A system, which has an aerial-staying type communication relay apparatus that wirelessly communicates with a terminal apparatus, is provided with plural gateway stations that perform space-division multiplexing communication for transmitting and receiving different relay signals from each other on a same frequency in a feeder link with the aerial-stay type communication relay apparatus. Each of the plural gateway stations may be provided with an antenna control section that controls an antenna for feeder link so as to track the aerial-stay type communication relay apparatus.
