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. ## Claims ### Claim at position 1 1-15. (canceled) ### Claim 16 A method of a user equipment (UE) in a wireless communication system, the method comprising: obtaining an uplink transmission resource; determining whether a medium access control (MAC) protocol data unit (PDU) to be transmitted in the uplink transmission resource is stored in a hybrid automatic repeat request (HARQ) buffer; and identifying a priority of the uplink transmission resource, wherein, in case that the MAC PDU to be transmitted in the uplink transmission resource is stored in the HARQ buffer, the priority of the uplink transmission resource is identified based on a highest priority among priorities of logical channels multiplexed to the MAC PDU, and wherein, in case that the MAC PDU to be transmitted in the uplink transmission resource is not stored in the HARQ buffer, the priority of the uplink transmission resource is identified based on a priority of data available that to be multiplexed to a MAC PDU transmitted via the uplink transmission resource. ### Claim 17 (depends on 16) The method of claim 16, wherein, in case that the uplink transmission is capable of being transmitted in a physical layer and there is no other uplink transmission resource overlapped with the uplink transmission resource whose priority is higher than the priority of the uplink transmission resource, the uplink transmission resource is identified as a prioritized uplink transmission resource. ### Claim 18 (depends on 16) The method of claim 16, wherein, in case that the uplink transmission is capable of being transmitted in a physical layer and new data that uses the uplink transmission resource is obtained, the prioritized uplink transmission resource is identified based on a priority of a logical channel related to the new data. ### Claim 19 (depends on 18) The method of claim 18, wherein, in case that the priority of the logical channel related to the new data is higher than the priority of the uplink transmission resource, the priority of the uplink transmission resource is newly identified based on the priority of the logical channel related to the new data. ### Claim 20 (depends on 17) The method of claim 17, wherein, in case that the uplink transmission is capable of being transmitted in a physical layer and there is another uplink transmission resource overlapped with the uplink transmission resource whose priority is higher than the priority of the uplink transmission resource, the another uplink transmission resource is identified as a prioritized uplink transmission resource. ### Claim 21 (depends on 17) The method of claim 17, wherein the other uplink transmission resource is identified as a deprioritized uplink transmission resource. ### Claim 22 (depends on 16) The method of claim 16, wherein, in case that another uplink transmission resource that overlaps the uplink transmission resource is present, uplink transmission is determined based on the priority of the uplink transmission resource. ### Claim 23 A user equipment (UE) in a wireless communication system, the UE comprising: a transceiver; and a controller configured to: obtain an uplink transmission resource, determine whether a medium access control (MAC) protocol data unit (PDU) to be transmitted in the uplink transmission resource is stored in a hybrid automatic repeat request (HARQ) buffer, and identify a priority of the uplink transmission resource, wherein, in case that the MAC PDU to be transmitted in the uplink transmission resource is stored in the HARQ buffer, the priority of the uplink transmission resource is identified based on a highest priority among priorities of logical channels multiplexed to the MAC PDU, and wherein, in case that the MAC PDU to be transmitted in the uplink transmission resource is not stored in the HARQ buffer, the priority of the uplink transmission resource is identified based on a priority of data available that to be multiplexed to a MAC PDU transmitted via the uplink transmission resource. ### Claim 24 (depends on 23) The UE of claim 23, wherein, in case that the uplink transmission is capable of being transmitted in a physical layer and there is no other uplink transmission resource overlapped with the uplink transmission resource whose priority is higher than the priority of the uplink transmission resource, the uplink transmission resource is identified as a prioritized uplink transmission resource. ### Claim 25 (depends on 23) The UE of claim 23, wherein, in case that the uplink transmission is capable of being transmitted in a physical layer and new data that uses the uplink transmission resource is obtained, the prioritized uplink transmission resource is identified based on a priority of a logical channel related to the new data. ### Claim 26 (depends on 25) The UE of claim 25, wherein, in case that the priority of the logical channel related to the new data is higher than the priority of the uplink transmission resource, the priority of the uplink transmission resource is newly identified based on the priority of the logical channel related to the new data. ### Claim 27 (depends on 23) The UE of claim 23, wherein, in case that the uplink transmission is capable of being transmitted in a physical layer and there is another uplink transmission resource overlapped with the uplink transmission resource whose priority is higher than the priority of the uplink transmission resource, the another uplink transmission resource is identified as a prioritized uplink transmission resource. ### Claim 28 (depends on 24) The UE of claim 24, wherein the other uplink transmission resource is identified as a deprioritized uplink transmission resource. ### Claim 29 (depends on 23) The UE of claim 23, wherein, in case that another uplink transmission resource that overlaps the uplink transmission resource is present, uplink transmission is determined based on the priority of the uplink transmission resource.
