[0020] Hereinafter, with reference to the drawings, the method for determining channel state information according to the embodiments of the present application will be described in detail by way of specific embodiments and their application scenarios.
[0021] FIG. 2 is a flowchart of a method for determining channel state information according to an embodiment of the present application. This method for determining channel state information is executed by a terminal and includes the following steps.
[0022] Step 201, Based on at least one of the mapping relationships between multiple sets of channel measurement resources (CMR) and multiple sets of interference measurement resources (IMR), and the mapping relationship between multiple sets of CMR and one set of IMR, determine a first Channel State Information (CSI) report. Here, each set of CMR includes one or more CMR, and each set of IMR includes one or more IMR. One set of CMR corresponds to one TRP, one set of CMR corresponds to one target CSI report, and the first CSI report includes multiple target CSI reports. The first CSI report may be a CSI report related to a beam or a CSI report related to a Multi-Transmission / Reception Point (Multi-TRP, MTRP).
[0023] In this embodiment, the first CSI report is determined based on the mapping relationship between multiple sets of CMR and multiple sets of IMR, and / or the mapping relationship between multiple sets of CMR and one set of IMR. The IMR does not have to correspond one-to-one with the CMR. That is, the number of IMR may be less than the number of CMR, thereby saving the deployment overhead of the IMR.
[0024]
[0025] In the above, when the first CSI report corresponds to one CSI reporting configuration, if a plurality of CMRs are mapped to one IMR, the first CSI report is further determined based on a plurality of quasi-collocation QCL information of the IMR or a plurality of transmission configuration indicator TCI states.
[0026] In the embodiments of this application, all descriptions of "if xxxx, then yyyy" may be understood as "when xxxx, execute yyyy". For example, in the above, "when the first CSI report corresponds to one CSI reporting configuration, if a plurality of CMRs are mapped to one IMR, the first CSI report is further determined based on a plurality of quasi-collocation QCL information of the IMR or a plurality of transmission configuration indicator TCI states" may be understood as "when the first CSI report corresponds to one CSI reporting configuration and a plurality of CMRs are mapped to one IMR, the first CSI report is further determined based on a plurality of quasi-collocation QCL information of the IMR or a plurality of transmission configuration indicator TCI states".
[0027] In a mapping relationship where a plurality of sets of CMRs correspond to a plurality of sets of IMRs, or a plurality of sets of CMRs correspond to one set of IMRs, if a plurality of CMRs are mapped to one IMR, the first CSI report is further determined based on a plurality of quasi-collocation (Quasi-co-located, QCL) information of the IMR or a plurality of transmission configuration indicator (Transmission Configuration Indicator, TCI) states.
[0028] The QCL information or TCI state includes one or more of QCLtypeA, QCLtypeB, QCLtypeC, and QCLtypeD.
[0029] In the above, the mapping relationship between the plurality of sets of CMRs and the plurality of sets of IMRs includes being mapped one-to-one between the plurality of sets of CMRs and the plurality of sets of IMRs, Here, for the first set of CMRs and the first set of IMRs having a mapping relationship, the CMRs among the first set of CMRs are one-to-one mapped with the IMRs among the first set of IMRs, or a plurality of CMRs among the first set of CMRs are mapped to one IMR among the first set of IMRs. The first set of CMRs is one set among the plurality of sets of CMRs, and the first set of IMRs is one set among the plurality of sets of IMRs.
[0030] That is, for a set of CMRs and a set of IMRs having a mapping relationship, the CMRs and IMRs within the group may be one-to-one mapped. That is, the CMRs among the first set of CMRs may be one-to-one mapped with the IMRs among the first set of IMRs, or may be multiple-to-one mapped. That is, a plurality of CMRs among the first set of CMRs are mapped to one IMR among the first set of IMRs. Preferably, the one-to-one mapping relationship between the plurality of sets of CMRs and the plurality of sets of IMRs may be applied when the first CSI report corresponds to one CSI reporting setting.
