1. A method for wireless communication at a user equipment (UE), comprising:
selecting, for transmission of a sounding reference signal, a first set of antennas, wherein the first set of antennas are selected from at least one first antenna of a first antenna group of the UE that is associated with a first exposure constraint and at least one second antenna of a second antenna group of the UE that is associated with a second exposure constraint;
transmitting, to a base station via the first set of antennas, the sounding reference signal over one or more carrier frequencies in accordance with a first transmit power;
determining energy contributions associated with the sounding reference signal towards the first exposure constraint and the second exposure constraint subsequent to transmitting the sounding reference signal; and
transmitting, to the base station via one or more antennas of the first antenna group, an uplink signal over a physical uplink channel in accordance with a second transmit power that is based at least in part on the energy contributions associated with the sounding reference signal.
