Carrier Aggregation Bands

Carrier Aggregation (CA) is one of the key technologies in LTE-Advanced (Rel. 10 and beyond). In simple terms, CA allows multiple radio channels to be bonded together to create bigger bandwidth pipes. The channels may belong to the same or different spectrum bands. Release 10 supports both intra-band contiguous and inter-band CA in the FDD downlink but only intra-band CA for TDD downlink. Only intra-band CA is supported in both FDD & TDD uplink. More details regarding CA are available in the following Agilent presentation.
