Abstract (en)

[origin: WO2020033636A1] Systems and method provide for protocol data unit (PDU) forwarding. A gNB-CU-CP of a target gNB, processes a proposal to forward one or more DL QoS flows from a source gNB to the target gNB. The gNB-CU-CP determines which of the QoS flows to accept or reject for forwarding and generates an indication for a gNB-CU-UP of accepted QoS flows for forwarding. The gNB-CU-CP may propagate per QoS flow DL forwarding proposal and the gNB-CU-UP may decide to accept or not when admitting. Based on the list of accepted QoS flows, the gNB-CU-UP handles new packets from a UE before receiving an end marker forwarded, wherein the new packets correspond to one or more QoS flows that are different than the accepted QoS flows.
