[0059] In an embodiment of the present application, the “protocol” may refer to a standard protocol in the communication 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.

[0060] 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 arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0061] In order to facilitate a better understanding of the embodiments of the present application, a multi-beam system related to the present application is described.

[0062] The design goals of NR systems or 5G systems include large bandwidth communications in high frequency bands (e.g., bands above 6 GHz). When the operating frequency becomes higher, the path loss during transmission will increase, thus affecting the coverage capability of the high frequency system. In order to effectively ensure the coverage of high frequency band NR systems, an effective technical solution is to use multiple beams (or hybrid beams) based on massive antenna arrays (such as multiple input multiple outputs (MIMO)) to improve coverage.

[0063] In a typical system, a cell (sector) uses a wider beam to cover the entire cell, so at every moment, UEs within the cell coverage area have the opportunity to obtain transmission resources allocated by the system.

[0064] The multi-beam system of the NR system or 5G system covers the entire cell through different beams, that is, each beam covers a smaller area, and the effect of multiple beams covering the entire cell is achieved through time scanning. Currently, different beams are identified by the different signals carried on them.

[0065] Different synchronization signal blocks (SSB) are transmitted on different beams, and UE can distinguish different beams through different SSBs. SSB can also be called synchronization signal / physical broadcast channel block (SS / PBCH block).

[0066] 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.

[0067] 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.

[0068] 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 transmit beams of the base station.

[0069] For millimeter wave systems, there may be analog beams on the UE side, and the corresponding downlink receive beam needs to be used to receive the signal sent by the corresponding downlink transmit beam. At this time, corresponding beam indication information is required to assist the UE in determining the transmit beam related information on the network side, or the corresponding receive beam related information on the UE side.

[0070] In the NR protocol, the beam indication information does not directly indicate the beam itself, but is indicated by the quasi-co-located (QCL) type between signals (such as QCL type D (QCL-TypeD)). 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 indication (TCI) state through relevant signaling (Radio Resource Control (RRC), and / or, Media Access Control Control Element (MAC CE), and / or, Downlink Control Information (DCI)).

[0071] In order to facilitate a better understanding of the embodiments of the present application, the multiple transmission reception points (TRP) / antenna panels (panels) / beam transmissions related to the present application are explained.

[0072] Multiple TRP (mTRP or M-TRP) transmission means that multiple TRPs can communicate with a terminal at the same time on the same carrier. In the NR system, multiple TRP transmissions, or multiple panels or multiple beams transmitting to a terminal at the same time, can use the same solution. Therefore, in the description, they are often not distinguished (for example, called multiple TRP transmission, mTRP transmission, or M-TRP transmission), or expressed as multiple TRP / panel / beam transmission.

[0073] The solution of transmitting downlink data to UE by multiple TRPs or multiple antenna panels or multiple beams simultaneously supports the following two types of solutions:

[0074] Solution 1: single-PDCCH based scheme, the UE detects only one PDCCH, and the DCI detected on this control channel PDCCH indicates the relevant indication information of the data transmitted simultaneously on multiple TRPs / panels / beams (from the protocol level, it is not possible to see multiple TRPs / panels / beams, but only that one transmission needs to correspond to multiple TCI-states, that is, multiple TRPs / panels / beam transmissions are implicitly supported through multiple TCI-states).

[0075] 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 possible to see multiple TRPs / panels / beams, only that the control resource set (CORESET) corresponding to the DCI of the scheduling data may be associated with different CORESET pool indexes, that is, corresponding to different CORESET pool indexes, that is, multiple TRP / panel / beam transmissions are implicitly supported through multiple different CORESET pool indexes).

[0076] Specifically, multiple TRP transmissions can be as follows Figure 2 As shown, multiple beam transmissions can be Figure 3 shown.

[0077] 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.

[0078] For solution 2, the UE needs to detect multiple PDCCHs on the same carrier at the same time, which may increase the complexity, but the flexibility and robustness may be improved.

[0079] The possible application scenarios of Solution 2 include at least one of the following:

[0080] S1-1: Multiple TRPs belong to the same cell, and the connection (backhaul) between TRPs is ideal (i.e., fast and dynamic information exchange is possible);

[0081] 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);

[0082] S1-3: Multiple TRPs belong to different cells, and the connection (backhaul) between TRPs is ideal;

[0083] S1-4: Multiple TRPs belong to different cells, and the connection (backhaul) between TRPs is not ideal;

[0084] S2-1, S2-2, S2-3, S2-4: Replace the TRP in the above with beam, and you can get four multi-beam application scenarios.

[0085] Solution 1 is generally considered to be only applicable to ideal backhaul scenarios (ie, S1-1 and S1-3).

[0086] In release 16 (R16), multiple TRP transmission of downlink data transmission is supported. In release 17 (R17), multiple TRP transmission of physical downlink control channel (PDCCH), physical uplink shared channel (PUSCH), and physical uplink control channel (PUCCH) is supported to increase the reliability of corresponding channel transmission.

[0087] The sounding reference signal (SRS) resources used when PUSCH is transmitted to two TRPs and the precoding matrix used when the codebook is transmitted may be different to match the channel states of different TRPs respectively. Therefore, single DCI scheduling (for PUSCH dynamically scheduled by DCI) supports the use of one DCI to indicate two SRS resource indicators (SRSresource indicator, SRI) / transmit precoding matrix indicators (Transmit Precoding Matrix Indicator, TPMI), that is, based on two independent SRI domains and two independent TPMI domains to indicate the PUSCH corresponding to the two TRPs.

[0088] 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), where Type 1 CG PUSCH is semi-statically configured by RRC, including time-frequency domain resources, demodulation reference signal (Demodulation Reference Signal, DMRS), open-loop power control, modulation and coding scheme (Modulation and Coding Scheme, MCS) and other parameters required for PUSCH transmission, while Type 2 CG PUSCH is configured by RRC with some semi-static parameters including the period of time-domain resources, power control, number of repetitions, etc., which are activated by DCI and indicate time-frequency resources, DMRS, MCS and other parameters in the same DCI. In R17, both CG PUSCHs are enhanced based on multiple TRPs. R17 stipulates that a set of P0-PUSCH-Alpha and power control loop (powerControlLoopToUse) are added to the CG configuration (ConfiguredGrantConfig) for power control of the second TRP. For Type2 CG PUSCH, the original first set of power control values ​​are associated with the first SRS resource set, and the second set of values ​​are associated with the second SRS resource set. The use of the first set of power control or the second set of power control or the use of the first and second sets of power control depends on the newly added 2-bit field in the DCI to indicate the dynamic switching of single TRP and multiple TRPs. For Type1 CG PUSCH, a set of path loss reference index (pathlossReferenceIndex) field, SRS resource indication (srs-ResourceIndicator) field, precoding and number of layers (precodingAndNumberOfLayers) field are added to the RRC configuration uplink grant (rrc-ConfiguredUplinkGrant) to indicate the path loss reference signal corresponding to the second TRP, SRI and TPMI.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 have the same number of bits as the srs-ResourceIndicator field and precodingAndNumberOfLayers field associated with the first SRS resource set.

