Abstract: 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.

Abstract: A method and apparatus for transmitting signals on a PUSCH in a wireless communication system are provided. Specifically, a method performed by a terminal includes receiving resource information for transmitting uplink data and channel state information (CSI) on a PUSCH from a base station; receiving first downlink control information (DCI) including control information on slot timing related to the uplink data transmission from the base station; comparing a first time related to computation of the uplink data and CSI and a second time related to computation of only the CSI; and transmitting, if a value of the slot timing is greater than the second time and smaller than the first time, only the CSI on the PUSCH to the base station.
