It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0107] In this disclosure, data transmission between network devices and terminals is based on beamforming. Specifically, the uplink transmission of PUSCH between network devices and terminals can be enhanced using Multi-TRP / Multi-panel. The uplink transmission schemes for PUSCH include codebook-based uplink transmission and non-codebook-based uplink transmission schemes.

[0108] Among related technologies, simultaneous uplink transmission based on codebooks across multiple terminals is supported (STxMP). In this codebook-based simultaneous uplink transmission, the terminal needs to configure at most one Sounding Reference Signal (SRS) resource set for codebook-based uplink transmission. The SRS resource set can be configured with multiple SRS resources, and the network device will determine the appropriate SRS resource set based on the number of SRS resources (N) in the set. SRS )feedback The SRS resource indicator (SRI) is used to select an SRS resource via the SRI.

[0109] The following table, Tables 1-3, illustrates the method for SRI to indicate multiple SRS resources. In Tables 1-3, SRI(s) represents the number of SRIs indicated, and N... SRS This represents the number of SRS resources.

[0116] In codebook-based PUSCH transmission, the network device determines and notifies the terminal of the actual transmission precoding matrix (TPMI) and transmission layer number (RI). In subsequent uplink transmissions, the terminal needs to precode the data using the TPMI and RI specified by the network device. Simultaneously, the precoded data is mapped to the corresponding antenna port according to the spatial filter (SpatialRelation Info) corresponding to the SRS resource indicated by the SRI.

[0117] Tables 4 to 12 below are TPMI tables used to indicate TPMI and RI.

[0136] Here, "Bit field mapped to index" indicates the bit field mapped to the index, and "codebookSubset" represents a subset of the codebook. The transmission capabilities of the codebook subset include: fullyAndPartialAndNonCoherent (fully coherent transmission), partiallyAndNonCoherent (partially coherent transmission), and nonCoherent (non-coherent transmission). Taking Table 4 above as an example, Table 4 shows the precoding information and number of layers in the codebook subset corresponding to a 4-antenna port and a maximum rank of 2, 3, or 4.

[0137] In Tables 4 to 12 above, each TPMI is used to indicate a precode, and Table 13 below shows the codewords for single-layer transmission of the corresponding 4-antenna port.

[0139]

[0140] In the research on relevant communication protocols, the physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH) are enhanced.

[0141] In non-codebook-based PUSCH transmission, the terminal needs to configure at most one SRS resource set for non-codebook-based uplink transmission. The SRS resource set can be configured with multiple SRS resources, and the network device will determine the appropriate SRS resource set based on the number of SRS resources (N) in the set. SRS The maximum number of data layers to be transmitted (maxRank) is fed back to the SRI to indicate the selection of SRS resources.

[0142] The following examples, using Tables 14-17, illustrate the SRI's indication method for multiple SRS resources under different maximum data transmission layers. In Table 14, the maxRank value is 1; in Table 15, it is 2; in Table 16, it is 3; and in Table 17, it is 4.

[0150]

[0151] Uplink PUSCH transmission is directed to multiple base station TRPs. For example, in the cooperative transmission under TDM mode, the same information on the PUSCH is sent to different TRPs of the base station at different times through different transmission occupancy (TO) in the time domain. This method has relatively low requirements for terminal capabilities, does not require the ability to transmit beams simultaneously, and has a large transmission delay.

[0152] For uplink, the actual spatial characteristics of the PUSCH channels traversed by different panels / TRP / TCI may vary greatly. Therefore, it is assumed that the QCL-D of the PUSCH channels are different for different transmission directions.

[0153] The PUSCH enhancement based on Multi-TRP can schedule multi-panel / TRP transmissions based on a single PDCCH, such as a single downlink control information (S-DCI). Figure 2 A schematic diagram of an MP-MTRP transmission scenario under S-DCI scheduling is shown. (See also...) Figure 2 As shown, the terminal UE sends TPMI1 to TRP1 on panel1 and TPMI2 to TRP2 on panel2. Multi-panel / TRP transmission can also be scheduled based on different PDCCHs, such as multiple downlink control information (M-DCI). Figure 3 A schematic diagram of an MP-MTRP transmission scenario under M-DCI scheduling is shown.

[0154] In M-TRP transmission based on non-codebook and codebook in related technologies, the SRI field in DCI indicates the SRS resource in the SRS resource set. Since R17 supports two SRS resource sets, in M-TRP PUSCH repeat transmission based on non-codebook, DCI format 0_1 / 0_2 contains two SRI fields associated with the two SRS resource sets. Each SRI field is a TRP indicator SRI. The design of the first SRI field is based on the R15 / 16 framework, and all repeat transmissions use the same number of layers.

[0155] For non-codebook-based transmissions, the first SRI field is used to determine the elements in the second SRI field, and the second SRI field contains only SRI combinations associated with the layer number indicated by the first SRI field. The number of bits N2 in the second SRI field is determined by the maximum number of code points per transmission layer among all transmission layers associated with the first SRI field.

[0156] For multi-panel uplink synchronous transmission, the cooperative transmission scheduling of a TB (Transport Block) for a PUSCH based on a single DCI includes a variety of different transmission schemes. Each transmission scheme is briefly described below.

[0157] One approach is the SDM (Space Division Multiplexing) scheme: a TB (Transmission Block) of the PUSCH is transmitted to two different TRPs on the same time-frequency resources through corresponding DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission timings (TO) are associated with different TCI (Transmission Configuration Indicator) states, i.e., beams. Based on this, the SDM scheme is further divided into two types: SDM-A and SDM-B. In SDM-A, different parts of a TB of the PUSCH are transmitted to two different TRPs on the same time-frequency resources through corresponding DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission timings (TO) are associated with different TCI states, i.e., beams. In SDM-B, repetitions of the same TB corresponding to different RV versions of the PUSCH are transmitted to two different TRPs on the same time-frequency resources through corresponding DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission timings (TO) are associated with different TCI states, i.e., beams.

[0158] Another approach is the SFN (Single Frequency Network) multiplexing scheme: A TB of PUSCH transmits to two different TRPs on the same time-frequency resources through the same DMRS port or port combination allocated on different Panels. Different Panels / TRPs / transmission times TO are associated with different TCI states, i.e., beams.

[0159] For simultaneous uplink PUSCH transmission based on multiple terminal panels, one or more of the above schemes will be supported.

[0160] This disclosure provides a Physical Uplink Shared Channel (PUSCH) communication method. By configuring the maximum number of transmission layers, codebook parameters, and SRS resource set of the terminal in PUSCH transmission, it solves the problem of configuring PUSCH transmission resources associated with SRI / TPMI under STxMP transmission, supports multi-panel transmission mechanism of the terminal, and enables PUSCH transmission to support higher transmission rate and throughput while ensuring the flexibility of the terminal.

[0161] Figure 4 This is a flowchart illustrating a Physical Uplink Shared Channel (PUSCH) communication method according to an exemplary embodiment, such as... Figure 4As shown, the Physical Uplink Shared Channel (PUSCH) communication method used in a terminal includes the following steps.

[0162] In step S11, in response to determining that the terminal supports uplink multi-antenna panel simultaneous transmission of STxMP transmission, the PUSCH transmission resource configuration parameters are configured.

[0163] Among them, the PUSCH transmission resource configuration parameters correspond to the terminal supporting symmetric panel transmission and / or asymmetric panel transmission. The PUSCH transmission resource configuration parameters include at least one of the following: maximum number of transmission data layers, codebook parameters, and SRS resource set configuration parameters.

[0164] The SRS resource set configuration is applied to codebook-based transmissions and / or non-codebook-based transmissions.

[0165] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, a set of symmetric panels or a set of asymmetric panels corresponds to a set of PUSCH transmission resource configuration parameters.

