技术领域Technical field

本公开涉及通信技术领域，尤其涉及一种指示方法、终端及网络侧设备。The present disclosure relates to the field of communication technology, and in particular to an indication method, terminal and network side equipment.

背景技术Background technique

多点协作传输(Coordinated Multiple Points Transmission/Reception，CoMP)是指地理位置上分离的多个传输接收点(Transmission Reception Point，TRP)协同参与为一个终端的数据传输或者联合接收一个终端发送的数据。Coordinated Multiple Points Transmission/Reception (CoMP) refers to the coordinated participation of multiple transmission reception points (Transmission Reception Points, TRP) separated geographically in data transmission for one terminal or joint reception of data sent by one terminal.

其中，TRP的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的接收波束方向可以通过传输配置指示器状态(Transmission Configuration Indicator State，TCI State)配置，通常通过无线资源控制(Radio Resource Control，RRC)信令可配置多个TCI State(最多可达128个)，通过媒体访问控制(Media Access Control，MAC)控制元素(Control Element，CE)最多可激活其中的8个TCI State，最终由下行控制信息(Downlink Control Information，DCI)指示终端实际采用的1个TCI State。Among them, the receiving beam direction of the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) of the TRP can be configured through the Transmission Configuration Indicator State (TCI State), usually through Radio Resource Control (RRC). The signaling can be configured with multiple TCI states (up to 128), and up to 8 TCI states can be activated through the Media Access Control (MAC) control element (CE), and finally the downlink control information (Downlink Control Information, DCI) indicates 1 TCI State actually adopted by the terminal.

由于多点协作传输同时存在多个TRP的PDSCH，不同TRP的PDSCH传输方向可能不同，因此需要指示终端接收不同TRP使用的TCI State。相关技术中，参与多点协作传输的多个TRP中的每个TRP均会通过各自的物理下行控制信道(Physical Downlink Control Channel，PDCCH)向终端指示其使用的TCI State。然而，这种多点协作传输方式属于非理想回传场景，多个TRP之间会存在一定的交互时延，进而会对终端业务的信噪比或吞吐率造成一定影响。Since there are PDSCHs of multiple TRPs in coordinated multipoint transmission at the same time, the transmission directions of PDSCHs of different TRPs may be different, so the terminal needs to be instructed to receive the TCI State used by different TRPs. In related technologies, each of the multiple TRPs participating in coordinated multi-point transmission will indicate the TCI State it uses to the terminal through its respective Physical Downlink Control Channel (PDCCH). However, this kind of coordinated multipoint transmission is a non-ideal backhaul scenario, and there will be a certain interaction delay between multiple TRPs, which in turn will have a certain impact on the signal-to-noise ratio or throughput rate of terminal services.

具体实施方式Detailed ways

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

本公开实施例中，提出了一种指示方法、终端及网络侧设备，以解决相关多点协作传输方式中，多个TRP之间存在一定的交互时延，使得终端的信噪比或吞吐率受到影响的问题。In the embodiments of the present disclosure, an indication method, terminal, and network-side equipment are proposed to solve the problem of a certain interaction delay between multiple TRPs in the related coordinated multi-point transmission mode, which makes the terminal’s signal-to-noise ratio or throughput rate Issues affected.

参见图1，图1是本公开实施例提供的一种指示方法的流程图，如图1所示，所述方法包括以下步骤：Referring to Fig. 1, Fig. 1 is a flowchart of an indication method provided by an embodiment of the present disclosure. As shown in Fig. 1, the method includes the following steps:

步骤101、接收至少一个携带第一指示信息的MAC CE，用于指示N个网络侧设备的TCI State的激活/去激活，所述N为大于或等于2的整数。Step 101: Receive at least one MAC CE carrying first indication information, which is used to indicate the activation/deactivation of the TCI State of N network side devices, where N is an integer greater than or equal to 2.

本实施例中，所述指示方法可以应用于终端，上述接收至少一个携带第一指示信息的MAC CE可以是接收网络侧设备通过PDCCH发送的一个或多个MAC CE，且每个所述MAC CE均携带有第一指示信息。In this embodiment, the indication method may be applied to the terminal. The foregoing receiving at least one MAC CE carrying the first indication information may be receiving one or more MAC CEs sent by the network-side device through the PDCCH, and each MAC CE Both carry the first indication information.

本公开具体实施例中，应当理解的是，指示N个网络侧设备的TCI State的激活/去激活包括了如下的两种情形：In the specific embodiments of the present disclosure, it should be understood that indicating the activation/deactivation of the TCI State of N network-side devices includes the following two scenarios:

指示N个网络侧设备的激活的TCI State；TCI State indicating the activation of N network side devices;

指示N个网络侧设备的去激活的TCI State。TCI State indicating the deactivation of N network side devices.

具体地，当所述MAC CE的数量为一个时，该MAC CE中携带的第一指示信息可用于指示N个网络侧设备的TCI State的激活/去激活，当所述MAC CE的数量为多个时，每个MAC CE携带的第一指示信息可分别用于指示某一个网络侧设备的TCI State的激活/去激活，从而通过多个所述MAC CE中的第一指示信息的集合，可实现指示多个网络侧设备的TCI State的激活/去激活，如通过N个MAC CE，可指示N个网络侧设备的TCI State的激活/去激活。Specifically, when the number of MAC CE is one, the first indication information carried in the MAC CE can be used to indicate the activation/deactivation of the TCI State of N network-side devices. When the number of MAC CEs is large At this time, the first indication information carried by each MAC CE can be used to indicate the activation/deactivation of the TCI State of a certain network-side device, so that the collection of first indication information in multiple MAC CEs can be It realizes the activation/deactivation of the TCI State indicating multiple network-side devices. For example, through N MAC CEs, the activation/deactivation of the TCI State of N network-side devices can be indicated.

其中，所述N个网络侧设备可以是参与多点协作传输的多个TRP(后文均使用TRP来表示参与多点协作传输的网络侧设备)中的部分TRP或全部TRP，但也可以是其他能够执行联合传输的网络设备，所述N为大于或等于2的整数。Wherein, the N network-side devices may be part of or all TRPs in multiple TRPs participating in coordinated multipoint transmission (TRP is used to indicate network-side devices participating in coordinated multipoint transmission), but may also be For other network devices capable of performing joint transmission, the N is an integer greater than or equal to 2.

具体地，MAC CE中可以通过指示信息指示TCI state状态应用于1个网络侧设备，还是应用于N个网络侧设备。Specifically, the MAC CE may indicate whether the TCI state is applied to one network-side device or to N network-side devices through indication information.

更具体地，MAC CE中可以通过所述指示信息指示所述第一指示信息中的部分字段用于指示1个网络侧设备的TCI state激活/去激活，还是该部分字段用于指示N个网络侧设备的TCI state激活/去激活。More specifically, the MAC CE may indicate through the indication information that part of the field in the first indication information is used to indicate the activation/deactivation of the TCI state of one network-side device, or whether this part of the field is used to indicate N networks The TCI state of the side device is activated/deactivated.

