1. An apparatus for wireless communications at a user equipment (UE), comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
receive, from a network entity, control signaling indicating a demodulation reference signal pattern associated with a set of frequency resources, wherein a plurality of frequency subsets of the set of frequency resources are allocated to respective UEs of a set of frequency-division multiplexed UEs comprising the UE;
transmit a set of power amplifier coefficient values associated with a non-linear impairment compensation function based at least in part on the demodulation reference signal pattern; and
receive downlink signaling based at least in part on the set of power amplifier coefficient values.
