1. An apparatus for wireless communication, comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
determine a power amplifier operating mode associated with non-linear distortion of an input waveform for a power amplifier, wherein the power amplifier operating mode is from a set of two or more power amplifier operating modes each associated with respective amounts of the non-linear distortion;
transmit a set of reference signals associated with estimation of a wireless channel for a transmission; and
transmit an additional set of reference signals associated with non-linear distortion mitigation for the transmission, wherein a resource density of the additional set of reference signals is based at least in part on the power amplifier operating mode.
