It should also be understood that in the embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0044] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. 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.

[0045] The following is a description of the multi-beam system:

[0046] The design goals of the NR / 5G system include high-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 the high-frequency band NR system, an effective technical solution is to use multiple antennas (multiple beam) or hybrid beam (hybrid beam) based on large-scale antenna arrays or multiple input multiple output (MIMO, Massive MIMO) to improve coverage.

[0047] In the existing 2 / 3 / 4G typical system, a cell (sector) uses a wider beam to cover the entire cell. Therefore, at every moment, the terminal devices within the cell coverage have the opportunity to obtain the transmission resources allocated by the system.

[0048] The NR / 5G multi-beam system uses different beams to cover the entire cell, that is, each beam covers a smaller area, and multiple beams cover the entire cell through time sweeping. Currently, different beams are identified by the different signals they carry.

[0049] Optionally, different synchronization signal blocks (SS blocks or SSBs) are transmitted on different beams, and the terminal device can distinguish different beams through different SS blocks. SSB can also be called synchronization signal / physical broadcast channel block (SS / PBCH block).

[0050] Optionally, different channel state information reference signals (CSI-RS) are transmitted on some different beams, and the terminal device identifies different beams through the CSI-RS signals / CSI-RS resources.

[0051] Optionally, these visible signals such as SS blocks and / or CSI-RS may correspond to certain physical beams.

[0052] 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.

[0053] For systems below 6G, there are generally no analog beams on the terminal device side, so omnidirectional antennas (or nearly omnidirectional antennas) are used to receive signals sent by different downlink transmission beams of the base station.

[0054] For millimeter wave systems, there may be analog beams on the terminal device 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 terminal device in determining the transmit beam related information on the network side, or the corresponding receive beam related information on the terminal device side.

[0055] In the NR protocol, the beam indication information does not directly indicate the beam itself, but is indicated through the quasi-co-located (Quasi-co-located or Quasi co-location, QCL) quasi-co-location ('QCL-TypeD' type) between signals. On the terminal device side, the determination of receiving the corresponding channel / signal is also based on the QCL quasi-co-location assumption. The QCL quasi-co-location assumption is indicated by the transmission configuration indication (Transmission Configuration Indication, TCI) state (TCI-state), that is, the network configures and / or indicates the TCI state through relevant signaling (such as Radio Resource Control (Radio Resource Control, RRC), and / or Medium Access Control Control Element (Medium Access Control Control Element, MAC CE), and / or Downlink Control Information (Downlink Control Information, DCI).

[0056] The following is a description of multi-TRP / panel / beam transmission:

[0057] TRP transmission means that multiple TRPs can communicate with a terminal device at the same time on the same carrier. In the NR system, multiple TRP transmissions, or multiple panels or multiple beams can be transmitted to a terminal device at the same time using the same solution. Therefore, they are often not distinguished in the description, such as multi-TRP transmission, multi-TRP (multiple TRP, mTRP) transmission, or M-TRP (Multiple-TRP) transmission, or written as multiple TRP / panel / beam transmission.

[0058] In the related art, the solution of multiple TRPs or multiple panels / antenna panels (Antenna panels) or multiple beams simultaneously transmitting downlink data to terminal devices supports the following two types of solutions:

[0059] Solution 1: single-PDCCH based scheme: The terminal device detects only one NR-PDCCH. The DCI detected in this control channel PDCCH indicates the relevant indication information of the data transmitted simultaneously on multiple TRP / panel / beam. In this way, one transmission corresponds to multiple TCI-states, that is, multiple TRP / panel / beam transmissions are implicitly supported through multiple TCI-states.

[0060] In any embodiment of the present application, TCI-state and TCI state are understood synonymously.

[0061] Solution 2: Multiple-PDCCH based scheme: The terminal device receives different NR-PDCCHs from different TRPs / panels / beams. The DCI detected on each control channel PDCCH indicates relevant indication information of a corresponding data transmission. In this way, the control resource set (COntrolREsource SET, CORESET) corresponding to the DCI of the scheduling data may be associated with different CORESET resource pool numbers / indexes (CORESET poolindex), that is, corresponding to different CORESET pool indexes, that is, multiple TRP / panel / beam transmissions are implicitly supported through multiple different CORESET pool indexes.

[0062] Figure 2 A schematic diagram of a multi-TRP transmission provided in an embodiment of the present application, such as Figure 2 As shown, the terminal device can receive information via TRP1 and / or TRP2.

