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.

Abstract: Systems and techniques for transmitting channel state information (CSI) include: receiving configuration information related to the CSI from a base station, the configuration information including information on a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI to the base station based on the configuration information and the CSI-RS. The CSI-RS resource set includes M CSI-RS resource groups; in addition, N CSI-RS resource groups (NMI) for reporting the CSI are determined from the M CSI-RS resource groups; the CSI includes N CSI sets generated based on a CSI-RS resource combination in the N CSI-RS resource groups. To generate an n-th (1≤n≤N) CSI set, a specific CSI-RS resource in an n-th (1≤n≤N) CSI-RS resource group is used for channel measurement; and a specific CSI-RS resource in the remaining CSI-RS groups other than the n-th CSI-RS resource group is used for interference measurement.