[0089] It should be noted that configuration grant (CG) can also be called: scheduling-free or dynamic scheduling-free.

[0090] It should be noted that for the multi-TRP system, the transmission schemes discussed above are all for the case of the same carrier. For example, for the multiple-PDCCH based scheme, the terminal detects multiple DCIs on the same carrier (the existing protocol supports 2), where each DCI can schedule the corresponding PDSCH, and multiple PDSCHs are also on the same carrier or the same cell. The same is true for uplink multi-TRP transmission, which is for transmission on the same carrier.

[0091] In order to facilitate a better understanding of the embodiments of the present application, the TCI state related to the present application is explained.

[0092] When receiving signals, the terminal can improve the reception performance by using the characteristics of the transmission environment corresponding to the data transmission to improve the reception algorithm. For example, the statistical characteristics of the channel can be used to optimize the design and parameters of the channel estimator. In the NR system, these characteristics corresponding to the data transmission are represented by Quasi-co-located (QCL) information (QCL-Info).

[0093] 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.

[0094] A TCI state can contain the following configurations:

[0095] TCI state identification (Identity, ID), used to identify a TCI state;

[0096] QCL information 1;

[0097] QCL information 2 (optional).

[0098] Among them, a QCL information contains the following information:

[0099] QCL type configuration, which can be one of QCL type A, QCL type B, QCL type C, or QCL type D;

[0100] 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 identifier of the reference signal (which can be a CSI-RS resource ID or SSB index).

[0101] 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, typeC, and the QCL type of the other QCL information (if configured) must be QCL type D.

[0102] Among them, the definitions of different QCL type configurations are as follows:

[0103] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0104] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0105] 'QCL-TypeC':{Doppler shift, average delay};

[0106] 'QCL-TypeD':{Spatial Rx parameter}.

[0107] For example, the semantic fields of the TCI status may be described as follows.

[0108]

[0109] In the NR system, the network side can indicate the corresponding TCI status for the downlink signal or downlink channel.

[0110] If the network side configures the QCL reference signal of the target downlink channel or the target downlink signal as a reference SSB or a 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 large-scale parameters of the target downlink signal and the reference SSB or reference CSI-RS resource are the same, and the large-scale parameters are determined by the QCL type configuration.

[0111] 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, the same panel, or the same beam on the network side. If the transmission TRP, transmission panel, or transmission beam of two downlink signals or downlink channels is different, different TCI states are usually configured.

[0112] For the downlink control channel, the TCI status of the corresponding CORESET can be indicated by RRC signaling or RRC signaling + MAC signaling.

[0113] For downlink data channels, 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, the TCI state indication field in the DCI indicates one or two TCI states from the activated TCI states for the PDSCH scheduled by the DCI. The case of two TCI states is mainly for scenarios with multiple TRPs. For example, Figure 4 As shown, 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.

[0114] In order to facilitate a better understanding of the embodiments of the present application, the unified TCI state (Unified TCI state) related to the present application is explained.

[0115] The TCI status indication mechanism is only applicable to downlink channels and signals, and has many limitations in its application in NR systems. In order to provide a more unified uplink and downlink beam management mechanism for the NR system, a unified TCI status concept is proposed. Examples of the important new functions added are as follows:

[0116] Two unified TCI status modes are designed, namely Mode 1 and Mode 2 as follows;

[0117] Downlink channels (partial PDCCH, PDSCH) and signals (aperiodic CSI-RS) use the same downlink transmit indicator beam, using downlink TCI state or joint TCI state. This type of TCI state is called separate TCI state;

[0118] 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;

[0119] Unified TCI state can be dynamically updated and indicated using MAC CE and / or DCI;

[0120] Applicable to the scenario of carrier aggregation, the beam indication on a single component carrier (CC) can be applied to multiple different CCs;

[0121] The uplink beam indication can be given together with the uplink power control parameters through UL TCI state or joint TCIstate;

[0122] Supports inter-cell beam management function.

[0123] Mode 1: includes 1 type of TCI state, which can be applied to uplink and downlink channels and signals; this type of TCI state is called a joint TCI state.

[0124] Mode 2: includes two types of TCI states, where the DL TCI state is only applicable to downlink channels and signals; the UL TCI state is only applicable to uplink channels and signals.

[0125] For each CORESET on CC, it can be roughly divided into the following four types:

[0126] CORESET A: is associated only with the UE-specific search space, so it can be considered as a UE-specific downlink control channel resource and must follow the indicated unified TCI state;

[0127] CORESET B: only associated with the common search space of the cell. Whether it can follow the unified TCI state indicated by the NW depends on the RRC configuration of the network device.

[0128] CORESET C: Associated with 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.

[0129] CORESET 0: It must be associated with the common search space of the cell, and can also be associated with the UE-specific search space at the same time. Whether it can follow the unified TCI state indicated by the network device depends on the RRC configuration of the network device.

[0130] At present, in the unified TCI state mechanism, the scenario of multi-TRP transmission is not considered, and only the scenario of single TRP is supported.

[0131] It should be noted that when referring to TCI state, if it is not clearly specified which TCI state it is, 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 of them (that is, including multiple different types of TCI states). If the RRC parameter TCI-State is used (there is a connecting symbol 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.

[0132] In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application are explained.

[0133] 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.

[0134] Based on the above problems, the present 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).

[0135] The technical solution of the present application is described in detail below through specific embodiments.

[0136] Figure 5 is a schematic flow chart of a wireless communication method 200 according to an embodiment of the present application, such as Figure 5 As shown, the wireless communication method 200 may include at least part of the following contents:

[0137] S210, the network device sends first indication information, the first indication information is used to indicate a first SRS resource set and a second SRS resource set, the first SRS resource set and the second SRS resource set are used for PUSCH based on a codebook (Codebook based) or based on a non-codebook (Non-Codebook based); 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, part 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;

[0138] S220, the terminal device receives the first indication information.

