

In some embodiments, in step 102, the measuring the resources in the first plurality of resource sets to obtain a measurement quantity includes the following a and/or B and/or C and/or D:

measuring resources which are in the plurality of first resource sets and have the same QCL parameters or are associated with the same index values or correspond to the same resource subgroups or correspond to different time resources to obtain measurement quantities;

It should be understood that the resources satisfying the above conditions in the plurality of first resource sets may be resources in the plurality of first resource sets in units of the first resource sets, so that the network side device may be corresponding to a situation in which the plurality of first resource sets are configured for one TRP, where the measurement amounts are measurement amounts of the same TRP at different moments.

The resources satisfying the above conditions in the plurality of first resource sets may also be part of the resources in a certain first resource set, so that the situation that the network side device configures the plurality of TRPs in one resource set can be corresponded, and in this case, the measurement quantity is the measurement quantity between different TRPs.

Optionally, a specifically includes:

selecting one or more resources from a plurality of first resource sets, which have the same QCL parameters or are associated with the same index values or correspond to the same resource subgroup or correspond to different time resources as reference resources;

Optionally, B specifically includes:

selecting one or more first resource sets from the first resource sets, which are associated with the same index value or correspond to the same resource subgroup or correspond to different time resources, as a reference resource set;

And measuring the resources in the reference resource set and the resources in other resource sets except the reference resource set in the first resource sets which are associated with the same index value or correspond to the same resource subgroup or correspond to different time resources, so as to obtain a measurement quantity.

Measuring resources which are in the first resource sets and have different QCL parameters or are associated with different index values or correspond to different resource subgroups or correspond to the same time resources to obtain measurement quantities;

It should be understood that the resources satisfying the above condition in the plurality of first resource sets may be in units of first resource sets, for example, all the resources in each of the plurality of first resource sets have the same QCL parameter, but the corresponding QCL parameters are different between different first resource sets. In this case, the measurement quantity is a measurement quantity between different TRPs.

The resources satisfying the above conditions in the plurality of first resource sets may be part of the resources in a certain first resource set, so that the situation that the network side device configures the plurality of TRPs in one resource set may be corresponded, where the measurement quantity is a measurement quantity between different TRPs.

Optionally, C specifically includes:

Selecting one or more resources from a plurality of first resource sets, which have different QCL parameters or are associated with different index values or correspond to different resource subgroups or correspond to the same time resources as reference resources;

And measuring other resources except the reference resource in the reference resource and the resource resources with different QCL parameters or associated different index values or corresponding to different resource subgroups or corresponding to the same time resource in the plurality of first resource sets to obtain measurement quantity.

D, measuring resources in the first resource sets, which are associated with different index values or correspond to different resource subgroups or correspond to the same time resources, so as to obtain measurement quantities;

It should be understood that, among the plurality of first resource sets, a resource set satisfying the above condition corresponds to a case where the network side device allocates different first resource sets for different TRPs, in which case the measurement quantity is a measurement quantity between different TRPs.

Optionally, D specifically includes:

selecting one or more resources from a plurality of first resource sets, and associating different index values or corresponding to different resource subgroups or corresponding to the first resource sets of the same time resource as reference resources;

And measuring other resources except the reference resource in the reference resource set and the first resource sets, which are associated with different index values or correspond to different resource subgroups or correspond to the same time resource, so as to obtain a measurement quantity.

Optionally, the reference first resource set is the first resource set with the smallest index value.

Optionally, the plurality of reference first resource sets includes a plurality of first resource sets for which burst transmissions (e.g., TRS bursts) occur earliest.

For ease of understanding, the following is described by way of example seven:

The network side equipment is assumed to configure 8 TRS resource sets for the UE, and 4 TRPs serve the UE, so that the number of the TRS resource sets corresponding to each TRP is 2. The TRS resource sets (hereinafter, abbreviated as TRSs) are respectively numbered:

TRP 1:TRS1,TRS 8;

TRP 2:TRS2,TRS 3;

TRP 3:TRS 9,TRS11;

TRP 4:TRS 4,TRS 6;

1) With TRS1 as a reference, the UE calculates and reports measurement quantities according to other TRSs and TRS1 respectively.

2) The UE reports the measurement quantities between the other TRSs and the several reference TRSs with reference TRSs 1,2,9,4, respectively.

In some embodiments, the methods of the present application further comprise:

Determining a quantization range of the measurement quantity;

Quantizing the measurement quantity in the quantization range to obtain a quantized measurement quantity;

Correspondingly, in the step 102, reporting the measurement quantity to the network side device includes:

And reporting the quantized measurement quantity to the network side equipment.

After the terminal side quantifies the measurement quantity, the measurement quantity is reported to the network side equipment, so that the resources occupied by data transmission can be saved.

In some alternative embodiments, the measurement includes a frequency difference or a time delay difference, and the determining the quantization range of the measurement includes:

Determining a phase difference corresponding to the measurement quantity;

And determining the quantization range of the measured quantity after the phase difference module 2 pi corresponding to the measured quantity.

