    摘要: The present disclosure relates to a method of a terminal in a wireless communication system. The method may include: determining a plurality of temporally sequential uplink transmission resources to repeatedly transmit a transmission block through configured grant-based uplink transmission; identifying a first uplink transmission resource corresponding to first initial transmission for the transmission block from among the determined plurality of uplink transmission resources; when the first initial transmission is cancelled, identifying a second uplink transmission resource corresponding to second initial transmission for the transmission block based on uplink transmission resource candidates following the identified first uplink transmission resource from among the plurality of uplink transmission resources; and performing the second initial transmission through the identified second uplink transmission resource.

    摘要: 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.

    摘要: The present disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (for example, 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 technologies and IoT-related technologies. The present disclosure relates to a method of a terminal in a communication system, the method comprising the steps of: receiving carrier aggregation configuration information from a base station; receiving offset information for a frame boundary between a first cell and a second cell from the base station; receiving, from the base station, control information including time domain resource allocation information indicating an interval between a slot in which data scheduled by the control information transmitted or received and a slot in which the control information is received into the first cell; identifying an index of the slot in which the data is transmitted or received, on the basis of the offset information and the time domain resource allocation information; and transmitting the data to or receiving the data from the base station on the second cell in the slot of the identified index.

    摘要: 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 method performed by a first terminal in a wireless communication system is provided. The method includes identifying configuration information related to sidelink communication, determining first information related to a physical sidelink shared channel (PSSCH) demodulation reference signal (DMRS) for a second terminal based on the configuration information, and transmitting, to the second terminal, sidelink control information (SCI) including the first information.
