Abrégé

A method for synchronization in a Wideband Code Division Multiple Access (WCDMA) system. The method introduces a globe synchronization time to the WCDMA system as a reference time for signal transmitting of all NodeBs; when searching adjacent cells or making handover, each UE takes this reference time as a reference time; in this way, the UE design complexity is reduced, the UE available time is increased, the handover signaling is simplified and the handover success and reliability are increased too. Therefore, the method increases system capacity and makes service quality better.
