Method and apparatus for measuring and reporting beams in a beamforming based system
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). Disclosed is a method of reporting beam measurement state information by a User Equipment (UE). The method may include: measuring beam state information by using a first reception chain and a second reception chain; controlling beam state information on the first reception chain to correspond to beam state information on the second reception chain; calculating state information on each beam based on the controlled beam state information on the first reception chain and beam state information on the second reception chain; and reporting state information on one or more beams.
