The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method of operating a first Radio Unit (RU) for transmitting an uplink signal in a communication system of the present disclosure includes receiving a first signal through an antenna, re-compensating a second signal delivered from a second RU through a transmission line by using a re-compensation factor, compensating a third signal obtained by adding the first signal and the re-compensated second signal by using a compensation factor, and delivering the compensated third signal to a higher-level RU or a Digital Unit (DU).
