图1示出的是本公开一个示例性实施例提供的网络架构的框图，如图1所示，该准共址QCL指示系统可以包括：终端设备11和网络设备12。
终端设备11可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile  Station，MS)，物联网设备(Internet of Things，IoT)，工业物联网设备(Industry Internet of Things，IIoT)等等。为方便描述，上面提到的设备统称为终端设备。终端设备11与网络设备12之间通过某种空口技术互相通信，例如Uu接口。
网络设备12可以是基站，基站是一种部署在接入网中用以为终端设备11提供无线通信功能的装置。该基站既可以是终端设备11的服务小区的基站，也可以是终端设备11的服务小区相邻小区的基站。基站可以包括各种形式的宏基站，微基站，中继站，接入点、发送接收点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在5G NR系统中，称为gNodeB或者gNB。一个基站可以包含至少一个TRP。随着通信技术的演进，“基站”这一名称可能会变化。在本公开实施例中，所述的“网络设备”除特别说明之外，是指接入网设备，如基站。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于LTE(Long Term Evolution，长期演进)系统，也可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统，还可以适用于诸如NB-IoT(Narrow Band Internet of Things，窄带物联网)系统等其他通信系统，本申请对此不作限定。
在Rel-16中，PDCCH(Physical Downlink Control Channel，物理下行控制信道)、PDSCH(Physical Downlink Shared Channel，物理下行共享信道)、PUSCH(Physical Uplink Shared Channel，物理上行共享信道)、PUCCH(Physical Uplink Control Channel，物理上行控制信道)和/或参考信号等的TCI状态或spatialrelationinfo(空间关系信息)都是独立指示的，而且PDCCH和PUCCH使用MAC CE(Media Access Control Control Element，媒体接入层控制单元)来分别激活一个TCI状态或spatialrelationinfo。而PDSCH和PUSCH是通过DCI(Downlink Control Information，下行控制信令)来指示其各自对应的TCI状态或spatialrelationinfo。其中，参考信号包括DMRS(DeModulation Reference signal，解调参考信号)，CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)，SRS(Sounding Reference Signal，探测参考信号)，PRS(Positioning Reference Signal，定位参考信号)，TRS(Tracking Reference Signal，追踪参考信号)等。CSI-RS包括用于信道状态信息测量的CSI-RS或用于波束管理(Beam Management)的CSI-RS或用于pathloss(路径损失)估计的CSI-RS；SRS包括用于基于codebook(码本)/non-codebook(非码本)的信道状态信息测量的SRS，或者，SRS包括用于波束管理/定位的SRS。目前为了减少信令开销，希望使用unified TCI state(统一的TCI状态)。unified TCI state目前包括joint TCI state(联合传输配置指示)、separate DL TCI state(separate DownLink Transmission Configuration Indication，下行专用传输配置指示)和separate UL TCI state(separate UpLink Transmission Configuration Indication，上行专用传输配置指示)。joint TCI state可以指示下行传输和上行传输共用的QCL参数；separate DL TCI state用于指示下行传输专用的QCL参数，separate UL TCI state用于指示上行传输专用的QCL参数。
