[0060] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communications field, for example, it may be an evolution of an existing LTE protocol, NR protocol, Wi-Fi protocol, or a protocol related to other communication systems. The present application does not limit the protocol type.

[0061] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0062] To facilitate a better understanding of the embodiments of the present application, the multi-beam system related to the present application is described.

[0063] The design goals of NR systems or 5G systems include wide-bandwidth communications in high-frequency bands (e.g., bands above 6 GHz). As the operating frequency increases, the path loss during transmission increases, affecting the coverage capability of the high-frequency system. To effectively ensure the coverage of high-frequency NR systems, an effective technical solution is to use multiple beam (or hybrid beam) technology based on massive antenna arrays (such as Multiple Input Multiple Output (MIMO)) to improve coverage.

[0064] In a typical system, a cell (sector) uses a wide beam to cover the entire cell. Therefore, at every moment, UEs within the cell coverage area have the opportunity to obtain transmission resources allocated by the system.

[0065] NR or 5G multi-beam systems use different beams to cover the entire cell. Each beam covers a smaller area, and multiple beams are scanned over time to achieve full cell coverage. Currently, different beams are identified by the different signals they carry.

[0066] Different synchronization signal blocks (SSBs) are transmitted on different beams, and the UE can distinguish different beams by different SSBs. SSBs are also called synchronization signal / physical broadcast channel blocks (SS / PBCH blocks).

[0067] Different channel state information reference signals (CSI-RS) are transmitted on different beams, and the UE identifies different beams through the CSI-RS signals / CSI-RS resources.

[0068] In a multi-beam system, the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH) can be transmitted through different downlink transmit beams.

[0069] For systems below 6G, there is generally no analog beam on the UE side, so an omnidirectional antenna (or a nearly omnidirectional antenna) is used to receive signals sent by different downlink transmission beams of the base station.

[0070] In millimeter wave systems, the UE may have analog beams, requiring the corresponding downlink receive beam to receive the signal from the corresponding downlink transmit beam. In this case, beam indication information is required to assist the UE in determining the network's transmit beam information or the UE's corresponding receive beam information.

[0071] In the NR protocol, the beam indication information does not directly indicate the beam itself, but is indicated by the quasi-co-located (QCL) quasi-co-located type (such as QCL type D (QCL-TypeD)) between the signals. On the UE side, the determination of receiving the corresponding channel / signal is also based on the QCL quasi-co-located assumption. The QCL quasi-co-located assumption is indicated by the TCI state (TCI-state), that is, the network configures and / or indicates the transmission configuration indicator (TCI) state through relevant signaling (Radio Resource Control (RRC), and / or, Media Access Control Control Element (MAC CE), and / or, Downlink Control Information (DCI)).

[0072] To facilitate a better understanding of the embodiments of the present application, the multi-transmission reception point (TRP) / antenna panel / beam transmission related to the present application is explained.

[0073] Multiple TRP (mTRP or M-TRP) transmission means that multiple TRPs can communicate with a terminal simultaneously on the same carrier. Because in the NR system, multiple TRP transmissions, or multiple panels or multiple beams transmitting to a terminal simultaneously, can use the same solution, they are often not distinguished in the description (for example, referred to as multiple TRP transmission, mTRP transmission, or M-TRP transmission), or are expressed as multiple TRP / panel / beam transmission.

[0074] The solution of transmitting downlink data to the UE simultaneously with multiple TRPs, multiple antenna panels, or multiple beams supports the following two types of solutions:

[0075] Solution 1: Single-PDCCH based scheme. The UE detects only one PDCCH. The DCI detected on this control channel PDCCH indicates relevant information about the data transmitted simultaneously on multiple TRPs / panels / beams (from the protocol level, multiple TRPs / panels / beams are not visible. What is seen is that one transmission requires multiple TCI-states, that is, multiple TCI-states are used to implicitly support multiple TRPs / panels / beam transmissions).

[0076] Solution 2: Multiple-PDCCH based scheme, the UE receives different PDCCHs from different TRPs / panels / beams, and the DCI detected on each control channel PDCCH indicates relevant indication information of a corresponding data transmission (from the protocol level, it is not visible that there are multiple TRPs / panels / beams, but only that the control resource set (CORESET) corresponding to the DCI of the scheduling data may be associated with different CORESET resource pool numbers (CORESET pool index), that is, corresponding to different CORESET resource pool numbers (pool index), that is, multiple TRP / panel / beam transmissions are implicitly supported through multiple different CORESET pool indexes).

[0077] Specifically, multiple TRP transmissions can be shown in Figure 2, and multiple beam transmissions can be shown in Figure 3.

[0078] For solution 1, the UE only needs to detect one PDCCH, so the control channel detection complexity may be lower than that of solution 2. Solution 1 requires fast information exchange between different panels / TRPs / beams.

[0079] For solution 2, the UE needs to detect multiple PDCCHs simultaneously on the same carrier, which may increase the complexity, but may improve flexibility and robustness.

[0080] Scenarios where Option 2 may be applied include at least one of the following:

[0081] S1-1: Multiple TRPs belong to the same cell, and the connectivity (backhaul) between TRPs is ideal (i.e., fast and dynamic information exchange is possible);

[0082] S1-2: Multiple TRPs belong to the same cell, and the connection (backhaul) between TRPs is non-ideal (i.e., TRPs cannot exchange information quickly and can only exchange data relatively slowly);

[0083] S1-3: Multiple TRPs belong to different cells, and the connection (backhaul) between TRPs is ideal;

[0084] S1-4: Multiple TRPs belong to different cells, and the connection (backhaul) between TRPs is non-ideal;

[0085] S2-1, S2-2, S2-3, S2-4: Replace the TRPs above with beams, and you can get four multi-beam application scenarios.

[0086] Solution 1 is generally considered to be only applicable to ideal backhaul scenarios (i.e., S1-1 and S1-3).

[0087] In Release 16 (R16), multiple TRP transmissions for downlink data transmission are supported. In Release 17 (R17), multiple TRP transmissions for the Physical Downlink Control Channel (PDCCH), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH) are supported to increase the reliability of transmissions on the corresponding channels.

[0088] The sounding reference signal (SRS) resources used by PUSCH when transmitting to two TRPs and the precoding matrix used for codebook transmission may be different to match the channel states of different TRPs respectively. Therefore, single DCI scheduling (for PUSCH dynamically scheduled by DCI) supports two SRS resource indicators (SRS resource indicator, SRI) / transmit precoding matrix indication (Transmit Precoding Matrix Indicator, TPMI) indicated by one DCI, that is, based on two independent SRI fields and two independent TPMI fields to indicate the PUSCH corresponding to the two TRPs.

[0089] Different from dynamically scheduled PUSCH (for example, each time PUSCH is dynamically scheduled using DCI), some parameters of configured grant (CG) PUSCH (i.e., no dynamic scheduling is required, no DCI is required for dynamic scheduling) are configured by RRC signaling, rather than dynamically indicated by DCI. NR supports Type 1 CG PUSCH (Type1 CG PUSCH) and Type 2 CG PUSCH (Type2 CG PUSCH). Type 1 CG PUSCH is semi-statically configured by RRC, including time-frequency domain resources, demodulation reference signal (DMRS), open-loop power control, modulation and coding scheme (MCS), and other parameters required for PUSCH transmission. Type 2 CG PUSCH is semi-statically configured by RRC, including the period of time domain resources, power control, number of repetitions, etc., and is activated by DCI, and time-frequency resources, DMRS, MCS and other parameters are indicated in the same DCI. R17 enhances both types of CG PUSCH based on multiple TRPs. R17 specifies adding a set of P0-PUSCH-Alpha and power control loop (powerControlLoopToUse) to the CG configuration (ConfiguredGrantConfig) for power control of the second TRP. For Type 2 CG PUSCH, the original first set of power control values ​​is associated with the first SRS resource set, and the second set of values ​​is associated with the second SRS resource set. The use of the first or second set of power control depends on the newly added 2-bit field in the DCI to indicate the dynamic switching between single TRP and multiple TRPs. For Type 1 CG PUSCH, a set of path loss reference index (pathlossReferenceIndex) field, SRS resource indication (srs-ResourceIndicator) field, and precoding and number of layers (precodingAndNumberOfLayers) field are added to the RRC configuration uplink grant (rrc-ConfiguredUplinkGrant) to indicate the path loss reference signal, SRI and TPMI corresponding to the second TRP.It should be emphasized that, unlike DCI signaling which has high overhead requirements, RRC signaling has relatively low overhead requirements. Therefore, the srs-ResourceIndicator field and precodingAndNumberOfLayers field associated with the second SRS resource set indicated by RRC occupy the same number of bits as the srs-ResourceIndicator field and precodingAndNumberOfLayers field associated with the first SRS resource set.

[0090] It should be noted that configuration grant (CG) can also be called: scheduling-free or dynamic scheduling-free.

[0091] It's important to note that the transmission schemes discussed above for multi-TRP systems are all for the same carrier. For example, in a multiple-PDCCH-based scheme, the terminal detects multiple DCIs (current protocols support two) on the same carrier. Each DCI can schedule a corresponding PDSCH, and multiple PDSCHs are also on the same carrier or in the same cell. The same applies to uplink multi-TRP transmission, which only applies to transmissions on the same carrier.

[0092] To facilitate a better understanding of the embodiments of the present application, the TCI state related to the present application is described.

[0093] To improve reception performance, terminals can leverage the characteristics of the transmission environment to improve their reception algorithms. For example, channel statistics can be leveraged to optimize the design and parameters of the channel estimator. In NR systems, these characteristics of data transmission are represented by Quasi-Co-located (QCL) information (QCL-Info).

[0094] If the downlink transmission comes from different TRP / panel / beam, the characteristics of the transmission environment corresponding to the data transmission may also change. Therefore, in the NR system, when the network side transmits the downlink control channel or data channel, it will indicate the corresponding QCL status information to the terminal through the TCI state.

[0095] A TCI state can contain the following configurations:

[0096] TCI status identifier (Identity, ID), used to identify a TCI status;

[0097] QCL information 1;

[0098] QCL information 2 (optional).

[0099] Among them, a QCL information contains the following information:

[0100] QCL type configuration, which can be one of QCL type A, QCL type B, QCL type C, or QCL type D;

[0101] The QCL reference signal configuration includes the cell ID where the reference signal is located, the bandwidth part (Band Width Part, BWP) ID, and the reference signal identifier (which can be a CSI-RS resource ID or SSB index).

[0102] Among them, if QCL information 1 and QCL information 2 are both configured, the QCL type of at least one QCL information must be one of typeA, typeB, and typeC, and the QCL type of the other QCL information (if configured) must be QCL type D.

[0103] The definitions of different QCL type configurations are as follows:

[0104] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0105] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0106] 'QCL-TypeC': {Doppler shift, average delay};

[0107] 'QCL-TypeD': {Spatial Rx parameter}.

[0108] For example, the semantic fields of the TCI status can be described as follows.

[0109]

[0110] In the NR system, the network side can indicate the corresponding TCI status for the downlink signal or downlink channel.

[0111] If the network side configures the QCL reference signal of the target downlink channel or target downlink signal as a reference SSB or reference CSI-RS resource through the TCI state, and the QCL type is configured as typeA, typeB or typeC, the terminal can assume that the target downlink signal and the reference SSB or reference CSI-RS resource have the same large-scale parameters, which are determined by the QCL type configuration.

[0112] Similarly, if the network side configures the QCL reference signal of the target downlink channel or downlink signal as a reference SSB or reference CSI-RS resource through the TCI state, and the QCL type is configured as typeD, the terminal can use the same receiving beam (ie, Spatial Rx parameter) as that for receiving the reference SSB or reference CSI-RS resource to receive the target downlink signal. Typically, the target downlink channel (or downlink signal) and its reference SSB or reference CSI-RS resource are sent by the same TRP or the same panel or the same beam on the network side. If the transmission TRP or transmission panel or transmission beam of two downlink signals or downlink channels is different, different TCI states are usually configured.

[0113] For the downlink control channel, the TCI status of the corresponding CORESET can be indicated by RRC signaling or RRC signaling + MAC signaling.

[0114] For the downlink data channel, the available TCI state set is indicated by RRC signaling, and some of the TCI states are activated by Media Access Control (MAC) layer signaling. Finally, one or two TCI states are indicated from the activated TCI states through the TCI state indication field in the DCI for the PDSCH scheduled by the DCI. The case of 2 TCI states is mainly for scenarios similar to multiple TRPs. For example, as shown in Figure 4, the network device indicates N candidate TCI states through RRC signaling, activates K TCI states through MAC signaling, and finally indicates 1 or 2 used TCI states from the activated TCI states through the TCI state indication field in the DCI.

[0115] To facilitate a better understanding of the embodiments of the present application, the unified TCI state related to the present application is described.

[0116] The TCI status indication mechanism only applies to downlink channels and signals and has many limitations in NR systems. To provide a more unified uplink and downlink beam management mechanism for NR systems, a unified TCI status concept is proposed. The following are some important new features added:

[0117] Two unified TCI status modes are designed, namely Mode 1 and Mode 2 as follows;

[0118] Downlink channels (partial PDCCH, PDSCH) and signals (aperiodic CSI-RS) use the same downlink transmit indicator beam and use the downlink TCI state or joint TCI state. This type of TCI state is called a separate TCI state.

