Technical Field

[0003] The present disclosure relates to the field of communication technologies, and in particular to a measurement reporting method, apparatus, device, and medium. Background Art

[0004] In current New Radio (NR) systems, when using coherent joint transmission (CJT), in order to reduce the impact of time synchronization error, frequency synchronization error, or reciprocity error on CJT transmission, a measurement and reporting method based on a tracking reference signal (TRS) can be used to assist in error elimination through user equipment (UE) reporting. However, the TRS-based time domain channel properties (TDCP) measurement and reporting method in related technologies cannot be directly applied because TDCP is only used for measurement reporting under a single transmission reception point (TRP) and is not suitable for eliminating time and frequency synchronization errors or reciprocity errors between TRPs. In addition, in measurement reporting based on the Type II Doppler codebook, the network configures a measurement resource set for the terminal to perform precoding matrix index (PMI) measurement reporting. Based on this scenario, if the network configures more measurement resource ports for the terminal, the measurement reporting method based on the Channel State Information Reference Signal (CSI-RS) is subject to time-frequency synchronization errors. In summary, there is no corresponding solution for how to reduce or eliminate the impact of time-frequency synchronization errors or reciprocity errors through measurement reporting based on reference signals.

[0051] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0052] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0053] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0054] In order to facilitate understanding of the solution of the present disclosure, the relevant contents involved in the present disclosure are first introduced.

[0055] In the NR system, TRS is used for time-frequency synchronization tracking. When performing measurement reporting based on TRS, one or more TRS resource sets can be associated with a reporting setting, and each TRS resource set contains multiple TRS resources. In this case, the reporting amount can only be configured as 'none' or 'tdcp', where TDCP reporting is used to address the impact of Doppler frequency deviation on transmission. When performing TDCP reporting, the reporting setting is associated with a non-periodic or periodic resource setting, and the number of TRS resource sets included in the resource setting can be 1, 2 or 3; the UE assumes that all TRS resources in multiple TRS resource sets have the same QCL-Type A / C parameters, and QCL-TypeD parameters (if applicable).

[0056] The measurement reporting method based on TDCP is as follows:

[0057] TRS configuration: The network configures a reporting setting for the UE for TDCP measurement reporting. The reporting device is associated with a channel state information (CSI) resource setting, which contains N TRS resource sets, where N = 1, 2 or 3. For periodic CSI resource settings, the UE assumes that all TRS resources in multiple TRS resource sets have the same QCL-Type A / C parameters, and QCL-Type D parameters (if applicable).

[0058] The TDCP reporting method is as follows:

[0059] The network side configures Y delay values ​​for the UE, where the maximum number of delay values ​​is 4. The UE reports the amplitudes (also called TDCP amplitudes) corresponding to the configured Y delay values. In some embodiments, the UE reports the TDCP phase.

[0060] Specifically, the amplitude quantization method is as follows:

[0061] Use 4 bits for quantization, and the quantization alphabet is 1-2 -(N-q)s , where q = 0, 1, …, 2Q-1, N = 2Q, Q = 4, s = {1 / 4, 1 / 2, 2 / 3, 3 / 4}.

[0062] When the number of delays Y = 1, only the normalized TDCP amplitude of the wideband quantization is reported;

[0063] When the number of delays Y>1, the broadband quantized normalized amplitude and broadband TDCP phase of each delay are reported;

[0064] TDCP phase quantization method (4-bit uniform phase quantization): using the formula Quantify, where: C TDCP =[C1...C Y ] C i ∈{0,1,...,15}

[0065] When using CJT transmission, to reduce the impact of time synchronization error, frequency synchronization error, or reciprocity error on CJT transmission, a TRS-based measurement reporting method can be used to assist in error elimination through UE reporting. However, the TDCP-based measurement reporting method in related technologies cannot be directly applied because TDCP is only used for measurement reporting under a single TRP.

[0066] In addition, in the measurement report based on the Type-II Doppler codebook (also known as the Type-II codebook for predicted PMI, the Type-II codebook indicated by the 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 characteristics of the measurement resource set are periodic or semi-persistent, the measurement resource set contains only one measurement resource; when the time domain transmission characteristics of the measurement resource set are aperiodic, the measurement resource set contains K∈{4,8,12} measurement resources. The K measurement resources can correspond to different time moments.

[0067] If the network-side device configures more measurement resource ports for the terminal, such as a single TRP using up to 128 ports (such as using four 32-port CSI-RS resources to construct a 128-port CSI-RS resource), or multiple TRPs jointly using 128 or 256 ports, the CSI-RS-based measurement reporting method has the problem of time-frequency synchronization error.

[0068] In summary, there is no corresponding solution for how to perform measurement reporting based on reference signals to eliminate the influence of time-frequency synchronization error or reciprocity error.

[0069] In order to solve the above technical problems, the embodiments of the present disclosure provide a measurement reporting method, apparatus, device and medium, wherein the method and apparatus are based on the same application concept. Since the principles of solving the problems by the method and apparatus are similar, the implementation of the apparatus and method can refer to each other, and the repeated parts will not be repeated.

[0070] As shown in Figure 1, it is a flow chart of the measurement reporting method provided by the embodiment of the present disclosure. The method is applied to the terminal, that is, executed by the terminal. Specifically, the method includes:

[0071] Step 101: receiving one or more first resource sets sent by a network-side device, where the first resource set is a tracking reference signal TRS resource set or a channel state information CSI resource set;

[0072] Here, the network-side device configures one or more first resource sets for the terminal and sends them to the terminal.

[0073] The TRS resource set includes multiple TRS resources; the CSI resource set includes multiple CSI-RS resources.

[0074] Step 102: When multiple first resource sets are received from the network side device, the resources in the multiple first resource sets are measured to obtain measurement quantities; wherein, in the multiple first resource sets, a portion of the resources have the same QCL parameters, the same associated index values, the same corresponding resource subgroups, or different corresponding time resources; a portion of the resources have different QCL parameters, different associated index values, different corresponding resource subgroups, or the same corresponding time resources; the measurement quantity is reported to the network side device; wherein the measurement quantity includes at least one of the following: frequency difference; delay difference; phase difference; TDCP amplitude.

[0075] Here, the time resource may be a time slot, a symbol, or the like.

[0076] It should be understood that among the multiple first resource sets, a part of the resources have the same QCL parameters, the same associated index values, the same corresponding resource subgroups or different corresponding time resources. The part of the resources here refers to a part of the first resource sets and all the resources within these first resource sets; and / or, refers to a part of the resources within a certain first resource set.

[0077] Among the multiple 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. The part of the resources here refers to a part of the first resource sets, and the associated index values ​​between these first resource sets are different, the corresponding resource subgroups are different, the corresponding time resources are the same, or the corresponding QCL parameters between these first resource sets are different; and / or, refers to a part of the resources within a certain first resource set.

[0078] Among the multiple first resource sets, some resources have the same QCL parameters, the same associated index values, the same corresponding resource subgroups, or different corresponding time resources; some resources have different QCL parameters, different associated index values, different corresponding resource subgroups, or the same corresponding time resources; the purpose is to determine the correspondence between the first resource set and the TRP, or to determine the correspondence between the first resource set and different moments, so as to realize measurement reporting between multiple TRPs and measurement reporting of the same TRP at different moments. For example, among the multiple first resource sets, some first resource sets correspond to the same TRP (such as determined based on QCL parameters, several first resource sets with the same QCL parameters correspond to the same TRP; such as determined based on index values, first resource sets with the same associated index value correspond to the same TRP), and some first resource sets correspond to different TRPs (such as determined based on QCL parameters, several first resource sets with different QCL parameters correspond to different TRPs respectively; such as determined based on index values, first resource sets with different index values ​​correspond to different TRPs respectively). For another example, some first resource sets corresponding to the same time resources correspond to different TRPs, and some first resource sets corresponding to different time resources correspond to the same TRP; of course, the terminal can determine the correspondence with the TRP, or determine the correspondence with different time moments based on a combination of one or more of the above conditions.

[0079] It should be noted that the frequency difference can be the frequency difference between different TRPs, or the frequency difference at different times of the same TRP; the delay difference can be the delay difference between different TRPs, or the delay difference at different times of the same TRP; the phase difference can be the phase difference between different TRPs, or the phase difference at different times of the same TRP.

[0080] The frequency difference or the time delay difference can be represented by a first amplitude, that is, the frequency difference is a specific value or amplitude, and the value or amplitude is used to represent the frequency difference or the time delay difference.

[0081] Here, the terminal reports a measurement to the network device, specifically at least one of the following: frequency difference, delay difference, phase difference, or TDCP amplitude. Because the measurement reported by the terminal includes measurements between multiple TRPs, the network device can eliminate the effects of time-frequency synchronization errors or reciprocity errors based on the reported measurement. For example, if the reported measurement is the frequency difference or phase difference between different TRPs, frequency synchronization errors can be eliminated; if the reported measurement is the delay difference between different TRPs, time synchronization errors can be eliminated.

