Abstract

Carrier aggregation is a key technology in the LTE-A. Carrier aggregation can be achieved within the same frequency bands continuous carrier aggregate, non-continuous carrier aggregation and different frequency bands within the carrier aggregation. It analyses the two implementations of carrier aggregation: MAC layer aggregation and physical layer aggregate. Combined with demand for power applications, the carrier aggregation HARQ hybrid scheduling control policy is applied, then proposes subcarrier allocation method of the 230MHz band. It can realize the 230MHz frequency band wireless communication system by using carrier aggregation and spectrum-sensing technology. And then completed functional testing in laboratory. It validates that the system does not affect the original 230MHz radio at work.
