In this paper, we describe the setup of a planned cellular testbed in downtown Dresden, Germany. It is developed by Technische Universität Dresden in cooperation with various other project partners within the German research project EASY-C. Aim of the testbed is the development and evaluation of innovative physical layer algorithms for next generation mobile communications systems. While the testbed is based on a baseline implementation of the 3GPP LTE physical layer, the focus of the research will be on techniques beyond LTE, such as multi-cell signal processing (often referred to as network MIMO) and cooperative or non-cooperative relaying. These schemes are known to be suitable for inter-cell interference cancelation and to thus strongly improve the spectral efficiency and fairness of cellular systems in theory, but have so far not been evaluated in practise. The testbed will furthermore allow the development and evaluation of improved simulation methodology for next generation mobile communication systems. The authors explain the testbed infrastructure, the hardware architecture and the algorithms of interest.
