UE capability report method and apparatus in mobile communication system
First Claim
1. A method for reporting capability of a User Equipment (UE), the method comprising:
- generating a UE capability message comprising at least one band combination information; and
transmitting the generated UE capability message to an evolved Node B (eNB),wherein each band combination information comprises at least one band parameter including a band indicator indicating a frequency band and first band capability information and second band capability information,wherein the first band capability information and the second band capability information each include carrier aggregation (CA) information and information on a number of layers supported by the UE on the indicated frequency band, andwherein the CA information includes a single value corresponding to a maximum number of component carriers and an aggregated transmission bandwidth configuration of the band both supported by the UE on the indicated frequency band.

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.
