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.

A device (110) receives a radio link control (RLC) protocol data unit (PDU) (740) or service data unit (SDU) (760) to be segmented, defines a padding threshold (840) for a segmentation mechanism, and determines a padding ratio (850) after enhanced dedicated channel transport format combination (ETFC) selection (730). The device selects a first transport block (960) and a second transport block (970) associated with the RLC PDU/SDU (740/760) when the padding ratio (850) is greater than or equal to the padding threshold (840), and generates a modified segmentation of the RLC PDU/SDU (740/760) based on the first and second transport blocks (960/970) when a padding ratio (RTB) associated with the first and second transport blocks (960/970) is less than the padding threshold (840) and a size ratio (STB) associated with the first and second transport blocks (960/970) is within a size threshold (980).
