  • MAC-CE ACTIVATION OF CLI REPORTING
    Publication number: 20230328560
    Abstract: A UE may receive a configuration of one or more SP resources for CLI and/or SI measurement, and receive, from the base station, a MAC-CE activating the configured one or more SP resources for CLI and/or SI measurements. The UE may measure the CLI and/or SI based on interference signal and report a CLI report, including the measured CLI and/or SI to the base station. The UE may estimate average CL based on an average transmission power of the interference signal over multiple slots from an aggressor UE, and the base station may use the estimated average CL to determine CLI for aggressor UE based on CLI reciprocity.
