Abstract:
1. A wireless communication system for performing communication between a base station and a plurality of terminal stations by using a contention method to assign a different slot in response to a transmission request from each of the terminal stations, the base station comprising: a plurality of antennas disposed such that a plurality of wireless zones cover mutually different areas; a plurality of wireless units connected to the plurality of antennas in one-to-one correspondence, and being operable to, via the respective antennas, receive wireless signals from the terminal stations in the wireless zones, and transmit wireless signals to the terminal stations in the wireless zones; a data processing unit operable to process the wireless signals received by the plurality of wireless units, as well as generate data to be transmitted to the plurality of terminal stations; and a communication control unit operable to control the plurality of wireless units so as to, during a slot other than a transmission request slot, form one communication area combining the wireless zones of all of the antennas, and during the transmission request slot, form a plurality of mutually independent communication areas less than or equal in number to the plurality of antennas.