上述TCI state可以是终端接收数据的TCI state或网络侧发送数据的TCI state；也可以是终端发送数据的TCI state或网络侧接收数据的TCI state。The above-mentioned TCI state may be the TCI state where the terminal receives data or the TCI state where the network side sends data; it may also be the TCI state where the terminal sends data or the TCI state where the network side receives data.

具体地，上述MAC CE也可以只用于指示N个网络侧设备的TCI state激活/去激活。为了与指示1个网络侧设备的TCI state激活/去激活的MAC CE区分，在指示N个网络侧设备的TCI state激活/去激活的MAC CE中还可以通过指示比特进行区分，该指示比特用来说明该MAC CE用于N个网络侧设备的TCI state激活/去激活。Specifically, the above-mentioned MAC CE may also only be used to indicate the activation/deactivation of the TCI state of N network side devices. In order to distinguish from the MAC CE indicating the activation/deactivation of the TCI state of a network-side device, the MAC CE indicating the activation/deactivation of the TCI state of the N network-side devices can also be distinguished by an indicator bit. To illustrate that the MAC CE is used to activate/deactivate the TCI state of N network side devices.

上述TCI State用于指示数据与参考符号之间的准共址(Quasi Co-Location，QCL)关系，即指发送端发送数据与参考符号的发送波束方向相同或者接收端接收数据与参考符号的接收波束方向相同。The above-mentioned TCI State is used to indicate the Quasi Co-Location (QCL) relationship between the data and the reference symbol, that is, the transmission beam direction of the data sent by the transmitter is the same as that of the reference symbol, or the receiving end receives the data and the reference symbol. The beam directions are the same.

上述TCI State的激活/去激活可以包括TCI State的激活状态或去激活状态，具体地，所述N个TRP中的每个TRP均可以配置多个TCI State，且可以激活/去激活其中的部分TCI State，TRP可通过所述MAC CE向终端指示参与多点协作传输的N个TRP中的每个TRP的TCI State中，哪些TCI State是激活/去激活状态。The activation/deactivation of the aforementioned TCI State may include the activation state or the deactivation state of the TCI State. Specifically, each TRP of the N TRPs can be configured with multiple TCI States, and some of them can be activated/deactivated TCI State, the TRP can indicate to the terminal through the MAC CE, which TCI State of each of the N TRPs participating in coordinated multipoint transmission is in the activated/deactivated state.

这样，TRP可以向终端联合指示参与多点协作传输的N个TRP的TCI State的激活/去激活，从而终端只需通过一个PDCCH接收所述MAC CE中的第一指示信息，以获知所述N个TRP的TCI State的激活/去激活状态。In this way, the TRP can jointly indicate to the terminal the activation/deactivation of the TCI State of the N TRPs participating in coordinated multi-point transmission, so that the terminal only needs to receive the first indication information in the MAC CE through one PDCCH to learn the N The activation/deactivation state of the TCI State of a TRP.

本公开具体实施例中，需要通过MAC CE中携带的第一指示信息来指示N个网络侧设备的TCI State的激活/去激活，而具体通过所述第一指示信息来指示N个网络侧设备的TCI State的激活/去激活的方式多种多样，分别描述如下。In the specific embodiment of the present disclosure, it is necessary to indicate the activation/deactivation of the TCI State of N network-side devices through the first indication information carried in the MAC CE, and specifically indicate the N network-side devices through the first indication information There are many ways to activate/deactivate the TCI State, which are described as follows.

可选的，所述第一指示信息包括以下至少之一：Optionally, the first indication information includes at least one of the following:

第一指示字段，用于指示TCI State组合/配对的激活/去激活，所述TCI State组合/配对中包括G个激活/去激活的TCI State，所述G为大于或等于2的整数；The first indication field is used to indicate the activation/deactivation of the TCI State combination/pairing. The TCI State combination/pairing includes G activated/deactivated TCI States, and the G is an integer greater than or equal to 2;

第二指示字段，用于指示TCI State的激活/去激活。The second indication field is used to indicate the activation/deactivation of the TCI State.

第一种实施方式中，可以采用组合/配对指示的方式来指示参与多点协作传输的N个TRP的TCI State状态，尤其是当所述至少一个MAC CE的数量为一个时，通过组合/配对指示的方式，可以实现仅通过一个MAC CE中携带的第一指示信息来指示多个TRP的TCI State状态。具体地，所述第一指示信息可包括用于指示TCI State组合/配对的激活/去激活的第一指示字段，也就是说所述第一指示字段可指示TCI State组合/配对的激活或去激活状态，每组TCI State组合/配对中包括G个激活/去激活的TCI State，所述G个激活/去激活的TCI State与所述N个TRP中的G个TRP一一对应，所述G等于N时，所述第一指示字段可以指示所述N个TRP的激活/去激活的TCI State。In the first implementation manner, a combination/pairing indication can be used to indicate the TCI State status of N TRPs participating in coordinated multi-point transmission, especially when the number of the at least one MAC CE is one, through combination/pairing In the manner of indication, it is possible to indicate the TCI State states of multiple TRPs only through the first indication information carried in one MAC CE. Specifically, the first indication information may include a first indication field for indicating activation/deactivation of TCI State combination/pairing, that is to say, the first indication field may indicate activation or deactivation of TCI State combination/pairing. Activation state, each TCI State combination/pairing includes G activated/deactivated TCI States, and the G activated/deactivated TCI States correspond to G TRPs out of the N TRPs. When G is equal to N, the first indication field may indicate the TCI State of activation/deactivation of the N TRPs.

具体地，由于每个TRP均可以配置多个TCI State，且每个TRP又可以激活/去激活其中不同的TCI State，这样，随每个TRP使用各自配置的TCI State中的不同激活/去激活的TCI State，所述N个TRP的TCI State可以形成多组不同的激活/去激活的TCI State组合/配对。例如，2个TRP中，每个TRP配置有128个TCI State，这样，每个TRP均可以从各自的128个TCI State中选择出1个或多个TCI State进行激活/去激活，从而2个TRP的TCI State可以形成128×128种TCI State组合/配对。Specifically, because each TRP can be configured with multiple TCI states, and each TRP can activate/deactivate different TCI states, so that each TRP uses different activation/deactivation in the configured TCI State The TCI State of the N TRPs may form multiple sets of different activated/deactivated TCI State combinations/pairs. For example, in 2 TRPs, each TRP is configured with 128 TCI States. In this way, each TRP can select one or more TCI States from its 128 TCI States for activation/deactivation, thus 2 The TCI State of TRP can form 128×128 TCI State combinations/pairs.

