Abstract: A method and apparatus perform Uplink (UL) beam tracking in a beamforming-based wireless communication system. A Mobile Station (MS) repeatedly transmits code sequences mapped respectively to MS transmit beams through each MS transmit beam as many times as the number of Base Station (BS) receive beams while sweeping the MS transmit beams. The MS receives, from a BS, transmit beam information indicating at least one best transmit beam selected from the MS transmit beams by the BS, and allocation information used to allocate UL resources for UL feedback. The MS transmits best beam information indicating the at least one best transmit beam and a MS identifier to the BS using the UL resources.