[0031] The mapping method between each group may be the same or different. For example, group A1 and group A2 are both CMR groups, group B1 and group B2 are both IMR groups, group A1 is mapped with group B1, and group A2 is mapped with group B2. For group A1 and group B1, the CMRs and IMRs within the group may be one-to-one mapped or multiple-to-one mapped. For group A2 and group B2, the CMRs and IMRs within the group may be one-to-one mapped or multiple-to-one mapped.
[0032] In the above case, when the CMRs in the first set of CMRs are one-to-one mapped to the IMRs in the first set of IMRs, the QCL information of the IMRs in the first set of IMRs is the same as the QCL information of the mapped CMRs, or the TCI state of the IMRs in the first set of IMRs is the same as the TCI state of the mapped CMRs. Here, the IMR is a Non-Zero Power Channel State Information-Reference Signal (NZP CSI-RS) IMR or a Channel State Information Interference Measurement (CSI-IM) IMR.
[0033] In the above case, the mapping relationship between the multiple sets of CMRs and one set of IMRs is including that multiple sets of CMRs are mapped to the second set of IMRs, where, for the second set of CMRs and the second set of IMRs having a mapping relationship, the CMRs in the second set of CMRs are one-to-one mapped to the IMRs in the second set of IMRs, or a plurality of CMRs in the second set of CMRs are mapped to one IMR in the second set of IMRs, and the second set of CMRs is one set among the multiple sets of CMRs.
[0034] That is, there is a mapping relationship between multiple sets of CMRs and the same set of IMRs. For one set of CMRs and multiple sets of IMRs having a mapping relationship, the CMRs and IMRs within the group may be one-to-one mapped. That is, the CMRs in the second set of CMRs may be one-to-one mapped to the IMRs in the second set of IMRs or may be mapped in a multiple-to-one manner. That is, a plurality of CMRs in the second set of CMRs are mapped to one IMR in the second set of IMRs. Preferably, the mapping relationship in which the multiple sets of CMRs are mapped to the second set of IMRs may be applied when the first CSI report corresponds to one CSI reporting setting.
[0035] The mapping methods between groups may be the same or different. For example, both Group A1 and Group A2 are CMR groups, Group B1 is an IMR group, Group A1 is mapped to Group B1, and Group A2 is mapped to Group B1. For Group A1 and Group B1, the CMR and IMR within the group may be mapped one-to-one or many-to-one. For Group A2 and Group B1, the CMR and IMR within the group may be mapped one-to-one or many-to-one.
[0036] In one embodiment of the present application, the mapping relationship between the plurality of sets of CMR and one set of IMR is including that a plurality of sets of CMR are mapped to a third set of IMR, when the CMR among each set of CMR and the IMR among the third set of IMR are all mapped one-to-one, the IMR among the third set of IMR has a plurality of QCL information or a plurality of TCI states, wherein, one QCL information among the plurality of QCL information is the same as the QCL information of one CMR among each set of CMR, different QCL information of the IMR corresponds to different CMR, one TCI state among the plurality of TCI states is the same as the TCI state of one CMR among each set of CMR, and different TCI states of the IMR correspond to different CMR. The IMR among the third set of IMR may be a CSI-IM IMR. Preferably, the mapping relationship between the plurality of sets of CMR and the third set of IMR may be applied when the first CSI report corresponds to one CSI reporting setting.
[0037] For example, both Group A1 and Group A2 are CMR groups, Group B1 is an IMR group, and Group A1 and Group A2 are each mapped to Group B1. Here, Group A1 includes CMR1 and CMR2, Group A2 includes CMR3 and CMR4, and Group B1 includes IMR1 and IMR2. There is a mapping relationship between each of CMR1 and CMR3 and IMR1, and there is a mapping relationship between each of CMR2 and CMR4 and IMR2.
[0038] Both IMR1 and IMR2 have a plurality of QCL information or a plurality of TCI states. The first QCL information among the plurality of QCL information of IMR2 is the same as the QCL information of CMR1, the second QCL information among the plurality of QCL information of IMR2 is the same as the QCL information of CMR2, and the first QCL information and the second QCL information are different QCL information among the plurality of QCL information of IMR2.