而对于每组TCI State组合/配对，可以选择采用1个指示位(如1个比特 bit)来指示该组TCI State组合/配对是否被激活或去激活，例如，比特置1表示对应的TCI State组合/配对被激活，即该组TCI State组合/配对中的每个TCI State均被激活，比特置0表示对应的TCI State组合/配对未被激活，即该组TCI State组合/配对中的每个TCI State均未被激活；或者也可以采用N个指示位(如N个比特bit)来分别指示该组TCI State组合/配对中的N个TCI State是否被激活或去激活，即对于一组TCI State组合/配对中的N个TCI State，可以分别单独指示其中的某个TCI State是否被激活或去激活，例如，使用10表示TCI State组合/配对中与TRP0对应的TCI State被激活，与TRP1对应的TCI State未被激活。也就是说，所述第一指示字段可以包括L个比特用于指示TCI State组合/配对的激活/去激活，所述L为大于或等于1的整数。For each TCI State combination/pairing, you can choose to use 1 indicator bit (such as 1 bit) to indicate whether the TCI State combination/pairing of the group is activated or deactivated. For example, a bit is set to 1 to indicate the corresponding TCI State. The combination/pairing is activated, that is, each TCI State in the group of TCI State combinations/pairs is activated, and the bit is set to 0 to indicate that the corresponding TCI State combination/pairing is not activated, that is, each TCI State combination/pairing in the group N TCI States are not activated; or N indicator bits (such as N bits) can be used to indicate whether the N TCI States in the group of TCI State combinations/pairs are activated or deactivated, that is, for a group The N TCI States in the TCI State combination/pair can separately indicate whether a certain TCI State is activated or deactivated. For example, use 10 to indicate that the TCI State corresponding to TRP0 in the TCI State combination/pair is activated, and The TCI State corresponding to TRP1 is not activated. That is, the first indication field may include L bits for indicating activation/deactivation of the TCI State combination/pairing, and the L is an integer greater than or equal to 1.

或者，对于每组TCI State组合/配对，还可以采用C个指示位(如C个比特bit)来指示该组TCI State组合/配对中对应N个TRP的处于激活/去激活状态的TCI State ID或比特索引，可共使用R×C个指示位来指示R组TCI State组合/配对的TCI State ID或比特索，所述R为大于或等于1的整数。例如，可使用C个bit中的部分bit来指示TRP0中的1个TCI State ID，使用C个bit中的剩余bit来指示TRP1中的1个TCI State ID，这C个bit便构成一个TCI state组合。Or, for each TCI State combination/pairing, C indicator bits (such as C bits) can also be used to indicate the TCI State ID corresponding to the N TRPs in the TCI State combination/pairing in the activated/deactivated state. Or bit index, a total of R×C indicator bits can be used to indicate the TCI State ID or bit index of the R group TCI State combination/pair, where R is an integer greater than or equal to 1. For example, some of the C bits can be used to indicate a TCI State ID in TRP0, and the remaining bits in the C bits can be used to indicate a TCI State ID in TRP1. These C bits constitute a TCI state. combination.

该实施方式中，对于上述采用1个指示位来指示每组TCI State组合/配对的激活或去激活状态的组合/配对指示方式，还可以有两种不同的指示方式，其一为：所述第一指示字段采用bitmap方式，指示激活/去激活所述N个TRP的TCI State所形成的所有TCI State组合/配对中的每组TCI State组合，且每一组TCI State组合/配对可以使用1个比特bit来指示其激活/去激活状态。In this embodiment, for the above-mentioned combination/pairing indication method that uses 1 indicator bit to indicate the activation or deactivation state of each group of TCI State combination/pairing, there may also be two different indication methods, one of which is: The first indication field adopts a bitmap mode to indicate all TCI State combinations/pairs formed by activating/deactivating the TCI State of the N TRPs, and each TCI State combination/pairing can use 1 One bit to indicate its activation/deactivation status.

例如，以2个TRP进行协作传输为例，每个TRP配置有128个TCI State，2个TRP的TCI State可以形成128×128种TCI State组合，每一组TCI State组合可以使用1个bit来指示其激活/去激活状态，从而可使用128×128个bit来指示激活/去激活所述128×128种TCI State组合中的每组TCI State组合；且具体地，若某组TCI State组合中的每个TCI State都被激活，则该组TCI State组合对应的bit被置1，表示该组TCI State组合中的每个TCI State都被激活，也就是说，该组TCI State组合中分别与所述2个TRP一一对应的2个TCI State 被激活；若某组TCI State组合对应的bit被置0，表示去激活该组TCI State组合，该组TCI State组合中分别与所述2个TRP一一对应的2个TCI State中至少一个未被激活。For example, taking two TRPs for cooperative transmission as an example, each TRP is configured with 128 TCI States, and the TCI States of 2 TRPs can form 128×128 TCI State combinations. Each TCI State combination can use 1 bit to Indicate its activation/deactivation state, so that 128×128 bits can be used to indicate the activation/deactivation of each TCI State combination in the 128×128 TCI State combinations; and specifically, if a certain group of TCI State combinations is If each TCI State of the group is activated, the bit corresponding to the group of TCI State combinations is set to 1, which means that each TCI State in the group of TCI State combinations is activated, that is, the group of TCI State combinations is The two TCI states corresponding to the two TRPs are activated; if the bit corresponding to a certain group of TCI State combination is set to 0, it means that the group of TCI State combination is deactivated. At least one of the two TCI states corresponding to TRP is not activated.

具体地，如图2所示，可采用128×128个bit来全指示2个TRP所形成的128×128组TCI State组合中每组TCI State组合的激活/去激活状态，其中，T ₀、T ₁、T ₂……和T ₁₂₇可分别指示激活/去激活所述128×128组TCI State组合中第1组TCI State组合、第2组TCI State组合、第3组TCI State组合……和第128组TCI State组合。其中，需说明的是，图2仅示意所述128×128个bit中每个bit所分别指示的TCI State组合，并不表示所述第一指示字段的数据结构。 Specifically, as shown in Figure 2, 128×128 bits can be used to fully indicate the activation/deactivation status of each TCI State combination in the 128×128 TCI State combination formed by 2 TRPs, where T ₀ , T ₁ , T ₂ ... and T ₁₂₇ may respectively indicate activation/deactivation of the first group of TCI State combinations, the second group of TCI State combinations, and the third group of TCI State combinations in the 128×128 groups of TCI State combinations... and The 128th TCI State combination. It should be noted that, FIG. 2 only illustrates the TCI State combination indicated by each bit in the 128×128 bits, and does not indicate the data structure of the first indication field.

该方式中，所述第一指示字段可包括状态指示位，所述状态指示位与TCI state组集合中的TCI state组合/配对一一对应设置，用于指示对应的TCI state组合/配对的激活/去激活，所述TCI state组集合包括N个所述网络侧设备各自配置的TCI state可能形成的所有TCI state组合/配对，每一个TCI state组包括N个与N个所述TRP一一对应的TCI state。In this manner, the first indication field may include a state indicator bit, which is set in a one-to-one correspondence with the TCI state combination/pair in the TCI state group set, and is used to indicate the activation of the corresponding TCI state combination/pair /Deactivation, the TCI state group set includes all TCI state combinations/pairs that may be formed by the TCI states configured by each of the N network-side devices, and each TCI state group includes N one-to-one correspondence with the N TRPs The TCI state.