Here, considering that the value of the phase difference modulo 2pi corresponding to the frequency difference is unchanged, it is not necessary to report all the frequency differences, only the frequency difference with the phase difference within 2pi corresponding to the frequency difference is selected to report, and the specific quantization method is related to the subcarrier interval. The method can be suitable for a mode that the network side equipment performs transmission pre-compensation/pre-processing according to the report of the UE, eliminates the frequency asynchronous error and enables the channel to be flattened in time.

Assuming that the frequency is f, the phase corresponding to the specific delay t is e ^j2πft.

Considering that the value of the phase difference module 2 pi corresponding to the time delay difference is unchanged, reporting of all the time delay differences is not needed, only the time delay difference with the phase difference within the range of 2 pi corresponding to the time delay difference is selected for reporting, and a specific quantization method is related to subcarrier spacing. The method can be suitable for a mode that the network side equipment performs transmission pre-compensation/pre-processing according to the report of the UE and eliminates time asynchronous errors.

Assuming that the frequency of a subcarrier is f _i, the phase corresponding to a specific delay difference tau is

In some embodiments, the measuring quantity comprises a frequency difference or a time delay difference, and the quantizing the measuring quantity in the quantizing range to obtain a quantized measuring quantity comprises:

determining a multiplier value and a remainder of the measurement relative to the quantization range;

quantizing the remainder in the quantization range to obtain a quantized value;

Correspondingly, in the step 102, the reporting the quantized measurement value to the network side device includes:

And reporting the multiple value and the quantized value to the network side equipment.

Specifically, the measurement quantity comprises a frequency difference, a first multiplier value and a first remainder of the frequency difference relative to the quantization range are determined, and the remainder is quantized in the quantization range to obtain the first multiplier value;

when the absolute value of the frequency difference is considered, i.e. the quantized value is not modulo 2pi, the frequency difference can be reported in two parts. Firstly, determining a quantization range of a frequency difference (such as the maximum quantization range determined according to subcarrier intervals or central frequency points or high-level parameters configured on a network side), then, calculating a first multiple value and a first remainder of the frequency difference relative to the maximum frequency value in the quantization range by the UE, and finally, reporting the first multiple value as a first part by the UE, and quantizing the remainder in the quantization range to obtain the first value which is reported as a second part by the UE.

If the measured frequency difference is 500Hz, the UE divides the 500Hz by 400Hz to obtain a quotient of 1, and the remainder is 100Hz, the UE determines that the report value of the first part is 1, and the report value of the second part is 100Hz, and the quantized value is quantized according to the [0,400] range.

Correspondingly, the step of reporting the quantized frequency difference to the network side device includes:

And reporting the first multiple value and the first value to the network side equipment.

By adopting the two-step quantization method, the resources occupied by data transmission can be further saved.

The measurement quantity comprises a time delay difference, a second time value and a second remainder of the time delay difference relative to the quantization range are determined;

Quantizing the second remainder in the quantization range to obtain a second numerical value;

When the absolute value of the delay difference is considered, namely the quantized value does not modulo 2pi, the frequency difference can be reported through the two parts. Firstly, determining a quantization range of the delay difference (such as the maximum quantization delay difference determined according to the subcarrier interval), then, calculating a second multiple value and a second remainder of the delay difference relative to the maximum delay difference in the quantization range by the UE, and finally, reporting the second multiple value as a first part by the UE, and quantizing the second remainder in the quantization range to obtain a second value which is reported as a second part by the UE.

For example, if the maximum quantization range determined according to the subcarrier spacing is 2778ns, and if the measured delay difference is 4000ns, the UE divides the 4000ns by 2778ns to obtain a quotient of 1, and the remainder is 1222ns, the UE determines that the first part report value is 1, and the second part report value is 1222ns, and the quantized value is quantized according to the [0,2778ns ] range. Correspondingly, the step of reporting the quantized delay difference to the network side equipment comprises the step of reporting the second multiple value and the second value to the network side equipment.

In an alternative embodiment, the measurement includes a frequency difference, and determining a quantization range for the frequency difference includes at least one of:

① Determining the quantization range of the frequency difference according to the subcarrier spacing;

assuming that the unit of delay value is a slot level and the minimum delay value is 1 slot, then:

Taking a 15kHz subcarrier spacing as an example, each time slot corresponds to a time length of 1ms, in which case the frequency difference may be quantized within 0-1000Hz (corresponding to 1/1 ms);

For a 30kHz subcarrier spacing, the corresponding time length of each slot is 0.5ms, then the frequency difference is quantized within 0-2000 Hz;

For a 60kHz subcarrier spacing, each slot corresponds to a time length of 0.25ms, and the frequency difference is quantized within 0-4000 Hz.

In particular, a uniform quantization manner may be used within a certain quantization range, such as quantization at 50Hz intervals within the [0,2000Hz ] range.

② Determining a quantization range of the frequency difference according to a center frequency point, wherein the center frequency point is a current center frequency point, a center frequency point configured by a network side or a predefined center frequency point;

if the frequency difference is used for TRP selection (e.g., selecting TRP with a relatively small frequency error), the selected TRP is cqt transmitted, which can reduce or eliminate the frequency error. In this case, the network side device may pay more attention to the absolute range of the frequency difference, so the quantized value cannot modulo 2pi, and the quantized range may be determined according to the center frequency point.

