    Abstract: Disclosed are a method and an apparatus for transmitting and receiving channel state information in a wireless communication system. A method for transmitting channel state information (CSI) according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information related to the CSI from a base station, wherein the configuration information includes 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 on the basis of the configuration information and the CSI-RS. The CSI may include a first CSI set based on a single CSI resource in the CSI-RS resource set and/or a second CSI set based on a CSI-RS resource combination in the CSI-RS resource set, and the number of CSI processing units (CPUs) required for calculation of the second CSI set and the number of CPUs required for calculation of the first CSI set may be individually determined.

    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.

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.
