1. An apparatus for wireless communications at a user equipment (UE), comprising:
at least one processor; and
at least one memory coupled with the at least one processor, the at least one memory storing instructions executable by the at least one processor to cause the apparatus to:
identify a time and frequency resource allocated to an uplink shared channel;
identify a threshold signal-to-noise ratio associated with the time and frequency resource; and
transmit both an uplink data signal and a sounding reference signal via at least the time and frequency resource, wherein the uplink data signal and the sounding reference signal overlap in both time and frequency within the time and frequency resource, and wherein the uplink data signal is transmitted using a first transmit power and the sounding reference signal is transmitted using a second transmit power, the first transmit power and the second transmit power based at least in part on the threshold signal-to-noise ratio.
