Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of wireless communication, and particularly relates to a P-MPR reporting method and device, a terminal and a network side device. BACKGROUND

[0002] In order to ensure human health, some organizations or countries stipulate the standard of maximum permissible exposure (MPE). When the radio transmission power is large and the radio frequency device is close to the human body, in order to ensure that the MPE standard is met, the transmission power needs to be reduced. In the related art, a terminal determines the maximum output power according to a power management maximum power reduction (P-MPR) and reports it to the network, so as to ensure that the available battery energy absorption requirement is met and the unexpected radiation requirement is solved.

[0003] In the related art, the terminal reports the P-MPR value in a power headroom report (PHR) medium access control (MAC) control element (CE). In the related art, the P-MPR reporting is based on a component carrier (CC), that is, one P-MPR value is reported for each CC. However, in a high frequency band, the terminal needs to use a beam for uplink transmission. When the terminal has multiple antenna panels, each panel will generate at least one beam. Since the spatial propagation paths of the beams are different, the P-MPR values of the antenna panels or the beams are likely to be different. Therefore, the terminal may measure multiple P-MPRs. In this case, how to trigger the P-MPR reporting and what to report have not been effectively solved. SUMMARY

[0033] The reporting scheme of the P-MPR provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings, through some embodiments and application scenarios.

[0034] Figure 2 A flowchart of a method for reporting the P-MPR in the embodiments of the present application is shown, and the method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As shown in the figure, the method can include the following steps. Figure 2

[0035] S210, the terminal determines that the reporting condition is met, wherein the reporting condition includes at least one of the following: the correspondence between the P-MPR and the reference signal resource identification changes, at least one of the measured multiple P-MPRs meets the preset condition.

[0036] ​In the embodiments of the present application, the terminal can determine the correspondence between the P-MPR and the reference signal resource identifier. For example, the terminal can measure one P-MPR based on each antenna panel, i.e., the P-MPR is per Panel, and the terminal can set the correspondence between each P-MPR and the reference signal resource identifier of the beam information on the corresponding antenna panel. For another example, the terminal can measure one P-MPR based on each beam, i.e., the P-MPR is per beam, and the terminal can set the correspondence between each P-MPR and the reference signal resource identifier of the corresponding beam.

[0037] In the embodiments of the present application, the reference signal resource identifier includes but is not limited to at least one of the following:

[0038] Synchronization signal / physical broadcast channel signal block (or synchronization signal block) (Synchronization Signal and PBCH Block, SSB) resource (Resource) indicator (Indicator), i.e., SSBRI;

[0039] Channel state information reference signal (Channel State Information Reference Signal, CSI-RS) resource (Resource) indicator (Indicator), i.e., CRI.

[0040] S212, the terminal sends a first report, wherein the first report is used to indicate the changed correspondence, and / or the first report includes the at least one P-MPR.

[0041] Through the above technical solutions provided by the embodiments of the present application, when the correspondence between the P-MPR and the reference signal resource identifier changes and / or at least one P-MPR in the multiple P-MPRs measured by the terminal meets the preset condition, the terminal sends a first report, the first report indicates the changed correspondence and / or the first report includes the at least one P-MPR, thereby solving the problem of how to trigger P-MPR reporting and what content to report in the scenario of measuring multiple P-MPRs by the terminal.

[0042] In one possible implementation, the change of the correspondence between the P-MPR and the reference signal resource identifier can include at least one of the following:

[0043] (1) The correspondence between the P-MPR and the first reference signal resource identifier is not reported.

[0044] For example, the second report reported at time T1 includes {P-MPR1, CRI1, CRI2} {P-MPR2, CRI3, CRI4}, at time T2, the terminal determines that CRI5 needs to be reported, the P-MPR corresponding to CRI5 is P-MPR1, and the corresponding relationship between P-MPR1 and CRI5 is not reported in the second report, so it is determined that the reporting condition is met.

[0045] Alternatively, the first reference signal resource identifier can be determined according to beam measurement or beam report. For example, in the above example, the terminal reports a beam report at time T2, which includes {CRI1, CRI5, CRI3, CRI4} {L1-RSRP1, L1-RSRP5, L1-RSRP3, L1-RSRP4}, and CRI5 is not included in the second report reported before, so the terminal determines to trigger the reporting of the first report, indicating the corresponding relationship between P-MPR1 and CRI5, so that the network side device obtains the latest P-MPR and SSBRI / CRI corresponding relationship, so as to select the beam represented by SSBRI / CRI with smaller P-MPR value and corresponding larger L1-RSRP when scheduling channel transmission.

