AI Technical Summary
In new air communication, high-frequency channels attenuate rapidly, causing terminals to be unable to obtain the CSI of candidate cells in a timely manner when switching to candidate cells, which affects communication quality and coverage.
The terminal determines the overall processing unit for multiple CSI reports within the same time unit, and updates low-priority CSI reports according to priority. The network device sends information to instruct the CSI processing unit to ensure the timely acquisition of high-priority CSI reports.
By prioritizing CSI reports, resource conflicts are avoided, ensuring that terminals quickly switch to candidate cells, improving communication quality and coverage, and reducing data transmission latency.

[0196] FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG. 1, the communication system can include a terminal 101 and a network device 102.

[0200] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers are controlled by the CU, and the rest or all of the protocol layers are distributed in the DU and controlled by the CU. However, the present disclosure is not limited thereto.
[0201] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed by the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.
[0202] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than FIG. 1. The number and form of each subject is arbitrary, and the connection relationship between each subject is exemplary. Each subject can be connected or not connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.
[0203] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), 6th generation mobile communication system (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).
[0204] In NR, especially when the communication frequency band is in frequency range 2 (above 6 GHz), due to the rapid attenuation of high-frequency channels, in order to ensure coverage, beam-based transmission and reception need to be used. Currently, in order to consider fast switching, Rel-18 studies L1 / L2 trigger mobility (LTM), that is, the base station configures multiple candidate cells for the terminal, each candidate cell is configured with some Synchronization Signal Block (SSB), and the terminal can measure the SSB of the candidate cell and report the measurement result of the SSB corresponding to the M candidate cells, wherein the measurement result of N SSBs on each candidate cell is reported, such as Layer 1 Reference Signal Received Power (L1-RSRP).
[0205] Based on this measurement result, the base station configures a target cell for the terminal, and a Transport configuration indicator (TCI) state identifier (ID) corresponding to the target cell. The reference signal resource (RS) indicated in the TCI(state) identifier (ID) can be the SSB of the target cell, or the Tracking Reference Signal (TRS) having a quasi co-location (QCL) relationship with the SSB of the target cell.
[0206] If the terminal switches to the target cell, the target cell becomes a new serving cell. Further, the terminal needs to first obtain the configuration information of the reference signal resource (RS) for CSI (channel state information) measurement and CSI reporting of the new serving cell, then perform CSI measurement on the new serving cell, and then report the CSI to the new serving cell. The new serving cell schedules the terminal based on the obtained CSI and transmits data. However, this will cause a large data transmission delay. If the new serving cell does not obtain the CSI of the terminal, it directly schedules the terminal based on the default CSI. If the default CSI is poor, the transmission rate of the terminal is low, and if the default CSI is high, the decoding success rate will be low, so the transmission rate is still low.
[0207] To solve the above problems, it is proposed that the terminal can obtain the CSI of the candidate cell in advance, and how to process multiple CSI reports including the CSI of the candidate cell in the case of simultaneous calculation becomes a problem to be solved. The method proposed by the present disclosure can not update the CSI report with low priority in the case that the CSI processing units occupied by multiple CSI reports are greater than the CSI processing units supported by the terminal, so as to solve the resource conflict problem of the CSI processing unit.
[0208] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises:
[0209] In step S2101, the network device sends first information to the terminal.
[0210] In some embodiments, the first information can be used to determine multiple CSI reports that the terminal needs to process in the same time unit.
[0211] Optionally, the multiple CSI reports that need to be processed can be understood as multiple CSI reports that need to be calculated or need to be updated.
[0212] In some embodiments, the first information can be used to indicate multiple CSI reports that the terminal needs to process in the same time unit.
[0213] In some embodiments, the network device can send the first information through downlink control information (DCI) signaling. Optionally, the terminal receives the DCI signaling to obtain the first information.
[0214] In some embodiments, the network device can send the first information through radio resource control (RRC) signaling. Optionally, the terminal receives the RRC signaling to obtain the first information.
[0215] In some embodiments, the network device can send the first information through medium access control control element (MAC CE) signaling. Optionally, the terminal receives the MAC CE signaling to obtain the first information.
[0216] In some embodiments, the first information includes CSI report configuration related information.
[0217] In some embodiments, the first information can comprise identifications of cells corresponding to the plurality of CSI reports respectively. The terminal determines the plurality of CSI reports based on the identifications of the cells. For example, one or more non-serving cells correspond to one CSI report, and the serving cell corresponds to one CSI report. For another example, the first information can comprise a plurality of sets of cell identifications, and different sets correspond to one CSI report.
[0218] In some embodiments, the first information can comprise reporting quantities corresponding to the plurality of CSI reports respectively. The terminal determines the plurality of CSI reports based on the reporting quantities. For example, the reporting quantities comprise L1-RSRP or L1-SINR corresponding to one CSI report, and the reporting quantities comprise PMI, RI, CQI, etc. corresponding to another CSI report.
[0219] In some embodiments, the first information can comprise type identifications corresponding to the plurality of CSI reports. The terminal determines the plurality of CSI reports based on the type identifications. For example, one CSI report corresponds to a type identification of ‘typeI-SinglePanel’, and another CSI report corresponds to a type identification of ‘typeII’. In some embodiments, the first information can comprise indication information of the plurality of CSI reports. For example, the indication information comprises ‘0’ and ‘1’, wherein ‘0’ can indicate CSI measurement on the serving cell of the terminal, and ‘1’ can indicate CSI measurement on the non-serving cell of the terminal.