Case 1: the quantization range of the frequency difference is related to the current center frequency point, e.g. different center frequency points correspond to quantization ranges of different frequency differences. For example, optionally, with a maximum frequency offset indicator for the device. If the maximum frequency deviation is 0.1ppm at 6GHz, the corresponding maximum frequency difference is 600Hz, namely the quantization range of the frequency difference is 0-600Hz, and similarly, if the maximum frequency difference is 400Hz at 4GHz, namely the quantization range of the frequency difference is 0-400Hz.

Case 2: the quantization range of the frequency difference is related to a specific center frequency point (network side configuration or predefined center frequency point), such as the quantization range using the same frequency difference at each center frequency point. The quantization range may be determined in terms of a maximum center frequency point, such as a maximum frequency range according to 6GHz (or 7.125 GHz). If the maximum frequency deviation is 0.05ppm, the quantization range of the frequency difference is 0-0.05ppm x 6GHz, namely 0-300Hz.

③ And determining the quantization range of the frequency difference according to the high-level parameters configured on the network side.

In an alternative embodiment, the measurement includes a delay difference, and determining a quantization range of the delay difference includes at least one of:

① Determining the quantization range of the delay difference according to the subcarrier interval;

Taking 15kHz subcarrier intervals as an example, if the reporting granularity of the delay difference is 1RB at minimum, and the frequency interval corresponding to each RB is 15kHz multiplied by 12=180 kHz, in this case, the delay difference is quantized within 0-1/180 kHz=5556 ns;

Taking 15kHz subcarrier spacing as an example, if the reporting granularity of the delay difference is 32RB, the frequency interval corresponding to each 32 RBs is 15khz×12×32=5760 kHz, and in this case, the delay difference is quantized within 0-1/5760 khz=174 ns;

Taking a 30kHz subcarrier interval as an example, if the reporting granularity of the delay difference is 1RB, and the frequency interval corresponding to each RB is 30kHz multiplied by 12=360 kHz, in this case, the delay difference is quantized within 0-1/360 kHz=2778 ns;

Taking a 30kHz subcarrier interval as an example, if the reporting granularity of the delay difference is 4RB, the frequency interval corresponding to each 4 RBs is 30khz×12×4=1440 kHz, and in this case, the delay difference is quantized within 0-1/1440 khz=694 ns.

In particular, a uniform quantization scheme may be used within a certain quantization range, such as quantization at 100ns intervals within [0,5556ns ].

② And determining the quantization range of the delay difference according to the reporting granularity of the delay difference.

Here, the measurement quantity includes a frequency difference. Optionally, the frequency difference is a frequency difference of a subband, i.e. a frequency difference obtained according to the reporting granularity of cqt CSI. The network side equipment performs pre-compensation (to reduce or eliminate the influence of the frequency synchronization error) based on the frequency difference of each sub-band, or adjusts the CSI reporting granularity according to the corresponding frequency difference. Compared with the method that the whole broadband only reports one frequency difference, the pre-compensation effect after the sub-band reporting is better.

In some embodiments, the measurement includes a delay difference, optionally, the delay difference is a frequency difference of subbands, i.e., a delay difference obtained according to a reporting granularity of CJT CSI. The network side equipment uses corresponding delay difference to pre-compensate based on each sub-band, or adjusts the CSI reporting granularity according to the corresponding delay difference. Compared with the whole broadband reporting only one time delay difference, the pre-compensation effect after the sub-band reporting is better.

Optionally, the delay difference is reported according to the phase change granularity corresponding to the delay. By way of example, assuming that the phase difference change introduced by the delay difference within 4 Resource Blocks (RBs) is less than a particular arc (or a particular threshold, e.g., pi/2, where the threshold is configured by higher layer parameters or reported by the UE), the UE reports the delay difference corresponding to every 4 RBs, and considers that the channels within 4 RBs can use the same delay difference compensation.

Here, the time delay is a different concept from the above-described delay. The time delay refers to propagation delay, multipath delay and always introduced delay among multiple TRPs. For example, on the order of less than the CP length, or slightly greater than the CP length, etc. And the delay in the frequency synchronization error cancellation refers to a relatively long period of time, such as 4 slots, 10 slots, etc.

In some embodiments, the measurement includes a delay difference, and in particular, the UE determines the first phase difference based on a set of TRS resources with the same 2 QCL parameters or based on a set of TRS resources with different 2 QCL parameters.

The first phase difference determined according to the TRS resource sets with the same 2 QCL parameters is the phase difference of the same TRP at two different moments, and the first phase difference determined according to the TRS resource sets with different 2 QCL parameters is the phase difference between the two TRPs.

Optionally, the UE performs measurement according to one or more reference TRS resource sets, or according to one or more CSI-RS related resource units (e.g., CSI-RS resource ports, CSI-RS resources, CSI-RS resource sets), and correspondingly, the UE reports a phase difference between different TRS resource sets and the reference TRS resource sets, or reports a phase difference between the CSI-RS related resource units and the reference CSI-RS related resource units.

The TRS resource set is described below as an example.

The reference TRS resource set may be the TRS resource set having the smallest index value among all the TRS resource sets associated with the reporting setting, or may be a plurality of TRS resource sets in which the TRS burst transmission occurs earliest, and each TRP defines a reference TRS resource set.