[0119] Uplink channels (such as PUCCH or PUSCH) and signals (such as SRS) use the same uplink transmit beam and use the uplink TCI state (UL TCI state) or joint TCI state;

[0120] The unified TCI state can be dynamically updated and indicated using MAC CE and / or DCI;

[0121] Applicable to carrier aggregation scenarios, the beam indication on a single component carrier (CC) can be applied to multiple different CCs;

[0122] The uplink beam indication can be given simultaneously with the uplink power control parameters through the UL TCI state or joint TCI state;

[0123] Supports inter-cell beam management function.

[0124] Mode 1: Includes one TCI state, which is applicable to both uplink and downlink channels and signals. This TCI state is called a joint TCI state.

[0125] Mode 2: Contains two types of TCI states, where the DL TCI state applies only to downlink channels and signals; the UL TCI state applies only to uplink channels and signals.

[0126] For each CORESET on CC, it can be roughly divided into the following four types:

[0127] CORESET A: Associated only with the UE-specific search space, it can be considered a UE-specific downlink control channel resource and must follow the indicated unified TCI state.

[0128] CORESET B: Associated only with the cell-common search space. Whether it can follow the unified TCI state indicated by the NW depends on the RRC configuration of the network device.

[0129] CORESET C: Associated with both the UE-specific search space and the cell-common search space. Whether it can follow the unified TCI state indicated by the network device depends on the RRC configuration of the network device.

[0130] CORESET 0: It must be associated with the cell common search space and can also be associated with the UE-specific search space. Whether it can follow the unified TCI state (Unified TCI state) indicated by the network device depends on the RRC configuration of the network device.

[0131] At present, the unified TCI state mechanism does not consider the scenario of multi-TRP transmission, and only supports the scenario of single TRP.

[0132] It should be noted that when referring to TCI state, if the TCI state is not explicitly specified, it includes any of the TCI states mentioned above, that is, the TCI state can be a joint TCI state, a separate TCI state, a DL TCI state, a UL TCI state, or a combination thereof (that is, including multiple different types of TCI states). If the RRC parameter TCI-State is used (there is a hyphen between the two words), it generally refers to the DL TCI state and / or the joint TCI state. If the RRC parameter downlink or joint TCI state (DLorJointTCIState) is used, it generally refers to the DL TCI state and / or the joint TCI state. If the RRC parameter uplink TCI state (UL-TCIState or TCI-UL-State or UL-TCI-State) is used, it generally refers to the uplink TCI state and / or the joint TCI state.

[0133] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0134] There is still a lack of complete solutions and specific details on how to configure and indicate the unified TCI state for PUSCH repetition in a multi-TRP transmission system.

[0135] Based on the above problems, this application proposes a solution for configuring or indicating a unified TCI state, and provides a unified TCI state configuration, indication, and determination solution for the PUSCH transmission scheme in the transmission scenario of multiple transmit and receive points (M-TRP) / antenna panel (panel) / beam (beam).

[0136] The technical solution of this application is described in detail below through specific embodiments.

[0137] FIG5 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG5 , the wireless communication method 200 may include at least part of the following contents:

[0138] S210, the network device sends first indication information, where the first indication information is used to indicate a first SRS resource set and a second SRS resource set, where both the first SRS resource set and the second SRS resource set are used for a codebook-based or non-codebook-based PUSCH; wherein the first SRS resource set is associated with a TCI state among K1 TCI states, and / or the second SRS resource set is associated with a TCI state among K1 TCI states; or, some or all of the two SRS resources indicated by the first indication information are associated with a TCI state among K1 TCI states; wherein the K1 TCI states are currently activated TCI states corresponding to uplink transmission, and K1 is a positive integer;

[0139] S220, the terminal device receives the first indication information.

[0140] In an embodiment of the present application, the first SRS resource set is associated with a TCI state among K1 TCI states, and / or the second SRS resource set is associated with a TCI state among K1 TCI states. That is, the embodiment of the present application clarifies the TCI state associated with the first SRS resource set and / or the second SRS resource set, so that the uplink transmission spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set can be determined based on the first SRS resource set and its associated TCI state, and / or the uplink transmission spatial filter or spatial relationship corresponding to the PUSCH associated with the second SRS resource set can be determined based on the second SRS resource set and its associated TCI state. Alternatively, in an embodiment of the present application, some or all of the two SRS resources are associated with a TCI state among K1 TCI states, that is, the embodiment of the present application clarifies the association relationship between some or all of the two SRS resources and the TCI state, so that the uplink transmission spatial filter or spatial relationship corresponding to the PUSCH associated with the SRS resource can be determined based on the SRS resource and its associated TCI state.

[0141] In the embodiment of the present application, K1 TCI states are currently activated (active or activated) TCI states corresponding to uplink transmission, or it can also be expressed as K1 TCI states are currently used (applied) TCI states corresponding to uplink transmission.

[0142] In some embodiments, for a terminal device, the K1 TCI states are used to determine uplink transmission; for a network device, the K1 TCI states are used to indicate uplink transmission.

[0143] In some embodiments, a TCI state among the K1 TCI states is a joint TCI state, or a TCI state among the K1 TCI states is an uplink TCI state.

[0144] In some embodiments, the TCI state described in the embodiments of the present application is a unified TCI state. Specifically, the network device may indicate, through an indication message, that the type of the unified TCI state is a joint TCI state, i.e., the TCI state among the K1 TCI states is a joint TCI state; or, specifically, the network device may indicate, through an indication message, that the type of the unified TCI state is a separate TCI state, i.e., the TCI state among the K1 TCI states is an uplink TCI state (UL TCI state).

[0145] In some embodiments, the first indication information may be carried by one of the following: RRC signaling, DCI signaling, or MAC CE signaling.

[0146] In some embodiments, the first indication information is used to indicate a first SRS resource set and a second SRS resource set. In other words, the first indication information is used to indicate two SRS resource sets. For example, of the two SRS resource sets, the one with the smaller SRS resource set ID is the first SRS resource set, and the one with the larger SRS resource set ID is the second SRS resource set. For another example, of the two SRS resource sets, the one with the larger SRS resource set ID is the first SRS resource set, and the one with the smaller SRS resource set ID is the second SRS resource set.

[0147] In some embodiments, the first SRS resource set and the second SRS resource set are both used for codebook-based or non-codebook PUSCH. In other words, the usage of the two SRS resource sets indicated by the first indication information is for codebook-based PUSCH, or the usage of the two SRS resource sets indicated by the first indication information is for non-codebook-based PUSCH. That is, the RRC parameter usage in the SRS-ResourceSet in the configuration information of the two SRS resource sets indicated by the first indication information is both set to "codebook" or both set to "non-codebook".

[0148] In some embodiments, the first SRS resource set and the second SRS resource set are configured in an RRC parameter, wherein the RRC parameter is an SRS resource set add or modify list (srs-ResourceSetToAddModList) or an SRS resource set add or modify list DCI-0-2 (srs-ResourceSetToAddModListDCI-0-2).

[0149] In some embodiments, the configuration information of the first SRS resource set indicates to follow a unified TCI state, and the configuration information of the second SRS resource set indicates to follow a unified TCI state.

[0150] For example, the configuration signaling corresponding to the first SRS resource set includes a first parameter or a second parameter; or the configuration signaling corresponding to the first SRS resource set includes a first parameter that is enabled, or the configuration signaling corresponding to the first SRS resource set includes a second parameter that is enabled. The first parameter is "followUnifiedTCIstateSRS" and the second parameter is "followUnifiedTCIstate."

[0151] For example, the configuration signaling corresponding to the second SRS resource set configures the first parameter or the second parameter; or the first parameter in the configuration signaling corresponding to the second SRS resource set is enabled, or the second parameter in the configuration signaling corresponding to the second SRS resource set is enabled. The first parameter is: followUnifiedTCIstateSRS, and the second parameter is: followUnifiedTCIstate.

[0152] For example, the semantic field of followUnifiedTCIstateSRS being enabled may be as follows:

[0153] followUnifiedTCIstateSRS-r17ENUMERATED{enabled}.

[0154] In some embodiments, the first SRS resource set is associated with a TCI state among the K1 TCI states, and / or the second SRS resource set is associated with a TCI state among the K1 TCI states, and when K1>1, the first SRS resource set is associated with the first TCI state among the K1 TCI states, and the second SRS resource set is associated with the second TCI state among the K1 TCI states. That is, when K1>1, the first SRS resource set is associated with the first TCI state, and the second SRS resource set is associated with the second TCI state.

[0155] In some embodiments, when the first SRS resource set is associated with a TCI state among the K1 TCI states, and / or the second SRS resource set is associated with a TCI state among the K1 TCI states, and the K1 TCI states include only the first TCI state, both the first SRS resource set and the second SRS resource set are associated with the first TCI state; or, the first SRS resource set is associated with the first TCI state, and the second SRS resource set is not associated with a TCI state. That is, when K1=1, both the first SRS resource set and the second SRS resource set are associated with the first TCI state, or, the first SRS resource set is associated with the first TCI state, and the second SRS resource set is not associated with a TCI state.

[0156] In some embodiments, some or all of the two SRS resources are associated with a TCI state among the K1 TCI states, and when K1>1, one of the two SRS resources is associated with one of the K1 TCI states, and the other SRS resource among the two SRS resources is associated with another TCI state among the K1 TCI states.

[0157] In some embodiments, some or all of the two SRS resources are associated with a TCI state among the K1 TCI states, and when K1=1, the two SRS resources are both associated with one TCI state among the K1 TCI states; or, one SRS resource of the two SRS resources is associated with a TCI state among the K1 TCI states, and the other SRS resource of the two SRS resources is not associated with a TCI state.

[0158] In some embodiments, one of the two SRS resources belongs to the first SRS resource set, and the other of the two SRS resources belongs to the second SRS resource set.

[0164] In some embodiments, the terminal device receives second indication information sent by the network device, wherein the second indication information is indication information sent by the network device at least for indicating or activating the TCI state.

[0165] In some embodiments, the second indication information is carried via first MAC CE signaling; wherein the first MAC CE signaling further includes at least one of the following: serving cell indication information, downlink BWP indication information, uplink BWP indication information, one or more TCI quantity indication fields, one or more TCI type indication fields, and one or more TCI status indication fields.

[0169] Specifically, each TCI quantity indication field in the one or more TCI quantity indication fields indicates that a code point corresponds to one or more TCI states.

[0170] Specifically, each TCI type indication field in the one or more TCI type indication fields is used to indicate that the corresponding TCI state is a downlink TCI state, an uplink TCI state, or a combined TCI state.

[0172] Specifically, one or more TCI status indication fields, each TCI status indication field indicates whether a corresponding TCI status exists. Optionally, the TCI status indication field and another TCI status indication field are in the same byte (Octet, Oct).

[0173] Specifically, one or more TCI quantity indication fields are provided, each indicating a codepoint corresponding to N TCI states. Therefore, the total number of uplink and downlink TCI states can be indicated, reducing the number of bits and compressing MAC CE signaling overhead. Optionally, each TCI quantity indication field has 2 bits, or each TCI quantity indication field has 3 bits.

[0174] Optionally, each TCI quantity indication field indicates that one codepoint corresponds to one or two joint TCI states. This embodiment may specifically correspond to Example 1 above.

[0175] Optionally, the value of N can be 1, 2, 3, or 4. Therefore, the protocol design and system implementation are simple, and most of the performance gains of multi-TRP (M-TRP) can be achieved, and network configuration and scheduling are more flexible. Optionally, the number of downlink TCI states is less than or equal to 2. Optionally, the number of uplink TCI states is less than or equal to 2. This embodiment specifically corresponds to Example 2 above.

[0176] Optionally, N can be 1, 2, 3, 4, 5, or 6. Therefore, more TRPs can be supported for downlink transmission, which can improve downlink performance in some scenarios and provide greater freedom for network optimization. Optionally, the number of downlink TCI states is less than or equal to 4. Optionally, the number of uplink TCI states is less than or equal to 2. This embodiment specifically corresponds to Example 2 above.

[0177] Optionally, the value of N can be 1, 2, 3, 4, 5, 6, 7, or 8. Therefore, more TRPs can be supported for downlink and uplink transmissions, which can improve downlink and uplink performance in some scenarios and provide greater freedom for network optimization. Optionally, the number of downlink TCI states is less than or equal to 4. Optionally, the number of uplink TCI states is less than or equal to 4. This embodiment specifically corresponds to Example 2 above.

[0178] Optionally, each TCI quantity indication field indicates that one codepoint corresponds to one, two, three, or four joint TCI states. Therefore, more TRPs can be supported for downlink and uplink transmission. In some scenarios, this improves downlink and uplink performance, providing greater freedom for network optimization. Optionally, the number of TCI quantity indication fields is 8 or 16. This embodiment specifically corresponds to Example 1 above.

[0179] Specifically, the TCI state type indication field in one or more TCI type indication fields is used to indicate whether the corresponding TCI state is a downlink TCI state, an uplink TCI state, or a combined TCI state.