[0220] At step S2102, the terminal determines, according to the first information, the plurality of CSI reports that need to be processed in the same time unit.
[0221] In some embodiments, the time unit can comprise, but is not limited to, a subframe, a slot, a symbol, etc.
[0222] In some embodiments, the plurality of CSI reports can comprise a first CSI report, a second CSI report, a third CSI report, etc., which need to be calculated in the same time period, for example, in the same symbol.
[0223] In some embodiments, the terminal can determine, according to the identifications of the cells corresponding to the plurality of CSI reports comprised in the first information, the plurality of CSI reports that need to be processed in the same time unit.
[0224] In some embodiments, the terminal can determine, according to the type identifications corresponding to the plurality of CSI reports comprised in the first information, the plurality of CSI reports that need to be processed in the same time unit.
[0225] In some embodiments, the terminal can determine, according to the reporting quantity corresponding to the plurality of CSI reports included in the first information, the plurality of CSI reports that need to be processed in the same time unit.
[0226] In step S2103, the network device sends second information to the terminal, and the second information is used to determine the reference signal resource for CSI measurement corresponding to each CSI report.
[0227] In some embodiments, the second information can include the reference signal resource for CSI measurement of each CSI report in the plurality of CSI reports corresponding to the cell. The terminal can perform CSI measurement on the cell based on the reference signal resource for CSI measurement of the cell.
[0228] In some embodiments, the second information can be CSI measurement configuration information sent by the network device, and based on the CSI measurement configuration information, the reference signal resource of each CSI report that needs to be measured can be determined.
[0229] In some embodiments, the CSI measurement configuration can include at least one of the following information:
[0230] The configuration information of the CSI-RS resource, for example, can include resource periodicity: the CSI-RS resource can be periodic, semi-persistent or aperiodic. The type of measurement resource, wherein the type of measurement resource can include resources for channel measurement and resources for interference measurement.
[0231] The configuration information of CSI reporting, for example, can include reporting type, reporting content, reporting frequency and reporting occasion, etc. Wherein, the reporting type can be periodic, semi-persistent (based on PUCCH or PUSCH) or aperiodic. The reporting content is the reported parameter, for example, can include the precoding matrix identifier (PMI), the rank identifier (RI), the layer identifier (LI), the channel quality identifier (CQI), etc.
[0232] The codebook information of CSI reporting, for example, can include codebook type and codebook limited subset, etc. Wherein, the codebook type is used to specify the codebook type used when reporting, such as Type I, Type II or enhanced Type II codebook. The codebook limited subset is used to limit the range of precoding matrixes reported by the terminal.
[0233] Configure the power control parameter in the CSI measurement and reporting process;
[0234] configuring the restriction on the CSI measurement and reporting in the time domain and the frequency domain, etc.
[0235] At step S2104, the terminal determines the third CSI processing unit corresponding to each of the plurality of CSI reports, and determines the total first CSI processing unit occupied by the plurality of CSI reports according to the third CSI processing units.
[0236] In some embodiments, the third channel state information processing unit (CSI Processing Unit, CPU) corresponding to each of the CSI reports includes a third CSI processing unit required for calculating or updating each of the CSI reports.
[0237] In some embodiments, the third CSI processing unit is determined based on at least one of the following:
[0238] The number of cells corresponding to each of the CSI reports;
[0239] The number of channel state information reference signal (CSI-RS) resources used for CSI measurement by each of the cells corresponding to each of the CSI reports;
[0240] The number of ports of the CSI-RS resource corresponding to each of the CSI reports;
[0241] The number of channel measurement resources used for CSI measurement by each of the cells corresponding to each of the CSI reports;
[0242] The type of each of the CSI reports;
[0243] The reporting amount corresponding to each of the CSI reports.
[0244] In some embodiments, the number of cells corresponding to each of the CSI reports is positively correlated with the size of the CSI processing unit, that is, the more the number of cells corresponding to each of the CSI reports, the larger the CSI processing unit required by the CSI report.
[0245] In some embodiments, the number of CSI-RS resources used for CSI measurement corresponding to each of the CSI reports is positively correlated with the size of the CSI processing unit, that is, the more the number of CSI-RS resources used for CSI measurement corresponding to each of the CSI reports, the larger the CSI processing unit required by the CSI report.
[0246] Optionally, the CSI-RS resources corresponding to one CSI report for CSI measurement can correspond to one cell or different cells, in which case the CSI processing units required by the CSI report can only be related to the number of CSI-RS resources for CSI measurement, without further considering the number of cells. Another CSI report corresponds to N cells, and the CSI-RS resources for CSI measurement corresponding to each of the N cells correspond to the respective cells one by one, for example, the number of CSI-RS resources corresponding to each cell for CSI measurement is M, then the CSI processing units required by the CSI report are related to both the number N of corresponding cells and the number M of CSI-RS resources corresponding to each cell, for example, the CSI processing units required by the CSI report are proportional to the number N of corresponding cells and the number M of CSI-RS resources corresponding to each cell.
