Abstract Femtocells are small cellular base stations targeting in-home usage and deployed by end-users. Because of the unplanned nature of their deployment, they can suffer from severe inter-cell interference with neighboring femtocells in dense deployments. In addition, coordination is hardly feasible due delays induced by the backhaul infrastructure of these home femtocell networks. We propose a novel and decentralized interference mitigation scheme that combines HARQ and incremental redundancy with an interference cancellation decoder. Our performance evaluation based on analytical modeling and Monte Carlo experiments shows that our scheme is effective at combating interference without requiring any coordination.
