METHOD AND DEVICE FOR SELECTING BEAM IN WIRELESS COMMUNICATION SYSTEM WHICH USES A PLURALITY OF ANTENNAS

摘要

The present invention relates to a method and a device for selecting a beam in a wireless communication system which uses a plurality of antennas such as an array antenna. A method according to one embodiment of the present invention is a method for selecting a transmission beam in a transmission device of a wireless communication device comprising a transmission device having a plurality of transmission array antennas, and a receiving device having receiving array antennas in the same number as the number of transmission array antennas, and the method comprises the steps of: determining antenna pairs by measuring the transmission rate of each of the receiving array antennas of the receiving device, individually for each array antenna; determining the number of transmission array antennas and individual transmission-array-antenna modes so as to transmit data according to the service requirements of data whose transmission is required, when data transmission is required; and transmitting data through the determined transmission array antennas.
