A user equipment obtains a first channel state information (CSI)-related quantity and a second CSI-related quantity in at least one of: respective first and second CSI-interference measurement (CSI-IM) resources, or respective first and second CSI-reference signal (CSI-RS) resources in respective first and second slots, and transmits a baseline CSI report based on the first CSI-related quantity in the first slot, and a differential CSI report based on the second CSI-related quantity in the second slot, the baseline CSI report being linked to the differential CSI report. In one example, the first slot is a half-duplex slot, the baseline CSI report is a baseline half-duplex CSI report, the second slot is a full-duplex slot, and the differential CSI report is a differential full-duplex CSI report.