[0139] 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, part 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 part 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.

[0140] 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.

[0141] 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.

[0142] In some embodiments, a TCI state among the K1 TCI states is a joint TCI state (joint TCI state), or a TCI state among the K1 TCI states is an uplink TCI state (uplink TCI state).

[0143] 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, that is, the TCI state in 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, that is, the TCI state in the K1 TCI states is an uplink TCI state.

[0144] In some embodiments, the first indication information may be carried by one of the following: RRC signaling, DCI signaling, or MACCE signaling.

[0145] 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 (SRS resource sets). For example, the SRS resource set with a smaller ID among the two SRS resource sets is the first SRS resource set, and the SRS resource set with a larger ID is the second SRS resource set. For another example, the SRS resource set with a larger ID among the two SRS resource sets is the first SRS resource set, and the SRS resource set with a smaller ID is the second SRS resource set.

[0146] In some embodiments, the usage of the first SRS resource set and the second SRS resource set are both for codebook-based or non-codebook-based 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 set to "codebook" or "nonCodebook".

[0147] 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).

[0148] 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.

[0149] For example, the first parameter or the second parameter is configured in the configuration signaling corresponding to the first SRS resource set; or, the first parameter in the configuration signaling corresponding to the first SRS resource set is enabled (enabled), or, the second parameter in the configuration signaling corresponding to the first SRS resource set is enabled (enabled). The first parameter is: follow the unified TCI state SRS (followUnifiedTCIstateSRS), and the second parameter is: follow the unified TCI state (followUnifiedTCIstate).

[0150] For example, the first parameter or the second parameter is configured in the configuration signaling corresponding to the second SRS resource set; 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: follow the unified TCI state SRS (followUnifiedTCIstateSRS), and the second parameter is: follow the unified TCI state (followUnifiedTCIstate).

[0151] For example, the semantic fields of followUnifiedTCIstateSRS being enabled may be as follows:

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.

[0154] 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 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 a TCI state. That is, when K1=1, 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 a TCI state.

[0155] 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.

[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, 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.

[0157] 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.

[0178] Specifically, the TCI state type indication field in 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.

[0187] Among them, when the maximum number is 48, it supports up to 4 downlink TRP transmissions and 2 uplink TRP transmissions, which improves the downlink transmission performance, improves the flexibility of network configuration and scheduling, and also controls the UE implementation complexity within a certain range.

[0188] 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 the flexibility of network configuration and scheduling at the cost of UE implementation complexity.

[0189] In some embodiments, when K1>1, the first TCI state is determined based on the TCI state identifier in the K1 TCI states, and / or the second TCI state is determined based on the TCI state identifier in 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 TCI state identifier), which can effectively reduce the complexity of product implementation.

[0190] Specifically, 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.

[0191] 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.

[0192] 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.

[0193] 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 the indication information sent by the network device at least for indicating or activating the TCI state, and the TCI state indicated or activated by the second indication information includes 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 the preset rule (i.e., the position information of the K1 TCI states in the second indication information), which can effectively reduce the complexity of product implementation.

[0194] 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.

[0195] As another specific 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.

[0196] In some embodiments, when K1>1, the first TCI state is indicated by the network device through the third indication information, and / or the second TCI state is indicated by the network device through the fourth indication information. That is, the network device may indicate the first TCI state among the K1 TCI states through the third indication information, and / or the network device may indicate the second TCI state among the K1 TCI states through the fourth indication information.

[0197] 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 most forward 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 most backward position among the K1 TCI states in the second indication information; wherein the second indication information is the indication information sent by the network device at least for indicating or activating the TCI state, and the TCI state indicated or activated by the second indication information includes 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, and the signaling overhead can be reduced.

[0198] 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 most forward 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 most backward position among the K1 TCI states in the second indication information; wherein the second indication information is the indication information sent by the network device at least for indicating or activating the TCI state, and the TCI state indicated or activated by the second indication information includes 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, and the signaling overhead can be reduced.

[0199] Specifically, 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.

[0200] 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.

[0201] For example, the third indication information is used to indicate that the first TCI state is the TCI state with the earliest position among 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 K1 TCI states in the second indication information.

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

[0203] 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 smallest 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 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, which can reduce signaling overhead.

[0204] 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, which can reduce signaling overhead.

[0205] In some embodiments, when the terminal device does not obtain the fourth indication information, or when 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, when the terminal device obtains the fourth indication information, or when 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, which can reduce signaling overhead.

[0206] In some embodiments, when the terminal device does not obtain the fourth indication information, or when 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, when the terminal device obtains the fourth indication information, or when 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, which can reduce signaling overhead.

[0207] For 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 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 has obtained 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.

[0208] 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 has obtained 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.

[0209] In some embodiments, when the third indication information is the 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 is the 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, and the signaling structure is flexible, which is convenient for future expansion to the case where K1>2.

[0210] In some embodiments, when the third indication information is the first value, the first TCI state is the TCI state with the largest identifier among the K1 TCI states; and / or, when the third indication information is the second value, 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 the third indication information, and the signaling structure is flexible, which is convenient for future expansion to the case where K1>2.

[0211] In some embodiments, when the fourth indication information is the 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 is the 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, and the signaling structure is flexible, which is convenient for future expansion to the case where K1>2.

[0212] In some embodiments, when the fourth indication information is 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 is 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, and the signaling structure is flexible, which is convenient for future expansion to the case where K1>2.

[0213] 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.

[0214] As 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.

[0215] 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.

[0216] 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.

[0217] 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 TCIstate that is 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 TCIstate that is closest to the back in the second indication information among K1=2 TCI states.

[0218] 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 TCIstate that is 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 TCIstate that is closest to the back in the second indication information among K1=2 TCI states.

[0219] 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.

[0220] 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.

[0221] 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.

[0222] 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 / or the uplink transmit spatial filter or spatial relationship corresponding to the second SRS resource set is determined based on the second TCI state.

[0223] In some embodiments, when K1>1, the 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.

[0224] In some embodiments, when the TCI state among 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 in the first TCI state and the first SRS resource set.

[0225] In some embodiments, when a 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.

[0226] In some embodiments, when K1>1, the 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.

[0227] 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 in the second TCI state and the second SRS resource set.

[0228] In some embodiments, when a 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.

