The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure provides a method for performing dynamic cross-link interference (CLI) measurement and reporting in a mobile communication system. In accordance with an aspect of the disclosure, the method performed by a terminal comprises: receiving, from a base station, first information for a measurement object associated with a CLI and second information for a report configuration, the first information including at least one of configuration for sounding reference signal (SRS) resources and configuration for resources to measure a received signal strength indicator (RSSI) associated with the CLI; obtaining a reference signal received power (RSRP) of at least one SRS based on the SRS resources and at least one bandwidth part (BWP) identifier (ID) included in the configuration for the SRS resources; and transmitting, to the base station, a measurement report including the RSRP based on the second information.
