Adaptive digital post-distortion and modulation and coding scheme index reporting

An apparatus for wireless communications at a network entity, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit an indication of a plurality of digital post-distortion kernels associated with the network entity, each digital post-distortion kernel associated with one or more error vector magnitudes;
• receive an indication of a modulation and coding scheme index in accordance with a digital post-distortion kernel of the plurality of digital post-distortion kernels and a target error vector magnitude;
• and
• transmit a downlink message based at least in part on the modulation and coding scheme index.

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

• receiving an indication of a plurality of digital post-distortion kernels associated with a network entity, each digital post-distortion kernel associated with one or more error vector magnitudes;
• selecting a digital post-distortion kernel of the plurality of digital post-distortion kernels associated with the network entity based at least in part on a target error vector magnitude at the UE;
• transmitting an indication of a modulation and coding scheme index in accordance with the selected digital post-distortion kernel and the target error vector magnitude;
• and
• receiving a downlink message based at least in part on the selected digital post-distortion kernel and the indicated modulation and coding scheme index.
