下面将结合本申请实施例中的附图，对本申请实施例进行阐述。
本申请实施例涉及的通信系统如图1所示，该通信系统可包括网络设备101、网络设备102和终端设备103，图1所示的设备数量和形态用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个以上的网络设备，一个以上的终端设备。图1所示的通信系统中，网络设备101和网络设备102均可向终端设备103提供服务。可选的，本申请实施例还可包括与网络设备101、网络设备102或终端设备103进行通信的其他设备，本申请实施例不做限定。
本申请可适用于第三代(3th Generation，3G)通信系统、第四代(4th Generation，4G) 通信系统或第五代(5th Generation，5G)通信系统，还可适用于未来新的各种通信系统，例如第六代(6th Generation，6G)通信系统、第七代(7th Generation，7G)通信系统等，本申请实施例对此并不限定。
本申请实施例中，网络设备也可称为接入网设备，是一种部署在无线接入网(wireless access network，RAN)中用以提供无线通信功能、基站功能或基站控制器功能的装置。在采用不同的无线接入技术的系统中，网络设备的名称可能不同。例如，在第二代移动通信(2th generation mobile communication，2G)网络中提供基站功能的设备包括基地无线收发站(base transceiver station，BTS)。3G网络中提供基站功能的设备包括节点B(NodeB)。在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)。在无线局域网络(Wireless Local Area Networks，WLAN)中，提供基站功能的设备为接入点(Access Point，AP)，或收发节点或发送接收点(transmission and reception point，TRP)、传输点(transmission point，TP)等。5G新无线(New Radio，NR)中的提供基站功能的设备为下一代基站节点(next generation node base station，gNB)，或继续演进的节点B(ng-eNB)，或网络设备的一个或一组天线面板，或者用于构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。本申请实施例中网络设备还包含在未来新的通信系统中提供基站功能的设备等，本申请不做限定。
本申请实施例中的基站控制器，也可以称为基站控制器设备，是一种管理基站的装置。例如，2G网络中的基站控制器(base station controller，BSC)、3G网络中的无线网络控制器(radio network controller，RNC)、未来新的通信系统中控制管理基站的装置。
本申请实施例中的终端设备，也可以称为终端，可以指各种形式的用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台(mobile station，MS)、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不限定。
目前，单TRP场景下的统一的TCI)state功能包括两种机制：JointULDL机制和SeparateULDL机制。其中，JointULDL是1个TCI state可适用于部分或者全部物理下行共享信道(Physical downlink shared channel，PDSCH)、部分或者全部物理下行控制信道(Physical  downlink control channel，PDCCH)、部分或者全部用于波束管理(beam management,BM)和/或信道状态信息获取的非周期信道状态信息参考信号(aperiodic channel state information reference signal,AP CSI-RS)、部分或者全部物理上行共享信道(Physical uplink shared channel，PUSCH)、部分或者全部物理上行控制信道(Physical uplink control channel，PUCCH)和部分或者全部SRS。SeparateULDL是2个TCI state中，一个TCI state适用于下行信道/信号，另一个TCI state适用于上行信道/信号。其中，下行信道/信号可以是部分或者全部PDSCH、部分或者全部PDCCH、部分或者全部用于BM和/或信道状态信息获取的AP CSI-RS；上行信道/信号可以是部分或者全部PUSCH、部分或者全部PUCCH和部分或者全部SRS。