[0046] (2) The corresponding relationship between P-MPR and the second reference signal resource identifier is deleted.

[0047] For example, the second report reported at time T1 includes {P-MPR1, CRI1, CRI2} {P-MPR2, CRI3, CRI4}, at time T2, the terminal determines that CRI1 does not need to be reported, and the corresponding relationship between CRI1 and P-MPR1 is deleted, so it is determined that the reporting condition is met.

[0048] Alternatively, the second reference signal resource identifier can be determined according to beam measurement or beam report. For example, in the above example, when the terminal performs beam measurement at time T2, it is found that the value of L1-RSRP1 corresponding to CRI1 is less than a predetermined value, i.e. the beam link signal quality corresponding to CRI1 is poor, then the terminal determines that CRI1 does not need to be reported, deletes the corresponding relationship between P-MPR1 and CRI1, triggers the reporting of the first report, and the first report can include {P-MPR1, CRI2} {P-MPR2, CRI3, CRI4}, so that the network side device obtains the latest P-MPR and SSBRI / CRI corresponding relationship, so as to select the beam represented by SSBRI / CRI with smaller P-MPR value and corresponding larger L1-RSRP when scheduling channel transmission.

[0049] For example, the terminal determines that P-MPR1 corresponds to CRI1 and CRI2, and P-MPR2 corresponds to CRI3 and CRI4, and includes {P-MPR1, CRI1, CRI2} {P-MPR2, CRI3, CRI4} in the second report reported at time T1. The terminal includes {CRI3, CRI4, CRI5, CRI6} {L1-RSRP3, L1-RSRP4, L1-RSRP5, L1-RSRP6} in the beam report reported at time T2, and determines that P-MPR1 corresponds to CRI3 and CRI4, and P-MPR2 corresponds to CRI5 and CRI6. CRI3 and CRI4 correspond to P-MPR1 in the second report, and after the subsequent beam measurement, the terminal learns that the beam information corresponding to P-MPR1 is CRI3 and CRI4, that is, the corresponding relationship between P-MPR2 and CRI3 and CRI4 needs to be deleted, and the corresponding relationship between P-MPR1 and CRI3 and CRI4 needs to be added, and then the terminal triggers the report and sends the first report. The first report can include {P-MPR1, CRI3, CRI4} {P-MPR2, CRI5, CRI6}, so that the network side device can obtain the latest corresponding relationship between P-MPR and SSBRI / CRI. Otherwise, if P-MPR2 is very poor and CRI3 is very good, the network side device does not know whether CRI3 should be used to update the beam, and actually CRI3 corresponds to a better P-MPR1.

[0050] In one possible implementation, at least one P-MPR of the multiple P-MPRs satisfies a preset condition, including:

[0051] (1) The measurement value of the at least one P-MPR of the multiple P-MPRs is greater than or equal to a first threshold.

[0052] For example, the measurement value of at least one P-MPR of the multiple measured P-MPRs of the terminal is greater than or equal to a first threshold. That is, the measurement value of at least one P-MPR of the multiple measured P-MPRs is relatively large, and the network needs to be notified in time, and then the report is triggered. When all the multiple measured P-MPRs are greater than or equal to the first threshold, the report is triggered.

[0053] For example, the measurement value of at least one P-MPR of the multiple P-MPRs corresponding to the reference signal resource identifier is greater than or equal to a first threshold. That is, the measurement value of one or more P-MPRs of the multiple P-MPRs corresponding to the reference signal resource identifier is greater than or equal to a first threshold, and the network needs to be notified in time, and then the report is triggered.

[0054] The reference signal resource identifier can be configured by the network side device, for example, the identifier of the multiple reference signal resources configured by the network side device for measuring the beam or for the beam report.

[0055] Alternatively, the reference signal resource identifier can also be determined by the terminal according to beam measurement or beam reporting. For example, when the P-MPR value corresponding to the CRI in the last reported beam report is poor, the terminal triggers the reporting of the P-MPR value, so that the network side device can obtain the P-MPR value, and avoid the network side device selecting the corresponding beam because the signal quality of the CRI corresponding to the P-MPR is good.

