In this paper we investigate interference management techniques for uncoordinated and dense residential LTE-Femto cell deployments implementing LTE Release-10 with closed subscriber group configuration. In particular we outline the possible interference management techniques defined in the standard. We present a distributed and centralized interference management strategy operating in the frequency domain. We evaluate the presented strategies for a dense deployment with closed subscriber groups and a scenario where multiple operators share the same band. Our results show that the distributed scheme performs similar to the centralized scheme and that both schemes outperform reuse one.
