Abstract :
Due to the dense and self-deployment of home eNodeBs (HeNBs) in femtocells, serious inter-cell interference may arise without good coordination. To deal with it, a distributed interference coordination scheme for femtocells networks with carrier aggregation (CA) is proposed in this paper. Firstly, each femtocell operates on all the component carriers (CCs) of the network and gathers the information needed via local measurements. Then, based on the measurements, decisions of maintaining or releasing the component carrier are individually made by each femtocell on each component carrier. Simulation results validate the effectiveness of our proposed scheme in term of the signal to interference and noise ratio (SINR) and throughput.
