US 2023/0057791 A1 · METHOD AND APPARATUS FOR DETERMINING PRIORITY VALUE OF RADIO RESOURCE IN WIRELESS COMMUNICATION SYSTEM

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.

1-15. (canceled)

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.
