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.

Abstract: The present invention is for supporting carrier aggregation (CA) using multiple carriers in a wireless communication system and provides a terminal operation method comprising the steps of receiving downlink signals via downlink frequency division duplex (FDD)-time division duplex (TDD) carrier aggregation (CA) using a first carrier operated in an FDD mode and a second carrier operated in a TDD mode and transmitting, via the first carrier, uplink signals corresponding to the downlink signals received via the first and second carriers. The present invention also includes embodiments other than the aforementioned embodiment.