[0229] In some embodiments, when K1=1, the uplink transmission spatial filters or spatial relationships corresponding to the first SRS resource set and the second SRS resource set are 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 transmission spatial filters or spatial relationships corresponding to the first SRS resource set and the second SRS resource set are determined based on the first TCI state.

[0230] 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 the current PUSCH transmission does not consider the second SRS resource set. 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 the TCI state, the uplink transmission 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.

[0231] In some embodiments, when K1=1, the uplink transmission 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 transmission 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.

[0232] In some embodiments, the uplink transmission 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. 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 the TCI state, the uplink transmission 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.

[0233] In some embodiments, the K1 TCI states belong to N TCI states;

[0234] 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.

[0235] 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.

[0236] For example, K1 TCI states among the N TCI states are used for uplink transmission, and K2 TCI states among the N TCI states are used for downlink transmission. Wherein, 0<=K1<=N, 0<=K2<=N. For example, K1=K2, or, N=K1 and K2=0, or other combinations.

[0237] 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.

[0238] In some embodiments, the K1 TCI states are indicated by the network device through the fifth indication information. In other words, the network device can indicate the K1 TCI states among the N TCI states through the fifth indication information. Therefore, in this embodiment, by introducing new indication information (i.e., the fifth indication information), the uplink and downlink can be independently configured with multi-TRP (M-TRP) transmission, which reduces the complexity of terminal implementation and facilitates more types of terminals to support this function.

[0239] In some embodiments, the fifth indication information is carried by one of the following: RRC signaling, MAC CE signaling, and DCI signaling.

[0240] It should be noted that RRC has good reliability but large latency; DCI has small latency and small signaling overhead, but poor reliability; MAC CE has better reliability than DCI, and both signaling overhead and latency are smaller than RRC.

[0241] In some embodiments, the fifth indication information is used to indicate that the K1 TCI states are K1 TCI states selected from the N TCI states in sequence according to the first order. Therefore, in this embodiment, the K1 TCI states selected from the N TCI states according to the preset rule (i.e., the first order) can effectively reduce the complexity of product implementation.

[0242] In some embodiments, the first order is the order of TCI status identifiers from small to large, or the first order is the order of TCI status identifiers from large to small. Of course, the first order can also be other types of orders, for example, the order of odd-numbered TCI status identifiers from small to large, or the order of even-numbered TCI status identifiers from small to large, which is not limited in the present application.

[0243] Specifically, 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.

[0244] Specifically, 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 descending order of TCI state identifiers.

[0245] In some embodiments, the first order may be agreed upon by a protocol, or the first order may be configured by a network device.

[0246] In some embodiments, the fifth indication information is used to indicate that the K1 TCI states are K1 TCI states selected in sequence according to the position order of the N TCI states in the second indication information; wherein the second indication information is indication information sent by the network device at least for indicating or activating the TCI state, and the TCI state indicated or activated by the second indication information includes 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), which can effectively reduce the complexity of product implementation.

[0247] 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.

[0248] 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 in the order of the positions of the N TCI states in the second indication information.

[0249] 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 in the order of the positions of the N TCI states in the second indication information.

[0250] In some embodiments, the N TCI states are indicated by the network device through sixth indication information. 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.

[0251] In some embodiments, the N TCI states are indicated by the network device through the second indication information, wherein the second indication information is the indication information sent by the network device at least for indicating or activating the TCI state, and the TCI state indicated or activated by the second indication information includes 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 sixth indication can be the same indication information.

[0252] In some embodiments, the N TCI states are determined based on the second indication information from the TCI states indicated by the network device through the sixth indication information; wherein the second indication information is indication information sent by the network device at least for indicating or activating the TCI state, and the TCI state indicated or activated by the second indication information includes at least the N TCI states. For example, the network device may indicate multiple TCI states through the sixth indication information, and indicate N TCI states among the multiple TCI states through the second indication information.

[0253] In some embodiments, the sixth indication information is carried by one of the following: RRC signaling, MAC CE signaling, and DCI signaling.

[0254] 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, and the first field is a transmission configuration indication field in the DCI signaling.

[0255] In some embodiments, the terminal device may determine one or more of the following information according to the sixth indication information:

[0256] QCL information corresponding to PDSCH DMRS (Quasi co-location);

[0257] QCL information corresponding to PDCCH DMRS, or QCL information corresponding to DMRS corresponding to some CORESETs;

[0258] QCL information corresponding to at least part of the CSI-RS;

[0259] PUSCH uplink transmit spatial filter (UL TX spatial filter);

[0260] an uplink transmit spatial filter for at least part of the PUCCH;

[0261] A spatial filter for uplink transmission of at least part of the SRS.

[0262] Optionally, an RRC parameter is configured in the SRS resource set (SRS resource set) corresponding to at least part of the SRS: SRS that tracks a unified TCI state in r17 (followUnifiedTCIstateSRS-r17).

[0263] 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.

[0264] 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, DCI is required to additionally indicate which codepoint corresponds to the TCI state to be used as the activated TCI state.

[0265] Optionally, the DCI carrying the sixth indication information is DCI format 1_1 and / or DCI format 1_2, wherein 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).

[0266] 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 may simultaneously schedule data or not schedule downlink transmission (with or without, if applicable, DL assignment), and DCI format 0_1 / 0_2 may simultaneously schedule data or not schedule uplink transmission (with or without, if applicable, UL assignment).

[0267] Optionally, if downlink transmission is not scheduled (without DL assignment), for DCI format 1_1 / 1_2, the terminal device may make the following assumptions (or, DCI format 1_1 / 1_2 satisfies the following conditions):

[0268] The cyclic redundancy check (CRC) of the DCI is scrambled by the configured scheduling radio network temporary identity (CS-RNTI);

[0269] 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 (dynamicSwitch) all set to '0's.

[0270] If at least one TCI state (denoted as TCIstate 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 TCIstate X;), or if at least one TCIstate (denoted as TCIstate X) among the one or more TCI states indicated by the sixth indication information is different from any of the TCIstates 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 select the TCI state X 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 (Hybrid Automatic Repeat request Acknowledgement, HARQ-ACK) information corresponding to the first indication information DCI.

