[0044] First, the relevant content of this application is introduced.

[0045] I. Cell Free Massive MIMO

[0046] The cell-free massive MIMO system can be regarded as a deconstruction of the traditional massive multiple-input multiple-output (MIMO) system. In the traditional massive MIMO system, antennas are concentratedly distributed at a site (base station), and UEs are distributed around the base station in the form of cells. In the massive MIMO system, each base station deploys a large number of antennas to provide high array gain and spatial resolution. A base station can serve multiple UEs simultaneously on the same time-frequency resources, providing high throughput, high reliability, and high energy efficiency. The cell-free massive MIMO system breaks the concept of cells, and a large number of antennas are scattered over a wide area, and UEs are also scattered over this wide area. These antennas are called transmit-receive points (TRPs) or access points (APs). In theory, each UE can communicate with each AP. With the help of the fronthaul network and the central processing unit (CPU), a large number of geographically dispersed TRPs can jointly serve a relatively small number of UEs, and the CPU uses channel information for joint detection. The Cell Free Massive MIMO network is expected to be applied to indoor and hotspot coverage scenarios of 6G mobile communication systems, such as smart factories, railway stations, shopping malls, stadiums, subways, hospitals, community centers, or university campuses, etc.

[0047] In fact, the cell-free network in the hotspot area can be regarded as a supercell containing multiple TRPs, where multiple TRPs use the same cell ID. There may be different synchronization accuracies and connection relationships between these TRPs, and multiple TRPs can achieve different types of cooperative transmissions.

[0048] II. Multi-TRP (MTRP)

[0049] As the prototype of Cell Free, the 3GPP 5G system introduced MTRP. Except that the CoMP Joint Transmission (CJT) transmission supports up to 4 TRPs for cooperation at most, other transmission schemes support up to 2 TRPs for cooperation at most. Since the backhaul lines between TRPs are divided into two types: ideal (near real-time information interaction) and non-ideal (large delay in information interaction), the implemented multi-TRP transmission schemes are also different.

[0050] In the case of non-ideal backhaul, the achievable transmission scheme is the MTRP (M-DCI based MTRP) scheme for multiple Downlink Control Information (DCI), including:

[0051] 1. The network configures different coresetPoolIndex for different CORESETs, and the DCI associated with different coresetPoolIndex independently schedules their respective PDSCHs, which can be completely / partially / non-overlapping in time-frequency resources;

[0052] 2. The network configures different coresetPoolIndex for different CORESETs, and the DCI associated with different coresetPoolIndex independently schedules their respective PUSCHs, which can be completely / partially / non-overlapping in time-frequency resources. When the PUSCHs are completely / partially overlapping, the UE has the ability to transmit simultaneously on multiple panels.

[0053] In the case of ideal backhaul, in addition to the MTRP scheme scheduled by multiple DCIs that can be achieved above, the transmission schemes that can be achieved by single DCI scheduling (S-DCI based MTRP) also include:

[0054] 1. Two TRPs repeatedly transmit the Physical Downlink Control Channel (PDCCH).

[0055] 2. Two TRPs transmit the PDCCH in the Single Frequency Network (SFN) mode.

[0056] 3. The Physical Downlink Share Channel (PDSCH) scheduled by a single DCI is transmitted by two TRPs in Space Division Multiplexing (SDM), Frequency Division Multiplexing (FDM), time-division multiplexing (TDM) repetition, and SFN modes.

[0057] 4. The UE sends repetitions of the Physical Uplink Control Channel (PUCCH) to two TRPs respectively, or the UE with Simultaneous Transmission with Multiple Panels (STxMP) capability sends the PUCCH simultaneously in SFN mode.

[0058] 5. The UE scheduled by a single DCI or Configured Grant (CG) sends repetitions of the Physical Uplink Share Channel (PUSCH) to two TRPs respectively, or sends the PUSCH simultaneously in SDM or SFN mode.

[0059] III. NR Beam Indication Mechanism

[0060] After beam measurement and beam reporting, the network can perform beam indication on the downlink and uplink channels or reference signals, which is used to establish a beam link between the network and the UE to achieve the transmission of channels or reference signals. For the UE, the beam information is the receive spatial domain filter used by the UE to receive the downlink channel / signal and the transmit spatial domain filter used by the UE to transmit the uplink channel / signal.

[0061] 1. Rel-17 Unified TCI Framework

[0062] Rel-17 introduced the unified TCI framework (UTCI), that is, a common beam indicated by the network using MAC CE and / or DCI can be used for multiple channel transmissions. In NR, the beam information is determined by the Quasi-Colocated (QCL) type D (Type-D) of the Transmission Configuration Indication (TCI) state. The TCI also includes the source reference signal (source RS), and the UE can use the receive / transmit spatial domain filter used to receive or transmit the source reference signal to receive or transmit other channels / signals that have a quasi-colocated relationship with the source reference signal. Specifically, the source RS of the TCI state under the unified TCI framework includes:

[0063] (1) Downlink: Synchronization Signaling Block (SSB), Channel State Information-Reference Signal (CSI-RS) for beam training, Tracking RS (TRS).

