Abstract
The present invention relates to a wireless communication system and, more specifically, to a method and an apparatus for reporting channel state information (CSI). Particularly, the method comprises the steps of: receiving a reference signal (RS) from a base station; and reporting, to the base station, the CSI generated by using the RS, wherein the CSI is measured on the basis of a specific CSI-RS set among a plurality of CSI-RS sets, beamforming weight vectors in a vertical domain which are set differently for each of horizontal domain antenna ports to which the same beamforming weight vectors in a vertical domain is applied.