若网络设备指示一个用于下行传输的separate DL TCI state，那么该TCI状态可以用于终端的PDSCH和一部分PDCCH(比如UE dedicated PDCCH(User Equipment dedicated PDCCH，用户终端专用的PDCCH))，以及一些下行参考信号。若网络设备指示一个用于上行传输的separate UL TCI state，那么该TCI状态可以用于终端的PUSCH和PUCCH，以及一些上行参考信号。若网络设备指示一个joint TCI state，那么该TCI状态可以用于终端的PDSCH和一部分PDCCH(比如UE dedicated PDCCH)以及一些下行参考信号；和/或，用于终端的PUSCH和PUCCH以及一些上行参考信号。
目前，仅能实现对一个TRP的TCI状态的指示，TCI状态的指示条件较为局限，不够灵活。
图2是根据一示例性实施例示出的一种准共址QCL指示方法的流程图，本实施例以该准 共址QCL指示方法应用于图1所示网络架构中来举例说明。该方法可以包括如下步骤201：
在步骤201中，终端设备接收第一信息，第一信息用于指示至少一个第一TCI状态和/或至少一组第二TCI状态。
可选地，终端设备接收来自于网络设备的第一信息。也即，网络设备向终端设备发送第一信息，终端设备接收网络设备发送的第一信息。
其中，每个第一TCI状态用于指示下行传输和上行传输共用的QCL参数，每组第二TCI状态用于指示下行传输专用的QCL参数和上行传输专用的QCL参数中的至少一项。某天线端口(也称为参考信号端口port)的信道特性可以从另一个天线端口推导出，则认为这两个端口QCL，从一个天线端口获得的信道估计结果，可以用于另一个端口。
可选地QCL参数也称为QCL假设(QCL assumption)或QCL信息。TCI状态包含QCL参数，QCL参数包括QCL Type A、QCL Type B、QCL Type C、QCL Type D中的至少一项。其中QCL Type A、QCL TypeB和QCL Type C包括多普勒偏移、多普勒扩展、平均时延和时延扩展中的至少一项。QCL Type D对应空间接收参数信息。QCL Type D也可以俗称为beam信息，即波束信息。
在一些实施例中，TCI状态用于告知终端设备接收PDCCH/PDSCH的DMRS和/或PDCCH/PDSCH时，使用接收网络设备发送的哪个SSB或CSI-RS对应的QCL参数；或告知终端设备发送PUCCH/PUSCH时，使用哪个参考信号(比如SRS或CSI-RS)对应的QCL参数或spatialrelationinfo(空间关系信息)或spatial setting(空间环境)。
在示例性实施例中，第一TCI状态为joint TCI state(联合TCI状态)，可以指示下行传输和上行传输共用的QCL参数。
可选地，下行传输包括PDSCH、PDCCH、下行参考信号中至少一项的传输；上行传输包括PUSCH、PUCCH、上行参考信号中至少一项的传输。
在一些实施例中，参考信号资源以资源标识或资源集标识来指示。
在示例性实施例中，每组第二TCI状态包括separate DL TCI state和/或separate UL TCI state。也即，对于某一组第二TCI状态来说，可以仅包括separate DL TCI state，也可以仅包括separate UL TCI state，还可以包括separate DL TCI state和separate UL TCI state。
可选地，每组第二TCI状态包括一个或两个第二TCI状态，每个第二TCI状态用于指示下行传输专用的QCL参数或上行传输专用的QCL参数。
在一些实施例中，某一组第二TCI状态可以仅用于指示下行传输专用的QCL参数，而不指示上行传输专用的QCL参数；某一组第二TCI状态也可以仅用于指示上行传输专用的QCL参数，而不指示下行传输专用的QCL参数；某一组第二TCI状态还可以既指示下行传输专用的QCL参数，又指示上行传输专用的QCL参数。
