如图2所示，本申请实施例提供一种TCI状态的指示方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端接收无线资源控制(Radio Resource Control，RRC)信令，所述RRC信令用于指示TCI状态的资源池和TCI状态的模式中的至少一项。
上述TCI状态的资源池可以包括多个TCI状态，还可以包括多种TCI状态，例如包括，联合(joint)TCI状态，分离(separate)TCI状态等。
本申请各个实施例中提到的联合TCI状态，可以是终端上下行传输采用统一的一套波束指示信息，即采用统一的一个联合TCI状态，一个联合TCI 状态可以应用于一个或多个信道或信号；本申请各个实施例中提到的分离TCI状态，每组分离TCI状态可以包括上行TCI状态和下行TCI状态，一个下行TCI状态应用于一个或多个下行信道或信号，一个上行TCI状态应用于一个或多个上行信道或信号。
上述TCI状态的模式可以包括联合指示或分离指示。
本申请各个实施例中提到的联合指示，可以是终端上下行传输采用统一的一套波束指示信息(如统一的一个联合TCI状态)；本申请各个实施例中提到的分离指示，可以是为终端指示一组分离TCI状态，分离TCI状态的下行TCI状态应用于下行信道或信号，分离TCI状态的上行TCI状态应用于上行信道或信号。
在多TRP场景中，终端或目标资源可以被指示多个联合TCI状态，每个联合TCI状态对应一个TRP；终端或目标资源还可以被指示多组分离TCI状态，每组分离TCI状态对应一个TRP。
S204：终端接收第一媒体接入控制控制单元(Media Access Control-Control Element，MAC CE)，所述第一MACCE用于激活与所述TCI状态的资源池或所述TCI状态的模式对应的至少一个TCI状态。
可选地，第一MAC CE包括如下至少之一：控制资源集资源池索引(CORESETPoolIndex)，探测参考信号(Sounding Reference Signal，SRS)资源集标识，天线面板标识，TCI状态的资源池标识，TCI状态的模式，至少一个码点信息。该实施例例如，第一MAC CE包括TRP标识，该TRP标识关联如下至少之一：CORESETPoolIndex，SRS资源集标识，面板标识，TCI状态的资源池标识，TCI状态的模式。同时第一MAC CE包含至少一个码点信息。
可选地，在S204之后，终端还可以确定用于目标资源传输的目标TCI状态。
本申请各个实施例提到的目标资源可以包括如下至少之一：物理下行控制信道(Physical Downlink Control Channel，PDCCH)，控制资源集(Control  Resource SET，CORESET)，搜索空间(Search Space，SS)，物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，物理上行控制信道(Physical Uplink Control Channel，PUCCH)，物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)，探测参考信号(Sounding Reference Signal，SRS)资源，SRS资源集。
在一个例子中，终端可以将所述第一MACCE激活的TCI状态中的预设TCI状态作为所述目标TCI状态，该预设TCI状态可以是以下至少一项：
1)第一MACCE中最小码点对应的TCI状态。
2)第一MACCE中包含多个TCI状态的最小码点对应的多个TCI状态。
3)第一MACCE中只包含一个TCI状态的最小码点对应的TCI状态。
4)第一MACCE中只包含一个下行/上行TCI状态的最小码点对应的TCI状态。
在另一个例子中，所述终端将所述第一MAC CE中预设码点关联的TCI状态为所述目标TCI状态。该预设码点可以参照上述1)至4)中介绍的最小码点。
在再一个例子中，在S204之后，终端还可以接收第二MACCE或第一下行控制信息(Downlink Control Information，DCI)，所述第二MACCE或所述第一DCI用于指示目标资源传输使用的目标TCI状态，所述目标TCI状态为所述第一MACCE激活的TCI状态中的至少一个。这样，后续终端即可根据第二MACCE或所述第一DCI的指示确定用于目标资源传输的目标TCI状态。为便于描述，后续还可以将第二MACCE和第一DCI统称为是第一命令。
该例子中，终端接收的第二MACCE或第一DCI可以用于指示TCI状态，第二MACCE或第一DCI指示的TCI状态可以包括如下至少之一：一个或多个联合TCI状态；一组或多组分离TCI状态，每组分离TCI状态可以包括上行TCI状态和下行TCI状态。
可选地，第二MACCE或第一DCI可以用于指示一个或多个TCI状态，每一个TCI状态可以应用于多个信道或信号。
在一个例子中，第二MACCE或第一DCI指示一个或多个联合TCI状态，该步骤可以包括：在所述第二MACCE或第一DCI指示一个联合TCI状态的情况下，将所述一个联合TCI状态作为所述目标资源使用的TCI状态；在所述第二MACCE或第一DCI指示多个联合TCI状态的情况下，将所述多个联合TCI状态中的第一目标联合TCI状态作为所述目标资源使用TCI状态。该例子中，第一目标联合TCI状态可以是第二MACCE或第一DCI指示的多个联合TCI状态中的第一个联合TCI状态或最后一个联合TCI状态等。