具体地，所述第一指示字段中可包括与所述TCI state组集合中的TCI state组合/配对数量一致的状态指示位，如使用128×128个状态指示位，来分别指示128×128组TCI state组合中每组的状态，其中，所述状态指示位可使用2个不同的bit来指示对应TCI state组合/配对的激活或去激活状态，如某TCI state组合的状态指示位置1指示该TCI state组合中包括的TCI state处于激活状态，状态指示位置0则指示该TCI state组合中包括的TCI state处于未激活状态。Specifically, the first indication field may include state indication bits that are consistent with the number of TCI state combinations/pairs in the TCI state group set. For example, 128×128 state indication bits are used to indicate 128×128 groups respectively The state of each group in the TCI state combination, where the state indicator bits can use 2 different bits to indicate the activation or deactivation state of the corresponding TCI state combination/pairing. For example, the state indicator position 1 of a certain TCI state combination indicates this The TCI state included in the TCI state combination is in an active state, and the state indicator position 0 indicates that the TCI state included in the TCI state combination is in an inactive state.

其二为：通过所述第一指示字段指示激活/去激活所述N个TRP的TCI State所形成的所有TCI State组合/配对中的部分组合/配对，具体可以是通过指示激活/去激活的TCI State组合/配对的序号(如ID号)来实现，其中，所述N个TRP的TCI State所形成的所有TCI State组合/配对均分配有各自的序号。具体地，可以通过多个比特对应的十进制数值指示激活的TCI State组合/配对的序号(如ID号)。The second is: the first indication field indicates the activation/deactivation of all TCI State combinations/pairs formed by the TCI State of the N TRPs, which can specifically be activated/deactivated by indicating activation/deactivation TCI State combination/pairing sequence numbers (such as ID numbers) are implemented, wherein all TCI State combinations/pairs formed by the TCI States of the N TRPs are assigned their own sequence numbers. Specifically, the sequence number (such as the ID number) of the activated TCI State combination/pair can be indicated by decimal values corresponding to multiple bits.

例如，以2个TRP进行协作传输为例，每个TRP配置有128个TCI State，2个TRP的TCI State可以形成128×128种TCI State组合，每一组TCI State 组合可以使用W(如W＝14)个bit来指示其激活/去激活状态，从而可以仅采用K×W个bit来指示激活/去激活所述128×128种TCI State组合中的K组TCI State组合；For example, taking two TRPs for cooperative transmission as an example, each TRP is configured with 128 TCI States, the TCI States of 2 TRPs can form 128×128 TCI State combinations, and each TCI State combination can use W (such as W =14) bits to indicate its activation/deactivation state, so that only K×W bits can be used to indicate activation/deactivation of K groups of TCI State combinations in the 128×128 TCI State combinations;

当2个TRP中每个TRP均需激活X个TCI State时，可取K＝X，其中，由于2个TRP的X个TCI State可形成X^X组TCI State组合，为了避免重复指示，可以在选取K组所需指示的TCI State组合时，保证每组TCI State组合中的2个TCI State均与其他组不同，进而实现通过K组TCI State组合来指示分别激活每个TRP的X个TCI State。When X TCI States need to be activated for each TRP in 2 TRPs, K=X can be taken, where X TCI States of 2 TRPs can form an X^X group TCI State combination. To avoid repeated instructions, you can When selecting the TCI State combination required by the K groups, ensure that the 2 TCI States in each TCI State combination are different from other groups, and then realize the activation of the X TCI States of each TRP through the K group TCI State combination .

具体地，如图3所示，由于MAC CE中最多可指示8组激活的TCI State组合，从而可以最多采用8×14个bit来指示激活所述128×128种TCI State组合中的8组TCI State组合，其中，T ₀～T ₁₃可指示激活所述128×128种TCI State组合中的一组TCI State组合，T ₁₄～T ₂₇可指示激活所述128×128种TCI State组合中的另一组TCI State组合，以此类推，最多可通过8×14个bit指示激活所述128×128种TCI State组合中的8组TCI State组合，其中，8组TCI State组合中每组TCI State组合所指示的2个TCI State均与其他组不同，14bit对应的数值可表示128×128组TCI State组合中某组的序号。其中，需说明的是，图3仅示意所述8×14个bit中每14个bit所分别指示的TCI State组合，并不表示所述第一指示字段的数据结构。 Specifically, as shown in Fig. 3, since the MAC CE can indicate up to 8 groups of activated TCI State combinations, 8×14 bits can be used at most to indicate the activation of 8 groups of TCI State combinations in the 128×128 TCI State combinations. State combinations, where T ₀ to T ₁₃ may indicate activation of one of the 128×128 TCI State combinations, and T ₁₄ to T ₂₇ may indicate activation of another of the 128×128 TCI State combinations A group of TCI State combinations, and so on, can activate 8 TCI State combinations among the 128×128 TCI State combinations through 8×14 bit instructions at most, where each of the 8 TCI State combinations is The two indicated TCI States are different from other groups, and the value corresponding to 14bit can represent the serial number of a certain group in the 128×128 TCI State combination. It should be noted that, FIG. 3 only illustrates the TCI State combination indicated by each 14 bits of the 8×14 bits, and does not indicate the data structure of the first indication field.

该方式中，所述第一指示字段可包括序号指示信息，所述序号指示信息用于指示激活/去激活的TCI state组合/配对在TCI state组集合中的序号，所述TCI state组集合包括N个所述网络侧设备各自配置的TCI state可能形成的所有TCI state组合/配对，每一个TCI state组合/配对包括N个与N个所述网络侧设备一一对应的TCI state。In this manner, the first indication field may include sequence number indication information, and the sequence number indication information is used to indicate the sequence number of the activated/deactivated TCI state combination/pair in the TCI state group set, and the TCI state group set includes All TCI state combinations/pairs that may be formed by the TCI states configured by each of the N network side devices, and each TCI state combination/pair includes N TCI states corresponding to the N network side devices one-to-one.

具体地，可以是通过对所述TCI state组合集中的每组TCI state组合/配对按序进行编号，使得每组TCI state组合/配对均具备各自的序号，从而在向终端发送MAC CE之前，可根据每个TRP处于激活/去激活状态的TCI state，确定对应的TCI state组合/配对，再确定所需指示的TCI state组合/配对在所述TCI state组合集中的序号，生成相应的序号指示字段，再向终端发送对应的MAC CE。Specifically, by sequentially numbering each group of TCI state combinations/pairs in the TCI state combination set, so that each group of TCI state combinations/pairs has its own sequence number, so that before sending the MAC CE to the terminal, Determine the corresponding TCI state combination/pair according to the TCI state of each TRP in the activated/deactivated state, and then determine the sequence number of the required TCI state combination/pair in the TCI state combination set, and generate the corresponding sequence number indication field , And then send the corresponding MAC CE to the terminal.

