[0047] First, the content related to this application is introduced.

[0048] 1. Cell-Free Massive MIMO

[0049] Cell-free massive MIMO systems can be considered a deconstruction of traditional massive Multiple-Input Multiple-Output (MIMO) systems. In traditional massive MIMO systems, antennas are concentrated at a single site (base station), and UEs are distributed around the base station in cells. In massive MIMO systems, each base station deploys a large number of antennas, providing higher array gain and spatial resolution. A single base station can simultaneously serve multiple UEs using the same time-frequency resources, delivering high throughput, high reliability, and high energy efficiency. Cell-free massive MIMO systems eliminate the concept of cells. Instead, a large number of antennas are distributed over a wide area, and UEs are similarly dispersed across this wide area. These antennas are called Transmit-Receive Points (TRPs) or Access Points (APs). In theory, each UE can communicate with every AP. Leveraging the fronthaul network and the central processing unit (CPU), a large number of geographically dispersed TRPs can collectively serve a relatively small number of UEs. The CPU utilizes channel information for joint detection. Cell-Free Massive MIMO networks are expected to be applied to indoor and hotspot coverage scenarios of 6G mobile communication systems, such as smart factories, train stations, shopping malls, stadiums, subways, hospitals, community centers, or university campuses.

[0050] In fact, the Cell-free network in the hotspot area can be regarded as a super cell containing multiple TRPs, where multiple TRPs use the same cell ID. These TRPs may have different synchronization accuracy and connection relationships, and multiple TRPs can implement collaborative transmission in different ways.

[0051] 2. Multi-TRP (MTRP)

[0052] As a precursor to Cell Free, 3GPP 5G systems introduced Multi-Point Transmission (MTRP). With the exception of CoMP Joint Transmission (CJT), which supports up to four coordinated TRPs, other transmission schemes support up to two coordinated TRPs. Because backhaul between TRPs can be ideal (near-real-time information exchange) or non-ideal (with significant information delays), the implementation of multiple TRP transmission schemes varies.

[0053] In non-ideal backhaul scenarios, the achievable transmission solution is the M-DCI based MTRP solution for multiple downlink control information (DCI), including:

[0054] 1. The network configures different coresetPoolIndex for different CORESETs. DCIs associated with different coresetPoolIndex independently schedule their respective PDSCHs, which can be completely / partially / non-overlapping in time-frequency resources.

[0055] 2. The network configures different coresetPoolIndex for different CORESETs. 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 completely / partially overlap, the UE has the capability of multi-panel simultaneous transmission.

[0056] In an ideal backhaul scenario, in addition to the aforementioned MTRP scheme for multiple DCI scheduling, transmission schemes that can implement single DCI scheduling (S-DCI based MTRP) include:

[0057] 1. Two TRPs repeatedly send the Physical Downlink Control Channel (PDCCH).

[0058] 2. Two TRPs send PDCCH in a single frequency network (SFN) manner.

[0059] 3. A single DCI-scheduled physical downlink shared channel (PDSCH) is sent by two TRPs using space division multiplexing (SDM), frequency division multiplexing (FDM), and time division multiplexing (TDM) repetition and SFN.

[0060] 4. The UE sends repetitions of the Physical Uplink Control Channel (PUCCH) to two TRPs respectively, or a UE with Simultaneous Transmission with Multiple Panels (STxMP) capability sends PUCCH simultaneously in SFN mode.

[0061] 5. A UE with a single DCI schedule or configured grant (CG) sends repeated physical uplink shared channels (PUSCH) to two TRPs respectively, or sends PUSCH simultaneously in SDM or SFN mode.

[0062] NR Beam Indication Mechanism

[0063] After beam measurement and reporting, the network can provide beam indications for downlink and uplink channels or reference signals, which are used to establish a beam link between the network and the UE and enable channel or reference signal transmission. For the UE, beam information refers to the receive spatial domain filter used by the UE to receive downlink channels / signals and the transmit spatial domain filter used by the UE to transmit uplink channels / signals.

