Abstract: Disclosed is a method by which a terminal transmits channel status information (CSI) feedback in a wireless communication system. Particularly, the method for transmitting CSI feedback comprises the steps of: setting, through an upper layer signal, one CSI process having a periodic reference signal and an aperiodic reference signal; receiving, from a base station, an aperiodic CSI feedback request message related to the one CSI process; generating, in response to the aperiodic CSI feedback request message, aperiodic CSI feedback on the basis of the aperiodic reference signal; and transmitting the aperiodic CSI feedback to the base station.