[0166] A set of PUSCH transmission resource configuration parameters may include one or more of the following: maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. For example, a set of PUSCH transmission resource configuration parameters may include the maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. Alternatively, a set of PUSCH transmission resource configuration parameters may include pairwise combinations of the maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. For example, a set of PUSCH transmission resource configuration parameters may include the maximum number of data transmission layers and codebook parameters, or the maximum number of data transmission layers and SRS resource set configuration parameters, or the codebook parameters and SRS resource set configuration parameters. Or, a set of PUSCH transmission resource configuration parameters may include one of the following: the maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. For example, a set of PUSCH transmission resource configuration parameters may include the maximum number of data transmission layers, or codebook parameters, or SRS resource set configuration parameters.

[0167] Terminals are typically configured with multiple physical panels, and the capabilities of different panels may be the same or different. For example, panels with different capabilities may have different numbers of SRS ports, and / or support different maximum data transmission layers, and / or correspond to different transmit powers, etc.

[0168] Network devices determine whether a terminal is currently suitable for simultaneous uplink multi-panel transmission. If the terminal is suitable for simultaneous uplink multi-panel transmission and is scheduled for this purpose, the network device will directly or indirectly instruct the relevant transmission. This relevant transmission includes the terminal's specific beamforming information, the number of transmission data layers used, the Demodulation Reference Signal (DMRS) port allocation, and precoded indication information, etc.

[0169] In one example, symmetrical panel transmission refers to transmission based on a group of panels with identical capabilities within a terminal's multi-panel architecture. Specifically, a symmetrical panel can be two panels with the same number of SRS ports, the same maximum data transmission layer count, and the same transmit power.

[0170] In one example, asymmetric panel transmission refers to transmission based on a set of panels with different capabilities among multiple panels in a terminal. Specifically, the asymmetric panels can be two panels with different numbers of SRS ports, and / or different maximum data transmission layers, and / or different transmit powers.

[0171] In this embodiment of the disclosure, when the network device determines that the terminal supports simultaneous transmission of multiple uplink panels, it configures the PUSCH transmission resource configuration parameters corresponding to the symmetric panel and / or asymmetric panel of the terminal, so that the network device instructs the terminal to dynamically switch between M-TRP and S-TRP through the SRS resource indication set, thereby realizing the indication scheme of different precoding indications in different transmission modes.

[0172] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the maximum number of data transmission layers includes the maximum number of transmission layers supported by different panels in symmetric and / or asymmetric panel transmission supported by the terminal.

[0173] In this embodiment of the disclosure, the maximum number of data transmission layers may include a first maximum number of data transmission layers and / or a second maximum number of data transmission layers.

[0174] The first maximum data transmission layer is the maximum number of data layers that the terminal's corresponding panel can use when transmitting data in M-TRP and / or S-TRP transmission states. When the first maximum data transmission layer is the same for different SRS resource sets supported by the terminal, the first maximum data transmission layer can be represented as maxRank. When the first maximum data transmission layer is different for different SRS resource sets supported by the terminal, the first maximum data transmission layer can be represented as maxRank1 and maxRank2, respectively. The second maximum data transmission layer is the maximum number of data layers that the terminal's corresponding panel can use when transmitting data in S-TRP transmission states. When the second maximum data transmission layer is the same for different SRS resource sets supported by the terminal, the second maximum data transmission layer can be represented as maxRank'. When the second maximum data transmission layer number is different for different SRS resource sets in the symmetric panel and / or asymmetric panel supported by the terminal, the second maximum data transmission layer number can be represented as maxRank1' and maxRank2' respectively.

[0175] For ease of description, in the embodiments of this disclosure, the maximum number of data layers that the corresponding panel of the terminal can use when transmitting data in M-TRP and / or S-TRP transmission states is called the first maximum number of data transmission layers, and the maximum number of data layers that the corresponding panel of the terminal can use when transmitting data in S-TRP transmission states is called the second maximum number of data transmission layers.

[0176] Among them, the maximum number of data transmission layers is the first maximum number of data transmission layers.

[0177] The first data transmission layer is the maximum number of data transmission layers supported by the panel corresponding to the terminal's communication based on M-TRP, and is also the maximum number of data transmission layers supported by the panel corresponding to the terminal's communication based on S-TRP.

[0178] In one example, the SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal correspond to the same first maximum data transmission layer.

[0179] Network devices can configure different SRS resource sets associated with different TRP transmission directions, with each panel corresponding to a different SRS resource set. An SRS resource set can include either a first SRS resource set or a second SRS resource set. In one example, the SRI indicator field indicates multiple TRP transmission states and corresponds to different TRPs, such as TRP1 and TRP2. In this case, the first set of PUSCH transmissions is sent to TRP1 (the first SRS resource set), and the second set of PUSCH transmissions is sent to TRP2 (the second SRS resource set). In S-TRP transmission mode, the SRS resource set corresponding to a panel can be either the first or second SRS resource set. In M-TRP transmission mode, the SRS resource set corresponding to a panel can be either the first or second SRS resource set.

[0180] For ease of description, in the embodiments of this disclosure, any two different SRS resource sets among the multiple SRS resource sets corresponding to the panel are referred to as the first SRS resource set and the second SRS resource set.

[0181] In one example, when maxRank = 4, and maxRank = 4 is used in both the first and second SRS resource sets, then in M-TRP transmission state, the first and second SRS resource sets each correspond to 2 data layers, and in S-TRP transmission state, the first and second SRS resource sets each correspond to 4 data layers. When maxRank' = 2, in S-TRP transmission state, the first and second SRS resource sets each correspond to 2 data layers. If maxRank is used in both the first and second SRS resource sets, then in M-TRP transmission state, the first and second SRS resource sets also each correspond to 2 data layers, and maxRank = 4.

[0182] In this context, different SRS resource sets in the symmetric panels supported by the terminal correspond to the same first maximum data transmission layer.

[0183] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer number is used simultaneously for both the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. Additionally, the first transmission data layer number is used for either the first SRS resource set or the second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first SRS resource set and the second SRS resource set correspond to the same first maximum transmission data layer number.

[0184] In this context, different SRS resource sets in the asymmetric panels supported by the terminal correspond to the same first maximum data transmission layer.

[0185] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. Additionally, the first transmission data layer number is used for either the first SRS resource set or the second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first SRS resource set and the second SRS resource set correspond to the same first maximum transmission data layer number.

[0186] In this embodiment of the disclosure, different SRS resource sets of different panels in the asymmetric panel supported by the terminal correspond to different first maximum transmission data layers.

[0187] Different first maximum data transmission layers refer to the different maximum data transmission layers supported by the corresponding panel when the terminal communicates based on M-TRP. Different first maximum data transmission layers are configured independently and used for the first SRS resource set and the second SRS resource set respectively.

[0188] In one example, when two different first maximum data transmission layers are configured independently, namely maxRank1 and maxRank2, maxRank1 is used for the first SRS resource set corresponding to the panel where the terminal communicates based on M-TRP, and maxRank2 is used for the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP.

[0189] The maximum number of data transmission layers is the second maximum number of data transmission layers.

[0190] The second maximum number of data transmission layers is the maximum number of data transmission layers supported by the panel corresponding to the terminal's communication based on S-TRP.

[0191] In the case where the terminal supports symmetrical panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel that the terminal communicates based on M-TRP correspond to the same first maximum transmission data layer number, and the first SRS resource set or the second SRS resource set corresponding to the panel that the terminal communicates based on S-TRP correspond to the second maximum transmission data layer number.

[0192] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP. The second transmission data layer number is used for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP correspond to the same first maximum transmission data layer number, and the first or second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP corresponds to the second maximum transmission data layer number. The first maximum transmission data layer number is different from the second maximum transmission data layer number.

[0193] In the case where the terminal supports asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP correspond to the same first maximum transmission data layer number, and the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP correspond to the second maximum transmission data layer number.