[0183] Specifically, the TCI status indication information (i.e., the second indication information) may optionally be 7 bits long if the TCI status indication information is used to indicate the uplink TCI status. Therefore, more uplink TCI statuses can be indicated, thereby improving network scheduling flexibility.

[0184] Specifically, the TCI state indication information (ie, the second indication information), optionally, if the TCI state indication information is used to indicate the uplink TCI state, then the most significant bit in the TCI state indication information is a reserved bit, and the remaining 6 bits indicate the UL TCI state.

[0185] Optionally, the first MAC CE signaling may also include information indicating the number of TCI state subsets (or DCI code points), which may indicate a value that is a positive integer between 1 and S, where S may be the number of TCI quantity indication fields. This allows the UE to reduce the need to read / parse some bits of information, reducing terminal implementation complexity. Optionally, the value may be the number of codepoints in the first field of the DCI corresponding to the TCI state indicated in the second MAC CE; optionally, the first field may be the Transmission Configuration Indication field in the DCI.

[0186] In some embodiments, the maximum number of TCI states indicated by the first MAC CE is 32, 48, or 64; or, the maximum number of TCI states activated by the first MAC CE is 32, 48, or 64. That is, the maximum number of TCI states indicated by the second indication information is 32, 48, or 64.

[0187] Among them, when the maximum number is 32, a maximum of 2 TRP transmissions are supported for both uplink and downlink, (2+2)*8=32.

[0188] Among them, when the maximum number is 48, it supports up to 4 downlink TRP transmissions and 2 uplink TRP transmissions, which improves downlink transmission performance, increases the flexibility of network configuration and scheduling, and also controls the UE implementation complexity within a certain range.

[0189] Among them, when the maximum number is 64, it supports up to 4 TRP transmissions in the downlink and 4 TRP transmissions in the uplink, improving the downlink and uplink transmission performance and increasing the flexibility of network configuration and scheduling at the cost of UE implementation complexity.

[0190] In some embodiments, when K1 > 1, the first TCI state is determined based on a TCI state identifier among the K1 TCI states, and / or the second TCI state is determined based on a TCI state identifier among the K1 TCI states. That is, the TCI states corresponding to the first and second SRS resource sets can be determined based on a preset rule (i.e., the TCI state identifier), effectively reducing product implementation complexity.

[0191] For example, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states, and / or the second TCI state is the TCI state with the largest identifier among the K1 TCI states.

[0192] For another specific example, the first TCI state is the TCI state with the largest identifier among the K1 TCI states, and / or the second TCI state is the TCI state with the smallest identifier among the K1 TCI states.

[0193] It should be noted that the TCI status identifier can also be called the TCI status index or TCI status number, which is not limited in this application.

[0194] In some embodiments, when K1>1, the first TCI state is determined based on the position information of the K1 TCI states in the second indication information, and / or the second TCI state is determined based on the position information of the K1 TCI states in the second indication information; wherein the second indication information is indication information sent by the network device for at least indicating or activating a TCI state, and the TCI states indicated or activated by the second indication information include at least the K1 TCI states. That is, the TCI states corresponding to the first SRS resource set and the second SRS resource set can be determined based on a preset rule (i.e., the position information of the K1 TCI states in the second indication information), which can effectively reduce product implementation complexity.

[0195] For example, the first TCI state is the TCI state with the earliest position among the K1 TCI states in the second indication information, and / or the second TCI state is the TCI state with the latest position among the K1 TCI states in the second indication information.

[0196] For example, the first TCI state is the TCI state with the last position among the K1 TCI states in the second indication information, and / or the second TCI state is the TCI state with the first position among the K1 TCI states in the second indication information.

[0197] In some embodiments, when K1>1, the network device may indicate the first TCI state via third indication information, and / or the network device may indicate the second TCI state via fourth indication information. That is, the network device may indicate the first TCI state among the K1 TCI states via the third indication information, and / or the network device may indicate the second TCI state among the K1 TCI states via the fourth indication information.

[0198] In some embodiments, the third indication information is used to indicate that the first TCI state is the TCI state with the smallest identifier among the K1 TCI states, or the third indication information is used to indicate that the first TCI state is the TCI state with the largest identifier among the K1 TCI states, or the third indication information is used to indicate that the first TCI state is the TCI state with the earliest position among the K1 TCI states in the second indication information, or the third indication information is used to indicate that the first TCI state is the TCI state with the latest position among the K1 TCI states in the second indication information; wherein the second indication information is indication information sent by the network device for at least indicating or activating a TCI state, and the TCI states indicated or activated by the second indication information include at least the K1 TCI states. Therefore, the TCI state corresponding to the first SRS resource set can be determined based on the third indication information, thereby reducing signaling overhead.

[0199] In some embodiments, the fourth indication information is used to indicate that the second TCI state is the TCI state with the smallest identifier among the K1 TCI states, or the fourth indication information is used to indicate that the second TCI state is the TCI state with the largest identifier among the K1 TCI states, or the fourth indication information is used to indicate that the second TCI state is the TCI state with the earliest position among the K1 TCI states in the second indication information, or the fourth indication information is used to indicate that the second TCI state is the TCI state with the latest position among the K1 TCI states in the second indication information; wherein the second indication information is indication information sent by the network device for at least indicating or activating a TCI state, and the TCI states indicated or activated by the second indication information include at least the K1 TCI states. Therefore, the TCI state corresponding to the second SRS resource set can be determined based on the fourth indication information, which can reduce signaling overhead.

[0200] For example, the third indication information is used to indicate that the first TCI state is the TCI state with the smallest identifier among K1 TCI states, and the fourth indication information is used to indicate that the second TCI state is the TCI state with the largest identifier among K1 TCI states.

[0201] For another specific example, the third indication information is used to indicate that the first TCI state is the TCI state with the largest identifier among K1 TCI states, and the fourth indication information is used to indicate that the second TCI state is the TCI state with the smallest identifier among K1 TCI states.

[0202] For example, the third indication information is used to indicate that the first TCI state is the TCI state with the earliest position among the K1 TCI states in the second indication information, and the fourth indication information is used to indicate that the second TCI state is the TCI state with the latest position among the K1 TCI states in the second indication information.

[0203] For example, the third indication information is used to indicate that the first TCI state is the TCI state with the last position among the K1 TCI states in the second indication information, and the fourth indication information is used to indicate that the second TCI state is the TCI state with the first position among the K1 TCI states in the second indication information.

[0204] In some embodiments, if the terminal device does not obtain the third indication information, or if the network device is not configured with the third indication information, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states; and / or, if the terminal device obtains the third indication information, or if the network device is configured with the third indication information, the first TCI state is the TCI state with the largest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the first SRS resource set can be determined based on whether the third indication information is obtained, or the TCI state corresponding to the first SRS resource set can be determined based on whether the network device is configured with the third indication information, thereby reducing signaling overhead.

[0205] In some embodiments, when the terminal device does not obtain the third indication information, or when the network device is not configured with the third indication information, the first TCI state is the TCI state with the largest identifier among the K1 TCI states; and / or, when the terminal device obtains the third indication information, or when the network device is configured with the third indication information, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the first SRS resource set can be determined based on whether the third indication information is obtained, or the TCI state corresponding to the first SRS resource set can be determined based on whether the network device is configured with the third indication information, thereby reducing signaling overhead.

[0206] In some embodiments, if the terminal device does not obtain the fourth indication information, or if the network device is not configured with the fourth indication information, the second TCI state is the TCI state with the smallest identifier among the K1 TCI states; and / or, if the terminal device obtains the fourth indication information, or if the network device is configured with the fourth indication information, the second TCI state is the TCI state with the largest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the second SRS resource set can be determined based on whether the fourth indication information is obtained, or the TCI state corresponding to the second SRS resource set can be determined based on whether the network device is configured with the fourth indication information, thereby reducing signaling overhead.

[0207] In some embodiments, if the terminal device does not obtain the fourth indication information, or if the network device is not configured with the fourth indication information, the second TCI state is the TCI state with the largest identifier among the K1 TCI states; and / or, if the terminal device obtains the fourth indication information, or if the network device is configured with the fourth indication information, the second TCI state is the TCI state with the smallest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the second SRS resource set can be determined based on whether the fourth indication information is obtained, or the TCI state corresponding to the second SRS resource set can be determined based on whether the network device is configured with the fourth indication information, thereby reducing signaling overhead.

[0208] For example, when the terminal device does not obtain the third indication information and the fourth indication information, or when the network device is not configured with the third indication information and the fourth indication information, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states, and the second TCI state is the TCI state with the largest identifier among the K1 TCI states; and when the terminal device obtains the third indication information and the fourth indication information, or when the network device is configured with the third indication information and the fourth indication information, the first TCI state is the TCI state with the largest identifier among the K1 TCI states, and the second TCI state is the TCI state with the smallest identifier among the K1 TCI states.

[0209] For another specific example, when the terminal device has not obtained the third indication information and the fourth indication information, or when the network device is not configured with the third indication information and the fourth indication information, the first TCI state is the TCI state with the largest identifier among the K1 TCI states, and the second TCI state is the TCI state with the smallest identifier among the K1 TCI states; and, when the terminal device obtains the third indication information and the fourth indication information, or when the network device is configured with the third indication information and the fourth indication information, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states, and the second TCI state is the TCI state with the largest identifier among the K1 TCI states.

[0210] In some embodiments, when the third indication information has a first value, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states; and / or, when the third indication information has a second value, the first TCI state is the TCI state with the largest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the first SRS resource set can be determined based on the third indication information, providing a flexible signaling structure and facilitating future expansion to situations where K1 > 2.

[0211] In some embodiments, when the third indication information has a first value, the first TCI state is the TCI state with the highest identifier among the K1 TCI states; and / or, when the third indication information has a second value, the first TCI state is the TCI state with the lowest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the first SRS resource set can be determined based on the third indication information, providing a flexible signaling structure and facilitating future expansion to situations where K1 > 2.

[0212] In some embodiments, when the fourth indication information has a first value, the second TCI state is the TCI state with the smallest identifier among the K1 TCI states; and / or, when the fourth indication information has a second value, the second TCI state is the TCI state with the largest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the second SRS resource set can be determined based on the fourth indication information, providing a flexible signaling structure and facilitating future expansion to situations where K1 > 2.

[0213] In some embodiments, when the fourth indication information has the first value, the second TCI state is the TCI state with the largest identifier among the K1 TCI states; and / or, when the fourth indication information has the second value, the second TCI state is the TCI state with the smallest identifier among the K1 TCI states. Therefore, the TCI state corresponding to the second SRS resource set can be determined based on the fourth indication information, providing a flexible signaling structure and facilitating future expansion to situations where K1 > 2.

[0214] For example, when the third indication information is the first value and the fourth indication information is the first value, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states, and the second TCI state is the TCI state with the largest identifier among the K1 TCI states; and, when the third indication information is the second value and the fourth indication information is the second value, the first TCI state is the TCI state with the largest identifier among the K1 TCI states, and the second TCI state is the TCI state with the smallest identifier among the K1 TCI states.

[0215] For another specific example, when the third indication information is the first value and the fourth indication information is the first value, the first TCI state is the TCI state with the largest identifier among the K1 TCI states, and the second TCI state is the TCI state with the smallest identifier among the K1 TCI states; and, when the third indication information is the second value and the fourth indication information is the second value, the first TCI state is the TCI state with the smallest identifier among the K1 TCI states, and the second TCI state is the TCI state with the largest identifier among the K1 TCI states.

[0216] In some embodiments, the SRS resource set with the smallest SRS resource set ID among the two SRS resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state with the smallest identifier (ID) among K1=2 TCI states, and the SRS resource set with the largest SRS resource set ID among the two SRS resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state with the largest identifier (ID) among K1=2 TCI states.

[0217] In some embodiments, the SRS resource set with the largest SRS resource set ID among the two SRS resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state with the smallest identifier (ID) among K1=2 TCI states, and the SRS resource set with the smallest SRS resource set ID among the two SRS resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state with the largest identifier (ID) among K1=2 TCI states.

[0218] In some embodiments, the SRS resource set with the smallest SRS resource set ID among the two resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state that is positioned closest to the front in the second indication information among K1=2 TCI states, and the SRS resource set with the largest SRS resource set ID among the two resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state that is positioned closest to the back in the second indication information among K1=2 TCI states.

[0219] In some embodiments, the SRS resource set with the largest SRS resource set ID among the two resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state that is positioned closest to the front in the second indication information among K1=2 TCI states, and the SRS resource set with the smallest SRS resource set ID among the two resource sets (i.e., the first SRS resource set and the second SRS resource set) corresponds to the TCI state that is positioned closest to the back in the second indication information among K1=2 TCI states.

[0220] In some embodiments, the third indication information is included in the configuration information of the first SRS resource set, and / or the fourth indication information is included in the configuration information of the second SRS resource set.

[0221] In some embodiments, when the configuration information of the first SRS resource set includes the third indication information, the configuration information of the first SRS resource set does not include: followUnifiedTCIstateSRS or followUnifiedTCIstate, or, the configuration information of the first SRS resource set includes: disabled followUnifiedTCIstateSRS or followUnifiedTCIstate, or, the terminal device ignores followUnifiedTCIstateSRS or followUnifiedTCIstate in the configuration information of the first SRS resource set.