[0064] (2) Uplink: SSB, CSI-RS for beam management, Tracking RS, Sounding RS (SRS) for beam management.

[0065] According to whether the uplink and downlink beams are the same, the network can configure the following two modes:

[0066] (1) Joint TCI mode: The network indicates a joint TCI state for the target downlink channel / signal and the target uplink channel / signal, that is, the target downlink channel / signal and the target uplink channel / signal use the same TCI state.

[0067] (2) Separate TCI mode: The network indicates two TCI states - DLTCI state and UL TCI state for the target downlink channel / signal and the target uplink channel / signal respectively, that is, the target uplink channel / signal and the target downlink channel / signal use different TCI states.

[0068] The network configures the TCI state pool through Radio Resource Control (RRC) signaling, and configures and activates the TCI state corresponding to at least one codepoint through the Media Access Control (MAC) Control Element (CE). Each codepoint corresponds to a {joint TCI state}, or the complete set or subset of {DL TCI state, UL TCI state}, that is:

[0069] In the Joint TCI mode, each codepoint corresponds to a joint TCI state;

[0070] In the Separate TCI mode, each codepoint can correspond to the complete set or subset of {DL TCI state, UL TCI state}.

[0071] In the independent TCI mode, when the TCI code point indicated by DCI corresponds to a subset of {DL TCI state, UL TCI state}, only the indicated TCI state is updated, while the other TCI state remains unchanged.

[0072] When the TCI state pool configured by RRC contains only one joint TCI state or a pair of {DL TCI state, UL TCI state}, the TCI state is directly applied to the target channel / signal; when a codepoint is activated by MAC CE, the TCI state corresponding to the codepoint is directly applied to the target channel / signal. When multiple codepoints are activated by MAC CE, the network uses the TCI bitfield in DCI format 1_1 / 1_2 to indicate one of the codepoints, and the TCI state corresponding to the codepoint is applied to the target channel / signal. To ensure the reliability of the updated TCI indication, the network and the UE jointly determine the effective time (Beam Application Time, BAT) of the latest indicated TCI state based on the ACK feedback: when the TCI state indicated by DCI is different from the original TCI state, the latest indicated TCI state starts to be used in the first time slot after Y symbols after the last symbol of the ACK corresponding to the DCI.

[0073] In addition, the unified TCI framework also associates the power control parameters with the TCI state. The path loss reference signal (PathlossRS, PLRS) is configured within the TCI state (joint TCI state or UL TCI state) or associated with the TCI state. Other parameters (P0, alpha, closed loop index) in the power control parameters are configured and associated with the TCI state according to different uplink channels / signals, that is, PUCCH, PUSCH, and SRS have their own power control parameters associated with the TCI state or are included in the configuration information of each channel / signal.

[0074] Considering that different channels / signals or different types of the same channel / signal may use different TCI states, the uplink channels / signals and downlink channels / signals (target channels / signals) using the UTCI state are determined:

[0075] Downlink: UE-specific PDSCH, UE-specific CORESET, aperiodic CSI-RS for channel information / beam management (configurable), non-UE-specific CORESET, and associated PDSCH (configurable), etc.

[0076] Uplink: PUSCH with dynamic grant (DG) / configured grant (CG), PUCCH, periodic / semi-persistent / aperiodic SRS (configurable).

[0077] For channels / signals other than the target channel / signal, the TCI state or spatial relation used is still determined according to the configuration indication method in Rel-15 / 16.

[0078] 2. Unified TCI Framework Extension in Rel-18

[0079] Rel-18 further extends the unified TCI framework for the MTRP scenario, and the basic configuration and indication principle are the same as those defined for single TRP in Rel-17. To implement various transmission schemes in MTRP, two TCI states need to be indicated. Therefore:

[0080] In Joint TCI mode, each codepoint corresponds to the full set or a subset of {joint TCI state1, joint TCI state2}, and it indicates which TCI state each TCI state corresponds to;

[0081] In Separate TCI mode, each codepoint can correspond to the full set or a subset of {DL TCI state1, UL TCI state1, DL TCI state2, UL TCI state2}, and it indicates which TCI state each TCI state corresponds to.

[0082] In both modes, when the TCI codepoint indicated by DCI corresponds to a subset, only the TCI state indicating the subset is updated, while other TCI states remain unchanged.

