Channel State Information (CSI) priority determination method, related equipment, and system

[0001] This application claims priority to the Chinese patent application with application number 2024101682196 filed with the State Intellectual Property Office of China on February 6, 2024, and priority to the Chinese patent application entitled “Channel State Information CSI Priority Determination Method, Related Equipment and System”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technology, and in particular to a CSI priority determination method, related equipment, and system. Background Art

[0003] R18 is the first version of the fifth generation (5G) mobile communication technology evolution stage. R18 Mobility introduces the concept of L1 / L2 Triggered Mobility (LTM), which instructs terminal devices to perform cell switching through L1 measurement reporting and L1 / L2 signaling. When a terminal device moves from the coverage area of ​​one cell to the coverage area of ​​another cell, the terminal device will perform a change in the serving cell. Compared with the traditional process of changing the serving cell based on L3 measurement and triggered by radio resource control (RRC) signaling, LTM can reduce service interruption time, that is, reduce the delay in the entire mobility process.

[0004] In the LTM process, L1 measurement reporting is also known as LTM channel state information (CSI) reporting. LTM CSI reporting involves the terminal device sending a CSI report (i.e., L1 measurement report) for LTM to the network device. Before performing LTM CSI reporting, the terminal device must determine the priority of the associated LTM CSI reports to determine the order in which LTM CSI reports are reported. Summary of the Invention

A terminal device can determine the priority associated with the CSI report for L1 / 2 triggered mobility LTM.

[0009] In conjunction with the first aspect, in some embodiments, the priority Pri LTM-CSI Determined based on the following formula: Pri LTM-CSI (y,k,c',s')=2·N cells '·M s '·y+N cells '·M s '·k+M s '·c'+s', priority Pri LTM-CSI The smaller the value of , the higher the priority of the CSI report association for LTM.

[0010] In combination with the first aspect, in some embodiments, the first candidate cell index c′ is used to indicate a candidate cell configured for CSI reporting of LTM.

[0011] In combination with the first aspect, in some embodiments, the first candidate cell index c' is equal to the minimum index of the candidate cells where the downlink reference signal associated with the CSI report for LTM is located, or the first candidate cell index c' is equal to the maximum index of the candidate cells where the downlink reference signal associated with the CSI report for LTM is located.

[0012] Without limitation thereto, the first candidate cell index c' may be equal to the index of any candidate cell where the downlink reference signal associated with the CSI report for LTM is located.

[0016] Without limitation thereto, if the CSI report for LTM is not configured with the first configuration parameter, the first candidate cell index c' may be equal to the index of any candidate cell where the downlink reference signal associated with the CSI report for LTM is located.

[0017] In combination with the first aspect, in some embodiments, the first candidate cell index c' is 0 or the index of the special cell SpCell; the priority Pri associated with the CSI report not used for LTM i-CSI Determined based on the following formula: Pri i-CSI (y,k,c,s)=2·N cells ·M s y+N cells ·M sk+M s c+s, where c = the index of the serving cell where the terminal device is located + 1, N cells is the maximum number of serving cells, s is the reporting configuration index of the CSI report not used for LTM, M s The number of report configurations for CSI reports not used for LTM.

[0018] Furthermore, the CSI report for LTM may overlap with the CSI report for non-LTM, for example, the CSI report for LTM and the CSI report for non-LTM are multiplexed on the same PUCCH. In this case, it is necessary to distinguish the priority of the CSI report association for LTM from the priority of the CSI report association for non-LTM. Optionally, the priority of the CSI report association for LTM can be made higher than the priority of the CSI report association for non-LTM. Specifically, the priority Pri of the CSI report association for LTM is re-determined. LTM-CSI The parameter c' in the calculation formula can be reset to 0 or the index of the special cell SpCell. Specifically, the priority Pri associated with the CSI report not used for LTM is reset. i-CSI The parameter c in the calculation formula can be re-determined to be the index value of the service cell where the terminal device is located + 1.

