ANTENNA SWITCHING METHOD, TERMINAL DEVICE AND COMMUNICATION DEVICE

WIPO Patent Application WO/2021/163938

A1

Embodiments of the present application relate to an antenna switching method, a terminal device and a communication device. The method comprises: a first terminal device receives a configuration message; the configuration message indicates M sounding reference signal (SRS) resource group sets, each SRS resource group set contains at least one SRS resource group, and M is a positive integer; each SRS resource group set corresponds to a corresponding antenna switching configuration, and the antenna switching configuration supports the first terminal device to have more than four receiving antennas. Embodiments of the present application can achieve antenna switching for a terminal device having many (for example, four or more) receiving antennas.
