Abstract: The present invention relates to a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system therefor. In addition, the present invention provides a device for testing a beam forming processor, comprising: at least one power determination unit, which is electrically connected to the beam forming processor for performing beam forming, and determines the output power of the beam forming processor; and a control unit, which is connected to the power determination unit by wire and determines whether the beam forming processor is normal on the basis of the output power received from the power determination unit.

Abstract: 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).