[0082] Step 103: When the first resource set sent by the network side device is one, measure at least one group of resources in the first resource set to obtain a measurement value; and report the measurement value to the network side device, where the measurement value at least includes a precoding matrix indicator PMI.

[0083] It should be understood that this step 103 corresponds to a scenario in which the network-side device configures a measurement resource set for the terminal to perform PMI measurement and reporting in measurement reporting based on a Type II Doppler codebook. Here, measuring at least one resource set in the first resource set refers to separately measuring each resource set in the at least one resource set in the first resource set, and obtaining a PMI after measuring each resource set. By measuring at least one resource set in the first resource set, a measurement value is obtained; thereby, the correspondence between each resource set in the first resource set and an antenna port is determined, thereby facilitating measurement reporting for more ports.

[0084] In some embodiments, among the plurality of first resource sets:

[0085] All resources in the (i-1)N+1th first resource set to the i×Nth first resource set have the same QCL parameters, or the (i-1)N+1th first resource set to the i×Nth first resource set correspond to different time resources, where i=1, 2…K, N, K are positive integers greater than or equal to 1; and / or,

[0086] All resources in the jth first resource set, the j+Kth first resource set, ..., the j+(N-1)K first resource sets have the same QCL parameters, or the jth first resource set, the j+Kth first resource set, ..., the j+(N-1)K first resource sets correspond to different time resources, where j=1, 2, ..., K; and / or,

[0087] The (p-1)K+1th to p×Kth first resource sets respectively correspond to the same time resources, or all resources in the same first resource set from the (p-1)K+1th to p×Kth first resource sets have the same QCL parameters, and the QCL parameters of resources in different first resource sets are different, where p=1, 2…N; and / or,

[0088] The qth first resource set, the q+Nth first resource set, ...q+(K-1)N first resource sets respectively correspond to the same time resources, or all resources in the same first resource set in the qth first resource set, the q+Nth first resource set, ...q+(K-1)N first resource sets have the same QCL parameters, and the QCL parameters of resources in different first resource sets are different, where q=1, 2…N.

[0089] Multiple first resource sets that meet the above conditions are configured by the network side device, wherein the xth (such as (p-1)K+1, q, etc.) first resource set is the xth resource set configured by the network side device, or is determined in ascending order according to the configured index value (ID).

[0090] Specifically, based on the limitation of the above-mentioned multiple first resource sets, the association relationship between the first resource set and the TRP, or the association relationship between the first resource set and different time moments can be determined.

[0091] To facilitate understanding of the above embodiment, the following description is given by taking the first resource set as a TRS resource set as an example.

[0092] When used to eliminate frequency desynchronization, the network side device can associate a resource setting in a reporting setting, where the resource setting configures K×N TRS resource sets (i.e., CSI-RS resource sets configured with the parameter trs-Info, corresponding to the high-level parameter NZP-CSI-RS-ResourceSet), where K represents the number of TRPs, and N represents the number of TRS resource sets at different times of a TRP.

[0093] Example 1: A reporting setting is associated with at most 4N TRS resource sets, where N = 1, 2 or 3. The network-side device first configures TRS resource sets for different times of a TRP, and then configures multiple TRS resource sets for other TRPs. According to the configuration order of TRS resource sets, for periodic TRS, the network-side device configures the first TRS resource set to the Nth TRS resource set. All resources in these N TRS resource sets have the same QCL-Type A / C / D parameters. All resources in these N TRS resource sets have the same QCL-Type A / C / D parameters. All resources in these N TRS resource sets have the same QCL-Type A / C / D parameters. All resources in these N TRS resource sets have the same QCL-Type A / C / D parameters. All resources in these N TRS resource sets have the same QCL-Type A / C / D parameters. All resources in these N TRS resource sets have the same QCL-Type A / C / D parameters. N TRS resource sets form a group. All resources in the group have the same QCL parameters. The corresponding QCL parameters of different groups are different. As shown in Figures 2 and 3, here, in Figures 2 and 3, K = 4 and N = 3.

[0094] When performing measurements, the UE determines a frequency difference, a phase difference, or a TDCP value based on multiple TRS resource sets with the same QCL parameters. That is, the UE performs measurements based on multiple TRS resource sets with the same QCL parameters to obtain a frequency difference, a phase difference, or a TDCP value.

[0095] In some embodiments, the TRS resource sets configured by the network side device for multiple TRPs have the same interval in time.

[0096] In order to ensure that the reference time for frequency deviation measurement of each TRP is the same, the network side device can predict the channel information of multiple TRPs at the same time in the future through the UE's report; in some embodiments, the qth TRS resource set, the q+Nth TRS resource set,... the q+(K-1)Nth TRS resource set are sent to the terminal in the same time slot, where q=1, 2...N; as shown in the TRS style in Figure 2, TRS set 1 (the first TRS resource set), TRS set 4 (the fourth TRS resource set), TRS set 7 (the seventh TRS resource set), and TRS set 10 (the tenth TRS resource set) are sent to the terminal in the same time slot.

[0097] It should be understood that Figures 2 and 3 correspond to the (i-1)N+1th first resource set to the i×Nth first resource set configured by the network side device, and all resources in these N first resource sets have the same QCL parameters. For example, all resources in TRS set 1 (the first TRS resource set) to TRS set 3 configured by the network side device for TRP1 (the first TRP) have the same QCL parameters, which are all QCL parameter 1.

[0098] Figures 2 and 3 also correspond to the (i-1)N+1th first resource set to the i×Nth first resource set configured by the network side device, which correspond to different time resources respectively. For example, the TRS set 1 (the first TRS resource set) to TRS set 3 configured by the network side device for TRP1 (the first TRP) are sent on different time resources (such as time slots).

[0099] Figure 2 also corresponds to the qth first resource set, q+Nth first resource set,...q+(K-1)N first resource sets configured by the network side device, which correspond to the same time resources respectively, such as TRS set 1 (first TRS resource set) configured by the network side device for TRP1 (first TRP), TRS set 4 (fourth TRS resource set) configured by the network side device for TRP2 (second TRP), TRS set 7 (seventh TRS resource set) configured by the network side device for TRP3 (third TRP), and TRS set 10 (10th TRS resource set) configured by the network side device for TRP4 (fourth TRP) are sent on the same time resource (such as time slot).

[0100] Figures 2 and 3 also correspond to the qth first resource set, q+Nth first resource set, ...q+(K-1)N first resource sets configured by the network side device. For these K first resource sets, all resources in the same first resource set have the same QCL parameters, and the QCL parameters of resources in different first resource sets are different, that is, the corresponding QCL parameters between different first resource sets are different. For example, all resources of TRS set 1 (first TRS resource set) configured by the network side device for TRP1 (first TRP) have the same QCL parameter 1, all resources of TRS set 4 (fourth TRS resource set) configured by the network side device for TRP2 (second TRP) have the same QCL parameter 2, all resources of TRS set 7 (seventh TRS resource set) configured by the network side device for TRP3 (third TRP) have the same QCL parameter 3, and all resources of TRS set 10 (tenth TRS resource set) configured by the network side device for TRP4 (fourth TRP) have the same QCL parameter 4.

[0101] Example 2: A reporting setting is associated with up to 3K TRS resource sets, where K = 1, 2, 3 or 4. The numbering order of TRS is different from that in Example 1. All resources in the j-th TRS resource set, the j+K-th TRS resource set, and the j+2K-th TRS resource set have the same QCL parameters, j = 1, 2...K, as shown in Figures 4 and 5. Here, in Figures 4 and 5, j = 1, 2, 3, 4; K = 4.

[0102] In some embodiments, the TRS resource sets configured by the network side device for multiple TRPs have the same interval in time.

[0103] In order to ensure that the reference time for frequency offset measurement of each TRP is the same, the network-side device can predict the channel information of multiple TRPs at the same time in the future through the report of the UE; in some embodiments, the (i-1)N+1th first resource set to the i×Nth first resource set are sent to the terminal in the same time slot, where i=1, 2...K. For example, the first TRS resource set to the Nth TRS resource set can be sent in the same time slot, the N+1th TRS resource set to the 2Nth TRS resource set can be sent in the same time slot, and the 2N+1th TRS resource set to the 3Nth TRS resource set can be sent in the same time slot; as in the TRS pattern in Figure 4, TRS set 1 (the first TRS resource set), TRS set 2 (the second TRS resource set), TRS set 3 (the third TRS resource set), and TRS set 4 (the fourth TRS resource set) are sent to the terminal in the same time slot.

[0104] It should be understood that Figures 4 and 5 correspond to the network side device configuring all resources in the j-th first resource set, the j+K-th first resource set, ...j+(N-1)K first resource sets to have the same QCL parameters. For example, all resources in TRS set 1 (the first TRS resource set), TRS set 5 (the fifth TRS resource set) and TRS set 9 (the ninth TRS resource set) configured by the network side device for TRP1 (the first TRP) have the same QCL parameters, which are all QCL parameter 1.

