Uplink synchronization of TD-SCDMA multiple USIM mobile terminal during handover

摘要

Certain aspects of the present disclosure provide techniques and apparatus for uplink synchronization of a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) multiple Universal Subscriber Identity Module (USIM) mobile terminal during a handover. For certain aspects, a method of wireless communication generally includes transmitting, to a Node B, at least one uplink synchronization code from a UE comprising at least a first subscriber identity and a second subscriber identity, receiving timing information for uplink synchronization to the Node B, wherein the timing information is measured based on the at least one uplink synchronization code, and applying the timing information to calls for both of the first and second subscriber identities to synchronize uplink transmissions to the Node B.
