具体实施方式
TCI状态用于指示不同的信道和/或参考信号的波束。以物理下行共享信道(Physical Downlink Shared Channel，PDSCH)为例，采用RRC+MAC-CE，Media Access Control-Control Element+DCI的信令架构来指示TCI状态：RRC配置可用的TCI状态集合；MAC-CE从可用的TCI状态集合中激活一些TCI状态；通过DCI信令，从激活的TCI状态中指示一个TCI状态用于指示PDSCH解调参考信号(Demodulation Reference Signal，DMRS)的空间接收参数。
相关技术中，需要通过不同的指令来分别指示PUCCH、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理下行控制信道(Physical Downlink Control Channel，PDCCH)和PDSCH的波束或空间参数，但是，可能存在部分信道甚至所有信道采用的波束方向相同的情况。为了节省信令开销及降低指示时延，相关技术中引入了Unified TCI架构。在Unified TCI架构中，通过一个DCI信令或一个MAC-CE信令，可以更新下行信道和/或上行信道的波束。具体地，对应于不同的TCI状态：
联合(joint)TCI：上下行信道的波束方向相同，一个信令同时更新上 行信道及下行信道的波束；
独立(separate)TCI：上行信道(PUSCH、PUCCH)的波束方向相同，下行信道(PDSCH、PDCCH)的波束方向相同，但上行信道和下行信道的波束方向不同。一个信令可以更新：1、PDCCH和PDSCH的波束；2、PUSCH和PUCCH的波束；3、PDCCH、PDSCH、PUCCH和PUSCH的波束。
实际应用时，采用joint TCI还是separate TCI，是由RRC来配置的。Unified TCI架构也采用了RRC+MAC-CE+DCI的信令架构，当RRC配置了多个joint TCI或separate DL/UL TCI状态，而MAC-CE信令仅激活了一个TCI状态时，激活的TCI状态即为选择的TCI；当MAC-CE信令激活了多个TCI状态时，通过DCI格式1_1(format1_1)或DCI格式1_2(format 1_2)从激活的TCI状态中选择TCI状态。
目前，Unified TCI架构只适用于单收发节点的场景，在multi-TRP场景下无法实现波束指示。
其中，multi-TRP场景的波束指示情况相比于单TRP更为复杂，具体地，包括以下情况：
情况一：TRP0、TRP1均为joint TCI工作模式，终端根据指示的信息得到TRP0的TCI或TRP1的TCI或TRP0+TRP1的TCI，需指示出1个或2个TCI状态；
情况2：TRP0、TRP1均为separate TCI工作模式，该工作模式包括以下几种指示情况：
1、DCI指示一个TRP的TCI状态，指示的TCI状态可以是UL TCI或DL TCI或UL+DL TCI。
2、DCI指示两个TRP的TCI状态，指示的TCI状态可以是UL TCI或DL TCI或UL+DL TCI。
情况2中，需指示出1个或2个或3个或4个TCI状态。
情况3：一个TRP为joint TCI工作模式，另一个TRP为separate TCI工 作模式，这里，假设TRP 0为joint TCI工作模式，TRP1为separate TCI工作模式，包括以下几种指示情况：
1、DCI指示TRP0的TCI。
2、DCI指示TRP1的UL TCI或DL TCI或UL+DL TCI。
3、DCI指示TRP0的TCI+TRP 1的UL TCI或DL TCI或UL+DL TCI。
情况3中，需指示出1个或2个或3个TCI状态。
基于上述列举的三种情况，将Unified TCI架构扩展到multi-TRP场景后，首先需要解决如何指示不同情况不同组合的波束信息的问题。
基于此，本公开的各实施例中，第一终端接收第一基站发送的第一DCI，其中，所述第一DCI用于指示至少一个TCI状态组中的第一TCI状态组；所述至少一个TCI状态组由第一MAC-CE信令基于RRC配置的TCI状态激活；每个TCI状态组用于指示至少一个TCI状态。上述方案能够基于Unified TCI架构实现对多种组合的波束信息进行指示，这样，Unified TCI架构不再仅适用于单收发节点的场景，在multi-TRP场景下也能够准确地实现对不同收发节点的波束指示。
