应当理解，尽管在本申请实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”及“若”可以被解释成为“在……时”或“当……时”或“响应于确定”。
为了便于理解，首先介绍本申请涉及的术语。
1、物理层下行控制信道(physical downlink control channel，PDCCH)
PDCCH是一种物理信道，用于承载下行控制信息(downlink control information，DCI)，DCI可以包括上下行资源分配、混合自动重传请求(hybrid automatic repeat request，HARQ)信息、功率控制等。
2、媒体访问控制(Media Access Control，MAC)层
MAC层主要负责控制与连接物理层的物理介质。在发送数据的时候，MAC协议可以事先判断是否可以发送数据，如果可以发送将给数据加上一些控制信息，最终将数据以及控制信息以规定的格式发送到物理层；在接收数据的时候，MAC协议首先判断输入的信息是否发生传输错误，如果没有错误，则去掉控制信息并发送至逻辑链路控制层。

下面结合附图对本申请所提供的动态选择TRP的方法及其装置进行详细地介绍。
图2为本申请一实施例的动态选择TRP的方法的流程示意图，该方法应用于终端设备，如图2所示，该方法包括：
S201，接收网络设备发送的控制信令。
终端设备可以接收网络设备发送的控制信令，其中，控制信令用于指示终端设备从多个TRP中确定出为其服务的一个或多个目标TRP。可选地，控制信令可以为高层控制信令，例如MAC CE信令，终端设备接收网络设备发送的MAC CE信令，其中，该MAC CE信令用于指示终端设备从多个TRP中确定出为其服务的一个或多个目标TRP。
以控制信令为MAC CE信令为例，在一些实现中，控制信令可以为新构造的MAC CE信令。
作为一种可能的实现方式，MAC CE信令中至少包括控制资源集池的索引对应的状态信息位。
作为另一种可能的实现方式，MAC CE信令中至少包括第一控制资源集的标识和TCI state的状态标识。需要说明的是，第一控制资源集的标识和TCI state的状态标识的数量为一个或多个。
在另一些实现中，控制信令可以为现有的MAC CE信令，该现有的MAC CE用于指示PDCCH对应的目标波束。
S202，根据控制信令，从多个TRP中确定用于为终端设备提供服务的一个或多个目标TRP。
作为一种可能的实现方式，MAC CE信令中包括控制资源集池的索引对应的状态信息位，基于控制资源集池的索引对应的状态信息位，从多个TRP中确定用于为终端设备提供服务的一个或多个目标TRP。
作为另一种可能的实现方式，MAC CE信令中包括至少一个第一控制资源集的标识和TCI state的状态标识，基于至少一个第一控制资源集的标识，从多个TRP中确定用于为终端设备提供服务的一个或多个目标TRP。
作为另一种可能的实现方式，现有的用于指示PDCCH对应的目标波束的MAC CE信令，可以包括网络设备为终端设备配置的目标TRP对应的第二控制资源集的标识，基于目标TRP对应的第二控制资源集的标识，从多个TRP中确定用于为终端设备提供服务的一个或多个目标TRP。
需要说明的是，可以选择Q个目标TRP，Q的取值取决于终端设备的能力，本申请中，且必须至少选择一个为终端设备提供服务的小区中的TRP，Q的取值可以为大于或者等于1的正整数。
本申请实施例提供一种动态选择传输接收点TRP的方法，通过引入控制信令，可以在多个TRP中 为UE动态地选择最佳的一个或多个TRP为UE提供服务，以提高系统吞吐量。
图3为本申请一实施例的动态选择TRP的方法的流程示意图，该方法应用于终端设备，如图3所示，该方法包括：
S301，接收网络设备发送无线资源控制RRC信令，RRC信令包括为终端设备配置的控制资源集和/或控制资源集池的索引。
实现中控制资源集集中配置该控制资源集相应的控制资源集池的索引。若未为每个控制资源集配置相应的控制资源集池的索引，则针对未配置相应的控制资源集池的索引的控制资源集，这些控制资源集中用于携带控制资源集池的索引所在信息域默认为0。
终端设备接收网络设备发送无线资源控制(radio resource control，RRC)信令，网络设备通过RRC信令为终端设备预配置M个控制资源集(CORESET)，为其配置N个控制资源集池的索引(CORESETPoolIndex)，对应N个TRP，其中，M≥N。也就是说，一个控制资源集池的索引可能对应多个控制资源集，每一个控制资源集池的索引对应一个TRP，M和N为正整数。
