具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、射频拉远头(Remote Radio Head，RRH)
在远端将基带光信号转成射频信号放大传送出去。也可称为射频拉远模块(Remote Radio Unit，简称RRU)。
2、传输配置指示(transmission configuration indication，TCI)
用于告知终端设备接收物理下行控制信道(physical downlink control channel，PDCCH)、物理下行共享信道(physical downlink shared channel，PDSCH)使用与接收网络设备发送的哪个同步信号块(Synchronization Signal Block，SSB)或信道状态信息参考信号(channel state information reference signal，CSI-RS)一样的接收beam.
或者，用于告知终端设备发送物理上行控制信道(physicaluplink control channel，PUCCH)、物理上行共享信道(physicaluplink shared channel，PUSCH)使用与发送哪个参考信号，比如探测参考信号(sounding reference signal，SRS)，一样的发送beam。或用于告知终端设备发送PUCCH、PUSCH使用与接收哪个参考信号，比如SSB或CSI-RS的接收beam对应的发送beam。
3、媒体接入控制(medium access control,MAC)控制单元(Control Element，CE)

4、下行控制信息(Downlink Control Information，DCI)
DCI为在PDCCH信道传输的、与物理上下行共享信道(PUSCH、PDSCH)相关的控制信息，这些DCI信息包含了诸如资源块(resource block，RB)分配信息、调制方式等等若干相关内容。终端只有正确的解码到了DCI信息，才能正确的处理PDSCH数据或PUSCH数据。
为了更好的理解本公开实施例公开的一种传输配置指示状态的确定方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备、一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备11、一个终端设备12。

下面结合附图对本公开所提供的传输配置指示状态的确定方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种传输配置指示状态的确定方法的流程示意图,该方法由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，接收媒体接入控制MAC控制单元CE，其中，MAC CE用于激活至少一个射频拉远头RRH对应的传输配置指示TCI状态state。
可以理解的是，在网络设备中包含多个RRH的情况下，网络设备可以为设备终端配置对应多个射频拉远头的不同的TCI state，并通过配置信息，将每个RRH对应的TCI state发送给终端设备，之后，即可根据需要，利用MAC CE激活RRH对应的TCI state,进而终端设备即可确定RRH对应的TCI state，即确定接收该RRH对应的PDCCH、PDSCH使用的beam，或者，发送PUCCH,PUSCH使用的beam。
可选的，RRH可以对应以下至少一项：RRH标识(Identity document,ID)，发送接收点(transmission reception point，TRP)标识，控制资源集池索引(CORESETPoolIndex)，参考信号资源集合ID，以及参考信号资源ID。也就是说，在本发明实施例中，RRH可以与TRP、CORESETPoolIndex、参考信号资源集合或参考信号资源互换。
可选的，TCI state为以下至少一项：联合TCI状态，独立的下行TCI状态，以及独立的上行TCI状态，其中，联合TCI状态同时用于上行和下行传输。
可选的，不同的RRH可以对应相同的物理小区标识(Physical Cell Identifier，PCI)，或者，不同的射频拉远头也可以对应不同的PCI，本公开对此不做限定。
通过实施本公开实施例，终端设备通过接收用于激活至少一个RRH对应的TCI state 的MAC CE，即可确定RRH对应的波束，从而不仅保证了多个RRH可以同时为终端设备提供服务，提高了射频拉远头的利用率，而且保证了信号的覆盖范围。
请参见图3，图3是本公开实施例提供的一种传输配置指示状态的确定方法的流程示意图,该方法由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，接收MAC CE，其中，MAC CE用于激活TCI域field的L个码点codepoint分别对应的M个TCI state，L个codepoint均与同一个控制资源集池索引关联，L和M，分别为正整数。
