Abstract:
Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.