[0039] That is, when the first CSI report corresponds to one CSI reporting setting, the first CSI report may be determined based on the following mapping relationship. A plurality of CMR groups are mapped to a set of CSI-IM IMRs, and the CMRs within each CMR group and the IMRs within the IMR group are one-to-one mapped, that is, a plurality of CMRs from different CMR groups are mapped to the same IMR, and the IMR has a plurality of QCL information or TCI states. Here, each QCL information or TCI state coincides with the QCL information or TCI state of one corresponding CMR, and different QCL information or TCI states of the IMR correspond to different CMRs.
[0040] In one embodiment of the present application, when the first CSI report corresponds to one CSI reporting setting, the first CSI report includes at least one reporting parameter among CRI, PMI, RI, CQI, RSRP, SINR, LI, I1, and SSBRI, The reporting parameter is determined by RRC configuration, The number of control resource set pool indexes in the PDCCH configuration, or determined by the number of the control resource set pool indexes and the index values of the control resource set pool indexes, Determined by the content related to the number of reports newly added to the CSI report configuration, Determined by at least one of the methods of being determined by a field newly added to the CSI report configuration for indicating the number of reports.
[0041] In the above, the number of channel state information resource indicators (CSI-RS Resource Indicator, CRI), precoding matrix indicators (Precoding Matrix Indicator, PMI), rank indicators (Rank Indicator, RI), channel quality indicators (Channel quality indicator, CQI), reference signal received power (ReferenceSignal Received Power, RSRP), signal to interference noise ratio (signal to interference noise ratio, SINR), layer indicators (Layer Indicator, LI), composite codebook indexes (The composite codebook index, I1) and synchronization signal block resource indicators (SSB Resource Indicator, SSBRI) (synchronization signal block (Synchronization Signal Block, SSB)) may be one or more.
[0042] The reporting parameters may be determined by radio resource control (RRC) signaling configuration, or may be configured by a higher layer parameter physical downlink control channel (PDCCH) configuration (PDCCH-Config). The reporting parameters may further be determined by the content related to the number of reports newly added to the CSI report configuration, or may be determined by a field newly added to the CSI report configuration for indicating the number of reports.
[0043] Specifically, it may be determined by the control resource set pool index value (CORESETPoolIndex) and the number in the higher layer parameter PDCCH configuration (i.e., PDCCH-Config).
[0044] When determined based on the PDCCH configuration, if the PDCCH configuration includes one control resource set pool index, or if the PDCCH configuration does not include a control resource set pool index, the number of each parameter among the reporting parameters included in the target CSI report may be the same or different. For example, when the PDCCH configuration includes one CORESETPoolIndex or no CORESETPoolIndex is configured, one CSI report may include one CRI, one CQI, one RI, and two PMIs, or two CRIs, one CQI, two RIs, and two PMIs.
[0045] Alternatively, if the PDCCH configuration includes a plurality of control resource set pool indices and the index values of each control resource set pool index are different, the number of each parameter among the reporting parameters included in the target CSI report is the same as the number of the control resource set pool indices, or the number of each parameter among the reporting parameters included in the target CSI report is the same as the number of TRPs. For example, if the PDCCH configuration includes two or more CORESETPoolIndices with different values, one CSI report may include two CRIs, two PMIs, two RIs, and two CQIs.
[0046] The reporting parameters are determined by the content related to the number of reports newly added to the CSI report configuration. For example, the content of the upper layer parameter (i.e., reportQuantity) in the CSI report configuration (i.e., CSI-ReportConfig) can be added, and some special content, such as one CRI, one CQI, one RI, and two PMIs, or two CRIs, one CQI, two RIs, and two PMIs, or two CRIs, two CQIs, two RIs, and two PMIs, etc., can be added to support MTRP CSI.