[0064] 1. Rel-17 Unified TCI Framework

[0065] Rel-17 introduced a 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 of the Transmission Configuration Indication (TCI) state. TCI also includes a source reference signal (source RS), so that the UE can use the receive / transmit spatial domain filter used to receive or send the source reference signal to receive or send other channels / signals that have a quasi-co-location relationship with the source reference signal. Specifically, the source RS of the TCI state under the unified TCI framework includes:

[0066] (1) Downlink: Synchronization Signaling Block (SSB), Channel State Information-Reference Signal (CSI-RS) for beam training, and Tracking RS (TRS).

[0067] (2) Uplink: SSB, CSI-RS for beam management, tracking CSI-RS, and sounding reference signal (SRS) for beam management.

[0068] Depending on whether the uplink and downlink beams are the same, the network can be configured in the following two modes:

[0069] (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.

[0070] (2) Separate TCI mode: The network indicates two TCI states: the DL TCI state and the 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.

[0071] 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 full set or subset of {DL TCI state, UL TCI state}, namely:

[0072] In Joint TCI mode, each codepoint corresponds to a joint TCI state;

[0073] In Separate TCI mode, each codepoint can correspond to the full set or a subset of {DL TCI state, UL TCI state}.

[0074] In independent TCI mode, when the TCI code point indicated by the 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.

[0075] 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 the MAC CE activates a codepoint, the TCI state corresponding to the codepoint is directly applied to the target channel / signal. When the MAC CE activates multiple codepoints, the network uses the TCI field in the 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 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 the DCI is different from the original TCI state, the latest indicated TCI state is used starting from the first time slot after Y symbols of the last ACK symbol corresponding to the DCI.

[0076] In addition, the unified TCI framework links power control parameters to TCI states. Pathloss reference signals (PLRS) are configured within or associated with TCI states (joint TCI state or UL TCI state). Other power control parameters (P0, alpha, closed loop index) are configured and associated with TCI states based on the uplink channel / signal. This means that PUCCH, PUSCH, and SRS each have their own power control parameters associated with the TCI state or included in the configuration information for each channel / signal.

[0077] Considering that different channels / signals or different types of the same channel / signal may use different TCI states, the uplink channel / signal and downlink channel / signal (target channel / signal) using the UTCI state are determined:

[0078] 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.

[0079] Uplink: PUSCH, PUCCH with dynamic grant (DG) / configured grant (CG), periodic / semi-persistent / aperiodic SRS (configurable).

[0080] 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 of Rel-15 / 16.

[0081] 2. Unified TCI framework extension of Rel-18

[0082] Rel-18 further expands the unified TCI framework for MTRP scenarios. The basic configuration and indication principles are consistent with the single TRP defined in Rel-17. To implement various MTRP transmission schemes, two TCI states need to be indicated. Therefore:

[0083] In Joint TCI mode, each codepoint corresponds to the full set or subset of {joint TCI state1, joint TCI state2}, and indicates which TCI state each codepoint corresponds to;

[0084] 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 indicate which TCI state each TCI state corresponds to.

[0085] In both modes, when the TCI codepoint indicated by the DCI corresponds to a subset, only the TCI state of the indicated subset is updated, while other TCI states remain unchanged.

[0086] In the case of a TCI state indicating two TRPs, the TCI states used by each target channel / signal are decoupled from each other, that is, each target channel / signal independently uses the two indicated joint TCI states, or either or both of the two DL / UL TCI states:

[0087] The TCI selection field in the downlink DCI indicates that the various MTRP transmission schemes for 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 the various MTRP transmission schemes for the PUSCH scheduled by a single DCI use two joint TCI states, or either or both of the two UL TCI states;

[0088] The RRC parameters configure 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 parameters configure each PUCCH resource / PUCCH resource group, SRS resource to use two joint TCI states, or either or both of the two UL TCI states.

