[0110] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0111] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0112] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only.

[0113] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0114] With the development of communication technology, to ensure coverage, when network equipment (such as base stations) has multiple transmission reception points (TRPs), multiple TRPs (Multi-TRPs) or multiple antenna panels can be used to provide services to terminals. In addition, to provide more balanced service quality within the service area, Coordinated Multiple Point transmission (CoMP) technology has been introduced.

[0115] In a CoMP scenario, the antenna array of each TRP can be divided into several relatively independent panels, allowing the overall array configuration and port count to be flexibly adjusted based on deployment scenarios and service requirements. Panels or TRPs can also be connected by optical fiber, enabling more flexible distributed deployment. In the millimeter wave band, as wavelength decreases, the blocking effect caused by obstacles such as people or vehicles becomes more significant. In this case, to ensure link robustness, collaboration between multiple TRPs or panels can be leveraged to transmit / receive from multiple beams at multiple angles, thereby mitigating the adverse effects of blocking effects.

[0116] For the uplink, the physical uplink shared channel (PUSCH) for different TRPs may actually pass through channels with very different spatial characteristics. Therefore, it is considered that the Quasi Co-Loacted (QCL) type D of the PUSCH channel in different sending directions is different.

[0117] For the convenience of explanation, the QCL-Tyep indicated by TCI-State below is type D.

[0118] The above implementation scheme does not take into account the M-TRP scenario, and the uplink is a single TRP (Single-TRP, S-TRP) transmission. Certain embodiments of the present disclosure enhance the M-TRP uplink transmission under a single downlink control information (Single-Downlink Control Information, S-DCI), and the uplink PUSCH transmission is transmitted in the TRP direction of multiple network devices, and the collaborative transmission under the time division multiplexing (Time Division Multiplexing, TDM) transmission mode is standardized. The PUSCH is repeatedly sent to different TRPs of the network device through different transmission opportunities (Transmission Occasion, TO) in the time domain. This method has relatively low requirements on the terminal capability. Each TO only needs to send PUSCH to one TRP, so it is not required to support the ability to send beams simultaneously, and the transmission delay is relatively large.

[0119] In certain embodiments of the present disclosure, it is desired to transmit data to multiple TRPs simultaneously through multiple panels to increase the reliability and throughput of the transmission, and effectively reduce the transmission delay under multiple TRPs, but the terminal is required to have the ability to send multiple beams simultaneously. The transmission of PUSCH can be based on a single physical downlink control channel (Physical Downlink Control Channel, PDCCH), that is, multiple panels or multiple TRPs scheduled by S-DCI, as shown in Figure 1B. Among them, the terminal communicates with TPR1 of the network device through panel1, for example, receives the first precoding indication information (Transmit Precoding Matrix Indicator, TPMI) TPMI1 sent by TPR1, and sends one or more information related to the transport layer to TRP1, and communicates with TPR2 of the network device through panel2, for example, receives the second precoding indication information TPMI2 sent by TPR2, and sends one or more information related to the transport layer to TRP2. It can also be based on multiple panels or multiple TRPs scheduled by different PDCCHs, that is, multiple downlink control information (Multiple-Downlink Control Information, M-DCI), as shown in Figure 1C. Among them, the terminal communicates with TPR1 of the network device through panel1, for example, receives PDCCH1 sent by TRP1 and sends PUSCH1 to TRP1, and communicates with TPR2 of the network device through panel2, for example, receives PDCCH2 sent by TRP2 and sends PUSCH2 to TRP2.

[0120] Terminals are typically configured with multiple panels, and different panels may have different capabilities. For example, they may have different numbers of Sounding Reference Signal (SRS) ports and support different maximum data transmission layers. For example, one panel may support up to 2 layers, while another may support up to 4 layers. The network scheduler will determine whether the terminal is currently suitable for simultaneous uplink transmission of multiple panels. If the terminal is currently suitable for simultaneous uplink transmission of multiple panels and is scheduled, the network equipment will directly or indirectly indicate the relevant transmission parameters, including terminal-specific beam indication information, the number of data layers used for transmission, the allocation of demodulation reference signal (DMRS) ports used, and precoding indication information.