[0047] The reporting parameters are determined by a field newly added to the CSI report configuration to indicate the number of reports. For example, in the CSI report configuration (i.e., CSI-ReportConfig), a new field can be added to support the selection of the number of MTRP CSIs. For example, a new report Quantity-mtrp field can be added to support various configurations such as one CRI, one CQI, one RI, and two PMIs, or two CRIs, one CQI, two RIs, and two PMIs, two CRIs, or two CQIs, two RIs, and two PMIs.
[0048] In the above, each reporting parameter may be arranged in two or more to better support MTRP transmission.
[0049] In one embodiment of the present application, when N CMRs are mapped to one IMR, if there is no measurement timing of the interference measurement resource among the N CMRs, the IMR corresponding to the N CMRs is determined by mapping the interference measurement resources on the nearest N measurement timings to the N CMRs according to a first preset rule, where N is an integer greater than 1, or, when N CMRs are mapped to one IMR, if there is a measurement timing of the interference measurement resource among the N CMRs, the IMR corresponding to the first CMR among the N CMRs is the interference measurement resource on the nearest measurement timing that has not been mapped by other CMRs before the first CMR, and the IMR corresponding to the nth CMR among the N CMRs is the interference measurement resource on the nearest measurement timing that has not been mapped by other CMRs before the nth CMR, where n is an integer greater than 1 and less than or equal to N. The appearance order of the (n - 1)th CMR is earlier than that of the nth CMR, and the order of the measurement timings mapped by the N CMRs is from the Nth CMR to the first CMR. That is, when determining the IMRs corresponding to the N CMRs, first, determine the IMR corresponding to the CMR that appears the latest, and then, in the descending order of the appearance time of the CMRs, determine the IMR corresponding to each CMR.
[0050] In the above, the first preset rule is that the IMR corresponding to the CMR among the N CMRs is in one-to-one correspondence with the interference measurement resources on each of the nearest N measurement timings.
[0051] For example, when two CMRs are mapped to the same IMR, if there is no measurement timing of the interference measurement resource between the two CMRs, the IMRs corresponding to the two CMRs may be determined by mapping the interference resources on the nearest two measurement timings to different channel measurement resources according to a certain rule.
[0052] The first preset rule may be as follows. It is determined based on the appearance order of two CMRs. That is, the IMR corresponding to the first CMR is the first measurement timing among the two most recent measurement timings, and the IMR corresponding to the second CMR is the second measurement timing among the two most recent measurement timings. Or, the IMR corresponding to the first CMR may be the second measurement timing among the two most recent measurement timings, and the IMR corresponding to the second CMR may be the first measurement timing among the two most recent measurement timings. Specifically, it may be flexibly set according to the actual situation and is not limited here.
[0053] When there is a measurement timing of an interference measurement resource between two CMRs, the measurement timing of the IMR corresponding to the first CMR is the IMR at the most recent measurement timing before the first CMR, and the measurement timing of the IMR corresponding to the second CMR is the most recent measurement timing between the two CMRs.
[0054] When the first CSI report corresponds to one CSI reporting setting, the usage method of the multiple QCL information of the IMR includes that one measurement timing uses one QCL information, or one measurement timing uses multiple QCL information.
[0055] The usage of the QCL information of the IMR includes two cases: one measurement timing uses one QCL information, and one measurement timing uses multiple QCL information, and each QCL information may correspond to a different UE antenna panel or antenna port.
