Abstract: The present disclosure relates to an access network node for a wireless communication system. The access network node is configured to act as a source access network node or as a target access network node, and comprises a transceiver configured to receive a handover instruction from a control device, the handover instruction comprising a handover time instance for a user device, a processor configured to serve the user device by maintaining a data connection with the user device until the handover time instance, and share an Automatic Repeat Request/Hybrid Automatic Repeat Request, ARQ/HARQ, process with a target access network node for the user device; or serve the user device by maintaining a data connection with the user device after the handover time instance, and share a ARQ/HARQ process with a source access network node for the user device.