[0021] In conjunction with the first aspect, in some embodiments, the reporting configuration index s′ for CSI reporting used for LTM is smaller than the reporting configuration index s for CSI reporting not used for LTM.

[0022] In combination with the first aspect, in some embodiments, the report configuration index s' of the CSI report for LTM is less than the report configuration index s of the CSI report not for LTM, specifically including: re-determining the report configuration index s of the CSI report not for LTM, s after re-determination = maxNrofLTMCSI-ReportConfigurations + s before re-determination, maxNrofLTMCSI-ReportConfigurations is a high-level configuration parameter, and maxNrofLTMCSI-ReportConfigurations is used to indicate the maximum number of report configurations for the CSI report for LTM.

[0037] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0038] FIG1 illustrates a wireless communication system 100 involved in this application. The wireless communication system 100 can operate in high-frequency bands and is not limited to the Long Term Evolution (LTE) system. It can also be a fifth-generation mobile communication (5G) system, a new radio (NR) system, a machine-to-machine (M2M) system, or future communication systems such as the sixth-generation mobile communication system. As shown in FIG1 , the wireless communication system 100 may include one or more terminal devices 200, one or more network devices 300, and a core network (not shown).

[0039] The terminal device 200 may be distributed throughout the wireless communication system 100 and may be stationary or mobile. In some embodiments of the present application, the terminal device 200 may be a user equipment (UE), a mobile device, a mobile station, a mobile unit, an M2M terminal, a wireless unit, a remote unit, a terminal agent, a mobile client, and the like.

[0040] The network device 300 may be a base station, which may be used to communicate with one or more terminal devices, or may be used to communicate with one or more base stations having partial terminal functions (such as communication between a macro base station and a micro base station, such as an access point). The base station may be a base transceiver station (BTS) in a time division synchronous code division multiple access (TD-SCDMA) system, or an evolutionary Node B (eNB) in an LTE system, as well as a base station in a 5G system or a new air interface (NR) system. In addition, the base station may also be a transmission point (TRP), an access point (AP), a central unit (CU) or other network entity, and may include some or all of the functions of the above network entities.

[0041] In an embodiment of the present application, the terminal device 200 and the network device 300 can perform LTM operations in the wireless communication system 100. Exemplarily, the terminal device 200 can perform LTM CSI reporting (i.e., L1 measurement reporting). LTM CSI reporting means that the terminal device 200 sends a CSI report for LTM (i.e., L1 measurement report) to the network device 300. The CSI report for LTM can be used to indicate the channel status for LTM, so that the network device 300 decides whether to perform cell handover. Before LTM CSI reporting, the terminal device 200 can determine the priority associated with the CSI report for LTM to determine the order of LTM CSI reporting.

[0042] The network device 300 may receive a CSI report for LTM from the terminal device 200 and make a decision on whether to perform a cell handover based on the received CSI report for LTM. After determining to perform a cell handover, the network device 300 may send a cell handover signaling to the terminal device 200. The cell handover signaling may be used to trigger the terminal device 200 to switch from the currently residing cell (i.e., the serving cell, also referred to as the source cell) to another cell (i.e., the target cell), wherein the target cell is a cell selected from candidate cells adjacent to the serving cell where the terminal device 200 is located (e.g., the distance from the serving cell is less than 100 meters).

[0043] R18 is the first version of the 5G mobile communication technology evolution stage. The concept of L1 / L2 Triggered Mobility (LTM) is introduced in R18 Mobility. LTM refers to instructing the terminal device 200 to perform cell switching (i.e., change of serving cell) through L1 measurement reporting and L1 / L2 signaling. When the terminal device 200 moves from the coverage area of ​​one cell to the coverage area of ​​another cell, the terminal device 200 can perform a change of serving cell. Compared with the traditional process of changing the serving cell based on L3 measurement and triggered by radio resource control (RRC) signaling, LTM does not need to perform a complete L2 / L1 reset, thereby reducing service interruption time and reducing signaling overhead to achieve the goals of low latency, low overhead and low data interruption time.