[0247] In some embodiments, the number of ports of the CSI-RS resources corresponding to each CSI report is positively correlated with the size of the CSI processing units, that is, the more the number of ports of the CSI-RS resources corresponding to the CSI report, the larger the CSI processing units required by the CSI report. For example, the size of the CSI processing units required by the CSI-RS resources with a port number of 4 is larger than the size of the CSI processing units required by the CSI-RS resources with a port number less than 4.
[0248] In some embodiments, the number of channel measurement resources for CSI measurement corresponding to each CSI report is positively correlated with the size of the CSI processing units, that is, the more the number of channel measurement resources for CSI measurement corresponding to the CSI report, the larger the CSI processing units required by the CSI report.
[0249] Optionally, the channel measurement resources corresponding to one CSI report for CSI measurement can correspond to one cell or different cells, in which case the CSI processing units required by the CSI report can only be related to the number of channel measurement resources for CSI measurement, without further considering the number of cells. Another CSI report corresponds to N cells, and the channel measurement resources for CSI measurement corresponding to each of the N cells correspond to the respective cells one by one, for example, the number of channel measurement resources corresponding to each cell for CSI measurement is M, then the CSI processing units required by the CSI report are related to both the number N of corresponding cells and the number M of channel measurement resources corresponding to each cell, for example, the CSI processing units required by the CSI report are proportional to the number N of corresponding cells and the number M of channel measurement resources corresponding to each cell.
[0250] In some embodiments, the sizes of the CSI processing units required by different types of CSI are different.
[0251] In some embodiments, the reporting quantity corresponding to each CSI report is related to the size of the CSI processing unit. The more the reporting quantity corresponding to each CSI report, the larger the size of the CSI processing unit required by the CSI; the less the reporting quantity corresponding to each CSI report, the smaller the size of the CSI processing unit required by the CSI. The combination of the reporting quantity corresponding to each CSI report also affects the size of the CSI processing unit, and different combinations of reporting quantities correspond to different sizes of occupied CSI processing units. The calculation amount of the reporting quantity corresponding to each CSI report also affects the size of the CSI processing unit. The larger the calculation amount of the reporting quantity corresponding to each CSI report, the larger the size of the CSI processing unit required by the CSI; the smaller the calculation amount of the reporting quantity corresponding to each CSI report, the smaller the size of the CSI processing unit required by the CSI.
[0252] In some embodiments, the terminal can perform CSI processing unit calculation on each CSI report in the plurality of CSI reports to determine the third CSI processing unit occupied by each CSI report. Optionally, the plurality of CSI reports includes a first CSI report and a second CSI report. Optionally, the first CSI report is a CSI report of at least one first cell, and the second CSI report is a CSI report of at least one second cell, wherein the first cell is a non-serving cell of the terminal, and the second cell is one of a serving cell and a non-serving cell of the terminal.
[0253] In some embodiments, the first cell is not currently a serving cell of the terminal, that is, the first cell is currently a non-serving cell of the terminal. It can be understood that the first cell is not currently a serving cell of the terminal, that is, when the terminal determines the reference signal resource of the first cell, the first cell is not yet a serving cell of the terminal.
[0254] In some embodiments, the first cell can be one of a candidate cell, a neighbor cell, and a target cell of the terminal. It can be understood that when the terminal determines the first reference signal resource, the first cell is not yet a serving cell of the terminal. For example, the first cell can be a cell to which the terminal is about to switch to, and after the terminal switches to the first cell, the first cell becomes a serving cell of the terminal.
[0255] In some embodiments, the second CSI report can be a CSI report of the serving cell or can not be a CSI report of the serving cell, for example, the second CSI report can be a measurement report of L1-Reference Signal Received Power (RSRP) or L1-Signal-to-Noise-and-Interference Ratio (SNIR) of a non-serving cell.
[0256] In the following, taking the third CSI processing unit occupied by the first CSI report as an example, the determination of the third CSI processing unit occupied by each of the plurality of CSI reports is explained:
[0257] In some embodiments, the third CSI processing unit occupied by the first CSI report is related to at least one of the following:
[0258] The number of first cells corresponding to the first CSI report;
[0259] The number of CSI-RS resources corresponding to the first CSI report for CSI measurement;
[0260] The number of ports of the CSI-RS resource corresponding to the first CSI report;
[0261] The number of channel measurement resources corresponding to the first CSI report for CSI measurement;
[0262] The type of the first CSI report;
[0263] The reporting quantity of the first CSI report.
[0264] In some embodiments, the type of the first CSI report can include, but is not limited to, the following types set in the codebook: single panel type I (typeI-SinglePanel), multi-panel type II (typeI-multiPanel), port selection type II (typeII-PortSelection), type II (typeII), enhanced port selection type II (enhanced typeII-PortSelection), and enhanced type II (typeII).
[0265] In some embodiments, the type of the CSI of the first CSI report can be single CSI with wideband frequency-granularity.
[0266] In some embodiments, the reporting quantity of the first CSI report can be any of the following:
[0267] ‘CSI-RS Resource Indicator (CRI) - Rank Indicator (RI) - Precoding Matrix Indicator (PMI) - Channel Quality Indicator (CQI)’, ‘CRI - RI - Layer Indicator (LI)’, ‘CRI - RI - LI - PMI - CQI’.