[0271] Some additional examples are given for the above. Take the example that a DCI can indicate up to 2 TCI states for downlink transmission / reception (DL operation, or DL ​​transmission / reception). Other situations (TCI states for uplink, or TCI states for both uplink and downlink) can be similarly expanded. Assume that the network previously indicated TCI state A1 and TCI state A2 for downlink transmission. The signal indicated by the current DCI contains TCI stateX, and TCI state X and TCI state A1 / A2 are different. Then, the above process needs to be considered to determine when TCI stateX can be used (can be applied). For another example, the terminal device currently uses 1 or 2 TCI states (denoted as A1, A2) to determine the QCL information corresponding to the downlink transmission. The signal indicated by the current DCI contains TCI stateX, and TCI state X and TCI state A1 / A2 are different. Then, the above process needs to be considered to determine when TCI stateX can be used (can be applied).

[0272] 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 according to the TCI state, or the corresponding uplink transmission spatial filter is determined. For example, if this TCI state is a UL TCI state, the spatial relationship of the uplink transmission is determined according to the reference signal in this UL TCI state, or the uplink transmission spatial filter. For another example, if the TCI state is a joint TCI state, the spatial relationship of the uplink transmission is determined according to the reference signal corresponding to type D (typeD) in this joint TCI state, or the uplink transmission spatial filter.

[0273] In some embodiments, the terminal device sends first terminal capability information;

[0274] 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 at most 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.

[0275] 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.

[0276] For example, Z1 is 2, or Z1 is 4.

[0277] In some embodiments, the first terminal capability information is reported according to at least one of the following granularities:

[0278] Frequency band granularity, frequency band combination granularity, frequency band granularity in the frequency band combination, carrier granularity on each frequency band in the frequency band combination, frequency band range granularity, terminal granularity.

[0279] For example, the first terminal capability information is reported at a frequency band granularity (per band), that is, the first terminal capability is reported for the frequency band (that is, different frequency bands can independently report corresponding capabilities). Therefore, in this case, different frequency bands are reported independently, which allows the terminal to have greater freedom. For example, the terminal can support this function on one or some frequency bands, but not on other bands, so that more terminals can support this new function.

[0280] For example, the first terminal capability information is reported at a per band combination granularity, that is, the first terminal capability is reported independently according to the band combination. Therefore, in this case, different 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 band combination, but support this function under another band combination, so that more terminals can support this new function.

[0281] For example, the first terminal capability information is reported according to the frequency band granularity (per band per bandcombination) 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 some frequency bands (bands) under another CA combination support this function, so that more terminals can support this new function.

[0282] 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, so that more terminals can support this new function.

[0283] For example, the first terminal capability information is reported according to the frequency range granularity (per frequency range), that is, the first terminal capability is reported according to the frequency range (FR) (that is, different FRs can be reported independently, per FR, that is, FR1 and FR2 are reported independently). Therefore, in this case, different FRs are reported independently, which allows the terminal to have greater freedom. For example, the terminal does not support this function in low frequency (FR1), but supports this function in FR2 (high frequency), so that more terminals can support this new function.

[0284] For example, the first terminal capability information is reported according to the terminal granularity (per UE), that is, the first terminal capability is reported for the UE (i.e., per UE, that is, if the UE reports this capability, then this capability can be supported on all frequency bands). Therefore, in this case, the signaling overhead of the terminal capability reporting is reduced.

[0285] In some embodiments, the first terminal capability information is carried by one of the following: RRC signaling, MAC CE signaling.

[0286] In some embodiments, the terminal device sends second terminal capability information;

[0287] The second terminal capability information is used to indicate that the terminal device supports CG PUSCH.

[0288] In other words, the terminal device can report the second terminal capability information to the network device, so that the network device can determine that the terminal device supports CG PUSCH based on the second terminal capability information.

[0289] In some embodiments, the second terminal capability information is reported according to at least one of the following granularities:

[0290] Frequency band granularity, frequency band combination granularity, frequency band granularity in the frequency band combination, carrier granularity on each frequency band in the frequency band combination, frequency band range granularity, terminal granularity.

[0291] For example, the second terminal capability information is reported at a per-band granularity, that is, the second terminal capability is reported for the band (that is, different bands can independently report corresponding capabilities). Therefore, in this case, different bands are reported independently, which allows the terminal to have greater freedom, for example, the terminal can support this function on one or some bands, but not on other bands, so that more terminals can support this new function.

[0292] For example, the second terminal capability information is reported according to the frequency band combination granularity (per band combination), that is, the second terminal capability is reported independently according to the frequency band combination (band combination). 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 frequency band combination, but support this function under another frequency band combination, so that more terminals can support this new function.

[0293] For example, the second terminal capability information is reported according to the frequency band granularity (per band per bandcombination) 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 some frequency bands (bands) under another CA combination support this function, so that more terminals can support this new function.

[0294] 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 allow the terminal to have greater freedom, so that more terminals can support this new function.

[0295] For example, the second terminal capability information is reported according to the frequency range granularity (per frequency range), that is, the second terminal capability is reported according to the frequency range (FR) (that is, different FRs can be reported independently, per FR, that is, FR1 and FR2 are reported independently). Therefore, in this case, different FRs are reported independently, which allows the terminal to have greater freedom. For example, the terminal does not support this function at low frequency (FR1), but supports this function at FR2 (high frequency), so that more terminals can support this new function.

[0296] For example, the second terminal capability information is reported according to the terminal granularity (per UE), that is, the second terminal capability is reported for the UE (i.e., per UE, that is, if the UE reports this capability, then this capability can be supported on all frequency bands). Therefore, in this case, the signaling overhead of the terminal capability reporting is reduced.

[0297] It should be noted that the reporting granularity of the first terminal capability information and the reporting granularity of the second terminal capability information may be the same or different. For example, the reporting granularity of one terminal capability information is band, and the reporting granularity of another terminal capability information is per CC per band per band combination. Because the uplink and downlink have different requirements for terminal capabilities, using different options for uplink and downlink capabilities can be more conducive to terminal implementation.

[0298] In some embodiments, the second terminal capability information is carried via one of the following: RRC signaling, MAC CE signaling.

[0299] 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.

[0300] In some embodiments, the terminal device sends third terminal capability information;

[0301] 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.

[0302] 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 used for uplink transmission or uplink repeated transmission based on the third terminal capability information.

[0303] For example, Z2 is 2, or Z2 is 4.

[0304] In some embodiments, the third terminal capability information is reported according to at least one of the following granularities:

[0305] Frequency band granularity, frequency band combination granularity, frequency band granularity in the frequency band combination, carrier granularity on each frequency band in the frequency band combination, frequency band range granularity, terminal granularity.

