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 (N≤M) 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.

Abstract: Disclosed are a method and device for transmitting and receiving an uplink in a wireless communication system. A method for transmitting a physical uplink control channel (PUCCH) according to an embodiment according to the present disclosure comprises the steps of: receiving configuration information related to a PUCCH from a base station; and transmitting the PUCCH to the base station from one PUCCH resource on the basis of the configuration information. The PUCCH is repeatedly transmitted in a plurality of transmission occasions (TOs) for the one PUCCH resource. The plurality of TOs are mapped to N TO groups (where N is a natural number) each including one or more of the TOs. The N TO groups are associated with N power control parameter sets in the configuration information related to the PUCCH. The transmission power of the PUCCH can be determined on the basis of a power control parameter set associated with the TO group in which the PUCCH is transmitted.
