In addition, the above embodiments have been described using the case of two clusters as an example. However, the present invention is not limited to the present case, and the same can be applied to three clusters or more.

Although a case has been described with the above embodiments as an example where the present invention is implemented with hardware, the present invention can be implemented with software in cooperation with hardware.

Each function block employed in the description of each of the aforementioned embodiments may typically be implemented as an LSI constituted by an integrated circuit. These may be individual chips or partially or totally contained on a single chip. “LSI” is adopted here but this may also be referred to as “IC,” “system LSI,” “super LSI,” or “ultra LSI,” depending on the differing extents of integration.

The method of implementing integrated circuitry is not limited to LSI, and implementation by means of dedicated circuitry or a general-purpose processor may also be used. After LSI manufacture, utilization of a Field Programmable Gate Array (FPGA) or a reconfigurable processor where connections and settings of circuit cells in an LSI can be regenerated is also possible.

In the event of the introduction of an integrated circuit implementation technology whereby LSI is replaced by a different technology as an advance in or derivation from semiconductor technology, integration of the function blocks may of course be performed using that technology. The application of biotechnology is also possible.

Although the present invention has been described above with embodiments using antennas, the present invention is equally applicable to antenna ports.
