Abstract: A method of transmitting, by a terminal, a phase noise compensation reference signal in a wireless communication system is discussed. The method includes determining a frequency resource and a time resource of a demodulation reference signal (DM-RS); mapping the phase noise compensation reference signal to a frequency resource and a time resource based on the determined frequency resource and the time resource of the DM-RS; and transmitting, to a base station, the phase noise compensation reference signal on the mapped frequency resource and the time resource of the phase compensation reference signal. Further, a location of a phase noise compensation reference signal symbol in the time resource is determined based on a location of a DM-RS symbol in the time resource of the DM-RS.

Abstract: Provided are a method and an apparatus for performing communication based on hybrid beamforming in a wireless communication system. Specifically, a user equipment (UE) transmits a dedicated scheduling request to a base station (BS). The dedicated scheduling request indicates a first scheduling request that is a request to transmit beam state information, multiplexed on an uplink data channel, or a second scheduling request that is a request to allocate a resource for a reference signal for beam refinement information. When the dedicated scheduling request indicates the first scheduling request, the UE receives an uplink grant including a response to the first scheduling request from the BS. The UE feeds the BSI back multiplexed on the uplink data channel to the BS.
