Abstract
The present invention relates to a method and an apparatus for receiving a reference signal by a terminal in a wireless communication system. According to the present invention, from a base station, a terminal receives configuration information of a channel state information (CSI)-RS resource for transmission of a CSI-RS, and receives the CSI-RS on the basis of the configuration information. Further, provided may be a method and an apparatus, in which a terminal configures a beam on the basis of the CSI-RS, wherein the configuration information includes at least one of a first indicator indicating the number of times the CSI-RS is repeatedly transmitted, a first offset value of a first subcarrier to which the CSI-RS resource is mapped, and information indicating the maximum number of times the terminal can perform beam sweeping, and the CSI-RS resource is mapped to subcarriers at a predetermined interval on a frequency axis, and the CSI-RS can be repeatedly transmitted within a specific time interval according to the first indicator.
