1. A user equipment (UE) comprising:
a transceiver configured to:
transmit, to a base station (BS), UE capability information that indicates support for adjusted symbol constellations, wherein the adjusted symbol constellations are adjusted to pre-compensate for distortion effects of a power amplifier (PA) in the transceiver, and
receive, from the BS, a modulation and coding scheme (MCS) indication; and
a processor operably coupled to the transceiver and configured to:
determine, based on the MCS indication, an adjusted symbol constellation, and
generate modulation symbols from input bits according to the determined adjusted symbol constellation,
wherein the transceiver is further configured to transmit, to the BS, the modulation symbols.