[0268] In some embodiments, the first CSI report occupies the third CSI processing unit differently from the second CSI report. For example, the first CSI report occupies the third CSI processing unit with a reporting quantity of ‘CRI - RI - PMI - CQI’, ‘CRI - RI - LI’, ‘CRI - RI - LI - PMI - CQI’, which is different from the third CSI processing unit occupied by the second CSI report with a reporting quantity of ‘CRI-RSRP’, ‘CRI-SNIR’, ‘SSB-Index-RSRP’, ‘SSB-Index-SINR’, ‘CRI-RSRP-Index’, ‘SSB-Index-RSRP-Index’, ‘CRI-SINR-Index’, ‘SSB-Index-SINR-Index’.
[0269] In some embodiments, the determination process of the third CSI processing unit occupied by the first CSI report can include:
[0270] determining the number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement corresponding to the first CSI report, the number of ports of the CSI-RS resources corresponding to the first CSI report, the number of channel measurement resources for CSI measurement corresponding to the first CSI report, the type of the first CSI report, and the reporting quantity corresponding to the first CSI report, determining the third CSI processing unit occupied by the first CSI report based on at least one of the above information.
[0271] In some embodiments, the number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement, the number of ports of the CSI-RS resources, the number of channel measurement resources for CSI measurement, the type of the first CSI report, and the reporting quantity corresponding to the first CSI report can be determined based on the CSI measurement configuration corresponding to the first CSI report of the network device.
[0272] In some embodiments, after determining the third CSI processing units occupied by each of the plurality of CSI reports, the third CSI processing units occupied by each of the plurality of CSI reports can be summed up to obtain the total CSI processing units occupied by the plurality of CSI reports, which is referred to as the first CSI processing units in the embodiments of the present disclosure.
[0273] In some embodiments, the total first CSI processing units occupied by the plurality of CSI reports can be determined based on the number of the plurality of CSI reports. Alternatively, a limit of the CSI processing units occupied by each of the CSI reports can be pre-configured or agreed, and further, the first CSI processing units occupied by the plurality of CSI reports can be determined based on the number of the CSI reports and the limit of the CSI processing units occupied by each of the CSI reports.
[0274] In some embodiments, based on the CSI measurement configuration information of the plurality of CSI reports, the total occupied resources can be determined, and the total first CSI processing units occupied by the plurality of CSI reports can be determined according to the total occupied resources.
[0275] In some embodiments, based on the types of the plurality of CSI reports and the quota (such as size) of the CSI processing units of each type, the number of the CSI reports under each type can be obtained by counting each type, and further, the total first CSI processing units occupied by the plurality of CSI reports can be determined based on the number of the CSI reports under each type and the quota of the CSI processing units of the type. The quota of the CSI processing units of each type can be configured by the network or agreed by the protocol.
[0276] In step S2105, in response to the first CSI processing units being greater than the second CSI processing units supported by the terminal, the priority of each of the plurality of CSI reports is determined.
[0277] In some embodiments, the second CSI processing units supported by the terminal can be determined based on the protocol agreement, the network configuration, or the capability of the terminal.
[0278] In some embodiments, if the first CSI processing units occupied by the plurality of CSI reports in the same time unit are greater than the second CSI processing units supported by the terminal, that is, the first CSI processing units required by the terminal exceed the second CSI processing units that can be provided by the terminal itself, the terminal can determine the priority of each of the plurality of CSI reports.
[0279] In some embodiments, the priority of each of the plurality of CSI reports is determined based on the bearing mode indication parameter y of each of the CSI reports, the indication parameter k of whether to carry the first reporting quantity, the corresponding cell index c, and the service cell limit N of the terminal. cellsat least one of the CSI report configuration identification s and the maximum number M of CSI report configurations of the terminal s determines the priority of each CSI report.
[0280] In some embodiments, the priority of each CSI report can be determined as follows:
[0281] Pri iCSI (y, k, c, s) = 2 · N cells · M s · y + N cells · M s · k + M s · c + s (1)
[0282] where y = 0 indicates aperiodic CSI reports on PUSCH (y = 0 for aperiodic CSI reports to be carried on PUSCH);
[0283] y = 1 indicates semi-persistent CSI reports on PUSCH (y = 1 for semi-persistent CSI reports to be carried on PUSCH);
[0284] y = 2 indicates semi-persistent CSI reports on PUCCH (y = 2 for semi-persistent CSI reports to be carried on PUCCH);
[0285] y = 3 indicates periodic CSI reports on PUCCH (y = 3 for periodic CSI reports to be carried on PUCCH).
[0286] k = 0 indicates CSI reports carrying L1-RSRP or L1-SINR (k = 0 for CSI reports carrying L1-RSRP or L1-SINR); wherein the following reporting quantities will carry L1-RSRP or L1-SINR: ‘CRI-RSRP’, ‘CRI-SINR’, ‘SSB-Index-RSRP’, ‘SSB-Index-SINR’, ‘CRI-RSRP-Index’, ‘SSB-Index-RSRP-Index’, ‘CRI-SINR-Index’, ‘SSB-Index-SINR-Index’.
[0287] k = 1 for CSI reports not carrying L1-RSRP or L1-SINR.
[0288] c represents the cell index of the serving cell.
[0289] N cells represents the serving cell limit of the terminal (N cells is the value of the higher layer parameter maxNrofServingCells). The serving cell limit can also be understood as the maximum value of the number of serving cells.
