Abstract
Disclosed herein is a method for fractional frequency reuse with ordering scheme (FFRO) to increase capacity of orthogonal frequency division multiplexing (OFDM) systems while reducing interference due to the use of a common sub-channel set. Each cell includes a common sub-channel set assigned in common to all cells provided in a cluster and a dedicated sub-channel set assigned differently to all of the cells. The method includes classifying the cells into at least one type according to cluster sizes, and allocating the dedicated sub-channel set by frequency partitioning scheme based on the cell type.

A method for fractional frequency reuse with ordering scheme (FFRO) to increase capacity of orthogonal frequency division multiplexing (OFDM) systems, in which the frequency includes a common sub-channel set assigned in common to all cells provided in a cluster and a dedicated sub-channel set assigned differently to all of the cells, the method comprising:
- classifying the cells into at least one type according to cluster sizes;
- and
- allocating the dedicated sub-channel set by frequency partitioning scheme based on the cell type.
