Communication method using carrier aggregation and device for same
The present invention relates to a method for transmitting and receiving a signal by a terminal in a wireless communication system supporting carrier aggregation. A method for transmitting and receiving a signal by a terminal can comprise the steps of: receiving configuration information about component carrier aggregation; on the basis of the configuration information, configuring a primary component carrier in a licensed band and configuring a secondary component carrier in an unlicensed band; transmitting data in a first subframe of the secondary component carrier; and receiving in a second subframe a response to the data. If the primary component carrier in the licensed band is configured as a component carrier on a TDD mode, the second subframe can be configured on the basis of a HARQ-ACK timing in a first condition.
