Abstract:
1. A method of synchronization at a target base station in a Long Term Evolution (LTE) wireless communication system, the method comprising: receiving a message, from a source base station, comprising a plurality of counts and handover continuity information for a user equipment (UE) to be handed over to the target base station, each count comprising an aggregate of a Hyper-Frame Number (HFN) and a packet data convergence protocol (PDCP) sequence number (SN), and the handover continuity information comprising data utilizable by the target base station to determine a status of one or more PDCP SNs sequenced after a latest PDCP SN provided in the plurality of counts; and performing count maintenance at the target base station based upon one or more of the handover continuity information and the plurality of counts.