[0083] When indicating the TCI states of two TRPs, the use of TCI states by each target channel / signal is decoupled from each other, that is, each target channel / signal independently uses one or both of the two indicated joint TCI states, or two DL / UL TCI states:

[0084] The TCI selection field in the downlink DCI indicates that various MTRP transmission schemes of the PDSCH scheduled by a single DCI use two joint TCI states, or either or both of the two DL TCI states; the SRS resource set indicator field in the uplink DCI indicates that various MTRP transmission schemes of the PUSCH scheduled by a single DCI use two joint TCI states, or either or both of the two UL TCI states;

[0085] The RRC parameter configures each CORESET, aperiodic CSI-RS resource / CSI-RS resource set to use two joint TCI states, or either or both of the two DL TCI states; the RRC parameter configures each PUCCH resource / PUCCH resource group, SRS resource to use two joint TCI states, or either or both of the two UL TCI states.

[0086] 3. Unified TCI update for multiple CCs / BWPs

[0087] In a multi-component carrier (CC) / bandwidth part (BWP) scenario, up to four CC lists can be configured, and each CC list updates the TCI state jointly. A TCI state pool can be configured on one of the reference CCs in a CC list. When any CC in the CC list indicates an update of the TCI state, all CCs in the CC list use the updated TCI state simultaneously. Multiple CCs in the CC list are all STRP, S-DCI based MTRP, or M-DCI based MTRP.

[0088] The following combines the accompanying drawings and details the transmission configuration method provided in the embodiments of the present application through some embodiments and their application scenarios.

[0089] The embodiments of the present application provide a transmission configuration method. Referring to Figure 2 shows a flowchart of a transmission configuration method provided in the embodiments of the present application. This method is applied to a network-side device, such as Figure 2 shown, and the method may specifically include:

[0090] Step 101, the network-side device indicates first information to the terminal device.

[0091] Wherein, the first information includes at least one transmission configuration indication; the transmission configuration indication satisfies at least one of the following:

[0092] Each transmission configuration indicates at least one type of channel or signal;

[0093] Each transmission configuration indicates at least one type or use of at least one type of channel or signal.

[0094] It should be noted that the transmission configuration method provided in the embodiments of this application can be used in a single-TRP scenario or a multi-TRP scenario. The network-side device can indicate one or more TCIs to the terminal device through first information, and each TCI included in the first information can be used for different channels or signals, or for different types or uses of the same type of channel or signal.

[0095] Among them, the channel or signal corresponding to the TCI indicated by the first information can be a downlink channel / signal. For example, it can include but is not limited to: downlink synchronization signal block (NR calls it SSB), downlink tracking reference signal (NR calls it TRS), downlink channel state information reference signal (NR calls it CSI-RS), downlink demodulation reference signal (NR calls it DMRS), downlink phase tracking reference signal (NR calls it PTRS), downlink control channel - physical downlink control channel (NR calls it PDCCH), downlink data channel - physical downlink shared channel (NR calls it PDSCH), etc. Or, the channel or signal corresponding to the TCI indicated by the first information can also be an uplink channel / signal. For example, it can include but is not limited to: uplink sounding reference signal (NR calls it SRS), uplink demodulation reference signal (NR calls it DMRS), uplink phase tracking reference signal (NR calls it PTRS), uplink control channel - physical uplink control channel (NR calls it PUCCH), uplink data channel - physical uplink shared channel (NR calls it PUSCH), etc.

[0096] For different types or uses of the same type of channel or signal, different beam / QCL information corresponding to different TCIs can be used. The type / use of the channel or signal corresponding to the TCI indicated by the first information can be determined according to factors such as the time-domain characteristics of the channel or signal (such as period, semi-persistent, aperiodic, etc.), information attributes (such as common information, dedicated information, broadcast / multicast information, unicast information, etc.), uses (such as channel measurement, beam training, time-frequency synchronization, etc.).

[0097] For example, the PDCCH for common control information (common) needs to be received by multiple UEs and usually uses a wide beam; while the PDCCH for sending UE-specific control information only needs to be received by this UE and is sent using a narrow beam targeting this UE.

[0098] The data channel PDSCH for broadcast / multicast needs to be received by multiple UEs, while the data channel PDSCH for unicast only needs to be received by the UE itself. Therefore, different beams will be used.

[0099] For another example, the beams used for CSI-RS for beam scanning and CSI-RS for measuring the downlink channel information under the current beam are also different. The beams used for SRS for beam training and SRS for measuring the uplink channel information under the current beam (SRS for codebook or non-codebook, antenna switching) are also different.

[0100] It can be understood that the network-side device can indicate the first information to the terminal device through at least one of RRC signaling, MAC signaling, and DCI.

[0101] After receiving the first information, the terminal device can, according to the TCI included in the first information, and the channel or signal corresponding to each TCI, or the type or use of the channel or channel corresponding to each TCI, use the corresponding TCI for the transmission of a certain channel or signal, or a certain channel or signal of a certain type or use.

[0102] As an example, the first information in the embodiments of this application may include at least one of {TCI1,…,TCIM,TCIlist1,…,TCI listN}, and indicates the channel / signal applicable to each TCI or TCI list, or the type / use of the channel / signal, as shown in Table 1:

[0103] Table 1

[0104]

[0105] Among them, the TCI shown in Table 1 is a joint TCI mode, and the uplink and downlink TCIs are the same.