[0194] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP. The second transmission data layer number is used for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP correspond to the same first maximum transmission data layer number, and the first or second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP corresponds to the second maximum transmission data layer number. The first maximum transmission data layer number is different from the second maximum transmission data layer number.

[0195] In cases where the terminal supports asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP correspond to different first maximum transmission data layers. Conversely, for panels used for communication based on S-TRP, the first SRS resource set or the second SRS resource set corresponding to the panel corresponds to the same second maximum transmission data layer.

[0196] In this embodiment of the disclosure, the same second maximum data transmission layer number may include maxRank from capability reporting.

[0197] In one example, when two different first maximum transmission data layers are independently configured, such as maxRank1 and maxRank2, maxRank1 and maxRank2 are used respectively for the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. The first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP corresponds to the maxRank from the capability reporting.

[0198] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, different SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal correspond to different second maximum transmission data layers.

[0199] Where the terminal supports symmetric panel and / or asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel communicating based on M-TRP correspond to the same first maximum transmission data layer number. Conversely, for panels communicating based on S-TRP, the first SRS resource set or the second SRS resource set corresponding to the panel corresponds to different second maximum transmission data layers.

[0200] In this embodiment of the disclosure, the different second maximum data transmission layer numbers may include maxRank1' and maxRank2' from capability reporting.

[0201] In one example, when the same first maximum data transmission layer is configured independently, it can be maxRank. maxRank is used simultaneously for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP. maxRank1' or maxRank2' from capability reporting is used for the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, respectively.

[0202] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the SRS resource sets of different panels in the asymmetric panels supported by the terminal correspond to different second maximum transmission data layers.

[0203] In cases where the terminal supports asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP correspond to different first maximum transmission data layers. Similarly, for panels used for communication based on S-TRP, the first SRS resource set or the second SRS resource set corresponding to the panel corresponds to different second maximum transmission data layers.

[0204] In this embodiment of the disclosure, the different second maximum data transmission layer numbers may include maxRank1' and maxRank2' from capability reporting.

[0205] In one example, when two different first maximum transmission data layers are independently configured, such as maxRank1 and maxRank2, maxRank1 and maxRank2 are used respectively for the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. The maxRank1' or maxRank2' from capability reporting is used respectively for the first SRS resource set or the second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP.

[0206] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the codebook parameters include at least one of the following: codebook subset and full power mode.

[0207] In this embodiment of the disclosure, different panels in a symmetric panel supported by the terminal correspond to the same subset of the codebook and / or the same full-power mode. Alternatively, different panels in asymmetric panels supported by the terminal correspond to the same subset of the codebook and / or the same full-power mode. Alternatively, different panels in asymmetric panels supported by the terminal correspond to different subsets of the codebook and / or different full-power modes.

[0208] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for M-TRP-based communication, and also for either the first or second SRS resource set corresponding to the panel used for S-TRP-based communication. Different panels within the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode.

[0209] For example, if the terminal supports symmetrical panel transmission, and the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panels communicating based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank. maxRank is used simultaneously for the first and second SRS resource sets corresponding to the panels communicating based on S-TRP and / or M-TRP. In this case, different panels in the symmetrical panel are configured with the same codebook subset and / or the same full-power mode.

[0210] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP, and the second maximum transmission data layer number is used for either the first or second SRS resource set corresponding to the panel used for communication based on S-TRP. Different panels within the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode.

[0211] For example, if the terminal supports symmetrical panel transmission, the first maximum transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP. The second maximum transmission data layer is used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to `maxRank`, and the second maximum transmission data layer corresponds to `maxRank'`. `maxRank` is used for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, and `maxRank'` is used for both the first and second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in the symmetrical panel are configured with the same codebook subset and / or the same full-power mode.

[0212] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for M-TRP-based communication, and also for either the first or second SRS resource set corresponding to the panel used for S-TRP-based communication. Different panels in the symmetric panels supported by the terminal may correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal may correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal may correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal may correspond to different codebook subsets and the same full-power mode.

[0213] For example, if the terminal supports asymmetric panel transmission, and the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panels communicating based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank. maxRank is used simultaneously for the first and second SRS resource sets corresponding to the panels communicating based on S-TRP and / or M-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0214] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP, and the second maximum transmission data layer number is used for either the first or second SRS resource set corresponding to the panel used for communication based on S-TRP. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0215] For example, if the terminal supports asymmetric panel transmission, the first maximum transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP. The second maximum transmission data layer is used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to `maxRank`, and the second maximum transmission data layer corresponds to `maxRank'`. `maxRank` is used for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, and `maxRank'` is used for both the first and second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0216] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for M-TRP-based communication by the terminal, and different second maximum transmission data layers are used for either the first or second SRS resource sets corresponding to the panel used for S-TRP-based communication by the terminal. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0217] For example, the terminal supports asymmetric panel transmission. The first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP. Different independently configured second maximum transmission data layers are used respectively for the first or second SRS resource sets corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to `maxRank`, and the second maximum transmission data layer corresponds to `maxRank1'` or `maxRank2'`. `maxRank` is used simultaneously for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, and `maxRank1'` / `maxRank2'` are used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0218] In one example, when the terminal supports asymmetric panel transmission, different first maximum transmission data layers are used for the first and second SRS resource sets corresponding to the panels used for communication based on M-TRP, respectively, and the second maximum transmission data layer is used for the first or second SRS resource sets corresponding to the panels used for communication based on S-TRP. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0219] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. The second maximum transmission data layer from capability reporting is simultaneously used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to maxRank1 or maxRank2, and the second maximum transmission data layer corresponds to maxRank'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, while maxRank' is used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0220] In one example, when the terminal supports asymmetric panel transmission, different first maximum transmission data layers are used for the first and second SRS resource sets corresponding to the panels used for communication based on M-TRP, respectively, and different second maximum transmission data layers are used for the first or second SRS resource sets corresponding to the panels used for communication based on S-TRP. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0221] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. Different second maximum transmission data layers reported by the terminal are used for the first or second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. The first maximum transmission data layers correspond to maxRank1 or maxRank2, and the second maximum transmission data layers correspond to maxRank1' or maxRank2'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, and maxRank1' and maxRank2' are used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0222] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the SRS resource set configuration parameters include at least one of the following: the number of SRS resources in the SRS resource set and the number of ports for each SRS resource in the SRS resource set.

[0223] The SRS resource set configuration parameters can include either the number of SRS resources in the RS resource set or the number of ports for each SRS resource in the RS resource set, or they can include the number of SRS resources in the RS resource set and the number of ports for each SRS resource in the RS resource set.

[0224] In this embodiment of the disclosure, in response to the terminal using codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal is the same, and the number of ports for the SRS resources is the same. And / or in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal is the same.

[0225] The network device responds to the terminal by using codebook transmission. The configuration parameters of the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources and the number of ports of the SRS resources. The number of SRS resources and the number of ports of the SRS resources are the same.

[0226] In one example, in response to the terminal using codebook transmission, for an asymmetric panel with 2 antennas and 4 antennas, the number of ports for the SRS resources of both panels can only be configured according to the panel with the lower capability. That is, the number of ports for the SRS resources corresponding to the 4-antenna panel is configured according to the number of ports for the SRS resources of the 2-antenna panel, with the same number of ports (2).

[0227] The network device responds to the terminal by using codebook transmission. The configuration parameters of the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources and the number of ports of the SRS resources. The number of SRS resources and the number of ports of the SRS resources are the same.

[0228] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission, and the number of ports of SRS resources in different SRS resource sets of different panels supported by the terminal is the first maximum number of transmission data layers.

[0229] In one example, in response to the terminal using codebook transmission, the number of SRS resources and the number of ports for the SRS resources are the same in different SRS resource sets of different panels supported by the terminal. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and also for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of ports for the SRS resources is configured as the first maximum transmission data layer.