[0121] In certain embodiments of the present disclosure, the transmission schemes supported by uplink simultaneous transmission from multiple panels (STxMP) for PUSCH based on S-DCI include space division multiplexing (SDM) and single frequency network (SFN). The SDM scheme refers to that different parts of a transport block (TB) of PUSCH are respectively transmitted on the same time-frequency resources to two different TRPs through their respective corresponding DMRS ports or port combinations allocated on different panels, and different panels or different TRPs or different TOs are respectively associated with different TCI states, i.e. beams. The SFN scheme refers to that a TB of PUSCH is respectively transmitted on the same time-frequency resources to two different TRPs through the same DMRS ports or port combinations allocated on different panels, and different panels or different TRPs or different TOs are respectively associated with different TCI states, i.e. beams.

[0122] In some embodiments of the present disclosure, PUSCH uplink transmissions between a network device and a terminal include codebook-based and non-codebook-based uplink transmissions. The transmission scheme is generally selected based on whether reciprocity between the uplink and downlink channels holds. Regardless of the precoding mode, the terminal is required to transmit an SRS, allowing the network device to estimate uplink channel state information (CSI) based on the SRS.

[0123] In some embodiments of the present disclosure, in a non-codebook-based PUSCH transmission, the terminal sends a maximum number of SRS resources that can be transmitted simultaneously to the network device. Assuming that the network device performs an SRI indication to the terminal in time slot n, the corresponding SRS resource transmission is the most recent SRS transmission before time slot n. The terminal determines the limit of the precoding indication based on the maxRank in the high-level parameter PUSCH-Config, and the number of SRS resources indicated by the SRI is not greater than the maxRank. The network device can configure an associated CSI-RS resource for channel measurement for the SRS resource set used for non-codebook uplink transmission. The terminal obtains the precoding of the SRS transmission of the SRS resource set used for non-codebook uplink transmission based on the associated CSI-RS resource.

[0124] For non-codebook-based uplink transmission, in actual systems, it is generally necessary to measure the downlink CSI-RS configured. The terminal utilizes uplink and downlink reciprocity to obtain uplink channel information by measuring the downlink signal. The main process includes: the network configures the downlink CSI-RS associated with non-codebook-based transmission for the terminal to detect the downlink channel; the terminal selects the precoding matrix through downlink channel calculation and transmits the SRS in each precoding beam direction on the configured SRS resource set; the base station performs uplink channel detection on the SRS, and the network simultaneously schedules resources for the UE and notifies the UE via downlink signaling, selecting the beam in the precoding matrix through the SRI indicator; the terminal uses the modified precoding matrix to determine the actual precoding and the number of allowed layers to transmit the PUSCH; the terminal determines the precoding indicator limit based on the high-level parameter maxRank; the number of SRS resources indicated by the SRI is no greater than maxRank. To enable the network to modify the precoding matrix actually used by the terminal, for non-codebook-based transmission, the network needs to configure an SRS resource set for the terminal.

[0125] For non-codebook transmission schemes, the network device can configure one SRS resource set for the terminal, which includes 1 to 4 SRS resources, and each SRS resource includes one SRS port. When the network device configures multiple SRS resources for the terminal for non-codebook uplink transmission, the multiple SRS resources have the same time domain type, that is, all SRS resources are periodic SRS or semi-persistent SRS or non-periodic SRS. The network device can indicate to the terminal through SRI that one or more SRS resources are used for PUSCH precoding determination, and the number of SRS resources corresponding to SRI is the number of streams transmitted by PUSCH. When the network device configures only one SRS resource for non-codebook uplink transmission for the terminal, the SRI field is not included in the DCI used for uplink authorization.

[0126] The SRI indication field for non-codebook transmission is shown in Table 1, where the transmission layer limit Lmax configured by the network device is 4. The terminal determines the corresponding SRI table and the number of bits of the SRI indication field based on this parameter configuration.

[0127] Table 1

[0128] For uplink synchronous transmission of multiple panels, the coordinated transmission scheduling of a TB (Transport Block) of PUSCH based on a single DCI includes multiple different transmission schemes. Each transmission scheme is briefly described below.

