Abstract: The present invention relates to a method for enabling a terminal to communicate with data by modifying an association relationship among component carriers in a mobile communication system supporting carrier aggregation and an apparatus therefor. The method in accordance with one embodiment of the present invention, comprises: receiving a message including identifier information for modifying an association relationship among at least one downlink component carrier and at least one uplink component carrier from a base station; receiving predetermined data through at least one downlink component carrier from the base station; and transmitting feedback data to the base station for data received through the uplink component carrier modified according to the identifier information.

Abstract: A method is described for a device to re-establish a connection with a Donor evolved Node B (DeNB). The device communicates with the DeNB via a Un interface using a subframe for the device only. The device detects a problem associated with the Un interface, and performs a radio resource control (RRC) re-establishment procedure to re-establish a RRC connection between the device and the DeNB after detecting the problem associated with the Un interface. The device starts a timer upon detecting the problem associated with the Un interface, and releases a restriction of using the subframe for the device only, if the timer expires. An occurrence of the problem associated with the Un interface is determined in response to receiving consecutive out-of-sync indications.

Abstract: A method for random access to a base station by a user equipment (UE) in a mobile communication system using carrier aggregation in which communication is conducted over a plurality of component carriers, and a terminal for the method are disclosed. When the UE performs a contention-based random access procedure in the mobile communication system to which CA technology is applied, the UE considers an uplink grant signal as a contention resolution message when receiving the uplink grant signal from a eNB only when the uplink grant signal is received through a downlink CC corresponding to an uplink CC used to transmit a random access preamble or a third message, to thereby prevent contention resolution from being erroneously ended.

Abstract: A method and apparatus for supporting a closed subscriber group (CSG) service is provided. The apparatus includes a memory to store CSG subscription information and a processor operatively coupled to the RF unit and memory to implement a radio interface protocol. The processor accesses a base station (BS), transmits the CSG subscription information to the BS, receives an access mode from the BS where the access mode is determined based on the CSG subscription information, and negotiates with the BS with regard to a CSG service if the access mode supports a CSG to which the apparatus belongs.