[0105] Figures 4 and 5 also correspond to the network side device configuring the jth first resource set, j+Kth first resource set,...j+(N-1)K first resource sets, which correspond to different time resources respectively. For example, the network side device configures TRS set 1 (the first TRS resource set), TRS set 5 (the fifth TRS resource set), and TRS set 9 (the ninth TRS resource set) for TRP1 (the first TRP) to be sent on different time resources (such as time slots).

[0106] Figure 4 also corresponds to the (p-1)K+1th first resource set to the p×Kth first resource set configured by the network side device, which correspond to the same time resources respectively, such as TRS set 1 (first TRS resource set) configured by the network side device for TRP1 (first TRP), TRS set 2 (second TRS resource set) configured by the network side device for TRP2 (second TRP), TRS set 3 (third TRS resource set) configured by the network side device for TRP3 (third TRP), and TRS set 4 (fourth TRS resource set) configured by the network side device for TRP4 (fourth TRP) are sent on the same time resource (such as time slot).

[0107] Figures 4 and 5 also correspond to the fact that all resources in the same first resource set from the (p-1)K+1th first resource set to the p×Kth first resource set configured by the network side device have the same QCL parameters, and the QCL parameters of the resources are different between different first resource sets, that is, the corresponding QCL parameters between different first resource sets are different, such as all resources of TRS set 1 (first TRS resource set) configured by the network side device for TRP1 (first TRP) have the same QCL parameter 1, all resources of TRS set 2 (second TRS resource set) configured by the network side device for TRP2 (second TRP) have the same QCL parameter 2, all resources of TRS set 3 (third TRS resource set) configured by the network side device for TRP3 (third TRP) have the same QCL parameter 3, and all resources of TRS set 4 (fourth TRS resource set) configured by the network side device for TRP4 (fourth TRP) have the same QCL parameter 4.

[0108] It should be noted that, in addition to the configuration order of the above-mentioned TRS resource sets, the correspondence between the TRS resource set and the TRP or different moments can also be determined based on the index value of the TRS resource set. For example, the values ​​of the TRS sets in Figures 2, 3, 4, and 5 can be arranged in ascending order according to the index value of the TRS resource set. For example, TRS set 1 represents the TRS resource set with the smallest index value among all TRS resource sets associated with a reporting setting, and TRS set 5 represents the fifth TRS resource set whose index values ​​are sorted from small to large among all TRS resource sets associated with a reporting setting. After determining the association between the TRS resource set and the TRP or different moments, the UE will measure the TRS resource set and measure the frequency difference, phase difference, or TDCP value between multiple moments of a TRP.

[0109] When used for eliminating time asynchrony or reciprocity errors, the network-side device may associate a resource setting in a reporting setting, wherein K TRS resource sets are configured in the resource setting, where K represents the number of TRPs.

[0110] Accordingly, in some embodiments:

[0111] (1) All resources within the same first resource set have the same QCL parameters, while resources within different first resource sets have different QCL parameters; that is, the QCL parameters corresponding to the resources within different first resource sets are different. This is illustrated below using Example 3: In Example 3, a reporting setting is associated with up to four TRS resource sets.

[0112] In this example, different TRS resource sets correspond to different QCL-Type A / C / D parameters, corresponding to different TRPs, as shown in Figure 6. This scenario can be used for time synchronization error measurement or reciprocity error measurement. In some embodiments, the symbol or subcarrier positions in each TRS resource set are different. This facilitates transmission of multiple TRPs using different beams.

[0113] In the present disclosure, the QCL-Type A / C / D parameters or QCL parameters corresponding to a resource set are also the QCL-Type A / C / D parameters or QCL parameters corresponding to (all) resources in the resource set.

[0114] Referring to FIG. 6 , the TRS resources in each TRS resource set have the same QCL-Type A / C / D parameters.

[0115] Alternatively, (2) some resources within each of the first resource sets have different QCL parameters;

[0116] In some embodiments, some resources within each of the first resource sets have different QCL parameters, wherein the time resources corresponding to the resources with the same QCL parameters within the same first resource set are the same; or, the same first resource set has resources with different QCL parameters corresponding to the same time resources.

[0117] The following is explained through Example 4: In Example 4, one reporting setting is associated with at most 3 TRS resource sets.

[0118] The TRS resources in each TRS resource set have different QCL-Type A / C / D parameters, that is, one TRS resource set supports the transmission of multiple TRPs; the three TRS resource sets are transmitted in different time slots and can be used to eliminate frequency errors or time errors.

[0119] Case 1: A TRS resource set contains at most 8 TRS resources, occupying 4 or 2 slots, and each slot contains 2 or 4 TRS resources. The transmission patterns are shown in Figures 7 and 8.

[0120] It should be understood that the resources in the first resource set corresponding to Figure 7 have different QCL parameters, wherein the time resources corresponding to the resources with the same QCL parameters in the same first resource set are the same, such as TRS resource 1 and TRS resource 2 have the same QCL parameters, both are QCL parameter 1, and are transmitted in the same time slot n.

[0121] The resources corresponding to the first resource set in Figure 8 have different QCL parameters, wherein the same first resource set has corresponding resources with different QCL parameters at the same time resource, such as TRS resource 1 and TRS resource 2 have the same QCL parameter, both are QCL parameter 1; TRS resource 3 and TRS resource 4 have the same QCL parameter, both 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.

[0122] Case 2: A TRS resource set contains at most 4 TRS resources, occupying 4 or 2 slots, and the transmission patterns are shown in Figures 9 and 10.

[0123] In the transmission modes described in Cases 1 and 2 above, the TRS resource in each time slot can have different QCL-Type A / C / D parameters, or each TRS resource can have different QCL-Type A / C / D parameters. Here, for a TRS resource set occupying four slots, the TRS resources in the first two slots and the TRS resources in the last two slots can also have different QCL-Type A / C / D parameters. Examples are not given one by one.

[0124] Or, (3) the same first resource set is associated with the same index value, and different first resource sets are associated with different index values;

[0125] Here, the index value is used to represent the TRP. The following example 5 illustrates this:

[0126] Example 5: A reporting setting is associated with at most P TRS resource sets, and the same first resource set is associated with the same index value, that is, each TRS resource set is associated with an index value, where the index value is used to represent TRP, and different index values ​​represent different TRPs.

[0127] When performing measurement reporting, the UE measures TRS resource sets with different index values, determines the delay difference, frequency difference or phase difference between TRPs and reports it; the UE measures TRS resource sets with the same index value at different times, determines the frequency difference, phase difference or TDCP value of the same TRP at different times and reports it.

[0128] Alternatively, (4) the same first resource set corresponds to the same resource subgroup, or the same resource subgroup corresponds to the same time resource.

[0129] Here, the same first resource set corresponds to the same resource subgroup, that is, when each first resource set corresponds to a resource subgroup, the resource subgroup is used to represent the TRP. The following is explained with Example 6:

[0130] Example 6: A resource setting explicitly configures K resource subgroups, each resource subgroup corresponds to a TRP (e.g., all TRS resources in a TRS resource subgroup have the same QCL parameters), or a resource setting explicitly configures N resource subgroups, each resource subgroup corresponds to a transmission time (e.g., all TRS resources in a TRS resource subgroup are transmitted within a specific time slot interval);

[0131] When performing measurement reporting, the UE measures the TRS resources within the resource subgroup, determines the delay difference, frequency difference or phase difference between the TRPs and reports it; or, the UE measures based on the TRS resource subgroups at different times, determines the frequency difference, phase difference or TDCP value of the same TRP at different times and reports it.

[0132] In some embodiments, in step 102, resources in the plurality of first resource sets are measured to obtain measurement quantities, including the following A and / or B and / or C and / or D:

[0133] A: measuring resources in multiple first resource sets that have the same QCL parameters or are associated with the same index value or correspond to the same resource subgroup or correspond to different time resources to obtain measurement quantities;

[0134] It should be understood that the resources in multiple first resource sets that meet the above conditions can be resources in several first resource sets with the first resource set as the unit. This can correspond to the situation where the network side device configures multiple first resource sets for a TRP. In this case, the measurement amount is the measurement amount of the same TRP at different times.

[0135] The resources in multiple first resource sets that meet the above conditions can also be partial resources in a certain first resource set. This can correspond to the situation where the network side device configures multiple TRPs in one resource set. In this case, the measurement amount is the measurement amount between different TRPs.

[0136] In some embodiments, A specifically includes:

[0137] Selecting one or more resources as reference resources from the plurality of first resource sets, which have the same QCL parameters or are associated with the same index value or correspond to the same resource subgroup or correspond to different time resources;

[0138] The reference resource and resources in multiple first resource sets, which have the same QCL parameters or are associated with the same index value or correspond to the same resource subgroup or correspond to different time resources, except the reference resource, are measured to obtain a measurement value.

[0139] Here, the measurement quantity refers to the measurement quantity between the other resource and the reference resource. For example, when the measurement quantity is frequency difference, it specifically refers to the frequency difference between the other resource and the reference resource; when the measurement quantity is delay difference, it specifically refers to the delay difference between the other resource and the reference resource; when the measurement quantity is phase difference, it specifically refers to the phase difference between the other resource and the reference resource.

