摘要：
A method and apparatus for minimizing data forwarding between Evolved Node Bs (ENBs) during a handover. A User Equipment (UE) sends a status report to an ENB of a source cell immediately before the handover occurs. In this manner, a target cell avoids retransmission of the RLC PDUs, which were successfully transmitted but have not yet been ACKnowledged (ACKed) by the UE, thereby minimizing the amount of data being forwarded from the ENB of the source cell to an ENB of the target cell.
