Abstract: A method for controlling an aggregated interference generated by at least two white space units in at least one point in space for at least one frequency channel is provided. A model of propagation channels from each of the white space units to each of the at least one point includes a variable with a lognormal distribution. The method comprises receiving requests for usage of white space frequency channels from the white space units. The requests include positions of the white space units. Output power limits are determined for the white space units by maximizing a utility function while fulfilling a probabilistic constraint on the amount of aggregated interference generated in each of the at least one point. A sum of lognormal variables in the probabilistic constraint is approximated by a single lognormal variable. The determined output power limits are then transmitted to the respective white space units.