[0140] B: measuring resources in the first resource sets associated with the same index value or corresponding to the same resource subgroup or corresponding to different time resources in the plurality of first resource sets to obtain measurement quantities;

[0141] It should be understood that the resource sets that meet the above conditions in multiple first resource sets correspond to the situation where the network side device configures multiple first resource sets for one TRP. In this case, the measurement amount is the measurement amount of the same TRP at different times.

[0142] In some embodiments, B specifically includes:

[0143] Selecting one or more first resource sets as reference resource sets from the plurality of first resource sets, the first resource sets associated with the same index value or corresponding to the same resource subgroup or corresponding to different time resources;

[0144] The resources in the reference resource set and resources in other resource sets except the reference resource set in multiple first resource sets, which are associated with the same index value or correspond to the same resource subgroup or correspond to different time resources, are measured to obtain measurement quantities.

[0145] C: measuring resources in multiple first resource sets that 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;

[0146] It should be understood that the resources that meet the above conditions in multiple first resource sets can be measured in units of first resource sets. For example, all resources in each of several first resource sets have the same QCL parameters, but the corresponding QCL parameters vary between different first resource sets. In this case, the measurement quantity is the measurement quantity between different TRPs.

[0147] The resources in multiple first resource sets that meet the above conditions can also be partial resources in a first resource set. This can correspond to the situation where the network side device configures multiple TRPs in one resource set. In this case, the measurement amount is the measurement amount between different TRPs.

[0148] In some embodiments, C specifically includes:

[0149] Selecting one or more resources as reference 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;

[0150] The reference resource and other resources in multiple first resource sets, except the reference resource, having different QCL parameters or associated with different index values ​​or corresponding to different resource subgroups or corresponding to the same time resources are measured to obtain measurement quantities.

[0151] D: measuring resources in the first resource sets associated with different index values ​​or corresponding to different resource subgroups or corresponding to the same time resources in the plurality of first resource sets to obtain measurement quantities;

[0152] It should be understood that the resource sets that meet the above conditions in multiple first resource sets correspond to the situation where the network side device allocates different first resource sets to different TRPs. In this case, the measurement amount is the measurement amount between different TRPs.

[0153] In some embodiments, D specifically includes:

[0154] Selecting one or more resources as reference resources from a plurality of first resource sets, which are associated with different index values ​​or correspond to different resource subgroups or correspond to the same time resources;

[0155] The reference resource set and other resources in the plurality of first resource sets, associated with different index values ​​or corresponding to different resource subgroups or corresponding to the same time resources, except the reference resource, are measured to obtain a measurement value.

[0156] In some embodiments, the reference first resource set is the first resource set with the smallest index value.

[0157] In some embodiments, the multiple reference first resource sets include multiple first resource sets where burst transmission (eg, TRS burst) occurs earliest.

[0158] For ease of understanding, the following example is used to illustrate:

[0159] Assume that the network side device configures 8 TRS resource sets for the UE, and 4 TRPs serve the UE. Therefore, the number of TRS resource sets corresponding to each TRP is 2. The TRS resource sets (hereinafter referred to as TRS) are numbered as follows:

[0160] TRP 1: TRS 1, TRS 8;

[0161] TRP 2: TRS 2, TRS 3;

[0162] TRP 3: TRS 9, TRS 11;

[0163] TRP 4: TRS 4, TRS 6;

[0164] 1) Taking TRS1 as a reference, the UE calculates and reports measurement quantities based on other TRSs and TRS1.

[0165] 2) Taking TRS1, 2, 9, and 4 as references, the UE reports the measurement values ​​between other TRSs and these reference TRSs.

[0166] In some embodiments, the method of the present disclosure further comprises:

[0167] determining a quantification range of the measured quantity;

[0168] quantizing the measurement quantity within the quantization range to obtain a quantized measurement quantity;

[0169] Accordingly, in step 102, reporting the measurement value to the network-side device includes:

[0170] Report the quantized measurement amount to the network side device.

[0171] After the measurement quantity is quantified on the terminal side, it is reported to the network side device, which can save resources occupied by data transmission.

[0172] In some embodiments, the measurement quantity includes a frequency difference or a delay difference; and determining a quantization range of the measurement quantity includes:

[0173] Determining a phase difference corresponding to the measurement quantity;

[0174] Performing modulo 2π processing on the phase difference corresponding to the measurement quantity to obtain a processing result; wherein the processing result is a remainder obtained by performing modulo 2π calculation on the phase difference corresponding to the measurement quantity.

[0175] The quantization range of the measurement quantity is determined according to the processing result.

[0176] Here, considering that the phase difference corresponding to the frequency difference remains unchanged after modulo 2π processing, it is not necessary to report all frequency differences. Only the frequency differences corresponding to the phase difference within the 2π range are selected for reporting. The specific quantization method is related to the subcarrier spacing. This situation can be used by the network side equipment to perform pre-compensation / pre-processing based on the UE's report, eliminating frequency synchronization errors and making the channel flat in time.

[0177] Assume that the frequency is f, and the phase corresponding to a specific delay t is ej2πft.

[0178] Considering that the phase difference corresponding to the delay difference remains unchanged after modulo 2π processing, it is not necessary to report all delay differences. Only the delay differences corresponding to the phase difference within the 2π range are selected for reporting. The specific quantization method is related to the subcarrier spacing. This situation can be used by network-side equipment to perform pre-compensation / pre-processing based on the UE's report to eliminate time synchronization errors.

[0179] Assuming that the frequency of a subcarrier is fi, the phase corresponding to the specific delay difference τ is

[0180] In some embodiments, the measurement quantity includes a frequency difference or a delay difference; and quantizing the measurement quantity within the quantization range to obtain the quantized measurement quantity includes:

[0181] determining a multiple value and a remainder of the measured quantity relative to the quantization range;

[0182] quantizing the remainder within the quantization range to obtain a quantized value;

[0183] Accordingly, in step 102, reporting the quantized measurement value to the network-side device includes:

[0184] Report the multiple value and the quantization value to the network side device.

[0185] Specifically, the measurement quantity includes a frequency difference; determining a first multiple value and a first remainder of the frequency difference relative to the quantization range; quantizing the remainder within the quantization range to obtain a first value;

[0186] When the absolute value of the frequency difference is considered, that is, when the quantization value is not modulo 2π, the frequency difference can be reported in two parts. First, the quantization range of the frequency difference is determined (for example, the maximum quantization range determined by the subcarrier spacing or center frequency or high-level parameters configured on the network side); then, the UE calculates the first multiple value and the first remainder of the frequency difference relative to the maximum frequency value in the quantization range; finally, the UE reports the first multiple value as the first part, and quantizes the remainder within the quantization range to obtain a first value, which is reported as the second part.

[0187] For example, the maximum quantization range determined according to the subcarrier spacing or the center frequency is 0-400 Hz; if the measured frequency difference is 500 Hz, the UE divides 500 Hz by 400 Hz, and the quotient is 1, and the remainder is 100 Hz. The UE determines that the first part of the reported value is 1, and the second part of the reported value is 100 Hz, which is the quantized value after quantization in the range of [0,400].

[0188] Accordingly, the above step of reporting the quantized frequency difference to the network side device includes:

[0189] Report the first multiple value and the first value to the network side device.

[0190] The above two-step quantization method can further save the resources occupied by data transmission.

[0191] Specifically, the measurement amount includes a delay difference; determining a second multiple value and a second remainder of the delay difference relative to the quantization range;

[0192] quantizing the second remainder within the quantization range to obtain a second value;

[0193] When the absolute value of the delay difference is considered, that is, when the quantization value is not modulo 2π, the frequency difference can be reported in two parts. First, the quantization range of the delay difference is determined (for example, the maximum quantized delay difference value determined based on the subcarrier spacing mentioned above); then, the UE calculates the second multiple value and the second remainder of the delay difference relative to the maximum delay difference value in the quantization range; finally, the UE reports the second multiple value as the first part, and quantizes the second remainder within the quantization range to obtain a second value, which is reported as the second part.

[0194] For example, if the maximum quantization range determined by the subcarrier spacing is 2778ns, and the measured delay difference is 4000ns, the UE divides 4000ns by 2778ns, resulting in a quotient of 1 and a remainder of 1222ns. The UE then determines that the first reported value is 1 and the second reported value is 1222ns, which are quantized values ​​quantized within the range of [0, 2778ns]. Accordingly, the above step of reporting the quantized delay difference to the network-side device includes reporting the second multiple value and the second value to the network-side device.

[0195] The above two-step quantization method can further save the resources occupied by data transmission.