[0044] The overall process of LTM provided by the embodiment of the present application is described below in conjunction with Figure 2.

[0045] Figure 2 shows the overall process of LTM provided by the embodiment of the present application.

[0046] S201. The terminal device 200 performs pre-configuration.

[0047] Specifically, the terminal device 200 can send a message 1 to the network device 300, which can be used to instruct the network device 300 to configure LTM, that is, to instruct the network device 300 to send the RRC configuration parameters of the candidate cell to the terminal device 200, so that the terminal device 200 can implement pre-configuration for the corresponding candidate cell. The candidate cell refers to multiple candidate cells for which the terminal device 200 can perform LTM operations.

[0048] In some embodiments, the network device 300 may send the RRC configuration parameters of the candidate cell to the terminal device 200 via a signaling message or the like.

[0049] Specifically, after receiving the RRC configuration parameters of the candidate cell, the terminal device 200 may implement pre-configuration for the corresponding candidate cell indicated by the RRC configuration parameters. Exemplarily, the RRC configuration parameters may include a reference signal configuration, and the terminal device 200 may perform beam measurement (i.e., L1 measurement) on the reference signal of the candidate cell indicated by the reference signal configuration based on the reference signal configuration. After completing the pre-configuration for the corresponding candidate cell, the terminal device 200 may store the configuration information of the corresponding candidate cell.

[0050] It should be noted that the above configuration information can be stored locally or in the cloud, and this embodiment of the present application does not limit this.

[0051] S202. The terminal device 200 synchronizes with the network device 300.

[0052] Specifically, the terminal device 200 and the network device 300 can perform downlink synchronization and uplink synchronization. Taking the downlink synchronization between the terminal device 200 and the network device 300 as an example, the network device 300 can send downlink synchronization information (including time synchronization information and frequency synchronization information) to the terminal device 200. After receiving the downlink synchronization information from the network device 300, the terminal device 200 can perform downlink synchronization with the network device 300 based on the downlink synchronization information. The downlink synchronization information may include a primary synchronization signal sequence, a secondary synchronization signal sequence, and a reference signal sequence issued by the network device 300. The embodiment of the present application does not limit the content of the downlink synchronization information.

[0053] S203 . The terminal device 200 sends an L1 measurement report (CSI report for LTM) to the network device 300 .

[0054] In an embodiment of the present application, the L1 measurement report can be used to indicate the channel state for LTM so that the network device 300 decides whether to perform cell switching. The L1 measurement report can also be referred to as a beam measurement result, and can also be referred to as a CSI report for LTM. Among them, the CSI report for LTM includes but is not limited to the L1-RSRP, L1-SINR and other custom information of the candidate cell. Among them, L1-RSRP is the reference signal receiving power (RSRP) transmitted by the beam of the corresponding candidate cell, and L1-SINR is the signal to interference plus noise ratio (SINR) of the reference signal transmitted by the beam of the corresponding candidate cell on the terminal device side.

[0055] It should be noted that the terminal device 200 sending the L1 measurement report to the network device 300 can be called the terminal device 200 performing L1 measurement reporting, and can also be called the terminal device 200 performing LTM CSI reporting.

[0056] In an embodiment of the present application, before LTM CSI reporting, the terminal device 200 may determine the priority of the CSI report association for LTM to determine the order of LTM CSI reporting.

[0057] S204. The network device 300 makes an LTM decision.

[0058] Specifically, after receiving the L1 measurement report (CSI report for LTM) from the terminal device 200, the network device 300 can decide whether to perform cell switching based on the L1 measurement report (CSI report for LTM). For example, when the L1 measurement result (such as RSRP) of a candidate cell is better than that of the current serving cell, or when the L1 measurement result (such as RSRP) of a candidate cell is greater than a certain threshold, the network device 300 can determine to perform cell switching.