[0306] For example, the third terminal capability information is reported at a per-band granularity, that is, the third terminal capability is reported for the band (that is, different bands can independently report corresponding capabilities). Therefore, in this case, different bands are reported independently, which allows the terminal to have greater freedom, for example, the terminal can support this function on one or some bands, but not on other bands, so that more terminals can support this new function.

[0307] For example, the third terminal capability information is reported at the per band combination granularity, that is, the third terminal capability is reported independently according to the band combination. Therefore, in this case, different 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 band combination, but support this function under another band combination, so that more terminals can support this new function.

[0308] For example, the third terminal capability information is reported according to the frequency band granularity (per band per bandcombination) in the frequency band combination, that is, the third 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 some frequency bands (bands) under another CA combination support this function, so that more terminals can support this new function.

[0309] 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 allow the terminal to have greater freedom, so that more terminals can support this new function.

[0310] For example, the third terminal capability information is reported according to the frequency range granularity (per frequency range), that is, the third terminal capability is reported according to the frequency range (FR) (that is, different FRs can be reported independently, per FR, that is, FR1 and FR2 are reported independently). Therefore, in this case, different FRs are reported independently, which allows the terminal to have greater freedom. For example, the terminal does not support this function in the low frequency (FR1), but supports this function in FR2 (high frequency), so that more terminals can support this new function.

[0311] For example, the third terminal capability information is reported according to the terminal granularity (per UE), that is, the third terminal capability is reported for the UE (i.e. per UE, that is, if the UE reports this capability, then this capability can be supported on all frequency bands). Therefore, in this case, the signaling overhead of the terminal capability reporting is reduced.

[0312] It should be noted that the reporting granularity of the first terminal capability information and the reporting granularity of the third terminal capability information may be the same or different. For example, the reporting granularity of one terminal capability information is band, and the reporting granularity of another terminal capability information is per CC per band per band combination. Because the uplink and downlink have different requirements for terminal capabilities, using different options for uplink and downlink capabilities can be more conducive to terminal implementation.

[0313] In some embodiments, the third terminal capability information is carried via one of the following: RRC signaling, MAC CE signaling.

[0314] Specifically, the difference between the first terminal capability information and the third terminal capability information can be shown by the following example.

[0315] Assume that the terminal device can support two TCI states (denoted as A1 and A2) through the first terminal capability information report. If PUSCH has multiple repeated transmissions, one of the TCI states is used in each PUSCH transmission, but different PUSCH transmissions can use different TCI states. For example, if PUSCH is transmitted four times, the corresponding TCI states may be A1, A2, A1, A2. That is, A1 and A2 are not used in one transmission at the same time, or in other words, A1 and A2 are not used at the same time to determine one PUSCH transmission.

[0316] Assuming that the terminal device can support two TCI states (denoted as A1 and A2) through the third terminal capability information report, if PUSCH has multiple repeated transmissions, then the PUSCH transmission is determined based on these two states (i.e. A1+A2) at each transmission. For example, if PUSCH is repeated 4 times, the corresponding TCI states are A1+A2, A1+A2, A1+A2, and A1+A2.

[0317] The following describes in detail through specific embodiments a scheme for determining the uplink transmit spatial filter or spatial relationship corresponding to the dynamically scheduled PUSCH in the present application (i.e., Embodiment 1), or a scheme for determining the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH (CG PUSCHType1) configured with grant (CG) type 1 (i.e., Embodiment 2), or a scheme for determining the uplink transmit spatial filter or spatial relationship corresponding to the PUSCH (CG PUSCH Type2) configured with grant (CG) type 2 (i.e., Embodiment 3).

[0318] 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 a spatial relationship corresponding to the first PUSCH based on the first information; or, determines an uplink transmit spatial filter or a spatial relationship corresponding to the first PUSCH and the transmission of the first PUSCH based on the first information.

[0319] 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.

[0320] In which, 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.

[0321] Among them, 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.

[0322] In embodiment 1, the terminal device receives the first DCI only after receiving the second indication information and / or the sixth indication information.

[0323] 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.

[0324] 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.

[0325] 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.

[0326] 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.

[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 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.

[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 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.

[0329] In some implementations of Embodiment 1, when K1>1 and the first DCI is DCI format 0_0, the terminal device determines the uplink transmission spatial filter or spatial relationship corresponding to the first PUSCH according to the TCI state indicated by the network device in the first TCI state and the second TCI state. Therefore, in this embodiment, the new indication information is used for flexible configuration, which can increase system flexibility and provide freedom for network optimization.

[0330] 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 transmit spatial filter or spatial relationship corresponding to the first PUSCH based on the eleventh indication information.

[0331] Optionally, the eleventh indication information may be carried by one of the following: RRC signaling, MAC signaling, and DCI signaling.

[0332] Optionally, the eleventh indication information may indicate the 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.

[0333] Optionally, the eleventh indication information may indicate the 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.

[0334] Optionally, the eleventh indication information may indicate the use of the TCI state that is 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.

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

[0336] 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.

[0337] 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.

[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 second SRS resource set and the first TCI state.

[0339] In some implementations of Embodiment 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.

[0340] 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 first value (for example, codepoint is "00"), the first SRS resource set and the corresponding first TCI state are used for M repeated transmissions of the first PUSCH.

[0341] 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.

[0342] 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.

[0343] 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.

[0344] 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").

[0345] 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 among M consecutive slots, or the first retransmission among 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 among M consecutive slots, or the second retransmission among M nominal retransmissions).

[0346] 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 (for example, 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 (for example, 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 (the same mapping pattern continues to theremaining 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.

[0347] 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 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 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.

[0348] 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").

[0349] 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 among M consecutive slots, or the first retransmission among 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 among M consecutive slots, or the second retransmission among M nominal retransmissions).

[0350] Among them, when M>2, if RRC IE PUSCH-Config indicates cyclic Mapping (i.e., 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 (e.g., 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 (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 (the same mapping pattern continues to the remaining slots of the Mconsecutive 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.

[0351] 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 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 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.

[0352] The above solution can be used in the case where K1=2 TCI states or 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, which refers to the K1=1 TCI state.

[0353] 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.

[0354] For another example, only the second SRS resource set and K1=1 TCI state are used to perform the first PUSCH transmission. An example is to use the second SRS resource set and the K1=1 TCI state to perform M repeated transmissions of the first PUSCH.

