Abstract
A method and a device for transmitting/receiving a CSI-RS in a wireless communication system are disclosed. A method for receiving an aperiodic channel state information-reference signal (CSI-RS), according to one embodiment of the present disclosure, may comprise steps of: receiving, from a base station, downlink control information (DCI) for triggering the aperiodic CSI-RS; and receiving, from the base station, the aperiodic CSI-RS on the basis of the DCI, wherein, on the basis the scheduling offset of the aperiodic CSI-RS being smaller than the beam switch timing of a terminal, a quasi co-location (QCL) assumption of a downlink signal associated with the same CORESET pool index as the CORESET pool index of a control resource set (CORESET) for the DCI can be applied for the reception of the aperiodic CSI-RS.