[0089] 3. Unified TCI update for multiple CC / BWP

[0090] In a multi-component carrier (CC) / bandwidth part (BWP) scenario, up to four CC lists can be configured, and each CC list jointly updates the TCI state. A TCI state pool can be configured on a reference CC in a CC list. When any CC in the CC list indicates a TCI state update, all CCs in the CC list use the updated TCI state simultaneously. Multiple CCs in the CC list can be STRP, S-DCI-based MTRP, or M-DCI-based MTRP.

[0091] The transmission configuration method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0092] The present application provides a transmission configuration method. Referring to FIG2 , a flow chart of a transmission configuration method provided by the present application is shown. The method is applied to a network-side device, as shown in FIG2 , and the method may specifically include:

[0093] Step 101: A network-side device indicates first information to a terminal device.

[0094] The first information includes at least one transmission configuration indication; the transmission configuration indication satisfies at least one of the following:

[0095] Each transmission configuration indication corresponds to at least one channel or signal;

[0096] Each transmission configuration indicates at least one type or usage of at least one channel or signal.

[0097] It should be noted that the transmission configuration method provided in the embodiment of the present 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 the first information, and each TCI contained in the first information can be used for different channels or signals, or for different types or uses of the same channel or signal.

[0098] The channel or signal corresponding to the TCI indicated by the first information may be a downlink channel / signal, for example, including but not limited to: a downlink synchronization signal block (called SSB by NR), a downlink tracking reference signal (called TRS by NR), a downlink channel state information reference signal (called CSI-RS by NR), a downlink demodulation reference signal (called DMRS by NR), a downlink phase tracking reference signal (called PTRS by NR), a downlink control channel - a physical downlink control channel (called PDCCH by NR), a downlink data channel - a physical downlink shared channel (called PDSCH by NR), etc. Alternatively, the channel or signal corresponding to the TCI indicated by the first information may also be an uplink channel / signal, for example, including but not limited to: an uplink sounding reference signal (called SRS by NR), an uplink demodulation reference signal (called DMRS by NR), an uplink phase tracking reference signal (called PTRS by NR), an uplink control channel - a physical uplink control channel (called PUCCH by NR), an uplink data channel - a physical uplink shared channel (called PUSCH by NR), etc.

[0099] Different types or uses of the same channel or signal can use beam / QCL information corresponding to different TCIs. The channel or channel type / use corresponding to the TCI indicated by the first information can be determined based on factors such as the time domain characteristics of the channel or signal (such as periodic, semi-continuous, non-periodic, etc.), information attributes (such as public information, proprietary information, broadcast multicast information, unicast information, etc.), and uses (such as channel measurement, beam training, time-frequency synchronization, etc.).

[0100] For example, the PDCCH that carries common control information needs to be received by multiple UEs and is usually transmitted using a wide beam; whereas the PDCCH that carries UE-specific control information only needs to be received by the UE and is transmitted using a narrow beam targeted at the UE.

[0101] The broadcast / multicast data channel PDSCH needs to be received by multiple UEs, while the unicast data channel PDSCH only needs to be received by the UE itself, so the beams used will also be different.

[0102] For example, the CSI-RS used for beam scanning and the CSI-RS used to measure downlink channel information in the current beam may use different beams. The SRS used for beam training and the SRS used to measure uplink channel information in the current beam (used for codebook or non-codebook SRS, and antenna switching) may also use different beams.

[0103] 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.

[0104] After the terminal device receives the first information, it can use the corresponding TCI to transmit a certain channel or signal, or a certain channel or signal of a certain type or purpose, based on the TCI contained in the first information, the channel or signal corresponding to each TCI, or the channel or channel type or purpose corresponding to each TCI.

[0105] As an example, the first information in an embodiment of the present application may include at least one item of {TCI1, ..., TCIM, TCI list1, ..., TCI listN}, and indicate the channel / signal to which each TCI or TCI list applies, or the type / purpose of the channel / signal, as shown in Table 1:

[0106] Table 1

[0107] The TCI shown in Table 1 is a joint TCI mode, and the uplink and downlink TCIs are the same.

