A method for supporting a vehicle communication (connected car or vehicle to everything (V2X)) service in a wireless communication system and an apparatus thereof are provided. The method includes receiving threshold information for reporting a channel busy ratio (CBR), measuring the CBR for a resource pool, identifying whether a reporting condition is satisfied by comparing the measured CBR with the threshold information, and reporting the measured CBR if the reporting condition is satisfied. The present disclosure relates to a communication technique for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with an Internet of things (IoT) technology, and may be applied to intelligent services based on the 5G communication technology and the IoT-related technology.
