The wearable devices include: smart bracelets, earphones, glasses, etc.

[0025] To better understand the solution provided by the present application, the following content will be described first:

[0026] I. Multi-TRP transmission technology

[0027] In the multi-TRP / multi-panel scenario, the reliability and throughput performance of transmission can be increased. For example, a terminal (UE) can receive the same or different data from multiple TRPs. The multi-TRP can be divided into an ideal backhaul and a non-ideal backhaul. In the case of a non-ideal backhaul, there is a large delay in the interaction information between multi-TRPs, which is more suitable for independent scheduling. The acknowledgement (ACK) / negative acknowledgement (NACK) and CSI reports are fed back to each TRP respectively. It is usually applicable to multi-DCI scheduling, that is, each TRP sends its own Physical Downlink Control Channel (PDCCH), and each PDCCH schedules its own Physical Downlink Shared Channel (PDSCH). Multiple Control-Resource Sets (CORESETs) configured for the UE are associated with different RRC parameters CORESETPoolIndex, corresponding to different TRPs. Multiple Physical Downlink Shared Channels (PDSCHs) scheduled by multiple Downlink Control Information (DCI) may be non-overlapping, partially overlapping, or completely overlapping in time-frequency resources. In the overlapping time-frequency resources, each TRP performs independent precoding according to its own channel, and the UE receives multiple layers of data streams belonging to multiple PDSCHs in the manner of non-Coherent Joint Transmission (NCJT).

[0028] In the case of an ideal backhaul, the multi-TRPs can interact with scheduling information and the UE's feedback information in real time. In addition to the above multi-DCI scheduling of multiple PDSCHs, single-DCI scheduling of PDSCH is also possible, including the following transmission schemes:

[0029] Space Division Multiplexing (SDM): Different data layers of the same Transport Block (TB) come from the NCJT transmission of different TRPs

[0030] Frequency-Division Multiplexing (FDM): Different frequency-domain resources mapped by the same TB and the same Redundant version (RV) are sent from different TRPs, or different RVs of the same TB are mapped to different frequency-domain resources and concurrently sent from different TRPs

[0031] Time-Division Multiplexing (TDM): Multiple repetitions of different RVs of the same TB come from different TRPs, for example, repetitions within one time slot or repetitions in multiple time slots.

[0032] At this time, ACK / NACK feedback and CSI reports can be fed back to any one of the TRPs.

[0033] II. CSI Framework for a Single TRP

[0034] CSI reports can be configured as follows:

[0035] (1) Periodic CSI report (P-CSI): Transmitted only on PUCCH;

[0036] (1) Semi-persistent CSI report (SP-CSI): Transmitted on PUCCH or PUSCH;

[0037] (1) Aperiodic CSI report (A-CSI): Transmitted only on PUSCH;

[0038] CSI resource configuration (resource setting / CSI-ResourceConfig) is as follows:

[0039] (1) M ≥ 1 resource configurations (resource setting);

[0040] (2) One resource configuration contains S ≥ 1 CSI resource indicator (CSI-RS Resource Indicator, CSI-RS) resource sets (resource set);

[0041] (3) One resource set contains Ks ≥ 1 RS resources (resource), such as CSI-RS / CSI interference measurement (CSI-Interference Measurement, CSI-IM) resources;

[0042] (4) One CSI-RS resource is used to configure information such as the number of ports and time-frequency location of CSI-RS; one CSI-IM resource is used to configure information such as the time-frequency location of CSI-IM.

[0043] III. Potential CSI Framework for Multiple TRPs

[0044] Specific definitions are made for multiple TRPs / multiple panels in terms of CSI report configuration and CSI resource configuration, etc., including the following methods:

[0045] (1) Configure multiple CSI report settings (CSI-ReportConfig), where the resource setting (CSI-ResourceConfig) of each report setting corresponds to a TRP, that is, each CSI report setting corresponds to a CSI report of a TRP.