可选地，对于多个TRP，至少存在以下三种情况：
(1)通过多个第一TCI状态指示多个TRP分别对应的QCL参数；
(2)通过多组第二TCI状态指示多个TRP分别对应的QCL参数；
(3)通过至少一个第一TCI状态和至少一组第二TCI状态指示多个TRP分别对应的QCL参数。
在一些实施例中，以n个TRP为例，n为大于1的整数，那么：
对应于上述情况(1)，n个TRP可以对应有n个第一TCI状态，每个TRP的QCL参数(波束)采用一个第一TCI状态来指示；
对应于上述情况(2)，n个TRP可以对应有n组第二TCI状态，每个TRP的QCL参数(波束)采用一组第二TCI状态来指示；
对应于上述情况(3)，n个TRP可以对应有n 1个第一TCI状态和n 2组第二TCI状态，n 1+n 2等于n，n 1和n 2均为正整数；每个TRP的QCL参数(波束)采用一个第一TCI状态或一组第二TCI状态来指示。
可选地，第一信息包括第一MAC CE，第一MAC CE激活一个码点对应的至少一个第一 TCI状态和/或至少一组第二TCI状态。
在一些实施例中，第一信息仅通过MAC CE激活一个码点以指示一个或多个TRP的TCI状态。当需要变更TCI状态(即变更TCI状态指示的QCL参数)时，终端设备接收新的MAC CE以激活一个码点对应的变更后的TCI状态(当然，变更后的TCI状态包括至少一个第一TCI状态和至少一组第二TCI状态中的至少一项)。可选地，码点也称为codepoint。
在示例性实施例中，以Multi-TRP场景包括两个TRP为例，第一MAC CE指示两个TRP(包括第一TRP和第二TRP)分别对应的TCI状态，则至少存在以下几种可能的情况：
(1)第一MAC CE仅指示第一TRP对应的第一TCI状态，第一MAC CE未指示第二TRP对应的TCI状态；
(2)第一MAC CE指示第一TRP对应的第一TCI状态和第二TRP对应的第一TCI状态；
(3)第一MAC CE指示第一TRP对应的第一TCI状态和第二TRP对应的第二TCI状态；
(4)第一MAC CE仅指示第一TRP对应的第二TCI状态，第一MAC CE未指示第二TRP对应的TCI状态；
(5)第一MAC CE指示第一TRP对应的第二TCI状态和第二TRP对应的第一TCI状态；
(6)第一MAC CE指示第一TRP对应的第二TCI状态和第二TRP对应的第二TCI状态；
(7)第一MAC CE指示第二TRP对应的第一TCI状态，第一MAC CE未指示第一TRP对应的TCI状态；
(8)第一MAC CE指示第二TRP对应的第二TCI状态，第一MAC CE未指示第一TRP对应的TCI状态。
需要注意的是，上述TRP对应的第二TCI状态，可以是指一个或两个第二TCI状态；也即，第二TCI状态是指separate DL TCI state和/或separate UL TCI state。
可选地，第一信息包括第二MAC CE和DCI(Downlink Control Information，下行控制信息)，第二MAC CE激活多个码点分别对应的至少一个第一TCI状态和/或至少一组第二TCI状态，DCI指示上述多个码点中的一个码点。
在一些实施例中，第二MAC CE激活了多个码点，多个码点中的每个码点都至少对应于一个TRP的TCI状态。多个码点中的每一个码点，都可以指示多个TRP的TCI状态。可选地，通过DCI进一步指示各个时段或当前时段或下个时段，采用多个码点中的哪一个码点来指示一个或多个TRP的TCI状态。
本公开实施例中，通过采用MAC CE激活多个码点以对一个或多个TRP的TCI状态进行指示，通过相应的DCI指示信息确定每次所采用的码点，从而无需多次采用MAC CE更换码点对应的TCI状态，减少TCI状态更新的时延。
综上所述，本公开通过第一信息指示第一TCI状态和/或至少一组第二TCI状态，从而可以实现对多个TRP的TCI状态进行指示，从而提升TCI状态指示的灵活性。
另外，由于本公开可以实现对多个TRP的TCI状态进行指示，还提高了针对多个TRP的传输性能。
在示例性实施例中，如图3所示，准共址QCL指示方法还包括如下步骤202：
在步骤202中，终端设备接收第二信息，第二信息用于指示第一信息中包含的TCI状态的类型。