[0063] Figure 3 A schematic diagram of multiple beam transmission provided in an embodiment of the present application, such as Figure 3 As shown, network devices can send information via beam1 and beam2.

[0064] For the first solution, the terminal device only needs to detect one NR-PDCCH, so the control channel detection complexity may be lower than the second solution. The first solution requires fast information exchange between different panels / TRPs / beams.

[0065] For the second solution, the terminal device needs to detect multiple NR-PDCCHs on the same carrier at the same time. The complexity may increase, but the flexibility and robustness may be improved.

[0066] The possible application scenarios of the second solution include at least the following:

[0067] Scenario 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).

[0068] Scenario 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).

[0069] Scenario 3: Multiple TRPs belong to different cells, and the connection (backhaul) between TRPs is ideal.

[0070] Scenario 4: Multiple TRPs belong to different cells, and the connection (backhaul) between TRPs is non-ideal.

[0071] Scenario 5: Replace TRP in the above scenarios 1-4 with beam, and you can get four multi-beam application scenarios.

[0072] Optionally, the first solution is generally considered to be only applicable to scenarios with ideal backhaul connections (ie, scenarios 1 and 3).

[0073] In R16, only multi-TRP transmission of downlink data transmission is studied and supported. In R17, multi-TRP transmission of downlink control channel (PDCCH), uplink data shared channel (PUSCH), and uplink control channel (PUCCH) is studied and supported to increase the reliability of corresponding channel transmission.

[0074] Different from dynamically scheduled PUSCH (for example, each time PUSCH is dynamically scheduled using DCI), some parameters of scheduling-free / 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 Type1 CG PUSCH and Type2 CG PUSCH, where Type1 CG PUSCH is semi-statically configured by RRC, including time-frequency domain resources, demodulation reference signal (DMRS), open-loop power control, modulation and coding scheme (MCS) and other parameters required for PUSCH transmission, while Type2 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 powerControlLoopToUse is added to the configuration grant configuration (ConfiguredGrantConfig) for power control of the second TRP. For Type2 CG PUSCH, the original first set of power control values ​​is associated with the first channel sounding reference signal (SRS) resource set, and the second set of values ​​is 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 pathlossReferenceIndex field, srs-ResourceIndicator field, and precodingAndNumberOfLayers field are added to rrc-ConfiguredUplinkGrant to indicate the path loss reference signal corresponding to the second TRP, the reference signal resource indicator (SRI) and the precoding matrix indicator (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.

[0075] In any embodiment of the present application, rrc-ConfiguredUplinkGrant can be translated into rrc-configured uplink grant, pathlossReferenceIndex can be translated into path loss reference index, srs-ResourceIndicator can be translated into srs-resource indication, and precodingAndNumberOfLayers can be translated into precoding and number of layers.

[0076] In any embodiment of the present application, configured grant, scheduling-free, and dynamic scheduling-free may be understood as the same, or in other words, configured grant may be configured grant, scheduling-free, or dynamic scheduling-free.

[0077] Grant type 1 PUSCH transmissions are semi-statically configured to operate upon reception of higher layer parameters configured with a configured grant including rrc-ConfiguredUplinkGrant, without detecting a UL grant in the DCI. Grant type 2 PUSCH transmissions are semi-persistently scheduled by a UL grant in a valid activation DCI, upon reception of higher layer parameters configuredGrantConfig that do not include rrc-ConfiguredUplinkGrant.

[0078] For the multi-TRP system, the transmission schemes discussed above are all for the same carrier. For example, for the PDSCH transmission scheme based on multiple PDCCHs (multiple-PDCCH based scheme), the terminal device detects multiple DCIs (for example, 2 DCIs) on the same carrier, where each DCI can schedule the corresponding PDSCH, and multiple PDSCHs are also on the same carrier. PDCCH transmission and / or uplink transmission (for example, PUSCH and / or PDCCH) 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.

[0079] The following is a description of the TCI state:

[0080] When receiving signals, the terminal device 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 the QCL state (QCL-Info).

[0081] 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 device through the TCI state.

[0082] Among them, a TCI state can include the following configurations:

[0083] TCI state ID, used to identify a TCI state;

[0084] QCL information 1;

[0085] QCL Information2.

[0086] Among them, a QCL information contains the following information:

[0087] QCL type configuration, which can be one of QCL type A, QCL type B, QCL type C, QCL type D;

[0088] 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).