[0056] In one embodiment of the present application, when M CMRs are mapped to one IMR, if there is no measurement timing of the interference measurement resource among the M CMRs, the QCL information of the IMR corresponding to the M CMRs is obtained by mapping the interference measurement resources on the latest M measurement timings to the M CMRs according to a second preset rule. Here, M is an integer greater than 1. Or When M CMRs are mapped to one IMR, if there is a measurement timing of the interference measurement resource among the M CMRs, the QCL information of the IMR corresponding to the first CMR among the M CMRs is determined based on the interference measurement resource on the latest measurement timing that has not been mapped by other CMRs before the first CMR. And the QCL information of the IMR corresponding to the m-th CMR among the M CMRs is determined based on the interference measurement resource on the latest measurement timing that has not been mapped by other CMRs before the m-th CMR. Here, m is an integer greater than 1 and less than or equal to M. The appearance order of the (m - 1)-th CMR is earlier than that of the m-th CMR. The order of the measurement timings mapped by the M CMRs is from the M-th CMR to the first CMR. That is, when determining the IMRs corresponding to the M CMRs, first, determine the IMR corresponding to the CMR that appears the latest, and then, in the order of the later appearance time of the CMRs, determine the IMR corresponding to each CMR.
[0057] The second preset rule is that the IMR corresponding to the CMR among the M CMRs has a one-to-one correspondence with the interference measurement resources on each of the latest M measurement timings.
[0058] For example, when two CMRs are mapped to the same IMR, if there is no measurement timing of the interference measurement resource between the two CMRs, the QCL information of the IMRs corresponding to the two CMRs may be determined by mapping the interference resources on the latest two measurement timings to different channel measurement resources according to a certain rule.
[0059] The second preset rule may be as follows. It is determined based on the order of appearance of the two CMRs. That is, the IMR corresponding to the first CMR is the first measurement timing among the two most recent measurement timings, and the IMR corresponding to the second CMR is the second measurement timing among the two most recent measurement timings. Or, the IMR corresponding to the first CMR may be the second measurement timing among the two most recent measurement timings, and the IMR corresponding to the second CMR may be the first measurement timing among the two most recent measurement timings. Specifically, it may be flexibly set according to the actual situation and is not limited here.
[0060] When there is a measurement timing of the interference measurement resource between two CMRs, the measurement timing of the IMR corresponding to the first CMR is the IMR at the most recent measurement timing before the first CMR, and the measurement timing of the IMR corresponding to the second CMR is the most recent measurement timing between the two CMRs.
[0061] In one embodiment of the present application, after determining the first channel state information CSI report, the method further includes transmitting a second CSI report, the second CSI report includes a first target CSI report and a second target CSI report, the first target CSI report is an unselected target CSI report among the plurality of target CSI reports included in the first CSI report, and the second target CSI report is a selected target CSI report among the plurality of target CSI reports.
[0062] This embodiment may be applied when the first CSI report corresponds to one CSI reporting setting, and may also be applied when the first CSI report corresponds to a plurality of CSI reporting settings.
[0063] One target CSI report corresponds to one TRP, and the terminal can make a selection for the TRP that it desires to participate in its scheduling based on the target CSI report. If the terminal does not desire to be scheduled by a certain CSI by the TRP or does not desire to be scheduled by a certain TRP, the terminal may set the CQI index value of the corresponding CSI or the target CSI of the corresponding TRP to 0 when generating the target CSI report (specifically, refer to the following description). After the target CSI report is decoded by the network-side device, if the CQI index value corresponding to the target CSI is 0, it means that the terminal does not desire the network-side device to use this CSI for scheduling or does not desire to participate in the scheduling of the TRP corresponding to this target CSI.
[0064] The first target CSI report is a target CSI report corresponding to the TRP that the terminal is not desired to participate in the selection, and the second target CSI report is a target CSI report corresponding to the TRP that the terminal is desired to participate in the selection. The second CSI report may include only some content of the first target CSI report, for example, only the content of the first part (part1). The second CSI report may include the first part of the second target CSI report and the content of other parts other than the first part of the second target CSI report. For example, if the second target CSI report includes a first part (part1) and a second part (part2), the second CSI report may include the first part and the second part of the second target CSI report. That is, the second CSI report may include the first part of the first target CSI report and / or all the content of the second target CSI report.
[0065] In the above, when determining selection and non - selection, it may be instructed based on the first part in the target CSI report. That is, when at least one of the following conditions is included in the first part of the first target CSI report: the CQI index value is 0 or a first specified value, the RI index value is 0 or a second specified value, the state of CSI indicated by the bitmap is a first state, the TRP corresponding to the first target CSI report is not selected, and the terminal indicates that it does not desire the scheduling of this TRP by the network - side device.
