Abstract: Provided are a method and an apparatus for transmitting uplink data based on hybrid beamforming in a wireless communication system. Specifically, a user equipment (UE) receives a first modulation and coding scheme (MCS) determined based on a sounding reference signal from a base station (BS) through an uplink grant. The UE determines an MCS offset based on a variation of an uplink channel when the variation of the uplink channel between a subframe for transmitting the sounding reference signal and a subframe for receiving the uplink grant is a threshold or greater. The UE transmits uplink data to the BS using a second MCS acquired from the first MCS and the MCS offset.