S302，接收网络设备发送的控制信令。
终端设备在接收到RRC信令后，接收网络设备发送的控制信令，其中，控制信令用于指示终端设备从多个TRP中确定出为其服务的一个或多个目标TRP。可选地，控制信令可以为高层控制信令，例如MAC CE信令，在一些实现中，控制信令可以为新构造的MAC CE信令；在另一些实现中，控制信令可以为现有的MAC CE信令，该现有的MAC CE用于指示PDCCH对应的目标波束。
关于MAC CE信令的具体实现方式可参见本申请各实施例中相关内容的记载，此处不再赘述。
S303，根据控制信令，从多个TRP中确定用于为终端设备提供服务的一个或多个目标TRP。
关于步骤S303的具体实现方式可参见本申请各实施例中相关内容的记载，此处不再赘述。
本申请实施例提供一种动态选择TRP的方法，为终端设备配置控制资源集和/或控制资源集池的索引，以上述配置信息的状态确定目标TRP，通过这种方式，可以在多个TRP中精准选择出所需要的目标TRP。
图4为本申请一实施例的动态选择传输接收点TRP的方法的流程示意图，该方法应用于终端设备，如图4所示，该方法包括：
S401，接收网络设备发送的第一控制信令，其中，第一控制信令包括控制资源集池的索引对应的状态信息位。
此处的第一控制信令即为步骤S201中的控制信令的具体实现。
接收网络设备发送的第一控制信令，其中，第一控制信令为一个新构建的MAC CE信令。根据下述步骤S400中RRC信令配置的控制资源集池的索引，第一控制信令携带每个索引相应的状态信息位。如图5所示，T 0～T N为控制资源集池的索引的状态信息位，可选地，T i的值为0或1。
S402，根据状态信息位的取值，从多个TRP中确定至少一个目标TRP。
控制资源集池索引与TRP之间有一对一的映射关系，当状态信息位的取值为1，即T i＝1，表示选择该控制资源集池的索引对应的TRP，反之不选择该TRP。
本申请实施例提供一种动态选择TRP的方法，还可以包括以下步骤：
S400，接收网络设备发送RRC信令，RRC信令包括为终端设备配置的控制资源集和/或控制资源集池的索引。关于步骤S400的具体实现方式可参见本申请各实施例中相关内容的记载，此处不再赘述。
本申请实施例提供一种动态选择TRP的方法，基于第一控制信令中控制资源集池的索引对应的状态信息位的值，以及索引与TRP之间的映射关系，在多个TRP中精准选择出所需要的目标TRP。
图6为本申请一实施例的动态选择TRP的方法的流程示意图，该方法应用于终端设备，如图6所示，该方法包括：
S601，接收网络设备发送的第二控制信令，其中，第二控制信令至少包括第一控制资源集的标识。
可选地，控制信令为第二控制信令，本申请中终端设备接收网络设备发送的第二控制信令，其中，第二控制信令为一个新构建的MAC CE信令。第二控制信令包括至少一个第一控制资源集的标识，以及指示传输配置指示TCI状态(State)的第一状态标识，如图7所示。需要说明的是，第一控制资源集的标识和TCI state的状态标识的数量为一个或多个。
S602，根据第一控制资源集的标识，从多个TRP中确定目标TRP。
本申请实施例中，终端设备可以接收网络发送的RRC信令，RRC信令包括为终端设备配置的控制资源集和/或控制资源集池的索引。关于终端设备可以接收网络发送的RRC信令的具体介绍，可参见本申请各实施例中相关内容的记载，此处不再赘述。
作为一种可能的实现方式，RRC信令还包括控制资源集的标识范围与多个TPR之间的映射关系。在配置中，一个控制资源集池的索引可能对应多个控制资源集，每一个控制资源集池的索引对应一个TRP。在本申请实施例中，每个控制资源集有各自的标识，例如，当标识范围为0-3的控制资源集对应一个索引，标识范围为4-6的控制资源集对应另一个索引时，标识范围为0-3的控制资源集对应一个TRP，标识范围为4-6的控制资源集对应另一个TRP。
本申请实施例中，可以根据RRC信令中携带的控制资源集的标识范围与多个TPR之间的映射关系确定目标TRP。每个TRP对应不同的控制资源集的标识范围，确定第一控制资源集的标识所处的目标标识范围，并根据目标标识范围确定目标TRP。例如，标识范围为0-3的控制资源集对应TRP1，标识范围为4-6的控制资源集对应TRP2，当第一控制资源集的标识为2时，属于0-3的标识范围，确定目标TRP为TRP1。