[0222] In some embodiments, when the configuration information of the second SRS resource set includes the fourth indication information, the configuration information of the second SRS resource set does not include followUnifiedTCIstateSRS or followUnifiedTCIstate, or the configuration information of the second SRS resource set includes disabled followUnifiedTCIstateSRS or followUnifiedTCIstate, or the terminal device ignores followUnifiedTCIstateSRS or followUnifiedTCIstate in the configuration information of the second SRS resource set.

[0223] In some embodiments, when K1>1, the uplink transmission spatial filter or spatial relationship corresponding to the first SRS resource set is determined based on the first TCI state, and / or the uplink transmission spatial filter or spatial relationship corresponding to the second SRS resource set is determined based on the second TCI state.

[0224] In some embodiments, when K1>1, an uplink transmit spatial filter (UL TX spatial filter) or spatial relation corresponding to the PUSCH associated with the first SRS resource set is determined based on the first TCI state and / or the first SRS resource set. For example, the uplink transmit spatial filter or spatial relation corresponding to the PUSCH associated with the first SRS resource set is determined based on the first TCI state and the first SRS resource set.

[0225] In some embodiments, when the TCI state among the K1 TCI states is a joint TCI state, the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set is determined based on the reference signal corresponding to typeD (type D) in the first TCI state and the first SRS resource set.

[0226] In some embodiments, when the TCI state among the K1 TCI states is an uplink TCI state (UL TCI state), the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set is determined based on the reference signal in the first TCI state and the first SRS resource set.

[0227] In some embodiments, when K1>1, an uplink transmit spatial filter (UL TX spatial filter) or spatial relation corresponding to the PUSCH associated with the second SRS resource set is determined based on the second TCI state and / or the second SRS resource set. For example, the uplink transmit spatial filter or spatial relation corresponding to the PUSCH associated with the second SRS resource set is determined based on the second TCI state and the second SRS resource set.

[0228] In some embodiments, when the TCI state among the K1 TCI states is a joint TCI state, the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the second SRS resource set is determined based on the reference signal corresponding to typeD (type D) in the second TCI state and the second SRS resource set.

[0229] In some embodiments, when the TCI state among the K1 TCI states is an uplink TCI state (UL TCI state), the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the second SRS resource set is determined based on the reference signal in the second TCI state and the second SRS resource set.

[0230] In some embodiments, when K1=1, the uplink transmit spatial filters or spatial relationships corresponding to the first SRS resource set and the second SRS resource set are both determined based on the first TCI state. For example, when K1=1, and the first SRS resource set and the second SRS resource set are both associated with the first TCI state, the uplink transmit spatial filters or spatial relationships corresponding to the first SRS resource set and the second SRS resource set are both determined based on the first TCI state.

[0231] In some embodiments, when K1=1, the uplink transmit spatial filter or spatial relationship corresponding to the first SRS resource set is determined based on the first TCI state, and the current PUSCH transmission does not consider the second SRS resource set. Specifically, for example, when K1=1, and the first SRS resource set is associated with the first TCI state, and the second SRS resource set is not associated with a TCI state, the uplink transmit spatial filter or spatial relationship corresponding to the first SRS resource set is determined based on the first TCI state, and the current PUSCH transmission does not consider the second SRS resource set.

[0232] In some embodiments, when K1=1, the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set and the second SRS resource set is determined based on the first TCI state and / or the first SRS resource set. For example, when K1=1, and the first SRS resource set and the second SRS resource set are both associated with the first TCI state, the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set and the second SRS resource set is determined based on the first TCI state and / or the first SRS resource set.

[0233] In some embodiments, the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set is determined based on the first TCI state and the first SRS resource set, and the current PUSCH transmission does not consider the second SRS resource set. Specifically, for example, when K1=1, and the first SRS resource set is associated with the first TCI state, and the second SRS resource set is not associated with a TCI state, the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH associated with the first SRS resource set is determined based on the first TCI state and the first SRS resource set, and the current PUSCH transmission does not consider the second SRS resource set.

[0234] In some embodiments, the K1 TCI states belong to N TCI states;

[0235] At least some of the N TCI states are activated TCI states corresponding to uplink transmission. The N TCI states are configured or indicated by a network device, N is a positive integer, and K1≤N.

[0236] Optionally, for a terminal device, at least some of the N TCI states are used to determine uplink transmission; for a network device, at least some of the N TCI states are used to indicate uplink transmission.

[0237] For example, K1 of the N TCI states are used for uplink transmission, and K2 of the N TCI states are used for downlink transmission. Here, 0<=K1<=N, and 0<=K2<=N. For example, K1=K2, or N=K1 and K2=0, or other combinations.

[0238] For example, K1=N, and the N TCI states are N uplink TCI states; or, K1=N, and the N TCI states are N joint TCI states, which are used for both uplink transmission and downlink transmission.

[0239] In some embodiments, the network device indicates the K1 TCI states via fifth indication information. In other words, the network device can indicate K1 TCI states out of N TCI states via the fifth indication information. Therefore, in this embodiment, the introduction of new indication information (i.e., the fifth indication information) allows for independent configuration of multi-TRP (M-TRP) transmission for uplink and downlink, reducing terminal implementation complexity and facilitating support for this feature by a wider range of terminal types.

[0240] In some embodiments, the fifth indication information is carried by one of the following: RRC signaling, MAC CE signaling, and DCI signaling.

[0241] It should be noted that RRC has good reliability but large delay; DCI has small delay and small signaling overhead, but poor reliability; MAC CE has better reliability than DCI, and both signaling overhead and delay are smaller than RRC.

[0242] In some embodiments, the fifth indication information is used to indicate that the K1 TCI states are selected sequentially from the N TCI states according to a first order. Therefore, in this embodiment, the K1 TCI states can be selected from the N TCI states according to a preset rule (i.e., the first order), which can effectively reduce product implementation complexity.

[0243] In some embodiments, the first order is an ascending order of TCI status identifiers, or an ascending order of TCI status identifiers. Of course, the first order may also be another type of order, such as an ascending order of odd-numbered TCI status identifiers or an ascending order of even-numbered TCI status identifiers, which is not limited in this application.

[0244] For example, the fifth indication information is used to indicate that the K1 TCI states are K1 TCI states selected from the N TCI states in ascending order of TCI state identifiers.

[0245] For another specific example, the fifth indication information is used to indicate that the K1 TCI states are K1 TCI states selected from the N TCI states in descending order of TCI state identifiers.

[0246] In some embodiments, the first order may be agreed upon by a protocol, or the first order may be configured by a network device.

[0247] In some embodiments, the fifth indication information is used to indicate that the K1 TCI states are selected sequentially according to the position order of the N TCI states in the second indication information. The second indication information is indication information sent by the network device for at least indicating or activating TCI states, and the TCI states indicated or activated by the second indication information include at least the N TCI states. Therefore, in this embodiment, the K1 TCI states can be selected from the N TCI states according to a preset rule (i.e., the position order of the N TCI states in the second indication information), effectively reducing product implementation complexity.

[0248] In some embodiments, the positions of the N TCI states in the second indication information are in a sequence from front to back, or the positions of the N TCI states in the second indication information are in a sequence from back to front.

[0249] For example, the fifth indication information is used to indicate that the K1 TCI states are K1 TCI states selected sequentially from the front to the back according to the positions of the N TCI states in the second indication information.

[0250] For another specific example, the fifth indication information is used to indicate that the K1 TCI states are K1 TCI states selected sequentially from the back to the front according to the positions of the N TCI states in the second indication information.

[0251] In some embodiments, the N TCI states are indicated by the network device through sixth indication information. That is, the network device may directly indicate the N TCI states, or the network device may indicate the N TCI states from a plurality of preconfigured TCI states.

[0252] In some embodiments, the N TCI states are indicated by the network device via second indication information. The second indication information is indication information sent by the network device for at least indicating or activating TCI states, and the TCI states indicated or activated by the second indication information include at least the N TCI states. That is, the network device can directly indicate the N TCI states, or the network device can indicate the N TCI states from a plurality of preconfigured TCI states. Optionally, in this case, the second indication information and the aforementioned sixth indication can be the same indication information.

[0253] In some embodiments, the N TCI states are determined based on the second indication information from TCI states indicated by the network device via sixth indication information; the second indication information is indication information sent by the network device for at least indicating or activating a TCI state, and the TCI states indicated or activated by the second indication information include at least the N TCI states. Specifically, for example, the network device may indicate multiple TCI states via the sixth indication information and indicate N TCI states of the multiple TCI states via the second indication information.

[0254] In some embodiments, the sixth indication information is carried by one of the following: RRC signaling, MAC CE signaling, and DCI signaling.

[0255] For example, the sixth indication information may be DCI signaling, such as the sixth indication information is transmitted through a first field in the DCI signaling, where the first field is a transmission configuration indication field in the DCI signaling.

[0256] In some embodiments, the terminal device may determine one or more of the following information based on the sixth indication information:

[0257] PDSCH DMRS corresponding QCL information (Quasi co-location);

[0258] QCL information corresponding to PDCCH DMRS, or QCL information corresponding to DMRS corresponding to some CORESETs;

[0259] QCL information corresponding to at least part of the CSI-RS;

[0260] PUSCH uplink transmit spatial filter (UL TX spatial filter);

[0261] an uplink transmit spatial filter for at least part of the PUCCH;

[0262] Uplink transmission spatial filter for at least part of the SRS.

[0263] Optionally, an RRC parameter is configured in the SRS resource set (SRS resource set) corresponding to at least part of the SRS: followUnifiedTCIstateSRS-r17) for tracking the SRS in the unified TCI state.

[0264] Optionally, the sixth indication information and the second indication information may be the same information. For example, if only one codepoint corresponds to a TCI state, then no additional DCI is needed to indicate the activated TCI state.

[0265] Optionally, the sixth indication information is transmitted via DCI signaling. Optionally, the sixth indication information is transmitted via the Transmission Configuration Indication field in the DCI signaling. For example, when there are multiple codepoints corresponding to TCI states, the DCI is required to additionally indicate which TCI state corresponding to the codepoint is used as the activated TCI state.

[0266] Optionally, the DCI carrying the sixth indication information is DCI format 1_1 and / or DCI format 1_2, where DCI format 1_1 or DCI format 1_2 can simultaneously schedule data or not schedule downlink transmission (with or without, if applicable, DL assignment).

[0267] Optionally, the DCI carrying the sixth indication information is DCI format 1_1 and / or DCI format 1_2 and / or DCI format 0_1 ​​and / or DCI format 0_2, wherein DCI format 1_1 / 1_2 can simultaneously schedule data or not schedule downlink transmission (with or without, if applicable, DL assignment), and DCI format 0_1 / 0_2 can simultaneously schedule data or not schedule uplink transmission (with or without, if applicable, UL assignment).

[0268] Optionally, if downlink transmission is not scheduled (without DL assignment), for DCI format 1_1 / 1_2, the terminal device can make the following assumptions (or, in other words, DCI format 1_1 / 1_2 satisfies the following conditions):

[0269] The cyclic redundancy check (CRC) of the DCI is scrambled by the configured scheduling radio network temporary identity (CS-RNTI);

[0270] The information fields in the DCI can be set as follows: Redundancy Version (RV) = all '1's, Modulation and Coding Scheme (MCS) = all '1's, New Data Indicator (NDI) = 0, frequency domain resource assignment (FDRA) type 0 all set to '0's, or, FDRA type 1 all set to '1's, or, dynamic Switch all set to '0's.

[0271] If at least one TCI state (denoted as TCI state X) among the one or more TCI states indicated by the sixth indication information is different from any of the previously indicated TCI states (considering the same direction, for example, if TCI state X is used for uplink transmission, the previously indicated TCI state for uplink transmission is considered to be different from TCI state X; if TCI state X is used for downlink transmission / reception, the previously indicated TCI state for downlink transmission / reception is considered to be different from TCI state X; if TCI state X is used for uplink transmission and downlink transmission / reception, the previously indicated TCI state for uplink transmission and downlink transmission / reception is considered to be different from TCI state X;), or if at least one TCI state (denoted as TCI state X) among the one or more TCI states indicated by the sixth indication information is different from any of all TCI states currently activated / used (activated, or applied) by the terminal device, starting from the first slot after at least BeamAppTime symbols after the last symbol of the first PUCCH, the TCI state X indicated by the sixth indication information takes effect, that is, the terminal device can determine the TCI state according to the TCI state X. X determines the uplink transmit spatial filter, and / or the QCL information corresponding to the downlink transmission / reception, wherein the first PUCCH transmission carries the hybrid automatic repeat request-acknowledgement (HARQ-ACK) information corresponding to the first indication information DCI.

[0272] Some additional examples are given for the above. Taking the example that a DCI can indicate up to two TCI states for downlink transmission / reception (DL operation, or DL ​​transmission / reception), other cases (TCI states for uplink, or TCI states for both uplink and downlink) can be expanded similarly. Suppose the network previously indicated TCI state A1 and TCI state A2 for downlink transmission. The current DCI indication signal contains TCI state X, and TCI state X is different from TCI state A1 / A2. In this case, the above process needs to be considered to determine when TCI state X can be used (can be applied). For another example, the terminal device currently uses one or two TCI states (denoted as A1, A2) to determine the QCL information corresponding to the downlink transmission. The current DCI indication signal contains TCI state X, and TCI state X is different from TCI state A1 / A2. In this case, the above process needs to be considered to determine when TCI state X can be used (can be applied).