[0066] When at least one of the following conditions is included in the first part of the second target CSI report: the CQI index value is not 0 and not the first specified value, the RI index value is not 0 and not the second specified value, CRI, the state of CSI indicated by the bitmap is a second state, the TRP corresponding to the second target CSI report is selected, and the terminal indicates that it desires the scheduling of this TRP by the network - side device.
[0067] Specifically, if the CQI index value in the first part is 0 (i.e., OOR) or the first specified value, the terminal has not selected the current target CSI. That is, the terminal does not wish to participate in the scheduling of the TRP corresponding to this target CSI, or it means that the network-side device does not wish to schedule using the CSI with a CQI index value of 0. And when the CQI index value is 0 and this target CSI includes two or more parts, the terminal does not report parts other than part1. If the CQI index value in the first part is not 0 (i.e., OOR) or the first specified value, the terminal has selected the current target CSI. That is, the terminal wishes to participate in the scheduling of the TRP corresponding to this target CSI, or it means that the network-side device wishes to schedule using the CSI with a CQI index value other than 0. And when the CQI index value is 0 and this target CSI includes two or more parts, the terminal reports part1 and also reports other parts.
[0068] If the RI in the first part is 0 or the second specified value, the terminal has not selected the current target CSI. That is, the terminal does not wish to participate in the scheduling of the TRP corresponding to this target CSI, or it means that the network-side device does not wish to schedule using the CSI with an RI of 0. And when this target CSI includes two or more parts, the terminal does not report parts other than part1. If the RI in the first part is not 0 or the second specified value, the terminal has selected the current target CSI. That is, the terminal wishes to participate in the scheduling of the TRP corresponding to this target CSI, or it means that the network-side device wishes to schedule using the CSI with an RI other than 0. And when this target CSI includes two or more parts, the terminal reports part1 and also reports other parts.
[0069] If one or more CRIs are reported in the first part, it means that the terminal has selected the CSI corresponding to the current one or more CRIs. And if the unselected CSI contains two or more parts, the terminal does not report parts other than part1.
[0070] Explicitly indicate the CSI state included in the current report in part1 by bitmap mapping. If the bit corresponding to the target CSI is invalid, for example 0, that is, in the first state, it means that the terminal has not selected this target CSI, that is, the terminal does not wish to participate in the scheduling of the TRP corresponding to the CSI with bit 0, or the network-side device does not wish to schedule using the CSI with bit 0. And if the target CSI with bit 0 contains two or more parts, the terminal does not report parts other than part1.
[0071] If the bit corresponding to the target CSI is valid, for example 1, that is, in the second state, it means that the terminal has selected this target CSI, that is, the terminal wishes to participate in the scheduling of the TRP corresponding to the CSI with bit 1, or the network-side device wishes to schedule using the CSI with bit 1. And if the target CSI with bit 1 contains two or more parts, in addition to reporting part1, the terminal also reports other parts.
[0072] In one embodiment of the present application, when the first CSI report corresponds to multiple CSI reporting settings, after determining the first channel state information CSI report, the method is to adopt a method of transmitting multiple times to transmit a third CSI report, where the third CSI report is determined based on the first target CSI report and the second target CSI report. Or Further including transmitting a coordinated CSI report including report parameters corresponding to the second target CSI report, Here, the first target CSI report is an unselected target CSI report among a plurality of target CSI reports included in the first CSI report, and the second target CSI report is a selected target CSI report among the plurality of target CSI reports.
[0073] Specifically, a method of reporting multiple times is adopted to transmit a third CSI report, and the third CSI report transmitted each time may be the same or different. The third CSI report may include some content of the first target CSI report and all content of the second target CSI report.
