Method and apparatus for measuring and reporting cross-link interference in next-generation mobile communication system

A user equipment (UE) measuring and reporting cross link interference (CLI) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• at least one processor configured to:
• receive, from a base station (BS), measurement configuration information including a measurement object for CLI measurement;
• perform measurement on one or more resources indicated by the measurement object for CLI measurement;
• and
• in case that a measurement result of at least one resource from the one or more resources indicated by the measurement object for CLI measurement fulfills a measurement report condition, control the transceiver to transmit, to the BS, a measurement report for the at least one resource of which the measurement result fulfills the measurement report condition, from among the one or more resources indicated by the measurement object for CLI measurement.