在另一个例子中，第二MACCE或第一DCI指示多个下行TCI状态和/或多个上行TCI状态，该步骤可以包括：在所述目标资源是下行资源的情况下，将所述多个下行TCI状态中的第一目标下行TCI状态作为所述目标资源使用的TCI状态；在所述目标资源是上行资源的情况下，将所述多个上行TCI状态中的第一目标下行TCI状态作为所述目标资源使用的TCI状态。该例子中，第一目标下行TCI状态可以是第二MACCE或第一DCI指示的多个下行TCI状态中的第一个下行TCI状态或最后一个下行TCI状态等；第一目标上行TCI状态可以是第二MACCE或第一DCI指示的多个上行TCI状态中的第一个上行TCI状态或最后一个上行TCI状态等。
本申请各个实施例提供的TCI状态的指示方法可以应用在统一的TCI架构中，可以灵活指示目标资源使用的TCI状态。其中，统一的TCI架构即为终端上下行传输采用统一的一套波束指示信息。例如，一种是上下行统一使用一个波束。当网络侧设备通过第二MACCE或第一DCI为终端指示了一个TCI状态，则上下行的多个信道或信号都可以应用该TCI状态(称作是联合TCI状态)。另一种方案是网络侧设备通过第二MACCE或第一DCI为终端指示一对波束，即两个TCI状态(即一组分离TCI状态)，一个下行TCI状态应用于下行信道或信号，一个上行TCI状态应用于上行信道或信号，这两个TCI状态可以称作是分离TCI状态。
本申请实施例提供的TCI状态的指示方法，终端接收RRC信令，该RRC信令用于指示TCI状态的资源池和TCI状态的模式中的至少一项，之后，终端接收第一MACCE，第一MACCE用于激活与所述TCI状态的资源池或所述TCI状态的模式对应的至少一个TCI状态。本申请实施例便于终端确定目标资源传输使用的目标TCI状态，终端还可以根据确定出的目标TCI状态传输目标资源，提高通信有效性。
可选地，前文各个实施例中的TCI状态的资源池满足如下至少之一：
1)所述TCI状态的资源池与控制资源集资源池索引(CORESETPoolIndex)关联。由于CORESETPoolIndex与TRP关联，因此，TCI状态的资源池也与TRP关联。
2)所述TCI状态的资源池与所述目标TCI状态关联。也即，终端确定出的目标TCI状态可以属于上述资源池中的TCI状态。
3)所述TCI状态的资源池与第二DCI的格式关联，所述第二DCI用于调度所述目标资源。该实施例中的第二DCI和前文中用于指示TCI状态的第一DCI可以是同一个DCI，还可以是不同的DCI。
4)所述TCI状态的资源池与所述TCI状态的模式关联。终端根据TCI状态的资源池，即可确定出TCI状态的模式。
5)所述TCI状态的资源池与目标资源关联。终端根据目标资源，即可选择TCI状态的资源池中的TCI状态。
可选地，前文各个实施例中的TCI状态的模式等满足如下至少之一：
1)所述TCI状态的模式与CORESETPoolIndex关联。由于CORESETPoolIndex与TRP关联，因此，TCI状态的模式也与TRP关联。
2)所述TCI状态的模式与所述目标TCI状态关联。也即终端可以确定出目标资源对应的目标TCI状态的模式。
3)所述TCI状态的模式与第二DCI的格式关联，所述第二DCI用于调度所述目标资源。终端根据第二DCI的格式，即可确定出TCI状态的模式。该实施例中的第二DCI和前文中用于指示TCI状态的第一DCI可以是同一个 DCI，还可以是不同的DCI。
4)所述TCI状态的资源池与所述TCI状态的模式关联。终端根据TCI状态的资源池，即可确定出TCI状态的模式。
5)所述TCI状态的模式与目标资源关联。终端根据目标资源，即可确定出用于传输该目标资源的TCI状态的模式。
上述两个实施例例如，第一MACCE对应的码点先关联的TCI状态对应TRP1，也就是对应先配置的TCI状态的资源池，以及先配置的TCI状态的模式；第一MACCE对应的码点后关联的TCI状态对应TRP2，也就是对应后配置的TCI状态的资源池，以及后配置的TCI状态的模式。
上述两个实施例中，网络侧设备可以配置TCI状态的模式是分离的还是联合的，这些模式可以与TRP关联，该TRP可以用TCI状态的资源池标识进行区分。
通过上述两个实施例介绍的关联关系，在多发送接收点/多天线面板(multi-TRP/multi-panel，M-TRP/TRP)场景中，可以基于终端的能力以及信道条件来针对不同TRP配置不同的TCI状态的模式，增加网络配置灵活性，同时也保证了上行传输的性能。
可选地，在多TRP的场景下，例如，在TRP的数量为2个的情况下，上述TCI状态的模式具体包含以下至少一种：1)两个TRP对应相同，都是联合指示；2)两个TRP对应相同，都是分离指示；3)两个TRP对应不同，第一个联合指示，第二个分离指示；4)两个TRP对应不同，第一个分离指示，第二个联合指示。
需要说明的是，本申请各个实施例中提到的TRP，可以显式的由TRP标识(ID)来标识，还可以由面板标识(Panel ID)来标识；或者隐式的用参考信号标识，用参考信号资源集标识等。
可选地，所述第一MACCE包括(N个，N是正整数)码点信息，所述码点信息用于指示要激活的TCI状态，(每个)所述码点信息包括如下至少之一：
1)从所述TCI状态的资源池中选择的所述激活的TCI状态的标识。
2)用于区分上行或下行的标识。
3)用于区分所述激活的TCI状态所属的TCI状态组的标识，通常，一个TCI状态组对应一个TRP。