例如，接收到的MAC CE中的第一指示信息中包括序号000、010和101的序号指示字段，则可确定所述TCI state组合集中第0、2和5组TCI state组合处于激活状态。For example, if the received first indication information in the MAC CE includes sequence number indication fields of sequence numbers 000, 010, and 101, it can be determined that the 0th, 2nd, and 5th TCI state combinations in the TCI state combination set are in an active state.

或者，所述第一指示字段也可包括索引指示位，用于指示激活/去激活的TCI state组合/配对的索引。Alternatively, the first indication field may also include an index indication bit, which is used to indicate the index of the activated/deactivated TCI state combination/pair.

所述索引可以是激活/去激活的TCI state组合/配对的标识信息，具体地，可以是预先对每一组TCI state组合/配对设置了不同的索引标识，从而终端通过所述第一指示字段中的索引指示位，便可确定所指示的激活/去激活的TCI state组合/配对具体为哪一TCI state组合/配对。The index may be the identification information of the activated/deactivated TCI state combination/pairing. Specifically, a different index identifier may be set for each group of TCI state combination/pairing in advance, so that the terminal passes the first indication field The index indicator bit in the, you can determine which TCI state combination/pair the indicated activation/deactivation TCI state combination/pair is.

该实施方式中，对于上述采用N个指示位来分别指示一组TCI State组合/配对中的N个TCI State的激活或去激活状态的组合指示方式，可以理解为所述第一指示字段可包括与N个所述网络侧设备一一对应的N个指示位，每一个指示位用于指示对应网络侧设备配置的TCI State中的一个TCI State的激活/去激活状态。In this embodiment, for the above-mentioned combined indication mode that uses N indicator bits to respectively indicate the activation or deactivation state of the N TCI states in a group of TCI State combinations/pairs, it can be understood that the first indication field may include There are N indicator bits in one-to-one correspondence with the N network side devices, and each indicator bit is used to indicate the activation/deactivation state of one TCI State in the TCI State configured by the corresponding network side device.

也就是说，对于每一个TRP，可以分别使用1个指示位来指示该TRP配置的TCI State中某一个TCI State的激活/去激活状态，即所述第一指示信息可包括目标指示字段，所述目标指示字段中包括与参与多点协作传输的N个TRP一一对应的N个指示位。That is, for each TRP, one indicator bit can be used to indicate the activation/deactivation state of a certain TCI State in the TCI State configured by the TRP, that is, the first indicator information can include a target indicator field, so The target indication field includes N indication bits corresponding to the N TRPs participating in coordinated multi-point transmission one-to-one.

具体地，由于每个TRP均可以配置多个TCI State，且每个TRP又可以激活/去激活其中不同的TCI State，故所述目标指示字段可根据每个TRP所需指示的TCI State的数量的不同而具备不同的指示位数目。例如，每个TRP配置有128个TCI State，从而最少可采用N个指示位来一一指示所述N个TRP中每个TRP的一个TCI State的激活/去激活状态，最多可采用N×128^N个指示位来实现对所述N个TRP中每个TRP的128个TCI State的激活/去激活状态的全指示。Specifically, since each TRP can be configured with multiple TCI states, and each TRP can activate/deactivate different TCI states, the target indication field can be based on the number of TCI states that each TRP needs to indicate The number of indicator bits is different depending on the difference. For example, each TRP is configured with 128 TCI states, so at least N indicator bits can be used to indicate the activation/deactivation state of one TCI State of each TRP in the N TRPs, and a maximum of N×128 can be used. ^ N indicator bits to achieve full indication of the activation/deactivation state of the 128 TCI states of each TRP in the N TRPs.

这里也是描述有128×128的组合，而在第一种实施方式中，每个TCI State组合中的2个TCI State只能同时被激活，因而只适用于多点协作传输场景，而本实施方式中，每个TRP的TCI State均可以被单独激活，从而使得本实施方式还可适用于单个TRP传输的场景，例如，当2个TRP中其中1个TRP的与配置的128个TCI State对应的128个指示位均被置0时，表示该TRP当前未参与协作传输。这样，采用本实施方式，即可适用于多点协作传输，也可适用于单点传输。It is also described here that there are 128×128 combinations, and in the first embodiment, the two TCI States in each TCI State combination can only be activated at the same time, so it is only applicable to the multi-point coordinated transmission scenario, but this embodiment In each TRP, the TCI State of each TRP can be activated individually, so that this embodiment is also applicable to scenarios where a single TRP is transmitted. For example, when one TRP of 2 TRPs corresponds to the configured 128 TCI States When the 128 indicator bits are all set to 0, it means that the TRP is not currently participating in coordinated transmission. In this way, by adopting this embodiment, it can be applied to coordinated multi-point transmission as well as single-point transmission.

如图4所示，以2个TRP进行协作传输为例，每个TRP配置有128个TCI State，从而可使用与所述2个TRP一一对应的2个指示位对所述2个TRP配置的TCI State中的一个TCI State的激活/去激活进行指示，其中，T0、T1可分别指示TRP0的TCI State0、TRP1的TCI State0是否激活(如T0置1可指示TRP0的TCI State0被激活，T1置0可指示TRP1的TCI State0未激活)，T2、T3可分别指示TRP0的TCI State1、TRP1的TCI State0是否激活，T4、T5可分别指示TRP0的TCI State2、TRP1的TCI State0是否激活，以此类推，通过遍历TRP0和TRP1的所有TCI State ID的所有组合，可实现对TRP0和TRP1的所有TCI State的激活/去激活的全指示。其中，需说明的是，图4仅示意2×128^2个bit中每个bit所分别指示的TRP的TCI State，并不表示所述第一指示字段的数据结构。As shown in Figure 4, taking two TRPs for cooperative transmission as an example, each TRP is configured with 128 TCI states, so that two indicator bits corresponding to the two TRPs can be used to configure the two TRPs. To indicate the activation/deactivation of a TCI State in the TCI State, T0 and T1 can respectively indicate whether the TCI State0 of TRP0 and the TCI State0 of TRP1 are activated (for example, if T0 is set to 1, it can indicate that the TCI State0 of TRP0 is activated, and T1 Set to 0 to indicate that the TCI State0 of TRP1 is not activated), T2 and T3 can respectively indicate whether the TCI State1 of TRP0 and the TCI State0 of TRP1 are activated. T4 and T5 can respectively indicate whether the TCI State2 of TRP0 and the TCI State0 of TRP1 are activated. By analogy, by traversing all combinations of all TCI State IDs of TRP0 and TRP1, a full indication of the activation/deactivation of all TCI States of TRP0 and TRP1 can be realized. It should be noted that FIG. 4 only illustrates the TCI State of the TRP indicated by each of the 2×128^2 bits, and does not indicate the data structure of the first indication field.

