Abstract: A pre-5th-generation (5G) or 5G communication system for supporting higher data rates beyond 4th-generation (4G) communication system, such as a long term evolution (LTE), is provided. A method for performing a beamforming operation in a communication system supporting a frequency division-multiple input multiple output (FD-MIMO) scheme is provided. The method includes detecting a rough beam of a first dominant beam, detecting at least two codeword candidates based on the rough beam of the first dominant beam, and selecting one of the at least two codeword candidates as a final codeword.
