Optimized Dual Relay Deployment for LTE-Advanced Cellular Systems

LTE-Advanced adopts relay deployment to support higher data rates and better coverage, especially at the cell edges which suffer from inter-cell interference. The solution of relaying is attractive because of its low cost and easy deployment. In this paper, the authors show that deploying just two relays per sector can significantly improve system capacity and coverage. They optimize the geometric deployment of relays that maximizes the spectral efficiency of the worst users or minimize outage. They consider the effects of different backhauling techniques such as wirelessly connected relays or wired radio remote heads.