[0129] One solution is SDM (Space Division Multiplexing): a PUSCH TB is transmitted on the same time-frequency resource to two different TRPs using DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission opportunities (TO) are associated with different TCI (transmission configuration indicator) states, or beams. Based on this, SDM is further categorized into two types: SDM-A and SDM-B. In SDM-A, different portions of a PUSCH TB are transmitted on the same time-frequency resource to two different TRPs using DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission opportunities (TO) are associated with different TCI states, or beams. In SDM-B, repetitions of the same PUSCH TB corresponding to different RV versions are transmitted on the same time-frequency resource to two different TRPs using DMRS ports or port combinations allocated on different panels. Different panels / TRPs / transmission opportunities (TO) are associated with different TCI states, or beams.

[0130] One solution is the SFN (Single Frequency Network) multiplexing solution: a TB of PUSCH is sent on the same time-frequency resources to two different TRPs through the same DMRS port or port combination allocated on different panels, and different Panes / TRPs / transmission opportunities TO are associated with different TCIstates or beams.

[0131] For simultaneous uplink PUSCH transmission based on multiple panels of a terminal, one or more of the above solutions may be supported.

[0132] In non-codebook and codebook-based M-TRP transmission, the SRI field in the DCI indicates the SRS resources in the SRS resource set. Since R17 supports two SRS resource sets, in non-codebook-based M-TRP PUSCH repeated transmission, the DCI format 0_1 / 0_2 contains two SRI fields associated with the two SRS resource sets. Each SRI field indicates SRI for one TRP. The design of the first SRI field is based on the R15 / 16 framework, and all repeated transmissions use the same number of layers.

[0133] For non-codebook-based transmission, the first SRI field is used to determine the elements in the second SRI field, and the second SRI field only contains the SRI combinations associated with the number of layers indicated by the first SRI field. The number of bits N2 in the second SRI field is determined by the maximum number of codepoints per transmission layer across all transmission layers associated with the first SRI field.

[0134] In codebook-based M-TRP PUSCH repetitive transmissions, two TPMI fields are indicated in DCI formats 0_1 / 0_2. The first TPMI field is designed identically to the TPMI field in R15 / 16 (including the TPMI index and number of layers). The second TPMI field contains only the second TPMI index, and the number of layers is the same as the number of layers indicated in the first TPMI field. The first TPMI field is used to determine the elements in the second TPMI field, and the second TPMI field contains only the TPMI associated with the number of layers indicated in the first TPMI field. The number of bits, M2, in the second TPMI field is determined by the maximum number of codepoints per rank among all ranks associated with the first TPMI field.

[0135] The indication fields for dynamically indicating S-TRP and M-TRP transmission scheduling are shown in Table 2. In S-TRP, the first SRI / TPMI field can be associated with any SRS resource.

[0136] Table 2

[0137] In some embodiments of the present disclosure, the PUSCH transmission of STxMP will configure different SRS resource sets for PUSCH transmission in different TRP / panel / TCI states, with a total of two SRS resource sets configured. For the SDM mode of STxMP transmission, the terminal implementation can consider one of the following two implementations:

[0138] Method 1: Shared digital ports

[0139] Shared digital ports mean that the terminal's baseband digital ports are shared among various panels, that is, the number of baseband transmit links of the terminal is less than or equal to the total number of antenna ports of the panel. The baseband transmit link and both panels can be connected and transmitted on different panels dynamically according to each scheduling; the number of baseband transmit links corresponds to the total number of PUSCH ports. For the implementation of 4T+4T, the terminal can implement up to 4 transmit links to support the transmission requirements under S-TRP and M-TRP. As shown in Figure 1D, under S-TRP transmission, the terminal's four baseband digital ports are associated with the antenna ports of panel 0. As shown in Figure 1E, in the M-TRP transmission scenario, the terminal's two baseband digital ports are associated with the two antenna ports of panel 0, and the terminal's two baseband digital ports are associated with the two antenna ports of panel 1.

