Abstract: Methods and apparatuses are provided in which a radio resource control (RRC) message is transmitted to a terminal. A set of values for an offset between a transmission time interval (TTI) with a downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) to a TTI where the PUSCH is transmitted is included in the RRC message. First DCI scheduling a first PUSCH is transmitted to the terminal. A number of bits associated with one value in the set of values is included in the first DCI. Uplink data on the PUSCH is received from the terminal, in a TTI determined by using the RRC message and the number of bits in the DCI.

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). The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. The method of a terminal in a wireless communication system are provided. The method includes receiving information, which is related to a first transmission time and a second transmission time of an uplink signal of a terminal, from a base station, when the uplink signal of the terminal is configured in an unlicensed band, performing a channel access in the unlicensed band, and when the unlicensed band is not in an idle state based on a channel access result before the first transmission time, performing a channel access until the second transmission time.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system with a technology for Internet of Things (IoT). Methods and apparatuses are provided in which first sidelink data and second sidelink data are received from one or more terminals. It is determined whether a first resource for transmitting first feedback information for the first sidelink data and a second resource for transmitting second feedback information for the second sidelink data overlap each other. When the first resource and the second resource overlap each other, feedback information corresponding to one of the first feedback information and the second feedback information having a higher priority, is transmitted to the one or more terminals. A priority of each of the first feedback information and the second feedback information is based on sidelink control information scheduling each of the first sidelink data and the second sidelink data.