TRP 1:TRS1,TRS 8;

TRP 2:TRS2,TRS 3;

TRP 3:TRS 9,TRS11;

TRP 4:TRS 4,TRS 6;

1) With TRS1 as a reference, the UE calculates and reports the phase difference according to the other TRS and TRS1, and since the phase difference between TRS1 and TRS1 is 0, reporting is not required.

2) And respectively taking TRSs 1 and 2,9,4 as references, and reporting phase differences between other TRSs and the reference TRSs by the UE.

Accordingly, in the step 102, the measurement quantity is reported to the network side device, including at least one of the following:

1) Reporting a plurality of first phase differences to the network side equipment, wherein one delay value corresponds to one or more first phase differences, and the delay value is configured by the network side equipment;

Here, the delay value represents a time interval corresponding to the two first phase differences.

Here, it is assumed that the network side device configures 6 TRS resource sets, a TRS resource set 1 to a TRS resource set 6, respectively corresponding to 3 TRPs, where the TRS resource set 1 and the TRS resource set 2 have QCL parameters 1, the TRS resource set 3 and the TRS resource set 4 have QCL parameters 2, and the TRS resource set 5 and the TRS resource set 6 have QCL parameters 3;

The network side equipment configures a delay value, the delay value can be applicable to all TRPs, if the delay value is 5 slots, the UE can respectively measure a TRS resource set 1 and a TRS resource set 2 with QCL parameters or the same index value or the same resource subgroup, the TRS resource set 1 and the TRS resource set 2 are measured at intervals of 5 slots, and then, difference value calculation is carried out on the obtained two phase values, and a first phase difference is obtained and reported. And similarly, the first phase difference among other TRS resource sets is obtained according to the method, and then all the phase differences are reported. Thus, one delay value corresponds to a plurality of first phase differences.

Another case is that the network side device configures a plurality of delay values, each of which is applicable to only a part of TRP. If the network side equipment configures 3 delay values, namely 2 slots, 3 slots and 4 slots respectively, the UE measures TRS resource set 1 and TRS resource set 2 (corresponding to one TRP) with QCL parameters or the same index value or the same resource subgroup at intervals of 2 slots to obtain a first phase difference and report the first phase difference, and measures TRS resource set 3 and TRS resource set 4 (corresponding to one TRP) with QCL parameters or the same index value or the same resource subgroup at intervals of 3 slots to obtain a first phase difference and report the first phase difference, and measures TRS resource set 5 and TRS resource set 6 (corresponding to one TRP) with QCL parameters or the same index value or the same resource subgroup at intervals of 4 slots to obtain a first phase difference and report the first phase difference.

2) Reporting a plurality of delay values and at least two first phase differences corresponding to each delay value to the network side equipment, wherein the number of the first phase differences corresponding to each delay value is the same;

The following is described by way of example eight:

In the eighth example, the network side device uses 3 TRPs to perform CJT transmission for the UE, the UE reports 2 delay values, and uses the TRS resource set corresponding to the first TRP of the earliest transmission TRS as a reference, the UE reports the phase difference between each TRP under each delay value and the reference TRP (the first TRP of the earliest transmission TRS) reference time, in this case, even if the time selectivity of the multiple TRPs is different, the UE needs to determine a set of delay values together according to the time domain channel variation situation of each TRP, see fig. 11, and the corresponding phase difference number under each delay value is the same.

When a phase difference is calculated using a specific TRP as a reference, the phase difference of the TRP at different delay values is caused only by doppler shift or the like, not by clock shift, and when the phase difference change is small, the phase value of the reference TRP (or the reference TRS resource set) at different delay values may not be reported, see fig. 12.

3) Reporting a plurality of delay values and at least two first phase differences corresponding to each delay value to the network side equipment, wherein the number of the first phase differences corresponding to each delay value is different;

Under the reporting scheme, not every TRP reports the phase difference under each delay value, if the frequency offset of a certain TRP is smaller, the phase difference under part of the delay values can not be reported.

As shown in fig. 13, when TRP1 at the reference time is taken as a reference and other TRPs are received according to the receiving frequency of TRP1, the phase difference change of TRP1 at different delay values is relatively small, so that the phase difference of TRP1 may not be reported at a partial delay value.

4) And reporting a plurality of delay values and a precoding matrix formed by at least two first phase differences corresponding to each delay value to the network side equipment.

The terminal may obtain a plurality of first phase differences according to the TRS resource set or the CSI-RS related resource unit measurement, and then quantize the plurality of first phase differences according to a codebook to obtain a precoding matrix. As in fig. 11, the ue quantizes the first phase difference using a vector (codebook) of 6*1 or quantizes the first phase difference using vectors (codebooks) of 2 3*1.

In some embodiments, the measurement quantity includes a TDCP value;

When the TDCP reporting is performed, the UE may report the TDCP value of the channel corresponding to the same TRP (e.g., two first resource sets with the same QCL parameter and different corresponding time resources) between 2 times, or may select one TRP (e.g., a TRS resource set) as a reference, and the UE reports the TDCP values of all the TRPs and the reference TRP under a plurality of delay values.