[0140] Method 2: Separate digital ports

[0141] Independent digital ports mean that the baseband digital ports are not shared between panels. That is, each baseband transmission link of the terminal has a fixed physical connection with different panels.

[0142] In some embodiments, the discussion of STxMP transmission supports PUSCH M-DCI-based SDM / SFN transmission. Considering differences in terminal processing and implementation, two terminal implementation structures are currently under consideration: separate and shared digital ports. However, there is no consensus on the implementation method for shared digital ports.

[0143] Furthermore, when the terminal supports the shared digital ports mode under the STxMP transmission scheme, how to perform non-codebook PUSCH transmission.

[0144] Based on this, an embodiment of the present disclosure provides a method for transmitting PUSCH. When the terminal supports the STxMP transmission scheme based on the shared digital port mode (hereinafter referred to as the first mode), the network device configures an SRS resource set for the terminal for non-codebook transmission, so that the terminal performs non-codebook transmission based on the configured SRS resource set, thereby realizing PUSCH transmission while saving terminal costs.

[0145] In some embodiments of the present disclosure, terms such as "uplink", "uplink", "physical uplink", etc. can be used interchangeably, and terms such as "downlink", "downlink", "physical downlink", etc. can be used interchangeably.

[0146] In some embodiments of the present disclosure, terms such as "downlink control information (DCI)", "downlink (DL) assignment", "DL DCI", "uplink (UL) grant", and "UL DCI" may be used interchangeably.

[0147] In some embodiments of the present disclosure, terms such as “physical uplink shared channel (PUSCH)” and “UL data” may be used interchangeably.

[0148] It is worth noting that the terminal in the embodiment of the present disclosure supports the shared digital port mode in the STxMP transmission scenario, which will not be further described in the following embodiments of the present disclosure.

[0149] FIG2 is an interactive diagram illustrating a method for transmitting a PUSCH according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for transmitting a PUSCH, the method comprising:

[0150] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0151] In some embodiments, terminal 101 receives first information.

[0152] In some embodiments, the first information is used to configure an SRS resource set for the terminal 101 .

[0153] In some embodiments, the first information is used to configure a non-codebook SRS resource set for the terminal 101. Optionally, the SRS resource set is used for the terminal to perform non-codebook-based physical uplink shared channel (PUSCH) transmission.

[0154] In some embodiments, the first information is used to configure SRS resources for the terminal when the terminal 101 supports the first mode. Optionally, the first mode indicates that the baseband digital port of the terminal is shared among the digital ports of each panel. Optionally, the name of the first mode is not limited and can be, for example, "shared digital port mode" or "shared digital ports mode."

[0155] In some embodiments, the name of the first information is not limited, and it can be, for example, "configuration information", "SRS configuration information", "indication information", etc.

[0156] In some embodiments, the first information is carried in MAC-CE or DCI information or RRC signaling.

[0157] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0158] In some embodiments, the SRS resource set is configured by higher-level parameters, such as higher-level parameters in SRS-config.

[0159] In some embodiments, when configuring the function of the SRS resource set, the network device may configure the function as one or more of codebook, non-codebook, antenna switching, and beam management.

[0160] Optionally, by configuring the high-level parameter "usage" of the SRS resource set to "nonCodebook", an SRS resource set with a non-codebook function is configured.

[0161] In some implementations, when the network device 102 configures the SRS resource set for the terminal 101 through the first information, the following two methods are included:

[0162] Method 1: The PUSCH transmission configuration associated with each panel / TRP / TCI state includes multiple SRS resource sets.

[0163] In some embodiments, the multiple SRS resource sets include SRS resources with different numbers of SRS resources. For example, each PUSCH transmission is configured with two SRS resource sets, one of which includes four SRS resources and the other includes two SRS resources.

[0164] Optionally, each SRS resource set includes multiple single-port SRS resources.

[0165] In some embodiments, among the multiple SRS resource sets corresponding to the PUSCH transmission associated with each panel / TRP / TCI state, different SRS resource sets correspond to different transmission schemes of the terminal. For example, each PUSCH transmission is configured with two SRS resource sets, one of which is used by the terminal for STxMP transmission and one is used by the terminal for S-TRP transmission.

