Abstract: Aspects directed towards Quality of Service (QoS) flow remapping are disclosed. In an example, upon detecting a mapping reconfiguration of a first QoS flow from a first data radio bearer (DRB) to another DRB, a Service Data Adaptation Protocol (SDAP) control protocol data unit (PDU) is generated indicating that a final SDAP data PDU associated with the first QoS flow has been transmitted on the first DRB. The SDAP control PDU is then transmitted via the first DRB. In another example, upon detecting a mapping reconfiguration of a first QoS flow from a first DRB to another DRB, an end marker parameter is set in an SDAP header of a first SDAP data PDU received from an upper layer after the mapping reconfiguration indicating that the first SDAP data PDU is a final SDAP data PDU associated with the first QoS flow transmitted on the first DRB.
