Abstract: An apparatus for a terminal in a wireless communication system includes a receiver configured to receive frame configuration information used by a second carrier which is operated using a Time Division Duplex (TDD) scheme and receive downlink data through downlink TDD-Frequency Division Duplex (FDD) Carrier Aggregation (CA) using a first carrier and the second carrier operated using an FDD scheme and a transmitter configured to transmit uplink data via the first carrier. The downlink data received via the second carrier is received through a downlink subframe identified by the frame configuration information.