[0196] In one embodiment, the measurement quantity includes a frequency difference; and determining a quantization range of the frequency difference includes at least one of the following:

[0197] ① Determine the quantization range of the frequency difference according to the subcarrier spacing;

[0198] Assuming that the delay value is in time slots and the minimum delay value is 1 time slot, then:

[0199] Taking 15kHz subcarrier spacing as an example, the time length corresponding to each time slot is 1ms. In this case, the frequency difference can be quantized within 0-1000Hz (corresponding to 1 / 1ms);

[0200] For a 30kHz subcarrier spacing, each time slot corresponds to a time length of 0.5ms, so the frequency difference is quantized within 0-2000Hz;

[0201] For a 60kHz subcarrier spacing, the time length corresponding to each time slot is 0.25ms, and the frequency difference is quantized within 0-4000Hz.

[0202] Specifically, a uniform quantization method may be used within a certain quantization range, such as performing quantization at intervals of 50 Hz within a range of [0, 2000 Hz].

[0203] ② Determine the quantization range of the frequency difference according to the center frequency, where the center frequency is the current center frequency, the center frequency configured on the network side, or a predefined center frequency;

[0204] If the frequency difference is used for TRP selection (for example, selecting a TRP with a relatively small frequency error), the selected TRP is transmitted through CJT, which can reduce or eliminate the frequency error. In this case, the network-side equipment is more concerned with the absolute range of the frequency difference. Therefore, the quantization value cannot be modulo 2π. In this case, the quantization range can be determined based on the center frequency.

[0205] Case 1: The quantization range of the frequency difference is related to the current center frequency, such as different center frequencies correspond to different quantization ranges of the frequency difference. For example, in some embodiments, it is related to the maximum frequency deviation index of the device. For example, at 6 GHz, the maximum frequency deviation is 0.1 ppm, and the corresponding maximum frequency difference is 600 Hz, that is, the quantization range of the frequency difference is 0-600 Hz; similarly, at 4 GHz, the corresponding maximum frequency difference is 400 Hz, that is, the quantization range of the frequency difference is 0-400 Hz.

[0206] Case 2: The frequency difference quantization range is related to a specific center frequency (network-configured or predefined). For example, the same frequency difference quantization range is used for all center frequencies. The quantization range can be determined based on the maximum center frequency, such as the maximum frequency range of 6 GHz (or 7.125 GHz). If the maximum frequency deviation is 0.05 ppm, the frequency difference quantization range is 0-0.05 ppm*6 GHz, or 0-300 Hz.

[0207] ③ Determine the quantization range of the frequency difference according to the high-level parameters configured on the network side.

[0208] In some embodiments, the measured quantity includes a delay difference, and determining a quantization range of the delay difference includes at least one of the following:

[0209] ① Determine the quantization range of the delay difference according to the subcarrier spacing;

[0210] Taking 15kHz subcarrier spacing as an example, if the minimum reporting granularity of the delay difference is 1RB, the frequency interval corresponding to each RB is 15kHz×12=180kHz. In this case, the delay difference is quantized within 0 to 1 / 180kHz=5556ns;

[0211] Taking 15 kHz subcarrier spacing as an example, if the minimum reporting granularity of the delay difference is 32 RB, the frequency interval corresponding to each 32 RB is 15 kHz × 12 × 32 = 5760 kHz. In this case, the delay difference is quantized within 0 to 1 / 5760 kHz = 174 ns.

[0212] Taking 30kHz subcarrier spacing as an example, if the minimum granularity of delay difference reporting is 1RB, the frequency interval corresponding to each RB is 30kHz×12=360kHz. In this case, the delay difference is quantized within 0 to 1 / 360kHz=2778ns.

[0213] Taking 30kHz subcarrier spacing as an example, if the minimum granularity of delay difference reporting is 4RB, the frequency interval corresponding to every 4 RB is 30kHz×12×4=1440kHz. In this case, the delay difference is quantized within 0~1 / 1440kHz=694ns.

[0214] Specifically, a uniform quantization method may be used within a certain quantization range, such as performing quantization within a range of [0, 5556 ns] at intervals of 100 ns.

[0215] ② Determine the quantization range of the delay difference based on the reporting granularity of the delay difference.

[0216] Here, the measurement quantity includes the frequency difference. In some embodiments, the frequency difference is the sub-band frequency difference, i.e., the frequency difference obtained according to the CJT CSI reporting granularity. The network-side device performs pre-compensation based on the frequency difference of each sub-band (to reduce or eliminate the impact of frequency synchronization error) or adjusts the CSI reporting granularity based on the corresponding frequency difference. Compared with reporting only a single frequency difference for the entire broadband, the pre-compensation effect after sub-band reporting is better.

[0217] In some embodiments, the measured quantity includes a delay difference. In some embodiments, the delay difference is a subband frequency difference, i.e., a delay difference obtained according to the CJT CSI reporting granularity. The network-side device performs pre-compensation based on the corresponding delay difference for each subband, or adjusts the CSI reporting granularity based on the corresponding delay difference. Compared with reporting only a single delay difference for the entire broadband, pre-compensation after sub-band reporting is more effective.

[0218] In some embodiments, the delay difference is reported according to the phase change granularity corresponding to the delay. This is illustrated by an example: assuming that the phase difference change introduced by the delay difference within four resource blocks (RBs) is less than a specific radian (or a specific threshold, such as π / 2, where the threshold is configured by a higher-layer parameter or reported by the UE), the UE reports the delay difference corresponding to every four RBs, assuming that the channels within the four RBs can use the same delay difference compensation.

[0219] The delay mentioned above is different from the delay mentioned above. It refers to the propagation delay between multiple TRPs, multipath delay, and any inherent delay. For example, it can be smaller than the CP length or slightly larger. The delay in frequency synchronization error elimination, on the other hand, refers to a relatively long period of time, such as four or ten time slots.

[0220] In some embodiments, the measurement quantity includes a delay difference; specifically, the UE determines the first phase difference based on two TRS resource sets with the same QCL parameters, or based on two TRS resource sets with different QCL parameters.

[0221] The first phase difference determined based on two TRS resource sets with the same QCL parameters is the phase difference of the same TRP at two different times; the first phase difference determined based on two TRS resource sets with different QCL parameters is the phase difference between two TRPs.

[0222] In some embodiments, the UE performs measurements based on one or more reference TRS resource sets, or based on one or more CSI-RS related resource units (such as CSI-RS resource ports, CSI-RS resources, CSI-RS resource sets), and accordingly, the UE reports the phase difference between different TRS resource sets and the reference TRS resource set, or reports the phase difference between the CSI-RS related resource unit and the reference CSI-RS related resource unit.

[0223] The following description takes TRS resource collection as an example.

[0224] The reference TRS resource set can be a TRS resource set with the smallest index value among all TRS resource sets associated with a reporting setting, or it can be multiple TRS resource sets where the earliest TRS burst transmission occurs. Each TRP defines a reference TRS resource set.

[0225] Assume that the network side device configures 8 TRS resource sets for the UE, and 4 TRPs serve the UE. Therefore, the number of TRS resource sets corresponding to each TRP is 2. The TRS resource sets (hereinafter referred to as TRS) are numbered as follows:

[0226] TRP 1: TRS 1, TRS 8;

[0227] TRP 2: TRS 2, TRS 3;

[0228] TRP 3: TRS 9, TRS 11;

[0229] TRP 4: TRS 4, TRS 6;

[0230] 1) With TRS1 as a reference, the UE calculates and reports the phase difference between other TRSs and TRS1. Since the phase difference between TRS1 and TRS1 is 0, no reporting is required.

[0231] 2) Taking TRS1, 2, 9, and 4 as references, the UE reports the phase differences between other TRSs and these reference TRSs.

[0232] Accordingly, in step 102, reporting the measurement value to the network-side device includes at least one of the following:

[0233] 1) reporting a plurality of first phase differences to the network-side device, wherein one delay value corresponds to one or more first phase differences, the delay value being configured by the network-side device, and the delay value being a time interval corresponding to the reported measurement value;

[0234] Specifically, the delay value represents the time interval corresponding to the two first phase differences, or when the first phase difference is the first phase difference, the delay value represents the time interval between the moment corresponding to the first phase difference and the reference moment.

[0235] Here, it is assumed that the network-side device is configured with 6 TRS resource sets, TRS resource set 1 to TRS resource set 6, corresponding to 3 TRPs respectively, where TRS resource set 1 and TRS resource set 2 have QCL parameter 1, TRS resource set 3 and TRS resource set 4 have QCL parameter 2, and TRS resource set 5 and TRS resource set 6 have QCL parameter 3;

[0236] One case is that the network-side device configures a delay value that is applicable to all TRPs. For example, if the delay value is 5 slots, the UE can measure TRS resource set 1 and TRS resource set 2 with QCL parameters or the same index value or the same resource subgroup, respectively. The measurement interval between TRS resource set 1 and TRS resource set 2 is 5 slots. After that, the difference between the two phase values ​​is calculated to obtain the first phase difference and report it. Similarly, the first phase differences between other TRS resource sets are obtained according to the above method and then reported. In this way, one delay value corresponds to multiple first phase differences.