该实施方式中，对于上述采用R×C个指示位来指示R组TCI State组合/配对的激活/去激活的TCI State ID或比特索引的组合指示方式，可以理解为所述第一指示字段包括至少一个第六指示字段，也即R个第六指示字段，所述R是大于或等于1的整数，每个第六指示字段指示网络侧设备的激活/去激活的TCI state ID或者指示网络侧设备的激活/去激活的TCI state在MAC CE中的比特索引，具体地，每个第六指示字段可指示W个网络侧设备的激活/去激活的TCI state ID或者指示W个网络侧设备的激活/去激活的TCI state在MAC CE中的比特索引，为保证每个第六指示字段可指示多个网络侧设备的TCI state状态，所述W可以是大于或等于2的整数。In this embodiment, for the above-mentioned combination indication method of using R×C indicator bits to indicate the activation/deactivation of the R group TCI State combination/pairing TCI State ID or bit index, it can be understood that the first indication field includes At least one sixth indication field, that is, R sixth indication fields, where R is an integer greater than or equal to 1, and each sixth indication field indicates the activation/deactivation TCI state ID of the network side device or indicates the network side The bit index of the activated/deactivated TCI state of the device in the MAC CE. Specifically, each sixth indication field can indicate the activated/deactivated TCI state ID of W network-side devices or the TCI state IDs of W network-side devices. The bit index of the activated/deactivated TCI state in the MAC CE. To ensure that each sixth indication field can indicate the TCI state states of multiple network side devices, the W may be an integer greater than or equal to 2.

即通过所述MAC CE可指示R组TCI State组合/配对的激活/去激活，对于每个第六指示字段，均可包括C个指示位，C个指示位可指示W个网络侧设备的激活/去激活的TCI state ID或W个网络侧设备的激活/去激活的TCI state在所述MAC CE中的比特索引，例如，对于每个TCI state ID，均使用8个指示位来指示，则对于2个网络侧设备，可使用2×8个bit来指示一组TCI State组合/配对中每个网络侧设备的激活/去激活的TCI state ID，共使用8×2×8 个bit来指示8组TCI State组合/配对的激活/去激活的TCI state ID。That is, the MAC CE can indicate the activation/deactivation of the R group TCI State combination/pairing. For each sixth indicator field, it can include C indicator bits, and the C indicator bits can indicate the activation of W network-side devices. /Deactivated TCI state ID or the bit index of the activated/deactivated TCI state of W network-side devices in the MAC CE. For example, for each TCI state ID, 8 indicator bits are used to indicate, then For 2 network-side devices, 2×8 bits can be used to indicate the activation/deactivation TCI state ID of each network-side device in a set of TCI State combinations/pairs. A total of 8×2×8 bits are used to indicate 8 groups of TCI State IDs for activation/deactivation of TCI State combinations/pairs.

在实际应用中，可以先确定每个网络侧设备的激活/去激活的TCI state ID，然后从每个网络侧设备中分别选取一个激活/去激活的TCI state ID进行组合/配对，每个组合/配对通过一个第六指示字段进行指示。In practical applications, you can first determine the activated/deactivated TCI state ID of each network side device, and then select an activated/deactivated TCI state ID from each network side device for combination/pairing. Each combination / Pairing is indicated by a sixth indication field.

其中，所述第六指示字段可包括：至少一个第七指示字段，如W个第七指示字段，每个第七指示字段指示一个网络侧设备的激活/去激活的TCI state ID或者指示一个网络侧设备的激活/去激活的TCI state在MAC CE中的比特索引，为保证每个第六指示字段可指示多个网络侧设备的TCI state状态，所述W可以是大于或等于2的整数。Wherein, the sixth indication field may include: at least one seventh indication field, such as W seventh indication fields, each seventh indication field indicates the activation/deactivation TCI state ID of a network side device or indicates a network The bit index of the activated/deactivated TCI state of the side device in the MAC CE. To ensure that each sixth indication field can indicate the TCI state of multiple network side devices, W may be an integer greater than or equal to 2.

第二种实施方式中，可以采用单独指示的方式来独立指示每个网络侧设备的TCI State的激活/去激活状态，即所述第一指示信息也可以是包括用于指示TCI State的激活/去激活的第二指示字段。In the second implementation manner, a separate indication method can be used to independently indicate the activation/deactivation status of the TCI State of each network side device, that is, the first indication information may also include the activation/deactivation status for indicating the TCI State. The second indication field of deactivation.

其中，所述MAC CE的数量为一个时，所述第二指示字段可以包括以下至少一种：Wherein, when the number of MAC CE is one, the second indication field may include at least one of the following:

至少一个第三指示字段，如M个第三指示字段，每一个第三指示字段对应于一个网络侧设备，字段中的每个比特用于指示网络侧设备的TCI state的激活/去激活；其中，为保证通过所述第二指示字段来实现对多个网络侧设备的TCI state状态的指示，所述M可为大于或等于2的整数；At least one third indication field, such as M third indication fields, each third indication field corresponds to a network side device, and each bit in the field is used to indicate the activation/deactivation of the TCI state of the network side device; where , In order to ensure that the indication of the TCI state of multiple network-side devices is achieved through the second indication field, the M may be an integer greater than or equal to 2;

至少一个第四指示字段，如K个第四指示字段，每个第四指示字段指示一个网络侧设备的激活的TCI state的TCI state ID；其中，为保证通过所述第二指示字段来实现对多个网络侧设备的TCI state状态的指示，所述K可为大于或等于2的整数；At least one fourth indication field, such as K fourth indication fields, each fourth indication field indicates the TCI state ID of the activated TCI state of a network side device; wherein, to ensure that the second indication field is used to achieve Indication of the TCI state state of multiple network side devices, the K may be an integer greater than or equal to 2;

所述MAC CE的数量为多个时，每个所述MAC CE携带的第一指示信息中的第二指示字段包括：When the number of MAC CEs is multiple, the second indication field in the first indication information carried by each MAC CE includes:

第五指示字段，所述第五指示字段对应于一个网络侧设备，字段中的每个比特用于指示对应网络侧设备的TCI state的激活/去激活。The fifth indication field, the fifth indication field corresponds to a network side device, and each bit in the field is used to indicate the activation/deactivation of the TCI state of the corresponding network side device.

该实施方式中，当所述MAC CE的数量为一个时，对于每一个TRP，可以分别采用一个第三指示字段来指示该TRP配置的所有TCI State的激活/去激活状态，所述第三指示字段的长度可等于TRP配置的TCI State的数目，如对于某个TRP，可以采用128个bit来一一指示该TRP配置的128个TCI State的激活/去激活状态。In this embodiment, when the number of MAC CEs is one, for each TRP, a third indication field may be used to indicate the activation/deactivation status of all TCI states configured by the TRP. The third indication The length of the field can be equal to the number of TCI states configured by the TRP. For example, for a certain TRP, 128 bits can be used to indicate the activation/deactivation states of the 128 TCI states configured by the TRP one by one.

