Abstract: An example method is provided in one example embodiment and includes receiving feedback information from at least one controlled cell indicative of interference received at one or more user equipment devices served by the at least one cell. The at least one controlled cell is controlled by an operator associated with the at least one controlled cell. The method further includes selecting one or more user equipment devices that is determined to have received interference from at least one non-controlled cell that is greater than a predetermined threshold. The at least one non-controlled cell is not controlled by the operator associated with the at least one controlled cell. The method still further includes determining a power level for a subset of common resources from among a set of common resources shared among the at least one controlled cell based upon the received feedback information.
