"Upcoming Challenges in Cellular Mobile Communications";
Hauptvortrag: COMONSENS Meeting, Vigo, Spain (eingeladen); 03.07.2013.

While 4th generation Long Term Evolution (LTE) technology is currently being rolled out in many countries world-wide, new challenges already arise for the near future. This talk provides an overview of what performance, based on measurements, we can expect in LTE transmissions. We will show that multi-user transmissions with multiple antennas (MU-MIMO) are still an open field to explore in which many substantial improvements are to be expected. We further discuss how to address in future high mobility scenarios as they may occur in airplane to ground station connections or high speed trains. A large area of research is today related to interference mitigation techniques. Modern heterogeneous networks (HetNet) allow the interoperability of low cost pico and nano base stations at the expense of increased interference. Modern machine type communications (M2M) will enlarge such interference even more and needs to be addressed as well. The presentation will discuss all such open problems and demonstrate first steps in the direction of solving them.
