    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. The present disclosure relates to a method and apparatus for transmitting uplink (UL) data in a wireless communication system. A method includes receiving configuration information for a grant-free UL transmission, the configuration information including information on a number of repetitive transmissions and period information; identifying resources for repetitive transmissions in a period based on the configuration information; identifying a resource for an initial transmission of the UL data based on a value of a redundancy version (RV) associated with the resource, wherein the resource for the initial transmission of the UL data is associated with an RV value 0; and performing the initial transmission of the UL data on the identified resource.

    Abstract: A method, performed by a base station, of transmitting and receiving data in a wireless communication system, and an apparatus therefor are provided. The method includes determining whether a code block (CB), one of a plurality of CBs included in a transport block (TB), is scheduled for a transmission based on code block group transmission information (CBGTI), in response to the CB being scheduled for the transmission, determining a length of a sequence for the CB based on a number of CBs of the TB or a number of scheduled CBs of the TB, generating the sequence for the CB according to the determined length of the sequence, and transmitting a signal including the generated sequence.

    Abstract: The present invention relates to a communication technique, which is a convergence of IoT technology and 5G communication system for supporting higher data transmission rate beyond 4G system, and a system for same. The present invention can be applied to smart services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security- and safety-related services and the like) on the basis of 5G communication technology and IoT-related technology. The present invention provides a resource allocation method by a base station comprising the steps of: comparing a transmission time interval (TTI), which is for transmitting data to a terminal, with a preconfigured transmission time interval reference value; if the transmission time interval for the data transmission is shorter than the transmission time interval reference value, determining a resource allocation type for showing frequency resources allocated for the data transmission, and generating control information on the basis of the determined resource allocation type.

    Abstract: The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT. A method of a base station includes determining a contention window for a sub-band among multiple sub-bands based on hybrid automatic repeat request-acknowledgement feedbacks corresponding to physical downlink shared channels (PDSCHs) in a reference duration, identifying a number for the sub-band between zero and the contention window, sensing the sub-band based on the number and a defer duration, and performing a downlink transmission based on sensing the sub-band to be idle, wherein the reference duration starts from a beginning of a channel occupancy and ends at a first slot where at least one of the PDSCHs is transmitted, and wherein the PDSCHs in the reference duration include a PDSCH that partially but not fully overlaps with the sub-band among the multiple sub-bands and a PDSCH that fully overlaps with the sub-band among the multiple sub-bands.
