High order digital post-distortion procedures

A method for wireless communications at a base station, comprising:

• selecting a power amplifier model associated with downlink signaling according to a first set of parameters associated with the power amplifier model;
• transmitting, to a user equipment (UE), the first set of parameters and a second set of parameters corresponding to a non-linear equalizer function;
• transmitting, to the UE, signaling comprising information associating a set of indices with respective parameters corresponding to the power amplifier model, parameters corresponding to a non-linear equalizer function, or both;
• and
• transmitting, to the UE, a downlink signal according to the first set of parameters associated with the power amplifier model.

An apparatus for wireless communications at a user equipment (UE), comprising:

• memory;
• and
• one or more processors coupled with the memory and configured to cause the apparatus to:
• receive, 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;
• perform 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;
• remove a distortion element associated with the downlink signal based at least in part on the digital post-distortion procedure;
• and
• decode the downlink signal subsequent to removing the distortion element associated with the downlink signal.