[0108] Then, after receiving the first information, the terminal device may perform the following transmission operations:

[0109] Use TCI1 to receive control channel type 1 or broadcast data channel;

[0110] Use TCI2 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;

[0111] Use TCI3, TCI4, TCI5, and TCI6 to receive four CSI-RS resources of CSI-RS type 2 respectively;

[0112] Two SRS resources of SRS type 2 are sent using TCI4 and TCI7 respectively.

[0113] Optionally, the method further includes:

[0114] The network side device sends target indication information to the terminal device.

[0115] The target indication information includes at least one of the following:

[0116] a first indication, where the first indication is used to indicate a channel or signal corresponding to the at least one transmission configuration indication in the first information;

[0117] A second indication, where the second indication is used to indicate the type or usage of a channel or signal corresponding to the at least one transmission configuration indication in the first information.

[0118] In an embodiment of the present application, after the network side device indicates the first information to the terminal device, it can also indicate to the terminal device through target indication information the channel or signal to which the TCI contained in the first information is applicable, and / or indicate the type or purpose of the channel / signal to which the TCI contained in the first information is applicable.

[0119] After receiving the target indication information, when a 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 a terminal device sends or receives a channel or signal of a certain type or purpose, 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 the type or purpose of the channel.

[0120] Optionally, the network side device sending target indication information to the terminal device includes:

[0121] The network side device sends a first signaling to the terminal device, where the first signaling carries the target indication information.

[0122] The first signaling includes at least one of the following:

[0123] signaling for indicating the first information;

[0124] Signaling used to indicate at least one transmission configuration indication in the first information.

[0125] In the embodiment of the present application, the target indication information may be carried in signaling used to indicate the first information, or may be carried in signaling used to indicate one or more TCIs in the first information. For example, the target indication information may be carried in RRC signaling used to configure the first information or TCI, or in MAC signaling used to activate the first information or TCI, or in DCI used to indicate the first information or TCI, etc.

[0126] Of course, the network side device may also use other signaling to send target indication information to the terminal device separately.

[0127] Optionally, the channel or signal and the transmission configuration indication satisfy at least one of the following:

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

[0129] The transmission configuration indications corresponding to other channels or signals except the channel or signal included in the first information remain unchanged;

[0130] The type or usage of the channel or signal included in the first information is indicated by the transmission configuration indicated by the first information;

[0131] The transmission configuration indications corresponding to the channel or signal types or uses other than the type or use included in the first information remain unchanged.

[0132] In an embodiment of the present application, the network-side device may update the TCI corresponding to the channel or signal, or update the TCI corresponding to the type or purpose of the channel or signal, based on the first information. The channel or signal, or the type or purpose of the channel or signal, indicated in the first information, uses the TCI indicated in the first information; other channels or signals, or other types or purposes of channels or signals, continue to use the original TCI.

[0133] For example, it is assumed that after the network side device indicates the first information shown in Table 1 through DCI, it again indicates the first information shown in Table 2:

[0134] Table 2

[0135] Then, the terminal device performs the following transmission operations:

[0136] Still use TCI1 to receive control channel type 1 or broadcast data channel;

[0137] Use TCI10 to receive control channel type 2, unicast downlink data channel, CSI-RS type 1, and transmit uplink control channel, uplink data channel or SRS type 1;

[0138] TCI3, TCI4, TCI5, and TCI6 are still used to receive the four CSI-RS resources of CSI-RS type 2 respectively;

[0139] TCI4 and TCI7 are still used to send two SRS resources of SRS type 2 respectively.

[0140] As another example, assume that the first information indicated by the network-side device includes at least one item of {TCI1, ..., TCIM, TCI list1, ..., TCI listN}, and indicates the channel / signal to which each TCI or TCI list applies, or the type / purpose of the channel / signal, as shown in Table 3 (independent TCI mode, uplink and downlink TCI are different):

[0141] Table 3

[0142] Then, after receiving the first information, the terminal device performs the following transmission operations:

[0143] Use TCI1 to receive control channel type 1 or broadcast data channel;

[0144] Use TCI2 to receive control channel type 2, unicast downlink data channel, and CSI-RS type 1;

[0145] Use TCI4 to send uplink control channel, uplink data channel or SRS type 1;

[0146] Use TCI3, TCI4, TCI5, and TCI6 to receive four CSI-RS resources of CSI-RS type 2 respectively;

[0147] Two SRS resources of SRS type 2 are sent using TCI4 and TCI7 respectively.

