<p>A technique is provided for performing, by a mobile station (MS), a random access-free and intra-base station (BS) handover from a serving cell to a target cell by the MS using a time offset value (e.g., timing advance) for synchronization with the target cell that was used by the MS for the serving cell, both the serving cell and the target cell being provided by the same BS and antenna system. Also, a synchronized group handover may be performed for a group of MSs using a random access-free and intra-BS handover in which a same switch time indicator is provided in a handover command to each of the MSs of the group to synchronize the handover for the group to the target cell. These techniques may be used, for example, to provide fast handover after cell deployment changes, such as vertical sectorization where a new cell has been added.</p> |
