Claim 0:
1. An operation method of a repeater relaying wireless communications between a base station and a terminal in a communication system, the operation method comprising:
requesting, from the base station, permission to reuse radio resources allocated to one or more beams of a plurality of beams of the base station for beamforming for a link between the repeater and the terminal;
receiving, from the base station, a signal permitting to reuse radio resources allocated to one or more beams of the plurality of beams of the base station;
obtaining reuse preference information for the plurality of beams of the base station, which is determined based on a signaling signal transmission and reception operation with the base station;
receiving, from the base station, a first signal to be transmitted to the terminal;
transmitting, to the terminal, the first signal by using a first radio resource used for transmission of the first signal; and
transmitting, to the terminal, the first signal by using a second radio resource selected based on the determined reuse preference information,
wherein the obtaining of the reuse preference information comprises:
determining reuse preference for each of the plurality of beams of the base station; and
transmitting, to the base station, the reuse preference information including information on the determined reuse preference for each of the plurality of beams through a first signaling signal.