下面结合附图及实施例对本公开再作进一步详细的描述。
本公开实施例提供了一种TCI的指示方法，应用于第一终端，如图1所示，该方法包括：
步骤101：接收第一DCI。
其中，所述第一DCI用于指示至少一个TCI状态组中的第一TCI状态组；所述至少一个TCI状态组由第一MAC-CE信令基于RRC配置的TCI状态激活；每个TCI状态组用于指示至少一个TCI状态。
这里，为了解决如何指示不同情况不同组合的波束信息的问题，沿用了RRC+MAC-CE+DCI的信令架构，RRC配置多个TCI状态，包括joint TCI和/或separate TCI，MAC-CE信令基于RRC配置的TCI状态激活一个或多个TCI状态组，每个TCI状态组中包括了一个或多个TCI状态。基站向终端下 发DCI，DCI用于指示的是TCI状态组，由于TCI状态组可以携带多个TCI状态，因此，可以通过DCI向终端指示TCI状态组，实现对多种组合的波束信息的指示。
实际应用时，为了至少指示上述三种不同情况，在一实施例中，每个TCI状态组用于指示1个或2个或3个或4个TCI状态。也就是说，根据上文列举的不同情况对TCI状态的数量需求，1个TCI域的码点(codepoint)可以指示1个或2个或3个或4个TCI状态。每个码点指示的TCI状态与MAC-CE信令激活的TCI状态组有关。在一实施例中，所述第一MAC-CE信令激活的每个TCI状态组至少包括以下信息之一：
TCI状态组包括的TCI状态的个数，或者TCI状态组中的第一个TCI状态；
TCI状态组包括的TCI状态的索引；
指示TCI状态的组标识；
指示TCI状态为DL TCI状态或UL TCI状态。
其中，指示TCI状态的组标识，用于标识收发节点(Transmission and Receiving Points，TRP)。例如，以多收发节点场景为例，组标识“0”用于标识TRP 0，对应的TCI状态与TRP 0关联，组标识“1”用于标识TRP 1，对应的TCI状态与TRP 1关联。或者，组标识用于标识CORESET和/或PUCCH，表征CORESET和/或PUCCH的组标识。
此外，将Unified TCI架构扩展到multi-TRP场景后，还需要解决终端收到波束指示信息后如何更新波束的问题。为了解决该问题，本例中将CORESET与PUCCH分组，当DCI指示某一个TCI状态组时，根据TCI状态组中的TCI状态所对应的组标识，确定哪些CORESET和/或PUCCH的TCI状态需要更新。基于此，在一实施例中，所述方法还包括：
在所述第一DCI指示的所述第一TCI状态组生效后，根据所述第一TCI状态组中包括的信息确定需要更新的CORESET和/或PUCCH。
具体地，所述根据所述第一TCI状态组中包括的信息确定需要更新的CORESET和/或PUCCH，包括：
将第一组标识的CORESET和/或PUCCH的TCI状态更新为对应组标识的TCI状态。
也就是，基于第一TCI状态组中的TCI状态关联的组标识，找到CORESET和/或PUCCH，并将找到的CORESET和/或PUCCH确定为需要更新TCI状态的CORESET和/或PUCCH，进行TCI状态的更新。
进一步地，在所述第一TCI状态组中包括DL TCI状态的情况下，将所述第一组标识的CORESET的TCI状态更新为对应的DL TCI状态；
在所述第一TCI状态组中包括UL TCI状态的情况下，将所述第一组标识的PUCCH的空间关系更新为对应的UL TCI状态。
也就是说，针对joint TCI的情况，在DCI的指示生效后，确定指示的TCI状态组中的TCI状态所关联的组标识对应的CORESET和PUCCH，将确定出的CORESET和PUCCH的TCI状态更新为指示的TCI状态组中对应的TCI状态；
针对separate TCI的情况，在DCI的指示生效后，当指示的TCI状态组包括DL TCI状态时，将与DL TCI状态所关联的组标识对应的CORESET的TCI状态更新为该DL TCI状态；当指示的TCI状态组包括UL TCI状态时，在指示生效后，将与UL TCI状态所关联的组标识对应的PUCCH的TCI状态更新为该UL TCI状态。