本申请实施例提供一种动态选择TRP的方法，还可以包括以下步骤：
S603，根据第二控制信令中指示的TCI状态的第一状态标识，确定目标TRP对应的PDCCH的目标波束。
在一些实现中，TCI State ID中包括参考信号，参考信号与波束(beam)关联，因此，从第二控制信令中获取到TCI第一状态标识后，可以获取到第一状态标识中的参考信号，将该参考信号关联的beam，确定为目标TRP对应的PDCCH的目标波束。
本申请实施例提供一种动态选择TRP的方法，基于新构建的第二控制信息中携带的控制资源集的标识，在多个TRP中精准选择出所需要的目标TRP，并基于第二控制信息中携带的TCIState的第一状态信息，在选择目标TRP的同时为选择的TRP的PDCCH指示目标波束。
图8为本申请一实施例的动态选择TRP的方法的流程示意图，该方法应用于终端设备，如图8所示，该方法包括：
S801，接收网络设备发送的现有用于指示PDCCH对应的目标波束的第三控制信令，其中，第三控制信令包括网络设备为终端设备配置的目标TRP对应的第二控制资源集的标识。
此处第三控制信令即为步骤S201中的控制信令的具体实现。
第三控制信令可以为复用现有的用于指示PDCCH对应的目标波束的MAC CE信令。在一些实现中，现有的用于指示PDCCH对应的目标波束的MAC CE信令，如图9所示，该MAC CE信令包括控制资源集的标识、服务小区标识和TCI状态的状态标识。本申请实施例中，MAC CE信令中包括的控制资源集的标识为网络设备为终端设备配置的目标TRP对应的第二控制资源集的标识。可选地，第二控制资源集可以为服务小区对应的控制资源集，也可以为非服务小区的控制资源集。
S802，根据第二控制资源集的标识，从多个TRP中确定用于为终端设备提供服务的目标TRP。
TRP可能的切换场景如图10所示，当前为终端设备提供服务的TRP可以从服务小区变更到非服务小区的TRP，还可以从非服务小区的TRP变更至服务小区的TRP，还可以是从一个非服务小区的TRP变更到另一个非服务小区的TRP。
作为一种可能的实现方式，在终端设备变更TRP时，为了保证终端设备必须有一个服务小区的TRP，需要确定当前为终端设备提供服务的TRP所属小区类型，进一步地，基于TRP所属小区类型和第二控制资源集的标识，从多个TRP中确定用于为终端设备提供服务的目标TRP。
在一些实现中，根据TRP所属小区类型，确定出当前为终端设备提供服务的TRP均为服务小区的TRP，则确定当前为终端设备提供服务的TRP中用于发送第三控制信令的TRP为保留TRP，并将另一个TRP变更至第二控制资源集的标识指示的目标TRP，此处另一个TRP是指为UE提供服务的小区的TRP中除保留TRP之外的TRP。
在另一些实现中，根据TRP所属小区类型，确定出当前为终端设备提供服务的TRP中包括服务小区的TRP和非服务小区的TRP，则确定服务小区的TRP为保留TRP，并将非服务小区的TRP切换至第 二控制资源集的标识指示的目标TRP。
第二控制资源集的标识所指示的目标TRP可能为服务小区的TRP，也可能为非服务小区的TRP。可以基于第二控制资源集的标识关联的控制资源集池的索引来确定第二控制资源集的标识所指示的目标TRP。
需要说明的是，可以根据提供服务的控制资源集对应的TCI状态列表确定当前为终端设备提供服务的TRP所属小区类型。若TCI状态列表中的TCI State的状态标识属于服务小区，则确定为终端设备提供服务的TRP所属小区类型为服务小区；若TCI状态列表中的TCI State的状态标识属于非服务小区，则确定为终端设备提供服务的TRP所属小区类型为非服务小区。
本申请实施例提供一种动态选择TRP的方法，根据不同的情况选择需要切换的TRP，通过这种方式，可以在多个TRP中为终端设备选择最佳的TRP为其提供服务。
图11为本申请一实施例的动态选择TRP的方法的流程示意图，该方法应用于终端设备，如图11所示，该方法包括：
S1101，接收网络设备发送的RRC信令，RRC信令中携带的控制资源集池的索引包括控制资源集池的第一索引和控制资源集池的第二索引。
