1. A user equipment (UE) for wireless communications, comprising:
one or more memories; and
one or more processors coupled with the one or more memories and individually or collectively configured to:
transmit a first message indicating a capability to linearize a digital signal outputted by a receiving analog front end of the UE, the digital signal being associated with a first transmission;
receive the first transmission, the first transmission being associated with a gain state of the receiving analog front end, the gain state comprising a set of configurations associated with a plurality of amplifiers at the UE; and
linearize the digital signal associated with the first transmission based at least in part on the gain state, wherein linearizing the digital signal comprises obtaining an output voltage value corresponding to an input voltage value associated with the receiving analog front end.