[0148] Assume that after the network side device indicates the first information shown in Table 3 through DCI, it again indicates the first information shown in Table 4:

[0149] Table 4

[0150] Then, the terminal device performs the following transmission operations:

[0151] Still use TCI1 to receive control channel type 1 or broadcast data channel;

[0152] Still using TCI2 to receive control channel type 2, unicast downlink data channel, CSI-RS type 1;

[0153] Use TCI11 to send uplink control channel, uplink data channel or SRS type 1;

[0154] TCI3, TCI4, TCI5, and TCI6 are still used to receive the four CSI-RS resources of CSI-RS type 2 respectively;

[0155] TCI4 and TCI7 are still used to send two SRS resources of SRS type 2 respectively.

[0156] Optionally, the network-side device indicates to the terminal device the first information, including at least one of the following:

[0157] 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;

[0158] The network side device indicates at least one first information included in at least one first information group to the terminal device.

[0159] In a multi-TRP scenario, the network side device can also indicate a first information group to the terminal device, each first information group containing at least one first information.

[0160] 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 signalings.

[0161] Optionally, the network-side device indicates to the terminal device at least one first information group, including:

[0162] 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.

[0163] In a possible application scenario, the network side device can configure the correspondence between the first information group and the first information in advance, and then indicate the first information group to the terminal device through the second signaling. After the terminal device receives the second signaling, it can determine the first information contained in the first information group indicated by the second signaling based on the correspondence between the first information group and the first information.

[0164] Optionally, at least one of the first information groups indicated by the second signaling is valid, or all the first information contained in the first information group indicated by the second signaling is valid.

[0165] If the network side device indicates one or more first information groups through the second signaling, the terminal device may consider that each first information group indicated by the second signaling is effective after the effective time is reached, or that all first information contained in the first information group indicated in the second signaling is effective after the effective time is reached.

[0166] Optionally, the network-side device indicates to the terminal device at least one first information included in at least one first information group, including:

[0167] The network side device sends a third signaling to the terminal device; the third signaling is used to indicate the first information.

[0168] In a case where one of the first information groups indicated by the second signaling is valid, the first information indicated by the third signaling is the first information in the one of the first information groups indicated by the second signaling;

[0169] When at least two of the first information groups indicated by the second signaling are effective, the first information indicated by the third signaling is the first information in the at least two first information groups indicated by the second signaling, and the first information contained 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.

[0170] For example, when the second signaling indicates a first information group, the UE uses the first information in the first information group indicated by the third signaling to receive or send signals. In this way, changes 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 in the first information group to receive or send signals, thereby achieving simultaneous reception or transmission of multiple TCIs within the TRP group; when the 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 in the at least two first information groups to receive or send signals, thereby achieving simultaneous reception or transmission of TCIs between TRP groups.

[0171] Optionally, the method further includes:

[0172] 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 group indicated by the second signaling and the first information indicated by the third signaling.

[0173] When the second signaling indicates at least two first information groups, the network side device can indicate to the terminal device through a third indication the correspondence between the first information group indicated by the second signaling and the first information indicated by the third signaling, so that the terminal device can determine the first information contained in each first information group indicated by the second signaling.

[0174] Optionally, the network-side device indicates to the terminal device at least one first information included in at least one first information group, including:

[0175] 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.

[0176] Optionally, the first signaling further includes a fourth indication, where the fourth indication is used to indicate the first information group to which the first information belongs.

[0177] In an embodiment of the present application, the network side device may also indicate the first information group and the first information contained in the first information group to the terminal device at the same time through the fourth signaling or the first signaling.

[0178] It should be noted that the first signaling, second signaling, third signaling and fourth signaling in the embodiments of the present application can all be RRC signaling, MAC signaling or DCI.

