Abstract: A method of communicating in a cellular network including a multi-sector point to multipoint base station, having a plurality of antennas covering primarily non-overlapping zones. The method includes allocating bandwidth to a subscriber station in each of the zones, which bandwidth is on a single channel, such that if the subscribers were adjacent each other their transmissions on the allocated bandwidth would interfere with each other, transmitting signals from the subscribers to the base station through the antennas of the respective zones in which they are located, on the allocated bandwidth and processing the signals from each of the subscribers so as to cancel interference from others of the subscribers in interpreting the signals by the base station.
