Green and Efficient RAN Architectures

This chapter deals with some topics and summarises advances done by European cooperation in science and technology IC1004 researchers. It explains advanced resource management ecosystem for both, cellular and wireless networks considering resource scheduling, interference, and power and mobility management. The chapter describes recent energy efficiency enhancements by analysing power consumption, cell switch off, and deployment strategies. It then focuses on spectrum management optimisation and cognitive radio networks with tools and algorithms specifically for TVWS. The chapter also defines and models the virtualised and cloud architecture by proposing new algorithms under realistic scenarios. It addresses to re-configurable radio for heterogeneous networking by including recent progress in resource allocation, diversity, and adaptive antenna techniques to improve capacity and energy efficiency. Without a doubt, interference mitigation is one of the most important elements in cellular systems.