[0230] For example, in response to the terminal using codebook transmission, the terminal supports symmetric panel transmission, and when the first transmission data layer is configured to be used for both the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank, and the number of ports configured for SRS resources is maxRank.

[0231] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission, and the number of ports of SRS resources in different SRS resource sets of different panels supported by the terminal is the first maximum number of data transmission layers and / or the second maximum number of transmission layers.

[0232] In one example, in response to the terminal using codebook transmission, the number of SRS resources and the number of ports of the SRS resources are the same in different SRS resource sets of different panels supported by the terminal. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of ports of the SRS resources is configured as the first maximum transmission data layer and / or the second maximum transmission data layer. For example, the number of ports of all SRS resources in different SRS resource sets can be configured as the first maximum transmission data layer. Alternatively, the number of ports of all SRS resources in different SRS resource sets can be configured as the second maximum transmission data layer. Or, different SRS resource sets may include both the number of ports of SRS resources configured as the first maximum transmission data layer and the number of ports of SRS resources configured as the second maximum transmission data layer.

[0233] For example, in response to the terminal using codebook transmission, the terminal supports symmetric panel transmission. The first transmission data layer is configured to be used for the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP. The second maximum transmission data layer is configured to be used for the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP. The first maximum transmission data layer corresponds to maxRank, and the second maximum transmission data layer corresponds to maxRank'. At this time, the number of ports configured for SRS resources is maxRank and / or maxRank'.

[0234] The different SRS resource sets include both the number of ports of SRS resources configured for the first maximum data transmission layer and the number of ports of SRS resources configured for the second maximum data transmission layer. For example, in the case of a symmetrical panel with 4 antennas + 4 antennas, if the first maximum data transmission layer is 2 and the second maximum data transmission layer is 4, then the SRS resource set contains one or more SRS resources with 4 ports and one or more SRS resources with 2 ports. In this case, the terminal, in actual application, autonomously selects the corresponding SRS resource for transmission based on either M-TRP or S-TRP transmission.

[0235] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission, the terminal's full power mode is configured as full power mode 2, and the maximum number of SRS resources in the SRS resource set of different panels in the symmetrical panel supported by the terminal is 4.

[0236] If the network device responds to the terminal's full-power mode not being configured as full-power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 2. Alternatively, if the network device responds to the terminal's full-power mode not being configured as full-power mode 2, the maximum number of SRS resources in the different SRS resource sets of different panels in the symmetrical panel supported by the terminal is either the first maximum number of data transmission layers or the second maximum number of transmission layers.

[0237] In one example, in response to the terminal using codebook transmission, when the first maximum transmission data layer is configured to be used simultaneously for the first and second SRS resource sets corresponding to the panel for terminal communication based on M-TRP, and also for the first or second SRS resource set corresponding to the panel for terminal communication based on S-TRP: If the terminal's full power mode is configured as full power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 4. If the terminal's full power mode is not configured as full power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 2.

[0238] In one example, in response to the terminal using codebook transmission, when the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP, the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel used for communication based on S-TRP. If the terminal's full-power mode is configured as full-power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 4. If the terminal's full-power mode is not configured as full-power mode 2, the maximum number of SRS resources in different SRS resource sets of different panels in the symmetrical panel supported by the terminal can be either the first maximum transmission data layer or the second maximum transmission data layer, and either the first or second maximum transmission data layer can be greater than 2.

[0239] When a network device responds to a terminal using non-codebook transmission, the configuration parameters for the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources, and the number of SRS resources is the same.

[0240] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses non-codebook transmission, and the number of SRS resources in different SRS resource sets of different panels in the symmetrical panel supported by the terminal is the first maximum number of transmission data layers.

[0241] In one example, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric panels supported by the terminal is the same. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and also for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of SRS resources configured is the first maximum transmission data layer.

[0242] For example, in response to the terminal using non-codebook transmission, the terminal supports symmetric panel transmission, and when the first transmission data layer is configured to be used for both the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank, and the number of ports configured for SRS resources is maxRank.

[0243] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses non-codebook transmission, and the number of SRS resources in different SRS resource sets of different panels in the symmetrical panel supported by the terminal is either the first maximum number of data transmission layers or the second maximum number of transmission layers.

[0244] In one example, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric panel supported by the terminal is the same. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of SRS resources is configured as the first maximum transmission data layer and / or the second maximum transmission data layer. For example, the number of SRS resources in all different SRS resource sets can be configured as the first maximum transmission data layer. Alternatively, the number of SRS resources in all different SRS resource sets can be configured as the second maximum transmission data layer.

[0245] For example, in response to the terminal using non-codebook transmission, the terminal supports symmetric panel transmission. The first transmission data layer is configured to be used for the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP. The second maximum transmission data layer is configured to be used for the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP. The first maximum transmission data layer corresponds to maxRank, and the second maximum transmission data layer corresponds to maxRank'. At this time, the number of ports configured for SRS resources is maxRank and / or maxRank'.

[0246] The network device responds to the terminal by transmitting codebooks. The configuration parameters of the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources and the number of ports of the SRS resources.

[0247] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission. Different panels in the asymmetric panels supported by the terminal adopt different full-power configuration modes. The number of SRS resources in the different SRS resource sets corresponding to different full-power configuration modes is different, and the number of ports of the SRS resources is different.

[0248] In one example, when the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel used for terminal communication based on M-TRP, and the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel used for terminal communication based on S-TRP, different panels in the asymmetric panels supported by the terminal adopt different full-power configuration modes. The number of SRS resources in the SRS resource sets corresponding to different panels is different, and the number of ports for the SRS resources is also different.

[0249] For example, in response to the terminal using codebook transmission, the terminal supports asymmetric panel transmission. The first transmission data layer is configured for the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP. The second maximum transmission data layer is configured for the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP. The first maximum transmission data layer corresponds to maxRank, and the second maximum transmission data layer corresponds to maxRank'. At this time, it is considered that different panels in the asymmetric panels supported by the terminal adopt different full-power configuration modes, the number of SRS resources in the SRS resource set corresponding to different panels is different, and the number of ports of the SRS resources is different.

[0250] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the terminal uses codebook transmission. In different SRS resource sets of different panels supported by the terminal, the number of SRS resources is the same, but the number of ports for the SRS resources is different. And / or, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same.

[0251] In one example, different first maximum transmission data layers are configured for the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP by the terminal, respectively. A second maximum transmission data layer for acquiring capability reporting is configured for the first or second SRS resource set corresponding to the panel used for communication based on S-TRP by the terminal. In response to the terminal using codebook transmission, the network device uses codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same, and the number of ports for the SRS resources is different. Alternatively, the network device uses non-codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same. Or, the network device uses codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same, and the number of ports for the SRS resources is different. Furthermore, the network device also uses non-codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same.

[0252] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. The second maximum transmission data layer from capability reporting is simultaneously used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to maxRank1 or maxRank2, and the second maximum transmission data layer corresponds to maxRank'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, and maxRank' is used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP. In response to the terminal using codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the asymmetric panels supported by the terminal is the same, and the number of ports for the SRS resources is different. And / or in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the asymmetric panels supported by the terminal is the same.

[0253] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the terminal uses codebook transmission. The number of SRS resources and the number of ports for different SRS resources differ in different SRS resource sets of different panels within the asymmetric panels supported by the terminal. And / or, in response to the terminal using non-codebook transmission, the number of SRS resources differs in different SRS resource sets of different panels within the asymmetric panels supported by the terminal.