[0056] (2) The change amount of the measurement value of the at least one P-MPR in the plurality of P-MPRs is greater than or equal to a second threshold.

[0057] For example, when the change amount of the measurement value of the at least one P-MPR in the plurality of measured P-MPRs of the terminal relative to the last reporting (for example, the second reporting) is greater than or equal to a second threshold, the terminal triggers the reporting. That is, the change amount of the measurement value of the at least one P-MPR in the plurality of measured P-MPRs is relatively large, and the network side device needs to be notified, so the terminal triggers the reporting. Among them, when the change amount of the measurement value of all P-MPRs relative to the last reporting is greater than or equal to a second threshold, the terminal triggers the reporting.

[0058] For another example, the change amount of the measurement value of the at least one P-MPR in the plurality of P-MPRs corresponding to the reference signal resource identifier is greater than or equal to a second threshold. That is, when the change amount of the measurement value of one or more P-MPRs in the plurality of P-MPRs corresponding to the reference signal resource identifier is greater than or equal to a second threshold, the terminal triggers the reporting.

[0059] Among them, the reference signal resource identifier can be configured by the network side device, for example, the identifier of the plurality of reference signal resources configured by the network side device for measuring beams or for beam reporting.

[0060] Alternatively, the reference signal resource identifier can also be determined by the terminal according to beam measurement or beam reporting. For example, the reference signal resource identifier is the CRI in the last reported beam report.

[0061] (3) The number of P-MPRs with measurement values greater than or equal to a third threshold in the plurality of P-MPRs is greater than a first number.

[0062] For example, when the number of P-MPRs with measurement values greater than a third threshold in the plurality of measured P-MPRs of the terminal is greater than a first number, the terminal triggers the reporting. That is, the number of P-MPRs with poor P-MPR values in the plurality of measured P-MPRs is relatively large, and the network side device needs to be notified, so the terminal triggers the reporting.

[0063] For example, if the number of P-MPRs whose measurement values are greater than the third threshold value in the plurality of P-MPRs corresponding to the reference signal resource identifier is greater than the first number, the reporting is triggered. That is, if the number of P-MPRs whose P-MPR values are poor is large in the plurality of P-MPRs corresponding to the reference signal resource identifier, the network side device needs to be notified, and the reporting is triggered.

[0064] The reference signal resource identifier can be configured by the network side device, for example, an identifier of a plurality of reference signal resources configured by the network side device for measuring a beam or for a beam report.

[0065] Alternatively, the plurality of reference signal resource identifiers can also be determined by the terminal according to beam measurement or beam reporting. For example, the reference signal resource identifier is CRI in the beam report reported last time or multiple times.

[0066] (4) The number of P-MPRs whose change amount of measurement values is greater than or equal to the fourth threshold value in the plurality of P-MPRs is greater than the second number;

[0067] For example, if the number of P-MPRs whose change amount of measurement values relative to the last reported is greater than the fourth threshold value in the plurality of measurement P-MPRs of the terminal is greater than the second number, the reporting is triggered. That is, if the number of P-MPRs whose P-MPR value changes greatly is large in the plurality of measurement P-MPRs, the network side device needs to be notified, and the reporting is triggered.

[0068] For example, if the number of P-MPRs whose change amount of measurement values relative to the last reported is greater than the fourth threshold value in the plurality of P-MPRs corresponding to the reference signal resource identifier is greater than the second number, the reporting is triggered. That is, if the number of P-MPRs whose P-MPR value changes greatly is large in the plurality of P-MPRs corresponding to the reference signal resource identifier, the network side device needs to be notified, and the reporting is triggered.

[0069] The reference signal resource identifier can be configured by the network side device, for example, an identifier of a plurality of reference signal resources configured by the network side device for measuring a beam or for a beam report.

[0070] Alternatively, the plurality of reference signal resource identifiers can also be determined by the terminal according to beam measurement or beam reporting. For example, the reference signal resource identifier is CRI in the beam report reported last time or multiple times.

[0071] (5) The first timer corresponding to the at least one P-MPR in the plurality of P-MPRs expires.

[0072] In the possible implementation, each P-MPR can be reported periodically, each of the plurality of P-MPRs corresponds to a first timer respectively, when the first timer corresponding to a certain P-MPR expires, the P-MPR corresponding to the first timer is triggered to be reported. Alternatively, the plurality of P-MPRs correspond to a first timer collectively, when the first timer expires, the plurality of P-MPRs corresponding to the first timer are triggered to be reported.

