Abstract
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.

An electronic device comprising:
- circuitry configured to
- control transmitting signals according to one of a first communication mode based on spectrum aggregation or a second communication mode not based on spectrum aggregation;
- control transmitting a trigger signal via a PSCH (Physical Shared Channel), the trigger signal indicating a change of the communication mode;
- control receiving spectrum source information for the spectrum aggregation through operating parameter information of an adjacent base station.
A wireless communication method comprising:
- controlling transmitting signals according to one of a first communication mode being based on spectrum aggregation or a second communication mode being not based on spectrum aggregation;
- controlling transmitting a trigger signal via a PSCH (Physical Shared Channel), the trigger signal indicating a change of the communication mode;
- controlling receiving spectrum source information for the spectrum aggregation through operating parameter information of an adjacent base station.
