Hybrid Cognitive Approach for Femtocell Interference Mitigation
Original language description
In this paper, we introduce new concept for femtocells with the purpose to minimize cross-tier interference to the macrocell users (MUEs). The cross-tier interference is mitigated by the power control algorithm minimizing the power level and, thus, ensuring that all currently active femto users (FUEs) can attach to the femto access points (FAPs). To guarantee quality of service to the FUEs even at heavy load, despite low transmitting power, the FAPs can opportunistically utilize also SU bands. To that end, we denote our scheme as a hybrid cognitive approach, which is distinguished by the fact that the FAPs can access bandwidth as a primary users (PU) and secondary users (SU) at the same time. In order to generate less overhead introduced by sensing forthe purpose of determining available spectrum, we also propose an algorithm that adaptively changes a sensing period. The results show that our proposal is able to significantly reduce cross-tier interference nearly to the same level as