[0073] In each of the above implementations, a preset time window can be optionally set, that is, within the preset time window, when the at least one P-MPR meets the preset condition, the reporting is triggered.

[0074] In a possible implementation, the terminal sending the first report can include: in the case that the second timer does not run or expires, and the P-MPR corresponding to the second timer meets the reporting condition, the terminal sends the first report, wherein the second timer corresponds to one or more P-MPRs. That is, in the possible implementation, whether the reporting condition is met can be determined in the case that the second timer does not run or expires, and the first report is reported in the case that it is determined that the reporting condition is met.

[0075] For example, the network side device can configure a second timer for a plurality of P-MPRs (which can be all P-MPRs), in this case, if the second timer expires or does not run, and the plurality of P-MPRs corresponding to the second timer that expires or does not run meet the reporting condition, the reporting of the first report is triggered, for example, if the second timer expires or does not run, and there is a change in the correspondence between the P-MPR and the reference signal resource identifier in the plurality of P-MPRs corresponding to the second timer, the reporting is triggered. For another example, if the second timer expires or does not run, and at least one P-MPR of the plurality of P-MPRs corresponding to the second timer meets the preset condition, the reporting is triggered.

[0076] For example, at least one P-MPR of the plurality of P-MPRs corresponding to the second timer meets one of the following conditions, the reporting is triggered:

[0077] The measurement value of at least one P-MPR of the plurality of P-MPRs corresponding to the second timer that expires or does not run is greater than or equal to a first threshold value;

[0078] The change amount of the measurement value of at least one P-MPR of the plurality of P-MPRs corresponding to the second timer that expires or does not run is greater than or equal to a second threshold value;

[0079] The number of P-MPRs of the plurality of P-MPRs corresponding to the second timer that expires or does not run, whose measurement value is greater than or equal to a third threshold value, is greater than a first number;

[0080] The number of P-MPRs corresponding to the second timer that expires or does not run and whose change in measured value is greater than or equal to the fourth threshold is greater than the second number.

[0081] Alternatively, the network-side device can configure one second timer for each P-MPR in the plurality of P-MPRs, and in this case, if the second timer expires or does not run and the P-MPR corresponding to the second timer that expires or does not run meets the reporting condition, the first report is triggered to be reported. For example, if the second timer expires or does not run and the corresponding P-MPR and the reference signal resource identifier have a changed correspondence relationship, the report is triggered. For another example, if the second timer expires or does not run and the corresponding P-MPR meets a preset condition, the report is triggered.

[0082] For example, if the P-MPR corresponding to the second timer meets one of the following conditions, the report is triggered:

[0083] The measured value of the P-MPR corresponding to the second timer is greater than or equal to the first threshold;

[0084] The change in the measured value of the P-MPR corresponding to the second timer is greater than or equal to the second threshold.

[0085] In the above possible implementation manners, the second timer can be reused as the MPE prohibition timer (mpe-ProhibitTimer), or it can also be a timer specially defined for P-MPR reporting.

[0086] In one possible implementation manner, the first report can include N P-MPRs, that is, the first report can report N P-MPRs. Wherein, N can be determined based on at least one of the following:

[0087] (1) The capability of the terminal, for example, the terminal supports the number or maximum number of reported P-MPRs;

[0088] (2) The configuration of the network-side device, for example, the network-side device can configure the maximum allowed number of reported P-MPRs, or can directly configure the number of reported P-MPRs;

[0089] (3) The protocol agreement, for example, the protocol can agree on the maximum allowed number of reported P-MPRs, or can directly agree on the number of reported P-MPRs.

[0090] In specific applications, N can be a fixed value, or N can also be any value not greater than the maximum allowed number of P-MPRs.

[0091] In a possible implementation, the first report can further include M reference signal resource identifiers corresponding to each of the N P-MPRs, where M is an integer greater than or equal to 1. That is, for each reported P-MPR, the first report can further report M reference signal resource identifiers corresponding to the P-MPR. For example, for each reported P-MPR value, M SSBRI and / or CRI corresponding to the P-MPR value are reported. The M can be determined based on at least one of the following:

[0092] (1) the capability of the terminal, for example, the number or maximum number of SSBRI and / or CRI corresponding to each reported P-MPR supported by the terminal;

[0093] (2) the configuration of the network-side device, for example, the network-side device can configure the maximum allowed number of reference signal resource identifiers corresponding to one reported P-MPR, that is, the maximum number of reference signal resource identifiers corresponding to one reported P-MPR, or can directly configure the specific number of reference signal resource identifiers corresponding to one reported P-MPR;

[0094] (3) a protocol agreement, for example, the protocol can agree on the maximum allowed number of reference signal resource identifiers corresponding to one reported P-MPR, or can directly agree on the specific number of reference signal resource identifiers corresponding to one reported P-MPR.