[0290] s represents the reportConfigID of the CSI report;
[0291] M s represents the maximum number of CSI report configurations of the terminal (M s is the value of the higher layer parameter maxNrofCSI-ReportConfigurations). s
[0292] The priority of the first CSI report is taken as an example to explain the determination of the priority of multiple CSI reports:
[0293] The indication parameter k = 1 corresponding to the first CSI report whether to carry the first reporting quantity;
[0294] The reportConfigID of the first CSI report: in the scene of CSI report configured by LTM-CSI-ReportConfig, s represents the CSI report configuration ID of LTM IDLTM-CSI-ReportConfigID; otherwise, s represents the CSI report configuration ID.
[0295] The M s of the first CSI report: in the scene of CSI report configured by LTM-CSI-ReportConfig, M s The value of the maximum number of CSI report configurations for LTM (maxNrofLTM-CSI-ReportConfigurations). Otherwise, M s Indicates the maximum number of CSI report configurations.
[0296] The cell index c corresponding to the first CSI report: In the scenario of CSI report configured using LTM-CSI-ReportConfig, c is the index value of the serving cell that configures the report configuration. Otherwise, c indicates the cell index of the serving cell of the terminal.
[0297] Based on the above information and formula, the priority of the first CSI report is determined.
[0298] In some embodiments, the first cell and the second cell are both non-serving cells of the terminal, and the priority of the first CSI report and the second CSI report can be determined based on the above information and formula (1).
[0299] Optionally, the first CSI report is CSI of a non-serving cell, and the first CSI report contains at least one of the reporting quantities PMI, RI, CQI, LI, and CRI; the second CSI report is also CSI of a non-serving cell, and the second CSI report contains L1-RSRP or L1-SINR. The other values in the formula corresponding to the first CSI report and the second CSI report are the same, only the reporting quantities are different. Then based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is greater than the priority value corresponding to the second CSI report, and the greater the priority value, the lower the priority, so the priority of the first CSI report is lower than the priority of the second CSI report.
[0300] Optionally, the first CSI report is a CSI report of a non-serving cell, and the first CSI report contains at least one of the reporting quantities PMI, RI, CQI, LI, and CRI; the second CSI report is also a CSI report of a non-serving cell, and the second CSI report contains at least one of the reporting quantities PMI, RI, CQI, LI, and CRI. The cell indexes corresponding to the first CSI report and the second CSI report are different, such as the cell index corresponding to the first CSI report is 0 and the cell index corresponding to the second CSI report is 1, and the other values in the formula are the same, only the cell indexes are different. Then based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report, and the greater the priority value, the lower the priority, so the priority of the first CSI report is greater than the priority of the second CSI report.
[0301] Optionally, the first CSI report is a CSI report for a non-serving cell, and the first CSI report contains at least one of PMI, RI, CQI, LI and CRI as the reported quantity; the second CSI report is also a CSI report for a non-serving cell, and the second CSI report also contains at least one of PMI, RI, CQI, LI and CRI as the reported quantity. The first CSI report and the second CSI report correspond to different CSI report configuration IDs of the LTM, for example, the first CSI report corresponds to a CSI report configuration ID of 0 of the LTM, and the second CSI report corresponds to a CSI report configuration ID of 1 of the LTM, and other values in the formula are the same, only the CSI report configuration ID of the LTM is different. Then, based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report, and the larger the priority value, the lower the priority, so the priority of the first CSI report is higher than the priority of the second CSI report.
[0302] It should be noted that the above only gives an example in which only one value in the formula (1) corresponding to the first CSI report and the second CSI report is different, and the case where multiple parameters are different is also included in the present application, which is not listed here.
[0303] In some embodiments, the first cell is a non-serving cell of the terminal, the second cell is a serving cell of the terminal, and the priority of the first CSI report is pre-configured to be higher than the priority of the second CSI report.
[0304] Optionally, the first cell is a non-serving cell of the terminal, and the first CSI report corresponds to a CSI of the non-serving cell, for example, the first CSI report contains at least one of PMI, RI, CQI, LI and CRI as the reported quantity. The second cell is a serving cell of the terminal, and the second CSI report corresponds to a CSI report of the serving cell. In this case, the priority of the first CSI report is directly higher than the priority of the second CSI report. That is, the priority of the first CSI report and the second CSI report can be determined based on the above information and formula (1).
[0305] In some embodiments, the first cell is a non-serving cell of the terminal, the second cell is a serving cell of the terminal, and the priority of the first CSI report and the second CSI report can also be determined based on the above information and formula (1). For specific examples, reference can be made to the embodiments when the first cell is a non-serving cell of the terminal and the second cell is a non-serving cell of the terminal, which will not be repeated here.
[0306] In step S2106, according to the priority of each CSI report in the plurality of CSI reports, at least one CSI report with low priority in the plurality of CSI reports is not updated.
[0307] In some embodiments, the CSI report with the lowest priority among the plurality of CSI reports can not be updated.
[0308] In some embodiments, the last N CSI reports among the plurality of CSI reports sorted in descending order of priority can not be updated.
[0309] In some embodiments, the partial CSI reports among the plurality of CSI reports can be updated according to the priority of the plurality of CSI reports. Optionally, the plurality of CSI reports can be sorted in descending order of priority, and further, the partial CSI reports can be determined from the plurality of CSI reports according to the order, and the partial CSI can be updated. It can be understood that the partial CSI occupies a CSI processing unit that is less than or equal to the second CSI processing unit. Accordingly, the remaining CSI reports among the plurality of CSI reports other than the partial CSI reports can not be updated. It can be understood that the priority of the remaining CSI reports is lower than the priority of the partial CSI reports.