可选地，终端设备接收来自于网络设备的第二信息。也即，网络设备向终端设备发送第二信息，终端设备接收网络设备发送的第二信息。
其中，TCI状态的类型包括第一TCI状态和第二TCI状态。
在一些实施例中，第一信息和第二信息是先后分别发送至终端设备的，第一信息和第二信息也可以是包含在同一个信令中、被同时发送至终端设备的。也即，可以先执行步骤201、再执行步骤202，步骤201和步骤202也可以同时执行。
可选地，第二信息用于指示第一信息中包含的TCI状态的类型包括第一TCI状态；或者，第二信息用于指示第一信息中包含的TCI状态的类型包括第二TCI状态；或者，第二信息用于指示第一信息中包含的TCI状态的类型包括第一TCI状态和第二TCI状态。
可选地，第一信息中包含的TCI状态的类型是独立指示的，或者，第一信息中包含的TCI状态的类型是同时指示的。
在示例性实施例中，在第二信息用于指示第一信息中包含的TCI状态的类型包括第一TCI状态的情况下，或者在第二信息用于指示第一信息中包含的TCI状态的类型包括第二TCI状态的情况下，第二信息可以分别独立指示多个TRP对应的TCI状态，也可以同时指示多个TRP对应的TCI状态。
例如，独立指示可以是：第一TRP对应于第一TCI状态、第二TRP对应于第一TCI状态、第三TRP对应于第一TCI状态等等；又例如，独立指示可以是：第一TRP对应于第二TCI状态、第二TRP对应于第二TCI状态、第三TRP对应于第二TCI状态等等；再例如，同时指示可以是：多个TRP均对应于第一TCI状态；还例如，同时指示可以是：多个TRP均对应于第二TCI状态。
本公开实施例中，在第二信息用于指示第一信息中包含的TCI状态的类型包括第一TCI状态的情况下，或者在第二信息用于指示第一信息中包含的TCI状态的类型包括第二TCI状态的情况下，第二信息可以同时指示多个TRP对应的TCI状态，从而进一步节省信令开销。
需要注意的是，在第二信息用于指示第一信息中包含的TCI状态的类型包括第一TCI状态和第二TCI状态的情况下，第一信息中包含的TCI状态的类型只能独立指示，不能同时指示。
例如，在两个TRP的情况下，某个码点可以指示第一TRP对应于第一TCI状态、第二TRP对应于第二TCI状态；或者，多个码点中的某个码点可以指示第一TRP对应于第二TCI状态、第二TRP对应于第一TCI状态；或者，多个码点中的码点1可以指示第一TRP对应于第一TCI状态、多个码点中的码点2可以指示第二TRP对应于第二TCI状态；或者，多个码点中的码点3可以指示第一TRP对应于第二TCI状态、多个码点中的码点4可以指示第二TRP对应于第一TCI状态。
本公开实施例对于Multi-TRP场景中对TCI状态的类型的指示，提供了以下几种方案(方案一至方案三)：
方案一：第二信息为RRC(Radio Resource Control，无线资源控制)信令
在一些实施例中，第二信息为不同于第一信息的RRC信令，即通过RRC信令指示第一信息中包含的TCI状态的类型。
以两个TRP为例，若RRC信令指示第一信息中包含的两个TRP的类型都是第一TCI状态，那么第一信息中每个码点针对每个TRP最多激活一个第一TCI状态；若RRC信令指示第一信息中包含的两个TRP的类型都是第二TCI状态，那么第一信息中每个码点针对每个TRP最多激活一组第二TCI状态，一组第二TCI状态包含一个separate DL TCI state和/或一个separate UL TCI state；若RRC信令指示第一信息中包含的第一TRP的类型为第一TCI状态、第二TRP的类型为第二TCI状态，那么第一信息中每个码点针对第一TRP最多激活一个第一TCI状态，针对第二TRP最多激活一组第二TCI状态，一组第二TCI状态包含一个separate DL TCI state和/或一个separate UL TCI state。
方案二：第二信息为MAC CE
在一些实施例中，每个TRP最多对应于两个TCI状态(即一对第二TCI状态)；则，如 下表1所示，对于两个TRP，每个码点最多对应有4个TCI状态。
表1
Figure PCTCN2022076956-appb-000001
