The present invention relates to a method and apparatus for configuring carrier aggregation and, more particularly, to a method and apparatus for selecting a channel of an unlicensed band when configuring the carrier aggregation in a terminal by using an unlicensed band cell which uses an unlicensed frequency band. Particularly, a method for performing, by the terminal, the carrier aggregation comprises the following steps: receiving, from a base station, channel candidate information of a secondary cell which uses an unlicensed frequency band; transmitting channel status information on one or more channels generated by using the channel candidate information; and adding, by the base station, a channel selected based on the channel status information as the secondary cell. |
