ABSTRACT:
The system is comprised of a microcellular underlay to increase the coverage of a macrocellular overlay system. The frequencies are assigned to the microcells by interleaved frequency segregation. Channels are selected from the macrocell frequency groups based on a minimum channel separation from the other channels in the microcell frequency group. The channels in the microcell frequency group that are greater than a minimum channel separation from the channels in the macrocell sector i overlay are assigned to the microcell sector i.