[0106] Then, after receiving the first information, the terminal device can perform the following transmission operations:

[0107] Receive control channel type 1 or broadcast data channel using TCI1;

[0108] Receive control channel type 2, unicast downlink data channel, CSI-RS type 1, and send uplink control channel, uplink data channel or SRS type 1 using TCI2;

[0109] Receive 4 CSI-RS resources of CSI-RS type 2 using TCI3, TCI4, TCI5, and TCI6 respectively;

[0110] Use TCI4 and TCI7 to send two SRS resources of SRS type 2 respectively.

[0111] Optionally, the method further includes:

[0112] The network side device sends target indication information to the terminal device.

[0113] Wherein, the target indication information includes at least one of the following:

[0114] A first indication, which is used to indicate the channel or signal corresponding to the at least one transmission configuration indication in the first information;

[0115] A second indication, which is used to indicate the type or use of the channel or signal corresponding to the at least one transmission configuration indication in the first information.

[0116] In the embodiment of the present application, after the network side device indicates the first information to the terminal device, it can further indicate to the terminal device the channel or signal applicable to TCI in the first information through the target indication information, and / or indicate the type or use of the channel / signal applicable to TCI in the first information.

[0117] After receiving the target indication information, when the terminal device sends or receives a certain channel or signal, it can select the corresponding TCI for sending or receiving based on the correspondence between TCI and the channel or signal in the first information indicated by the target indication information. Or, when the terminal device sends or receives a channel or signal of a certain type or use, it can select the corresponding TCI for sending or receiving based on the correspondence between TCI and the type or use of the channel or signal in the first information indicated by the target indication information.

[0118] Optionally, the network side device sending the target indication information to the terminal device includes:

[0119] The network side device sends a first signaling to the terminal device, and the target indication information is carried in the first signaling.

[0120] Wherein, the first signaling includes at least one of the following:

[0121] A signaling for indicating the first information;

[0122] A signaling for indicating at least one transmission configuration indication in the first information.

[0123] In the embodiments of the present application, the target indication information may be carried in the signaling for indicating the first information, or may be carried in the signaling for indicating one or more TCIs in the first information. For example, the target indication information may be carried in the RRC signaling for configuring the first information or TCI, or carried in the MAC signaling for activating the first information or TCI, or carried in the DCI for indicating the first information or TCI, and so on.

[0124] Of course, the network-side device may also use other signaling to separately send the target indication information to the terminal device.

[0125] Optionally, the channel or signal and the transmission configuration indication satisfy at least one of the following:

[0126] The channel or signal included in the first information uses the transmission configuration indication indicated by the first information;

[0127] The transmission configuration indications corresponding to other channels or signals except the channels or signals included in the first information remain unchanged;

[0128] The type or use of the channel or signal included in the first information uses the transmission configuration indication indicated by the first information;

[0129] The transmission configuration indications corresponding to other types or uses except the type or use of the channel or signal included in the first information remain unchanged.

[0130] In the embodiments of the present application, the network-side device may update the TCI corresponding to the channel or signal according to the first information, or update the TCI corresponding to the type or use of the channel or signal. Among them, the channel or signal already indicated in the first information, or the type or use of the channel or signal already indicated in the first information, uses the TCI indicated by the first information; other channels or signals, or other types or uses of the channel or signal, continue to use the original TCI.

[0131] For example, assume that after the network-side device indicates the first information shown in Table 1 through DCI, it indicates the first information shown in Table 2 again:

[0132] Table 2

[0133]

[0134] Then, the terminal device performs the following transmission operations:

[0135] Still receive the control channel type 1 or the broadcast data channel using TCI1;

[0136] Use TCI10 to receive control channel type 2, unicast downlink data channel, CSI-RS type 1, and send uplink control channel, uplink data channel or SRS type 1;

[0137] Still use TCI3, TCI4, TCI5, and TCI6 to receive 4 CSI-RS resources of CSI-RS type 2 respectively;

[0138] Still use TCI4 and TCI7 to send 2 SRS resources of SRS type 2 respectively.

[0139] As another example, assume that the first information indicated by the network side device includes at least one of {TCI1,..., TCIM, TCIlist1,..., TCI listN}, and indicates the channel / signal to which each TCI or TCI list applies, or the type / usage of the channel / signal, as shown in Table 3 (independent TCI mode, uplink and downlink TCIs are different):

[0140] Table 3

[0141]

[0142]

[0143] Then, after receiving the first information, the terminal device performs the following transmission operations:

[0144] Use TCI1 to receive control channel type 1 or broadcast data channel;

[0145] Use TCI2 to receive control channel type 2, unicast downlink data channel, CSI-RS type 1;

[0146] Use TCI4 to send uplink control channel, uplink data channel or SRS type 1;

[0147] Use TCI3, TCI4, TCI5, and TCI6 to receive 4 CSI-RS resources of CSI-RS type 2 respectively;

[0148] Use TCI4 and TCI7 to send 2 SRS resources of SRS type 2 respectively.