[0179] Optionally, the method further includes:

[0180] The network-side device is configured with at least one first configuration pool, where the first configuration pool includes at least one first information.

[0181] In the first configuration pool, the first information and the transmission configuration indication satisfy at least one of the following:

[0182] The first information and the transmission configuration indication use the same group index number;

[0183] The first information and the transmission configuration indication use different index numbers.

[0184] In an embodiment of the present application, the network side device can also configure a first configuration pool, which is a TCI state pool. It can include the first information in the embodiment of the present application, and can also include other TCIs other than the TCI included in the first information.

[0185] In the first configuration pool, the first information and the TCI it contains may use the same group of index numbers, or may use different index numbers (the first information and the TCI are numbered separately).

[0186] Optionally, the network-side device configures at least one first configuration pool, including:

[0187] The network-side device configures the at least one first configuration pool in the public configuration information.

[0188] The first configuration pool in the embodiment of the present application may be located in the public configuration information outside the serving cell configuration information, so that all cells can access the first configuration pool.

[0189] Optionally, the method further includes:

[0190] 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 indications or the first information or the first information group corresponds to at least one component carrier or bandwidth part.

[0191] In the embodiment of the present application, the network side device may further configure a corresponding component carrier CC or bandwidth part BWP for each TCI, or each first information, or each first information group.

[0192] For example, the network device configures a first configuration pool in which each TCI state configures one or more CCs or BWPs using that TCI state. After receiving a TCI state activation or indication for a CC or BWP, the UE interprets the TCI state sequence number of the CC or BWP based on the TCI state number associated with each CC or BWP configured for that TCI state in the TCI state pool.

[0193] As an example, the configuration of a first configuration pool is as follows:

[0194] TCI state1: CC1, CC2

[0195] TCI state2: CC1

[0196] TCI state3: CC1, CC3

[0197] TCI state4: CC2

[0198] TCI state5: CC2, CC3

[0199] Then, the TCI state corresponding to each CC can be: (the TCI state number in the brackets is the TCI state number in the TCI state pool)

[0200] The TCI states of CC1 are: TCI state1 (TCI state1), TCI state2 (TCI state2), TCI state3 (TCI state3).

[0201] The TCI states of CC2 are: TCI state1 (TCI state1), TCI state2 (TCI state4), TCI state3 (TCI state5).

[0202] The TCI states of CC3 are: TCI state1 (TCI state3), TCI state2 (TCI state5).

[0203] When a TCI state is indicated on a certain CC, one or more CCs corresponding to the TCI state use the TCI state together.

[0204] In summary, the embodiment of the present application provides a transmission configuration method, and the network side device can indicate the TCI corresponding to different channels or signals to the terminal device through the first information, 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 selects 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 use the first information to uniformly indicate the TCI for multiple channels or signals, and / or multiple types or uses of the same channel or signal, without distinguishing 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.

[0205] The present application also provides another transmission configuration method. Referring to FIG3, a flow chart of another transmission configuration method provided by the present application is shown. The method is applied to a terminal device, as shown in FIG3, and the method may specifically include:

[0206] Step 201: The terminal device obtains first information indicated by the network side device;

[0207] Step 202: The terminal device transmits based on the first information.

[0208] The first information includes at least one transmission configuration indication; the transmission configuration indication satisfies at least one of the following:

[0209] Each transmission configuration indication corresponds to at least one channel or signal;

[0210] Each transmission configuration indicates at least one type or usage of at least one channel or signal.

[0211] The transmission configuration method provided in the embodiment of the present 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 the 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.