可选的，一个控制资源集池索引(CORESETPoolIndex)可以对应一个或多个RRH。比如，RRH1和RRH2可以同时对应同一个CORESETPoolIndex。或RRH1对应CORESETPoolIndex1，RRH2对应CORESETPoolIndex2。
需要说明的是，本实施例中的MAC CE，可以为多个，比如，2个，3个等等，本公开对此不做限定。每个MAC CE可以激活与之关联的一个CORESETPoolIndex中包含的TCI field的L个codepoint分别对应的M个TCI state。不同的MAC CE可以激活不同的CORESETPoolIndex对应的TCI state。
可选的，终端设备也可以根据MAC CE，确定每个TCI state对应的控制资源集池索引和/或RRH标识。
举例来说，本实施例中，任一个MAC CE激活的控制资源集池索引对应的TCI state，可以如表1所示。
表1
Figure PCTCN2021119699-appb-000001
其中，CORESETPoolIndex为MAC CE激活的控制资源集池索引；TCI codepoint#0、TCI codepoint#1、TCI codepoint#2等分别为TCI field中包含的codepoint；TCI(0,1)、TCI(0,2)、TCI(0,3)等为TCI codepoint#0对应的TCI state；TCI(1,1)、TCI(1,2)、TCI(1,3)等为TCI codepoint#1对应的TCI state；TCI(2,1)、TCI(2,2)、TCI(2,3)等为TCI codepoint#2对应的TCI state等等。需要说明的是，每个TCI codepoint对应的TCI state的个数可以为最多X个，X可以为2，或3或4，甚至更大，本发明不做限制。表1给出的每个TCI codepoint对应的TCI state的个数为3只是个示例。
可以理解的是，表1中的每一个元素、每一条对应关系，都是独立存在的；这些元素、对应关系被示例性的列在同一张表格中，但是并不代表表格中的所有元素、对应关系必须根据表1中所示的同时存在。其中每一个元素的值和每一对应关系，是不依赖于表1中任 何其他元素值或对应关系。因此本领域内技术人员可以理解，该表1中的每一个元素的取值、每一条对应关系，各种都是一个独立的实施例。
步骤32，接收下行控制信息DCI，其中，DCI用于指示L个codepoint中的其中一个codepoint。
可选的，DCI可以指示L个codepoint中的其中一个codepoint，从而终端设备根据该codepoint和MAC CE指示的该codepoint与TCI state的对应关系，确定该codepoint对应的一个或多个TCI state。
需要说明的是，在L等于1的情况下，终端设备只需根据MAC CE，即可确定RRH对应的TCI state，即RRH对应的波束。在L的值大于1的情况下，比如，L为2、或3，终端设备需要在接收网络设备发送的MAC CE之后，再根据网络设备发送的DCI信息，从L个codepoint中确定DCI指示的codepoint，之后即可根据该codepoint对应的TCI state，确定RRH对应的波束。
通过实施本公开实施例，终端设备首先接收用于激活TCI域field的L个码点codepoint分别对应的M个TCI state的MAC CE，L个codepoint均与同一个控制资源集池索引关联，之后在L大于1的情况下，再根据DCI指示的codepoint确定对应的TCI状态，进而确定RRH对应的波束，从而不仅保证了多个RRH可以同时为终端设备提供服务，提高了射频拉远头的利用率，而且保证了信号的覆盖范围。
请参见图4，图4是本公开实施例提供的一种传输配置指示状态的确定方法的流程示意图,该方法由终端设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤41，接收MAC CE，其中，MAC CE用于激活TCI域field的N个codepoint分别对应的K个TCI state，N个码点codepoint与N个控制资源集池索引一一关联，N个控制资源集池索引中的任意两个控制资源集池索引相同或不同，N和K分别为正整数。
可选的，一个控制资源集池索引可以对应一个或多个RRH。比如，RRH1和RRH2可以同时对应同一个CORESETPoolIndex。或RRH1对应CORESETPoolIndex1，RRH2对应CORESETPoolIndex2。
可选的，终端设备可以根据MAC CE，确定每个TCI state对应的控制资源集池索引和/或RRH标识。
可以理解的是，本公开实施例中的MAC CE可以为1个，这一个MAC CE可以激活多个RRH对应的TCI域field的N个codepoint分别对应的K个TCI state。
可选的，每个TCI field的codepoint对应的RRH标识独立指示。即每个TCI field的codepoint可以对应不同的RRH。
举例来说，本实施例中，任一个MAC CE激活的控制资源集池索引对应的TCI state，可以如表2所示。
