ABSTRACT:
A method for configuring a spread spectrum cellular network for small-cell inclusion, by providing a finite series of PN-offsets, each PN-offset is separated by a constant value that is allotted to the spread spectrum cellular network. The finite series is portioned into a first and a second set. The second set subsequent to the first set and having sufficient PN-offset elements for a PN-offset reuse pattern having a plurality of cells, each cell having similar transmission characteristics. The second set is assigned to the PN-offset reuse pattern, deploying the cellular reuse pattern for a cellular network. Small cells are insertable into the spread spectrum cellular network by assigning the first set to a PN-offset reuse pattern having a plurality of small cells arranged in a small-cell reuse pattern, and deploying the small-cell reuse pattern. In another aspect, the method for configuring the spread spectrum cellular network involves sectoring each cell of the plurality of cells into a plurality of sectors. The sectored cells are assigned PN-offsets adjacent in the finite series together in each sector of the sectored cell while maintaining sufficient distance between cells that reuse an assigned PN-offset.
