Provided are a method for operating a device in a wireless communication system, and a device using the method. The method comprises: measuring a plurality of reference beams; selecting at least one beam from among the plurality of reference beams; and communicating with a base station using the at least one selected beam, wherein the plurality of reference beams are beams transmitted according to a first scheme or a second scheme. In the first scheme, N (N is a natural number greater than or equal to two) reference beams are transmitted at a first transmission time, and an offset is applied to the N reference beams at a second transmission time. In the second scheme, 2N reference beams are transmitted, wherein a second frequency interval between adjacent beams of the 2N reference beams is half a first frequency interval between adjacent beams of the N reference beams.