[0237] Another situation is that the network-side device configures multiple delay values, and each delay value is only applicable to some TRPs. For example, if the network-side device configures three delay values, namely 2 slots, 3 slots, and 4 slots, 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 in the same resource subgroup at intervals of 2 slots, obtains a first phase difference and reports it; the UE measures TRS resource set 3 and TRS resource set 4 (corresponding to one TRP) with QCL parameters or the same index value or in the same resource subgroup at intervals of 3 slots, obtains a first phase difference and reports it; the UE measures TRS resource set 5 and TRS resource set 6 (corresponding to one TRP) with QCL parameters or the same index value or in the same resource subgroup at intervals of 4 slots, obtains a first phase difference and reports it; in this way, one delay value corresponds to one first phase difference.

[0238] 2) reporting multiple delay values ​​and at least two first phase differences corresponding to each delay value to the network side device, where the number of first phase differences corresponding to each delay value is the same;

[0239] The following is an example eight:

[0240] Example 8: The network-side device uses 3 TRPs to perform CJT transmission for the UE. The UE reports 2 delay values. Taking the TRS resource set corresponding to the first TRP that sends TRS earliest as a reference, the UE reports the phase difference between each TRP and the reference TRP (the first TRP that sends TRS earliest) under each delay value. In this case, even if the time selectivity of multiple TRPs is different, the UE needs to jointly determine a set of delay values ​​based on the time domain channel changes of each TRP. See Figure 11. The number of phase differences corresponding to each delay value is the same.

[0241] When a specific TRP is used as a reference to calculate the phase difference, the phase difference of the TRP at different delay values ​​is only caused by Doppler frequency shift, etc., rather than by clock frequency deviation. When the phase difference changes slightly, the phase value of the reference TRP (or reference TRS resource set) at different delay values ​​may not be reported, see Figure 12.

[0242] 3) reporting a plurality of delay values ​​and at least two first phase differences corresponding to each of the delay values ​​to the network-side device, wherein the number of first phase differences corresponding to each of the delay values ​​is different;

[0243] Under this reporting scheme, not all TRPs report the phase difference under each delay value. For example, if the frequency deviation of a certain TRP is small, the phase difference under some delay values ​​may not be reported.

[0244] Example 9, as shown in Figure 13, takes TRP 1 at the reference time as a reference, and other TRPs are received according to the receiving frequency of TRP 1. The phase difference of TRP 1 at different delay values ​​changes relatively little, so at some delay values, the phase difference of TRP1 may not be reported.

[0245] 4) Reporting multiple delay values ​​and a precoding matrix consisting of at least two first phase differences corresponding to each delay value to the network side device.

[0246] The terminal can obtain multiple first phase differences based on TRS resource sets or CSI-RS related resource units, and then quantize the multiple first phase differences according to a codebook to obtain a precoding matrix. As shown in Figure 11, the UE quantizes the first phase difference using a 6*1 vector (codebook) or two 3*1 vectors (codebooks).

[0247] In some embodiments, the measurement quantity includes a TDCP value;

[0248] When reporting TDCP, the UE can report the TDCP value of the channel corresponding to the same TRP between two time moments (such as two first resource sets with the same QCL parameters but different corresponding time resources), and can also select one TRP (such as a TRS resource set) as a reference. The UE reports the TDCP values ​​of all TRPs under multiple delay values ​​and the reference TRP.

[0249] Assume that the network side device configures 8 TRS resource sets for the UE, and 4 TRPs serve the UE. Therefore, the number of TRS resource sets corresponding to each TRP is 2. The TRS resource sets (hereinafter referred to as TRS) are numbered as follows:

[0250] TRP 1: TRS 1, TRS 8;

[0251] TRP 2: TRS 2, TRS 3;

[0252] TRP 3: TRS 9, TRS 11;

[0253] TRP 4: TRS 4, TRS 6;

[0254] The reported TDCP value can be:

[0255] 1) With TRS1 as a reference, the UE calculates and reports the TDCP values ​​for other TRSs and TRS1 respectively. Since the TDCP value between TRS1 and TRS1 is 0, it does not need to be reported. The UE only needs to report 7 TDCP values ​​(including TDCP amplitude and TDCP phase);

[0256] 2) Taking TRS1, 2, 9, and 4 as references, the UE reports the TDCP values ​​between other TRSs and these reference TRSs;

[0257] 3) The UE reports the TDCP amplitude values ​​with reference to TRS1, 2, 9, and 4 respectively, and reports the TDCP phase values ​​between other TRSs and TRS1 with reference to TRS1.

[0258] Accordingly, in step 102, reporting the measurement value to the network-side device includes at least one of the following:

[0259] 1) reporting multiple TDCP values ​​to the network side device, where one delay value corresponds to one or more TDCP values, the delay value is configured by the network side device, and the delay value is the time interval corresponding to the reported measurement value;

[0260] 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 two measurement quantities.

[0261] Assume that the network-side device is configured with six TRS resource sets, TRS resource set 1 to TRS resource set 6, corresponding to three TRPs respectively. TRS resource set 1 and TRS resource set 2 have QCL parameter 1, TRS resource set 3 and TRS resource set 4 have QCL parameter 2, and TRS resource set 5 and TRS resource set 6 have QCL parameter 3.

[0262] One situation is that the network side device configures a delay value, which can be applicable to all TRPs. For example, if the delay value is 5 slots, the UE can measure TRS resource set 1 and TRS resource set 2 with QCL parameters or the same index value or in the same resource subgroup at intervals of 5 slots, obtain a TDCP value (such as TDCP amplitude) and report it; the UE measures TRS resource set 3 and TRS resource set 4 with the same QCL parameters or the same index value or in the same subgroup at intervals of 5 slots, obtain a TDCP value (such as TDCP amplitude) and report it; the UE measures TRS resource set 5 and TRS resource set 6 with the same QCL parameters or the same index value or in the same subgroup at intervals of 5 slots, obtain a TDCP value (such as TDCP amplitude) and report it; in this way, one delay value corresponds to multiple TDCP values.

[0263] Another situation is that the network-side device configures multiple delay values, and each delay value is only applicable to some TRPs. For example, if the network-side device configures three delay values, namely 2 slots, 3 slots, and 4 slots, 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 in the same resource subgroup at intervals of 2 slots, obtains a TDCP value (such as a TDCP amplitude), and reports it; the UE measures TRS resource set 3 and TRS resource set 4 (corresponding to one TRP) with QCL parameters or the same index value or in the same resource subgroup at intervals of 3 slots, obtains a TDCP value (such as a TDCP amplitude), and reports it; the UE measures TRS resource set 5 and TRS resource set 6 (corresponding to one TRP) with QCL parameters or the same index value or in the same resource subgroup at intervals of 4 slots, obtains a TDCP value (such as a TDCP amplitude), and reports it; in this way, one delay value corresponds to one TDCP value.

[0264] When the delay value corresponding to each TRP exceeds 1, the UE will also report the TDCP phase.

[0265] 2) reporting one or more delay values ​​and multiple TDCP values ​​corresponding to each delay value to the network side device;

[0266] Since the channel time-varying characteristics of multiple TRPs are different, the UE can also report the delay value. One delay value can correspond to multiple TDCP values ​​(TDCP amplitude and / or TDCP phase). One delay value can be used for multiple TRPs or only for a specific TRP.

[0267] In some embodiments, when the network side configures K×N TRS resource sets, the UE is associated with 2K TRS resource sets for one delay value, or is associated with only 2 TRS resource sets.

[0268] 3) reporting multiple TDCP values ​​and multiple first phase differences to the network side device;

[0269] If TDCP measurement reporting is not performed between two TRPs, the phase between the reported TRPs cannot be called the TDCP phase. To distinguish it from the TDCP phase (the phase corresponding to the time-domain correlation characteristic), the phase between the TRPs is called the first phase difference. The first phase difference can also be understood as the phase corresponding to the non-time-domain correlation characteristic.

[0270] In order to facilitate the network side equipment to perform pre-compensation operations (to eliminate the impact of frequency synchronization errors), in addition to reporting the TDCP value, the UE also needs to report the first phase difference between TRPs. For specific instructions on how to obtain the first phase difference between TRPs, please refer to the relevant embodiment section and will not be repeated here.

[0271] Here, the first phase difference and the TDCP phase can be quantized using the same quantization method, or can be quantized using different quantization methods, such as the TDCP phase using 4-bit quantization, the first phase difference between TRPs using 3-bit quantization, or using 5-bit quantization.

[0272] The UE can report the first phase difference between multiple TRPs (TRS resource sets with the same QCL parameters, or TRS resource sets associated with the same index value or the same resource subgroup) at the current moment, and can also report the first phase difference between multiple TRPs at each delay value.

[0273] 4) Reporting one or more delay values, multiple TDCP values ​​corresponding to each delay value, and multiple first phase differences to the network side device.

[0274] On the basis of the above 3), the UE may also additionally report a delay value, which may be applicable to the TRS resource set or CSI resource set corresponding to all TRPs, or to the TRS resource set or CSI resource set corresponding to a specific TRP.