[0310] In some embodiments, the plurality of CSI reports can be sorted in descending order of priority, and further, at least one CSI report among the plurality of CSI reports can be updated according to the order. That is, the plurality of CSI reports can be updated in descending order, and in response to the CSI processing unit occupied by the CSI report being updated being greater than the second CSI processing unit supported by the terminal, the updating is stopped, that is, the subsequent CSI report is not updated.
[0311] It can be understood that, due to the first CSI processing unit being greater than the second CSI processing unit, the terminal can not update the CSI with a low priority among the plurality of CSI reports, that is, the CSI report with the low priority still contains the CSI calculated or determined at the last time.
[0312] In some embodiments, the terminal can perform CSI measurement on the CSI report according to the priority of the CSI report and the measurement configuration of the CSI report, to update the CSI report. Optionally, the terminal can perform CSI measurement and calculation on the plurality of CSI reports according to the priority of the CSI report and the measurement configuration of the CSI report, to update the CSI report with a high priority.
[0313] In step S2107, the terminal sends the plurality of CSI reports to the network device.
[0314] In some embodiments, after the priority of the plurality of CSI reports is updated, the terminal sends the plurality of CSI reports to the network device. It can be understood that the plurality of CSI reports include CSI reports with different priorities, wherein the CSI report with high priority contains updated CSI, and the CSI report with low priority contains un-updated CSI.
[0315] In some embodiments, the CSI report with the highest priority in the plurality of CSI reports contains the updated CSI report, and the remaining CSI reports contain un-updated CSI reports.
[0316] In some embodiments, part of the CSI reports in the plurality of CSI reports contain updated CSI reports, and the remaining CSI reports contain un-updated CSI reports. It can be understood that the priority of the part of the CSI reports is higher than the priority of the remaining CSI reports, and the part of the CSI reports occupies the overall CSI processing unit less than or equal to the second CSI processing unit.
[0317] In some embodiments, the terminal can send the plurality of CSI reports to the network device based on the CSI measurement configuration information in the second information. Alternatively, the terminal can determine the reporting type, reporting content, reporting frequency, reporting occasion, and other parameters of the CSI according to the CSI measurement configuration, and report the CSI according to the above parameters.
[0318] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2107. For example, step S2102 can be implemented as an independent embodiment, step S2104 can be implemented as an independent embodiment, step S2105 can be implemented as an independent embodiment, step S2106 can be implemented as an independent embodiment, step S2105+S2106 can be implemented as an independent embodiment, but not limited thereto.
[0319] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.
[0320] In the embodiments of the present disclosure, when the terminal determines that the first CSI processing unit occupied by the plurality of CSI reports in the same time unit is greater than the second CSI processing unit supported by the terminal, the terminal can update the CSI report with high priority in the plurality of CSI reports according to the priority of the CSI, and not update the CSI report with low priority. By not updating the CSI report with low priority, resource conflicts of the CSI processing unit can be avoided.
[0321] FIG. 2B is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2B, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises the following steps.
[0322] In step S2201, the network device sends first information to the terminal.
[0323] The optional implementation of step S2201 can refer to the optional implementation of step S2101 in FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which will not be repeated here.
[0324] In step S2202, the terminal determines the first CSI report and the second CSI report that need to be processed in the same time unit according to the first information.
[0325] In some embodiments, the first CSI report is a CSI report of at least one first cell, and the second CSI report is a CSI report of at least one second cell, wherein the first cell is a non-serving cell of the terminal, and the second cell is one of a serving cell and a non-serving cell of the terminal.
[0326] In some embodiments, the first cell is not currently a serving cell of the terminal, that is, the first cell is currently a non-serving cell of the terminal. It can be understood that the first cell is not currently a serving cell of the terminal, that is, when the terminal determines the reference signal resource of the first cell, the first cell is not yet a serving cell of the terminal.
[0327] In some embodiments, the first cell can be one of a candidate cell, a neighbor cell and a target cell of the terminal. It can be understood that when the terminal determines the first reference signal resource, the first cell is not yet a serving cell of the terminal. For example, the first cell can be a cell to which the terminal is about to switch to, and after the terminal switches to the first cell, the first cell becomes a serving cell of the terminal.
[0328] In some embodiments, the second CSI report can be a CSI of a serving cell or can not be a CSI of a serving cell, for example, the second CSI report can be a measurement report of L1-RSRP or L1-SNIR of a non-serving cell.
[0329] In some embodiments, in the scenario that the first cell and the second cell are different non-serving cells, the first CSI report includes at least one of the following information: PMI, RI, CQI, LI and CRI. The second CSI report includes at least one of the following information: PMI, RI, CQI, LI and CRI.
[0330] In some embodiments, the first cell is a non-serving cell, and the second cell is the same non-serving cell, and the first CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI. The second CSI report includes at least one of the following: none, CRI-RI-PMI, CRI-RI-i1, CRI-RI-i1-CQI, CRI-RSRP, CRI-SINR, SSB-Index-RSRP, SSB-Index-SINR, CRI-RI-LI-PMI-CQI, CRI-RSRP-Index, SSB-Index-RSRP-Index, CRI-SINR-Index, SSB-Index-SINR-Index, TDCP. Alternatively, the second CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI, in which case the reporting amount in the first CSI report and the second CSI report is the same.