但对于多(multiple)TRP协作场景，如何实现统一的TCI state的指示，以获知信道或信号关联的TCI state是一个亟待解决的问题。
本申请实施例中，信道的信道资源可以包括一个或多个时域单元(如符号、时隙等)以及一个或多个频域单元(如子载波、资源块等)。信号的资源集可以为参考信号资源集，其可以包括一个或多个参考信号资源，每个参考信号资源可以包括一个或多个端口，每个端口所映射的子载波和符号等。
需要说明的是，本申请实施例中，信道的信道资源也可以理解或简称为信道，信号的资源集也可以理解或简称为信号。相应的，信道的信道资源所属的第一集合可称为信道所属的第一集合，信号的资源集所属的第一集合可称为信号所属的第一集合。由于信道的各种关联关系是通过信道的信道资源进行配置关联的，故下文阐述中，优先以信道的信道资源所属的第一集合为例阐述该信道所属的第一集合，即无论是信道所属的第一集合，还是信道的信道资源所属的第一集合在本申请实施例中可互相替换。类似的，信号所属的第一集合以及信号的资源集所属的第一集合，两种表述在本申请实施例中可互相替换。本申请实施例提供一种通信方法100，该通信方法100可以获取信道或信号的第一信息，根据该第一信息确定信道的信道资源所属的第一集合，或根据该第一信息确定信号的资源集所属的第一集合。
其中，第一信息可以为以下实施方式中的任一种：
实施方式1.1.第一信息为信道或信号关联的控制资源集合(control resource set，CORESET)；
实施方式1.2.第一信息为信道或信号的第一参数配置，该第一参数配置用于配置该信道的信道资源所属的信道资源组，或者用于配置该信号的资源集；

实施方式1.4.第一信息为信道或信号的第二参数配置，第二参数配置用于配置信道的信道资源所属的第一集合，或者用于配置该信号的资源集所属的第一集合。
可见，该通信方法100中，终端设备可通过第一信息确定信道的信道资源或信号的资源集所属的第一集合，有利于结合每个第一集合关联的TCI state获知信道或信号关联的TCI state，进而实现多TRP协作场景下可靠的信道或信号的传输。
本申请还提供了一种通信方法200，该通信方法200可以接收下行控制信息(Downlink control information，DCI)或媒体接入控制(media access control,MAC)信息，所述DCI包括传输配置指示TCI字段，所述TCI字段用于指示一个或多个TCI状态，或指示一对或多对TCI状态；所述MAC信息用于配置一个或多个TCI状态，或配置一对或多对TCI状态；根据所述DCI或所述MAC信息，确定每个或每对TCI状态所属的第一集合。
可以理解的是，该通信方法200中，若终端设备被配置为JointULDL机制，所述一个或多个TCI状态中的任一个TCI状态可适用于部分或者全部的下行信道/信号，和部分或者全部的上行信道/信号。可以理解的是，若终端设备被配置为SeparateULDL机制，所述一对或多对TCI状态中的任一对TCI状态所包括的2个TCI状态分别适用于部分或者全部的下行信道/信号，和部分或者全部的上行信道/信号；或者所述一对或多对TCI状态中的任一对TCI状态所包括的1个TCI状态适用于部分或者全部的下行信道/信号，或部分或者全部的上行信道/信号。
可选的，终端设备根据所述DCI或所述MAC信息，确定每个或每对TCI状态所属的第一集合，可包括但不限于以下可选的实施方式：
实施方式2.1.根据每个TCI状态在所述TCI字段所指示的TCI状态或所述MAC信息中的位置或标识，确定所述每个TCI状态所属的第一集合；或者，根据每对TCI状态在所述TCI字段所指示的TCI状态或所述MAC信息中的位置或标识，确定每对TCI状态所属的第一集合。
实施方式2.2确定承载DCI的PDCCH所关联的CORESET；根据确定的CORESET，确定每个或每对TCI状态所属的第一集合。
可见，该通信方法200中，终端设备能够获知每个或每对TCI state与第一集合之间的关联关系，从而有利于结合信道或信号与第一集合之间的关联关系，而获知信道或信号关联的TCI state，进而实现多TRP协作场景下可靠的信道或信号的传输。
本申请还提供了通信方法300，该通信方法300可以根据所述DCI或所述MAC信息， 确定每个或每对TCI状态所属的第一集合，所述DCI包括TCI字段，所述TCI字段用于指示一个或多个TCI状态，或指示一对或多对TCI状态；所述MAC信息用于配置一个或多个TCI状态，或配置一对或多对TCI状态；确定信道的信道资源所属的第一集合，或信号的资源集所属的第一集合；根据所述信道的信道资源所属的第一集合或信号的资源集所属的第一集合，以及所述每个或每对TCI状态所属的第一集合，确定信道或信号关联的TCI状态。