[0254] In one example, different first maximum transmission data layers are configured for the first and second SRS resource sets corresponding to the panels used for terminal communication based on M-TRP, respectively. Similarly, different second maximum transmission data layers are configured for the first or second SRS resource sets corresponding to the panels used for terminal communication based on S-TRP, respectively. In response to the terminal using codebook transmission, the network device employs different numbers of SRS resources and different numbers of ports for the SRS resources in different SRS resource sets of different panels supported by the terminal. Alternatively, the network device may employ non-codebook transmission, resulting in different numbers of SRS resources in different SRS resource sets of different panels supported by the terminal. Or, the network device may also employ non-codebook transmission, resulting in different numbers of SRS resources in different SRS resource sets of different panels supported by the terminal. Furthermore, the network device may also employ non-codebook transmission, resulting in different numbers of SRS resources in different SRS resource sets of different panels supported by the terminal.

[0255] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. Different reported second maximum transmission data layers are used for the first or second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. The first maximum transmission data layers correspond to maxRank1 or maxRank2, and the second maximum transmission data layers correspond to maxRank1' or maxRank2'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, and maxRank1' and maxRank2' are used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. In response to the terminal using codebook transmission, the number of SRS resources and the number of ports for the SRS resources differ in different SRS resource sets of different panels in the asymmetric panel supported by the terminal. Alternatively, the network device responds to the terminal by using non-codebook transmission, in which case the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is different. Or, the network device responds to the terminal by using codebook transmission, in which case the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is different, and the number of ports for the SRS resources is different, and the network device also responds to the terminal by using non-codebook transmission, in which case the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is different.

[0256] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the number of SRS resources and / or the number of ports of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal are determined based on a first maximum data transmission layer or a second maximum transmission layer.

[0257] In one example, in response to a terminal using codebook transmission, the number of SRS resources and / or the number of ports of the SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal are determined based on a first maximum data transmission layer or a second maximum data transmission layer.

[0258] In one example, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is determined based on a first maximum number of transmission data layers or a second maximum number of transmission layers.

[0259] In all the physical uplink shared channel (PUSCH) communication methods disclosed herein, the terminal supports the SDM transmission method for PUSCH transmission under STxMP transmission based on S-DCI or M-DCI scheduling.

[0260] That is, all the above-mentioned Physical Uplink Shared Channel (PUSCH) communication methods are applicable to the S-DCI or M-DCI scheduled STxMP transmission mode, which is the SDM transmission mode.

[0261] In some of the Physical Uplink Shared Channel (PUSCH) communication methods disclosed in this disclosure, the terminal supports the SFN transmission mode for PUSCH transmission under STxMP transmission based on S-DCI or M-DCI scheduling.

[0262] That is, the above-mentioned Physical Uplink Shared Channel (PUSCH) communication method is partially applicable to the PUSCH transmission mode under STxMP transmission scheduled by S-DCI or M-DCI, which is the SFN transmission mode.

[0263] In this embodiment of the disclosure, the network device determines that the terminal supports uplink STxMP transmission, and then configures the PUSCH transmission resource configuration parameters. The maximum number of transmission layers, codebook parameters, and SRS resource set of the terminal in PUSCH transmission are configured according to different transmission conditions. This ensures that the terminal can achieve flexibility while enabling PUSCH transmission to support higher transmission rates and throughput.

[0264] Figure 5 This is a flowchart illustrating a Physical Uplink Shared Channel (PUSCH) communication method according to an exemplary embodiment, such as... Figure 5 As shown, the Physical Uplink Shared Channel (PUSCH) communication method used in a terminal includes the following steps.

[0265] In step S21, it is determined that the terminal supports uplink multi-antenna panel simultaneous transmission of STxMP transmission, and the PUSCH transmission resource configuration parameters are configured.

[0266] Among them, the PUSCH transmission resource configuration parameters correspond to the terminal supporting symmetric panel transmission and / or asymmetric panel transmission. The PUSCH transmission resource configuration parameters include at least one of the following: maximum number of transmission data layers, codebook parameters, and SRS resource set configuration parameters.

[0267] The SRS resource set configuration is applied to codebook-based transmissions and / or non-codebook-based transmissions.

[0268] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, a set of symmetric panels or a set of asymmetric panels corresponds to a set of PUSCH transmission resource configuration parameters.

[0269] A set of PUSCH transmission resource configuration parameters may include one or more of the following: maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. For example, a set of PUSCH transmission resource configuration parameters may include the maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. Alternatively, a set of PUSCH transmission resource configuration parameters may include pairwise combinations of the maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. For example, a set of PUSCH transmission resource configuration parameters may include the maximum number of data transmission layers and codebook parameters, or the maximum number of data transmission layers and SRS resource set configuration parameters, or the codebook parameters and SRS resource set configuration parameters. Or, a set of PUSCH transmission resource configuration parameters may include one of the following: the maximum number of data transmission layers, codebook parameters, and SRS resource set configuration parameters. For example, a set of PUSCH transmission resource configuration parameters may include the maximum number of data transmission layers, or codebook parameters, or SRS resource set configuration parameters.

[0270] Terminals are typically configured with multiple physical panels, and the capabilities of different panels may be the same or different. For example, panels with different capabilities may have different numbers of SRS ports, and / or support different maximum data transmission layers, and / or correspond to different transmit powers, etc.

[0271] Network devices determine whether a terminal is currently suitable for simultaneous uplink multi-panel transmission. If the terminal is suitable for simultaneous uplink multi-panel transmission and is scheduled for this purpose, the network device will directly or indirectly instruct the relevant transmission. This relevant transmission includes the terminal's specific beamforming information, the number of transmission data layers used, the Demodulation Reference Signal (DMRS) port allocation, and precoded indication information, etc.

[0272] In one example, symmetrical panel transmission refers to transmission based on a group of panels with identical capabilities within a terminal's multi-panel architecture. Specifically, a symmetrical panel can be two panels with the same number of SRS ports, the same maximum data transmission layer count, and the same transmit power.

[0273] In one example, asymmetric panel transmission refers to transmission based on a set of panels with different capabilities among multiple panels in a terminal. Specifically, the asymmetric panels can be two panels with different numbers of SRS ports, and / or different maximum data transmission layers, and / or different transmit powers.

[0274] In this embodiment of the disclosure, when the network device determines that the terminal supports simultaneous transmission of multiple uplink panels, it configures the PUSCH transmission resource configuration parameters corresponding to the symmetric panel and / or asymmetric panel of the terminal, so that the network device instructs the terminal to dynamically switch between M-TRP and S-TRP through the SRS resource indication set, thereby realizing the indication scheme of different precoding indications in different transmission modes.

[0275] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the maximum number of data transmission layers includes the maximum number of transmission layers supported by different panels in symmetric and / or asymmetric panel transmission supported by the terminal.

[0276] In this embodiment of the disclosure, the maximum number of data transmission layers may include a first maximum number of data transmission layers and / or a second maximum number of data transmission layers.

[0277] The first maximum data transmission layer is the maximum number of data layers that the terminal's corresponding panel can use when transmitting data in M-TRP and / or S-TRP transmission states. When the first maximum data transmission layer is the same for different SRS resource sets supported by the terminal, the first maximum data transmission layer can be represented as maxRank. When the first maximum data transmission layer is different for different SRS resource sets supported by the terminal, the first maximum data transmission layer can be represented as maxRank1 and maxRank2, respectively. The second maximum data transmission layer is the maximum number of data layers that the terminal's corresponding panel can use when transmitting data in S-TRP transmission states. When the second maximum data transmission layer is the same for different SRS resource sets supported by the terminal, the second maximum data transmission layer can be represented as maxRank'. When the second maximum data transmission layer number is different for different SRS resource sets in the symmetric panel and / or asymmetric panel supported by the terminal, the second maximum data transmission layer number can be represented as maxRank1' and maxRank2' respectively.

[0278] For ease of description, in the embodiments of this disclosure, the maximum number of data layers that the corresponding panel of the terminal can use when transmitting data in M-TRP and / or S-TRP transmission states is called the first maximum number of data transmission layers, and the maximum number of data layers that the corresponding panel of the terminal can use when transmitting data in S-TRP transmission states is called the second maximum number of data transmission layers.

[0279] Among them, the maximum number of data transmission layers is the first maximum number of data transmission layers.

