The foreseen exponential growth of mobile data traffic will not be uniform across geographical areas, but is mainly concentrated in hot spots that are usually located in the built environments (BEs) such as central business districts, stations, airports, stadiums, dense urban environments, etc. This poses considerable challenges that we believe can be solved by ultra dense deployment of millimetre-wave (mmW) small-cells (SCs) in conjunction with massive multiple-input multipleoutput (MIMO) in 5G and beyond 5G (B5G) wireless networks. However, there are a number of research challenges that need to be addressed for a successful deployment of 5G/B5G wireless networks: even if the theoretical background of massive MIMO is by now rather complete, the actual performance characterization and measurements of mmW antenna arrays has not yet been fully addressed at either the component or system level; mmW radio channel measurements have been performed but with limited time delay resolution, single antennas and over single radio links; and mmW bands have been considered for mobile communications, but the level of detail and diversity of BEs necessary for meaningful mmW SC deployment has not been fully exploited. Therefore, we propose here a research approach that combines the three disruptive key enabling technologies for 5G/B5G with the aim to answer fundamental questions that are still not well understood.
Develop and test mmW MIMO and massive MIMO antennas.
Characterize and model radio propagation channel at mmW bands for typical BEs (offices, homes, stations, airports).
Characterize and model the effect of human body on MIMO radio propagation at mmW bands.
Theoretically analyze and optimize massive MIMO mmW SC performance in the BEs.
Jointly optimize the planning/deployment of massive MIMO mmW SC networks and their operating environments.
Develop methods to retrofit existing buildings and to design new buildings for efficient high-capacity wireless
communications in the BEs.
WAVECOMBE provides 396 person-months of high quality interdisciplinary and cross-sector research training for a new generation of scientists, who will benefit directly from the entrepreneurial and creative environment created by the network, and deliver impact at a European level. It will produce a critical mass of highly-skilled professionals, who are advantaged by their international and inter-sector mobility. It will:
Develop EU capacity and skills to advance mmW antenna design, channel modelling, understanding of fundamental limits of dense small cells, HetNet planning/optimisation tool development, IoT, VR and other high data rate applications in BEs.
Integrate mmW antennas and systems more closely with BEs to facilitate smart building applications.
Create strong interactions between wireless communications and building/BE/urban design and planning.
Increase EU competitiveness in 5G/B5G, smart environment/building/city.
Develop lasting academic and industry collaboration which ensures interdisciplinary and cross-sector research training programmes.
Create new and exciting career prospects for the fellows.
