    摘要： 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.

    摘要： A Base Station (BS) cooperative communication method in a wireless communication system is provided. The BS cooperative communication method includes measuring signal quality of one or more neighboring BSs, comparing a number of downlink beams available for communication between a serving BS and a Mobile Station (MS) with a reference value, determining not to involve the one or more neighboring BSs in BS cooperative communication for the MS when the number of downlink beams is equal to or larger than the reference value, comparing signal measurements of the one or more neighboring BSs with a first threshold when the number of downlink beams is smaller than the reference value, and determining to involve one or more neighboring BSs having a signal measurement value larger than the first threshold in the BS cooperative communication for the MS.

    摘要： A communication method and an apparatus using beamforming in a wireless communication system are provided. The communication method includes determining a candidate user set including one or more Mobile Stations (MSs), for Multiple User-Multiple Input Multiple Output (MU-MIMO) transmission, transmitting beam information indicating best Base Station (BS) transmission beams of the MSs of the candidate user set to the MSs of the candidate user set, receiving Precoding Matrix Index (PMI) information indicating a PMI to be used for baseband precoding from each of the MSs of the candidate user set, the PMI information being determined based on the beam information, and transmitting a signal precoded based on the PMI information to at least one MS.