[0089] Among them, if QCL information 1 and QCL information 2 are both configured, the QCL type of at least one QCL information is one of typeA, typeB, and typeC, and the QCL type of the other QCL information (if configured) is QCL type D.

[0090] Among them, the definitions of different QCL type configurations are as follows:

[0091] 'QCL-TypeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0092] 'QCL-TypeB': {Doppler shift, Doppler spread};

[0093] 'QCL-TypeC':{Doppler shift, average delay};

[0094] 'QCL-TypeD':{Spatial Rx parameter}.

[0095] In the NR system, the network side can indicate the corresponding TCI status for the downlink signal or downlink channel.

[0096] 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 device 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.

[0097] 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 device 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.

[0098] For the downlink control channel, the TCI state of the corresponding CORESET can be indicated by RRC signaling or RRC signaling + Medium Access Control (MAC) signaling.

[0099] For the downlink data channel, the available TCI state set is indicated by RRC signaling, and some of the TCI states are activated by MAC layer signaling. Finally, one or two TCI states are indicated from the activated TCI states through the TCI state indication field in the DCI for the PDSCH scheduled by the DCI. The case of 2 TCI states is mainly for scenarios similar to multiple TRPs.

[0100] Figure 4 A schematic diagram of a TCI state configuration method for a PDSCH provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, N candidate TCI states can be determined through RRC signaling. For example, RRC signaling can indicate N candidate TCI states. K activated TCI states can be determined from the N candidate TCI states through MAC signaling. One or two used TCI states can be determined from the K activated TCI states through DCI signaling.

[0101] The following is a description of the Unified TCI state:

[0102] The TCI state indication mechanism was introduced in R15 and 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, 3GPP Rel.17 proposed the concept of a unified TCI state based on the design of Rel.15 / 16 TCI state, which adds important new functions, for example:

[0103] Two unified TCI state modes are designed:

[0104] Mode 1: includes 1 type of TCI state, which can be applied to uplink and downlink channels and signals; this type of TCI state can be called a joint TCI state.

[0105] 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.

[0106] Downlink channels (partial PDCCH, PDSCH) and signals (aperiodic CSI-RS) use the same downlink transmission indicator beam and use DL TCI state or joint TCI state.

[0107] Uplink channels (PUCCH, PUSCH) and signals (SRS) use the same uplink transmit beam and use UL TCI state or joint TCI state.

[0108] Unified TCI state can be dynamically updated and indicated using MAC CE and / or DCI.

[0109] The Unified TCI state is applicable to carrier aggregation scenarios, and the beam indication on a single CC can be applicable to multiple different CCs.

[0110] The uplink beam indication can be given simultaneously with the uplink power control parameters through the UL TCI state or joint TCIstate.

[0111] Unified TCI state supports inter-cell beam management.

[0112] For each CORESET on a CC, it can be roughly divided into the following four types in the 3GPP discussion:

[0113] CORESET A: It is only associated with the terminal device-specific search space, so it can be considered as a downlink control channel resource dedicated to the terminal device and must follow the indicated unified TCI state(s);

[0114] CORESET B: It is only associated with the common search space of the cell. Whether it can follow the unified TCI state(s) indicated by the network (NW) depends on the RRC configuration of the NW.

[0115] CORESET C: It is associated with both the terminal device-specific search space and the cell-common search space. Whether it can follow the unified TCI state(s) indicated by the NW depends on the NW RRC configuration;

[0116] CORESET 0: It must be associated with the common search space of the cell, and can also be associated with the terminal device-specific search space at the same time. Whether it can follow the unified TCI state(s) indicated by the NW depends on the RRC configuration of the NW.

[0117] In the unified TCI state mechanism of R17, the scenario of multi-TRP transmission is not considered, and only the scenario of single TRP is supported.

[0118] The TCI state in the embodiment of the present application, if the TCI state is not clearly specified, includes any of the TCI states mentioned above, for example, the TCI state may be a joint TCI state, a separate TCI state, a DL TCI state, a UL TCI state, or a combination thereof (i.e., including multiple different types of TCI states, such as at least one of the DL TCI state, the UL TCI state, the joint TCI state, and the separate TCI state). If the RRC parameter TCI-State is used, it generally refers to the DL TCI state and / or the joint TCI state. If the RRC parameter DLorJointTCIState is used, it generally refers to the DL TCI state and / or the joint TCI state. If the RRC parameter UL-TCIState or TCI-UL-State or UL-TCI-State is used, it generally refers to the UL TCI state.

