Prioritization and timing for cross-link interference reporting
Methods, systems, and devices for wireless communications are described. In one aspect, a UE may report channel state feedback (CSF) to a network entity based on channel state information (CSI) measurements and CLI measurements. In another aspect, a UE may explicitly report CLI measurements to a network entity. In yet another aspect, a UE may report a signal-to-interference-plus-noise ratio (SINR) to a network entity based on CLI measurements, and the network entity may trigger the UE to perform further CLI measurements on signals received from other UEs based on the SINR. In yet another aspect, a UE may generate a report using CLI measurements based on whether the UE is allocated enough time to generate and transmit the report. In yet another aspect, a UE may identify a suitable priority for reporting CLI to a network entity.
