Heterogeneous resource allocation in LTE based Femtocell networks

Abstract

Deployment of Femtocell within Marco Cell will improve the network coverage area of not only outdoor users but also those inside building premises. Such deployment willbenefit the network operator as it resolves the deployment of additional base station. Only concern is to allocate the resource in interference limited scenarios in Femto-Marco. The works reported in literature use identical scheduling scheme for both Marco and Femto base stations. In this paper, heterogeneous scheduling schemes are carried out at these stations, which enhanced the performance of the system without any overheads. The proposed scheme is compared with the existing scheduling algorithm in terms of throughput, spectral efficiency and delay. Algorithm is 38.63 %better compared to literature value in term of spectral efficiency.