[0119] However, there is still a lack of complete solutions and specific details on how to configure and indicate the unified TCI state in a multi-TRP transmission system.

[0120] 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.

[0341] In some embodiments, the method further includes: the terminal device receives twelfth information; the twelfth information indicates that the TCI state type includes a joint TCI state or an independent TCI state.

[0342] In some embodiments, the method further includes: the terminal device sends twelfth information; the twelfth information indicates that the TCI state type includes a joint TCI state or an independent TCI state.

[0349] Optionally, at least one of the first capability information, the second capability information, and the third capability information may be capability information of the terminal device.

[0350] In some embodiments, the fourth number is 2 or 4.

[0351] In some embodiments, when the terminal device sends first capability information and second capability information, the first capability information and the second capability information are sent through the same signaling, or the first capability information and the second capability information are sent through different signaling.

[0352] In some embodiments, for the network device side, the network device receives the first capability information and the second capability information through the same signaling, or the network device receives the first capability information and the second capability information through different signaling.

[0353] In some embodiments, at least one of the first capability information, the second capability information, and the third capability information is transmitted via RRC signaling or MAC CE signaling.

[0354] For example, the first capability information is transmitted through RRC signaling or MAC CE signaling. For another example, the second capability information is transmitted through RRC signaling or MAC CE signaling. For another example, the third capability information is transmitted through RRC signaling or MAC CE signaling.

[0355] In some embodiments, at least one of the first capability information, the second capability information, and the third capability information is reported for a frequency band, and / or is independently reported according to a frequency band combination, and / or is independently reported according to each frequency band in the frequency band combination, and / or is independently reported according to each carrier on each frequency band in the frequency band combination, and / or is reported according to a frequency band range, and / or is reported for the terminal device.

[0356] For example, the first capability information is reported for the frequency band, or is reported independently according to the frequency band combination, or is reported independently according to each frequency band in the frequency band combination, or is reported independently according to each carrier on each frequency band in the frequency band combination, or is reported according to the frequency band range, or is reported for the terminal device.

[0357] For example, the second capability information is reported for the frequency band, or is reported independently according to the frequency band combination, or is reported independently according to each frequency band in the frequency band combination, or is reported independently according to each carrier on each frequency band in the frequency band combination, or is reported according to the frequency band range, or is reported for the terminal device.

[0358] For example, the third capability information is reported for the frequency band, or is reported independently according to the frequency band combination, or is reported independently according to each frequency band in the frequency band combination, or is reported independently according to each carrier on each frequency band in the frequency band combination, or is reported according to the frequency band range, or is reported for the terminal device.

[0359] Optionally, the methods of reporting different capability information may be the same or different.

[0360] In some embodiments, the TCI state is a unified TCI state.

[0361] Optionally, the terminal device reports first capability information to the network device, wherein the first capability information indicates that the terminal device supports Z1 (Z>1) unified TCIs for uplink transmission or uplink repeated transmission, or the first capability information indicates that the terminal device supports a codepoint in the Transmission Configuration Indication field in the DCI, which can activate or indicate up to Z1 unified TCIs for uplink transmission.

[0362] Optionally, Z1 is 2, or Z1 is 4.

[0363] Optionally, the first capability information is transmitted via RRC signaling or MAC CE.

[0364] Optionally, the first capability information is reported for a frequency band (i.e., different frequency bands can independently report corresponding capabilities, per band). In this way, different frequency bands can be reported independently, which can allow terminal devices to have greater freedom. For example, a terminal device can support a function on one or some bands, but not on other bands, so that more terminal devices can support this new function.

[0365] Optionally, the first capability information is reported independently according to a band combination (per band combination). In this way, different band combinations are reported independently, which allows the terminal device to have greater freedom. For example, the terminal device may not support this function under a certain band combination, but support this function under another band combination, so that more terminal devices can support this new function.

[0366] Optionally, the first capability information is reported independently for each frequency band in a band combination (i.e., frequency bands in different frequency band combinations can be reported independently, per band per band combination). In this way, different frequency band combinations are reported independently, which allows terminal devices to have greater freedom. For example, a terminal device may not support this function under a certain carrier aggregation (CA), but support this function in certain bands under another CA combination, thereby allowing more terminal devices to support this new function.

