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.