[0166] In some embodiments, the number of SRS resources included in different SRS resource sets is determined based on the maximum number of transmission layers configured for different transmission schemes. For example, if the maximum number of transmission layers configured for STxMP transmission by the terminal is 4, the number of SRS resources included in the SRS resource set corresponding to STxMP transmission is 4.

[0167] In some embodiments, the first information is also used to configure associated CSI-RS resources for multiple SRS resource sets corresponding to PUSCH transmission associated with each panel / TRP / TCI state.

[0168] Optionally, among the multiple SRS resource sets, SRS resource sets corresponding to different transmission schemes are associated with the same or different CSI-RS resources.

[0169] Optionally, the terminal calculates precoding of each SRS resource based on the CSI-RS resource associated with each SRS resource set.

[0170] Method 2: Configure an SRS resource set for PUSCH transmission associated with each panel / TRP / TCI state.

[0171] In some embodiments, an SRS resource set includes multiple SRS resource subsets.

[0172] In some embodiments, different SRS resource subsets among the multiple SRS resource subsets correspond to different transmission schemes of the terminal.

[0173] For example, if the terminal's transmission scheme includes an STxMP transmission scheme and an S-TRP transmission scheme, each SRS resource set includes two SRS resource subsets, one of which is used for the terminal to perform STxMP transmission, and the other is used for the terminal to perform S-TRP transmission.

[0174] In some embodiments, the number of SRS resources included in different SRS resource subsets is determined based on the maximum number of transmission layers configured for different transmission schemes. For example, if the maximum number of transmission layers configured for STxMP transmission by the terminal is 4, the number of SRS resources included in the SRS resource subset corresponding to STxMP transmission is 4.

[0175] In some embodiments, the SRS resources included in the SRS resource set of the plurality of SRS resource subsets are determined based on a preset rule.

[0176] In some embodiments, "specific A", "predetermined A", "preset A", "set A", "indicate A", "certain A", "arbitrary A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or instruction, etc., or as specific A, certain A, arbitrary A, or first A, etc., but not limited to this.

[0177] Optionally, the preset rule is that the first N SRS resources in the SRS resource set are the SRS resource subset corresponding to the first transmission scheme, where N is the maximum number of transmission layers configured for the first transmission scheme; the last M SRS resources in the SRS resource set are the SRS subset corresponding to the second transmission scheme, where M is the maximum number of transmission layers configured for the second transmission scheme.

[0178] For example, if the maximum number of transmission layers configured for S-TRP transmission is 4, then the SRS resource subset used for S-TRP transmission may include the first four SRS resources in the SRS resource set. For another example, if the maximum number of transmission layers configured for STxMP transmission is 2, then the SRS resource subset used for STxMP transmission may include the last two SRS resources in the SRS resource set.

[0179] In some embodiments, the first information is also used to configure associated CSI-RS resources for multiple SRS resource subsets corresponding to PUSCH transmission associated with each panel / TRP / TCI state.

[0180] Optionally, among multiple SRS resource subsets, CSI-RS resources associated with different SRS resource subsets are the same or different.

[0181] Optionally, the terminal calculates precoding of each SRS resource based on the CSI-RS resource associated with each SRS resource subset.

[0182] In some embodiments, when a terminal receives a CSI-RS resource sent by a network device and uses the CSI-RS resource to perform downlink channel measurement, after obtaining the downlink channel measurement result, the terminal can obtain detailed information of the uplink channel.

[0183] Step S2102: Terminal 101 sends SRS resources to network device 102 based on the first information.

[0184] In some embodiments, the terminal 101 sends SRS resources based on the SRS resource set configured by the first information.

[0185] In some embodiments, the terminal 101 precodes the SRS resource based on the SRS resource set configured by the first information, and sends the precoded SRS resource.

[0186] In some embodiments, terminal 101 sends the SRS resource based on the SRS resource index.

