UE capability report method and apparatus in mobile communication system
First Claim
1. A method for reporting capability of a terminal, the method comprising:
- receiving, by the terminal, a User Equipment (UE) capability enquiry message from a base station;
checking whether an Evolved Universal Terrestrial Radio Access (EUTRA) indicator is included in the received UE capability enquiry message received from the base station;
setting, if the EUTRA indicator is included in the UE capability enquiry message, a Radio Access Technology (RAT) type of a UE capability message to EUTRA; and
transmitting, by the terminal, the UE capability message comprising at least one band combination information on at least one band combination supported by the terminal,wherein the at least one band combination information comprises at least one band parameter,wherein the at least one band parameter comprises information indicating a band, and information on carrier aggregation (CA) information and information about a number of layers, andwherein the CA information associated with aggregated bandwidth configuration and maximum number of cells of the band combination.

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.
