Abstract
A subscriber unit communicates with a base station in the communication system. The base station uses a group of frequencies within a predetermined coverage area. The coverage area is divided into N concentric regions which in turn are divided into M sectors to define M.times.N concentric sector areas. The subscriber unit communicates with the base station over a set of frequencies associated with the respective concentric sector area that the subscriber unit is located. Each concentric sector area is assigned one of the group of frequency sets. The assigned frequency set for any given concentric sector area is different than the frequency sets assigned to any other concentric sector area adjacent to that concentric sector area.