[0074] The report parameters included in the third CSI report may be determined based on the report parameters in the second target CSI report. Each CSI report setting may arrange a different number of report parameters. For example, when it is determined that it is necessary to report two PMIs, two RIs, and one CQI by adopting a method of reporting multiple times based on the second target CSI report, if two PMIs, two RIs, and one CQI are reported to two TRPs by two third CSI reports, in the CSI report setting corresponding to the first third CSI report, they may be arranged as one PMI, one RI, and one CQI, and in the CSI report setting corresponding to the second third CSI report, they may be arranged as one PMI and one RI. The CQI of the second third CSI report may be derived from the first third CSI report, and the two third CSI reports may be reported on different resources.
[0075] A reporting method may be adopted to report a single coordinated CSI report, which may include multiple PMIs, multiple CQIs, multiple RIs, etc. corresponding to multiple CSI reporting configurations. For example, if two target CSI reports are required to report two PMIs, two RIs, and one CQI to two TRPs, the two PMIs, two RIs, and one CQI may be reported on the reporting resources corresponding to the CSI reporting configuration corresponding to the first second target CSI report or the second second target CSI report.
[0076] In the above, the coordinated CSI report may include only the second target CSI report, or may include both the first target CSI report and the second target CSI report. For example, the coordinated CSI report may include the first part of the first target CSI report and / or all the contents of the second target CSI report.
[0077] In the above, when the multiple target CSI reports correspond to different PUCCH resources or PUSCH resources, a method of transmitting multiple times is adopted to transmit a third CSI report. When the multiple target CSI reports correspond to the same PUCCH resource or PUSCH resource, a coordinated CSI report is transmitted.
[0078] That is, the terminal can determine whether to report multiple target CSI reports respectively based on the configured Physical Uplink Control Channel (PUCCH) or Physical Uplink Shared Channel (PUSCH), or report a single coordinated CSI report. For example, when multiple CSI reporting configurations correspond to the same PUCCH resource or PUSCH resource, one coordinated CSI report is reported; when multiple CSI reporting configurations correspond to different PUCCH resources or PUSCH resources, they are reported separately based on their respective corresponding resources.
[0079] In this application, the network-side device is instructed by the target CSI report that the terminal does not want the TRP corresponding to the target CSI to participate in scheduling. Further, this application can better support the reporting of two or more reporting parameters in different MTRP transmission methods (for example, S-DCI, M-DCI). For example, reporting two CRIs, one CQI, two RIs, and two PMIs, etc. By instructing feedback instructions such as selection or non-selection in the first part of the target CSI report, the feedback overhead and the complexity of system scheduling can be reduced.
[0080] Figure 3 is a flowchart of a reporting setting determination method according to an embodiment of this application. This reporting setting determination method is executed by a network-side device and includes the following steps.
[0081] Step 301, Arrange a reporting setting including at least one mapping relationship between a plurality of sets of channel measurement resources CMR and a plurality of sets of interference measurement resources IMR, and a mapping relationship between a plurality of sets of CMR and one set of IMR, where each set of CMR includes one or more CMR, and each set of IMR includes one or more IMR.
[0082] In this embodiment, the reporting setting includes a mapping relationship between a plurality of sets of CMR and a plurality of sets of IMR, and / or a mapping relationship between a plurality of sets of CMR and one set of IMR. The IMR does not have to correspond one-to-one with the CMR. That is, the number of IMR may be less than the number of CMR, thereby saving the allocation overhead of the IMR.
[0083] In the above, each set of CMR among the plurality of sets of CMR corresponds to one transmission and reception point TRP or transmission configuration indicator TCI state, and the offsets of the plurality of sets of CMR are the same or different.
[0084] In one embodiment of the present application, the reporting setting determination method further includes receiving a CSI report including a first target CSI report not selected by the terminal and / or a second target CSI report selected by the terminal.
[0085] Furthermore, after receiving the CSI report, the method further includes not scheduling a TRP corresponding to the first target CSI, and / or scheduling a TRP corresponding to the first target CSI.
