in FDD mode, data can only be transmitted and received in two separate frequency band for DL & UL however, it's done simultaneously in time domain using entire (single) time frame.Therefore, number of component carriers and BW are different. However in TDD mode, it uses only single freq band but transmission & reception is divided into time frame in such a way that data is transmitted (DL) for say first half of the frame and received (UL) in second half
