Abstract: The present specification provides a method for transmitting and receiving a signal by means of a beam in a wireless communication system. Specifically, a method for a terminal for reporting beam-related information in a wireless communication system may comprise the steps of: receiving one or more particular signals for beam management from a base station; and reporting, to the base station, beam information for one or more beams on the basis of result of measurements by means of the one or more particular signals.

Abstract: A method for transmitting a multiplexed uplink control channel and localized sounding reference symbol (localized SRS) by a terminal comprises a step of dividing the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain and then transmitting the divided uplink control channel, when a frequency bandwidth of the localized SRS is smaller than or equal to a coherent bandwidth, wherein the divided uplink control channel sub-blocks may be frequency-division-multiplexed together with at least one localized SRS and then transmitted in one symbol.

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.