[0355] 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 format0_2 is restricted, and can only take part of the values, not other parts 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").

[0356] 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.

[0357] In some implementations of Example 1, the terminal device receives twelfth indication information sent by the network device, wherein the twelfth indication information is used to indicate that in a single transmission of the first PUSCH, the transmission of the first PUSCH is determined according to the first TCI state and the second TCI state. For example, according to the twelfth indication information, the terminal device determines the uplink transmission spatial filter or spatial relationship corresponding to the first PUSCH according to the first TCI state and the second TCI state in each transmission of the first PUSCH (if there are multiple transmissions).

[0358] Optionally, the twelfth indication information may be carried by one of the following: RRC signaling, MAC CE signaling, and DCI signaling.

[0359] Optionally, the twelfth indication information may be configured for BWP, that is, the configuration granularity of the twelfth indication information is BWP.

[0360] Optionally, the twelfth indication information is configured through the RRC parameter PUSCH-Config.

[0361] In embodiment 2, the terminal device determines an uplink transmit spatial filter or a spatial relationship corresponding to a second PUSCH and transmission of the second PUSCH according to the second information;

[0362] 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;

[0363] 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.

[0364] In Embodiment 2, the network device may configure one or more configuration grants (ConfiguredGrant Configuration) for the terminal device, for example, one or more configuration grants on one BWP may be configured through RRC signaling. For the convenience of description, one of the configuration grants (the first configuration grant) is taken as an example to introduce the subsequent solution.

[0365] Optionally, the first configured grant is configured grant Type 1.

[0366] 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.

[0367] 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.

[0368] 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.

[0369] Optionally, the network device may also configure one or more of the following information for the first configuration authorization (for example, through RRC signaling):

[0370] Frequency-domain frequency hopping indication information, such as intra-slot hopping and inter-slot hopping;

[0371] Demodulation reference signal (DMRS) indication information;

[0372] Resource allocation indication information, such as time domain and / or frequency domain resource allocation;

[0373] Power control parameter indication information;

[0374] Precoding indication information;

[0375] SRS resource indication information;

[0376] Repeat transmission of indication information;

[0377] Hybrid Automatic Repeat reQuest (HARQ) process indication information.

[0378] In Embodiment 2, the information of the first authorization configuration is used, and the following part or all of the information of pusch-Config in the RRC parameters is also used:

[0379] a. PUSCH data scrambling identity (dataScramblingIdentityPUSCH);

[0380] b. Transmission configuration (txConfig);

[0381] c. codebook subset (codebookSubset);

[0382] d. Maximum rank (maxRank);

[0383] e. Uplink Control Information (UCI) range on PUSCH (scaling of UCI-OnPUSCH).

[0384] In some implementations of Embodiment 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 association level and reducing the association complexity.

[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 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 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, 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 used to maintain consistency in processing under different PUSCH modes and reduce protocol 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 second SRS resource set, the second SRS resource belongs to the first SRS resource set, 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, 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 used to maintain consistency in processing under different PUSCH modes and reduce protocol complexity.

[0387] 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.

[0388] 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.

[0389] 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.

[0390] 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.

[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 second SRS resource and the K1=1 TCI state.

[0392] In some implementations of Embodiment 2, if the second PUSCH needs to be transmitted repeatedly 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).

[0393] Specifically, when M=2, the first SRS resource corresponds to the first transmission of the second PUSCH (for example, the first slot among M consecutive slots, or the first retransmission among M nominal retransmissions), and the second SRS resource corresponds to the second transmission of the second PUSCH (for example, the second slot among M consecutive slots, or the second retransmission among M nominal retransmissions).

[0394] 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 respectively applied to the first and second transmissions of the second PUSCH (for example, the first and second slots in M ​​consecutive slots, or the first and second retransmissions in M ​​nominal retransmissions), and the same mapping pattern is repeated in sequence until a total of M transmissions (the samemapping 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: the first SRS resource, the second SRS resource, the first SRS resource, and the second SRS resource.

[0395] Specifically, when M>2, if the RRC information element (IE) configured grant configuration (ConfiguredGrantConfig) indicates sequential mapping (sequentialMapping) (that is, 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 (for example, 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 (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 patterns are 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 8th repeated transmissions, the corresponding SRS resources are: the first SRS resource, the first SRS resource, the second SRS resource, the second SRS resource, the first SRS resource, the first SRS resource, the first SRS resource, the second SRS resource, and the second SRS resource.

[0396] The above scheme can be used in the case of K1=2 TCI states. It can also be used in the case of K1=1 TCI state, in which 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.

[0397] For the case where K1=1 TCI state, there may also be other solutions.

[0398] For example, only the first SRS resource and K1=1 TCI state are used to perform the second PUSCH transmission. For example, the first SRS resource and K1=1 TCI state are used to perform M repetitions of the second PUSCH transmission. Therefore, only one SRS resource may be used to reduce the complexity of product implementation.

[0399] For another example, only the second SRS resource and K1=1 TCI state are used to perform the second PUSCH transmission. For example, the second SRS resource and K1=1 TCI state are used to perform M repetitions of the second PUSCH transmission. Therefore, only one SRS resource may be used to reduce the complexity of product implementation.

[0400] 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.

[0401] In some implementations of Example 2, the terminal device receives thirteenth indication information sent by the network device, wherein the thirteenth indication information is used to indicate that in a single transmission of the second PUSCH, the transmission of the second PUSCH is determined according to both the first TCI state and the second TCI state. For example, the terminal device determines the uplink transmission spatial filter or spatial relationship corresponding to the second PUSCH according to both the first TCI state and the second TCI state in each PUSCH transmission in CG PUSCH type1 (if there are multiple transmissions) according to the thirteenth indication information.

[0402] Optionally, the thirteenth indication information may be carried by one of the following: RRC signaling, MAC CE, or DCI signaling.

[0403] Optionally, the thirteenth indication information may be configured for BWP, that is, the configuration granularity of the thirteenth indication information is BWP.

[0404] 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.

[0405] Optionally, the thirteenth indication information is configured through the RRC parameter configuredGrantConfig.

[0406] 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 SRS resource of the two SRS resources; and the terminal device can determine the uplink send spatial filter or spatial relationship corresponding to the third PUSCH and the transmission of the third PUSCH according to 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.

[0407] In Embodiment 3, the network device may configure one or more configured grant configurations (ConfiguredGrant Configuration) for the terminal device, for example, one or more configuration grants on one BWP may be configured through RRC signaling. For the convenience of description, one of the configurations (the first configuration) is taken as an example to introduce the subsequent solution.