如上表1，针对至少一个TCI状态，设置对应的指示信息(如C1、C2、C3和C4至少一项)用于表示对应的TCI状态是否出现。在示例性实施例中，以码点codepoint#0为例，TCI0,1和TCI 0,2对应于同一个TRP。TCI 0,1至少存在以下两种含义：
(1)TCI 0,1为第一TCI状态，同时用于上行传输和下行传输，这种情况下，TCI 0,2不会出现；
(2)TCI 0,1为第二TCI状态中的separate DL TCI state，这种情况下，TCI 0,2只要出现，一定是指第二TCI状态中的separate UL TCI state。但TCI 0,2也可以不出现，即仅有TCI 0,1指示某个TRP的separate DL TCI state。由于存在以上两种含义，这种情况下，若TCI 0,2不出现，终端设备就不会知道TCI 0,1是第一TCI状态还是第二TCI状态中的separate DL TCI state；为了进一步区分，可以对TCI 0,1进一步设置1bit(比特字符)类型指示符，用于区分这两种情况(即区分TCI 0,1是第一TCI状态还是第二TCI状态中的separate DL TCI state)。当然，也可以TCI 0,2出现，TCI 0,1不出现，具体解释可参见上文。因此某一码点对应的TCI0,1和TCI0,2存在以下至少一种组合：
组合1：TCI0,1对应的指示信息指示其不出现，TCI0,2对应的指示信息指示其不出现，TCI0,1的类型指示符指示0或1(由于TCI0,1和TCI0，2都不出现，那TCI0,1的类型指示符也没有意义)，则TCI0,1不出现、TCI0,2不出现；
组合2：TCI0,1对应的指示信息指示其出现，TCI0,2对应的指示信息指示其不出现，TCI0,1的类型指示符指示其为第一TCI状态，则TCI0,1出现、TCI0,2不出现；
组合3：TCI0,1对应的指示信息指示其出现，TCI0,2对应的指示信息指示其不出现，TCI0,1的类型指示符指示其为第二TCI状态，则TCI0,1出现、TCI0,2不出现；
组合4：TCI0,1对应的指示信息指示其出现，TCI0,2对应的指示信息指示其出现，TCI0,1的类型指示符指示其为第二TCI状态，则TCI0,1出现、TCI0,2出现；
组合5：TCI0,1对应的指示信息指示其不出现，TCI0,2对应的指示信息指示其出现，TCI0,1的类型指示符指示其为第二TCI状态，则TCI0,1不出现、TCI0,2出现。
如上表1，码点codepoint#0的TCI 0,3和TCI 0,4对应于两个TRP中的另一个TRP，对TCI 0,3和TCI 0,4的含义的介绍可参见上文中的TCI0,1和TCI0,2。
可选地，第二信息和第一信息共用同一个MAC CE(如第一MAC CE或第二MAC CE)，或者，第二信息和第一信息使用不同的MAC CE。
可选地，以下是第二信息和第一信息使用不同的MAC CE的例子。
示例性地，第二信息使用一个MAC CE指示了一个TRP的TCI状态类型为第一TCI状态，第一信息对应的另一个MAC CE针对该TRP每个码点只需要最多激活一个第一TCI状态。进一步地，第一信息针对该TRP每个码点还包含一个指示该第一TCI状态是否出现的指示信息。
示例性地，第二信息使用一个MAC CE指示了一个TRP的TCI状态类型为第二TCI状态，第一信息对应的另一个MAC CE针对该TRP每个码点需要最多激活两个第二TCI状态。 进一步地，第一信息针对该TRP每个码点还包含两个分别指示两个第二TCI状态是否出现的指示信息。
可选地，在第二信息和第一信息共用同一个MAC CE的情况下，每个码点包含第一信息域和第二信息域，第一信息域用于承载第一信息，第二信息域用于承载第二信息。
示例性的，一个MAC CE的每个码点针对一个TRP可能包含以下组合之一的指示域，其中类型指示符为第二信息域，其它为第一信息域。
组合1：TCI0,1对应的指示信息指示其不出现，TCI0,2对应的指示信息指示其不出现，类型指示符指示0或1(由于TCI0,1和TCI0，2都不出现，那类型指示符也没有意义)，则TCI0,1不出现、TCI0,2不出现；
组合2：TCI0,1对应的指示信息指示其出现，TCI0,2对应的指示信息指示其不出现，类型指示符指示其为第一TCI状态，则TCI0,1出现、TCI0,2不出现；
