Abstract: A method of a transmitting terminal may include: setting an initial beam pairing flag indicating that the transmitting terminal transmitting sidelink-synchronization signal blocks (S-SSBs) is not a synchronization reference terminal; transmitting a plurality of S-SSBs including the initial beam pairing flag in a beam sweeping scheme; receiving, from a receiving terminal, information on a preferred beam among a plurality of beams through which the plurality of S-SSBs are transmitted; and transmitting data to the receiving terminal using the preferred beam.

Abstract: An operation method of an IAB node in a communication system may comprise: 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.
