Abstract: The present disclosure relates to 5th generation (5G) or pre-5G communication systems supporting higher data transmission rates than 4th generation communication systems (e.g., Long-Term Evolution). A method to be performed by a repeater device includes receiving, from a base station in the wireless communication system, control information including configuration information indicating a repeater index list, receiving, from the base station, a downlink signal, identifying whether an index of the downlink signal is included in the repeater index list, based on identifying that the index of the downlink signal is included in the repeater index list, amplifying the downlink signal, and transmitting a repeater beamforming signal that is generated by applying a beamforming weight to the amplified downlink signal, and, based on identifying that the index of the downlink signal is not included in the repeater index list, amplifying the downlink signal and transmitting the amplified downlink signal.
