1. A method of an integrated access and backhaul (IAB) node in a communication system, the method comprising:
identifying that a transmission of a mobile termination (MT) and a reception of a distributed unit (DU) are performed simultaneously;
identifying a maximum power reduction (MPR) value defined for a case in which the transmission of the MT and the reception of the DU are performed simultaneously, wherein the MPR value is defined so that a maximum power for the transmission of the MT is smaller than a predetermined maximum power for a backhaul uplink;
calculating the maximum power for the transmission of the MT as a function of the MPR value;
determining a power for the transmission of the MT based on the maximum power; and
transmitting a signal based on the determined power.