[0212] The channel or signal corresponding to the TCI indicated by the first information may be a downlink channel / signal, for example, including but not limited to: a downlink synchronization signal block (called SSB by NR), a downlink tracking reference signal (called TRS by NR), a downlink channel state information reference signal (called CSI-RS by NR), a downlink demodulation reference signal (called DMRS by NR), a downlink phase tracking reference signal (called PTRS by NR), a downlink control channel - a physical downlink control channel (called PDCCH by NR), a downlink data channel - a physical downlink shared channel (called PDSCH by NR), etc. Alternatively, the channel or signal corresponding to the TCI indicated by the first information may also be an uplink channel / signal, for example, including but not limited to: an uplink sounding reference signal (called SRS by NR), an uplink demodulation reference signal (called DMRS by NR), an uplink phase tracking reference signal (called PTRS by NR), an uplink control channel - a physical uplink control channel (called PUCCH by NR), an uplink data channel - a physical uplink shared channel (called PUSCH by NR), etc.

[0213] Different types or uses of the same channel or signal can use beam / QCL information corresponding to different TCIs. The channel or channel type / use corresponding to the TCI indicated by the first information can be determined based on factors such as the time domain characteristics of the channel or signal (such as periodic, semi-continuous, non-periodic, etc.), information attributes (such as public information, proprietary information, broadcast multicast information, unicast information, etc.), and uses (such as channel measurement, beam training, time-frequency synchronization, etc.).

[0214] For example, the PDCCH that carries common control information needs to be received by multiple UEs and is usually transmitted using a wide beam; whereas the PDCCH that carries UE-specific control information only needs to be received by the UE and is transmitted using a narrow beam targeted at the UE.

[0215] The broadcast / multicast data channel PDSCH needs to be received by multiple UEs, while the unicast data channel PDSCH only needs to be received by the UE itself, so the beams used will also be different.

[0216] For example, the CSI-RS used for beam scanning and the CSI-RS used to measure downlink channel information in the current beam may use different beams. The SRS used for beam training and the SRS used to measure uplink channel information in the current beam (used for codebook or non-codebook SRS, and antenna switching) may also use different beams.

[0217] After the terminal device receives the first information, it can use the corresponding TCI to transmit a certain channel or signal, or a certain channel or signal of a certain type or purpose, based on the TCI contained in the first information, the channel or signal corresponding to each TCI, or the channel or channel type or purpose corresponding to each TCI.

[0218] Optionally, the method further includes:

[0219] The terminal device receives the target indication information sent by the network side device.

[0220] The target indication information includes at least one of the following:

[0221] a first indication, where the first indication is used to indicate a channel or signal corresponding to the at least one transmission configuration indication in the first information;

[0222] A second indication, where the second indication is used to indicate the type or usage of a channel or signal corresponding to the at least one transmission configuration indication in the first information.

[0223] In an embodiment of the present application, after the network side device indicates the first information to the terminal device, it can also indicate to the terminal device through target indication information the channel or signal to which the TCI contained in the first information is applicable, and / or indicate the type or purpose of the channel / signal to which the TCI contained in the first information is applicable.

[0224] After receiving the target indication information, when a 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 a terminal device sends or receives a channel or signal of a certain type or purpose, 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 the type or purpose of the channel.

[0225] Optionally, the terminal device receives the target indication information sent by the network side device, including:

[0226] The terminal device receives a first signaling sent by the network side device, where the first signaling carries the target indication information.

[0227] The first signaling includes at least one of the following:

[0228] signaling for indicating the first information;

[0229] Signaling used to indicate at least one transmission configuration indication in the first information.

[0230] In the embodiment of the present application, the target indication information may be carried in signaling used to indicate the first information, or may be carried in signaling used to indicate one or more TCIs in the first information. For example, the target indication information may be carried in RRC signaling used to configure the first information or TCI, or in MAC signaling used to activate the first information or TCI, or in DCI used to indicate the first information or TCI, etc.

[0231] Of course, the network side device may also use other signaling to send target indication information to the terminal device separately.

[0232] Optionally, the channel or signal and the transmission configuration indication satisfy at least one of the following:

[0233] The channel or signal included in the first information uses the transmission configuration indicated by the first information;

[0234] The transmission configuration indications corresponding to other channels or signals except the channel or signal included in the first information remain unchanged;

[0235] The type or usage of the channel or signal included in the first information is indicated by the transmission configuration indicated by the first information;

[0236] The transmission configuration indications corresponding to the channel or signal types or uses other than the type or use included in the first information remain unchanged.

