可以理解的是，图1所示的网络设备与终端的通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access, CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
为了满足移动通信技术的发展，以及对速率的更高要求，提出高频大带宽、大规模天线技术和多载波聚合等技术特征。并且这些技术特征已经成为新一代通信技术的毫米波频段的主要技术特征。
在大规模天线技术中，需要对波束进行管理，保证终端和网络侧设备都能选择到最优的波束，从而保重最好的连接性能。因此，在多载波系统中，尽管终端可以上报支持不同波束管理能力，但是，波束管理信令和多载波系统中载波的数量相同。换言之，终端上报支持统一波束管理或支持独立波束管理，网络侧针对统一波束管理和支持独立波束管理，采用相同信令开销的波束管理方法。
在相关技术中，网络侧设备(例如，基站)采用的波束管理方法是，在每个激活的带宽部分(Bandwidth Part，BWP)上发送波束管理信令。在多载波系统中，如果终端上报支持统一波束管理，基站则基于每个激活载波的BWP上发送包含相同传输配置指示(Transmission Configuration Indication，TCI)的波束管理信令。如果终端上报支持独立波束管理，基站则基于每个激活载波的BWP上发送包含不同TCI的波束管理信令。
如上述实施方式，无论终端上报支持统一波束管理，还是支持独立波束管理，基站都需要下发多个波束管理信令，即，在每个载波的BWP上，均发送包含TCI的波束管理信令，造成了不必要的信令开销。
基于上述技术问题，本公开提供一种波束管理方法，针对支持统一波束管理的载波，发送一个包含传输配置指示TCI的波束管理信令。既可以保证选择较好的波束方向，又可以节省信令开销。
