ABSTRACT:
This invention provides a controller of multiplex number in spatial domain that collects from a plurality of radio communication apparatuses the number of terminals connected thereto and the multiplex number in spatial domain, determines the ratio of (the number of terminals connected thereto)/(the multiplex number in spatial domain) for each radio communication apparatus, and adjusts the multiplex number for each radio communication apparatus so that the above ratio will be equal between or among the radio communication apparatuses. The radio communication apparatuses transmit the number of terminals connected thereto and the multiplex number in spatial domain to the controller of multiplex number in spatial domain.