[0149] Assume that after the network side device indicates the first information shown in Table 3 through DCI, it indicates the first information shown in Table 4 again:

[0150] Table 4

[0151]

[0152] Then, the terminal device performs the following transmission operations:

[0153] Still use TCI1 to receive control channel type 1 or broadcast data channel;

[0154] Still use TCI2 to receive control channel type 2, unicast downlink data channel, CSI-RS type 1;

[0155] Use TCI11 to transmit uplink control channel, uplink data channel or SRS type 1;

[0156] Still use TCI3, TCI4, TCI5, TCI6 to receive 4 CSI-RS resources of CSI-RS type 2 respectively;

[0157] Still use TCI4 and TCI7 to transmit 2 SRS resources of SRS type 2 respectively.

[0158] Optionally, the network side device indicates first information to the terminal device, including at least one of the following:

[0159] The network side device indicates at least one first information group to the terminal device; the first information group includes at least one first information;

[0160] The network side device indicates at least one first information included in at least one of the first information groups to the terminal device.

[0161] In a multi-TRP scenario, the network side device may also indicate a first information group to the terminal device, and each first information group includes at least one first information.

[0162] The indication information of the first information group and the indication information of the first information included in the first information group may be sent simultaneously or in different signaling.

[0163] Optionally, the network side device indicates at least one first information group to the terminal device, including:

[0164] The network side device sends a second signaling to the terminal device; the second signaling is used to indicate at least one of the first information groups.

[0165] In a possible application scenario, the network side device may pre-configure the correspondence between the first information group and the first information, and then through the second signaling, indicate the first information group to the terminal device. After receiving the second signaling, the terminal device may determine the first information included in the first information group indicated by the second signaling according to the correspondence between the first information group and the first information.

[0166] Optionally, at least one of the first information groups indicated by the second signaling becomes effective, or all the first information included in the first information group indicated by the second signaling becomes effective.

[0167] If the network - side device indicates one or more first information groups through a second signaling, the terminal device may consider that each of the first information groups indicated by the second signaling becomes effective after reaching the effective time, or all the first information included in the first information group indicated in the second signaling becomes effective after reaching the effective time.

[0168] Optionally, the network - side device indicates at least one first information included in at least one of the first information groups to the terminal device, including:

[0169] The network - side device sends a third signaling to the terminal device; the third signaling is used to indicate the first information.

[0170] When one of the first information groups indicated by the second signaling becomes effective, the first information indicated by the third signaling is the first information in one of the first information groups indicated by the second signaling;

[0171] When at least two of the first information groups indicated by the second signaling become effective, the first information indicated by the third signaling is the first information in at least two of the first information groups indicated by the second signaling, and the first information included in each of the at least two first information groups is determined according to the correspondence between the first information groups indicated by the second signaling and the first information indicated by the third signaling.

[0172] For example, when the second signaling indicates one first information group, the UE uses the first information within the first information group indicated by the third signaling to receive or transmit signals. In this way, when the first information group changes, TCI switching of the TRP group can be achieved; when multiple first information indicated by the third signaling belong to the same first information group, the UE uses the multiple first information within the first information group to receive or transmit signals, so as to achieve multiple TCI co - reception or co - transmission within the TRP group; when multiple first information indicated by the third signaling belong to at least two first information groups indicated by the second signaling, the UE uses the multiple first information within the above - mentioned at least two first information groups to receive or transmit signals, so as to achieve TCI co - reception or co - transmission between TRP groups.

[0173] Optionally, the method further includes:

[0174] The network - side device sends a third indication to the terminal device; the third indication is used to indicate the correspondence between the first information groups indicated by the second signaling and the first information indicated by the third signaling.

[0175] When the second signaling indicates at least two first information groups, the network-side device may indicate to the terminal device, via a third indication, the correspondence between the first information groups indicated by the second signaling and the first information indicated by the third signaling, so that the terminal device can determine the first information included in each of the first information groups indicated by the second signaling.

[0176] Optionally, the network-side device indicating at least one first information included in at least one of the first information groups to the terminal device includes:

[0177] The network-side device sends a fourth signaling to the terminal device; the fourth signaling is used to indicate the first information group and at least one first information included in the first information group.

[0178] Optionally, the first signaling further includes a fourth indication, and the fourth indication is used to indicate the first information group to which the first information belongs.

[0179] In an embodiment of the present application, the network-side device may also, via the fourth signaling or the first signaling, simultaneously indicate to the terminal device the first information group and the first information included in the first information group.

[0180] It should be noted that the first signaling, the second signaling, the third signaling, and the fourth signaling in the embodiments of the present application may all be RRC signaling, MAC signaling, or DCI.