[0046] (2) When configuring the CSI report of a CSI report setting for multiple TRPs, the UE needs to measure the CSI-RS from different TRPs. Therefore, within one CSI report setting

[0047] (2.1) Associate multiple groups of CSI resource settings that respectively correspond to different TRPs. Each group of CSI resource settings includes one or more CSI resource settings in the CSI resource setting for channel measurement, interference measurement, and interference measurement of non-zero power CSI-RS; or

[0048] (2.2) The associated CSI resource setting contains S > 1 (specifying a periodic or semi-persistent resource setting, S = 1) CSI resource sets, and each CSI resource set corresponds to a different TRP (with different Quasi Co Location (QCL));

[0049] (2.3) The CSI resource set within the associated CSI resource setting contains multiple subsets, and each subset contains multiple CSI resources, corresponding to a TRP.

[0050] IV. Non Zero Power Channel State Information Reference Signal (NZP-CSI RS)

[0051] Indicated by the higher layer parameters CSI-ResourceConfig and NZP-CSI-RS-ResourceSet, the UE can configure one or more NZP CSI-RS resource set configurations, and each NZP CSI-RS resource set consists of K ≥ 1 NZP CSI-RS resource(s).

[0052] Except for the NZP CSI-RS resources used for interference measurement, the CSI-RS resources in the same resource set are configured with the same density and the same number of ports. The UE expects that all CSI-RS resources in a resource set are configured with the same starting RB, the same number of RBs, and the same cdm type.

[0053] The UE may assume that one or more NZP CSI-RS resources used for channel measurement and one or more CSI-IM resources used for interference measurement or multiple NZP CSI-RS resources used for interference measurement in a report config have a QCL relationship of 'QCL-TypeD' at the resource level.

[0054] The UE may assume that one or more NZP CSI-RS resources used for channel measurement and one or more CSI-IM resources used for interference measurement in a report config have a QCL relationship of 'QCL-TypeD' at the resource level.

[0055] If NZP CSI-RS is used for interference measurement, the UE does not expect more than one NZP CSI-RS resource for channel measurement and does not expect more than 18-port NZP CSI-RS configured for interference measurement in a NZP CSI-RS resource set.

[0056] V. Resource Setting Configuration

[0057] (1) For aperiodic CSI, each CSI-ReportConfig can configure one or more periodic, semi-persistent, or aperiodic resource settings:

[0058] When one resource setting is configured, the resource setting is used for L1-RSRP channel measurement or channel and interference measurement of L1-SINR;

[0059] When two resource settings are configured, the first resource setting is used for channel measurement. The second resource setting is used for interference measurement (which can be based on CSI-IM or NZP CSI-RS);

[0060] When three resource settings are configured, the first resource setting is used for channel measurement. The second resource setting is used for interference measurement based on CSI-IM. The third resource setting is used for interference measurement based on NZP CSI-RS;

[0061] (2) For periodic or semi-persistent CSI, each CSI-ReportConfig can configure one or more periodic, semi-persistent resource settings:

[0062] When configuring a resource setting, the resource setting is used for L1-RSRP channel measurement or channel and interference measurement of L1-SINR;

[0063] When configuring two resource settings, the first resource setting is used for channel measurement. The second resource setting is used for CSI-IM interference measurement (when measuring L1-SINR, it can also be interference measurement based on NZP CSI-RS);

[0064] (3) For CSI measurements other than L1-SINR, the terminal assumes that each NZP CSI-RS port used for interference measurement corresponds to an interference transmission layer.

[0065] NZP-IMR (NZP interference measurement resource) is used to calculate inter-layer interference. The UE does not assume that PMI is obtained using NZP-IMR and then calculate the inter-layer interference of MTRP transmission. Therefore, how to use NZP-IMR to calculate the CS of multiple TRPs needs further research and optimization.

[0066] The following combines the accompanying drawings and details the CSI measurement method provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0067] See Figure 1 , the embodiments of the present application provide a CSI measurement method, which is executed by a terminal, and the method includes:

[0068] Step 101: Obtain first CSI report configuration information from the network side, where the first CSI report configuration information is used to configure CMR and IMR;

[0069] Step 102: Perform MTRP CSI calculation according to the first CSI report configuration information;

[0070] In the embodiments of the present application, during MTRP transmission, the network side configures channel measurement resources (Channel Measurement Resource, CMR) and interference measurement resources (Interference Measurement Resource, IMR) through the first CSI report configuration information (First CSI-Report Config). Among them, IMR is configured as CSI-Interference Measurement (CSI-IM) resources and / or interference measurement NZP CSI-RS resources. Optionally, the interference measurement NZP CSI-RS resources can be referred to as NZP CSI-RS for interference resources. When IMR is configured as interference measurement NZP CSI-RS resources, IMR can also be referred to as NZP-IMR.

