Abstract: The present specification relates to a method for reporting channel state information (CSI) in a wireless communication system, comprising the steps of: receiving, from a base station, CSI-reference signal (RS) resource configuration information for indicating a resource configuration of a CSI-RS using more than eight antenna ports; receiving, from the base station, a CSI-RS using the more than eight antenna ports based on the received CSI-RS resource configuration information; and reporting, to the base station, channel state information (CSI) based on the received CSI-RS. Therefore, mutual compatibility with a legacy system may be obtained and resources may be more efficiently utilized.