[0086] In the above, the first part of the first target CSI report includes at least one of: a channel quality indicator (CQI) index value being 0 or a first specified value; a rank indicator (RI) index value being 0 or a second specified value; a CSI state indicated by a bitmap being in a first state.
[0087] In the above, the first part of the second target CSI report includes at least one of: a CQI index value not being 0 and not being the first specified value; an RI index value not being 0 and not being the second specified value; a channel state information resource indicator (CRI); a CSI state indicated by a bitmap being in a second state.
[0088] Specifically, if the CQI index value in the first part is 0 (i.e., OOR) or the first specified value, it means that the terminal has not selected the current target CSI, that is, the terminal does not wish to participate in the scheduling of the TRP corresponding to this target CSI, or the network-side device does not wish to schedule using the CSI with a CQI index value of 0. And when the CQI index value is 0 and this target CSI includes two or more parts, the terminal does not report parts other than part1. If the CQI index value in the first part is not 0 (i.e., OOR) or the first specified value, the terminal has selected the current target CSI. That is, the terminal wishes to participate in the scheduling of the TRP corresponding to this target CSI, or the network-side device wishes to schedule using the CSI with a CQI index value not equal to 0. And when the CQI index value is not 0 and this target CSI includes two or more parts, the terminal reports part1 and also reports other parts.
[0089] If the RI in the first part is 0 or the second specified value, it means that the terminal has not selected the current target CSI, that is, the terminal does not wish to participate in the scheduling of the TRP corresponding to this target CSI, or the network-side device does not wish to schedule using the CSI with an RI of 0. And when this target CSI includes two or more parts, the terminal does not report parts other than part1. If the RI in the first part is not 0 or the second specified value, the terminal has selected the current target CSI. That is, the terminal wishes to participate in the scheduling of the TRP corresponding to this target CSI, or the network-side device wishes to schedule using the CSI with an RI not equal to 0. And when this target CSI includes two or more parts, the terminal reports part1 and also reports other parts.
[0090] If one or more CRIs are reported in the first part, it means that the terminal has selected the CSI corresponding to the current one or more CRIs. And if the unselected CSI contains two or more parts, the terminal does not report parts other than part1.
[0091] Explicitly indicate the CSI state included in the current report in part1 by bitmap mapping. If the bit corresponding to the target CSI is invalid, for example 0, i.e., in the first state, it means that the terminal has not selected this target CSI. That is, the terminal does not wish to participate in the scheduling of the TRP corresponding to the CSI with bit 0, or the network-side device does not wish to schedule using the CSI with bit 0. And if the target CSI with bit 0 contains two or more parts, the terminal does not report parts other than part1.
[0092] If the bit corresponding to the target CSI is valid, for example 1, i.e., in the second state, it means that the terminal has selected this target CSI. That is, the terminal wishes to participate in the scheduling of the TRP corresponding to the CSI with bit 1, or the network-side device wishes to schedule using the CSI with bit 1. And if the target CSI with bit 1 contains two or more parts, in addition to reporting part1, the terminal also reports other parts.

[0105] Furthermore, when N CMRs are mapped to one IMR, if there is no measurement timing of the interference measurement resource among the N CMRs, the IMR corresponding to the N CMRs is determined by mapping the interference measurement resources on the nearest N measurement timings to the N CMRs according to a first preset rule, where N is an integer greater than 1, or, when N CMRs are mapped to one IMR, if there is a measurement timing of the interference measurement resource among the N CMRs, the IMR corresponding to the first CMR among the N CMRs is the interference measurement resource on the nearest measurement timing that has not been mapped by other CMRs before the first CMR, and the IMR corresponding to the nth CMR among the N CMRs is the interference measurement resource on the nearest measurement timing that has not been mapped by other CMRs before the nth CMR, where n is an integer greater than 1 and less than or equal to N, the appearance order of the (n - 1)th CMR is earlier than that of the nth CMR, and the order of the measurement timings mapped by the N CMRs is from the Nth CMR to the first CMR.
