Title:
CONDITIONAL HANDOVER ENHANCEMENT WITH CANDIDATE TARGET CELL PRIORITIZATION
Document Type and Number:
WIPO Patent Application WO/2024/092615
Kind Code:
A1
Abstract:
Methods and apparatus are provided for conditional handover (CHO) with prioritization of candidate target cells in a wireless network. A user equipment (UE) may receive, from a base station, a CHO configuration including configured priority values respectively associated with a set of the candidate target cells in the wireless network. The UE measures reference signals from the candidate target cells and reports corresponding measurement values to the base station. In a handover execution phase of a CHO procedure, the UE determines that a plurality of the candidate target cells satisfies a CHO condition, selects a target cell from among the plurality of the candidate target cells that satisfies the CHO condition based on a highest of the configured priority values or a default priority value, and completes a handover to the target cell.