[0181] Optionally, the method further includes:

[0182] The network-side device configures at least one first configuration pool, and the first configuration pool includes at least one of the first information.

[0183] In the first configuration pool, the first information and the transmission configuration indication satisfy at least one of the following:

[0184] The first information and the transmission configuration indication use the same set of index numbers;

[0185] The first information and the transmission configuration indication use different index numbers.

[0186] In an embodiment of the present application, the network-side device may also configure a first configuration pool. The first configuration pool is a TCI state pool, and may include the first information in the embodiments of the present application, or may include other TCIs other than the TCIs included in the first information.

[0187] In the first configuration pool, the first information may use the same set of index numbers as the TCI it includes, or may use different index numbers (the first information and the TCI are numbered separately).

[0188] Optionally, the network side device configures at least one first configuration pool, including:

[0189] The network side device configures the at least one first configuration pool in the public configuration information.

[0190] In the embodiment of the present application, the first configuration pool can be located in the public configuration information outside the serving cell configuration information, so that all cells can access the first configuration pool.

[0191] Optionally, the method further includes:

[0192] The network side device sends a fifth indication to the terminal device; the fifth indication is used to indicate that each of the transmission configuration indication or the first information or the first information group corresponds to at least one member carrier or bandwidth part.

[0193] In the embodiment of the present application, the network side device can also configure the corresponding member carrier CC or bandwidth part BWP for each TCI, or each first information, or each first information group respectively.

[0194] For example, the network side device configures a first configuration pool, and each TCI state in it configures one or more CCs or BWPs using this TCI state. After the UE receives the TCI state that activates or indicates a certain CC or BWP, it interprets the corresponding TCI state serial number of this CC or BWP according to the number of TCI states associated with the CC or BWP used for each TCI state configuration in the TCI state pool.

[0195] As an example, the configuration of a first configuration pool is as follows:

[0196] TCI state1: CC1, CC2

[0197] TCI state2: CC1

[0198] TCI state3: CC1, CC3

[0199] TCI state4: CC2

[0200] TCI state5: CC2, CC3

[0201] Then, the TCI states corresponding to each CC can be: (the TCI state serial numbers in the TCI state pool are in parentheses)

[0202] The TCI states of CC1 are: TCI state1 (TCI state1), TCI state2 (TCI state2), TCI state3 (TCI state3).

[0203] The TCI states of CC2 are: TCI state1 (TCI state1), TCI state2 (TCI state4), TCI state3 (TCI state5).

[0204] The TCI states of CC3 are: TCI state1 (TCI state3), TCI state2 (TCI state5).

[0205] When a TCI state is indicated on a certain CC, the TCI state is used together with one or more CCs corresponding to the TCI state.

[0206] In summary, the embodiments of the present application provide a transmission configuration method. The network-side device can, through the first information, indicate the TCI corresponding to different channels or signals to the terminal device, and / or indicate the TCI corresponding to different types or uses of the same channel or signal to the terminal device, so that the terminal device can select the corresponding TCI for transmission according to the channel or signal, or the type / use of the channel / signal. The embodiments of the present application can perform unified TCI indication on multiple channels or signals, and / or multiple types or uses of the same channel or signal, through the first information, and there is no need to distinguish whether the channel or signal uses UTCI. Compared with the related art in which different indication methods are adopted for channels / signals using UTCI and those not using UTCI, the embodiments of the present application improve the flexibility and configuration efficiency of TCI configuration.

[0207] The embodiments of the present application also provide another transmission configuration method. Refer to Figure 3 , which shows a flowchart of another transmission configuration method provided by the embodiments of the present application. This method is applied to a terminal device. As Figure 3 shown, this method may specifically include:

[0208] Step 201, the terminal device obtains the first information indicated by the network-side device;

[0209] Step 202, the terminal device performs transmission based on the first information.

[0210] Among them, the first information includes at least one transmission configuration indication; the transmission configuration indication satisfies at least one of the following:

[0211] Each transmission configuration indication corresponds to at least one channel or signal;

[0212] Each transmission configuration indicates at least one type or use corresponding to at least one channel or signal.

[0213] The transmission configuration method provided by the embodiments of this application can be used in a single-TRP scenario or a multi-TRP scenario. The network-side device can indicate one or more TCIs to the terminal device through first information, and each TCI included in the first information can be used for different channels or signals, or for different types or uses of the same channel or signal.

[0214] Among them, the channel or signal corresponding to the TCI indicated by the first information can be a downlink channel / signal. For example, it can include but is not limited to: downlink synchronization signal block (referred to as SSB in NR), downlink tracking reference signal (referred to as TRS in NR), downlink channel state information reference signal (referred to as CSI-RS in NR), downlink demodulation reference signal (referred to as DMRS in NR), downlink phase tracking reference signal (referred to as PTRS in NR), downlink control channel - physical downlink control channel (referred to as PDCCH in NR), downlink data channel - physical downlink shared channel (referred to as PDSCH in NR), etc. Alternatively, the channel or signal corresponding to the TCI indicated by the first information can also be an uplink channel / signal. For example, it can include but is not limited to: uplink sounding reference signal (referred to as SRS in NR), uplink demodulation reference signal (referred to as DMRS in NR), uplink phase tracking reference signal (referred to as PTRS in NR), uplink control channel - physical uplink control channel (referred to as PUCCH in NR), uplink data channel - physical uplink shared channel (referred to as PUSCH in NR), etc.

