Claim One:
1. A method of optimizing frequency allocation in a radio access network (RAN) that includes a plurality of RNs each associated with a cell and a SN operatively coupled to the RNs, the method comprising: dividing the RNs in the RAN into a plurality of clusters of RNs; generating a FFR pattern for each cluster; allocating transmission frequencies to the RNs in each cluster in accordance with the respective FFR pattern that is generated for each cluster; estimating bit rates of one or more user equipments (UEs) associated with each cell; performing a scheduling emulation within each cell using the estimated bit rates for the one or more UEs; and combining the results of the scheduling emulations for each cell to obtain a systemwide performance metric, and if the systemwide performance metric is less than a target threshold, then repeating one or more of the dividing, generating, allocating, estimating, performing, and combining steps, until the systemwide performance metric meets or exceeds the target threshold.
