    Abstract: The present 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 present 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.A base station and a terminal that perform communication using an unlicensed band may divide a bandwidth part into a plurality of subbands and may perform a channel access procedure for the respective subbands. A method for configuring a size of the subband and a method for configuring start/end frequency locations of the configured subband in order to perform the channel access procedure more efficiently in a communication system having various bandwidth sizes and subcarrier spacings. Further, according to the disclosure, a method by a terminal in a wireless communication system includes receiving configuration information of a bandwidth part from a base station; receiving subband configuration information from the base station; receiving control information including a result of a channel access procedure performed for each subband and resource allocation information; and receiving data based on the result of the channel access procedure and the resource allocation information.

    Abstract: 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) are provided. The system and method provides for receiving, from a base station, downlink control information (DCI) including information on a hybrid automatic repeat request (HARQ) process number, identifying at least one grant free resource corresponding to the information on the HARQ process number, and releasing the at least one grant free resource based on the information. The disclosure discloses a grant-free based data transmission method in a wireless communication system that 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.