对应地，本公开实施例提供了还一种TCI的指示方法，应用于第一基站，如图2所示，该方法包括：
步骤201：向第一终端发送第一DCI。
其中，所述第一DCI用于指示至少一个TCI状态组中的第一TCI状态组；所述至少一个TCI状态组由第一MAC-CE信令基于RRC配置的TCI状态激活；每个TCI状态组用于指示至少一个TCI状态。
这里，为了解决如何指示不同情况不同组合的波束信息的问题，沿用了RRC+MAC-CE+DCI的信令架构，RRC配置多个TCI状态，包括joint TCI和/或separate TCI，MAC-CE信令基于RRC配置的TCI状态激活一个或多个TCI状态组，每个TCI状态组中包括了一个或多个TCI状态。基站向终端下发DCI，DCI用于指示的是TCI状态组，由于TCI状态组可以携带多个TCI状态，因此，可以通过DCI向终端指示TCI状态组，实现对多种组合的波束信息的指示。
实际应用时，为了至少指示上述三种不同情况，在一实施例中，每个TCI状态组用于指示1个或2个或3个或4个TCI状态。也就是说，根据上文列举的不同情况对TCI状态的数量需求，1个TCI域的码点可以指示1个或2个或3个或4个TCI状态。每个码点指示的TCI状态与MAC-CE信令激活的TCI状态组有关。在一实施例中，所述第一MAC-CE信令激活的每个TCI状态组至少包括以下信息之一：
TCI状态组包括的TCI状态的个数，或者TCI状态组中的第一个TCI状态；
TCI状态组包括的TCI状态的索引；
指示TCI状态的组标识；
指示TCI状态为DL TCI状态或UL TCI状态。
其中，指示TCI状态的组标识，用于标识TRP。例如，以多收发节点场景为例，组标识“0”用于标识TRP 0，对应的TCI状态与TRP 0关联，组标识“1”用于标识TRP 1，对应的TCI状态与TRP 1关联。或者，组标识用于标识CORESET和/或PUCCH，表征CORESET和/或PUCCH的组标识。
本公开实施提供的TCI的指示方法，第一终端接收第一基站发送的第一DCI，其中，所述第一DCI用于指示至少一个TCI状态组中的第一TCI状态组；所述至少一个TCI状态组由第一MAC-CE信令基于RRC配置的TCI状态激活；每个TCI状态组用于指示至少一个TCI状态。上述方案能够基于 Unified TCI架构实现对多种组合的波束信息进行指示，这样，Unified TCI架构不再仅适用于单收发节点的场景，在多收发节点场景下也能够准确地实现对不同收发节点的波束指示。
下面结合应用实施例对本公开再作进一步详细的描述。
本应用实施例结合了多收发节点的场景，其中，TRP0和TRP1均为joint TCI工作模式，RRC配置1个TCI状态列表，包括有16个joint TCI状态，MAC-CE信令激活其中的部分TCI，如图3所示，形成8个TCI状态组。需要说明的是，图3中，BWP为Bandwidth Part的简称，即为带宽部分。
参照图3，第一列的字段用于标识对应的TCI状态是否为所处TCI状态组的第一个TCI状态，为“0”时表示该TCI状态为所处TCI状态组的第一个TCI状态。第二列的字段用于标识TCI状态所关联的组标识，第三列字段用于标识TCI状态的标识(Identifier，ID)。
实际应用时，当DCI的TCI域(field)为100时，指示MAC-CE信仅中的第4个TCI状态组。如图3中示出的，第4个TCI状态组包含2个TCI状态：TCI状态1000和TCI状态1010，其中TCI状态1000与组标识“0”关联，TCI状态与组标识“1”关联。
当DCI指示生效后，终端假设：接收到的与组“0”相关的CORESET的PDCCH的DMRS，与ID为1000的TCI状态的参考信号有空间准共址关系，与组“0”相关的PUCCH的空间发送参数由ID为1000的TCI状态确定。同理，UE假设：接收到的与组“1”相关的CORESET的PDCCH的DMRS，与ID为1010的TCI状态的参考信号有空间准共址关系，与组“1”相关的PUCCH的空间发送参数由ID为1010的TCI状态确定。
为了实现本公开实施例第一终端侧的方法，本公开实施例还提供了一种TCI的指示装置，设置在第一终端上，如图4所示，该装置包括：
