1. An apparatus for wireless communication at a user equipment (UE), comprising:
memory; and
at least one processor coupled to the memory and configured to:
receive a federated learning (FL) model from a base station for participation in an FL procedure with the base station;
update the FL model for an iteration of the FL procedure, the update based on whether an uplink transmission would cause a maximum permissible exposure (MPE) threshold to be exceeded, the uplink transmission having a transmit (Tx) power level that corresponds to a configured receive (Rx) power level at the base station; and
drop the uplink transmission if the uplink transmission would cause the MPE threshold to be exceeded.
