31 Claims

1. A method for wireless communications at a user equipment (UE), comprising:

receiving, from a base station, a first set of parameters corresponding to a power amplifier model associated with downlink signaling and a second set of parameters corresponding to a non-linear equalizer function;

receiving, from the base station, signaling comprising information associating a set of indices with respective parameters corresponding to the power amplifier model, respective parameters corresponding to the non-linear equalizer function, or both;

performing a digital post-distortion procedure on a downlink signal based at least in part on the first set of parameters corresponding to the power amplifier model and the second set of parameters corresponding to the non-linear equalizer function;

removing a distortion element associated with the downlink signal based at least in part on the digital post-distortion procedure; and

decoding the downlink signal subsequent to removing the distortion element associated with the downlink signal.
