1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the processor to:
detect a power exposure event for a user equipment;
send, to a base station, a message including information indicating that the detected power exposure event for the user equipment is a trigger for the sending of the message, and information identifying: a reduced maximum output power value for the user equipment and a reduced maximum uplink duty cycle for the user equipment, based on the detected power exposure event;
detect an end of the power exposure event for the user equipment;
send, to the base station, a message indicating the end of the power exposure event for the user equipment;
send, using a full maximum output power of the user equipment that is greater than the reduced maximum output power, a random access procedure (RACH) message including information indicating that the detected power exposure event for the user equipment is a trigger for the sending of the RACH message, and information identifying: a reduced maximum output power value for the user equipment and a reduced maximum uplink duty cycle for the user equipment, based on the detected power exposure event; and
perform one or more retransmissions of the RACH message using the full maximum output power of the user equipment if an acknowledgement to the RACH message is not received by the user equipment, wherein the performing the one or more retransmissions of the RACH message being performed at a time or with a time backoff that is in accordance with the reduced maximum uplink duty cycle for the user equipment.