[0280] The first data transmission layer is the maximum number of data transmission layers supported by the panel corresponding to the terminal's communication based on M-TRP, and is also the maximum number of data transmission layers supported by the panel corresponding to the terminal's communication based on S-TRP.

[0281] In one example, the SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal correspond to the same first maximum data transmission layer.

[0282] Network devices can configure different SRS resource sets associated with different TRP transmission directions, with each panel corresponding to a different SRS resource set. An SRS resource set can include either a first SRS resource set or a second SRS resource set. In one example, the SRI indicator field indicates multiple TRP transmission states and corresponds to different TRPs, such as TRP1 and TRP2. In this case, the first set of PUSCH transmissions is sent to TRP1 (the first SRS resource set), and the second set of PUSCH transmissions is sent to TRP2 (the second SRS resource set). In S-TRP transmission mode, the SRS resource set corresponding to a panel can be either the first or second SRS resource set. In M-TRP transmission mode, the SRS resource set corresponding to a panel can be either the first or second SRS resource set.

[0283] For ease of description, in the embodiments of this disclosure, any two different SRS resource sets among the multiple SRS resource sets corresponding to the panel are referred to as the first SRS resource set and the second SRS resource set.

[0284] In one example, when maxRank = 4, and maxRank = 4 is used in both the first and second SRS resource sets, then in M-TRP transmission state, the first and second SRS resource sets each correspond to 2 data layers, and in S-TRP transmission state, the first and second SRS resource sets each correspond to 4 data layers. When maxRank' = 2, in S-TRP transmission state, the first and second SRS resource sets each correspond to 2 data layers. If maxRank is used in both the first and second SRS resource sets, then in M-TRP transmission state, the first and second SRS resource sets also each correspond to 2 data layers, and maxRank = 4.

[0285] Among them, different SRS resource sets in the symmetric panels supported by the terminal correspond to the same first maximum data transmission layer.

[0286] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer number is used simultaneously for both the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. Additionally, the first transmission data layer number is used for either the first SRS resource set or the second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first SRS resource set and the second SRS resource set correspond to the same first maximum transmission data layer number.

[0287] In this context, different SRS resource sets in the asymmetric panels supported by the terminal correspond to the same first maximum data transmission layer.

[0288] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. Additionally, the first transmission data layer number is used for either the first SRS resource set or the second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first SRS resource set and the second SRS resource set correspond to the same first maximum transmission data layer number.

[0289] In this embodiment of the disclosure, different SRS resource sets of different panels in the asymmetric panel supported by the terminal correspond to different first maximum transmission data layers.

[0290] Different first maximum data transmission layers refer to the different maximum data transmission layers supported by the corresponding panel when the terminal communicates based on M-TRP. Different first maximum data transmission layers are configured independently and used for the first SRS resource set and the second SRS resource set respectively.

[0291] In one example, when two different first maximum data transmission layers are configured independently, namely maxRank1 and maxRank2, maxRank1 is used for the first SRS resource set corresponding to the panel where the terminal communicates based on M-TRP, and maxRank2 is used for the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP.

[0292] The maximum number of data transmission layers is the second maximum number of data transmission layers.

[0293] The second maximum number of data transmission layers is the maximum number of data transmission layers supported by the panel corresponding to the terminal's communication based on S-TRP.

[0294] In the case where the terminal supports symmetrical panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel that the terminal communicates based on M-TRP correspond to the same first maximum transmission data layer number, and the first SRS resource set or the second SRS resource set corresponding to the panel that the terminal communicates based on S-TRP correspond to the second maximum transmission data layer number.

[0295] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP. The second transmission data layer number is used for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP correspond to the same first maximum transmission data layer number, and the first or second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP corresponds to the second maximum transmission data layer number. The first maximum transmission data layer number is different from the second maximum transmission data layer number.

[0296] In the case where the terminal supports asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP correspond to the same first maximum transmission data layer number, and the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP correspond to the second maximum transmission data layer number.

[0297] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP. The second transmission data layer number is used for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP. That is, the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP correspond to the same first maximum transmission data layer number, and the first or second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP corresponds to the second maximum transmission data layer number. The first maximum transmission data layer number is different from the second maximum transmission data layer number.

[0298] In cases where the terminal supports asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP correspond to different first maximum transmission data layers. Conversely, for panels used for communication based on S-TRP, the first SRS resource set or the second SRS resource set corresponding to the panel corresponds to the same second maximum transmission data layer.

[0299] In this embodiment of the disclosure, the same second maximum data transmission layer number may include maxRank from capability reporting.

[0300] In one example, when two different first maximum transmission data layers are independently configured, such as maxRank1 and maxRank2, maxRank1 and maxRank2 are used respectively for the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. The first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP corresponds to the maxRank from the capability reporting.

[0301] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, different SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal correspond to different second maximum transmission data layers.

[0302] Where the terminal supports symmetric panel and / or asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel communicating based on M-TRP correspond to the same first maximum transmission data layer number. Conversely, for panels communicating based on S-TRP, the first SRS resource set or the second SRS resource set corresponding to the panel corresponds to different second maximum transmission data layers.

[0303] In this embodiment of the disclosure, the different second maximum data transmission layer numbers may include maxRank1' and maxRank2' from capability reporting.

[0304] In one example, when the same first maximum data transmission layer is configured independently, it can be maxRank. maxRank is used simultaneously for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP. maxRank1' or maxRank2' from capability reporting is used for the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, respectively.

[0305] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the SRS resource sets of different panels in the asymmetric panels supported by the terminal correspond to different second maximum transmission data layers.

[0306] In cases where the terminal supports asymmetric panel transmission, the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP correspond to different first maximum transmission data layers. Similarly, for panels used for communication based on S-TRP, the first SRS resource set or the second SRS resource set corresponding to the panel corresponds to different second maximum transmission data layers.

[0307] In this embodiment of the disclosure, the different second maximum data transmission layer numbers may include maxRank1' and maxRank2' from capability reporting.

[0308] In one example, when two different first maximum transmission data layers are independently configured, such as maxRank1 and maxRank2, maxRank1 and maxRank2 are used respectively for the first SRS resource set and the second SRS resource set corresponding to the panel where the terminal communicates based on M-TRP. The maxRank1' or maxRank2' from capability reporting is used respectively for the first SRS resource set or the second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP.

[0309] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the codebook parameters include at least one of the following: codebook subset and full power mode.

[0310] In this embodiment of the disclosure, different panels in a symmetric panel supported by the terminal correspond to the same subset of the codebook and / or the same full-power mode. Alternatively, different panels in asymmetric panels supported by the terminal correspond to the same subset of the codebook and / or the same full-power mode. Alternatively, different panels in asymmetric panels supported by the terminal correspond to different subsets of the codebook and / or different full-power modes.

[0311] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for M-TRP-based communication, and also for either the first or second SRS resource set corresponding to the panel used for S-TRP-based communication. Different panels within the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode.

[0312] For example, if the terminal supports symmetrical panel transmission, and the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panels communicating based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank. maxRank is used simultaneously for the first and second SRS resource sets corresponding to the panels communicating based on S-TRP and / or M-TRP. In this case, different panels in the symmetrical panel are configured with the same codebook subset and / or the same full-power mode.

[0313] In one example, when the terminal supports symmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP, and the second maximum transmission data layer number is used for either the first or second SRS resource set corresponding to the panel used for communication based on S-TRP. Different panels within the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode.

[0314] For example, if the terminal supports symmetrical panel transmission, the first maximum transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP. The second maximum transmission data layer is used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to `maxRank`, and the second maximum transmission data layer corresponds to `maxRank'`. `maxRank` is used for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, and `maxRank'` is used for both the first and second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in the symmetrical panel are configured with the same codebook subset and / or the same full-power mode.

