To meet LTE-Advanced requirements, SUPPORT of wider transmission bandwidths is required than the 20 MHz BANDWIDTH specified in 3GPP Release 8/9. The preferred solution to this is carrier aggregation.

It is of the most distinct features of 4G LTE-Advanced. Carrier aggregation allows expansion of effective bandwidth delivered to a user terminal through CONCURRENT utilization of radio resources across multiple carriers. Multiple COMPONENT carriers are aggregated to form a larger overall transmission bandwidth.
