Abstract
A wireless communication system in which base stations communicate with subscriber stations by exchange of data packets contained within frames. The frames, which occupy a certain time duration as well as frequency range, each include a downlink subframe from a base station to subscriber stations, and an uplink subframe used by the subscribers to send data to the base station. Each subframe includes a plurality of zones, and each base station maintains a plurality of simultaneous connections with the subscribers by transmitting packets within the zones to the relevant subscriber stations. The zones allow frequency reuse when subscribers are located in different cells served by the same base station. In addition, each connection has an associated service level requiring more or less resources within the system.
