Title:
PDCP DUPLICATION CONFIGURATION OVER E1
Document Type and Number:
WIPO Patent Application WO/2019/139530
Kind Code:
A1
Abstract:
A network node (500, 600) comprising a control plane, CP, circuit (610), a user plane, UP,circuit (620), and at least one distribution unit, DU, circuit (630) provides packet duplication. The CP circuit (610) operatively connects to the at least one DU circuit (630) via a control plane interface, and the CP circuit (610) operatively connects to the UP circuit (620) via a control unit interface. The network node (500, 600) is operative to communicate with a wireless device (10). The CP circuit (610) sends a duplication signal to the UP circuit (620) via the control unit interface to indicate packet duplication per data radio bearer. Further, the UP circuit (620) is configured for the packet duplication responsive to the duplication signal by the configuration of separate first and second bearer tunnels between the UP circuit (620) and the at least one DU circuit (630) responsive to the duplication signal.
