A wireless communication system, using wireless base stations, and other devices, such as a relay node, interoperate with using spectrum aggregation and MIMO. Traffic usage is detected and based on channel utilization relative to capacity, spectrum aggregation is chosen over MIMO under certain conditions. On the other hand, under higher channel utilization system components switch to MIMO modes of operation to reduce demand on channel use, while providing good throughput for communications stations.
