Multiple channel state information reference signal resource indicator report

An apparatus for wireless communications at a base station, comprising:

• a transceiver;
• a memory storing computer-executable instructions;
• and
• a processor coupled with the transceiver and the memory and configured to execute the instructions to cause the apparatus to:
• transmit a configuration of a channel state information (CSI) report to a first user equipment (UE), the configuration including an indication of a sounding reference signal or uplink demodulation reference signal transmitted by a second UE as an interference measurement resource (IMR);
• schedule the second UE to transmit the sounding reference signal or the uplink demodulation reference signal on the IMR;
• and
• receive the CSI report from the first UE, wherein the CSI report includes at least one channel characteristic and the at least one channel characteristic takes into account cross-link interference of the second UE to the first UE, wherein the CSI report comprises information for a plurality of CSI reference signal (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, and wherein the configuration indicates a number of the CRIs to report.

A method of wireless communications at a first user equipment (UE) comprising:

• receiving a configuration of a channel state information (CSI) report, the configuration including an indication of a sounding reference signal or uplink demodulation reference signal transmitted by a second UE as an interference measurement resource (IMR);
• measuring the IMR to determine a cross-link interference of the second UE to the first UE;
• and
• transmitting the CSI report, wherein the CSI report includes at least one channel characteristic, the at least one channel characteristic takes into account the cross-link interference of the second UE, wherein the CSI report comprises information for a plurality of CSI reference signal (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, and wherein the configuration indicates a number of the CRIs to report.
