A first user equipment (UE) receives a configuration of a channel state information (CSI) report from a base station. The configuration includes an indication of a sounding reference signal (SRS) or uplink demodulation reference signal (DMRS) transmitted from a second UE as an interference measurement resource (IMR). The base station configures the second UE to transmit the SRS or the uplink DMRS on the IMR. The first UE measures the IMR to determine a cross-link interference of the second UE to the first UE. The UE transmits the CSI report. The CSI report includes at least one channel characteristic that takes into account the cross-link interference of the second UE. The CSI report may include information for a plurality of CSI-RS resource indicators (CRIs), each CRI associated with a same channel measurement resource (CMR) and a different IMR corresponding to a different second UE.
