Abstract:
1. A wireless base-station system which performs wireless communication with mobile terminal devices which exist in a plurality of service areas, the system comprising: a base-station main apparatus which performs processing on a baseband signal for each mobile terminal device; a plurality of local wireless apparatuses which are installed in sub areas into which each service area is divided, the local wireless apparatuses performing wireless communication with the mobile terminal devices and transmitting/receiving the baseband signal for each mobile terminal device to/from the base-station main apparatus; and a baseband server which distributes a downlink signal, containing the baseband signal to be transmitted from a high-order apparatus to the mobile terminal device via the base-station main apparatus, to the local wireless apparatuses installed in the sub areas in the service area in which the mobile terminal device exists, the baseband server combining multiple uplink signals, containing the baseband signals to be transmitted from the mobile terminal devices to the high-order apparatus via the local wireless apparatuses, and transmitting a resulting uplink composite signal to the base-station main apparatus, wherein the baseband server generates the uplink composite signal by determining an average value of multiple uplink signals received from the respective local wireless apparatuses installed in the sub areas.
