1. A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive reference symbols;
measure a first received power of the reference symbols on a first antenna port;
measure a second received power of the reference symbols on a second antenna port that is coupled to and uses a same transmit power amplifier as the first antenna port;
determine a received power difference based on a relationship between the second received power and the first received power; and
transmit a value of the received power difference, wherein a transmit power relaxation for the second antenna port relative to the first antenna port is based on a relationship between the received power difference and a base station received power difference.
