Abstract
An apparatus and a method for a carrier aggregation (CA) operation using a Frequency Division Duplex (FDD) carrier and a Time Division Duplex (TDD) carrier in a wireless communication system are provided. The method includes receiving downlink signals via downlink FDD TDD 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.
