On resource allocation in dense femto-deployments

Abstract

Femtocells offer a promising way of extending macrocellular network coverage to indoor residential environments. If femtocells are spaced one per home, each on it's own lot, interference low. For dense deployments, i.e. multi-unit construction, SIRS can become very low. Thus we propose a greedy frequency planning algorithm which only uses measurements at the femto-access point. Simulation results show an improvement in SIR due to using the new frequency plan.
