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.
