Abstract
The present invention relates to a method and an apparatus for performing beam management by a terminal in a wireless communication system. The present invention may provide a method and an apparatus in which a terminal receives, from a base station, configuration information of channel state information (CSI)-RS, and receives the CSI-RS on the basis of the configuration information, wherein the CSI-RS is transmitted through a plurality of antenna ports, and the terminal configures a beam of each of the plurality of antenna ports on the basis of the CSI-RS, wherein the CSI-RS is mapped to subcarriers on a frequency axis at an interval of predetermined number of resource elements (REs), and the CSI-RS is repeatedly transmitted according to the interval of the predetermined number of REs within a specific time period.
