Scaling up the number of base stations per unit area and augmenting the heterogeneity of networks are two major trends in mobile cellular systems of the fourth (4G)- and fifth generation (5G), making it increasingly difficult to characterize aggregate interference statistics with system models that are characterized by a low number of parameters. This paper proposes a new circular interference model that aggregates given interferer topologies to power profiles along circles. We introduce a mapping procedure that preserves the aggregate interference statistics at arbitrary user locations within the associated cell with a certain desired accuracy. At the same time, our method identifies the amount of nodes in a given interferer topology that principally determine the shape of the interference distribution. To further refine the analysis of given power profiles, a new finite sum representation for the sum of Gamma random variables with integer-valued shape parameter is introduced. The approach allows to decompose the distribution of the aggregate interference into the contributions of the individual interferers. Such knowledge is particularly expedient for the application of base station coordination- and cooperation schemes. Moreover, the proposed method enables to accurately predict the corresponding signalto- interference-ratio- and rate statistics.
