Zusammenfassung:A technique to improve the synchronization timing of a mobile station (MS) when the MS performs a hard handover (HHO) is provided. An MS is ensured to possess the correct channel descriptor information of a target base station (BS) prior to disconnecting from a current serving BS using minimal control message overhead and thus synchronization latency. Specifically, a channel descriptor information checking procedure is added into the HHO preparation phase. The HHO preparation phase refers to the stage where a handover is initiated but the MS is still connected with the current serving BS.
