Description du projet
Aborder les enjeux du trafic de données grâce aux ondes millimétriques et à la technologie MIMO massif
La croissance rapide du trafic de données mobiles se fait particulièrement sentir dans les points chauds tels que les quartiers d’affaires, les aéroports et les stades, ce qui pose des problèmes importants pour les réseaux sans fil 5G et au-delà de la 5G (B5G). Pour relever ces défis, un déploiement extrêmement dense de petites cellules à ondes millimétriques et une technologie MIMO (entrées multiples, sorties multiples) massif sont indispensables. Cependant, la caractérisation des performances, les mesures des canaux radio et le déploiement des petites cellules à ondes millimétriques dans les environnements bâtis présentent des lacunes. Financé par le programme Actions Marie Skłodowska-Curie, le projet WAVECOMBE combinera des technologies habilitantes clés pour les réseaux 5G/B5G afin d’aborder des enjeux fondamentaux. Les activités de recherche impliqueront notamment le développement et l’essai de petites cellules à ondes millimétriques et d’antennes de MIMO massif, la caractérisation des canaux de propagation radio et l’optimisation des performances des réseaux utilisant des petites cellules de MIMO massif et à ondes millimétriques.
Objectif
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.
Hence, the research objectives of the project are as follows:
• 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).
• Theoretically analyse and optimise massive MIMO mmW SC performance in the BEs.
• Integrate massive MIMO mmW SC networks with their operating environments.
• Develop methods to retrofit existing buildings and to design new buildings for efficient high-capacity wireless communications in the BEs.
