    Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as Long-Term Evolution (LTE). The present disclosure may be applied to intelligent services, such as 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. In addition, an operation method of a terminal in a wireless communication system may comprise the steps of: determining service information required by a V2X application and determining a V2X transmission mode; determining QoS information of a service required by the V2X application; obtaining sidelink radio bearer configuration information corresponding to the QoS information; and, using the obtained sidelink radio bearer configuration information, transmitting and receiving V2X packets by means of a device-to-device communication method.

    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 method includes identifying whether a medium access control (MAC) entity of the terminal is configured with a logical channel (LCH)-based prioritization, identifying whether a first uplink grant is associated with a random access, determining the first uplink grant to be a prioritized uplink grant, and transmitting an uplink signal based on the prioritized uplink grant.

    Abstract: Disclosed are: 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. Disclosed are a method and a terminal for performing same, the method being performed by a terminal in a wireless communication system and comprising the steps of: triggering a buffer status report (BSR); triggering a scheduling request (SR) for the BSR; transmitting a medium access control (MAC) protocol data unit (PDU) including the BSR before the transmission of the SR; and determining whether the triggered SR is cancelled on the basis of information about a logic channel corresponding to the SR and logic channel information about the MAC PDU.

    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 terminal in a communication system is provided. The method includes receiving, from a base station, configuration information on a configured grant for uplink transmission, the configured grant being configured with an autonomous transmission; in case that a previous configured grant for a hybrid automatic repeat request (HARQ) process was not prioritized, a transmission of a first medium access control (MAC) protocol data unit (PDU) obtained for the HARQ process has not been performed, and a size of the first MAC PDU matches a size of a configured grant, identifying that the first MAC PDU has been obtained for the configured grant; and in case that the configured grant is a prioritized uplink grant, delivering the obtained first MAC PDU.
