Dynamic maintenance method of timing synchronization for soft handover

All wireless systems require the precise timing synchronization to satisfy the higher Quality of Service (QoS) requirements. Particularly, timing synchronization between Base Stations (BSs) during soft handover is required to increase the diversity gain of soft handover. Current timing synchronization protocol (e.g. IEEE1588, GPS) updates the synchronization at fixed time duration and it causes the excess overhead. In this paper, dynamic maintenance method is proposed. Proposed maintenance method based on user's PER (Packet Error Rate) of user reduces the total triggers of synchronization and consequently shows the decreased message overhead comparison with existing synchronization methods.