[0273] In an embodiment of the present application, uplink transmission is performed based on a certain TCI state, or the TCI state is used for uplink transmission, that is, the spatial relationship corresponding to the uplink transmission is determined based on the TCI state, or the corresponding uplink transmit spatial filter is determined. For example, if the TCI state is a UL TCI state, the spatial relationship for the uplink transmission or the uplink transmit spatial filter is determined based on the reference signal in the UL TCI state. For another example, if the TCI state is a joint TCI state, the spatial relationship for the uplink transmission or the uplink transmit spatial filter is determined based on the reference signal corresponding to type D (typeD) in the joint TCI state.

[0274] In some embodiments, the terminal device sends first terminal capability information;

[0275] The first terminal capability information is used to indicate that the terminal device supports Z1 unified TCI states for uplink transmission or uplink repeated transmission, or the first terminal capability information is used to indicate that the terminal device supports a code point in the transmission configuration indication field in the DCI to activate or indicate a maximum of Z1 unified TCI states for uplink transmission or uplink repeated transmission, or the first terminal capability information is used to indicate that the terminal device supports Z1 unified TCI states for uplink transmission or uplink repeated transmission on the CG PUSCH, wherein Z1 is a positive integer and Z1>1.

[0276] In other words, the terminal device can report the first terminal capability information to the network device, so that the network device can activate or indicate a unified TCI state for uplink transmission or uplink repeated transmission based on the first terminal capability information.

[0277] For example, Z1 is 2, or Z1 is 4.

[0278] In some embodiments, the first terminal capability information is reported according to at least one of the following granularities:

[0279] Frequency band granularity, frequency band combination granularity, frequency band granularity in a frequency band combination, carrier granularity on each frequency band in a frequency band combination, frequency band range granularity, and terminal granularity.

[0280] For example, the first terminal capability information is reported at a per-band granularity, that is, the first terminal capability is reported for each band (i.e., different bands can independently report corresponding capabilities). Therefore, in this case, independent reporting of different bands can allow the terminal to have greater freedom. For example, the terminal can support a function on one or some bands, but not on other bands, thereby allowing more terminals to support this new function.

[0281] For example, the first terminal capability information is reported at a per-band combination granularity, that is, the first terminal capability is reported independently per band combination. Therefore, in this case, independent reporting of different band combinations allows the terminal greater flexibility. For example, a terminal may not support a function under a certain band combination, but support it under another band combination, thereby allowing more terminals to support this new function.

[0282] For example, the first terminal capability information is reported according to the frequency band granularity (per band per band combination) in the frequency band combination, that is, the first terminal capability is reported independently according to each frequency band in the frequency band combination (that is, the frequency bands in different frequency band combinations can be reported independently). Therefore, in this case, different frequency band combinations are reported independently, which allows the terminal to have greater freedom. For example, the terminal may not support this function under a certain CA, but support this function in certain frequency bands under another CA combination, thereby allowing more terminals to support this new function.

[0283] For example, the first terminal capability information is reported according to the carrier granularity on each frequency band in the frequency band combination (per CC per band per band combination or per Feature Set Per Component-carrier), that is, the first terminal capability is reported independently according to each carrier on each frequency band in the frequency band combination (that is, different carrier CCs in frequency bands in different frequency band combinations can be reported independently). Therefore, in this case, different frequency band combinations are reported independently, and different carriers on a band can also be reported independently, which can allow the terminal to have greater freedom, thereby allowing more terminals to support this new function.

[0284] For example, the first terminal capability information is reported at a per frequency range granularity, that is, the first terminal capability is reported per frequency range (FR) (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 are each reported independently). Therefore, in this case, independent reporting of different FRs allows the terminal to have greater freedom of implementation. For example, a terminal may not support this function in low frequency (FR1) but supports this function in FR2 (high frequency), thereby allowing more terminals to support this new function.

[0285] For example, the first terminal capability information is reported at a terminal granularity (per UE), that is, the first terminal capability is reported for the UE (i.e., per UE, meaning that if the UE reports this capability, this capability can be supported on all frequency bands). Therefore, in this case, the signaling overhead of reporting the terminal capability is reduced.

[0286] In some embodiments, the first terminal capability information is carried via one of the following: RRC signaling, MAC CE signaling.

[0287] In some embodiments, the terminal device sends second terminal capability information;

[0288] The second terminal capability information is used to indicate that the terminal device supports CG PUSCH.

[0289] In other words, the terminal device can report the second terminal capability information to the network device, so that the network device can determine whether the terminal device supports CG PUSCH based on the second terminal capability information.

[0290] In some embodiments, the second terminal capability information is reported according to at least one of the following granularities:

[0291] Frequency band granularity, frequency band combination granularity, frequency band granularity in a frequency band combination, carrier granularity on each frequency band in a frequency band combination, frequency band range granularity, and terminal granularity.

[0292] For example, the second terminal capability information is reported at a per-band granularity, that is, the second terminal capability is reported for each band (i.e., different bands can independently report corresponding capabilities). Therefore, in this case, independent reporting of different bands can allow the terminal to have greater freedom. For example, the terminal can support a function on one or more bands but not on other bands, thereby allowing more terminals to support this new function.

[0293] For example, the second terminal capability information is reported at a per-band combination granularity, meaning the second terminal capability is reported independently for each band combination. Therefore, in this case, independent reporting of different band combinations allows terminals greater flexibility. For example, a terminal may not support a function under a certain band combination, but support it under another band combination, allowing more terminals to support this new function.

[0294] For example, the second terminal capability information is reported according to the frequency band granularity (per band per band combination) in the frequency band combination, that is, the second terminal capability is reported independently according to each frequency band in the frequency band combination (that is, the frequency bands in different frequency band combinations can be reported independently). Therefore, in this case, different frequency band combinations are reported independently, which allows the terminal to have greater freedom. For example, the terminal may not support this function under a certain CA, but support this function in certain frequency bands under another CA combination, thereby allowing more terminals to support this new function.

[0295] For example, the second terminal capability information is reported according to the carrier granularity (per CC per band per band combination or per FSPC) on each frequency band in the frequency band combination, that is, the second terminal capability is reported independently according to each carrier on each frequency band in the frequency band combination (that is, different carrier CCs in frequency bands in different frequency band combinations can be reported independently). Therefore, in this case, different frequency band combinations are reported independently, and different carriers on a band can also be reported independently, which can give the terminal greater freedom, thereby allowing more terminals to support this new function.

[0296] For example, the second terminal capability information is reported at a per frequency range granularity, that is, the second terminal capability is reported per frequency range (FR) (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 are each reported independently). Therefore, in this case, independent reporting of different FRs allows the terminal to have greater freedom of implementation. For example, a terminal may not support this function in low frequency (FR1) but supports this function in FR2 (high frequency), thereby allowing more terminals to support this new function.

[0297] For example, the second terminal capability information is reported at a terminal granularity (per UE), that is, the second terminal capability is reported for the UE (i.e., per UE, meaning that if the UE reports this capability, this capability can be supported on all frequency bands). Therefore, in this case, the signaling overhead of reporting the terminal capability is reduced.

[0298] It should be noted that the reporting granularity of the first terminal capability information and the reporting granularity of the second terminal capability information can be the same or different. For example, the reporting granularity of the terminal capability information of one terminal is band, and the reporting granularity of the terminal capability information of another terminal is per CC per band per band combination. Because the uplink and downlink have different terminal capability requirements, using different options for uplink and downlink capabilities can be more conducive to terminal implementation.

[0299] In some embodiments, the second terminal capability information is carried via one of the following: RRC signaling, MAC CE signaling.

[0300] In some embodiments, the second terminal capability information and the first terminal capability information are transmitted through the same signaling, or the second terminal capability information and the first terminal capability information are transmitted through different signaling.

[0301] In some embodiments, the terminal device sends third terminal capability information;

[0302] The third terminal capability information is used to indicate that the terminal device supports Z2 unified TCI states for uplink transmission or uplink repeated transmission at the same time, or the third terminal capability information is used to indicate that the terminal device supports one code point in the transmission configuration indication field in the DCI to activate or indicate up to Z2 unified TCI states for uplink transmission or uplink repeated transmission at the same time, or the third terminal capability information is used to indicate that the terminal device supports Z2 unified TCI states on the CG PUSCH for uplink transmission or uplink repeated transmission at the same time, wherein Z2 is a positive integer and Z2>1.

[0303] In other words, the terminal device can report the third terminal capability information to the network device, so that the network device can activate or indicate a unified TCI state for uplink transmission or uplink repeated transmission based on the third terminal capability information.

[0304] For example, Z2 is 2, or Z2 is 4.

[0305] In some embodiments, the third terminal capability information is reported according to at least one of the following granularities:

[0306] Frequency band granularity, frequency band combination granularity, frequency band granularity in a frequency band combination, carrier granularity on each frequency band in a frequency band combination, frequency band range granularity, and terminal granularity.

[0307] For example, the third-terminal capability information is reported at a per-band granularity, meaning that the third-terminal capability is reported for each band (i.e., different bands can independently report corresponding capabilities). Therefore, in this case, independent reporting of different bands allows the terminal to have greater flexibility. For example, a terminal can support a function on one or more bands but not on other bands, allowing more terminals to support this new function.

[0308] For example, third-terminal capability information is reported at a per-band combination granularity, meaning that third-terminal capabilities are reported independently for each band combination. Therefore, in this case, independent reporting of different band combinations allows for greater flexibility in terminal implementation. For example, a terminal may not support a function under a certain band combination, but support it under another, allowing more terminals to support this new function.

[0309] For example, the third terminal capability information is reported according to the frequency band granularity (per band per band combination) in the frequency band combination, that is, the third terminal capability is reported independently for each frequency band in the frequency band combination (that is, the frequency bands in different frequency band combinations can be reported independently). Therefore, in this case, different frequency band combinations are reported independently, which allows the terminal to have greater freedom. For example, the terminal may not support this function under a certain CA, but support this function under certain frequency bands in another CA combination, thereby allowing more terminals to support this new function.

[0310] For example, the third terminal capability information is reported according to the carrier granularity (per CC per band per band combination or per FSPC) on each frequency band in the frequency band combination, that is, the third terminal capability is reported independently according to each carrier on each frequency band in the frequency band combination (that is, different carrier CCs in frequency bands in different frequency band combinations can be reported independently). Therefore, in this case, different frequency band combinations are reported independently, and different carriers on a band can also be reported independently, which can give the terminal greater freedom, thereby allowing more terminals to support this new function.

[0311] For example, the third terminal capability information is reported at a per-frequency-range granularity, that is, the third terminal capability is reported per-frequency-range (FR) (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 are each reported independently). Therefore, in this case, independent reporting of different FRs allows the terminal to have greater freedom of implementation. For example, a terminal may not support a certain function in low-frequency (FR1) but supports this function in FR2 (high frequency), thereby allowing more terminals to support this new function.

[0312] For example, the third terminal capability information is reported at a per-UE granularity, that is, the third terminal capability is reported per UE (i.e., per UE, meaning that if the UE reports this capability, it can be supported on all frequency bands). Therefore, in this case, the signaling overhead for reporting terminal capabilities is reduced.

[0313] It should be noted that the reporting granularity of the first terminal capability information and the reporting granularity of the third terminal capability information can be the same or different. For example, the reporting granularity of the terminal capability information of one terminal is band, and the reporting granularity of the terminal capability information of another terminal is per CC per band per band combination. Because the uplink and downlink have different terminal capability requirements, using different options for uplink and downlink capabilities can be more conducive to terminal implementation.

[0314] In some embodiments, the third terminal capability information is carried via one of the following: RRC signaling, MAC CE signaling.

[0315] Specifically, the difference between the first terminal capability information and the third terminal capability information can be shown through the following example.

[0316] Assume that the terminal device can support two TCI states (denoted as A1 and A2) through the first terminal capability information report. If the PUSCH has multiple repeated transmissions, then one of the TCI states is used in each PUSCH transmission, but different PUSCH transmissions can use different TCI states. For example, if the PUSCH is repeated four times, the corresponding TCI states may be A1, A2, A1, A2. That is, A1 and A2 are not used simultaneously in a transmission, or in other words, A1 and A2 are not used simultaneously to determine a PUSCH transmission.

[0317] Assuming that the terminal device can support two TCI states (denoted as A1 and A2) through third-party terminal capability information reporting, if the PUSCH has multiple repeated transmissions, then the two TCI states (i.e., A1+A2) are used to determine the PUSCH transmission during each transmission. For example, if the PUSCH is repeated four times, the corresponding TCI states are A1+A2, A1+A2, A1+A2, and A1+A2.

[0318] The following describes in detail a scheme for determining the uplink transmit spatial filter or spatial relationship corresponding to the dynamically scheduled PUSCH in this application (ie, Example 1), or a scheme for determining the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH configured with grant (CG) type 1 (CG PUSCH Type 1) (ie, Example 2), or a scheme for determining the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH configured with grant (CG) type 2 (CG PUSCH Type 2) (ie, Example 3).

