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. In addition, according to the disclosure, a method of a terminal in a wireless communication system comprises the steps of: receiving, from a base station, configuration information including first bandwidth part (BWP) configuration information on a sidelink and information on a resource pool; identifying a resource pool for the sidelink based on the configuration information; and performing communication with another terminal based on the resource pool, wherein the information on the resource pool includes the lowest physical resource block (PRB) index of the resource pool.
