The present disclosure relates to a communication method and system for converging a 5th-Generat ion (5G) communication system for supporting higher data rates beyond a 4th-Generat ion (4G) system with a technology for Internet of Things (IoT). The present disclosure maybe 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 method comprises receiving periodic CSI feedback configuration information including a periodicity value and an offset value corresponding to a first CSI report, and at least one periodicity value and at least one offset value corresponding to a second CSI report.