[0095] In a specific application, M can be a fixed value, or M can be no more than the maximum allowed number of reference signal resource identifiers corresponding to one P-MPR.

[0096] Optionally, the number of reference signal resource identifiers corresponding to each of the N P-MPRs is the same, for example, the network-side device configures the specific number M of reference signal resource identifiers corresponding to one reported P-MPR, and for each reported P-MPR, the number of reference signal resource identifiers corresponding to each reported P-MPR in the first report is the same, that is, M.

[0097] Alternatively, the number of reference signal resource identifiers corresponding to each of the N P-MPRs is not the same. For example, the network-side device configures the maximum allowed number of reference signal resource identifiers corresponding to one reported P-MPR, and for each reported P-MPR, the number of reference signal resource identifiers corresponding to each reported P-MPR in the first report can be different, as long as it is not more than the maximum allowed number.

[0098] In a possible implementation, a maximum value of a total number of reference signal resource identities corresponding to the N P-MPRs in the first report is K, where K is a predetermined value. For example, K can be configured by the network side device or agreed by a protocol, and the embodiment of the present application is not limited in this regard.

[0099] In a possible implementation, the first report further indicates at least one of the following: the first report includes reference signal resource identities corresponding to each of the P-MPRs, the number N, and the number of reference signal resource identities corresponding to each of the N P-MPRs. That is, the first report can further indicate, in an explicit or implicit manner, whether the first report includes reference signal resource identities corresponding to P-MPRs, the number of reported P-MPRs, and the number of reference signal resource identities corresponding to each P-MPR.

[0100] In the above possible implementation, the reference signal resources in the candidate reference signal resource pool are one of the following:

[0101] (1) configured by the network side device; that is, the candidate reference signal resource pool is configured by the network side device.

[0102] (2) determined according to beam measurement or beam reporting, where the identity of the reference signal resource in the candidate reference signal resource pool is the same as the identity of the reference signal resource included in the beam reporting, that is, the reference signal resource corresponding to the identity of the reference signal resource included in the beam reporting is the candidate reference signal resource; or the identity of the reference signal resource in the candidate reference signal resource pool is included in the beam reporting, that is, the identity of the reference signal resource in the candidate reference signal resource pool is part of the identity of the reference signal resource included in the beam reporting; or the identity of the reference signal resource in the candidate reference signal resource pool includes the identity of the reference signal resource in the beam reporting, that is, the identity of the reference signal resource included in the beam reporting is the identity of part of the reference signal resource in the candidate reference signal resource pool.

[0103] In a possible implementation, the reference signal resource identity indicated by the first report can be the identity of one or more reference signal resources in the candidate reference signal resource pool. That is, the terminal can select a reference signal resource from the candidate reference signal resource pool and report the identity of the selected reference signal resource.

[0104] Optionally, the reference signal resource identity indicated by the first report is the identity of a reference signal resource selected from the candidate reference signal resource pool according to beam measurement or beam reporting. Optionally, the signal quality corresponding to the reference signal resource identity indicated by the first report is greater than or equal to a first preset value.

[0105] For example, the terminal can select a reference signal resource with better signal quality from the candidate reference signal resource pool, and report an identifier of the reference signal resource with better signal quality. For example, the UE can select the SSBRI / CRI reported in the first report based on one or more latest beam reports, for example, the selected SSBRI / CRI corresponds to a L1-RSRP / L1-SINR value in the beam report greater than or equal to a first preset value.

[0106] In one possible implementation, in order to save the overhead of the first report, the P-MPR reported in the first report is a P-MPR that satisfies the preset condition. For example, the P-MPR reported in the first report is a P-MPR whose change in measurement value exceeds a second threshold, or the measurement value of the P-MPR reported in the first report exceeds a first threshold, etc.