[0187] In some embodiments, the terminal 101 first sends the SRS resources corresponding to the S-TRP transmission scheme, and then sends the SRS resources corresponding to the STxMP transmission scheme; or the terminal 101 first sends the SRS resources corresponding to the STxMP transmission scheme, and then sends the SRS resources corresponding to the S-TRP transmission scheme

[0188] In some embodiments, when the terminal sends SRS resources, for S-TRP, each SRS port sends max Rank layer data, and the max Rank layer data corresponds to max Rank SRS ports; for STxMP, the total number of effective SRS ports is equal to the total number of PUSCH ports, that is, each SRS port actually corresponds to 1 PUSCH port, but each SRS port is sent through all physical antennas.

[0189] In some embodiments, the network device 102 may perform uplink channel estimation based on SRS resources.

[0190] Step S2103 , the network device 102 sends second information to the terminal 101 .

[0191] In some embodiments, terminal 101 receives second information.

[0192] In some embodiments, the second information is used to indicate an SRI indication field, and an SRS set resource associated with the SRI indication field is used for the terminal to send a PUSCH.

[0193] In some embodiments, the second information indicates the SRI indication field by indicating a code point. Referring to Table 2, if the code point indicated by the second information is 01, the first SRS resource set associated with the first SRI indication field is used by the terminal to transmit the first PUSCH, and the second SRS resource set associated with the second SRI indication field is used by the terminal to transmit the second PUSCH.

[0194] In some embodiments, the second information is DCI.

[0195] In some embodiments, the name of the second information is not limited, and it can be, for example, "indication information", "SRI indication information", etc.

[0196] In some embodiments, different SRI indication fields are associated with multiple SRS resource sets corresponding to different PUSCH transmissions.

[0197] Optionally, the SRS resource sets indicated by different SRI indication fields are determined based on a transmission scheme of the terminal.

[0198] Optionally, the transmission scheme of the terminal is indicated by an SRS resource set indication field. Optionally, the SRS resource set indication field is carried in a DCI.

[0199] Exemplarily, referring to Table 1, the code point of the SRS resource set indication field is 10, and the transmission scheme of the terminal is the M-TRP transmission scheme.

[0200] Step S2104 , the network device 102 sends third information to the terminal 101 .

[0201] In some embodiments, terminal 101 receives third information.

[0202] In some embodiments, the third information is used to indicate an SRI indication field. Optionally, an SRS resource subset associated with the SRI indication field is used for the terminal to transmit a PUSCH.

[0203] In some embodiments, different SRI indication fields are associated with multiple SRS resource subsets corresponding to different PUSCH transmissions.

[0204] In some embodiments, the SRI indication field indicates the SRS resources corresponding to PUSCH transmissions associated with different panel / TRP / TCI states in at least one of the following ways:

[0205] Based on the SRS resource sets corresponding to different PUSCH transmissions, the SRS resources corresponding to different PUSCH transmissions are indicated;

[0206] Based on the SRS resource sets corresponding to different PUSCH transmissions, the SRS resource subset corresponding to the terminal's transmission scheme indicates the SRS resources corresponding to different PUSCH transmissions;

[0207] Based on the valid SRS resources in the SRS resource subset corresponding to the transmission scheme of the terminal in the SRS resource sets corresponding to different PUSCH transmissions, the SRS resources corresponding to different PUSCH transmissions are indicated.

[0208] Optionally, the SRI indication field indicates the SRS resources corresponding to different PUSCH transmissions based on the SRS resource sets corresponding to different PUSCH transmissions. Optionally, the SRI table needs to be expanded according to the number of SRS resources.

