BATON HANDOVER TRANSITION FOR SINGLE RECEIVER USER EQUIPMENT

摘要

In baton handover in TD-SCDMA communications, a user equipment (UE) may use of a single receiver to reduce call drops during baton handover. Following uplink handover, the UE may simultaneously receive downlink communication from a target cell and a source cell when a condition is satisfied. If the UE measures a signal quality of the downlink communication of the target cell greater than a signal quality of the downlink communication of the source cell, the UE switches to the target cell and completes the handover. If the UE measures a signal quality of the downlink communication of the source cell greater than a signal quality of the downlink communication of the target cell, the UE returns the uplink to the source cell and terminates the handover. Thus the UE may avoid handover to a target cell with poor signal quality.
