Summary:Techniques for inter base station handovers are provided for the case where a wireless device is operating in a PDCP packet duplication mode. The handover techniques enable the wireless device to transition from PDCP packet duplication with the source cell to DAPS and to transition back to PDCP packet duplication with the target cell when the handover is complete. In some embodiments, the RLC entities established with the source cell are preserved during the inter base station handover. The handover techniques ensure that QoS requirements for URLLC can be met during the inter base station handover.