[0059] In the embodiment of the present application, cell handover may refer to handing over the terminal device 200 from the cell in which it is currently residing (i.e., the serving cell, also referred to as the source cell) to another cell (i.e., the target cell). The target cell is a cell selected from candidate cells that are adjacent to the serving cell where the terminal device 200 is located (e.g., the distance from the serving cell is less than 100 meters).

[0060] S205 . The network device 300 sends a cell switching signaling to the terminal device 200 .

[0061] Specifically, after determining to perform cell switching, the network device 300 may send a cell switching signaling to the terminal device 200 , where the cell switching signaling may be used to trigger the terminal device 200 to switch from a source cell to a target cell.

[0062] S206. The terminal device 200 accesses the target cell.

[0063] Specifically, after receiving the cell switching signaling from the network device 300, the terminal device 200 may switch the source cell to the target cell in response to the cell switching signaling.

[0064] As described above, in the embodiment of the present application, before LTM CSI is reported, the terminal device 200 may determine the priority of the CSI report association for LTM to determine the order of LTM CSI reporting. The method for determining the priority of the CSI report association for LTM can refer to the method for determining the priority of the CSI report association. The method for determining the priority of the CSI report association is described below:

[0065] The priority of the CSI report association can be determined based on the following formula: i-CSI (y, k, c, s) = 2·N cells ·M s y+N cells ·M s k+M s ·c+s. i-CSIThe smaller the value, the higher the priority of the CSI report association. Among them, the parameter y is the type of CSI report, and there are the following cases: when the physical uplink shared channel (PUSCH) carries a non-periodic CSI report, y=0; when the PUSCH carries a semi-continuous CSI report, y=1; when the physical uplink control channel (PUCCH) carries a semi-continuous CSI report, y=2; when the PUCCH carries a periodic CSI report, y=3. Parameter k is an indication value of whether the CSI report carries RSRP or SINR. When the CSI report carries RSRP or SINR, k=0; when the CSI report does not carry RSRP or SINR, k=1. Parameter c is the index of the service cell where the terminal device 200 is located. Parameter N cells Refers to the maximum number of serving cells, the parameter N cells It is configured through high-level signaling, such as N cells The parameter M may be equal to the value of the high-level configuration parameter maxNrofServingCells, which may be used to indicate the maximum number of serving cells. The parameter s refers to the report configuration index of the CSI report, which may be used to identify the parameter set of the report configuration in the CSI report sent by the terminal device 200. s Refers to the number of report configurations for CSI reports. The parameter M s It is configured through high-level signaling, such as M s It may be equal to the value of the higher-layer configuration parameter maxNrofCSI-ReportConfigurations, which may be used to indicate the maximum number of report configurations for CSI reports.

[0066] It should be noted that the value of parameter c is unique. The measurement resource set (CSI-SSB-ResourceSet) of the CSI report contains a set of resource blocks, each of which contains a synchronization signal block (SSB) and a corresponding downlink reference signal. The downlink reference signal of each resource block is transmitted by the serving cell where the terminal device 200 is located. The value of parameter c is the index of the serving cell where the downlink reference signal associated with the CSI report is located.

[0067] In order to consider whether the method for determining the priority of CSI report association is applicable to determining the priority of CSI report association for LTM, the basic framework of LTM CSI reporting is briefly introduced below.

[0068] The basic framework of LTM CSI reporting may include the reporting configuration of LTM CSI reporting and the resource configuration of LTM CSI reporting. The reporting configuration of each LTM CSI reporting is associated with the resource configuration of LTM CSI reporting for channel measurement. In addition, the reporting configuration of each LTM CSI reporting may include parameters of time domain behavior, the number of candidate cells, and the number of reference signals for each candidate cell. Among them, the parameters of time domain behavior may indicate the type of CSI report used for LTM, such as non-periodic CSI reports for LTM carried on PUSCH, semi-persistent CSI reports for LTM carried on PUSCH, semi-persistent CSI reports for LTM carried on PUCCH, and periodic CSI reports for LTM carried on PUCCH. In addition, if the CSI report for LTM is configured with a first configuration parameter, such as the spCellInclusion parameter, the CSI report for LTM may include L1 measurement results associated with special cells (SpCells).

