1. A method for wireless communications by a user equipment (UE), comprising:
decoding a sounding reference signal-switching (SRS-switching) report configuration received from a base station;
determining that SRS switching is to be performed by the UE;
based on determining that SRS-switching is to be performed, processing potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching and sounding reference signal-skipping (SRS-skipping) while sharing radio frequency (RF) front-ends (RFFE) between the plurality of RATs, the potential impacts comprising at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the plurality of RATs;
applying the decoded SRS-switching report configuration;
based on applying the decoded SRS-switching report configuration, generating statistics associated with the potential impacts for a given time window; and
encoding, for transmission to the base station, a communication that indicates the potential impacts and that includes an indication of one of a Long Term Evolution (LTE) RAT and Fifth Generation (5G) RAT of the plurality of RATs that will be affected by the potential impacts and that comprises the generated statistics.
