Abstract

A method and device for a User Equipment (UE) for connecting to a network are disclosed. In one embodiment, the UE transmits a first Protocol Data Unit (PDU) of a first set of PDUs from a Quality of Service (QoS) stream to a first Data Radio Bearer (DRB). The UE also receives a message or indication from the network for remapping the QoS stream from the first DRB to a second DRB. Additionally, the UE transmits a second PDU of the first set of PDUs to the first DRB, wherein the second PDU is transmitted to the first DRB after receiving the message or indication.

Description

Method and apparatus for remapping quality of service (QOS) flow with protocol data unit (PDU) set considerations in a wireless communication system Cross-reference regarding related applications This application claims the benefit of U.S. Provisional Application No. 63/535,877 filed on August 31, 2023 and U.S. Provisional Application No. 63/602,550 filed on November 24, 2023, the entire disclosures of these applications are incorporated herein by reference in their entirety. Technology field The present disclosure relates generally to wireless communication networks, and more specifically to a method and apparatus for remapping Quality of Service (QoS) flows using Protocol Data Unit (PDU) set considerations in a wireless communication system. As the demand for high-volume data communication to and from mobile communication devices surges, traditional mobile voice communication networks are evolving into networks that communicate using Internet Protocol (IP) data packets. This IP data packet communication can provide users of mobile communication devices with voice over IP, multimedia, multicast, and on-demand communication services. An exemplary network structure is the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). E-UTRAN systems can provide high data throughput to realize the Internet telephony and multimedia services mentioned above. New wireless technologies for the next generation (e.g., 5G) are currently being discussed by the 3GPP standards organization. Accordingly, changes to the current body of the 3GPP standards are currently being proposed and reviewed to advance and finalize the 3GPP standards. A method and device for a User Equipment (UE) for connecting to a network are disclosed. In one embodiment, the UE transmits a first Protocol Data Unit (PDU) of a first set of PDUs from a Quality of Service (QoS) stream to a first Data Radio Bearer (DRB). The UE also receives a message or indication from the network for remapping the QoS stream from the first DRB to a second DRB. Additionally, the UE transmits a second PDU of the first set of PDUs to the first DRB, wherein the second PDU is transmitted to the first DRB after receiving the message or indication.