[0107] In the case where the P-MPR reported in the first report is a P-MPR that satisfies the preset condition, in order for the network side device to know which P-MPRs are not reported, the first report can optionally further indicate the P-MPRs not reported in the first report.

[0108] Of course, it is not limited thereto, and the P-MPR reported in the first report can also include a P-MPR that does not satisfy the preset condition.

[0109] In one possible implementation, in order to save the overhead of the first report, the reference signal resource identifier reported in the first report is different from the reference signal resource identifier reported in the second report, wherein the second report is reported before the first report. That is, only the reference signal resource identifier that has changed relative to the second report is reported in the first report. For example, SSBRI / CRI that is different from the previous time is reported, such as newly added SSBRI / CRI and deleted SSBRI / CRI, etc.

[0110] Optionally, in the case where the reference signal resource identifier reported in the first report is different from the reference signal resource identifier reported in the second report, in order for the network side device to obtain whether the reference signal resource identifier reported in the first report is newly added or deleted, the first report further indicates at least one of the following:

[0111] The reference signal resource identifier newly added in the first report relative to the second report;

[0112] The reference signal resource identifier deleted in the first report relative to the second report.

[0113] Of course, it is not limited thereto, and the reference signal resource identifier reported in the first report can also include a reference signal resource identifier that has not changed. That is, the first report and the second report can indicate the same reference signal resource identifier.

[0114] In one possible implementation, the P-MPR reported in the first report includes a first target P-MPR, wherein the reference signal resource identifier corresponding to the first target P-MPR corresponds to a second target P-MPR in the second report, the first target P-MPR is different from the second target P-MPR, and the second report is reported before the first report. That is, if a certain reference signal resource corresponds to a second target P-MPR in the second report, and is changed to correspond to a first target P-MPR when the first report is reported, the first target P-MPR is reported in the first report, and optionally, the reference signal resource identifier corresponding to the first target P-MPR can also be reported.

[0115] In one possible implementation, in order to save the overhead of the first report, when reporting the P-MPR, the first report can be reported by one of the following:

[0116] (1) Report the difference between each P-MPR; that is, include the difference between each P-MPR in the first report, rather than the actual value of each P-MPR;

[0117] (2) Report the difference of each P-MPR relative to the last reported value. For example, the first report includes the difference of each P-MPR relative to the value of that P-MPR in the second report of the last reported value.

[0118] In one possible implementation, the first report also includes the index or identification number (ID) corresponding to each P-MPR reported. Different indexes or IDs can correspond to different panels or beams, etc.

[0119] In one possible implementation, the first report also includes the downlink channel quality (for example, DL RSRP) or virtual power headroom (virtual PHR) corresponding to each P-MPR reported.

[0120] Through the technical solutions provided by the embodiments of the present application, the triggering condition for the terminal to report the P-MPR is given, and the information content of the UE to report the P-MPR to the network, so that the network can quickly and accurately know the link quality of the panel and / or beam of the terminal.

[0121] Figure 3Fig. 1 shows a flowchart of a method for indicating a beam according to an embodiment of the present application. The method 300 can be performed by a network side device. In other words, the method can be performed by software or hardware installed on the network side device. As shown in Fig. 1, the method can include the following steps. Figure 3

For example, the network side device determines the QCL-TypeD RS of each CSI-RS resource in the CSI-RS resource set according to the SSBRI / CRI in the first report, and uses the MAC CE to instruct the terminal.

[0127] (2) indicating to perform beam measurement on the target information corresponding to the beam, wherein the target information has an association relationship with the P-MPR in the first report, and the target information includes one of the following: antenna panel information, beam information, index, ID. For example, trigger to perform measurement on the RS resource set corresponding to a certain panel, index or ID.

[0128] Optionally, the network side device can also indicate a new common beam based on the first report, or update the TCI state or spatial relation of a certain channel or RS.

[0138] In a possible implementation, at least one P-MPR of the measured multiple P-MPRs satisfies a preset condition, including that the at least one P-MPR satisfies the preset condition within a preset time window.

[0142] In a possible implementation, before receiving the first report, the method further includes: sending, by the network-side device, configuration information to the terminal, wherein the configuration information is used to indicate at least one of the following:

[0159] Figure 4 Another flowchart of a P-MPR reporting method in the embodiments of the present application is shown, which can be executed by a terminal and a network side device. In other words, the method can be executed by software or hardware installed on the terminal and the network side device. As shown in the figure, the method can include the following steps. Figure 4

[0160] S410, when at least one trigger condition is met, the UE sends a P-MPR report, i.e., the first report described above, to the network side device.

