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.
