1. An operation method of a repeater relaying wireless communications between a base station and at least one terminal in a communication system, the operation method comprising:
transmitting a capability report message, to the base station, the capability report message including first information indicating a number of beams supportable by the repeater on a first link between the base station and the repeater, the capability report message further including second information indicating a time required for application of a beam indicated by beam indication information of the base station;
in response to the first information indicating that the number of beams supportable by the repeater on the first link is one, receiving, from the base station, configuration information of one beam on the first link;
in response to the first information indicating that the number of beams supportable by the repeater on the first link is two or more, receiving, from the base station, configuration information of one or more beams on the first link;
performing communication with the base station using the one beam or the one or more beams, based on the first information, to relay the wireless communications on a second link between the base station and the at least one terminal;
receiving the beam indication information from the base station; and
applying the beam indicated by the beam indication information on the second link between the repeater and the at least one terminal, after the time elapses from a reference slot.
