Abstract

一种带宽部分指示的配置方法、装置和系统，其中，所述方法包括：网络设备为终端设备配置多传输点(TRP)或多面板(panel)操作相关模式；所述网络设备向终端设备发送配置信息和/或下行控制信息，以便终端设备根据接收到的配置信息和/或根据检测到的多个下行控制信息确定激活的带宽部分。由此，在终端设备被配置为多传输点或多面板操作相关模式的情况下，通过配置信息或下行控制信息来显式或隐式地指示终端设备以哪个带宽部分作为激活的带宽部分，终端设备根据接收到的配置信息和/或下行控制信息可以确定激活的带宽部分，解决了由于多个下行控制信令所指示的带宽部分不同而导致的终端设备无法判断在下一个时间单位切换到哪个带宽部分的技术问题。
