The present invention relates to a method and a device for configuring carrier aggregation and, more particularly, to a method and a device for selecting a channel of an unlicensed band in configuring carrier aggregation for a terminal using an unlicensed band cell which uses an unlicensed frequency band. In particular, the present invention provides: a method by which a terminal performs a carrier aggregation, and which comprises the steps of: receiving, from a base station, channel candidate information of a secondary cell using an unlicensed frequency band; transmitting channel state information with respect to one or more channels generated using the channel candidate information; and adding, as the secondary cell, a channel selected on the basis of the channel state information by the base station; and a device. 本发明涉及种用于配置载波聚合的方法和装置，且更具体地涉及在通过利用使用未授权频段的未授权频段小区来为终端配置载波聚合时选择未授权频段的信道的方法和装置。特别地，本发明提供了用于终端进行载波聚合的方法和装置，该方法包括步骤：从基站接收使用未授权频段的辅小区的信道候选信息；发送根据所述信道候选信息所生成的、与个或多个信道相关联的信道状态信息；和添加由所述基站基于所述信道状态信息所选择的信道作
