    Abstract: Provided are a method and device for transmitting and receiving data in a wireless communication system, and an operation method of a terminal in a wireless communication system may include, in case that transmission of a scheduling request (SR) is pending and logical channel-based prioritization is configured for a medium access control (MAC) entity of the terminal, identifying whether a physical uplink control channel (PUCCH) resource associated with transmission of the SR overlaps with a physical uplink shared channel (PUSCH) resource associated with transmission of a message A in a time domain, in case that the PUCCH resource associated with the transmission of the SR does not overlap with the PUSCH resource associated with the transmission of the message A, identifying whether the PUCCH resource associated with the transmission of the SR overlaps with a PUSCH resource associated with uplink data in the time domain, and in case that the PUCCH resource associated with the transmission of the SR overlaps with the PUSCH resource associated with the uplink data, transmitting the SR or the uplink data to a base station by comparing a priority of the PUCCH resource associated with the transmission of the SR with a priority of the PUSCH resource associated with the uplink data.

    Abstract: The present disclosure relates to a communication technique for merging 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, healthcare, digital education, retail, 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 performed by a terminal in a wireless communication system and an apparatus for performing same, the method comprising the steps of obtaining an uplink transmission resource, determining whether a medium access control (MCA) protocol data unit (PDU), which is to be transmitted as the uplink transmission resource, is stored in a hybrid automatic repeat request (HARQ) buffer, and identifying the priority of the uplink transmission resource on the basis of a result of the determination.

    Abstract: The disclosure relates to a pre-5th generation (5G) or 5G communication system for supporting higher data rates beyond a 4th generation (4G) communication system such as long term evolution (LTE). A method performed by a network entity for handling a multicast and broadcast service (MBS) in a 5G communication network is provided that includes receiving a request for receiving at least one multicast service from a user equipment (UE), which includes at least one of a session join request or a service request, configuring the at least one multicast service based on the request, and sending the at least one multicast service to the UE over a radio resource control (RRC) reconfiguration message, which includes at least one of a point-to-multipoint (PTM) bearer configuration for a point-to-point (PTM) mode, a PTP bearer configuration for a PTP mode, or a split bearer configuration for a split bearer mode.

    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 of operating a terminal in a wireless communication system comprises the steps of: determining a V2X service requiring direct communication and selecting a radio access technology resource according to the V2X service; when it is determined that a terminal is located within the coverage of a base station, transmitting V2X service information to the base station and receiving, from the base station, radio access technology resource setting information according to the V2X service; when it is determined that the terminal belongs to a specific V2X service group, receiving, from a lead terminal of the corresponding service group, the radio access technology resource setting information according to the V2X service of the group; when it is determined that a cast session with another terminal is established for the specific V2X service, receiving the radio access technology resource setting information according to a V2X service to be used in the unicast session; and transmitting and receiving a V2X service packet by using the set radio access technology resource.
