Abstract
A method and apparatus for transmitting an uplink beam scanning signal in a wireless communication system is provided. A terminal first performs downlink beam scanning, and then transmits the uplink beam scanning signal to a base station through a time-frequency resource corresponding to a beam selected according to the downlink beam scanning. The terminal may transmit information on the downlink beam scanning to the base station. The base station may divide a plurality of terminals into a plurality of groups on the basis of information on downlink beam scanning, received from the plurality of terminals, and perform uplink beam scanning for only uplink beams which are selected corresponding to the plurality of groups among all the uplink beams.