TRP 1:TRS1,TRS 8;

TRP 2:TRS2,TRS 3;

TRP 3:TRS 9,TRS11;

TRP 4:TRS 4,TRS 6;

The reported TDCP value may be:

1) With TRS1 as a reference, other TRSs and TRS1 of the UE respectively calculate and report TDCP values, and as the TDCP value between the TRS1 and the TRS1 is 0, the UE only needs to report 7 TDCP values (comprising TDCP amplitude and TDCP phase) without reporting;

2) Respectively taking TRS1 and 2,9,4 as references, and reporting TDCP values between other TRSs and the reference TRSs by the UE;

3) The UE reports the TDCP amplitude values with TRS1 and 2,9,4 as references, and reports the TDCP phase values between other TRSs and TRS1 with TRS1 as references, respectively.

1) Reporting a plurality of TDCP values to the network side equipment, wherein one delay value corresponds to one or more TDCP values, and the delay value is configured by the network side equipment;

Here, the delay value is configured by the network side device, and the UE only reports the TDCP value corresponding to the delay value. The delay value represents the time interval corresponding to the two measurement quantities.

Assuming that the network side equipment configures 6 TRS resource sets, wherein the TRS resource sets 1-6 correspond to 3 TRPs respectively, the TRS resource set 1 and the TRS resource set 2 have QCL parameters 1, the TRS resource set 3 and the TRS resource set 4 have QCL parameters 2, and the TRS resource set 5 and the TRS resource set 6 have QCL parameters 3;

The network side equipment configures a delay value, the delay value can be applicable to all TRPs, if the delay value is 5 slots, the UE can measure TRS resource set 1 and TRS resource set 2 with the same QCL parameter or the same index value or the same resource subgroup at intervals of 5 slots to obtain a TDCP value (such as TDCP amplitude) and report the TDCP value, the UE measures TRS resource set 3 and TRS resource set 4 with the same QCL parameter or the same index value or the same subgroup at intervals of 5 slots to obtain a TDCP value (such as TDCP amplitude) and report the TDCP value, and the UE measures TRS resource set 5 and TRS resource set 6 with the same QCL parameter or the same index value or the same subgroup at intervals of 5 slots to obtain a TDCP value (such as TDCP amplitude) and report the TDCP value, so that the delay value corresponds to a plurality of TDCP values.

Another case is that the network side device configures a plurality of delay values, each of which is applicable to only a part of TRP. If the network side equipment configures 3 delay values, namely 2 slots, 3 slots and 4 slots respectively, the UE measures TRS resource set 1 and TRS resource set 2 (corresponding to one TRP) with a QCL parameter or the same index value or the same resource subgroup at intervals of 2 slots to obtain a TDCP value (such as a TDCP amplitude) and reports the TDCP value, and measures TRS resource set 3 and TRS resource set 4 (corresponding to one TRP) with a QCL parameter or the same index value or the same resource subgroup at intervals of 3 slots to obtain a TDCP value (such as a TDCP amplitude) and reports the TDCP value, and the UE measures TRS resource set 5 and TRS resource set 6 (corresponding to one TRP) with a QCL parameter or the same index value or the same resource subgroup at intervals of 4 slots to obtain a TDCP value (such as a TDCP amplitude) and reports the TDCP value.

When the delay value corresponding to each TRP exceeds 1, the UE also reports the TDCP phase.

2) Reporting one or more delay values and a plurality of TDCP values corresponding to each delay value to the network side equipment;

The delay value may also be reported by the UE due to the different channel time-varying characteristics of the multiple TRPs. One delay value may correspond to a plurality of TDCP values (TDCP magnitude and/or TDCP phase), and one delay value may be used for each of a plurality of TRPs or may be applicable only to a specific TRP.

Optionally, when the network side configures the kxn TRS resource sets, the UE associates with 2K TRS resource sets, or only 2 TRS resource sets, for one delay value.

3) Reporting a plurality of TDCP values and a plurality of first phase differences to the network side equipment;

If the TDCP measurement report is not performed between 2 TRPs, the phase between the reported TRPs cannot be referred to as the TDCP phase, and the phase between the TRPs is referred to as the first phase difference in order to distinguish from the TDCP phase (the phase corresponding to the time domain correlation characteristic). The first phase difference may also be understood as a phase corresponding to a non-time domain correlation property.

In order to facilitate the pre-compensation operation (for eliminating the influence of the frequency synchronization error) of the network side device, besides reporting the TDCP value, the UE needs to report the first phase difference between the TRPs, and how to obtain the first phase difference between the TRPs is described in the related embodiments and will not be repeated here.

Here, the first phase difference and the TDCP phase may be quantized using the same quantization method, and may be quantized using different quantization methods, such as the TDCP phase using 4 bits quantization, the first phase difference between TRP may be quantized using 3 bits quantization, or quantized using 5 bits.

The UE may report the first phase difference between the plurality of TRPs (TRS resource sets with the same QCL parameter or TRS resource sets associated with the same index value or the same resource subgroup) at the current time, and may also report the first phase difference between the plurality of TRPs at each delay value.

4) And reporting one or more delay values, a plurality of TDCP values corresponding to each delay value and a plurality of first phase differences to the network side equipment.

Based on the above 3), the UE may additionally report a delay value, where the delay value may be applicable to all TRS resource sets or CSI resource sets corresponding to TRPs, or may be applicable to TRS resource sets or CSI resource sets corresponding to specific TRPs.