[0319] In embodiment 1, a terminal device receives a first DCI, wherein the first DCI is used to schedule a first PUSCH; and the terminal device determines an uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH based on the first information; or, determines an uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH and the transmission of the first PUSCH based on the first information.

[0320] The first information is at least one of the following: a first TCI state among the K1 TCI states, a second TCI state among the K1 TCI states, the first SRS resource set, and the second SRS resource set.

[0321] In the case where K1>1, the first SRS resource set is associated with the first TCI state, and the second SRS resource set is associated with the second TCI state.

[0322] In which, when K1=1 and the K1 TCI states only include the first TCI state, the first SRS resource set and the second SRS resource set are both associated with the first TCI state; or, the first SRS resource set is associated with the first TCI state, and the second SRS resource set is not associated with the TCI state.

[0323] In embodiment 1, the terminal device receives the first DCI only after receiving the above-mentioned second indication information and / or sixth indication information.

[0324] Optionally, the format of the first DCI may be DCI format 0_0, or the format of the first DCI may be DCI format 0_1, or the format of the first DCI may be DCI format 0_2.

[0325] In some implementations of Example 1, when K1>1 and the first DCI is DCI format 0_0, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH based on the TCI state preset in the first TCI state and the second TCI state.

[0326] For example, when the format of the first DCI is DCI format 0_0, the terminal device can use the TCI state with the smallest identifier (ID) among K1 TCI states to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0327] For another example, when the format of the first DCI is DCI format 0_0, the terminal device can use the TCI state with the largest identifier (ID) among K1 TCI states to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0328] For another example, when the format of the first DCI is DCI format 0_0, the terminal device can use the TCI state with the most forward position in the third indication information among the K1 TCI states to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0329] For another example, when the format of the first DCI is DCI format 0_0, the terminal device can use the TCI state with the latest position in the third indication information among the K1 TCI states to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0330] In some implementations of Example 1, when K1>1 and the first DCI is DCI format 0_0, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH based on the TCI state indicated by the network device in the first TCI state and the second TCI state. Therefore, in this embodiment, the use of new indication information for flexible configuration can increase system flexibility and provide freedom for network optimization.

[0331] Specifically, if the first DCI is DCI format 0_0, the terminal device receives the eleventh indication information sent by the network device, wherein the eleventh indication information is used to indicate the TCI state between the first TCI state and the second TCI state; and the terminal device determines which TCI state between the first TCI state and the second TCI state to use to determine the uplink transmission spatial filter or spatial relationship corresponding to the first PUSCH based on the eleventh indication information.

[0332] Optionally, the eleventh indication information may be carried by one of the following: RRC signaling, MAC signaling, or DCI signaling.

[0333] Optionally, the eleventh indication information may indicate use of the TCI state with a smaller ID between the first TCI state and the second TCI state to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0334] Optionally, the eleventh indication information may indicate use of the TCI state with a larger ID between the first TCI state and the second TCI state to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0335] Optionally, the eleventh indication information may indicate the use of the TCI state closest to the front in the second indication information between the first TCI state and the second TCI state to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0336] Optionally, the eleventh indication information may indicate the use of the TCI state closest to the first TCI state and the second TCI state in the second indication information to determine the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH.

[0337] In some implementations of Example 1, when K1>1 and the first DCI is DCI format 0_1 ​​or DCI format 0_2, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH and the transmission of the first PUSCH based on the first TCI state, the first SRS resource set, the second TCI state and the second SRS resource set.

[0338] In some implementations of Example 1, when K1=1, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH and the transmission of the first PUSCH based on the first SRS resource set and the first TCI state.

[0339] In some implementations of Example 1, when K1=1, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH and the transmission of the first PUSCH based on the second SRS resource set and the first TCI state.

[0340] In some implementations of Example 1, if the first PUSCH needs to be repeatedly transmitted M times (for example, the first PUSCH may be transmitted in M ​​consecutive time slots; for another example, the first PUSCH may have M nominal repetitions), the first transmission is the initial transmission, and M is a positive integer.

[0341] Specifically, the first DCI is DCI format 0_1 ​​or DCI format 0_2. When the SRS resource indication field in DCI format 0_1 ​​or DCI format 0_2 indicates the first value (for example, the codepoint is "00"), the first SRS resource set and the corresponding first TCI state are used for M repeated transmissions of the first PUSCH.

[0342] It should be noted that the first SRS resource set and the corresponding first TCI state are used for M repeated transmissions of the first PUSCH. It can also be expressed as, the first SRS resource set and the corresponding first TCI state are used to determine the uplink transmit spatial filter or spatial relationship corresponding to the M repeated transmissions of the first PUSCH.

[0343] Specifically, the first DCI is DCI format 0_1 ​​or DCI format 0_2. When the SRS resource indication field in DCI format 0_1 ​​or DCI format 0_2 indicates a second value (for example, the codepoint is "01"), the second SRS resource set and the corresponding second TCI state are used for M repeated transmissions.

[0344] It should be noted that the second SRS resource set and the corresponding second TCI state are used for M repeated transmissions of the first PUSCH. It can also be expressed as, the second SRS resource set and the corresponding second TCI state are used to determine the uplink transmit spatial filter or spatial relationship corresponding to the M repeated transmissions of the first PUSCH.

[0345] Specifically, the first DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource indication field in DCI format 0_1 ​​or DCI format 0_2 indicates the third value (for example, the codepoint is "10").

[0346] Among them, when M=2, the first SRS resource set and the corresponding first TCI state are used for the first transmission of the first PUSCH (for example, the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), and the second SRS resource set and the corresponding second TCI state are used for the second transmission of the first PUSCH (for example, the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions).

[0347] Among them, when M>2, if the RRC information element PUSCH configuration (RRC IE PUSCH-Config) indicates cyclic mapping (ie, cyclic Mapping is enabled), the first SRS resource set and the corresponding first TCI state are used for the first transmission of the first PUSCH (e.g., the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), the second SRS resource set and the corresponding second TCI state are used for the second transmission of the first PUSCH (e.g., the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions), and the same mapping pattern is repeated in sequence until a total of M transmissions are completed (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 4th repeated transmissions, the corresponding SRS resource sets are: the first SRS resource set, the second SRS resource set, the first SRS resource set, and the second SRS resource set.

[0348] Among them, when M>2, if the RRC information element PUSCH configuration (RRC IE PUSCH-Config) indicates sequential mapping (ie, sequential Mapping is enabled), the first SRS resource set and the corresponding first TCI state are used for the first and second transmissions of the first PUSCH (for example, the first and second slots in M ​​consecutive slots, or the first and second retransmissions in M ​​nominal retransmissions), the second SRS resource set and the corresponding second TCI state are used for the third and fourth transmissions of the first PUSCH (for example, the third and fourth slots in M ​​consecutive slots, or the third and fourth retransmissions in M ​​nominal retransmissions), and the same subsequent mapping pattern is repeated in sequence until a total of M transmissions are made (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 8th repeated transmissions, the corresponding SRS resource sets are: the first SRS resource set, the first SRS resource set, the second SRS resource set, the second SRS resource set, the first SRS resource set, the first SRS resource set, the second SRS resource set, and the second SRS resource set.

[0349] Specifically, the first DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource indication field in DCI format 0_1 ​​or DCI format 0_2 indicates the fourth value (for example, the codepoint is "11").

[0350] Among them, when M=2, the second SRS resource set and the corresponding second TCI state are used for the first transmission of the first PUSCH (for example, the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), and the first SRS resource set and the corresponding first TCI state are used for the second transmission of the first PUSCH (for example, the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions).

[0351] Among them, when M>2, if RRC IE PUSCH-Config indicates cyclic mapping (ie, cyclic Mapping is enabled), the second SRS resource set and the corresponding second TCI state are used for the first transmission of the first PUSCH (for example, the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), the first SRS resource set and the corresponding first TCI state are used for the second transmission of the first PUSCH (for example, the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions), and the same subsequent mapping pattern is repeated in sequence until a total of M transmissions (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 4th repeated transmissions, the corresponding SRS resource sets are: the second SRS resource set, the first SRS resource set, the second SRS resource set, and the first SRS resource set.

[0352] Among them, when M>2, if RRC IE PUSCH-Config indicates sequential mapping (ie, sequential Mapping is enabled), the second SRS resource set and the corresponding second TCI state are used for the first and second transmissions of the first PUSCH (for example, the first and second slots in M ​​consecutive slots, or the first and second retransmissions in M ​​nominal retransmissions), the first SRS resource set and the corresponding first TCI state are used for the third and fourth transmissions of the first PUSCH (for example, the third and fourth slots in M ​​consecutive slots, or the third and fourth retransmissions in M ​​nominal retransmissions), and the same subsequent mapping pattern is repeated until a total of M transmissions (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 8th repeated transmissions, the corresponding SRS resource sets are: the second SRS resource set, the second SRS resource set, the first SRS resource set, the first SRS resource set, the second SRS resource set, the second SRS resource set, the first SRS resource set, and the first SRS resource set.

[0353] The above solution can be applied to the case where K1=2 TCI states or the case where K1=1 TCI state. In this case, the first TCI state and the second TCI state are the same TCI state, which refers to the K1=1 TCI state.

[0354] For the case of K1=1 TCI state, there may also be other solutions, for example, only using the first SRS resource set and the K1=1 TCI state to perform the first PUSCH transmission. An example is using the first SRS resource set and the K1=1 TCI state to perform M repeated transmissions of the first PUSCH.

[0355] For another example, only the second SRS resource set and K1=1 TCI state are used to perform the first PUSCH transmission. For example, the second SRS resource set and the K1=1 TCI state are used to perform M repetition transmissions of the first PUSCH.

[0356] For another example, the first DCI is DCI format 0_1 ​​or DCI format 0_2. At this time, the value of the SRS resource set indication field in DCI format 0_1 ​​or DCI format 0_2 is restricted, and can only take part of the values, not the other part of the values. For example, it can only take the aforementioned first value (for example, codepoint can only be "00"), or can only take the aforementioned second value (for example, codepoint can only be "01"), or can only take one of the aforementioned first value and second value (for example, codepoint can only be "00" or "01").

[0357] Optionally, the first SRS resource set corresponds to an "SRS resource indicator" indication field in the first DCI, and the second SRS resource set corresponds to a "Second SRS resource indicator" indication field in the first DCI. For example, the SRI indicated by the "SRS resource indicator" indication field in the first DCI corresponds to an SRS resource in the first SRS resource set, and the SRI indicated by the "Second SRS resource indicator" indication field in the first DCI corresponds to an SRS resource in the second SRS resource set.

[0358] In some implementations of Example 1, a terminal device receives twelfth indication information sent by a network device, where the twelfth indication information is used to indicate that, in a single transmission of the first PUSCH, transmission of the first PUSCH is determined based on both the first TCI state and the second TCI state. For example, based on the twelfth indication information, the terminal device determines, in each transmission of the first PUSCH (if there are multiple transmissions), the uplink transmit spatial filter or spatial relationship corresponding to the first PUSCH based on both the first TCI state and the second TCI state.

[0359] Optionally, the twelfth indication information may be carried by one of the following: RRC signaling, MAC CE signaling, or DCI signaling.

[0360] Optionally, the twelfth indication information may be configured for BWP, that is, the configuration granularity of the twelfth indication information is BWP.

[0361] Optionally, the twelfth indication information is configured through the RRC parameter PUSCH-Config.

[0362] In embodiment 2, the terminal device determines an uplink transmit spatial filter or spatial relationship corresponding to a second PUSCH and transmission of the second PUSCH according to the second information;

[0363] The second PUSCH is a PUSCH of CG type 1, the second PUSCH corresponds to a first SRS resource and / or a second SRS resource, the first SRS resource is one of the two SRS resources, and the second SRS resource is the other of the two SRS resources;

[0364] The second information is at least one of the following: a TCI state associated with the first SRS resource, a TCI state associated with the second SRS resource, the first SRS resource, and the second SRS resource.

[0365] In Example 2, the network device may configure one or more configured grant configurations (Configured Grant Configuration) for the terminal device. For example, one or more configuration grants on one BWP may be configured through RRC signaling. For ease of description, one of the grant configurations (the first grant configuration) is used as an example to introduce the subsequent solution.

[0366] Optionally, the first configuration authorization is a configured grant Type 1.

[0367] Optionally, when the first configuration authorization is configuration authorization type 1, the network device further includes an RRC uplink authorization configuration (rrc-ConfiguredUplinkGrant) in the RRC parameter configuration authorization configuration (configuredGrantConfig) for the first configuration authorization.

[0368] For example, the first SRS resource is indicated by the RRC parameter SRS resource indication (srs-ResourceIndicator) in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant.

[0369] For example, the second SRS resource is indicated by the RRC parameter SRS resource indication 2 (srs-ResourceIndicator2) in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant.

