ABSTRACT:
There is disclosed a system and method for improving wireless system capacity by reducing collisions where the Signal to Interference Ratio (SIR) is high in systems having a channel reuse of 1. By ordering the channel assignment in each of the interfering cells according to a pattern, for example, according to the distance from a base station (determined by power levels), the mobile stations will become paired on the same channel in a manner to reduce interference between them. In one embodiment, this intelligent assignment is accomplished by assigning mobile stations in one cell such that the mobile station having the strongest signal is assigned channel A while in the interfering cell the mobile station with the weakest signal is assigned to channel A. In another embodiment, certain preferred mobile stations are assigned either interference-free channels or channels paired with weak interference mobile stations.
