description Embodiments described herein provide methods and apparatuses for synchronizing radio link control re-establishment between a user equipment (UE) and a base station distributed unit (DU) with Packet Data Convergence Protocol PDCP data recovery. A method performed by a Control Plane data processing apparatus comprises: obtaining an indication that an uplink and/or downlink outage has occurred between the base station DU and the UE; and transmitting a request to a user plane, UP, data processing apparatus to instruct the UP data processing apparatus to retransmit any data protocol units previously transmitted to the UE which were unacknowledged by the UE.
