    Abstract: A communication technique for fusing 5G communication, which supports a higher data transmission rate than a 4G system, with an IoT technology is provided, and may be applied to an intelligent service based on the 5G communication technology and the IoT related technology. Accordingly, a method performed by a UE in a communication system includes receiving, from a base station, information indicating a channel access type via DCI, wherein the information indicates the channel access type as one of a first type to sense a channel to be idle before a UL transmission using a random time duration, a second type to sense the channel to be idle before the UL transmission using a deterministic time duration, or a third type not to sense the channel before the UL transmission; and transmitting, to the base station, the UL transmission according to the channel access type.

    Abstract: The present disclosure relates to a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety related services, and the like) on the basis of 5G communication technology and IoT-related technology. The present invention provides a method for constituting the corresponding information, in a situation that a specific type service influences (interference in a wireless communication environment) on other types of services or the same type of service, into control information so as to transfer the control information from a base station to a terminal. The terminal receives the information through a control channel and can adapt a data reception method by utilizing the same.

    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 method performed by a first terminal in a communication system is provided. The method includes transmitting data of a physical side link shared channel (PSSCH) and sidelink control information (SCI) associated with the data, and receiving, from a second terminal, a hybrid automatic repeat request (HARQ) feedback for the data, wherein the HARQ feedback is performed based on a distance between the first terminal and the second terminal, in case that the SCI includes location information of the first terminal.

    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 cell selection/re-selection method and an apparatus adapted thereto is provided. The cell selection method of a terminal includes: receiving, from a base station, first maximum power information, PEMAX1 and second maximum power information, PEMAX2, related to maximum transmission power levels of the terminal on the uplink; calculating a compensation parameter, Pcompensation, related to uplink transmission power of the terminal, using the first maximum power information and the second maximum power information; calculating a cell selection reception level value, Srxlev, using the compensation parameter; and selecting a cell based on the calculated cell selection reception level value.