[0071] In some embodiments, the terminal configures or indicates (explicitly or implicitly) a first CSI-Report Config through the network side.

[0072] Optionally, CMR and IMR can be configured through the resourcesForChannelMeasurement field and the nzp-CSI-RS-ResourcesForInterference field in the first CSI-Report Config.

[0073] In the embodiments of the present application, the network side configures CMR and IMR for the terminal through the first CSI report configuration information, where the IMR is configured as CSI-IM resources and / or interference measurement NZP CSI-RS resources. The terminal performs MTRP CSI calculations according to the first CSI report configuration information, and realizes a method for calculating MTRP CSI using CSI-IM resources and / or interference measurement NZP CSI-RS resources, which can make greater use of the CSI framework.

[0074] In some embodiments, before performing MTRP CSI calculations, the method further includes:

[0075] Determine the QCL information of the interference measurement NZP CSI-RS resources through higher layer signaling.

[0076] In the embodiments of the present application, the QCL information of the NZP IMR is obtained according to the indication of higher layer signaling.

[0077] Specifically, determining the QCL information of the interference measurement NZP CSI-RS resources through higher layer signaling includes at least one of the following:

[0078] (1) If the interference measurement NZP CSI-RS resources are periodic resources, semi-persistent resources or aperiodic resources, determine the QCL information according to the target parameter field in the higher layer parameters configuring the interference measurement NZP CSI-RS resources; optionally, it can be obtained according to the qcl-InfoPeriodicCSI-RS in the higher layer parameter NZP-CSI-RS-Resource configuring the IMR, or obtained according to other fields (which can be newly added fields) of the higher layer parameter NZP-CSI-RS-Resource configuring the IMR.

[0079] (2) If the interference measurement NZP CSI-RS resources are aperiodic resources, determine the QCL information according to the downlink control information DCI;

[0080] The terminal can also determine the QCL information according to the resource configuration method or the content to be reported, specifically as follows:

[0081] (3) If the interference measurement NZP CSI-RS resource is configured as the CMR of another cell (for example, the interference measurement NZP CSI-RS resource of TRP1 is configured as the CMR of TRP2), determine the QCL information according to the target parameter field or DCI in the higher-layer parameters for configuring the interference measurement NZP CSI-RS resource, that is, if the IMR of the terminal is configured as another reported CMR, the QCL information should be determined in the manner described in (1).

[0082] (4) If the content to be reported is related to MTRP CSI, determine the QCL information according to the target parameter field or DCI in the higher-layer parameters for configuring the interference measurement NZP CSI-RS resource. When the network side instructs the terminal to report MTRP CSI corresponding to a certain reporting setting, at this time the terminal needs to calculate the content related to MTRP CSI using the reporting setting. If the reporting setting configures NZP-IMR, the terminal needs to determine the QCL information of NZP-IMR according to the target parameter field or DCI in the higher-layer parameters, and then calculate MTRP-CSI with the CMR in the reporting setting.

[0083] In some embodiments, when the terminal obtains the first CSI-Report Config for MTRP CSI calculation through network-side configuration or indication (explicit or implicit) and the first CSI-Report Config configures the NZP CSI-RS for interference measurement (NZP-IMR), the MTRP CSI calculation process is as follows:

[0084] (1) If it is non-precoding matrix indicator (non-PMI) transmission, determine the PMI corresponding to the interference measurement NZP CSI-RS resource as the identity matrix; precode the interference measurement NZP CSI-RS resource through the PMI corresponding to the interference measurement NZP CSI-RS resource; and correspond each port of each precoded interference measurement NZP CSI-RS resource to an interference transmission layer.

[0085] In the embodiments of the present application, for the non-PMI transmission case, the terminal assumes that the PMI corresponding to the NZP-IMR is the identity matrix, and precodes the NZP-IMR using the PMI of the NZP-IMR. The terminal assumes that each port of the precoded NZP-IMR corresponds to an interference transmission layer; where the non-PMI transmission case refers to the configuration of the high-layer parameter non-PMI-PortIndication in the high-layer parameter CSI-ReportConfig.