如图5所示，以2个TRP进行协作传输为例，每个TRP配置有128个TCI State，从而可使用所述MAC CE中前128个bit来指示TRP0配置的所有TCI State的激活/去激活，使用所述MAC CE中后128个bit来指示TRP1配置的所有TCI State的激活/去激活，其中，某个bit置1，指示对应TCI State被激活，某个bit置0，指示对应TCI State未被激活；需说明的是，图5仅示意2×128个bit中前128个bit和后128个bit所分别指示的TRP的TCI State，并不表示所述第一指示字段的数据结构。As shown in Figure 5, taking two TRPs for cooperative transmission as an example, each TRP is configured with 128 TCI States, so that the first 128 bits in the MAC CE can be used to indicate the activation/deactivation of all TCI States configured by TRP0. Activate, use the last 128 bits of the MAC CE to indicate the activation/deactivation of all TCI states configured by TRP1, where a bit is set to 1, indicating that the corresponding TCI State is activated, and a bit is set to 0, indicating the corresponding TCI State is not activated; it should be noted that Figure 5 only shows the TCI State of TRP indicated by the first 128 bits and the last 128 bits of the 2×128 bits, and does not indicate the data structure of the first indication field .

或者对于每一个TRP，也可以分别采用一个第四指示字段来指示该TRP的处于激活状态的TCI State的ID号。需说明的是，为了实现对所述N个网络侧设备配置的TCI State的全指示，所述M和所述K均可以等于所述N。具体地，可通过第四指示字段对应的十进制数值指示激活的TCI State的TCI State ID。Or for each TRP, a fourth indication field may also be used to indicate the ID number of the TCI State in the active state of the TRP. It should be noted that, in order to achieve full indication of the TCI State configured for the N network-side devices, both the M and the K may be equal to the N. Specifically, the TCI State ID of the activated TCI State can be indicated by the decimal value corresponding to the fourth indication field.

具体地，由于每个TRP均可以配置多个TCI State，且每个TRP又可以激活/去激活其中不同的TCI State，故所述第四指示字段可根据对应TRP所需指示的激活的TCI State的数量的不同而具备不同的字段长度，例如，每个TRP配置有128个TCI State，对于每一个TRP，可使用7个bit来表示其配置的各TCI State的ID号，从而可仅采用n×7个bit来指示该TRP配置的128个TCI State中的n个处于激活状态的TCI State的TCI State ID。Specifically, since each TRP can be configured with multiple TCI States, and each TRP can activate/deactivate different TCI States among them, the fourth indication field can be based on the activated TCI State indicated by the corresponding TRP. For example, each TRP is configured with 128 TCI States. For each TRP, 7 bits can be used to represent the ID number of each TCI State configured, so that only n ×7 bits to indicate the TCI State IDs of n active TCI States among the 128 TCI States configured by the TRP.

例如，在每个TRP最多可激活8个TCI State的情况下，也可使用所述MAC CE中前一个字段(字段长度可为8×7个bit)来指示TRP0配置的所有TCI State中的处于激活状态的8个TCI State ID，使用所述MAC CE中后一个字段来指示TRP1配置的所有TCI State中处于激活状态的8个TCI State ID，从而只需使用8×14bit便可实现对2个TRP的处于激活状态的TCI State的指示。For example, when each TRP can activate up to 8 TCI States, the previous field in the MAC CE (the field length can be 8×7 bits) can also be used to indicate the status of all TCI States configured by TRP0. The eight TCI State IDs in the active state use the latter field in the MAC CE to indicate the eight TCI State IDs in the active state among all the TCI States configured by TRP1, so that only 8×14 bits can be used to achieve two Indication of the active TCI State of TRP.

当所述MAC CE的数量为多个时，对于每一个TRP，可以分别采用一个MAC CE来指示该TRP的TCI state的激活/去激活，具体地，可以是通过其携带的第一指示信息中的第二指示字段来指示，每个MAC CE中的第二指示字段均包括用于指示对应TRP的TCI state的激活/去激活的第五指示字段，每个第五指示字段的长度可与对应TRP所需指示的TCI State的数量相关，例如，第五指示字段的长度可等于对应TRP配置的TCI state的数目，或等于对应TRP的处于激活/去激活状态的TCI state的数目。When the number of MAC CEs is multiple, for each TRP, one MAC CE may be used to indicate the activation/deactivation of the TCI state of the TRP. Specifically, it may be in the first indication information carried by it. The second indication field of each MAC CE includes a fifth indication field for indicating the activation/deactivation of the TCI state of the corresponding TRP. The length of each fifth indication field can correspond to The number of TCI states required to be indicated by the TRP is related. For example, the length of the fifth indication field may be equal to the number of TCI states configured for the corresponding TRP, or equal to the number of TCI states in the activated/deactivated state corresponding to the TRP.

例如，以2个TRP进行协作传输为例，终端可以接收2个MAC CE，其中一个MAC CE携带用于指示TRP0的TCI State的激活/去激活的第一指示信息，该第一指示信息包括对应TRP0的第五指示字段，该第五指示字段中的每个比特用于指示TRP0的每个TCI State为激活还是去激活，另一个MAC CE携带则用于指示TRP1的TCI State的激活/去激活的第一指示信息，该第一指示信息包括对应TRP1的第五指示字段，该第五指示字段中的每个比特用于指示TRP1的每个TCI State为激活还是去激活。For example, taking two TRPs for cooperative transmission as an example, the terminal can receive two MAC CEs, one of which MAC CE carries first indication information for indicating activation/deactivation of the TCI State of TRP0, and the first indication information includes the corresponding The fifth indication field of TRP0, each bit in the fifth indication field is used to indicate whether each TCI State of TRP0 is activated or deactivated, and the other MAC CE carried is used to indicate the activation/deactivation of the TCI State of TRP1 The first indication information includes a fifth indication field corresponding to TRP1, and each bit in the fifth indication field is used to indicate whether each TCI State of TRP1 is activated or deactivated.

上述方式中，MAC CE可以通过N个比特指示至少1个网络侧设备的TCI state的激活/去激活,N是整数。其中一种方式中，N个比特中的每个比特指示一个TCI state ID的激活/去激活。而另一种方式，N个比特中至少包括一个长度为S的比特段，该长度为S的比特段用于指示激活的TCI state的TCI state ID。In the above manner, the MAC CE may indicate the activation/deactivation of the TCI state of at least one network-side device through N bits, where N is an integer. In one of the ways, each of the N bits indicates the activation/deactivation of a TCI state ID. In another manner, the N bits include at least one bit segment of length S, and the bit segment of length S is used to indicate the TCI state ID of the activated TCI state.

进一步地，MAC CE可以通过P个比特指示TCI state组合，P是整数。P个比特指示至少一个TCI state组合。作为一种方式，通过P个比特指示K个TCI state组合，那么通过P/K个比特指示一个TCI state组合。Further, the MAC CE can indicate the TCI state combination through P bits, where P is an integer. P bits indicate at least one TCI state combination. As a way, P bits are used to indicate K TCI state combinations, and then P/K bits are used to indicate a TCI state combination.