[0209] Taking Table 1 above as an example, the SRI table is based on Nsrs_strp = maxRank corresponding to the configuration of the SRI indication of a maximum of 4 SRS resources. The extended SRI table can be configured according to (maxRank, maxRank') a set of parameters (NSRS_S-TRP , N SRS_M-TRP ), where maxRank corresponds to the maximum number of transmission layers supported under the S-TRP transmission scheme, and maxRank' corresponds to the maximum number of transmission layers supported under the M-TRP transmission scheme. When maxRank under the S-TRP transmission scheme is 4 layers in the shared digital port mode, maxRank' under the M-TRP transmission scheme can be 2 layers, so a maximum of 6 SRS resources can be configured for the SRS resource set associated with each panel / TRP / TCI state of the terminal. Based on this, the SRI table can be expanded to N based on the SRI table in Table 1. SRS =5 / 6 SRI table, used to indicate one or more SRS resources actually used by PUSCH in non-codebook based transmission. For M-TRP transmission scheme, the SRS resource indicated by SRI corresponds to the N-based SRS resource configured for M-TRP transmission scheme. SRS_M-TRP One or more SRS resources in an SRS resource subset of SRS resources.

[0210] Exemplarily, the SRI indication based on non-codebook transmission is shown in Table 3.

[0211] Table 3

[0212] Optionally, the SRI indication field indicates an SRS resource subset corresponding to the terminal's transmission scheme in the SRS resource sets corresponding to different PUSCH transmissions, and the SRS resources corresponding to different PUSCH transmissions are indicated by SRI. Optionally, the terminal's transmission scheme is indicated based on the SRS resource set indication field.

[0213] For example, the maximum number of transmission layers of PUSCH under the S-TRP transmission scheme is 4 in the shared digital port mode, and the SRS resource set subset 1 corresponds to the S-TRP transmission scheme and is configured with 4 SRS resources. When the maximum number of transmission layers under multi-TRP transmission is 2, the SRS resource set subset 2 corresponds to the S-TRP transmission and is configured with 2 SRS resources. Therefore, the SRS resource set associated with each panel / TRP / TCI state of the terminal contains 6 SRS resources. Based on this, the SRI table can be expanded to N based on the SRI table shown in Table 1. SRS =5 / 6 SRI table, which is used to indicate one or more SRS resources actually used by PUSCH in non-codebook based transmission.

[0214] For the S-TRP transmission scheme, the SRS resource indicated by SRI corresponds to the SRS resource configured for the S-TRP transmission scheme. SRS_S-TRPFor the M-TRP transmission scheme, the SRS resource indicated by SRI corresponds to the SRS resource subset containing N SRS resources configured for the M-TRP transmission scheme. SRS_M-TRP One or more SRS resources in an SRS resource subset of an SRS resource. In different transmission schemes, SRI can use the SRI codepoint in the SRI table shown in Table 1 to indicate the SRS resources in the SRS resource subset.

[0215] Optionally, the SRI indication field indicates the SRS resources corresponding to different PUSCH transmissions based on valid SRS resources in the SRS resource subset corresponding to the terminal's transmission scheme in the SRS resource sets corresponding to different PUSCH transmissions. Optionally, the terminal's transmission scheme is indicated based on the SRS resource set indication field.

[0216] For example, the maximum number of transmission layers of PUSCH under the S-TRP transmission scheme is 4 in the shared digital port mode, and the SRS resource set subset 1 corresponds to the S-TRP transmission scheme and is configured with 4 SRS resources. When the maximum number of transmission layers under multi-TRP transmission is 2, the SRS resource set subset 2 corresponds to the S-TRP transmission and is configured with 2 SRS resources. Therefore, the SRS resource set associated with each panel / TRP / TCI state of the terminal contains 6 SRS resources. Based on this, the SRI table can be expanded to N based on the SRI table shown in Table 1. SRS =5 / 6 SRI table, used to indicate one or more SRS resources actually used by PUSCH in non-codebook based transmission. Optionally, the SRI table can refer to Table 3 above.

[0217] For the S-TRP transmission scheme, the SRS resource indicated by SRI corresponds to the SRS resource configured for the S-TRP transmission scheme. SRS_S-TRP One or more SRS resources that are valid SRS resources in the SRS resource subset of the SRS resources. For the M-TRP transmission scheme, the SRS resources indicated by the SRI correspond to the N SRS resources configured for the M-TRP transmission scheme. SRS_M-TRP One or more SRS resources that are valid SRS resources in an SRS resource subset of SRS resources.

[0218] In some embodiments, the SRI indication field indicates SRS resources corresponding to different PUSCH transmissions based on a code point or a bitmap.