组合3：TCI0,1对应的指示信息指示其出现，TCI0,2对应的指示信息指示其不出现，类型指示符指示其为第二TCI状态，则TCI0,1出现、TCI0,2不出现；
组合4：TCI0,1对应的指示信息指示其出现，TCI0,2对应的指示信息指示其出现，类型指示符指示其为第二TCI状态，则TCI0,1出现、TCI0,2出现；
组合5：TCI0,1对应的指示信息指示其不出现，TCI0,2对应的指示信息指示其出现，类型指示符指示其为第二TCI状态，则TCI0,1不出现、TCI0,2出现。
方案三：通过DCI指示TCI状态的类型
可选地，DCI还用于指示第一信息中包含的TCI状态的类型。
在一些实施例中，在第一信息包括第二MAC CE和DCI时，若第二MAC CE没有指示TCI状态的类型，可以通过DCI进行指示。可选地，DCI可以指示TCI状态的类型为第一TCI状态和/或第二TCI状态。
可选地，DCI的格式为用于调度PDSCH的DCI格式。
用于调度PDSCH的DCI格式包括DCI format 1_0,DCI format 1_1,DCI format 1_2中的至少一项。
可选地，DCI中包含下行链路分配指示域(DCI format with DL assignment)，或者，不含下行链路分配指示域(DCI format without DL assignment)，下行链路分配指示域用于指示PDSCH传输资源。
在一些实施例中，若DCI包含下行链路分配指示域，表示DCI既用于指示第一信息中包含的TCI状态的类型，也用于指示PDSCH传输资源。
在一些实施例中，若DCI不包含下行链路分配指示域，表示DCI用于指示第一信息中包含的TCI状态的类型，但不用于指示PDSCH传输资源。
可选地，用于调度PDSCH的DCI格式，用于指示第一信息中包含的TCI状态的类型包括第一TCI状态和/或第二TCI状态。
在一些实施例中，用于调度PDSCH的DCI格式，可以指示TCI状态的类型均为第一TCI状态，还是均为第二TCI状态，还是包含有第一TCI状态和第二TCI状态。类似于上表1所示的情况。
可选地，用于调度PDSCH的DCI格式，用于指示第一信息中包含的TCI状态的类型包括第一TCI状态和/或下行传输专用的第二TCI状态。这种情况下，MAC CE中每个码点对于每个TRP最多对应一个TCI状态即可，码点用于指示各个TRP是第一TCI状态还是下行传输专用的第二TCI状态(即第二TCI状态中的separate DL TCI state)。
本公开实施例中，由于每个TRP最多对应一个TCI状态即可，若是第二TCI状态，则一定是下行传输专用的第二TCI状态，无需通过更多的信令开销来指示第二TCI状态是用于下行还是用于上行，从而进一步节省信令开销。
可选地，用于调度PDSCH的DCI格式，用于指示第一信息中包含的TCI状态的类型仅 包括下行传输专用的第二TCI状态。
可选地，DCI包含TCI状态类型指示域，TCI状态类型指示域用于指示DCI指示的TCI状态包括第一TCI状态，第二TCI状态和下行传输专用的第二TCI状态中的至少一种。
在一些实施例中，TCI状态类型指示域用于指示DCI指示的TCI状态仅包括第一TCI状态；或者，TCI状态类型指示域用于指示DCI指示的TCI状态仅包括第二TCI状态，其中，第二TCI状态是指separate DL TCI state和separate UL TCI state中的至少一种；或者，TCI状态类型指示域用于指示DCI指示的TCI状态仅包括下行传输专用的第二TCI状态；或者，TCI状态类型指示域用于指示DCI指示的TCI状态包括第一TCI状态和第二TCI状态；或者，TCI状态类型指示域用于指示DCI指示的TCI状态包括第一TCI状态和下行传输专用的第二TCI状态。
可选地，DCI的格式为用于调度PUSCH的DCI格式。
用于调度PUSCH的DCI格式包括DCI format 0_0,DCI format 0_1,DCI format 0_2中的至少一项。
在一些实施例中，TCI状态指示域可以复用Rel-16的一个SRI信息域，或复用Rel-17的两个SRI指示域中的至少一个。当复用Rel-17的两个SRI指示域时，可以使用不同的SRI对应不同的TRP，独立指示不同的码点，每个码点对应一个第一TCI状态或一组第二TCI状态。