[0161] The trigger condition can include the following conditions 1-5.

[0162] Condition 1: At least one SSBRI / CRI in the (last or multiple) beam report is not in the (last or multiple) P-MPR report.

[0163] For example, the P-MPR report at time T1 includes {P-MPR1, CRI1, CRI2} {P-MPR2, CRI3, CRI4}, the beam report at T2 includes {CRI1, CRI5, CRI3, CRI4} {L1-RSRP1, L1-RSRP5, L1-RSRP3, L1-RSRP4}, at this time, CRI5 is not in the previous P-MPR report, then the UE needs to trigger the P-MPR report, so that the network obtains the latest correspondence between P-MPR and SSBRI / CRI, so as to select the beam represented by SSBRI / CRI with smaller P-MPR value and corresponding larger L1-RSRP when scheduling channel transmission.

[0164] Condition 2: The correspondence between SSBRI / CRI in the (last or multiple) beam report and the P-MPR value in the (last or multiple) P-MPR report changes.

[0165] ​For example, UE determines P-MPR1 corresponds to CRI1 and CRI2, P-MPR2 corresponds to CRI3 and CRI4, UE includes {P-MPR1, CRI1, CRI2} {P-MPR2, CRI3, CRI4} in P-MPR report at T1.

[0166] UE includes {CRI3, CRI4, CRI5, CRI6} {L1-RSRP3, L1-RSRP4, L1-RSRP5, L1-RSRP6} in beam report at T2, UE determines P-MPR1 corresponds to CRI3 and CRI4, P-MPR2 corresponds to CRI5 and CRI6,

[0167] Therefore, CRI3 and CRI4 correspond to P-MPR2 in previous P-MPR report, after beam measurement, UE considers CRI5 and CRI6 correspond to P-MPR2, CRI3 and CRI4 correspond to P-MPR1, UE needs to trigger P-MPR report, so that network obtains the latest P-MPR and SSBRI / CRI correspondence. Otherwise, if P-MPR2 is very poor, CRI3 is very good, network will not know whether CRI3 should be used to update beam, and actually CRI3 corresponds to better P-MPR1.

[0168] Condition 3: P-MPR value (or absolute value) in P-MPR report corresponding to SSBRI / CRI in (the latest one or more times) beam report is greater than or equal to a first preset value, and / or, the number of P-MPRs whose P-MPR value (or absolute value) in P-MPR report corresponding to SSBRI / CRI in (the latest one or more times) beam report is greater than or equal to a second preset value is greater than or equal to a preset number

[0169] For example, assuming that each P-MPR value corresponds to one CRI, when the P-MPR value corresponding to CRI in beam report is very poor, and / or, the number of poor P-MPRs is relatively large, UE reports P-MPR report.

[0170] Condition 4: The reporting condition of one measured P-MPR is extended, for example, it can include:

[0171] i. The P-MPR value of at least one measured P-MPR is greater than a first threshold, or the change amount of the P-MPR value of at least one measured P-MPR is greater than a second threshold;

[0172] ii. All measured P-MPRs have P-MPR values greater than a first threshold, or all measured P-MPRs have P-MPR values that change by an amount greater than a second threshold

[0173] iii. One measured P-MPR has a P-MPR value greater than a first threshold, or one measured P-MPR has a P-MPR value that changes by an amount greater than a second threshold.

[0174] iv. In (i)-(iii) above, add that within a predetermined time window, for example, at least one measured P-MPR has a P-MPR value greater than a first threshold within the predetermined time window.

[0175] Condition 5: The MPE timer of at least one of the multiple P-MPRs expires, wherein the MPE timer can be configured by the network side device.

[0176] It should be noted that the correspondence between the P-MPR value in the P-MPR report and the SSBRI / CRI can be determined by the UE.

[0177] For the above trigger conditions, the trigger condition can be defined as when at least one of the multiple P-MPRs corresponds to an MPE prohibit timer that expires, or all P-MPRs correspond to MPE prohibit timers that expire, when the above trigger condition is met, the UE sends a P-MPR report to the network. For example, in the case of multiple P-MPRs corresponding to the expired timer, the multiple P-MPRs satisfy any one of the above conditions 1 to 4, then the reporting is triggered. In the case of one P-MPR corresponding to the expired timer, the value of the P-MPR is greater than a first threshold, or the amount of change of the value of the P-MPR is greater than a second threshold, or the correspondence between the P-MPR and the SSBRI / CRI changes, then the reporting is triggered.

