Abstract
A carrier aggregation method in a wireless communication system and a corresponding apparatus, the method including using one baseband including two information and two radio frequency (RF) chains for aggregation of two component carriers at first and second frequency bands for each antenna port, switching the one baseband to at least one RF chain corresponding to the component carrier characteristic of the two RF chains upon use of the first frequency band, and transmitting a signal through the switched at least one RF chain.