[0069] Figure 3 shows the composition of the measurement resource set for LTM CSI reporting. The measurement resource set for LTM CSI reporting (LTM-CSI-SSB-ResourceSet) contains a resource list (LTM-CSI-SSB-ResourceList) and a candidate cell list. Each resource block in the resource list contains a synchronization signal block and a corresponding downlink reference signal. The downlink reference signal of each resource block comes from a different candidate cell. As shown in Figure 3, the downlink reference signal of resource block 1 comes from candidate cell 1, the downlink reference signal of resource block 2 comes from candidate cell 2, and the downlink reference signal of resource block 3 comes from candidate cell 3.

[0070] In the embodiment of the present application, the terminal device 200 can perform L1 measurement on downlink reference signals from different candidate cells and send corresponding L1 measurement reports to the network device 300. Since the candidate cells from which the downlink reference signals come are not unique, if the calculation formula for the priority of CSI report association is used to determine the priority of CSI report association for LTM, the value of parameter c is not unique.

[0071] Therefore, the embodiment of the present application provides a CSI priority determination method, the terminal device 200 can determine the priority associated with the CSI report for LTM, and the priority can be determined by the following parameters: the type y of the CSI report for LTM, the indicator value k of whether the CSI report for LTM carries RSRP or SINR, the first candidate cell index c', the number of candidate cells N cells', report configuration index s' for LTM CSI report, number of report configurations M for LTM CSI report s ', where the first candidate cell index c' is different from the index of the serving cell where the terminal device 200 is located.

[0072] Priority Pri of CSI report association for LTM LTM-CSI It can be determined based on the following formula: Pri LTM-CSI (y,k,c',s')=2·N cells '·M s '·y+N cells '·M s '·k+M s '·c'+s'. The priority Pri LTM-CSI The smaller the value, the higher the priority of the CSI report associated with LTM. The value of parameter y is taken in the same way as the value of parameter y in the priority calculation formula associated with CSI report: when PUSCH carries non-periodic CSI report for LTM, y=0; when PUSCH carries semi-persistent CSI report for LTM, y=1; when PUCCH carries semi-persistent CSI report for LTM, y=2; when PUCCH carries periodic CSI report for LTM, y=3. The value of parameter k is taken in the same way as the value of parameter k in the priority calculation formula associated with CSI report: when the CSI report for LTM carries RSRP or SINR, k=0; when the CSI report for LTM does not carry RSRP or SINR, k=1. The parameter c' can be used to indicate the candidate cell for configuring the CSI report for LTM, the parameter s' can be used to identify the parameter set of the report configuration for the CSI report for LTM sent by the terminal device 200, and the parameter M s ' is the maximum number of reporting configurations for CSI reporting for LTM.

[0073] (1) Example 1

[0074] In some embodiments, the parameter N cells The value of ' is related to the parameter N in the priority calculation formula associated with the CSI report cells The value of the parameter N is the same as cells ' is configured through high-level signaling, such as N cells ' can be equal to the value of the high-level configuration parameter maxNrofServingCells. The value of parameter s' is determined in the same way as the value of parameter s in the priority calculation formula associated with the CSI report. Parameter M s The value of ' is related to the parameter M in the priority calculation formula associated with the CSI report sThe value of parameter M is the same as s ' is configured through high-level signaling, such as M s ' can be equal to the value of the higher-layer configuration parameter maxNrofLTMCSI-ReportConfigurations, which can be used to indicate the maximum number of reporting configurations for LTM CSI reporting. The reporting configuration for LTM CSI reporting has the same basic configuration information as the reporting configuration for CSI reporting, except for the names of the corresponding parameters. For example, the ltm-CSI-ReportConfigId-r18 parameter in the reporting configuration for LTM CSI reporting corresponds to the reportConfigId parameter in the reporting configuration for CSI reporting.

