    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.

    Abstract: The present invention relates to a 5th-generation (5G) or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4th-generation (4G) communication system, such as long term evolution (LTE), and subsequent systems. According to the present invention, a method by which a transmission device transmits a reference signal in a communication system supporting a full-dimension multiple input multiple output (FD-MIMO) mode comprises the steps of: transmitting, to a reception device, reference signals through m number of antenna ports; and transmitting, to the reception device, reference signals through n number of antenna ports, wherein the m number of antenna ports have a first polarization characteristic, the n number of antenna ports have a second polarization characteristic, the m number of antenna ports are included in a first axis of a two-dimensional space to be generated on the basis of a vertical axis and a horizontal axis of a uniform planar array (UPA) antenna, and the n number of antenna ports are included in a second axis of the two-dimensional space.

    Abstract: Provided is a method and apparatus for operating a control channel in a beamforming-based wireless communication system. The provided method includes acquiring information indicating a best Base Station (BS) receive beam for Uplink (UL) communication; determining a control channel region for UL control channels in a UL interval considering the best BS receive beam, the control channel region being a predetermined region that is mapped to the best BS receive beam; and exchanging information about the control channel between a BS and a Mobile Station (MS) through the control channel region.