[0215] For different types or uses of the same channel or signal, different beam / QCL information corresponding to different TCIs can be used. The type / use of the channel or signal corresponding to the TCI indicated by the first information can be determined according to factors such as the time-domain characteristics of the channel or signal (such as periodic, semi-persistent, aperiodic, etc.), information attributes (such as common information, dedicated information, broadcast / multicast information, unicast information, etc.), uses (such as channel measurement, beam training, time-frequency synchronization, etc.).

[0216] For example, the PDCCH for common control information (common) needs to be received by multiple UEs and usually uses a wide beam; while the PDCCH for sending UE-specific control information only needs to be received by this UE and is sent using a narrow beam targeted at this UE.

[0217] The data channel PDSCH for broadcast / multicast needs to be received by multiple UEs, while the data channel PDSCH for unicast only needs to be received by this UE, so the beams used will also be different.

[0218] For another example, the CSI-RS for beam scanning and the beam used by the CSI-RS for measuring the downlink channel information under the current beam are also different. The SRS for beam training and the SRS for measuring the uplink channel information under the current beam (the SRS for codebook or non-codebook, antenna switching) are also different.

[0219] After receiving the first information, the terminal device may, according to the TCI included in the first information, and the channel or signal corresponding to each TCI, or the type or use of the channel or channel corresponding to each TCI, use the corresponding TCI for a certain channel or signal, or a certain channel or signal of a certain type or use for transmission.

[0220] Optionally, the method further includes:

[0221] The terminal device receives the target indication information sent by the network device.

[0222] Wherein, the target indication information includes at least one of the following:

[0223] A first indication, the first indication is used to indicate the channel or signal corresponding to the at least one transmission configuration indication in the first information;

[0224] A second indication, the second indication is used to indicate the type or use of the channel or signal corresponding to the at least one transmission configuration indication in the first information.

[0225] In the embodiments of the present application, after the network device indicates the first information to the terminal device, it may further indicate to the terminal device, through the target indication information, the channel or signal to which the TCI included in the first information is applicable, and / or indicate the type or use of the channel / signal to which the TCI included in the first information is applicable.

[0226] After receiving the target indication information, when the terminal device sends or receives a certain channel or signal, it may select the corresponding TCI for sending or receiving based on the correspondence between the TCI in the first information indicated by the target indication information and the channel or signal. Alternatively, when the terminal device sends or receives a channel or signal of a certain type or use, it may select the corresponding TCI for sending or receiving based on the correspondence between the TCI in the first information indicated by the target indication information and the type or use of the channel or channel.

[0227] Optionally, the terminal device receiving the target indication information sent by the network device includes:

[0228] The terminal device receives a first signaling sent by the network device, and the target indication information is carried in the first signaling.

[0229] Among them, the first signaling includes at least one of the following:

[0230] Signaling for indicating the first information;

[0231] Signaling for indicating at least one transmission configuration indication in the first information.

[0232] In the embodiments of the present application, the target indication information may be carried in the signaling for indicating the first information, or may be carried in the signaling for indicating one or more TCIs in the first information. For example, the target indication information may be carried in the RRC signaling for configuring the first information or TCI, or carried in the MAC signaling for activating the first information or TCI, or carried in the DCI for indicating the first information or TCI, and so on.

[0233] Of course, the network-side device may also use other signaling to separately send the target indication information to the terminal device.

[0234] Optionally, the channel or signal and the transmission configuration indication satisfy at least one of the following:

[0235] The channel or signal included in the first information uses the transmission configuration indication indicated by the first information;

[0236] The transmission configuration indications corresponding to other channels or signals except the channels or signals included in the first information remain unchanged;

[0237] The type or use of the channel or signal included in the first information uses the transmission configuration indication indicated by the first information;

[0238] The transmission configuration indications corresponding to other types or uses except the type or use of the channel or signal included in the first information remain unchanged.

[0239] In the embodiments of the present application, the terminal device may update the TCI corresponding to the channel or signal according to the first information, or update the TCI corresponding to the type or use of the channel or signal. Among them, the channel or signal already indicated in the first information, or the type or use of the channel or signal already indicated in the first information, uses the TCI indicated by the first information; other channels or signals, or other types or uses of the channel or signal, continue to use the original TCI.

[0240] Optionally, the terminal device obtains the first information indicated by the network-side device, including at least one of the following:

[0241] The terminal device determines at least one first information group indicated by the network-side device; the first information group includes at least one first information;

[0242] The terminal device determines at least one piece of first information included in at least one of the first information groups indicated by the network - side device.