本申请实施例中，接收网络设备发送的RRC信令，通过RRC信令为终端设备预配置M个控制资源集，为其配置2个控制资源集池的索引，2个控制资源集池的索引分别为控制资源集池的第一索引(CORESETPoolIndex#0)和控制资源集池的第二索引(CORESETPoolIndex#1)。也就是说，M个控制资源集部分CORESET与CORESETPoolIndex#0关联，M个控制资源集中的另一部分CORESET与CORESETPoolIndex#1关联。
S1102，接收网络设备发送的现有用于指示PDCCH对应的目标波束的第三控制信令，其中，第三控制信令包括网络设备为终端设备确定的目标TRP对应的第二控制资源集的标识。
此处第三控制信令为步骤S201中控制信令的具体实现。
关于步骤S1102的具体实现方式可参见本申请各实施例中相关内容的记载，此处不再赘述。
S1103，根据第二控制资源集的标识，确定第二控制资源集对应的TCI状态列表。
由于每个控制资源集对应有一个TCI状态列表，因此在获取到第二控制资源集的标识，可以基于标识确定出第二控制资源集对应的TCI状态列表。
S1104，根据第三控制信令中指示一个TCI状态的第二状态标识，从对应的TCI状态列表中确定PDCCH的目标波束。
本申请实施例中，TCI状态列表中包括多个TCI状态的状态标识对应的波束，基于第二状态标识，可以从第二控制资源集对应的TCI状态列表中，确定出该第二状态标识对应的波束，将该第二状态标识对应的波束确定为PDCCH的目标波束。进一步地，终端设备切换至目标波束进行PDCCH传输。
本申请实施例提供一种动态选择TRP的方法，还包括以下步骤：
可选地，终端设备确定与控制资源集池的第一索引关联的所有控制资源集对应的第一TCI状态列表。也就是说，由于CORESET与不同CORESETPoolIndex关联，在获取到CORESETPoolIndex#0后，可以确定出与CORESETPoolIndex#0关联的CORESET，并确定出CORESETPoolIndex#0关联的CORESET对应的第一TCI状态列表。
可选地，终端设备确定与控制资源集池的第二索引关联的所有控制资源集对应的第二TCI状态列表。也就是说，获取到CORESETPoolIndex#1后，可以确定出与CORESETPoolIndex#1关联的CORESET，并确定出CORESETPoolIndex#1关联的CORESET对应的第二TCI状态列表。
需要说明的是，第一TCI状态列表和第二TCI状态列表中一个列表中包括服务小区的TCI状态，另一个列表中包括服务小区和非服务小区的TCI状态。在一些实现中，可以是第一TCI状态列表中包括服务小区的TCI状态，第二TCI状态列表包括服务小区和非服务小区的TCI状态。在另一些实现中，可以是第一TCI状态列表中包括服务小区的TCI状态和非服务小区的TCI状态，第二TCI状态列表包括服务小区。
举例说明，与CORESETPoolIndex#0关联的CORESET对应的第一TCI状态列表中包括服务小区的TCI状态，与CORESETPoolIndex#1关联的CORESET对应的第二TCI状态列表中包括服务小区和非服 务小区的TCI状态。
需要说明的是，本申请中非服务小区TCI state指的是TCI state内关联的参考信号为非服务小区的参考信号。
本申请实施例提供一种动态选择TRP的方法，通过为控制资源集分配控制资源集池的第一索引和控制资源集池的第二索引，可以根据需要为终端设备指示不同TRP的TCI状态。
图12为本申请一实施例的动态选择TRP的方法的流程示意图，该方法应用于终端设备，如图12所示，该方法包括：
S1201，响应于未获取到控制信令。
终端设备接收到RRC信令的配置信息后，没有接收到MAC CE信令包含的TRP选择控制信令。
S1202，将控制资源集池的目标索引对应的TRP确定为目标TRP。
默认控制资源集池的索引值为0的TRP是被选择的，将其确定为目标TRP，并不通过其他控制资源集的配置参数去接收其他PDCCH。
相关技术中，若未获取到控制信令，则将所有TRP确定为目标TRP，导致超出终端设备的处理能力，而本公开实施例的方法可以将目标TRP的数量控制在终端设备可以处理的能力范围之内，提高系统吞吐量。
本申请实施例提供一种动态选择TRP的方法，说明了在未获取控制信令时TRP的确定方法，保证了终端设备在无控制信令时也能确定为其服务的TRP。

S1301，向终端设备发送RRC信令，RRC信令包括为终端设备配置的控制资源集和/或控制资源集的池索引。
