APPARATUS AND METHODS FOR HANDOVER IN TD-SCDMA

摘要

Apparatus and methods for handover in wireless communication include attempting, by a user equipment (UE), to perform a hard handover procedure from a first cell to a second cell, where the hard handover procedure is configured for the UE by a network; determining, by the UE, that the hard handover procedure has failed; and in response to determining that the hard handover procedure has failed, attempting, by the UE, to perform a baton handover procedure from the first cell to the second cell. In some aspects, the UE may attempt to perform the baton handover procedure without first reporting to the network that the hard handover procedure has failed. The hard handover procedure may be determined as failed when the UE determines that a Fast Physical Access Channel (FPACH) is not received from the network in response to a transmission of a SYNC_UL code from the UE to the network.
