Abstract
Techniques for performing handover of a user equipment (UE) in a cell-to-base station manner are described. The UE may receive a handover command to perform handover from a source base station to a target base station. The source base station may send context information for the UE to the target base station, and the context information may be available to all cells of the target base station. The UE may attempt handover from a serving cell of the source base station to a first cell of the target base station. The UE may attempt handover to a second cell of the target base station if the handover to the first cell fails. The UE may (i) receive the first and second cells from the source base station or (ii) receive only the first cell from the source base station and determine the second cell based on broadcast system information.