[0243] In a multi - TRP scenario, the network - side device may further indicate a first information group to the terminal device, and each first information group includes at least one piece of first information.

[0244] The indication information of the first information group and the indication information of the first information included in the first information group may be sent simultaneously or in different signaling.

[0245] Optionally, the terminal device determines at least one of the first information groups indicated by the network - side device, including:

[0246] The terminal device receives a second signaling sent by the network - side device; the second signaling is used to indicate at least one of the first information groups.

[0247] In a possible application scenario, the network - side device may pre - configure the correspondence between the first information group and the first information, and then, through the second signaling, indicate the first information group to the terminal device. After receiving the second signaling, the terminal device may determine the first information included in the first information group indicated by the second signaling according to the correspondence between the first information group and the first information.

[0248] Optionally, at least one of the first information groups indicated by the second signaling becomes effective, or all of the first information included in the first information group indicated by the second signaling becomes effective.

[0249] If the network - side device indicates one or more first information groups through the second signaling, the terminal device may consider that each of the first information groups indicated by the second signaling becomes effective after reaching the effective time, or all of the first information included in the first information group indicated in the second signaling becomes effective after reaching the effective time.

[0250] Optionally, the terminal device determines at least one piece of first information included in at least one of the first information groups indicated by the network - side device, including:

[0251] The terminal device receives a third signaling sent by the network - side device; the third signaling is used to indicate the first information.

[0252] In the case where one of the first information groups indicated by the second signaling becomes effective, the first information indicated by the third signaling is the first information in one of the first information groups indicated by the second signaling;

[0253] When at least two of the first information groups indicated by the second signaling become effective, the first information indicated by the third signaling is the first information in at least two of the first information groups indicated by the second signaling, and the first information included in each of the at least two first information groups is determined according to the correspondence between the first information group indicated by the second signaling and the first information indicated by the third signaling.

[0254] For example, when the second signaling indicates one first information group, the UE uses the first information within the first information group indicated by the third signaling to receive or transmit signals. In this way, a change in the first information group can achieve TCI switching of the TRP group; when multiple first information indicated by the third signaling belong to the same first information group, the UE uses the multiple first information within the first information group to receive or transmit signals, so as to achieve co-reception or co-transmission of multiple TCIs within the TRP group; when multiple first information indicated by the third signaling belong to at least two first information groups indicated by the second signaling, the UE uses the multiple first information within the at least two first information groups to receive or transmit signals, so as to achieve co-reception or co-transmission of TCIs between TRP groups.

[0255] Optionally, the method further includes:

[0256] The terminal device receives a third indication sent by the network side device; the third indication is used to indicate the correspondence between the first information group indicated by the second signaling and the first information indicated by the third signaling.

[0257] When the second signaling indicates at least two first information groups, the network side device can indicate to the terminal device the correspondence between the first information group indicated by the second signaling and the first information indicated by the third signaling through the third indication. Based on the third indication and the first information indicated by the third signaling, the terminal device can determine the first information included in each first information group indicated by the second signaling.

[0258] Optionally, when the terminal device determines at least one first information included in at least one first information group indicated by the network side device, it includes:

[0259] The terminal device receives a fourth signaling sent by the network side device; the fourth signaling is used to indicate the first information group and at least one first information included in the first information group.

[0260] Optionally, the first signaling further includes a fourth indication, and the fourth indication is used to indicate the first information group to which the first information belongs.

[0261] In an embodiment of the present application, the network - side device may also use a fourth signaling or a first signaling to simultaneously indicate a first information group and first information included in the first information group to the terminal device.

[0262] Optionally, the method further includes:

[0263] The terminal device receives a fifth indication sent by the network - side device; the fifth indication is used to indicate that each of the transmission configuration indication or the first information or the first information group corresponds to at least one member carrier or bandwidth part.

[0264] In an embodiment of the present application, the network - side device may also configure a corresponding member carrier CC or bandwidth part BWP for each TCI, or each first information, or each first information group respectively. After receiving the fifth indication, the terminal device can determine the TCI corresponding to each CC or BWP.

[0265] In summary, for a transmission configuration method provided by an embodiment of the present application, the terminal device can determine the TCIs corresponding to different channels or signals, and / or the TCIs corresponding to different types or uses of the same channel or signal according to the first information indicated by the network - side device, and thus select the corresponding TCI for transmission according to the channel or signal, or the type / use of the channel / signal. The embodiment of the present application can adopt a unified TCI indication method for multiple channels or signals, and multiple types or uses of the same channel or signal, and there is no need to distinguish whether the channel or signal uses UTCI. Compared with the related art that adopts different indication methods for channels / signals using UTCI and those not using UTCI, the embodiment of the present application improves the flexibility and configuration efficiency of TCI configuration.