In some embodiments, the measurement comprises a time delay difference;

optionally, the delay difference is a frequency difference of the sub-bands, i.e. a delay difference obtained according to the reporting granularity of the cqt CSI. The network side equipment uses corresponding delay difference to pre-compensate based on each sub-band, or adjusts the CSI reporting granularity according to the corresponding delay difference. Compared with the whole broadband reporting only one time delay difference, the pre-compensation effect after the sub-band reporting is better.

It should be noted that, if the network side device configures more measurement resource ports for the terminal, for example, a single TRP uses at most 128 ports (for example, 4 CSI-RS resources of 32 ports are used to construct a CSI-RS resource of 128 ports), or when multiple TRPs jointly use 128 or 256 ports, K measurement resources need to be extended into K groups of measurement resources (for example, each group contains 2K, 3K, 4K, 8K or even more measurement resources (for example, KP measurement resources), where P is the number of measurement resources contained in each group, for example, P measurement resources jointly construct a larger number of ports, for example, KP antenna ports, and P is greater than or equal to 1). In this case, it is clear how the UE determines which measurement resources are in a group and performs measurement reporting according to a plurality of CSI-RS resources in the group. Such as the UE using a set of measurement resources to determine the PMI reporting amount for a time instance or the UE using a set of measurement resources to determine a higher port number precoding codeword. Thus, as an alternative implementation manner, after receiving a first resource set sent by a network side device, measuring at least one group of resources in the first resource set, and before obtaining a measurement quantity, the method of the present application further includes:

Determining each group of resources in the first set of resources according to first information, wherein the first information comprises one or more of the following:

time domain related parameters;

a resource identifier;

Measuring a configuration sequence;

packet information configured by the network side device.

Specifically, the terminal may determine which resources (CSI-RS resources or TRS resources) are a set according to the time domain related parameters, such as transmission slot information of the time domain related parameters as resources, or slot offset (slotoffset) configuration, etc.

The terminal may determine which resources are a group based on the resource identification ID, e.g., determine that every P resources are a group in order of the resource ID value from small to large.

The terminal may determine which resources are a group based on the measurement configuration order, e.g., determine every P resources as a group in the resource configuration order.

The terminal may determine a plurality of resources within a group based on the packet information configured by the network side device. If the network side equipment configures K groups of resources in a first resource set, each group contains P resources, namely, each group explicitly configures the contained resource ID.

It is of course also possible to determine which resources are a group based on a combination of the above information. For example, the network side device determines the first resources of each group according to the resource ID, and determines other resources in each group as resources with time slot offset smaller than a specific value from the first resources of each group according to the time domain related parameter configuration of the resources, or the network side device explicitly configures the first resources of each group, and determines other resources in each group according to the time domain related parameter configuration of the resources.

Optionally, each set of resources has the same slot offset value or is configured in the same slot.

Optionally, the terminal determines that each of the plurality of resources has a different port index value. If during configuration, port indexes of a group of multiple CSI-RS resources are all 0 to P-1, wherein P is the port number of each CSI-RS resource, and the terminal determines that the multiple CSI-RS resources in the group jointly construct more port numbers, such as 4P antenna ports. If the terminal determines that the first CSI-RS resource in the group maps to port 0 to P-1 at transmission, the second CSI-RS resource maps to port P to 2P-1 at transmission, the third CSI-RS resource maps to port 2P to 3P-1 at transmission, and the fourth CSI-RS resource maps to port 3P to 4P-1 at transmission.

Optionally, the terminal determines that the resources of different groups have the same port index value, that is, the port indexes corresponding to the CSI-RS resources in the first group are 0 to 4P-1, and the port indexes corresponding to the multiple CSI-RS resources in the second group, the third group and the fourth group are also 0 to 4P-1.

In an alternative embodiment, the first information includes time domain related parameters, and accordingly, determining each group of resources in the first resource set according to the first information includes:

determining the resources in the corresponding time slot in the first resource set as a group of resources, or

Determining resources configured with the same time slot offset value in the first resource set as a group of resources;

It should be understood that the terminal determines a plurality of resources within one slot as a group or configures the same slot offset value as a group. Alternatively, the different sets of resources are configured in different time slots, with a predetermined interval, such as 1 time slot or 2 time slots, between each set of resources, wherein the predetermined interval is configured by the network side device.

Or determining the resources with the difference of the configured time slot offset values smaller than a first threshold value in the first resource set as a group of resources. The resources having a slot offset value of 0 or 1 are divided into a group, for example, 2 resources.

Optionally, a time interval between a first resource of the two consecutive sets of resources is greater than or equal to a first preset time slot value. E.g. 1 or 2 time slots apart, where the time interval is configured by the network side device.

Specifically, the first resource is one or more of the following:

The resource with the minimum identification value in each group of resources;

The resource with the largest identification value in each group of resources;

a first configured resource in each set of resources;

the resource with the smallest time slot offset value in each group of resources;

The resources with the largest time slot offset value in each group of resources.

Optionally, the time interval between the last resource in each group of resources and the last resource in the previous group of resources is greater than or equal to a second preset time slot value, or

The time interval between the first resource in each group of resources and the last resource in the previous group of resources is greater than or equal to the third preset time slot value, or

The time interval between the last resource in the two consecutive groups of resources is greater than or equal to the fourth preset time slot value.

