[0002] In the existing protocol, a valid symbol type for obtaining CSI (Channel State Information Reference Signal) can be configured in CSI-ReportConfig, wherein the CSI reference resource is used to determine the time domain position and / or frequency domain position of the CSI-RS occasion for obtaining CSI.

[0003] In the process of conceiving and implementing the present application, the inventors have found that at least the following problems exist:

[0004] In the SBFD (Subband Full-Duplex) scenario, the existing CSI reference resource associated valid downlink slot does not distinguish the valid symbol type (i.e., does not distinguish the SBFD symbol and the non-SBFD symbol), if the CSI report is configured with different valid symbol types, and if the same CSI reference resource is still used to determine the CSI-RS occasion for obtaining CSI, and the CSI measurement is performed based on the CSI-RS occasion, it will lead to inaccurate CSI measurement.