[0237] In an embodiment of the present application, a terminal device may update the TCI corresponding to a channel or signal, or update the TCI corresponding to the type or purpose of the channel or signal, based on the first information. The channel or signal, or the type or purpose of the channel or signal, indicated in the first information, uses the TCI indicated in the first information; other channels or signals, or other types or purposes of channels or signals, continue to use the original TCI.

[0238] Optionally, the first information obtained by the terminal device from the network side device includes at least one of the following:

[0239] 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;

[0240] The terminal device determines at least one first information contained in at least one first information group indicated by the network side device.

[0241] In a multi-TRP scenario, the network side device can also indicate a first information group to the terminal device, each first information group containing at least one first information.

[0242] 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 signalings.

[0243] Optionally, the terminal device determines at least one first information group indicated by the network side device, including:

[0244] 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.

[0245] In a possible application scenario, the network side device can configure the correspondence between the first information group and the first information in advance, and then indicate the first information group to the terminal device through the second signaling. After the terminal device receives the second signaling, it can determine the first information contained in the first information group indicated by the second signaling based on the correspondence between the first information group and the first information.

[0246] Optionally, at least one of the first information groups indicated by the second signaling is valid, or all the first information contained in the first information group indicated by the second signaling is valid.

[0247] If the network side device indicates one or more first information groups through the second signaling, the terminal device may consider that each first information group indicated by the second signaling is effective after the effective time is reached, or that all first information contained in the first information group indicated in the second signaling is effective after the effective time is reached.

[0248] Optionally, the terminal device determines at least one first information included in at least one first information group indicated by the network side device, including:

[0249] The terminal device receives a third signaling sent by the network side device; the third signaling is used to indicate the first information.

[0250] In a case where one of the first information groups indicated by the second signaling is valid, the first information indicated by the third signaling is the first information in the one of the first information groups indicated by the second signaling;

[0251] When at least two of the first information groups indicated by the second signaling are effective, the first information indicated by the third signaling is the first information in the at least two first information groups indicated by the second signaling, and the first information contained 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.

[0252] For example, when the second signaling indicates a first information group, the UE uses the first information in the first information group indicated by the third signaling to receive or send signals. In this way, changes 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 in the first information group to receive or send signals, thereby achieving simultaneous reception or transmission of multiple TCIs within the TRP group; when the 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 in the at least two first information groups to receive or send signals, thereby achieving simultaneous reception or transmission of TCIs between TRP groups.

[0253] Optionally, the method further includes:

[0254] 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.

[0255] When the second signaling indicates at least two first information groups, the network-side device may indicate to the terminal device, through a third indication, the correspondence between the first information group indicated by the second signaling and the first information indicated by the third signaling. Based on the third indication and the first information indicated by the third signaling, the terminal device may determine the first information contained in each first information group indicated by the second signaling.

[0256] Optionally, the terminal device determines at least one first information included in at least one first information group indicated by the network side device, including:

[0257] 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 contained in the first information group.

[0258] Optionally, the first signaling further includes a fourth indication, where the fourth indication is used to indicate the first information group to which the first information belongs.

[0259] In an embodiment of the present application, the network side device may also indicate the first information group and the first information contained in the first information group to the terminal device at the same time through the fourth signaling or the first signaling.

[0260] Optionally, the method further includes:

[0261] 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 indications or the first information or the first information group corresponds to at least one component carrier or bandwidth part.

[0262] In this embodiment of the present application, the network device may further configure a corresponding component carrier CC or bandwidth part BWP for each TCI, each first information, or each first information group. After receiving the fifth indication, the terminal device may determine the TCI corresponding to each CC or BWP.

[0263] In summary, the embodiment of the present application provides a transmission configuration method, and the terminal device can determine the TCI corresponding to different channels or signals, and / or the TCI corresponding to different types or uses of the same channel or signal based on the first information indicated by the network side device, thereby selecting 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, as well as multiple types or uses of the same channel or signal, without distinguishing 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.
