Abstract: A method and an apparatus for reporting a capability of a User Equipment (UE) supporting advanced functions such as Carrier Aggregation (CA) are provided. The method includes checking, when a control message requesting a capability report is received, a Radio Access Technology (RAT) type and transmitting, when the RAT type is set to Evolved Universal Terrestrial Radio Access (EUTRA), at least one band combination information on at least one band combination supported by the terminal. The UE capability report method is capable of reporting the UE capability related to advanced functions, such as CA and Multiple Input Multiple Output (MIMO), to a network efficiently with the least amount of information, thereby resulting in an improvement of radio resource efficiency.

Abstract: The present invention relates to a method and apparatus for performing a discontinuous reception (DRX) operation while transceiving data using a plurality of carriers in a mobile communication system. The communication method for a terminal according to one embodiment of the present invention comprises the steps of: receiving a control message, including setting information of a secondary serving cell (SCell) to be added and discontinuous reception setting information, from a primary serving cell (PCell); and applying, if the control message includes an indicator indicating that the first base station to which the SCell to be added belongs and the second base station to which the PCell belongs are different from each other, the DRX setting information to the serving cell of a first base station. According to one embodiment of the present invention, a discontinuous reception (DRX) operation is applied upon the occurrence of inter-base-station carrier aggregation, thus reducing the consumption of a battery.

Abstract: A method and an apparatus for performing random access and uplink transmission of a User Equipment (UE) supporting Carrier Aggregation (CA) are provided. The method includes determining whether a Scheduling Request (SR) is pending, determining, when the SR is pending, whether an uplink transmission resource is available in a current Transmission Time Interval (TTI), determining, when the uplink transmission resource is not available, whether a Physical Uplink Control Channel (PUCCH) resource is configured for transmission of the SR, and initiating, when the PUCCH resource is not configured, a random access process in a primary cell. The random access method and apparatus of the present invention is advantageous to reduce the waste of transmission resources.
