Base Station Pilot Management for User-Deployed Cellular Networks

Abstract

In this paper we review a 4G vision of deploying a cellular network whose infrastructure topology can be autonomously determined by cellular users. Intelligent spectrum management is required for cellular interference control and mobile handoff management etc. We study an optimization method that maximizes the cell size coverage for user-deployed base stations, e.g. femtocells. The algorithm periodically updates the pilot power configuration based on each femtocell's channel pass loss and the global traffic distribution in the network. Performance results are studied by simulation based on the WCDMA cellular standard.
