Abstract
The disclosure is related 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). The disclosure is related to a precoding/beamforming using a massive antenna. A method for operating a base station in a wireless communication system includes transmitting vertical reference signals and horizontal reference signals that are generated based on an interference relation between terminals, receiving long-term channel information determined by using the vertical reference signals and the horizontal reference signals, transmitting group-specific reference signals beamformed by a first beamformer generated based on the long-term channel information, receiving short-term channel information determined by using the group-specific reference signals, and transmitting a data signal beamformed by a second beamformer generated based on the short-term channel information.
