Abstract: Disclosed is a communication method in a wireless communication system on the basis of a carrier aggregation. The communication method on the basis of a carrier aggregation comprises the steps of: receiving a PDSCH from a base station via a subframe n of a TDD cell; and transmitting, to the base station, a PUCCH including a response to the PDSCH via a subframe n+4 of an FDD cell. Accordingly, an HARQ process may be performed efficiently.
