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、下行控制信息(downlink control information，DCI)
DCI由物理下行控制信道(physical downlink control channel，PDCCH)承载，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。PDCCH是一种物理信道，用于承载下行调度信息。
2、传输配置指示(transmission configuration indicator，TCI)
TCI用于告知用户接收PDCCH或物理下行共享信道(physical downlink share channel，PDSCH)使用与接收基站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； 或告知所述用户发送物理上行控制信道(physical uplink control channel，PUCCH)/物理上行共享信道(physical uplink share 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或接收信道状态信息参考信号(channel state information reference signal，CSI-RS)的接收beam对应的发送beam。
3、媒体接入控制层控制元素(MAC Control Element，MAC CE)
媒体接入控制层控制元素MAC CE是终端和网络之间交换控制信息的一个途径，顾名思义，它交换的是关于MAC层的控制信息。
4、参考信号(reference signal，RS)
参考信号是NR中重要的组成部分，所述RS包括定位参考信号(positioning reference signal，PRS)、相位参考信号(tracking reference signal，TRS)。所述PRS可以作为定位的参考，所述TRS可以作为相位的参考。
为了更好的理解本申请实施例公开的一种传输配置指示TCI状态配置的方法，下面首先对本申请实施例适用的通信***进行描述。
请参见图1，图1为本申请实施例提供的一种通信***的架构示意图。该通信***可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，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***以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信***。例如：长期演进(long term evolution，LTE)***、第五代(5th generation，5G)移动通信***、5G新空口(new radio，NR)***，或者其他未来的新型移动通信***等。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR***中的下一代基站(next generation NodeB，gNB)、其他未来移动通信***中的基站或无线保真(wireless fidelity，WiFi)***中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是终端侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施 例对终端设备所采用的具体技术和具体设备形态不做限定。
Rel-16中，PDCCH、PDSCH、PUSCH、PUCCH以及各个上下行参考信号等的波束都是独立指示的，且PDCCH和PUCCH使用MAC CE来激活一个波束，而PDSCH和PUSCH是根据DCI信令来指示其各自的波束。目前为了减少信令开销，希望使用统一传输配置指示状态(unified TCI state)。unified TCI state，即一个unified TCI state用于一个集合内的多种信道和/或参考信号对应的波束。unified TCI state目前可能是上行和下行分开指示，即根据独立下行传输配置指示状态(separate DL TCI state)用于下行通信的波束指示和/或独立上行传输配置指示状态(separate UL TCI state)用于上行通信的波束指示。或者上下行联合指示，即利用联合传输配置指示状态(joint TCI state)。所述joint TCI state同时用于上行和下行的波束指示。即基站如果指示一个用于下行separate DL TCI state，那么该TCI state可以用于终端的PDSCH和所有或一部分PDCCH(比如UE dedicated PDCCH)，和/或下行参考信号如CSI-RS，SSB，PRS，TRS中的至少一种；基站如果指示一个用于上行的separate UL TCI state，那么该TCI state可以用于终端的PUSCH和所有/或一部分PUCCH和/或PRACH，和/或上行参考信号如SRS,scheduling request中的至少一种。基站如果指示一个joint TCI state，那么该joint TCI state可以用于终端的上行和下行的信道和/或参考信号。
可以理解的是，本申请实施例描述的通信***是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着***架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的传输配置指示TCI状态配置的方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种传输配置指示TCI状态配置的方法的流程示意图。本公开实施例应用于终端设备。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：接收网络设备发送的配置信息，其中，所述配置信息包括至少一个传输配置指示代码点对应的至少一个传输配置指示状态。
本实施例中，终端设备可以接收网络设备发送的配置信息，网络设备可以向终端设备发送所述配置信息。其中所述配置信息用于指示至少一个传输配置指示代码点(TCI codepoint)中元素对应的传输配置指示，所述传输配置指示包括联合传输配置指示和独立传输配置指示中的至少一项。其中所述独立传输配置指示包含独立上行链路传输配置指示和独立下行链路传输配置指示中的至少一项。
步骤S202：根据所述传输配置指示代码点获取通信传输对应的传输配置指示状态。
本实施例中，终端预先配置有传输配置指示TCI状态池，基于所述传输配置指示代码点，即可根据代码点获取通信传输对应的传输配置指示状态(TCI state)。其中，所述TCI state为所述TCI状态池中的一个TCI state。
通过实施本申请实施例，可以根据网络设备发送的配置信息获取通信传输对应的传输配置指示状态，根据一个配置信息即可获取多个传输配置指示代码点对应的多个传输配置指示状态。通过这种方式，可以节省信令资源，从而有利于避免资源浪费。
接收网络设备发送的配置信息，根据所述传输配置指示代码点获取通信传输对应的传输配置指示状态；所述配置信息还包括：
第一指示信息，所述第一指示信息用于指示所述至少一个传输配置指示代码点中的每个元素均对应联合传输配置指示，或
用于指示所述至少一个传输配置指示代码点中的每个元素均对应独立传输配置指示，其中所述独立传输配置指示包含独立上行链路传输配置指示和独立下行链路传输配置指示中的至少一项。
本实施例中，所述代码点如表1所示，其中所述R为预留比特。所示第一指示信息可以复用该R预留比特，或者引入新的比特。如果终端设备接收到所述第一指示信息，则所述代码点中的所有元素均对应独立传输配置指示，或所述代码点中的所有元素均对应独立传输配置指示。比如第一指示信息的比特显示为“0”表示该MAC CE中激活的所有的TCI代码点对应的TCI都是联合TCI，第一指示信息的比特显示为“1”表示该MAC CE中激活的所有的TCI代码点对应的TCI都是独立TCI；或比如第一指示信息的比特显示为“1”表示该MAC CE中激活的所有的TCI代码点对应的TCI都是联合TCI，第一指示信息的比特显示为“0”表示该MAC CE中激活的所有的TCI代码点对应的TCI都是独立TCI。所述独立传输配置指示包含独立上行链路传输配置指示和独立下行链路传输配置指示中的至少一项。

接收网络设备发送的配置信息，根据所述传输配置指示代码点获取通信传输对应的传输配置指示状态；所述配置信息还包括：
