Abstract:
The present invention relates to a method and apparatus for determining radio link failure between the UE and the eNB in a wireless communication system. Particularly, the present invention provides a method and apparatus for determining radio link failure efficiently in such a way that the UE measures the radio link quality of the anchor carrier, the radio link qualities of the aggregated carriers, and the radio link quality of neighbor cells in order, and determines whether the radio link quality fulfills a predetermined condition.
