1. An operation method of an integrated access and backhaul (IAB) node in a communication system, the operation method comprising:
measuring a power difference between a first signal received from a first node and a second signal received from a second node;
controlling a transmit power of each of the first node and the second node based on the power difference;
generating scheduling information for allowing the first node and the second node to simultaneously transmit signals;
transmitting the scheduling information to the first node and the second node; and
receiving signals that the first node and the second node simultaneously transmit according to the scheduling information by using the transmit power.
