1. A method, comprising:

  • receiving, at a server that is communicatively coupled with a plurality of cells, a plurality of performance metrics from the plurality of cells, the plurality of performance metrics comprising;

    a first performance metric representing an overall throughput performance of all user equipment devices associated with a first cell of the plurality of cells, when the first cell is potentially allocated a first resource allocation value for a fractional frequency reuse portion of the first cell'"'"'s frequency spectrum; and

    a second performance metric representing an overall throughput performance of all user equipment devices associated with the first cell when the first cell is potentially allocated a second resource allocation value, different from the first resource allocation value, for the fractional frequency reuse portion of the first cell'"'"'s frequency spectrum;

    determining, at the server, a fraction of resources for allocation within the fractional frequency reuse portion of the frequency spectrum for each of the plurality of cells, based upon the received first and second performance metrics, wherein the plurality of cells includes the first cell and a second cell and wherein the first cell does not neighbor the second cell;

    determining, for each of the plurality of cells, a fraction of the resources for allocation within a reuse one portion of the frequency spectrum based upon the determined fraction of resources for allocation within the fractional frequency reuse portion of the frequency spectrum for the respective cell; and

    transmitting, from the server to each of the plurality of cells, the fraction of resources for allocation within the fractional frequency reuse portion of the frequency spectrum for the respective cell.
