Abstract
A method and apparatus configures a beamforming coefficient based on the signal strength information without collecting channel information by adjusting the phase of the antennas through random perturbation. An antenna control method of a base station in a wireless communication system using a beamforming technique includes measuring nreceived signal strength at nphase of at least one receive antenna, measuring (n+1)received signal strength at (n+1)phase shifted randomly from the nphase in one of forward and backward directions, and configuring a beamforming coefficient with the phase at which the received signal strength is greatest through comparison of received signal strengths. The random perturbation-based beamforming method and apparatus of the present disclosure is capable of configuring the beamforming coefficient appropriate for the normal cellular environment using a plurality analog array antenna without channel estimation overhead.
