Method and apparatus for enhancement of synchronization for TD-SCDMA baton handover
First Claim
Patent Images
1. A method of wireless communication for Time Division Synchronous Code Division Multiple Access (TD-SCDMA) baton handover comprising:
- switching an uplink (UL) from a source cell to a target cell at a first time;
receiving a Synchronization Shift (SS) command from the source cell at a second time, wherein the SS command is generated by the target cell; and
switching a downlink (DL) from the source cell to the target cell at a third time,in which the first time is before the second time and the second time is before the third time.

Abstract
A method and apparatus for wireless communication comprising switching an uplink (UL) from a source cell to a target cell; and receiving a Synchronization Shift (SS) command from the source cell, wherein the SS command is generated by the target cell. In one aspect, the method and apparatus further comprise switching a downlink (DL) through the target cell; completing a physical channel reconfiguration; and sending a Physical Channel Reconfiguration Complete message to the Radio Network Controller (RNC) through the target cell.
