1. A method of wireless communication performed by a user equipment (UE), the method comprising:
detecting an error when decoding a data transmission received from a base station (BS) via a bandwidth part (BWP);
transmitting, to the BS in response to detecting the error, a feedback signal associated with the data transmission; and
transmitting, to the BS in response to the transmitting the feedback signal, a first sounding resource signal (SRS) using a first aperiodic SRS resource set of the BWP, wherein the first SRS aperiodic resource set is configured for an antenna switching operation, and wherein a transmit power of the first SRS is configured to exceed a transmit power of a second SRS of the antenna switching operation configured to be transmitted using the first aperiodic SRS resource set.