[0370] Optionally, the network device may further configure one or more of the following information for the first configuration authorization (for example, through RRC signaling):

[0371] Frequency hopping indication information in the frequency domain, such as intra-slot hopping and inter-slot hopping;

[0372] Demodulation Reference Signal (DMRS) indication information;

[0373] Resource allocation indication information, such as time domain and / or frequency domain resource allocation;

[0374] Power control parameter indication information;

[0375] Precoding indication information;

[0376] SRS resource indication information;

[0377] Repeated transmission instruction information;

[0378] Hybrid Automatic Repeat reQuest (HARQ) process indication information.

[0379] In embodiment 2, the information of the first authorization configuration is used, and part or all of the following information of pusch-Config in the RRC parameters is also used:

[0380] a. PUSCH data scrambling identity (dataScramblingIdentityPUSCH);

[0381] b. Transmission configuration (txConfig);

[0382] c. codebook subset (codebookSubset);

[0383] d. Maximum rank (maxRank);

[0384] e. Uplink Control Information (UCI) range on PUSCH (scaling of UCI-OnPUSCH).

[0385] In some implementations of Example 2, if the second PUSCH corresponds to the first SRS resource and the second SRS resource, the first SRS resource is associated with the first TCI state among the K1 TCI states, and the second SRS resource is associated with the second TCI state among the K1 TCI states. Therefore, the SRS resource can be directly associated with the TCI state, reducing the number of association levels and association complexity.

[0386] In some implementations of Example 2, if the second PUSCH corresponds to the first SRS resource and the second SRS resource, the first SRS resource belongs to the first SRS resource set, the second SRS resource belongs to the second SRS resource set, the first SRS resource set is associated with a first TCI state among the K1 TCI states, and the second SRS resource set is associated with a second TCI state among the K1 TCI states, then the first SRS resource is associated with the first TCI state, and the second SRS resource is associated with the second TCI state. Therefore, the association between the SRS resource set and the TCI state can be utilized to maintain consistency in processing under different PUSCH modes, thereby reducing protocol complexity.

[0387] In some implementations of Example 2, if the second PUSCH corresponds to the first SRS resource and the second SRS resource, the first SRS resource belongs to the second SRS resource set, the second SRS resource belongs to the first SRS resource set, the first SRS resource set is associated with a first TCI state among the K1 TCI states, and the second SRS resource set is associated with a second TCI state among the K1 TCI states, then the first SRS resource is associated with the second TCI state, and the second SRS resource is associated with the first TCI state. Therefore, the association between the SRS resource set and the TCI state can be utilized to maintain consistency in processing under different PUSCH modes, thereby reducing protocol complexity.

[0388] In some implementations of Example 2, when the second PUSCH corresponds to the first SRS resource and the second SRS resource, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the second PUSCH and the transmission of the second PUSCH based on the first TCI state, the first SRS resource, the second TCI state and the second SRS resource.

[0389] In some implementations of Embodiment 2, if the second PUSCH corresponds to the first SRS resource, the first SRS resource is associated with a first TCI state among the K1 TCI states.

[0390] In some implementations of Example 2, when the second PUSCH corresponds to the first SRS resource, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the second PUSCH and the transmission of the second PUSCH based on the first TCI state and the first SRS resource.

[0391] In some implementations of Example 2, when K1=1 and the second PUSCH corresponds to the first SRS resource and the second SRS resource, the terminal device can determine the uplink transmit spatial filter or spatial relationship corresponding to the second PUSCH and the transmission of the second PUSCH based on the first SRS resource and the K1=1 TCI state.

[0392] In some implementations of Example 2, when K1=1 and the second PUSCH corresponds to the first SRS resource and the second SRS resource, the terminal device can determine the uplink transmit spatial filter or spatial relationship corresponding to the second PUSCH and the transmission of the second PUSCH based on the second SRS resource and the K1=1 TCI state.

[0393] In some implementations of Embodiment 2, if the second PUSCH needs to be repeatedly transmitted M times (for example, the second PUSCH may be transmitted in M ​​consecutive time slots; for another example, the second PUSCH may have M nominal repetitions).

[0394] Specifically, when M=2, the first SRS resource corresponds to the first transmission of the second PUSCH (for example, the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), and the second SRS resource corresponds to the second transmission of the second PUSCH (for example, the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions).

[0395] Specifically, when M>2, if the RRC information element (IE) configuration grant configuration (ConfiguredGrantConfig) indicates cyclic mapping (cyclicMapping) (that is, cyclicMapping is enabled, for example, the value of the mapping mode (mappingPattern) is cyclicMapping), the first SRS resource and the second SRS resource are applied to the first and second transmissions of the second PUSCH, respectively (for example, the first and second slots in M ​​consecutive slots, or the first and second retransmissions in M ​​nominal retransmissions), and the same subsequent mapping pattern is repeated in sequence until a total of M transmissions (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 4th repeated transmissions, the corresponding SRS resources are: first SRS resource, second SRS resource, first SRS resource, and second SRS resource.

[0396] Specifically, when M>2, if the RRC information element (IE) configuration grant configuration (ConfiguredGrantConfig) indicates sequential mapping (ie, sequentialMapping) (ie, sequentialMapping is enabled, for example, the value of the mapping mode (mappingPattern) is sequentialMapping), the first SRS resource is applied to the first and second transmissions of the second PUSCH (e.g., the first and second slots in M ​​consecutive slots, or the first and second retransmissions in M ​​nominal retransmissions), and the second SRS resource is applied to the third and fourth transmissions of the second PUSCH (e.g., the third and fourth slots in M ​​consecutive slots, or the third and fourth retransmissions in M ​​nominal retransmissions), and the same subsequent mapping pattern is repeated in sequence until a total of M transmissions are made (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, the SRS resources corresponding to the 1st to 8th repeated transmissions are: first SRS resource, first SRS resource, second SRS resource, second SRS resource, first SRS resource, first SRS resource, second SRS resource, and second SRS resource.

[0397] The above solution can be used in the case where K1=2 TCI states. It can also be used in the case where K1=1 TCI state. In this case, the first TCI state and the second TCI state are the same TCI state, referring to the K1=1 TCI state, and the first SRS resource and the second SRS resource are used to determine the transmission of the second PUSCH.

[0398] For the case where K1=1 TCI state, there may also be another solution.

[0399] For example, only the first SRS resource and K1=1 TCI state are used to transmit the second PUSCH. For example, the first SRS resource and K1=1 TCI state are used to transmit M repetitions of the second PUSCH. Therefore, only one SRS resource can be used, reducing product implementation complexity.

[0400] For another example, only the second SRS resource and K1=1 TCI state are used to transmit the second PUSCH. For example, the second SRS resource and K1=1 TCI state are used to transmit the second PUSCH M times. Therefore, only one SRS resource can be used, reducing product implementation complexity.

[0401] In some implementations of Example 2, the first SRS resource set corresponds to the RRC parameter srs-ResourceIndicator in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant, and the second SRS resource set corresponds to the RRC parameter srs-ResourceIndicator2 in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant. For example, the SRI indicated by the RRC parameter srs-ResourceIndicator in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant corresponds to an SRS resource in the first SRS resource set, and the SRI indicated by the RRC parameter srs-ResourceIndicator2 in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant corresponds to an SRS resource in the second SRS resource set.

[0402] In some implementations of Example 2, a terminal device receives thirteenth indication information sent by a network device, where the thirteenth indication information is used to indicate that, in a single transmission of the second PUSCH, transmission of the second PUSCH is determined based on both the first TCI state and the second TCI state. For example, based on the thirteenth indication information, the terminal device determines, in each PUSCH transmission in CG PUSCH type 1 (if there are multiple transmissions), the uplink transmit spatial filter or spatial relationship corresponding to the second PUSCH based on both the first TCI state and the second TCI state.

[0403] Optionally, the thirteenth indication information may be carried by one of the following: RRC signaling, MAC CE, or DCI signaling.

[0404] Optionally, the thirteenth indication information may be configured for BWP, that is, the configuration granularity of the thirteenth indication information is BWP.

[0405] Optionally, the thirteenth indication information is for the first configuration authorization configuration, that is, the configuration granularity of the thirteenth indication information is configuration authorization configuration.

[0406] Optionally, the thirteenth indication information is configured through the RRC parameter configuredGrantConfig.

[0407] In embodiment 3, the terminal device receives a second DCI, wherein the second DCI is used to activate a third PUSCH, the third PUSCH is a PUSCH of CG type 2, the third PUSCH corresponds to a third SRS resource and / or a fourth SRS resource, the third SRS resource is one of the two SRS resources, and the fourth SRS resource is the other of the two SRS resources; and the terminal device can determine the uplink transmit spatial filter or spatial relationship corresponding to the third PUSCH and the transmission of the third PUSCH based on the third information; wherein the third information is at least one of the following: the TCI state associated with the third SRS resource, the TCI state associated with the fourth SRS resource, the third SRS resource, and the fourth SRS resource.

[0408] In Example 3, the network device may configure one or more configured grant configurations (Configured Grant Configuration) for the terminal device. For example, one or more configuration grants on one BWP may be configured through RRC signaling. For ease of description, one of the grant configurations (the first grant configuration) is used as an example to introduce the subsequent solution.

[0409] Optionally, the first configuration authorization is a configured grant Type 2.

[0410] Optionally, when the first configuration authorization is configuration authorization type 2, the network device does not include the RRC uplink authorization configuration (rrc-ConfiguredUplinkGrant) in the RRC parameter configuration authorization configuration (configuredGrantConfig) for the first configuration authorization.

[0411] For example, the third SRS resource is indicated by the RRC parameter SRS resource indication (srs-ResourceIndicator) in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant.

[0412] For example, the fourth SRS resource is indicated by the RRC parameter SRS resource indication 2 (srs-ResourceIndicator2) in the RRC parameter rrc-ConfiguredUplinkGrant corresponding to the first configuration grant.

[0413] Optionally, the network device may further configure one or more of the following information for the first configuration authorization (for example, through RRC signaling):

[0414] Frequency hopping indication information in the frequency domain, such as intra-slot hopping and inter-slot hopping;

[0415] Demodulation Reference Signal (DMRS) indication information;

[0416] Resource allocation indication information, such as time domain and / or frequency domain resource allocation;

[0417] Power control parameter indication information;

[0418] Precoding indication information;

[0419] SRS resource indication information;

[0420] Repeated transmission instruction information;

[0421] HARQ process indication information.

[0422] In embodiment 3, when DCI format 0_0 or DCI format 0_1 ​​activates the first configuration grant to transmit the third PUSCH, or when the third PUSCH corresponding to the first grant configuration is transmitted, the information of the first grant configuration is used, and the following part or all of the information of pusch-Config in the RRC parameter is also used:

[0423] PUSCH data scrambling identity (dataScramblingIdentityPUSCH);

[0424] Transmission configuration (txConfig);

[0425] codebook subset (codebookSubset);

[0426] Maximum rank (maxRank);

[0427] UCI range on PUSCH (scaling of UCI-OnPUSCH).

[0428] In embodiment 3, when DCI format 0_2 activates the first configuration grant, thereby transmitting the third PUSCH corresponding to the first configuration grant, the information configured by the first grant is used, and the following part or all of the information of pusch-Config in the RRC parameter is also used:

[0429] PUSCH data scrambling identity (dataScramblingIdentityPUSCH);

[0430] Transmission configuration (txConfig);

[0431] codebook subset DCI-0-2 (codebookSubsetDCI-0-2);

[0432] Maximum rank DCI-0-2 (maxRankDCI-0-2);

[0433] Scaling of UCI-OnPUSCH, resource allocation type 1 granularity DCI-0-2.

[0434] In embodiment 3, the second DCI may be DCI format 0_0, DCI format 0_1, or DCI format 0_2.

[0435] In embodiment 3, the second DCI satisfies one or more of the following conditions:

[0436] The CRC used by the second DCI is scrambled using the following parameters: the Configured Scheduling Radio Network Temporary Identity (CS-RNTI) configured with the parameter cs-RNTI, or the Group Configured Scheduling Radio Network Temporary Identity (G-CS-RNTI) configured with the parameter g-cs-RNTI;

[0437] The new data indication field in the second DCI is set to 0;

[0438] If the Configured Grant Downlink Feedback Information (CG-DFI) indication field exists in the second DCI, this field is set to 0;

[0439] The time domain resource allocation indication field in the second DCI indicates a row corresponding to one start and length indicator value (SLIV) indication.

[0440] Optionally, when there is only one first configuration grant, the provisions for activating some fields in the DCI of the first configuration grant are as shown in Table 1.

[0441] Table 1

[0442] DCI format 0_0 / 0_1 / 0_2 DCI format 1_0 / 1_2 / 4_1 DCI format 1_1 / 4_2 HARQ process number set to all '0's set to all '0's set to all '0's RV set to all '0's set to all '0's Enabled transport block: set to all '0's

[0443] Optionally, when there are multiple first configuration authorizations, the provisions for activating some fields in the DCI of the first configuration authorization are as shown in Table 2.

[0444] Table 2

[0445] DCI format 0_0 / 0_1 / 0_2 DCI format 1_0 / 1_2 / 4_1 DCI format 1_1 / 4_2 RV is set to all '0's Set to all '0's Enabled transport block: set to all '0s

[0446] In some implementations of Example 3, the third SRS resource is determined by the first SRS resource indication field in the second DCI, and / or the fourth SRS resource is determined by the second SRS resource indication field in the second DCI. Therefore, a preset rule can be used to determine the SRS resource based on the DCI fixed field, reducing product implementation complexity.