[0315] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for M-TRP-based communication, and also for either the first or second SRS resource set corresponding to the panel used for S-TRP-based communication. Different panels in the symmetric panels supported by the terminal may correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal may correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal may correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal may correspond to different codebook subsets and the same full-power mode.

[0316] For example, if the terminal supports asymmetric panel transmission, and the first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panels communicating based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank. maxRank is used simultaneously for the first and second SRS resource sets corresponding to the panels communicating based on S-TRP and / or M-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0317] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP, and the second maximum transmission data layer number is used for either the first or second SRS resource set corresponding to the panel used for communication based on S-TRP. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0318] For example, if the terminal supports asymmetric panel transmission, the first maximum transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP. The second maximum transmission data layer is used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to `maxRank`, and the second maximum transmission data layer corresponds to `maxRank'`. `maxRank` is used for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, and `maxRank'` is used for both the first and second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0319] In one example, when the terminal supports asymmetric panel transmission, the first transmission data layer number is used simultaneously for both the first and second SRS resource sets corresponding to the panel used for M-TRP-based communication by the terminal, and different second maximum transmission data layers are used for either the first or second SRS resource sets corresponding to the panel used for S-TRP-based communication by the terminal. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0320] For example, the terminal supports asymmetric panel transmission. The first transmission data layer is used simultaneously for both the first and second SRS resource sets corresponding to the panel communicating based on M-TRP. Different independently configured second maximum transmission data layers are used respectively for the first or second SRS resource sets corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to `maxRank`, and the second maximum transmission data layer corresponds to `maxRank1'` or `maxRank2'`. `maxRank` is used simultaneously for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, and `maxRank1'` / `maxRank2'` are used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0321] In one example, when the terminal supports asymmetric panel transmission, different first maximum transmission data layers are used for the first and second SRS resource sets corresponding to the panels used for communication based on M-TRP, respectively, and the second maximum transmission data layer is used for the first or second SRS resource sets corresponding to the panels used for communication based on S-TRP. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0322] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. The second maximum transmission data layer from capability reporting is simultaneously used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to maxRank1 or maxRank2, and the second maximum transmission data layer corresponds to maxRank'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, while maxRank' is used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0323] In one example, when the terminal supports asymmetric panel transmission, different first maximum transmission data layers are used for the first and second SRS resource sets corresponding to the panels used for communication based on M-TRP, respectively, and different second maximum transmission data layers are used for the first or second SRS resource sets corresponding to the panels used for communication based on S-TRP. Different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and the same full-power mode, or different panels in the symmetric panels supported by the terminal correspond to the same codebook subset and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and different full-power modes, or different panels in the symmetric panels supported by the terminal correspond to different codebook subsets and the same full-power mode.

[0324] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. Different second maximum transmission data layers reported by the terminal are used for the first or second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. The first maximum transmission data layers correspond to maxRank1 or maxRank2, and the second maximum transmission data layers correspond to maxRank1' or maxRank2'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, and maxRank1' and maxRank2' are used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. In this case, different panels in a symmetric panel are configured with the same / different codebook subsets and / or the same / different full-power modes.

[0325] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the SRS resource set configuration parameters include at least one of the following: the number of SRS resources in the SRS resource set and the number of ports for each SRS resource in the SRS resource set.

[0326] The SRS resource set configuration parameters can include either the number of SRS resources in the RS resource set or the number of ports for each SRS resource in the RS resource set, or they can include the number of SRS resources in the RS resource set and the number of ports for each SRS resource in the RS resource set.

[0327] In this embodiment of the disclosure, in response to the terminal using codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal is the same, and the number of ports for the SRS resources is the same. And / or in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric and / or asymmetric panels supported by the terminal is the same.

[0328] The network device responds to the terminal by using codebook transmission. The configuration parameters of the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources and the number of ports of the SRS resources. The number of SRS resources and the number of ports of the SRS resources are the same.

[0329] In one example, in response to the terminal using codebook transmission, for an asymmetric panel with 2 antennas and 4 antennas, the number of ports for the SRS resources of both panels can only be configured according to the panel with the lower capability. That is, the number of ports for the SRS resources corresponding to the 4-antenna panel is configured according to the number of ports for the SRS resources of the 2-antenna panel, with the same number of ports (2).

[0330] The network device responds to the terminal by using codebook transmission. The configuration parameters of the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources and the number of ports of the SRS resources. The number of SRS resources and the number of ports of the SRS resources are the same.

[0331] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission, and the number of ports of SRS resources in different SRS resource sets of different panels supported by the terminal is the first maximum number of transmission data layers.

[0332] In one example, in response to the terminal using codebook transmission, the number of SRS resources and the number of ports for the SRS resources are the same in different SRS resource sets of different panels supported by the terminal. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and also for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of ports for the SRS resources is configured as the first maximum transmission data layer.

[0333] For example, in response to the terminal using codebook transmission, the terminal supports symmetric panel transmission, and when the first transmission data layer is configured to be used for both the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank, and the number of ports configured for SRS resources is maxRank.

[0334] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission, and the number of ports of SRS resources in different SRS resource sets of different panels supported by the terminal is the first maximum number of data transmission layers and / or the second maximum number of transmission layers.

[0335] In one example, in response to the terminal using codebook transmission, the number of SRS resources and the number of ports of the SRS resources are the same in different SRS resource sets of different panels supported by the terminal. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of ports of the SRS resources is configured as the first maximum transmission data layer and / or the second maximum transmission data layer. For example, the number of ports of all SRS resources in different SRS resource sets can be configured as the first maximum transmission data layer. Alternatively, the number of ports of all SRS resources in different SRS resource sets can be configured as the second maximum transmission data layer. Or, different SRS resource sets may include both the number of ports of SRS resources configured as the first maximum transmission data layer and the number of ports of SRS resources configured as the second maximum transmission data layer.

[0336] For example, in response to the terminal using codebook transmission, the terminal supports symmetric panel transmission. The first transmission data layer is configured to be used for the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP. The second maximum transmission data layer is configured to be used for the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP. The first maximum transmission data layer corresponds to maxRank, and the second maximum transmission data layer corresponds to maxRank'. At this time, the number of ports configured for SRS resources is maxRank and / or maxRank'.

[0337] The different SRS resource sets include both the number of ports of SRS resources configured for the first maximum data transmission layer and the number of ports of SRS resources configured for the second maximum data transmission layer. For example, in the case of a symmetrical panel with 4 antennas + 4 antennas, if the first maximum data transmission layer is 2 and the second maximum data transmission layer is 4, then the SRS resource set contains one or more SRS resources with 4 ports and one or more SRS resources with 2 ports. In this case, the terminal, in actual application, autonomously selects the corresponding SRS resource for transmission based on either M-TRP or S-TRP transmission.

[0338] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission, the terminal's full power mode is configured as full power mode 2, and the maximum number of SRS resources in the SRS resource set of different panels in the symmetrical panel supported by the terminal is 4.

[0339] If the network device responds to the terminal's full-power mode not being configured as full-power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 2. Alternatively, if the network device responds to the terminal's full-power mode not being configured as full-power mode 2, the maximum number of SRS resources in the different SRS resource sets of different panels in the symmetrical panel supported by the terminal is either the first maximum number of data transmission layers or the second maximum number of transmission layers.

[0340] In one example, in response to the terminal using codebook transmission, when the first maximum transmission data layer is configured to be used simultaneously for the first and second SRS resource sets corresponding to the panel for terminal communication based on M-TRP, and also for the first or second SRS resource set corresponding to the panel for terminal communication based on S-TRP: If the terminal's full power mode is configured as full power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 4. If the terminal's full power mode is not configured as full power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 2.