When a group includes multiple resources, the multiple resources may jointly form resources of more antenna ports, which are used to determine a port index in the PMI, for example, a precoding matrix has a dimension of v×128, where v represents a number of transmission layers, and 128 represents a number of antenna ports to be transmitted. The number of antenna ports corresponding to the PMI is in one-to-one correspondence with the ports of each group of a plurality of measurement resources, for example, the first resource of each group corresponds to antenna ports 0-31 and is used for determining channel information and precoding weight of the ports 0-31, the second resource corresponds to antenna ports 32-63 and is used for determining channel information and precoding weight of the ports 32-63, the third resource corresponds to antenna ports 64-95 and is used for determining channel information and precoding weight of the ports 64-95, and the fourth resource corresponds to antenna ports 96-127 and is used for determining channel information and precoding weight of the ports 96-127. For another example, the mapping relationship between the CSI-RS resource index or port index and CSI or PMI calculation is determined according to the following method:

Mapping method 1 (1 st resource, 1 st polarization), then (2 nd resource, 1 st polarization), then (K resource, 1 st polarization), then (1 st resource, 2 nd polarization), then (2 nd resource, 2 nd polarization), then (K resource, 2 nd polarization) the order ordering/index within then (K resource, 2 nd polarization) maps onto PMI.

Mapping method 2 (wherein kxn2=n2) in order ordering/indexing:

for polarization 1, (port 1N 2 in resource 1, polarization 1), (port 1N 2 in resource 2, polarization 1), (port 1N 2 in resource K, polarization 1), then (port 2N 2 in resource 1, polarization 1), (port 2N 2 in resource K, polarization 1), then (N1 st N2 port in resource 1, polarization 1), N1 st N2 port in resource 2, polarization 1), polarization 1, (N1 st N2 port, 1 st polarization in the K resource);

Further to polarization 2, (port 1N 2 in resource 1, polarization 2), (port 1N 2 in resource 2, polarization 2) the term (port 1N 2 in resource K, polarization 2) then (port 2N 2 in resource 1, polarization 2), the term (port 2N 2 in resource K, polarization 2), then (port 1N 2 in resource 1, polarization 2), the term (port 2N 1 in resource 2), the term (port 1N 2 in resource 2, polarization 2), the term (PMI 1 in resource 2, polarization 1).

Where N1 and N2 are higher layer signaling configurations, representing the number of antenna ports in the horizontal and vertical directions, n2=n2/K, respectively.

Therefore, in order to determine the PMI, it is necessary to determine which of a plurality of resources in a group is the first resource, which is the second resource, the third resource, and the fourth resource, and thus it is possible to determine which port's channel information and precoding matrix weight according to which resource is determined. In an alternative embodiment, the nth resource of each set of resources is one or more of:

the resource identification values in each group of resources are arranged in a descending order and are arranged in the nth resource;

the resource identification values in each group of resources are arranged in the order from big to small and are arranged in the nth resource;

each group of resources are arranged according to the resource allocation sequence and are arranged in the nth resource;

The resources in each group are arranged in sequence from small to large according to the time slot offset value, and are arranged in the nth resource;

and the resources in each group are arranged in the sequence from the big to the small according to the time slot offset value values, and are arranged in the nth resource.

The measurement reporting method of the embodiment of the application comprises the steps of receiving one or more first resource sets transmitted by network side equipment, wherein the first resource sets are trace reference signal TRS resource sets or channel state information CSI resource sets, then measuring resources in the first resource sets under the condition that the first resource sets transmitted by the network side equipment are received to obtain measurement quantity, wherein the QCL parameters of one part of the first resource sets are the same, associated index values are the same, corresponding resource subgroups are the same or corresponding time resources are different, the QCL parameters of one part of the resources are different, associated index values are different, corresponding resource subgroups are the same or corresponding time resources are the same, thereby determining the corresponding relation between the first resource sets and the TRP or the corresponding relation with different moments, so as to conveniently realize measurement reporting among multiple TRPs, measurement reporting at the same different moments, finally reporting the measurement quantity to the network side equipment, wherein the measurement quantity comprises the TDL parameters, the index values are the same, the corresponding index values are the same or corresponding time resources are different, the measurement quantity is more convenient to realize measurement matrix reporting among the measurement quantity, the measurement quantity is more than the first resource sets, the measurement quantity is more than the measurement quantity is obtained by the measurement quantity, and the measurement quantity is more than the measurement quantity of the first port of the measurement terminal sets, the measurement quantity is transmitted by the network side equipment, and the measurement quantity is more than the corresponding to the measurement quantity of the first port sets, thereby, the auxiliary network side equipment reduces or eliminates the influence of time-frequency synchronization errors or reciprocity errors based on the reported measurement quantity.

Fig. 14 is a schematic flow chart of a measurement reporting method according to an embodiment of the present application, where the method is applied to a network side device, that is, is executed by the network side device. Specifically, the method comprises the following steps:

Step 1401, one or more first resource sets for measurement are sent to the terminal, wherein the first resource sets are tracking reference signal TRS resource sets or channel state information CSI resource sets, and when the first resource sets sent to the terminal are multiple, QCL parameters of a part of the first resource sets are the same, associated index values are the same, corresponding resource subgroups are the same or corresponding time resources are different;

the plurality of first resource sets are configured by the network side device. The TRS resource set comprises a plurality of TRS resources, and the CSI resource set comprises a plurality of CSI-RS resources. The time resources may be time slots, symbols, etc.