[0075] In some embodiments, after determining the parameters y, k, and N cells ', parameter s', parameter M s In the case of ', parameter c' may be the index of any candidate cell where the downlink reference signal associated with the CSI report for LTM is located.

As shown in FIG3 , parameter c' may take the minimum candidate cell index value of 1. Parameter c' may also be the maximum index of the candidate cells where the downlink reference signal associated with the CSI report for LTM is located. As shown in FIG3 , parameter c' may take the maximum candidate cell index value of n.

[0076] Multi-RAT Dual Connectivity (MR-DC) allows a UE with multiple Rx / Tx configurations to utilize radio resources scheduled by two base stations in the RRC_CONNECTED state. One base station acts as a master node (MN), which provides control plane connectivity to the core network; the other acts as a secondary node (SN), which provides additional radio resources to the UE.

[0077] In the embodiment of the present application, in the MR-DC scenario, a Master Cell Group (MCG) is a group of candidate cells associated with a mobile node (MN). The MCG may include a primary cell and optionally one or more secondary cells. In the MR-DC scenario, a Secondary Cell Group (SCG) is a group of candidate cells associated with a network node (SN). The SCG may include a special cell (SpCell) and optionally one or more secondary cells.

[0078] In an embodiment of the present application, in the MR-DC scenario, by configuring multiple SCGs for the terminal device 200, the terminal device 200 can perform continuous SCG changes according to the instructions of the network device 300 or pre-configured decision conditions. Since no reconfiguration is required, the signaling overhead and the interruption time of the SCG change can be reduced.

[0079] In some embodiments, after determining the parameters y, k, and N cells ', parameter s', parameter M s In the case of ', the parameter c' may be a fixed value. For example, the parameter c' within the candidate primary cell group may be 0; or the parameter c' within the candidate secondary cell group may be the index of a special cell (SpCell).

[0080] In some embodiments, after determining the parameters y, k, and N cells ', parameter s', parameter M s ', the parameter c' may be related to whether the CSI report for LTM is configured with a first configuration parameter (such as the spCellInclusion parameter), and the first configuration parameter may be used to indicate whether the terminal device 200 includes a CSI report for LTM associated with the current special cell (SpCell), and the first configuration parameter can be configured only when the current special cell (SpCell) is configured as a candidate cell for the CSI report for LTM. Specifically, if the CSI report for LTM is configured with a first configuration parameter, such as the spCellInclusion parameter, the parameter c' within the candidate primary cell group may be 0; or, the parameter c' within the candidate secondary cell group may be the index of the special cell (SpCell). If the CSI report for LTM is not configured with a first configuration parameter, such as the spCellInclusion parameter, the parameter c' may be the index of any candidate cell where the downlink reference signal associated with the CSI report for LTM is located. Exemplarily, the parameter c' may be the minimum index of the candidate cell where the downlink reference signal associated with the CSI report for LTM is located. As shown in FIG3 , the parameter c' may take the minimum candidate cell index value of 1. The parameter c' may also be the maximum index of the candidate cells where the downlink reference signal associated with the CSI report for LTM is located. As shown in FIG3 , the parameter c' may take the maximum candidate cell index value n.

[0081] (II) Example 2

[0082] Furthermore, the CSI report for LTM and the CSI report not for LTM may overlap, for example, the CSI report for LTM and the CSI report not for LTM are multiplexed on the same PUCCH. In this case, the method for determining the priority of the CSI report associated with LTM and the method for determining the priority of the CSI report associated with non-LTM are not unified, and the priorities of the CSI report for LTM and the CSI report not for LTM can only be determined separately in a single scenario (for example, a scenario in which only CSI reports for LTM exist or a scenario in which only CSI reports not for LTM exist). Therefore, it is necessary to unify the method for determining the priority of the CSI report associated with LTM and the priority of the CSI report associated with non-LTM, and distinguish the priority of the CSI report associated with LTM from the priority of the CSI report associated with non-LTM. Optionally, the priority of the CSI report associated with LTM can be made higher than the priority of the CSI report associated with non-LTM.