[0178] When reporting the P-MPR report, the UE can select SSBRI / CRI from the candidate SSBRI / CRI resource pool and report it in the P-MPR report. Specifically, there can be the following reporting methods

[0179] a) Report N P-MPR values

[0180] Wherein the value of N can be determined based on at least one of UE capability, network configuration, and protocol agreement.

[0181] The fixed number of P-MPRs determined based on at least one of UE capability, network configuration, and protocol agreement, or the maximum allowed number of P-MPRs.

[0182] b) For each P-MPR value, report its corresponding M SSBRI / CRI.

[0183] Wherein, the value of M can be determined based on at least one of UE capability, network configuration, protocol agreement.

[0184] Optionally, for each P-MPR value, the number of its corresponding SSBRI / CRI, M, can be different or all the same.

[0185] c) For each P-MPR value, report its corresponding maximum M SSBRI / CRI.

[0186] Wherein, the value of M is determined based on at least one of UE capability, network configuration, protocol agreement.

[0187] Optionally, for each P-MPR value, the maximum number of its corresponding SSBRI / CRI, M, can be different or all the same.

[0188] It can also be limited that for all P-MPR values, the total number of SSBRI / CRI is maximum K.

[0189] d) For the above a) and b), the number of P-MPR values and / or the number of SSBRI / CRI corresponding to each P-MPR value is indicated in the P-MPR report.

[0190] In the embodiments of the present application, the candidate SSBRI / CRI resource pool can be configured by the network.

[0191] Optionally, the candidate SSBRI / CRI resource pool and the SSRBI / CRI in the beam report can be the same, or one contains the other.

[0192] Optionally, when reporting, the SSBRI / CRI selected by the UE can be all the SSBRI / CRI in the pool. Further, these SSBRI / CRI correspond to multiple P-MPR values.

[0193] Optionally, the UE can select the SSBRI / CRI reported in the P-MPR report based on the latest one or more beam reports, for example, the L1-RSRP / L1-SINR value in the beam report corresponding to the selected SSBRI / CRI is greater than or equal to a preset value.

[0194] Optionally, in the P-MPR report, only the P-MPR values whose measured P-MPR changes reach or exceed a pre-set threshold are reported, i.e., the reporting of P-MPR is omitted when the P-MPR change is small. Thus, the reporting overhead can be reduced. Optionally, the P-MPR report can also explicitly or implicitly indicate which P-MPRs are not reported.

[0195] Optionally, in the P-MPR report, the index / ID corresponding to each P-MPR value is also included.

[0196] Optionally, in the P-MPR report, the DL RSRP, virtual PHR, etc. corresponding to each P-MPR or each SSBRI / CRI are also included.

[0197] Optionally, the following ways of saving P-MPR report overhead can also be used:

[0198] i. Report the difference between different P-MPR values

[0199] ii. Report the difference between each P-MPR and the previous value

[0200] iii. Report the SSBRI / CRI that is different from the previous one, such as, report the newly added SSBRI / CRI, the deleted SSBRI / CRI. Optionally, the P-MPR report can explicitly or implicitly indicate the newly added and / or deleted SSBRI / CRI.

[0201] S412, the network side device receives the P-MPR report and sends signaling to the UE.

[0202] The signaling can be used for at least one of the following:

[0203] a) Update the QCL-TypeD RS of the RS resource in the RS resource set;

[0204] i. For example, use MAC CE to update the QCL-TypeD RS of each CSI-RS resource in the CSI-RS resource set according to the SSBRI / CRI in the P-MPR report;

[0205] b) Indicate a new common beam;

[0206] c) Update the TCI state or spatial relation of a certain channel or RS;

[0207] d) Beam training indicating a specific panel / index / ID; for example, triggering RS resource set corresponding to a certain panel / index / ID.

[0208] It should be noted that the P-MPR reporting method provided in the embodiments of the present application can be executed by a P-MPR reporting device, or a control module in the P-MPR reporting device for executing the P-MPR reporting method. In the embodiments of the present application, the P-MPR reporting method is executed by the P-MPR reporting device as an example, and the P-MPR reporting device provided in the embodiments of the present application is described.