[0275] In some embodiments, the measurement quantity includes a delay difference;

[0276] In some embodiments, the delay difference is the frequency difference of the subbands, that is, the delay difference obtained according to the CJT CSI reporting granularity. The network-side device uses the corresponding delay difference for each subband for pre-compensation or adjusts the CSI reporting granularity based on the corresponding delay difference. Compared with reporting only a single delay difference for the entire broadband, pre-compensation after sub-band reporting is more effective.

[0277] In some embodiments, the delay difference is reported according to the phase change granularity corresponding to the delay. This is illustrated by an example: assuming that the phase difference change introduced by the delay difference within four resource blocks (RBs) is less than a specific radian (or a specific threshold, such as π / 2, where the threshold is configured by a higher-layer parameter or reported by the UE), the UE reports the delay difference corresponding to every four RBs, assuming that the channels within the four RBs can use the same delay difference compensation.

[0278] The delay mentioned above is different from the delay mentioned above. It refers to the propagation delay between multiple TRPs, multipath delay, and any inherent delay. For example, it can be smaller than the CP length or slightly larger. The delay in frequency synchronization error elimination, on the other hand, refers to a relatively long period of time, such as four or ten time slots.

[0279] It should be noted that if the network-side device configures more measurement resource ports for the terminal, such as a single TRP uses up to 128 ports (such as using four 32-port CSI-RS resources to construct a 128-port CSI-RS resource), or multiple TRPs jointly use 128 or 256 ports, then the K measurement resources need to be expanded into K groups of measurement resources, such as each group containing 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, such as P measurement resources jointly construct more ports, such as KP antenna ports, P is greater than or equal to 1). In this case, it is necessary to clarify how the UE determines which measurement resources form a group and performs measurement reporting based on multiple CSI-RS resources in a group. For example, the UE uses a group of measurement resources to determine the PMI reporting amount at a moment, or the UE uses a group of measurement resources to determine a precoding codeword with a higher number of ports. Therefore, in some embodiments, after receiving a first resource set sent by a network-side device, and before measuring at least one group of resources in the first resource set and obtaining a measurement value, the method of the present disclosure further includes:

[0280] In the case where there is only one first resource set, each group of resources in the first resource set is determined according to first information; wherein the first information includes one or more of the following:

[0281] Time domain related parameters;

[0282] Resource identification;

[0283] Measurement configuration sequence;

[0284] Grouping information configured by network-side devices.

[0285] Specifically, the terminal may determine which resources (CSI-RS resources or TRS resources) are grouped together based on time domain related parameters, such as the time domain related parameters being transmission time slot information of the resources, or time slot offset configuration.

[0286] The terminal may determine which resources form a group according to the resource identification ID; for example, determine that each P resources form a group according to the order of resource ID values ​​from small to large.

[0287] The terminal may determine which resources form a group according to the measurement configuration order; for example, determine that every P resources form a group according to the resource configuration order.

[0288] The terminal can determine multiple resources within a group based on the grouping information configured by the network side device. For example, the network side device configures K groups of resources in a first resource set, each group contains P resources, that is, each group explicitly configures the resource IDs contained therein.

[0289] Of course, it's also possible to determine which resources form a group based on a combination of the above information. For example, the network device can determine the first resource in each group based on the resource ID, and then determine the remaining resources in each group based on the resource's time-domain-related parameter configuration: resources with a time slot offset less than a specified value from the first resource in each group. Alternatively, the network device can explicitly configure the first resource in each group and then determine the remaining resources in each group based on the resource's time-domain-related parameter configuration.

[0290] In some embodiments, each group of resources has the same time slot offset value or is configured in the same time slot.

[0291] In some embodiments, the terminal determines that each group of multiple resources has a different port index value. For example, during configuration, the port indexes of a group of multiple CSI-RS resources are all 0 to P-1, where P is the number of ports of each CSI-RS resource. The terminal determines that the multiple CSI-RS resources in a group jointly construct a larger number of ports, such as constructing 4P antenna ports. For example, the terminal determines that the first CSI-RS resource in a group is mapped to ports 0 to P-1 during transmission, the second CSI-RS resource is mapped to ports P to 2P-1 during transmission, the third CSI-RS resource is mapped to ports 2P to 3P-1 during transmission, and the fourth CSI-RS resource is mapped to ports 3P to 4P-1 during transmission.

[0292] In some embodiments, the terminal determines that different groups of resources have the same port index value, that is, the port index corresponding to the CSI-RS resources in the first group is 0 to 4P-1, and the port index corresponding to the multiple CSI-RS resources in the second group, the third group to the fourth group is also 0 to 4P-1.

[0293] In some embodiments, the first information includes time domain related parameters, and the time domain related parameters include transmission time slot information or time slot offset configuration of resources. Accordingly, when there is only one first resource set, determining each group of resources in the first resource set according to the first information includes:

[0294] Determine the resources in the first resource set corresponding to a time slot as a group of resources; or,

[0295] Determining resources in the first resource set configured with the same time slot offset value as a group of resources;

[0296] It should be understood that the terminal determines that multiple resources within a time slot are grouped, or that resources configured with the same time slot offset value are grouped. In some embodiments, different groups of resources are configured in different time slots, and there is a predetermined interval between each group of resources, such as one time slot or two time slots, where the predetermined interval is configured by the network-side device.

[0297] Alternatively, resources in the first resource set whose configured time slot offset values ​​differ by less than a first threshold are determined as a group of resources. For example, resources whose time slot offset values ​​differ by a value of 0 or 1 are grouped together.

[0298] In some embodiments, the time interval between the first resources in two consecutive groups of resources is greater than or equal to a first preset time slot value, such as 1 or 2 time slots, where the time interval is configured by the network side device.

[0299] Specifically, the first resource is one or more of the following:

[0300] The resource with the smallest identification value in each group of resources;

[0301] The resource with the largest identification value in each group of resources;

[0302] The first configured resource in each group of resources;

[0303] The resource with the smallest time slot offset value in each group of resources;

[0304] The resource with the largest time slot offset value in each group of resources.

[0305] In some embodiments, 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 the second preset time slot value; or,

[0306] 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 a third preset time slot value; or,

[0307] The time interval between the last resources in two consecutive groups of resources is greater than or equal to a fourth preset time slot value.

[0308] When a group contains multiple resources, the multiple resources can be combined to form resources of more antenna ports, which are used to determine the port index in the PMI. For example, the dimension of the precoding matrix is ​​v*128, where v represents the number of transmission layers and 128 represents the number of transmitting antenna ports. There is a one-to-one correspondence between the number of antenna ports corresponding to the PMI and the ports of each group of multiple measurement resources. For example, the first resource in each group corresponds to antenna ports 0-31, which is used to determine the channel information and precoding weights of ports 0-31; the second resource corresponds to antenna ports 32-63, which is used to determine the channel information and precoding weights of ports 32-63; the third resource corresponds to antenna ports 64-95, which is used to determine the channel information and precoding weights of ports 64-95; the fourth resource corresponds to antenna ports 96-127, which is used to determine the channel information and precoding weights of ports 96-127. For another example, the mapping relationship between the CSI-RS resource index or port index and the CSI or PMI calculation is determined according to the following method:

[0309] Mapping method 1: The sequential sorting / index within (1st resource, 1st polarization), then (2nd resource, 1st polarization), ..., then (Kth resource, 1st polarization), then (1st resource, 2nd polarization), then (2nd resource, 2nd polarization), ..., then (Kth resource, 2nd polarization) is mapped to the PMI.

[0310] Mapping method 2: (where K*n2=N2) Sequential sorting / indexing within:

[0311] For the 1st polarization, (the 1st n2-port in the 1st resource, the 1st polarization), (the 1st n2-port in the 2nd resource, the 1st polarization), … , (the 1st n2-port in the Kth resource, the 1st polarization), then (the 2nd n2-port in the 1st resource, the 1st polarization), … , (the 2nd n2-port in the Kth resource, the 1st polarization), … , then (the N1th n2-port in the 1st resource, the 1st polarization), … , (the N1th n2-port in the 2nd resource, the 1st polarization), … , (the N1th n2-port in the Kth resource, the 1st polarization), … , (the N1th n2-port in the Kth resource, the 1st polarization);

[0312] Then, for the second polarization, (the 1st n2 port in the 1st resource, the 2nd polarization), (the 1st n2 port in the 2nd resource, the 2nd polarization),…, (the 1st n2 port in the Kth resource, the 2nd polarization), then (the 2nd n2 port in the 1st resource, the 2nd polarization),…, (the 2nd n2 port in the Kth resource, the 2nd polarization),…, then (the N1th n2 port in the 1st resource, the 2nd polarization),…, (the N1th n2 port in the 2nd resource, the 2nd polarization),…, (the N1th n2 port in the Kth resource, the 1st polarization),…, (the N1th n2 port in the Kth resource, the 1st polarization) is mapped to the PMI.

