Abstract
A technique for allocating frequencies in a cellular communication system. The frequency reuse plan divides all available frequencies into six groups with the frequencies assigned in an ascending index order modulo 6. A three cell reuse plan is implemented with six 60.degree. sectorized antennas per cell, and two frequency groups being assigned for use in each cell. The channel groups are allocated to the sectors such that no two adjacent sectors use the same frequency groups. As a result, an effective times one frequency reuse plan is implemented. A frequency assignment process which attempts to avoid assigning the same frequency to a mobile which is located in the outer portion of a sector which is also in use in potential interfering outer sectors of homologous cells insures that carrier to interference (C/I) ratio minimums can be met without specialized encoding techniques.
