The present disclosure provides a method for receiving, by a terminal, a channel state information-reference signal (CSI-RS) in an unlicensed band. Particularly, the disclosure comprises: receiving CSI-RS resource information for receiving the CSI-RS and information relating to a first bandwidth allocated for the CSI-RS; and receiving the CSI-RS through CSI-RS resources included in at least one second bandwidth among multiple second bandwidths included in the first bandwidth, wherein the at least second bandwidth is determined on the basis of clear channel assessment (CCA) for each of the multiple second bandwidths.
