Beam direction selection method and apparatus for use in beamforming system

Abstract

A method and apparatus for selecting a beam direction is for use in a beamforming system. The beam direction selection method of a reception device having a plurality of antenna elements in a wireless communication system using beamforming according to the present disclosure includes acquiring a first reception beam angle estimated as optimal by allocating a first predetermined number of antenna elements to each of beam ports and scanning signals and acquiring a second reception beam angle estimated as optimal by allocating a second predetermined number of antenna elements, which is greater than the first predetermined number, to some of the beam ports and scanning the signals using the first reception beam angle. The beam selection apparatus and method of the present disclosure is capable of selecting a reception beam direction efficiently in a beamforming system.
