Abstract: A method for operating a user equipment in a wireless communication is provided as an embodiment of the present invention. The method may include: receiving modulation and coding scheme (MCS) information for each of two or more codewords from a base station (BS); determining a demodulation reference signal (DMRS) antenna port to which a phase tracking reference signal (PTRS) antenna port is mapped based on the MCS information; and receiving a PTRS based on the DMRS antenna port, wherein a DMRS antenna port with the lowest index among one or more DMRS antenna ports included in a codeword with the highest MCS among the two or more codewords may be determined as the DMRS antenna port.

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.
