11 Claims

1. A method comprising:

receiving an early measurement report configuration that configures UE early measurement reports from a serving cell by a user equipment (UE) in a wireless network;

receiving an early handover command by the UE from the serving base station, wherein the early handover command includes at least one early handover elements comprising a handover candidate cell list of handover candidate cells, corresponding triggering condition for each handover candidate cell on the handover candidate cell list;

monitoring triggering conditions for candidate cells on the handover candidate cell list based on a UE-triggered handover configuration;

subsequently, receiving a network-triggered handover command to a target cell;

suspending the UE-triggered handover configuration; and

performing a network-triggered handover to the target cell;

wherein the UE discards the UE-triggered handover configuration upon a successful completion of a network-triggered handover to the target cell.
