Outage Probability Analysis for Collocated Spectrum- Sharing Macrocell and Femtocells

Free registration required

Executive Summary

Femtocells have been considered by the wireless industry as a promising solution not only to improve indoor coverage, but also to unload traffic from already overburdened macrocells. In spite of potentially excessive interference caused by densely deployed femtocells, macrocells may have to share the same spectrum with femtocells, due to spectrum availability and network infrastructure considerations. In this paper, the authors derive closed-form expressions for downlink Outage Probabilities (OP) of collocated spectrum-sharing macrocell and femtocells, based on the stochastic geometry theory.
