Abstract:
1. A method of a mobile station (MS) for uplink (UL) control in a wireless communication system supporting beamforming, the method comprising: receiving a plurality of downlink (DL) reference signals from a plurality of transmission beams corresponding to at least one antenna of a base station (BS) using a plurality of reception beams corresponding to at least one antenna of the MS; measuring a path loss value each of the reference signals based on a reception signal strength of each of the plurality of DL reference signals; selecting at least one transmission beam of the MS for uplink based on the path loss value measured for each of the plurality of DL reference signals; and transmitting at least one UL signal used for selecting at least one reception beam of the BS in the BS, to a BS through the selected at least one transmission beam among transmission beams of the MS.