[0331] In some embodiments, the first cell is a non-serving cell, and the second cell is a serving cell, and the first CSI report includes at least one of the following: PMI, RI, CQI, LI, and CRI. The second CSI report includes at least one of the following: CRI-RI-PMI, CRI-RI-i1, CRI-RI-i1-CQI, CRI-RSRP, CRI-SINR, SSB-Index-RSRP, SSB-Index-SINR, CRI-RI-LI-PMI-CQI, CRI-RSRP-Index, SSB-Index-RSRP-Index, CRI-SINR-Index, SSB-Index-SINR-Index, TDCP.
[0332] In step S2203, the network device sends the second information to the terminal.
[0333] The optional implementation of step S2203 can refer to the optional implementation of step S2103 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be described here.
[0334] In step S2204, the terminal determines the third CSI processing units of the first CSI report and the second CSI report respectively, and determines the total first CSI processing units occupied by the two CSI reports according to the third CSI processing units.
[0335] In some embodiments, the third CSI processing units occupied by the first CSI report are related to at least one of the following:
[0336] The number of the first cells corresponding to the first CSI report;
[0337] a number of CSI-RS resources for CSI measurement corresponding to the first CSI report;
[0338] a number of ports of the CSI-RS resources corresponding to the first CSI report;
[0339] a number of channel measurement resources for CSI measurement corresponding to the first CSI report;
[0340] a type of the first CSI report;
[0341] a reporting quantity of the first CSI report.
[0342] In some embodiments, the type of the first CSI report can include, but is not limited to, the following types set in a codebook: type I-single panel (typeI-SinglePanel), type II-multi panel (typeI-multiPanel), type II-port selection (typeII-PortSelection), type II (typeII), enhanced type II-port selection (enhanced typeII-PortSelection), and enhanced type II (typeII).
[0343] In some embodiments, the type of the CSI of the first CSI report can be single CSI with wideband frequency-granularity.
[0344] In some embodiments, the reporting quantity of the first CSI report can be any of the following:
[0345] ‘CRI-RI-PMI-CQI’, ‘CRI-RI-LI’, and ‘CRI-RI-LI-PMI-CQI’.
[0346] In some embodiments, the first CSI report occupies the third CSI processing unit differently from the second CSI report. For example, the first CSI report occupies the third CSI processing unit differently from the second CSI report, when the first CSI report has a reporting quantity of one of ‘CRI-RI-PMI-CQI’, ‘CRI-RI-LI’, and ‘CRI-RI-LI-PMI-CQI’, and the second CSI report has a reporting quantity of one of ‘CRI-RSRP’, ‘CRI-SNIR’, ‘SSB-Index-RSRP’, ‘SSB-Index-SINR’, ‘CRI-RSRP-Index’, ‘SSB-Index-RSRP-Index’, ‘CRI-SINR-Index’, and ‘SSB-Index-SINR-Index’.
[0347] In some embodiments, the determining of the third CSI processing unit occupied by the first CSI report can comprise:
[0348] determining the number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement corresponding to the first CSI report, the number of ports of the CSI-RS resources corresponding to the first CSI report, the number of channel measurement resources for CSI measurement corresponding to the first CSI report, the type of the first CSI report, and the reporting quantity corresponding to the first CSI report, and determining the third CSI processing unit occupied by the first CSI report based on at least one of the above information.
[0349] In some embodiments, the number of first cells corresponding to the first CSI report, the number of CSI-RS resources for CSI measurement, the number of ports of the CSI-RS resources, the number of channel measurement resources for CSI measurement, the type of the first CSI report, and the reporting quantity corresponding to the first CSI report can be determined based on the CSI measurement configuration corresponding to the first CSI report of the network device.
[0350] In some embodiments, the third CSI processing unit of the second CSI report is determined based on at least one of:
[0351] the number of second cells corresponding to the second CSI report;
[0352] the number of CSI-RS resources for CSI measurement corresponding to the second CSI report;
[0353] the number of ports of the CSI-RS resources corresponding to the second CSI report;
[0354] the number of channel measurement resources for CSI measurement corresponding to the second CSI report;
[0355] a type of the second CSI report;
[0356] a reporting quantity of the second CSI report.
[0357] The number of second cells corresponding to the second CSI, the number of CSI-RS resources for CSI measurement corresponding to the second CSI report, the number of ports of the CSI-RS resources corresponding to the second CSI report, the number of channel measurement resources for CSI measurement corresponding to the second CSI report, the type of the second CSI report, and the reporting quantity corresponding to the second CSI report are determined based on the above information, and the third CSI processing unit occupied by the second CSI report is determined based on the above information.
[0358] In some embodiments, after determining the third CSI processing unit occupied by the first CSI report and the second CSI report respectively, the third CSI processing units occupied by the two CSIs can be summed up to obtain the total first CSI processing units occupied by the two CSI reports.
[0359] In step S2205, in response to the first CSI processing unit being greater than the second CSI processing unit supported by the terminal, the priority of the first CSI report and the second CSI report is determined.