[0086] (2) If it is non-non-PMI transmission, calculate the PMI according to the interference measurement NZP CSI-RS resource; precode the interference measurement NZP CSI-RS resource using the PMI corresponding to the interference measurement NZP CSI-RS resource; and correspond each port of the precoded interference measurement NZP CSI-RS resource to an interference transmission layer.

[0087] In the embodiments of the present application, for the non-non-PMI transmission case, the terminal needs to calculate the PMI according to the interference measurement of the NZP-IMR, precode the NZP-IMR using the PMI of the NZP-IMR, and the terminal assumes that each port of the precoded NZP-IMR corresponds to an interference transmission layer.

[0088] In some embodiments, the method further includes: performing interference measurement according to the IMR, that is, the interference measurement behavior for the interference measurement resource. Specifically as follows:

[0089] 1. When the IMR is configured as a CSI-IM resource, perform interference measurement according to the IMR, including at least one of the following:

[0090] (1) If the CSI-IM resources of multiple associated reporting settings are the same, calculate the interference of the CSI-IM part according to the result measured from the CSI-IM resource;

[0091] (2) If multiple associated reporting settings are used for CSI calculation, the terminal expects that the CSI-IM resources corresponding to the multiple reporting settings are the same, and calculate the interference of the CSI-IM part according to the result measured from the CSI-IM resource; the network side configures multiple associated reporting settings to calculate CSI, and the terminal can consider that the CSI-IM resources corresponding to the multiple reporting settings are the same, or it can be understood that the terminal does not expect the CSI-IM resources corresponding to multiple associated reporting settings configured by the base station to be different.

[0092] (3) If the CSI-IM resources of multiple associated reporting settings are different, average, sum, take the maximum value or take the minimum value of the results measured from the CSI-IM resources;

[0093] (4) If the CSI-IM resources corresponding to multiple associated CMRs are the same, calculate the interference of the CSI-IM part based on the results measured according to the CSI-IM resources;

[0094] (5) If multiple associated CMRs perform CSI calculation and the terminal expects the CSI-IM resources corresponding to the multiple CMRs to be the same, calculate the interference of the CSI-IM part based on the results measured according to the CSI-IM resources; It should be noted that the difference between (5) and (4) is that in (4), the CSI-IM resources corresponding to the configured multiple CMRs are the same, while in (5), the terminal expects the CSI-IM resources corresponding to the multiple CMRs to be the same.

[0095] (6) If the CSI-IM resources corresponding to multiple associated CMRs are different, average, sum, take the maximum value, or take the minimum value of the results obtained from the measurement of the CSI-IM resources.

[0096] 2. The IMR is configured to interfere with the measurement of NZP CSI-RS resources. According to the IMR, perform interference measurement, including at least one of the following:

[0097] (1) If the NZP CSI-RS resources for interference measurement set by multiple associated reports are the same, calculate the interference of the NZP CSI-RS part for interference measurement based on the results measured according to the NZP CSI-RS resources for interference measurement;

[0098] (2) If multiple associated reports are set for CSI calculation and the terminal expects the NZP CSI-RS resources for interference measurement of the multiple reports to be the same, calculate the interference of the NZP CSI-RS part for interference measurement based on the results measured according to the NZP CSI-RS resources for interference measurement;

[0099] (3) If the NZP CSI-RS resources for interference measurement set by multiple associated reports are different, perform interference measurement on the different NZP CSI-RS resources for interference measurement respectively according to the QCL information of the corresponding CMR, and average, take the maximum value, or sum the measurement results;

[0100] (4) If the NZP CSI-RS resources for interference measurement of multiple associated CMRs are the same, calculate the interference of the NZP CSI-RS part for interference measurement based on the results measured according to the NZP CSI-RS resources for interference measurement;

[0101] (5) If multiple associated CMRs perform CSI calculation and the terminal expects the NZP CSI-RS resources for interference measurement corresponding to the multiple CMRs to be the same, calculate the interference of the NZP CSI-RS part for interference measurement based on the results measured according to the NZP CSI-RS resources for interference measurement;

[0102] (6) If the interference measurement NZP CSI-RS resources of multiple associated CMRs are different, perform interference measurements on the different interference measurement NZP CSI-RS resources according to the QCL of the corresponding CMRs respectively, and average, take the maximum or sum the measurement results;

[0103] (7) Calculate the interference on the interference measurement NZP CSI-RS resources for a preset PMI. The terminal uses the preset or network-indicated PMI to act on the interference measurement NZP CSI-RS resources and calculates the interference of the interference measurement NZP CSI-RS part.