Among them, the previous parameter N is re-determined cells ' is configured through high-level signaling, such as re-determining the previous N cells 'Can be equal to the value of the high-level configuration parameter maxNrofServingCells.

[0087] Specifically, the parameter N is re-determined cells , re-determine the parameter N cells You can redefine the previous parameter N cellsThe value of +1. Among them, the previous parameter N is re-determined cells It is configured through high-level signaling, such as re-determining the previous N cells It can be equal to the value of the high-level configuration parameter maxNrofServingCells.

[0088] For example, the terminal device 200 is configured with 4 candidate cells, and the index values ​​of these 4 candidate cells are 0, 1, 2, and 3 from small to large. When calculating the priority of the CSI report association for LTM, the parameter c' is 0. When calculating the priority of the CSI report association not used for LTM: if the index value of the serving cell is 0, the parameter c is 1; if the index value of the serving cell is 1, the parameter c is 2; if the index value of the serving cell is 2, the parameter c is 3; if the index value of the serving cell is 3, the parameter c is 4. Because the parameter c can be 4 when calculating the priority of the CSI report association not used for LTM, the previous parameter N is re-determined. cells ' is 4, then re-determine the subsequent parameter N cells 'Should be 5.

[0089] In other embodiments, the parameters s and M can be re-determined. s ' and parameter M s To unify the method for determining the priority of CSI report associations for LTM and the priority of CSI report associations not used for LTM, and distinguish the priority of CSI report associations for LTM and the priority of CSI report associations not used for LTM.

[0090] Specifically, the parameter s is re-determined. The parameter s after re-determination can be the value of the parameter s before re-determination + the parameter M before re-determination. s ' value, so that the parameter s' is less than the parameter s. Among them, the previous parameter M is re-determined s 'It can be configured through high-level signaling, such as re-determining the previous M s ' may be equal to the value of the higher-layer configuration parameter maxNrofLTMCSI-ReportConfigurations, which may be used to indicate the maximum number of reporting configurations for CSI reporting for LTM.

[0091] Specifically, the parameter M is re-determined s ', re-determine the parameter M s 'Can be used to re-determine the previous parameter M s 'value + redetermine the previous parameter M s The value of . Among them, the previous parameter M is re-determined s'It can be configured through high-level signaling, such as re-determining the previous M s ' can be equal to the value of the high-level configuration parameter maxNrofLTMCSI-ReportConfigurations. Re-determine the previous parameter M s It can be configured through high-level signaling, such as re-determining the previous M s It can be equal to the value of the higher-level configuration parameter maxNrofCSI-ReportConfigurations.

[0092] Specifically, the parameter M is re-determined s , re-determine the parameter M s You can redefine the previous parameter M s 'value + redetermine the previous parameter M s The value of . Among them, the previous parameter M is re-determined s 'It can be configured through high-level signaling, such as re-determining the previous M s ' can be equal to the value of the high-level configuration parameter maxNrofLTMCSI-ReportConfigurations. Re-determine the previous parameter M s It can be configured through high-level signaling, such as re-determining the previous M s It can be equal to the value of the higher-level configuration parameter maxNrofCSI-ReportConfigurations.

[0093] For example, the number of report configurations for CSI reports for LTM is 2, and the report configuration indexes for CSI reports for LTM are 0 and 1 respectively. The number of report configurations for CSI reports not for LTM is 3, and the report configuration indexes for CSI reports not for LTM are 0, 1, and 2 respectively. When calculating the priority of CSI report associations for LTM, the parameter s' can be 0 or 1, and the parameter M s ' is 5. When calculating the priority of the CSI report association not used for LTM, the parameter s can be 2 / 3 / 4, and the parameter M s is 5.
