Method and apparatus for adjusting maximum uplink transmission power in wireless communication system

A base station in a communication system, the base station comprising:

• a transceiver;
• and
• a controller operably coupled to the transceiver, the controller configured to:
• identify a number of power management maximum power reduction (P-MPR) values configured to be reported for a serving cell, wherein the P-MPR values are associated with maximum output power of a user equipment (UE) and the P-MPR values are applied to meet a maximum permissible exposure (MPE) requirement;
• and
• receive, from the UE, a report including one or more P-MPR values for the serving cell,
• wherein the report includes a plurality of P-MPR values for the serving cell in case that the plurality of P-MPR values is configured to be reported for the serving cell.

A method performed by a user equipment (UE) in a communication system, the method comprising:

• identifying a number of power management maximum power reduction (P-MPR) values to be reported for a serving cell, wherein the P-MPR values are associated with maximum output power of the UE and the P-MPR values are applied to meet a maximum permissible exposure (MPE) requirement;
• and
• transmitting, to a base station, a report including one or more P-MPR values,
• wherein the report includes a plurality of P-MPR values for the serving cell in case that the plurality of P-MPR values is configured to be reported for the serving cell.