[0360] whether the first CSI report corresponds to an indication parameter k = 1 carrying the first reporting quantity;
[0361] The CSI report configuration identifier corresponding to the first CSI report: in the scenario of using LTM-CSI-ReportConfig to configure the CSI report, s represents the CSI report configuration ID of the LTM, i.e. IDLTM-CSI-ReportConfig; otherwise, s represents the CSI report configuration identifier.
[0362] The M corresponding to the first CSI report s : in the scenario of using LTM-CSI-ReportConfig to configure the CSI report, M s is the value of the maximum number of CSI report configurations (maxNrofLTM-CSI-ReportConfigurations) of the upper layer parameter LTM. Otherwise, M s represents the maximum number of CSI report configurations.
[0363] The cell index c corresponding to the first CSI report: in the scenario of using LTM-CSI-ReportConfig to configure the CSI report, c is the index value of the serving cell of the configured report configuration. Otherwise, c represents the cell index of the serving cell of the terminal.
[0364] Based on the above information and the formula, the priority of the first CSI report is determined.
[0365] In some embodiments, the first cell and the second cell are both non-serving cells of the terminal, and the priorities of the first CSI report and the second CSI report can be determined based on the above information and formula (1).
[0366] Optionally, the first CSI report is CSI of a non-serving cell, and the reporting quantity contained in the first CSI report is at least one of PMI, RI, CQI, LI and CRI; the second CSI report is also CSI of a non-serving cell, and the reporting quantity contained in the second CSI report is L1-RSRP or L1-SINR. However, other values in the formulas corresponding to the first CSI report and the second CSI report are the same, only the reporting quantity is different. Then, based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is greater than the priority value corresponding to the second CSI report, and the greater the priority value, the lower the priority. Therefore, the priority of the first CSI report is lower than the priority of the second CSI report.
[0367] Optionally, the first CSI report is CSI of a non-serving cell, and the reporting quantity contained in the first CSI report is at least one of PMI, RI, CQI, LI and CRI; the second CSI report is also CSI of a non-serving cell, and the reporting quantity contained in the second CSI report is at least one of PMI, RI, CQI, LI and CRI. However, the cell indexes corresponding to the first CSI report and the second CSI report are different, for example, the cell index corresponding to the first CSI report is 0, and the cell index corresponding to the second CSI report is 1, and other values in the formulas are the same, only the cell index is different. Then, based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report, and the greater the priority value, the lower the priority. Therefore, the priority of the first CSI report is greater than the priority of the second CSI report.
[0368] Optionally, the first CSI report is a CSI report for a non-serving cell, and the first CSI report contains at least one of PMI, RI, CQI, LI and CRI. The second CSI report is also a CSI report for a non-serving cell, and the second CSI report also contains at least one of PMI, RI, CQI, LI and CRI. The first CSI report and the second CSI report correspond to different CSI report configuration IDs of the LTM, for example, the first CSI report corresponds to a CSI report configuration ID of 0 of the LTM, and the second CSI report corresponds to a CSI report configuration ID of 1 of the LTM. Other values in the formula are the same, only the CSI report configuration ID of the LTM is different. Then, based on the above formula (1), it is determined that the priority value corresponding to the first CSI report is less than the priority value corresponding to the second CSI report, and the larger the priority value, the lower the priority. Therefore, the priority of the first CSI report is higher than the priority of the second CSI report.
[0369] It should be noted that the above only gives an example in which only one value in the formula (1) corresponding to the first CSI report and the second CSI report is different, and the case in which multiple parameters are different is also included in the present application, which is not listed here.
[0370] In some embodiments, the first cell is a non-serving cell of the terminal, the second cell is a serving cell of the terminal, and the priority of the first CSI report is higher than the priority of the second CSI report.
[0371] Optionally, the first cell is a non-serving cell of the terminal, and the first CSI report corresponds to CSI of the non-serving cell, for example, the first CSI report contains at least one of PMI, RI, CQI, LI and CRI. The second cell is a serving cell of the terminal, and the second CSI report corresponds to CSI report of the serving cell. In this case, the priority of the first CSI report is directly higher than the priority of the second CSI report. That is, the priority of the first CSI report and the second CSI report can be determined based on the above information and formula (1).
[0372] In some embodiments, the first cell is a non-serving cell of the terminal, the second cell is a serving cell of the terminal, and the priority of the first CSI report and the second CSI report can also be determined based on the above information and formula (1). For specific examples, reference can be made to the embodiments when the first cell is a non-serving cell of the terminal and the second cell is a non-serving cell of the terminal, which will not be repeated here.
[0373] In step S2206, the CSI with lower priority in the first CSI report and the second CSI report is not updated.
[0374] In some embodiments, if the priority of the first CSI report is higher than the priority of the second CSI report, the first CSI report is updated and the second CSI report is not updated.
[0375] In some embodiments, if the priority of the second CSI report is higher than the priority of the first CSI report, the second CSI report is updated and the first CSI report is not updated.
[0376] The optional implementation of step S2206 can refer to the optional implementation of step S2106 in FIG. 2A and other associated parts in the embodiments involved in FIG. 2A, which will not be repeated here.
[0377] In step S2207, the terminal sends the first CSI report and the second CSI report to the network device.
[0378] In some embodiments, if the priority of the first CSI report is higher than the priority of the second CSI report, the first CSI report received by the network device is the updated CSI report, and the second CSI report is the un-updated CSI report.
