图1示出了本申请一个实施例提供的通信系统的示意图。该通信系统可以包括：终端设备10和接入网设备20。
终端设备10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端设备10。终端设备10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它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
接入网设备20是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点。在采用不同的无线接入技术的系统中，具备接入网设备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。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为接入网设备。接入网设备20与终端设备10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备20的数量可以有多个，两个邻近的接入网设备20之间也可以通过有线或者无线的方式进行通信。终端设备10可以在不同的接入网设备20之间进行切换，也即与不同的接入网设备20建立连接。
可选地，接入网设备20上设置有至少两个TRP。终端设备10与至少两个TRP之间通过接收TCI状态和/或发送TCI状态来建立通信连接。可选地，不同的TRP使用不同的接收TCI状态和/或发送TCI状态。其中，每个TRP对应至少一种信道传输方式，例如，TRP1与终端设备10之间的信道为PDCCH，TRP2与终端设备10之间的信道为PUSCH。示例性的，终端设备10根据联合TCI状态或下行TCI状态确定接收PDCCH需要使用的接收TCI状态；终端设备10根据联合TCI状态或上行TCI状态确定发送PUSCH需要使用的发送TCI状态。
本申请实施例中的“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。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
在新的无线技术(New Radio，NR)中，特别是通信频段在频率范围2(frequency range 2)时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于TCI state的发送和接收。
示例性的，如图2所示，以PDCCH为例进行说明，PDCCH包括至少一个PDCCH候选(PDCCH candidate)，这里以一个PDCCH候选为例进行说明，PDCCH候选属于搜索空间集(Search Space set，SS set)，SS set用于描述PDCCH搜索的时域位置，而SS set又关联控制资源集(Control Resource SET，CORESET)，CORESET用于描述PDCCH的频域特性和时域占用的符号个数。因此，上述部分简要描述了PDCCH中PDCCH候选、SS set和CORESET之间的关联。
为了减少信令开销，希望使用统一TCI状态(unified TCI state)，基站如果指示一个用于下行的统一TCI状态，那么该TCI状态可以适用于终端的PDSCH和至少一部分PDCCH(比如终端专用的PDCCH(User Equipment dedicated PDCCH))以及一些下行参考信号；基站如果指示一个用于上行的统一TCI状态，那么该TCI状态可以适用于终端的PUSCH和至少一部分PUCCH以及一些上行参考信号。统一TCI状态目前可能是采用分离的上行TCI状态(Separate Up Link TCI State)和分离的下行TCI状态(Separate Down Link TCI State)分开指示，或者上下行联合TCI状态(Joint TCI State)采用联合指示。
其中，分离的上行TCI状态适用于上行的信道/参考信号，分离的下行TCI状态适用于下行的信道/参考信号。联合TCI状态用于同时适用于上下行的信道/参考信号。

可选地，TCI状态与TRP一一对应，多套TCI状态表示TCI状态的数量至少为2套，则与TCI状态对应的TRP的数量也至少为2个。