[0341] In one example, in response to the terminal using codebook transmission, when the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP, the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel used for communication based on S-TRP. If the terminal's full-power mode is configured as full-power mode 2, the maximum number of SRS resources in the SRS resource sets of different panels in the symmetrical panel supported by the terminal is 4. If the terminal's full-power mode is not configured as full-power mode 2, the maximum number of SRS resources in different SRS resource sets of different panels in the symmetrical panel supported by the terminal can be either the first maximum transmission data layer or the second maximum transmission data layer, and either the first or second maximum transmission data layer can be greater than 2.

[0342] When a network device responds to a terminal using non-codebook transmission, the configuration parameters for the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources, and the number of SRS resources is the same.

[0343] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses non-codebook transmission, and the number of SRS resources in different SRS resource sets of different panels in the symmetrical panel supported by the terminal is the first maximum number of transmission data layers.

[0344] In one example, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric panels supported by the terminal is the same. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and also for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of SRS resources configured is the first maximum transmission data layer.

[0345] For example, in response to the terminal using non-codebook transmission, the terminal supports symmetric panel transmission, and when the first transmission data layer is configured to be used for both the first SRS resource set and the second SRS resource set corresponding to the panel used for communication based on M-TRP and / or S-TRP, the first maximum transmission data layer corresponds to maxRank, and the number of ports configured for SRS resources is maxRank.

[0346] In a Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses non-codebook transmission, and the number of SRS resources in different SRS resource sets of different panels in the symmetrical panel supported by the terminal is either the first maximum number of data transmission layers or the second maximum number of transmission layers.

[0347] In one example, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the symmetric panel supported by the terminal is the same. When the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel where the terminal communicates based on M-TRP, and the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel where the terminal communicates based on S-TRP, then the number of SRS resources is configured as the first maximum transmission data layer and / or the second maximum transmission data layer. For example, the number of SRS resources in all different SRS resource sets can be configured as the first maximum transmission data layer. Alternatively, the number of SRS resources in all different SRS resource sets can be configured as the second maximum transmission data layer.

[0348] For example, in response to the terminal using non-codebook transmission, the terminal supports symmetric panel transmission. The first transmission data layer is configured to be used for the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP. The second maximum transmission data layer is configured to be used for the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP. The first maximum transmission data layer corresponds to maxRank, and the second maximum transmission data layer corresponds to maxRank'. At this time, the number of ports configured for SRS resources is maxRank and / or maxRank'.

[0349] The network device responds to the terminal by transmitting codebooks. The configuration parameters of the SRS resource sets corresponding to different SRS resource sets in different panels supported by the terminal include the number of SRS resources and the number of ports of the SRS resources.

[0350] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this embodiment, the terminal uses codebook transmission. Different panels in the asymmetric panels supported by the terminal adopt different full-power configuration modes. The number of SRS resources in the different SRS resource sets corresponding to different full-power configuration modes is different, and the number of ports of the SRS resources is different.

[0351] In one example, when the first maximum transmission data layer is configured for both the first and second SRS resource sets corresponding to the panel used for terminal communication based on M-TRP, and the second maximum transmission data layer is configured for either the first or second SRS resource set corresponding to the panel used for terminal communication based on S-TRP, different panels in the asymmetric panels supported by the terminal adopt different full-power configuration modes. The number of SRS resources in the SRS resource sets corresponding to different panels is different, and the number of ports for the SRS resources is also different.

[0352] For example, in response to the terminal using codebook transmission, the terminal supports asymmetric panel transmission. The first transmission data layer is configured for the first SRS resource set and the second SRS resource set corresponding to the panel for communication based on M-TRP. The second maximum transmission data layer is configured for the first SRS resource set or the second SRS resource set corresponding to the panel for communication based on S-TRP. The first maximum transmission data layer corresponds to maxRank, and the second maximum transmission data layer corresponds to maxRank'. At this time, it is considered that different panels in the asymmetric panels supported by the terminal adopt different full-power configuration modes, the number of SRS resources in the SRS resource set corresponding to different panels is different, and the number of ports of the SRS resources is different.

[0353] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the terminal uses codebook transmission. In different SRS resource sets of different panels supported by the terminal, the number of SRS resources is the same, but the number of ports for the SRS resources is different. And / or, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same.

[0354] In one example, different first maximum transmission data layers are configured for the first and second SRS resource sets corresponding to the panel used for communication based on M-TRP by the terminal, respectively. A second maximum transmission data layer for acquiring capability reporting is configured for the first or second SRS resource set corresponding to the panel used for communication based on S-TRP by the terminal. In response to the terminal using codebook transmission, the network device uses codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same, and the number of ports for the SRS resources is different. Alternatively, the network device uses non-codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same. Or, the network device uses codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same, and the number of ports for the SRS resources is different. Furthermore, the network device also uses non-codebook transmission, where the number of SRS resources in different SRS resource sets of different panels supported by the terminal is the same.

[0355] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. The second maximum transmission data layer from capability reporting is simultaneously used for either the first or second SRS resource set corresponding to the panel communicating based on S-TRP. The first maximum transmission data layer corresponds to maxRank1 or maxRank2, and the second maximum transmission data layer corresponds to maxRank'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, and maxRank' is used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP. In response to the terminal using codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the asymmetric panels supported by the terminal is the same, and the number of ports for the SRS resources is different. And / or in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the asymmetric panels supported by the terminal is the same.

[0356] In the Physical Uplink Shared Channel (PUSCH) communication method provided in this disclosure, the terminal uses codebook transmission. The number of SRS resources and the number of ports for different SRS resources differ in different SRS resource sets of different panels within the asymmetric panels supported by the terminal. And / or, in response to the terminal using non-codebook transmission, the number of SRS resources differs in different SRS resource sets of different panels within the asymmetric panels supported by the terminal.

[0357] In one example, different first maximum transmission data layers are configured for the first and second SRS resource sets corresponding to the panels used for terminal communication based on M-TRP, respectively. Similarly, different second maximum transmission data layers are configured for the first or second SRS resource sets corresponding to the panels used for terminal communication based on S-TRP, respectively. In response to the terminal using codebook transmission, the network device employs different numbers of SRS resources and different numbers of ports for the SRS resources in different SRS resource sets of different panels supported by the terminal. Alternatively, the network device may employ non-codebook transmission, resulting in different numbers of SRS resources in different SRS resource sets of different panels supported by the terminal. Or, the network device may also employ non-codebook transmission, resulting in different numbers of SRS resources in different SRS resource sets of different panels supported by the terminal. Furthermore, the network device may also employ non-codebook transmission, resulting in different numbers of SRS resources in different SRS resource sets of different panels supported by the terminal.

[0358] For example, the terminal supports asymmetric panel transmission. Different independently configured first transmission data layers are used for the first and second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively. Different reported second maximum transmission data layers are used for the first or second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. The first maximum transmission data layers correspond to maxRank1 or maxRank2, and the second maximum transmission data layers correspond to maxRank1' or maxRank2'. maxRank1 and maxRank2 are used for the first / second SRS resource sets corresponding to the panel communicating based on M-TRP, respectively, and maxRank1' and maxRank2' are used for the first / second SRS resource sets corresponding to the panel communicating based on S-TRP, respectively. In response to the terminal using codebook transmission, the number of SRS resources and the number of ports for the SRS resources differ in different SRS resource sets of different panels in the asymmetric panel supported by the terminal. Alternatively, the network device responds to the terminal by using non-codebook transmission, in which case the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is different. Or, the network device responds to the terminal by using codebook transmission, in which case the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is different, and the number of ports for the SRS resources is different, and the network device also responds to the terminal by using non-codebook transmission, in which case the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is different.

[0360] In one example, in response to a terminal using codebook transmission, the number of SRS resources and / or the number of ports of the SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal are determined based on a first maximum data transmission layer or a second maximum data transmission layer.

[0361] In one example, in response to the terminal using non-codebook transmission, the number of SRS resources in different SRS resource sets of different panels in the asymmetric panel supported by the terminal is determined based on a first maximum number of transmission data layers or a second maximum number of transmission layers.
