Abstract

Long Term Evolution (LTE) has introduced Femtocells technology in cellular mobile communication system in order to enhance indoor coverage. Femtocell is low-power, very small and cost effective cellular base station used in indoor environment. However, the impact of Femtocells on the performance of the conventional Macrocell system leads interference problem between Femtocells and pre-existing Macrocells as they share the same licensed frequency spectrum. In this paper, we propose an efficient method to mitigate interference and improve system capacity in the existing Femto-Macro two tier networks. In our proposed scheme, we use a novel frequency planning for two tiers cellular networks using frequency reuse technique where Macro base stations allocate frequency sub-bands for Femtocells users on demand basis through Femtocells base stations. This novel frequency reuse technique aims to mitigate interference by improving system throughput.
