DEVICE AND METHOD FOR TIME DIVISION DUPLEX AND FREQUENCY DUPLEX CARRIER AGGREGATION IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for operating a terminal in a wireless communication system, the method comprising:
- receiving a downlink signal using downlink Frequency Division Duplex (FDD)-Time Division Duplex (TDD) Carrier Aggregation (CA) which uses a first carrier operated using an FDD scheme and a second carrier operated using a TDD scheme; and
transmitting an uplink signal corresponding to a downlink signal received over the first carrier and a downlink signal received over the second carrier, over the first carrier.

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.
