Executive Summary

The distributed Multiple-Input-Multiple-Output (MIMO) techniques across multiple cooperative Base Stations (BSs) can significantly enhance the capability of the broadband wireless networks in terms of Quality-of-Service (QoS) provisioning for wireless data transmissions. However, the computational complexity and the interfering range of the distributed MIMO systems also increase rapidly as the number of cooperative BS's increases. In this paper, the authors propose the QoS-aware BS-selection schemes for the distributed wireless MIMO links, which aim at minimizing the BS usages and reducing the interfering range, while satisfying diverse statistical delay-QoS constraints characterized by the delay-bound violation probability and the effective capacity technique.
