Claim Text:
1. A method for mitigating interference and reducing spectrum costs, comprising: initializing, by a circuitry, at least one ungrouped femtocell base station; initializing, by the circuitry, a location index corresponding to the location of the ungrouped femtocell base station; initializing, by the circuitry, a grouping index of the at least one ungrouped femtocell base station to an initial value; initializing, by the circuitry, a first group and setting a number of femtocell base stations in the initialized first group to the initial value; assigning, by circuitry, the at least one ungrouped femtocell base station to the first group to be a grouped femtocell base station; setting, by the circuitry, the grouping index of the grouped femtocell base station to a non-initial value; selecting, by the circuitry, at least one other ungrouped femtocell base station for evaluation; assigning, by the circuitry, the at least one other ungrouped femtocell base station to the first group if the distance between the grouped femtocell base station and the at least one other ungrouped femtocell base station is larger than a threshold distance value; and setting, by the circuitry, a grouping index of the at least one other ungrouped femtocell base station to the non-initial value.
