A Hybrid Interference Control Scheme for Femto Cells Using Overhearing and Limited SON Co-Ordination

This paper presents a coordinated scheduling/ interference control solution with Overhearing and limited SON control. The solution is suited to many of the open access Femto cell networks being deployed, where the provision of very high bandwidth (X2 type) inter-connecting links is not feasible. The proof of concept is provided through simulations with real radio channel data. The proposed solution achieves significant cell edge SINR improvements over the Overhearing scheme, while reducing the peak and average signalling rates of the full SON control solution by 90%.
