INTERFERENCE CANCELLATION IN SECTOR ANTENNA

摘要

A method of communicating in a cellular network including a multi-sector point to multipoint base station, having a plurality of antennas (104 A, 104B, 104C) covering primarily non-overlapping zones (126 A, 126B, 126C). The method includes allocating bandwidth to a subscriber station (120A, 120B) in each of the zones (126A, 126B, 126C), which bandwidth is on a single channel, such that if the subscribers (120A, 120B) were adjacent each other their transmissions on the allocated bandwidth would interfere with each other, transmitting signals from the subscribers (120A, 120B) to the base station through the antennas (104A, 104B, 104C) of the respective zones (126A, 126B, 126C) in which they are located, on the allocated bandwidth and processing the signals from each of the subscribers (120A, 120B) so as to cancel interference from others of the subscribers (102A, 120B) in interpreting the signals by the base station.