The method comprises the steps of determining a corresponding relation between a terminal and TRP or a corresponding relation between the terminal and different time, wherein the QCL parameters of a part of resources in a plurality of first resource sets are the same, associated index values are the same, corresponding resource subgroups are the same or corresponding time resources are different, the QCL parameters of a part of resources are different, associated index values are different, corresponding resource subgroups are different or corresponding time resources are the same, and the purpose is to enable the terminal to determine the corresponding relation between the terminal and the TRP or the corresponding relation between the terminal and different time so as to realize measurement reporting among multiple TRPs and measurement reporting at different time of the same TRP. For example, some first resource sets in the plurality of first resource sets correspond to the same TRP (e.g., determined according to the QCL parameter, a plurality of first resource sets corresponding to the same QCL parameter correspond to the same TRP; e.g., determined according to the index value, a first resource set associated with the same index value corresponds to the same TRP), some first resource sets correspond to different TRPs (e.g., determined according to the QCL parameter, a plurality of first resource sets corresponding to different QCL parameter correspond to different TRPs respectively; e.g., determined according to the index value, a first resource set associated with different index value corresponds to different TRP respectively). For another example, some of the first resource sets corresponding to the same time resource correspond to different TRPs, and some of the first resource sets corresponding to different time resources correspond to the same TRPs; of course, the terminal may determine the corresponding relationship with the TRP or determine the corresponding relationship with different time according to the combination of one or more of the above conditions.

Step 1402, receiving a measurement quantity reported by the terminal, where the measurement quantity includes at least one of a frequency difference, a time delay difference, a phase difference, a TDCP amplitude, and a precoding matrix indication PMI.

Wherein the frequency difference may be represented by a first amplitude, i.e. the frequency difference is a specific value or amplitude, which is used to characterize the frequency difference.

The network side equipment receives the measurement quantity reported by the terminal, and the influence of time-frequency synchronization errors or reciprocity errors can be eliminated based on the reported measurement quantity. For example, the reported measurement quantity is the frequency difference or the phase difference among different TRPs, so that the frequency synchronization error can be eliminated, and if the reported measurement quantity is the time delay difference among different TRPs, the time synchronization error can be eliminated.

In some embodiments, the methods of the present application further comprise:

Note that K represents the number of TRPs, and N represents the number of first resource sets at different times of one TRP.

For the convenience of understanding the above embodiments, reference may be made to the detailed description of the first and second terminal-side examples, which are not repeated herein,

Or configuring K first resource sets for the terminal.

Optionally, in case of configuring K first resource sets for the terminal,

All resources in each of the first resource sets have the same QCL parameters, the resources in a set having QCL parameters that differ between different first resource sets, or

Part of the resources in each of the first resource sets have different QCL parameters, or

Each first resource set is associated with an index value, the index values associated with different first resource sets are different, or

Each first resource set corresponds to one resource subgroup, or each resource subgroup corresponds to one time resource.

For the convenience of understanding the above embodiments, reference may be made to the description of the third to sixth terminal side examples, and the description thereof will be omitted.

After the network side equipment receives the measurement quantity reported by the terminal, the processing for reducing or eliminating the time-frequency synchronization error is performed based on the reported measurement quantity.

When there is a frequency synchronization error between the plurality of TRPs, if receiving is performed at the receiving frequency of one TRP, the channels of other TRPs may be caused to exhibit selectivity in time, i.e. to change rapidly in time. The UE may measure and report at least one of a frequency difference, a phase difference, or a TDCP value by measuring the TRS or CSI-RS. After the network side equipment receives the report of the UE, the error can be reduced or eliminated by the following three modes:

The first mode is that the transmission pre-compensation/pre-processing is carried out according to the report of the UE, and the frequency asynchronous error is eliminated, so that the channel is flattened in time;

The granularity of the precoding matrix is adjusted according to the reporting of the UE, if the feedback period/interval is reduced, the CSI reporting granularity is matched with the current time-varying channel characteristic;

And thirdly, determining service TRP (namely performing TRP selection) according to the report of the UE, for example, selecting TRP with relatively smaller frequency error for CJT transmission.

When there is a time synchronization error between a plurality of TRPs, if receiving is performed at the receiving timing of one TRP, the channels of other TRPs are caused to exhibit selectivity in frequency, that is, to change rapidly in time. The UE may measure and report at least one of a delay difference or a phase difference by measuring the TRS or CSI-RS. After the network side equipment receives the report of the UE, the error can be reduced by the following three modes:

The first mode is that the transmission pre-compensation/pre-processing is carried out according to the report of the UE, the time asynchronous error is eliminated, and the channel is flattened in frequency;

and secondly, adjusting granularity of a precoding matrix according to reporting of the UE, i.e. reducing granularity of a sub-band, namely enabling the granularity of reporting the CSI to be matched with the current frequency channel characteristic.

And thirdly, determining service TRP (namely performing TRP selection) according to the report of the UE, for example, selecting TRP with relatively small time error for CJT transmission.
