COMMUNICATION METHOD AND DEVICE USING BEAMFORMING IN WIRELESS COMMUNICATION SYSTEM

Samsung Electronics Co., ...

1. A method for transmitting a signal using beamforming by a base station in a wireless communication system, the method comprising:determining to enable a beam superposition based on a first trigger condition that a standard deviation of receive signal strength measurements for at least one unitary beam reported by a mobile station exceeds a beam superposition allocation threshold, the at least one unitary beam being at least one among a plurality of unitary beams corresponding to an array antenna of the base station;
determining a number of unitary beams to be superposed and selecting the determined number of unitary beams from among the plurality of unitary beams based on at least one predetermined condition related to the beam superposition and channel quality information received from the mobile station, the channel quality information including information about a channel quality measured by the mobile station for a combination of the selected unitary beams;
configuring the array antenna of the base station to form a superposed beam by superposing the selected unitary beams;
performing a communication with the mobile station through the superposed beam;
determining to disable the beam superposition based on a second trigger condition that a standard deviation of receive signal strength measurements for the superposed beam reported by the mobile station exceeds a beam superposition release threshold; and
performing the communication with the mobile station through one or more unitary beams among the plurality of unitary beams,
wherein the combination of the selected unitary beams is determined based on beam information transmitted from the base station to the mobile station, and the beam information includes information about a maximum number of unitary beams available to form the superposed beam.