[0408] Optionally, the first configured grant is a configured grant Type 2.

[0409] Optionally, when the first configuration authorization is configuration authorization type 2, the network device does not include an RRC uplink authorization configuration (rrc-ConfiguredUplinkGrant) in the RRC parameter configuration authorization configuration (configuredGrantConfig) for the first configuration authorization.

[0410] 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.

[0411] 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.

[0412] Optionally, the network device may also configure one or more of the following information for the first configuration authorization (for example, through RRC signaling):

[0413] Frequency-domain frequency hopping indication information, such as intra-slot hopping and inter-slot hopping;

[0414] Demodulation reference signal (DMRS) indication information;

[0415] Resource allocation indication information, such as time domain and / or frequency domain resource allocation;

[0416] Power control parameter indication information;

[0417] Precoding indication information;

[0418] SRS resource indication information;

[0419] Repeat transmission of indication information;

[0420] HARQ process indication information.

[0421] 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:

[0422] Data scrambling identity of PUSCH (dataScramblingIdentityPUSCH);

[0423] Transmission configuration (txConfig);

[0424] codebook subset (codebookSubset);

[0425] Maximum rank (maxRank);

[0426] UCI range on PUSCH (scaling of UCI-OnPUSCH).

[0427] 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:

[0428] Data scrambling identity of PUSCH (dataScramblingIdentityPUSCH);

[0429] Transmission configuration (txConfig);

[0430] Codebook subset DCI-0-2 (codebookSubsetDCI-0-2);

[0431] Maximum rank DCI-0-2 (maxRankDCI-0-2);

[0432] Scaling of UCI-OnPUSCH, resource allocation type 1 granularity DCI-0-2 (resourceAllocationType1GranularityDCI-0-2).

[0433] In embodiment 3, the second DCI may be DCI format 0_0, DCI format 0_1, or DCI format 0_2.

[0434] In embodiment 3, the second DCI satisfies one or more of the following conditions:

[0435] The CRC used by the second DCI is scrambled using the following parameters: the Configured Scheduling Radio Network Temporary Identity (CS-RNTI) configured by the parameter cs-RNTI, or the Group Configured Scheduling Radio Network Temporary Identity (G-CS-RNTI) configured by the parameter g-cs-RNTI;

[0436] The new data indication field in the second DCI is set to 0;

[0437] If the Configured Grant Downlink Feedback Information (CG-DFI) indication field exists in the second DCI, this field is set to 0;

[0438] The time domain resource allocation indication field in the second DCI indicates a row corresponding to one start length indicator value (Start and length indicator value, SLIV) indication.

[0439] Optionally, when there is only one first configuration authorization, the provisions for activating some domains in the DCI of the first configuration authorization are as shown in Table 1.

[0440] Table 1

[0441] 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 blocks: set to all '0's

[0442] Optionally, when there are multiple first configuration authorizations, provisions for activating some domains in the DCI of the first configuration authorization are as shown in Table 2.

[0443] Table 2

[0444] DCI format 0_0 / 0_1 / 0_2 DCI format 1_0 / 1_2 / 4_1 DCI format 1_1 / 4_2 RV Set to all '0's Set to all '0's Enabled transport blocks: set to all '0's

[0445] In some implementations of Embodiment 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, the SRS resource can be determined according to the DCI fixed field using a preset rule, thereby reducing the complexity of product implementation.

[0446] In some implementations of Embodiment 3, when the second DCI is DCI format 0_0, the third PUSCH corresponds to the third SRS resource.

[0447] 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,

[0448] 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,

[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 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,

[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 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.

[0451] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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.

[0452] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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.

[0453] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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, wherein 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.

[0454] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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, wherein 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.

[0455] Therefore, the SRS resources corresponding to the third PUSCH may be determined based on the SRS resource set indication field in the second DCI, thereby increasing the flexibility of the system.

[0456] 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,

[0457] 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,

[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 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,

[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 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.

[0460] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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.

[0461] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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.

[0462] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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, wherein 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.

[0463] Optionally, when the second DCI is DCI format 0_1 ​​or DCI format 0_2, if the SRSresource 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, wherein 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] Therefore, the SRS resources corresponding to the third PUSCH may be determined based on the SRS resource set indication field in the second DCI, thereby increasing the flexibility of the system.

[0465] In some implementations of Embodiment 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 association level and reducing the association complexity.

[0466] In some implementations of Embodiment 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 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, 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 and reduce protocol complexity.

[0467] In some implementations of Embodiment 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 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, 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 and reduce protocol complexity.

[0468] 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.

[0469] In some implementations of Embodiment 3, if the third PUSCH corresponds to the third SRS resource, the third SRS resource is associated with the first TCI state among the K1 TCI states.

[0470] 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.

[0471] 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.

[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 fourth SRS resource and the K1=1 TCI state.

[0473] In some implementations of Embodiment 3, if the third PUSCH needs to be transmitted repeatedly 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).

[0474] 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.

[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 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.

[0476] 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:

[0477] 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 among M consecutive slots, or the first retransmission among 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 among M consecutive slots, or the second retransmission among M nominal retransmissions).

[0478] 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 (the same mapping pattern continues to the remaining slots of the Mconsecutive 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.

[0479] When M>2, if 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 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 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 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.

[0480] 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 fourth value (for example, codepoint is "11"), it can be divided into the following cases based on the value of M:

[0481] 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 among M consecutive slots, or the first retransmission among 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 among M consecutive slots, or the second retransmission among M nominal retransmissions).

[0482] When M>2, if 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 (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.

[0483] 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, the first SRS resource set and the corresponding first TCI state are used for the third and fourth transmissions of the third PUSCH, and the same 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 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.

[0484] The above scheme can be used in the case of K1=2 TCI states. It can also be used in the case of K1=1 TCI state, in which 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.

[0485] For the case where K1=1 TCI state, there may also be other solutions.

[0486] 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 repeatedly. Therefore, only one SRS resource may be used to reduce the complexity of product implementation.

[0487] For another example, only the fourth SRS resource and K1=1 TCI state are used to perform the third PUSCH transmission. For example, the fourth SRS resource and the K1=1 TCI state are used to perform M repetitions of the third PUSCH transmission. Therefore, only one SRS resource may be used to reduce the complexity of product implementation.

[0488] 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.