[0313] N1 and N2 are high-layer signaling configurations, representing the number of antenna ports in the horizontal and vertical directions, respectively, and n2 = N2 / K.

[0314] Therefore, in order to determine the PMI, it is necessary to determine which of the multiple resources in a group is the first resource, which is the second resource, the third resource, and the fourth resource, and then determine which resource is used to determine the channel information and precoding matrix weight of which port. In some embodiments, the nth resource in each group of resources is one or more of the following:

[0315] The resource identification values ​​in each group of resources are arranged in ascending order, with the resource ranked nth;

[0316] The resource identifier values ​​in each resource group are arranged in descending order, with the resource ranked nth;

[0317] The nth resource in each resource group is arranged in the order of resource allocation;

[0318] In each group of resources, the resources are arranged in ascending order according to the time slot offset value, and the resource ranked nth;

[0319] In each group of resources, the resources are arranged in descending order according to the time slot offset value, and the resource ranked at the nth position.

[0320] The measurement reporting method of the embodiment of the present disclosure receives one or more first resource sets sent by a network side device, where the first resource set is a tracking reference signal TRS resource set or a channel state information CSI resource set; then, when multiple first resource sets are received from the network side device, the resources in the multiple first resource sets are measured to obtain measurement quantities; wherein, among the multiple first resource sets, some resources have the same QCL parameters, the same associated index values, the same corresponding resource subgroups, or different corresponding time resources; some resources have different QCL parameters, different associated index values, different corresponding resource subgroups, or the same corresponding time resources; thereby determining the corresponding relationship between the first resource set and the TRP, or the corresponding relationship with different time instants; so as to realize multi-T measurement reporting between RPs, and measurement reporting at different times of the same TRP; finally, reporting the measurement quantity to the network side device; the measurement quantity includes at least one of the following: frequency difference; delay difference; phase difference; TDCP amplitude; or, in the case of receiving one first resource set sent by the network side device, measuring at least one group of resources in the first resource set to obtain a measurement quantity; thereby determining the correspondence between each group of resources in the first resource set and the antenna port; in order to realize measurement reporting of more ports; finally, reporting the measurement quantity to the network side device, the measurement quantity includes the precoding matrix indication PMI; in this way, since the measurement quantity reported by the terminal includes the measurement quantity measured between multiple TRPs, the network side device is assisted to reduce or eliminate the influence of time-frequency synchronization error or reciprocity error based on the reported measurement quantity.

[0321] As shown in Figure 14, it is a flow chart of the measurement reporting method provided by the embodiment of the present disclosure. The method is applied to the network side device, that is, it is executed by the network side device. Specifically, the method includes:

[0322] Step 1401: Send one or more first resource sets for measurement to the terminal, where the first resource set is a tracking reference signal (TRS) resource set or a channel state information (CSI) resource set. When multiple first resource sets are sent to the terminal, some of the resources in the multiple first resource sets have the same QCL parameters, the same associated index values, the same corresponding resource subgroups, or different corresponding time resources; some of the resources have different QCL parameters, different associated index values, different corresponding resource subgroups, or the same corresponding time resources. Alternatively, when only one first resource set is sent to the terminal, at least one set of resources in the first resource set is used for measurement.

[0323] The multiple first resource sets are configured by the network side device. Among them, the TRS resource set includes multiple TRS resources; the CSI resource set includes multiple CSI-RS resources. Time resources can be time slots, symbols, etc.

[0324] It should be understood that among the multiple first resource sets, a part of the resources have the same QCL parameters, the same associated index values, the same corresponding resource subgroups or different corresponding time resources. The part of the resources here refers to a part of the first resource sets and all the resources within these first resource sets; and / or, refers to a part of the resources within a certain first resource set.

[0325] Among the multiple 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. The part of the resources here refers to a part of the first resource sets, and the associated index values ​​between these first resource sets are different, the corresponding resource subgroups are different, the corresponding time resources are the same, or the corresponding QCL parameters between these first resource sets are different; and / or, refers to a part of the resources within a certain first resource set.

[0326] Among the multiple first resource sets, some resources have the same QCL parameters, the same associated index values, the same corresponding resource subgroups, or different corresponding time resources; some resources have different QCL parameters, different associated index values, different corresponding resource subgroups, or the same corresponding time resources; the purpose is to enable the terminal to determine the corresponding relationship with the TRP, or determine the corresponding relationship with different moments, so as to realize measurement reporting between multiple TRPs and measurement reporting of the same TRP at different moments. For example, among the multiple first resource sets, some first resource sets correspond to the same TRP (such as determined based on the QCL parameters, several first resource sets with the same QCL parameters correspond to the same TRP; such as determined based on the index values, first resource sets with the same associated index values ​​correspond to the same TRP), and some first resource sets correspond to different TRPs (such as determined based on the QCL parameters, several first resource sets with different QCL parameters correspond to different TRPs respectively; such as determined based on the index values, first resource sets with different index values ​​correspond to different TRPs respectively). For another example, some first resource sets corresponding to the same time resources correspond to different TRPs, and some first resource sets corresponding to different time resources correspond to the same TRP; of course, the terminal can determine the correspondence with the TRP, or determine the correspondence with different time moments based on a combination of one or more of the above conditions.

[0327] Step 1402: Receive a measurement quantity reported by the terminal, where the measurement quantity includes at least one of the following: frequency difference; delay difference; phase difference; TDCP amplitude; and precoding matrix indicator (PMI).

[0328] It should be noted that the frequency difference can be the frequency difference between different TRPs, or the frequency difference at different times of the same TRP; the delay difference can be the delay difference between different TRPs, or the delay difference at different times of the same TRP; the phase difference can be the phase difference between different TRPs, or the phase difference at different times of the same TRP.

[0329] The frequency difference can be represented by a first amplitude, that is, the frequency difference is a specific value or amplitude, and the value or amplitude is used to characterize the frequency difference.

[0330] The network-side device receives the measurement data reported by the terminal and can eliminate the effects of time-frequency synchronization errors or reciprocity errors based on the reported measurement data. For example, if the reported measurement data is the frequency difference or phase difference between different TRPs, the frequency synchronization error can be eliminated; if the reported measurement data is the delay difference between different TRPs, the time synchronization error can be eliminated.

[0331] In some embodiments, the method of the present disclosure further comprises:

[0338] It should be noted that K represents the number of TRPs, and N represents the number of first resource sets at different times of a TRP.

[0339] For easier understanding of the above embodiments, please refer to the detailed description of Example 1 and Example 2 on the terminal side, which will not be repeated here.

[0340] Alternatively, K first resource sets are configured for the terminal.

[0341] In some embodiments, when K first resource sets are configured for the terminal,

[0342] All resources in the same first resource set have the same QCL parameters, and resources in different first resource sets have different QCL parameters; or,

[0343] Some resources in each of the first resource sets have different QCL parameters; or,

[0344] The same first resource set is associated with the same index value, and different first resource sets are associated with different index values; or,

[0345] The same first resource set corresponds to the same resource subgroup, or the same resource subgroup corresponds to the same time resource.

[0346] To facilitate understanding of the above embodiments, please refer to the descriptions of Examples 3 to 6 on the terminal side, which will not be repeated here.

[0347] After receiving the measurement value reported by the terminal, the network side device performs processing to reduce or eliminate the time-frequency synchronization error based on the reported measurement value.

[0348] When frequency synchronization errors exist between multiple TRPs, receiving at the receive frequency of one TRP can cause the channels of other TRPs to exhibit temporal selectivity, meaning they vary rapidly over time. The UE can measure and report at least one of the following: frequency difference, phase difference, or TDCP value by measuring the TRS or CSI-RS. After receiving the UE's report, the network device can reduce or eliminate the error in the following three ways:

[0349] Method 1: Perform transmission pre-compensation / pre-processing based on UE reports to eliminate frequency desynchronization errors and make the channel flat in time.

[0350] Method 2: Adjust the granularity of the precoding matrix based on the UE's report, such as reducing the feedback period / interval, so that the CSI reporting granularity matches the current time-varying channel characteristics;

[0351] Method three: Determine the service TRP based on the UE's report (i.e., select TRP), such as selecting a TRP with a relatively small frequency error for CJT transmission.

[0352] When there is a time synchronization error between multiple TRPs, if reception is performed according to the receive timing of one TRP, the channels of other TRPs will exhibit frequency selectivity, that is, they will change rapidly in time. The UE can measure at least one of the delay difference or phase difference by measuring the TRS or CSI-RS and report it. After receiving the report from the UE, the network side equipment can reduce the error in the following three ways:

[0353] Method 1: Perform transmission pre-compensation / pre-processing based on UE reports to eliminate time synchronization errors and make the channel flat in frequency.

[0354] Method 2: Adjust the granularity of the precoding matrix according to the UE report, such as reducing the sub-band granularity, so that the CSI reporting granularity matches the current frequency channel characteristics.

[0355] Method three: Determine the service TRP based on the UE's report (i.e., select TRP), such as selecting a TRP with a relatively small time error for CJT transmission.