可选地，DCI中包含上行链路分配指示域(DCI format with UL assignment)，或者，不包含上行链路分配指示域(DCI format without UL assignment)，上行链路分配指示域用于指示PUSCH传输资源。
在一些实施例中，若DCI包含上行链路分配指示域，表示DCI既用于指示第一信息中包含的TCI状态的类型，也用于指示PUSCH传输资源。
在一些实施例中，若DCI不包含上行链路分配指示域，表示DCI用于指示第一信息中包含的TCI状态的类型，但不用于指示PUSCH传输资源。
在一些实施例中，在DCI不包含上行链路分配指示域的情况下，在不需要使用的比特域(如原本用于指示上行资源的比特域)上，可以通过规定的符号，来表示DCI不包含上行链路分配指示域(或表示DCI不包含下行链路分配指示域)、而是仅用于指示第一信息中包含的TCI状态的类型，终端设备能够通过这些规定的符号检测出该DCI仅用于指示unified TCI state。可选地，规定的符号可以是0、1、0000、1111等等，本公开实施例对此不作具体限定。
在一些实施例中，unified TCI state还可以用于参考信号的传输。
可选地，用于调度PUSCH的DCI格式，用于指示第一信息中包含的TCI状态的类型包括第一TCI状态和/或第二TCI状态。
在一些实施例中，用于调度PUSCH的DCI格式，可以指示TCI状态的类型均为第一TCI状态，还是均为第二TCI状态，还是包含有第一TCI状态和第二TCI状态。类似于上表1所示的情况。
可选地，用于调度PUSCH的DCI格式，用于指示第一信息中包含的TCI状态的类型包括第一TCI状态和/或上行传输专用的第二TCI状态。这种情况下，MAC CE中每个码点对于每个TRP最多对应一个TCI状态即可，码点用于指示各个TRP是第一TCI状态还是上行传输专用的第二TCI状态(即第二TCI状态中的separate UL TCI state)。
本公开实施例中，由于每个TRP最多对应一个TCI状态即可，若是第二TCI状态，则一定是上行传输专用的第二TCI状态，无需通过更多的信令开销来指示是第二TCI状态是用于下行还是上行，从而进一步节省信令开销。
可选地，用于调度PUSCH的DCI格式，用于指示第一信息中包含的TCI状态的类型仅包括上行传输专用的第二TCI状态。
可选地，DCI包含TCI状态类型指示域，TCI状态类型指示域用于指示DCI指示的TCI状态包括第一TCI状态，第二TCI状态和上行传输专用的第二TCI状态中的至少一种。
在一些实施例中，TCI状态类型指示域用于指示DCI指示的TCI状态仅包括第一TCI状 态；或者，TCI状态类型指示域用于指示DCI指示的TCI状态仅包括第二TCI状态，其中，第二TCI状态是指separate DL TCI state和separate UL TCI state中的至少一种；或者，TCI状态类型指示域用于指示DCI指示的TCI状态仅包括上行传输专用的第二TCI状态；或者，TCI状态类型指示域用于指示DCI指示的TCI状态包括第一TCI状态和第二TCI状态；或者，TCI状态类型指示域用于指示DCI指示的TCI状态包括第一TCI状态和上行传输专用的第二TCI状态。
以上方案一至三为显式地指示TCI状态的类型，本公开实施例还提供了如下隐式地指示TCI状态的类型的方案：
可选地，第一信息中包括至少一组信息域，每组信息域包括第三信息域和第四信息域。
在一些实施例中，属于同一组信息域的第三信息域和第四信息域中承载的两个TCI状态相同。在一些实施例中，若同一组信息域的第三信息域和第四信息域中承载的两个TCI状态相同，就可以表示该组信息域中的TCI状态的类型为第一TCI状态。
在一些实施例中，属于同一组信息域的第三信息域和第四信息域中承载的两个TCI状态不同。在一些实施例中，若同一组信息域的第三信息域和第四信息域中承载的两个TCI状态不同，就可以表示该组信息域中的TCI状态的类型为第二TCI状态。
在一些实施例中，若第三信息域位于第四信息域之前，则表示第三信息域中承载的是下行传输专用的第二TCI状态、第四信息域中承载的是上行传输专用的第二TCI状态。
在一些实施例中，若第三信息域位于第四信息域之前，则表示第三信息域中承载的是上行传输专用的第二TCI状态、第四信息域中承载的是下行传输专用的第二TCI状态。
