Since the channel conditions corresponding to different panels are different, different panels need to adopt different transmission parameters according to their respective channel information. In order to obtain these transmission parameters, it is necessary to configure different Sounding Reference Signal Resources (SRS Resources) for different panels to obtain uplink channel information.