[0104] In some embodiments, when the terminal obtains the first CSI-Report Config for MTRP CSI calculation through network-side configuration or indication (explicit or implicit) and the first CSI-Report Config configures the NZP CSI-RS (NZP-IMR) for interference measurement, the terminal can support NZP CSI-RS with more than 18 ports for interference measurement;

[0105] In some embodiments, when the terminal obtains the first CSI-Report Config for MTRP CSI calculation through network-side configuration or indication (explicit or implicit) and if the first CSI-Report Config is periodic or semi-persistent, when two resource settings are configured, the first resource setting is used for channel measurement; the second resource setting is used for interference measurement based on CSI-IM or interference measurement based on NZP CSI-RS;

[0106] In some embodiments, when the first CSI-Report Config obtained by the terminal through network-side configuration is periodic or semi-persistent, if the first CSI-Report Config configures the NZP CSI-RS for interference measurement, the terminal assumes that the first CSI-Report Config is used for MTRP CSI calculation;

[0107] In some embodiments, characterized in that before performing MTRP CSI calculation, the method further includes: measuring M CMRs associated with N MTRP measurement hypotheses, where N is less than M and is a positive integer, and each MTRP measurement hypothesis is associated with at least 2 CMRs.

[0108] For a measurement hypothesis, the terminal does not expect at least one of the following situations:

[0109] There is more than or equal to 1 uplink transmission symbol between the measurement times of multiple CMRs associated with any one of the N MTRP measurement hypotheses measured;

[0110] There is an uplink time slot between the measurement times of multiple CMRs associated with any one of the N measured MTRP measurement hypotheses.

[0111] There is an uplink transmission between the measurement times of multiple CMRs associated with any one of the N measured MTRP measurement hypotheses.

[0112] If at least one of the following occurs:

[0113] There is at least 1 uplink transmission symbol between the measurement times of multiple CMRs associated with any one of the N measured MTRP measurement hypotheses.

[0114] There is an uplink time slot between the measurement times of multiple CMRs associated with any one of the N measured MTRP measurement hypotheses.

[0115] There is an uplink transmission between the measurement times of multiple CMRs associated with any one of the N measured MTRP measurement hypotheses.

[0116] The processing method of the terminal includes at least one of the following:

[0117] The terminal ignores or discards the uplink transmission between the measurement times of multiple CMRs associated with the MTRP measurement hypothesis; wherein, the uplink transmission includes periodic or semi-persistent transmission or dynamically scheduled transmission.

[0118] The terminal calculates the priorities of the current CSI measurement and the uplink transmission according to predefined priority rules, selects the action with the higher priority to execute, and ignores or discards or does not update the action with the lower priority.

[0119] Wherein, the terminal ignoring or discarding the uplink transmission between the measurement times of multiple CMRs associated with the MTRP measurement hypothesis may be that the terminal does not transmit any signal or channel on the uplink transmission symbol between the measurement times of multiple CMRs associated with the MTRP measurement hypothesis; or the terminal does not transmit any signal or channel on the uplink transmission time slot between the measurement times of multiple CMRs associated with the MTRP measurement hypothesis, or other means.

[0120] See Figure 2 In an embodiment of the present application, a CSI measurement device 200 is provided. The device is applied to a terminal and includes:

[0121] An acquisition module 201, configured to acquire first CSI report configuration information from the network side, where the first CSI report configuration information is used to configure CMR and IMR.

[0122] A calculation module 202, configured to perform MTRP CSI calculation according to the first CSI report configuration information;

[0123] Wherein, the IMR is configured as a CSI-IM resource and / or an interference measurement NZP CSI-RS resource.

[0124] In some embodiments, before performing the MTRP CSI calculation, the apparatus further includes:

[0125] A determination module, configured to determine QCL information of the interference measurement NZP CSI-RS resource through high-layer signaling.