[0367] Optionally, the first capability information is reported independently for each carrier on each frequency band in a band combination (i.e., different carriers (Component Carrier, CC) in frequency bands in different frequency band combinations can be reported independently, per CC per band per band combination or feature set per component-carrier (FSPC)). In this way, different frequency band combinations are reported independently, and different carriers on a band can also be reported independently, which allows terminal devices to have greater freedom, so that more terminal devices can support this new function.

[0368] Optionally, the first capability information is reported according to a frequency range (FR) (i.e., different FRs can be reported independently, per FR, i.e., FR1 and FR2 are reported independently). In this way, different FRs are reported independently, which allows the terminal device to have greater freedom. For example, the terminal device does not support this function at low frequency (FR1), but supports this function at FR2 (high frequency), so that more terminal devices can support this new function.

[0369] Optionally, the first capability information is reported for a terminal device (UE) (ie, per UE, that is, if a terminal device reports this capability, the terminal device can support this capability in all frequency bands). In this way, the signaling overhead of reporting the terminal device capability can be reduced.

[0370] Optionally, the terminal device reports second capability information to the network device, where the second capability information indicates that the terminal device supports configuration-granted PUSCH (CG-PUSCH).

[0371] Optionally, the second capability information is transmitted via RRC signaling or MAC CE.

[0372] Optionally, the description of the first capability information can also be used for the second capability information, and the first capability information and the second capability information can correspond to different or the same options. For example, one capability information is for band, and the other capability information is for per CC per band per band combination. Because uplink and downlink have different requirements on terminal device capabilities, using different options for uplink and downlink capabilities can be more conducive to terminal device implementation.

[0373] Optionally, the first capability information and the second capability information are the same terminal device capability (ie, the third capability information mentioned above), that is, this capability supports determining the uplink transmit spatial filter or spatial related information in CG-PUSCH according to Z1>1 TCI state.

[0462] Optionally, the third information may be the same information as the seventh information. For example, the seventh information only indicates the TCI state corresponding to the first code point (codepoint), does not indicate the TCI state corresponding to other code points other than the first code point, and the first code point corresponds to TCI state X1 and / or TCI state X2, then the terminal device can directly determine the activated TCI state according to TCI state X1 and / or TCI state X2.

[0472] Optionally, if at least one TCI state (denoted as TCI state X) among the one or more TCI states indicated by the third 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 TCI state (denoted as TCI state X) among the one or more TCI states indicated by the third information is different from any of the TCI states currently activated / used (activated, or applied) by the terminal device, starting from the first slot after at least BeamAppTime symbols after the last symbol of the first PUCCH, the TCI state X indicated by the third information takes effect, that is, the terminal device can select the TCI state X according to the TCI state 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 HARQ-ACK information corresponding to the first information DCI.

[0473] Optionally, when the terminal device is about to send the last symbol of the PUCCH with HARQ-ACK information, the HARQ-ACK information corresponds to a DCI carrying a TCI state indication and no DL allocation, or corresponds to a PDSCH scheduled by a DCI carrying a TCI state indication, and if the indicated TCI state is different from the previous indication, the indicated DLorJointTCIState or UL-TCIstate should be applied starting from the first time slot, which is at least the BeamAppTime symbol after the last symbol of the PUCCH. The first time slot and the BeamAppTime symbol are both determined on the carrier with the minimum subcarrier spacing (SCS) in the carrier to which the beam indication is applied.

[0474] Optionally, taking 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. Assuming that the network previously indicated TCI state A1, TCIstate A2 for downlink transmission, the signal indicated by the current DCI contains TCI state X, and TCI state X and TCI state A1 / A2 are different, then the above process can be considered to determine when TCI state X 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 state X, and TCIstate X and TCI state A1 / A2 are different, then the above process can be considered to determine when TCI state X can be used (can be applied).

Optionally, K1 TCI states are used for uplink, K2 TCI states are used for downlink, 0<=K1<=N, 0<=K2<=N, for example, N=K1=K2, or N=K1, K2=0, or other combinations. For example, there may be K1=N UL TCI states, and N JointTCI states may be used for both uplink and downlink, i.e., N=K1=K2.

[0478] Optionally, the terminal device determines the spatial relation (spatialrelation) of the PUSCH corresponding to the configuration authorization, or the uplink transmit spatial filter (UL TX spatial filter) according to the third information.