进一步地，P个比特中可以包括至少2个长度为P1的比特段，P1是整数。而长度为P1的比特段可以指示一个网络侧设备的激活TCI state ID，或者指示一个网络侧设备的激活TCI state ID在MAC CE中的比特索引。长度为P1的比特段也可以指示一个网络侧设备的激活TCI state在所有激活TCI state中的顺序位置。比如，一个网络侧设备激活了8个TCI state，P1可以通过3比特指示这8个激活的TCI state在MAC CE中的顺序位置，000代表第一个被激活的TCI state(假设MAC CE中比特顺序是从上至下，从右至左)，001代表第2个被激活的TCI state，以此类推，111代表第八个被激活的TCI state。Further, the P bits may include at least two bit segments with a length of P1, and P1 is an integer. The bit segment with a length of P1 can indicate the active TCI state ID of a network side device, or indicate the bit index of the active TCI state ID of a network side device in the MAC CE. The bit segment with a length of P1 may also indicate the sequential position of the activated TCI state of a network side device in all activated TCI states. For example, if a network-side device activates 8 TCI states, P1 can indicate the order position of these 8 activated TCI states in MAC CE with 3 bits, and 000 represents the first activated TCI state (assuming the bits in MAC CE The order is from top to bottom, from right to left), 001 represents the second activated TCI state, and so on, 111 represents the eighth activated TCI state.

参见图7，图7是本公开实施例提供的另一种指示方法的流程图。如图7所示，所述方法包括以下步骤：Refer to FIG. 7, which is a flowchart of another indication method provided by an embodiment of the present disclosure. As shown in Figure 7, the method includes the following steps:

步骤701、接收DCI，所述DCI中包括第二指示信息，所述第二指示信息用于指示N个网络侧设备的TCI State，所述N为大于或等于2的整数。Step 701: Receive DCI, where the DCI includes second indication information, where the second indication information is used to indicate the TCI State of N network-side devices, where N is an integer greater than or equal to 2.

本实施例中的指示方法可应用于终端，所述DCI指示的是终端对于相应网络侧设备使用的TCI State ID，所述第二指示信息指示的N个网络侧设备的TCI state，是进行数据接收或发送时应用的TCI state，即上述TCI state可以是终端接收数据使用的TCI state或网络侧发送数据使用的TCI state，比如PDSCH或PDCCH采用的TCI state；也可以是终端发送数据使用的TCI state或网络侧接收数据使用的TCI state，比如PUCCH/PUSCH/PRACH采用的TCI state。The indication method in this embodiment can be applied to the terminal. The DCI indicates the TCI State ID that the terminal uses for the corresponding network-side device, and the TCI state of the N network-side devices indicated by the second indication information is the data The TCI state applied when receiving or sending, that is, the above TCI state can be the TCI state used by the terminal to receive data or the TCI state used by the network to send data, such as the TCI state used by the PDSCH or PDCCH; it can also be the TCI used by the terminal to send data state or TCI state used by the network to receive data, such as the TCI state used by PUCCH/PUSCH/PRACH.

可选地，上述第二指示信息可以是DCI中的TCI c代码点ode point或TCI字段field。Optionally, the foregoing second indication information may be a TCI code point ode point or a TCI field field in the DCI.

上述接收DCI可以是接收网络侧设备发送的下行控制信息DCI，所述DCI中包括用于指示N个网络侧设备的TCI State的第二指示信息，其中，所述N个网络侧设备可以是参与多点协作传输的N个TRP，所述N为大于或等于2的整数。The above-mentioned receiving DCI may be receiving downlink control information DCI sent by a network-side device, and the DCI includes second indication information used to indicate the TCI State of N network-side devices, where the N network-side devices may be participating N TRPs for coordinated multipoint transmission, where N is an integer greater than or equal to 2.

具体地，所述N个TRP中的每个TRP均可以配置多个TCI State，且每个TRP配置的多个TCI State中有部分TCI State处于激活状态，另一部分处于去激活状态，终端在通过接收的MAC CE获知到每个TRP的处于激活/去激活状态的TCI State后，还需从所述处于激活状态的TCI State中选择实际采用的TCI State，故网络侧设备可通过向终端下发DCI，来指示终端所述N个TRP中各TRP所使用的TCI State，具体可以是通过所述第二指示信息分别指示每个TRP使用哪一个TCI State，或指示使用激活的TCI State组合/配对的哪一组TCI State组合/配对，从而终端可通过各TRP所使用的TCI State与所述N个TRP进行数据传输，保证获得较高的信噪比或吞吐量。Specifically, each of the N TRPs can be configured with multiple TCI States, and among the multiple TCI States configured by each TRP, some of the TCI States are in the active state, and the other part is in the deactivated state. After the received MAC CE learns the activated/deactivated TCI State of each TRP, it also needs to select the actually used TCI State from the activated TCI State, so the network side device can send it to the terminal DCI is used to indicate the TCI State used by each TRP in the N TRPs of the terminal. Specifically, the second indication information may be used to indicate which TCI State each TRP uses, or to use an activated TCI State combination/pair Which set of TCI State is combined/paired, so that the terminal can transmit data with the N TRPs through the TCI State used by each TRP, ensuring a higher signal-to-noise ratio or throughput.

在DCI指示时，当是通过多个MAC CE来指示N个网路侧设备的TCI state的激活/去激活时，第二指示信息可以指示每个MAC CE中的第几个TCI state为使用的TCI state，例如，第二指示信息使用01指示每个网络侧设备使用的TCI state都是对应的MAC CE中第一个被激活的TCI state对应的TCI state ID，第二指示信息使用10指示每个网络侧设备使用的TCI state都是对应MAC CE中第二个被激活的TCI state对应的TCI state ID，以此类推。In the DCI indication, when multiple MAC CEs are used to instruct the activation/deactivation of the TCI states of N network-side devices, the second indication information can indicate which TCI state in each MAC CE is used TCI state, for example, the second indication information uses 01 to indicate that the TCI state used by each network side device is the TCI state ID corresponding to the first activated TCI state in the corresponding MAC CE, and the second indication information uses 10 to indicate every The TCI state used by each network-side device corresponds to the TCI state ID corresponding to the second activated TCI state in the MAC CE, and so on.

MAC CE包括K个指示字段(K>＝2)，指示大于等于2个激活的TCI state的TCI state ID，其中第i个指示字段指示第m个TCI state的TCI state ID，第(i+1)个指示字段指示第(m+1)个TCI state的TCI state ID。MAC CE includes K indication fields (K>=2), indicating the TCI state ID of 2 or more active TCI states, where the i-th indication field indicates the TCI state ID of the m-th TCI state, and the (i+1)th ) Indicator fields indicate the TCI state ID of the (m+1)th TCI state.