其中，该通信方法300中，终端设备如何确定信道的信道资源所属的第一集合，或信号的资源集所属的第一集合的相关内容可参见通信方法100的相关阐述。终端设备如何根据DCI或MAC信息确定每个或每对TCI状态所属的第一集合的相关内容可参见通信方法200中的相关阐述。
另外，本申请实施例中，不同的第一集合表示不同的TRP，鉴于协议中表示TRP可能的方式，第一集合可包括但不限于以下几种可选的实施方式：
实施方式3.1.第一集合为CORESET组；
实施方式3.2.第一集合为信道探测参考信号(Sounding reference signal，SRS)资源集合；
实施方式3.3.第一集合为波束失败检测参考信号资源集合；
实施方式3.4.第一集合为PUSCH资源集合。

需要说明的是，本申请中的TRP可以与空域信息或空位方向(例如一个或一组波束)关联，或者，TRP可以通过空域信息或空位方向(例如一个或一组波束)表征。此外，本申请中的TRP可以是一个功能模块(例如：采用软件功能实现)，也可以通过硬件实现，本申请并不对TRP的实现方式进行限制。
以下结合附图对本申请提供的通信方法100至300进行阐述，其中，本申请实施例是从网络设备与终端设备之间交互的角度进行阐述。
请参阅图2，图2是本申请实施例提供的通信方法100的流程示意图。如图2所示，该通信方法100可包括但不限于以下步骤：
S101、终端设备获取信道或信号的第一信息。
一种可选的实施方式中，终端设备可从网络设备接收该信道或信号的第一信息。另一种可选的实施方式中，终端设备可根据网络配置信息确定信道或信号的第一信息。进一步的，可结合下述的实施方式1.1至1.4分别具体阐述第一信息的获取方式。
S102、终端设备根据第一信息，确定信道的信道资源所属的第一集合，或确定信号的资 源集所属的第一集合。
实施方式1.1，如上述所述，第一信息为信道或信号关联的CORESET。
可选的，信道可以为以下至少一种：PDCCH，PDSCH，PUSCH，PUCCH。
可选的，信号可以为AP CSI-RS。可选的，该AP CSI-RS可以是用于波束管理的AP CSI-RS，也可以是用于CSI获取的AP CSI-RS。
可选的，信道为PDSCH或PUSCH的情况，信道关联的CORESET是调度或激活信道的PDCCH关联的CORESET，相应的，终端设备可根据调度或激活信道的PDCCH关联的CORESET确定信道关联的CORESET。例如，PUSCH关联的CORESET是调度该PUSCH的PDCCH关联的CORESET。再例如，PDSCH关联的CORESET是调度该PDSCH的PDCCH关联的CORESET。再例如，PUCCH关联的CORESET可以是触发或者调度该PUCCH的PDCCH所关联的CORESET。
其中，上述所述的PDCCH关联的CORESET是包含此PDCCH的搜索空间所配置的CORESET。例如，包括第一PDCCH的搜索空间配置的CORESET包括第一CORESET，那么，该第一PDCCH关联的CORESET就是该第一CORESET。
可选的，信号为CSI-RS的情况，CSI-RS关联的CORESET可以是调度或者触发该CSI-RS的PDCCH关联的CORESET。
该实施方式中，第一集合如实施方式3.1所述为CORESET组，即不同CORESET组表示不同的TRP，那么，信道的信道资源所属的第一集合为信道关联的CORESET所属的CORESET组，或信号的资源集所属的第一集合为该信号关联的CORESET所属的CORESET组。也就是说，信道的信道资源所属的TRP为信道关联的CORESET所属的CORESET组表示的TRP，或信号的资源集所属的TRP为该信号关联的CORESET所属的CORESET组表示的TRP。
可选的，不同CORESET组是与不同控制资源集池索引关联的CORESET集合。例如，CORESET组1可以是关联于控制资源集合池索引coresetPoolIndex＝0的CORESET集合，CORESET组2可以是关联于coresetPoolIndex＝1的CORESET集合。
可选的，网络设备可发送各CORESET的参数配置，每个CORESET的参数配置用于配置该CORESET所属的CORESET组；终端设备可接收各CORESET的参数配置，进而获知各CORESET所属的CORESET组。
实施方式1.2.第一信息为信道或信号的第一参数配置，该第一参数配置用于配置该信道 的信道资源所属的信道资源组，或者用于配置该信号的资源集。
其中，网络设备发送信道或信号的第一参数配置，终端设备可接收信道或信号的第一参数配置。不同的所述信道资源组关联不同的第一集合；或者，不同的所述资源集关联不同的第一集合。也就是说，网络设备可对信道的信道资源进行分组，获得多个信道资源组，进而，通过第一参数配置告知终端每个信道的信道资源所属的信道资源组。