表2
Figure PCTCN2021119699-appb-000002
Figure PCTCN2021119699-appb-000003
其中，如表2所示，终端设备在接收到该MAC CE后，即可确定：TCI(0,1)、TCI(0,2)、TCI(0,3)等为CORESETPoolIndex#0对应的TCI state，TCI codepoint#0与CORESETPoolIndex#0关联；TCI(1,1)、TCI(1,2)、TCI(1,3)等为CORESETPoolIndex#1对应的TCI state，TCI codepoint#1与CORESETPoolIndex#1关联；TCI(2,1)、TCI(2,2)、TCI(2,3)等为CORESETPoolIndex#1对应的TCI state，TCI codepoint#2与CORESETPoolIndex#2关联等等。当不同RRH对应不同CORESETPoolIndex时，每个TCI codepoint对应的CORESETPoolIndex都可以独立配置，即不同TCI codepoint可以对应相同的CORESETPoolIndex或不同的CORESETPoolIndex。也代表着不同TCI codepoint可以对应相同的RRH或不同的RRH。
可以理解的是，表2中的每一个元素、每一条对应关系，都是独立存在的；这些元素、对应关系被示例性的列在同一张表格中，但是并不代表表格中的所有元素、对应关系必须根据表2中所示的同时存在。其中每一个元素的值和每一对应关系，是不依赖于表2中任何其他元素值或对应关系。因此本领域内技术人员可以理解，该表2中的每一个元素的取值、每一条对应关系，各种都是一个独立的实施例。
步骤42，接收下行控制信息DCI，其中，DCI用于指示N个codepoint中的其中一个codepoint。
其中，步骤42的具体实现形式，可参照本公开中其他各实施例中的详细描述，此处不再详细赘述。
通过实施本公开实施例，终端设备首先接收用于激活TCI域field的N个codepoint分别对应的K个TCI state的MAC CE，N个码点codepoint与N个控制资源集池索引一一关联，之后在L大于1的情况下，再根据DCI指示的codepoint确定对应的TCI状态，确定RRH对应的波束，从而不仅保证了多个RRH可以同时为终端设备提供服务，提高了射频拉远头的利用率，而且保证了信号的覆盖范围。
请参见图5，图5是本公开实施例提供的一种传输配置指示状态的确定方法的流程示意图,该方法由终端设备执行。如图5所示，该方法可以包括但不限于如下步骤：

可选的，一个控制资源集池索引(CORESETPoolIndex)可以对应一个或多个RRH。比如，RRH1和RRH2可以同时对应同一个CORESETPoolIndex。或RRH1对应CORESETPoolIndex1，RRH2对应CORESETPoolIndex2。
可选的，终端设备可以根据MAC CE，确定每个TCI state对应的CORESETPoolIndex和/或RRH标识。
可以理解的是，本公开实施例中的MAC CE可以为1个，这一个MAC CE可以激活多个RRH对应的TCI域field的N个codepoint分别对应的K个TCI state。
可选的，在使用独立的上行TCI state，和/或多个独立的下行TCI state时，TCI field的同一个codepoint对应的独立的下行TCI state对应一个CORESETPoolIndex，独立的上 行TCI state对应一个CORESETPoolIndex。即TCI field的同一个codepoint对应的独立的下行TCI state和独立的上行TCI state对应的CORESETPoolIndex可以独立配置。当不同RRH对应不同CORESETPoolIndex时，即TCI field的同一个codepoint对应的多个TCI state可以配置为不同的RRH标识，也可以配置为相同的RRH标识。
可选的，在TCI field的同一个codepoint对应多个TCI state的情况下，每个TCI state可以对应一个CORESETPoolIndex，即TCI field的同一个codepoint对应的多个TCI state可以分别对应不同的CORESETPoolIndex。当不同RRH对应不同CORESETPoolIndex时，即TCI field的同一个codepoint对应的多个TCI state可以配置为不同的RRH标识，也可以配置为相同的RRH标识。
其中，多个TCI state可以为多个联合TCI state、或多个独立的上行TCI state，和/或多个独立的下行TCI state等等，本公开对此不做限定。
举例来说，本实施例中，任一个MAC CE激活的控制资源集池索引对应的TCI state，可以如表3所示。
表3

请参见图9，图9是本公开实施例提供的一种传输配置指示状态的确定方法的流程示意图,该方法由网络设备执行。如图9所示，该方法可以包括但不限于如下步骤：