[0447] In some implementations of Embodiment 3, when the second DCI is DCI format 0_0, the third PUSCH corresponds to the third SRS resource.

[0448] In some implementations of Embodiment 3, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates the first value, the third PUSCH corresponds to the third SRS resource; or,

[0449] When the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates the second value, the third PUSCH corresponds to the fourth SRS resource; or

[0450] When the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates a third value, the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, wherein the third SRS resource is determined by the first SRS resource indication field in the second DCI, and the fourth SRS resource is determined by the second SRS resource indication field in the second DCI; or

[0451] When the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates the fourth value, the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, wherein the third SRS resource is determined by the second SRS resource indication field in the second DCI, and the fourth SRS resource is determined by the first SRS resource indication field in the second DCI.

[0452] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a first value (for example, the codepoint is "00"), the third PUSCH corresponds to a third SRS resource.

[0453] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a second value (for example, the codepoint is "01"), the third PUSCH corresponds to a fourth SRS resource.

[0454] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a third value (for example, the codepoint is "10"), then the third PUSCH corresponds to a third SRS resource and a fourth SRS resource, where the third SRS resource is determined by the "SRS resource indicator" indication field in the second DCI, and the fourth SRS resource is determined by the "Second SRS resource indicator" indication field in the second DCI.

[0455] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a fourth value (for example, the codepoint is "11"), then the third PUSCH corresponds to a third SRS resource and a fourth SRS resource, where the fourth SRS resource is determined by the "SRS resource indicator" indication field in the second DCI, and the third SRS resource is determined by the "Second SRS resource indicator" indication field in the second DCI.

[0456] Therefore, the SRS resources corresponding to the third PUSCH can be determined based on the SRS resource set indication field in the second DCI, thereby increasing the flexibility of the system.

[0457] In some implementations of Embodiment 3, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates the first value, the third PUSCH corresponds to the third SRS resource; or,

[0458] When the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates the second value, the third PUSCH corresponds to the fourth SRS resource; or

[0459] When the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates a third value, the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, wherein the third SRS resource is determined by the first SRS resource indication field in the second DCI, and the fourth SRS resource is determined by the second SRS resource indication field in the second DCI; or

[0460] When the second DCI is DCI format 0_1 ​​or DCI format 0_2, and the SRS resource set indication field in the second DCI indicates a fourth value, the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, wherein the third SRS resource is determined by the first SRS resource indication field in the second DCI, and the fourth SRS resource is determined by the second SRS resource indication field in the second DCI.

[0461] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a first value (for example, the codepoint is "00"), the third PUSCH corresponds to a third SRS resource.

[0462] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a second value (for example, the codepoint is "01"), the third PUSCH corresponds to a fourth SRS resource.

[0463] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a third value (for example, the codepoint is "10"), then the third PUSCH corresponds to a third SRS resource and a fourth SRS resource, where the third SRS resource is determined by the "SRS resource indicator" indication field in the second DCI, and the fourth SRS resource is determined by the "Second SRS resource indicator" indication field in the second DCI.

[0464] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRS resource set indicator indication field in the second DCI indicates a fourth value (for example, the codepoint is "11"), then the third PUSCH corresponds to a third SRS resource and a fourth SRS resource, where the third SRS resource is determined by the "SRS resource indicator" indication field in the second DCI, and the fourth SRS resource is determined by the "Second SRS resource indicator" indication field in the second DCI.

[0465] Therefore, the SRS resources corresponding to the third PUSCH can be determined based on the SRS resource set indication field in the second DCI, thereby increasing the flexibility of the system.

[0466] In some implementations of Example 3, if the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, the third SRS resource is associated with the first TCI state among the K1 TCI states, and the fourth SRS resource is associated with the second TCI state among the K1 TCI states. Therefore, the SRS resource can be directly associated with the TCI state, reducing the number of association levels and association complexity.

[0467] In some implementations of Example 3, if the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, the third SRS resource belongs to the first SRS resource set, the fourth SRS resource belongs to the second SRS resource set, the first SRS resource set is associated with a first TCI state among the K1 TCI states, and the second SRS resource set is associated with a second TCI state among the K1 TCI states, then the third SRS resource is associated with the first TCI state, and the fourth SRS resource is associated with the second TCI state. Therefore, the association between the SRS resource set and the TCI state can be utilized to maintain consistency in processing under different PUSCH modes, thereby reducing protocol complexity.

[0468] In some implementations of Example 3, if the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, the third SRS resource belongs to the second SRS resource set, the fourth SRS resource belongs to the first SRS resource set, the first SRS resource set is associated with a first TCI state among the K1 TCI states, and the second SRS resource set is associated with a second TCI state among the K1 TCI states, then the third SRS resource is associated with the second TCI state, and the fourth SRS resource is associated with the first TCI state. Therefore, the association between the SRS resource set and the TCI state can be utilized to maintain consistency in processing under different PUSCH modes, thereby reducing protocol complexity.

[0469] In some implementations of Example 3, when the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the third PUSCH and the transmission of the third PUSCH based on the first TCI state, the third SRS resource, the second TCI state and the fourth SRS resource.

[0470] In some implementations of Embodiment 3, if the third PUSCH corresponds to the third SRS resource, the third SRS resource is associated with a first TCI state among the K1 TCI states.

[0471] In some implementations of Example 3, if the third PUSCH corresponds to the third SRS resource, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the third PUSCH and the transmission of the third PUSCH based on the first TCI state and the third SRS resource.

[0472] In some implementations of Example 3, when K1=1 and the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the third PUSCH and the transmission of the third PUSCH based on the third SRS resource and the K1=1 TCI state.

[0473] In some implementations of Example 3, when K1=1 and the third PUSCH corresponds to the third SRS resource and the fourth SRS resource, the terminal device determines the uplink transmit spatial filter or spatial relationship corresponding to the third PUSCH and the transmission of the third PUSCH based on the fourth SRS resource and the K1=1 TCI state.

[0474] In some implementations of Example 3, if the third PUSCH needs to be repeatedly transmitted M times (for example, the third PUSCH may be transmitted in M ​​consecutive time slots; for another example, the third PUSCH may have M nominal repetitions).

[0475] In some implementations, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, the SRS resource set indicator field in DCI format 0_1 ​​or DCI format 0_2 indicates a first value (for example, the codepoint is "00"), and the first SRS resource set and the corresponding first TCI state are used for M repeated transmissions of the third PUSCH.

[0476] In some implementations, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, the SRS resource set indicator field in DCI format 0_1 ​​or DCI format 0_2 indicates a second value (for example, the codepoint is "01"), and the second SRS resource set and the corresponding second TCI state are used for M repeated transmissions of the third PUSCH.

[0477] In some implementations, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, when the SRS resource set indicator indication field in DCI format 0_1 ​​or DCI format 0_2 indicates a third value (for example, codepoint is "10"), it can be divided into the following cases based on the value of M:

[0478] When M=2, the first SRS resource set and the corresponding first TCI state are used for the first transmission of the third PUSCH (for example, the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), and the second SRS resource set and the corresponding second TCI state are used for the second transmission of the third PUSCH (for example, the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions).

[0479] When M>2, if RRC IE PUSCH-Config indicates cyclic mapping (i.e., cyclic Mapping is enabled), the first SRS resource set and the corresponding first TCI state are used for the first transmission of the third PUSCH (e.g., the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), the second SRS resource set and the corresponding second TCI state are used for the second transmission of the third PUSCH (e.g., the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions), and the same mapping pattern is repeated in sequence until a total of M transmissions are completed (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 4th repeated transmissions, the corresponding SRS resource sets are: the first SRS resource set, the second SRS resource set, the first SRS resource set, and the second SRS resource set, respectively.

[0480] When M>2, if RRC IE PUSCH-Config indicates sequential mapping (i.e., sequential Mapping is enabled), the first SRS resource set and the corresponding first TCI state are used for the first and second transmissions of the third PUSCH (e.g., the first and second slots in M ​​consecutive slots, or the first and second retransmissions in M ​​nominal retransmissions), the second SRS resource set and the corresponding second TCI state are used for the third and fourth transmissions of the third PUSCH (e.g., the third and fourth slots in M ​​consecutive slots, or the third and fourth retransmissions in M ​​nominal retransmissions), and the same subsequent mapping pattern is repeated until a total of M transmissions are completed (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 8th repeated transmissions, the corresponding SRS resource sets are: the first SRS resource set, the first SRS resource set, the second SRS resource set, the second SRS resource set, the first SRS resource set, the first SRS resource set, the second SRS resource set, and the second SRS resource set.

[0481] In some implementations, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, when the SRS resource set indicator indication field in DCI format 0_1 ​​or DCI format 0_2 indicates the fourth value (for example, codepoint is "11"), it can be divided into the following cases based on the value of M:

[0482] When M=2, the second SRS resource set and the corresponding second TCI state are used for the first transmission of the third PUSCH (for example, the first slot in M ​​consecutive slots, or the first retransmission in M ​​nominal retransmissions), and the first SRS resource set and the corresponding first TCI state are used for the second transmission of the third PUSCH (for example, the second slot in M ​​consecutive slots, or the second retransmission in M ​​nominal retransmissions).

[0483] When M>2, if the RRC IE PUSCH-Config indicates cyclicMapping (i.e., cyclicMapping is enabled), the second SRS resource set and the corresponding second TCI state are used for the first transmission of the third PUSCH, the first SRS resource set and the corresponding first TCI state are used for the second transmission of the third PUSCH, and the same mapping pattern is repeated in sequence until a total of M transmissions are made (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 4th repeated transmissions, the corresponding SRS resource sets are: the second SRS resource set, the first SRS resource set, the second SRS resource set, and the first SRS resource set.

[0484] When M>2, if RRC IE PUSCH-Config indicates sequentialMapping (i.e., sequentialMapping is enabled), the second SRS resource set and the corresponding second TCI state are used for the first and second transmissions of the third PUSCH, and the first SRS resource set and the corresponding first TCI state are used for the third and fourth transmissions of the third PUSCH. The same mapping pattern is repeated in sequence until a total of M transmissions are made (the same mapping pattern continues to the remaining slots of the M consecutive slots). For example, for the 1st to 8th repeated transmissions, the corresponding SRS resource sets are: second SRS resource set, second SRS resource set, first SRS resource set, first SRS resource set, second SRS resource set, second SRS resource set, first SRS resource set, and first SRS resource set.

[0485] The above solution can be used in the case where K1=2 TCI states. It can also be used in the case where K1=1 TCI state. In this case, the first TCI state and the second TCI state are the same TCI state, referring to the K1=1 TCI state, and the third SRS resource and the fourth SRS resource are used to determine the transmission of the third PUSCH.

[0486] For the case where K1=1 TCI state, there may also be another solution.

[0487] For example, only the third SRS resource and the K1=1 TCI state are used to transmit the third PUSCH. For example, the third SRS resource and the K1=1 TCI state are used to transmit the third PUSCH M times. Therefore, only one SRS resource can be used, reducing product implementation complexity.

[0488] For another example, only the fourth SRS resource and K1=1 TCI state are used to transmit the third PUSCH. For example, the fourth SRS resource and the K1=1 TCI state are used to transmit the third PUSCH M times. Therefore, only one SRS resource can be used, reducing product implementation complexity.

[0489] Optionally, the first SRS resource set corresponds to the "SRS resource indicator" indication field in the second DCI, and the second SRS resource set corresponds to the "Second SRS resource indicator" indication field in the second DCI. For example, the SRI indicated by the "SRS resource indicator" indication field in the second DCI corresponds to an SRS resource in the first SRS resource set, and the SRI indicated by the "Second SRS resource indicator" indication field in the second DCI corresponds to an SRS resource in the second SRS resource set.

[0490] In some implementations of Example 3, a terminal device receives fourteenth indication information sent by a network device, where the fourteenth indication information indicates that, in a single transmission of the third PUSCH, transmission of the third PUSCH is determined based on both the first TCI state and the second TCI state. For example, based on the fourteenth indication information, the terminal device determines, in each PUSCH transmission in CG PUSCH type 2 (if there are multiple transmissions), an uplink transmit spatial filter or spatial relationship corresponding to the third PUSCH based on both the first TCI state and the second TCI state.

[0491] Optionally, the fourteenth indication information may be carried by one of the following: RRC signaling, MAC CE, or DCI signaling.

[0492] Optionally, the fourteenth indication information is configured for BWP, that is, the configuration granularity of the fourteenth indication information is BWP.

[0493] Optionally, the fourteenth indication information is for the first configuration authorization configuration, that is, the configuration granularity of the fourteenth indication information is configuration authorization configuration.

[0494] Optionally, the fourteenth indication information is configured through the RRC parameter configuredGrantConfig.

[0495] Optionally, the thirteenth indication information and the fourteenth indication information correspond to the same RRC parameter.

[0496] In some embodiments, the terminal device determines uplink transmission based on the first SRS resource set and / or the second SRS resource set determined according to the above scheme, and the TCI state corresponding to each SRS resource set (for example, the first TCI state and / or the second TCI state).
