Evolution of broadband wireless systems towards 5G

5G systems will be characterized by innovative paradigms in the development and use of communications services, with very tight and heterogeneous specifications and operational requirements.

ITU has identified three main use cases for 5G systems: enhanced mobile broadband (eMBB), massive machine type communications (MMTC), ultra reliable and low latency communications (URLLC). The research activity will be focused on the study of different 5G scenarios and will analyse the possible scenarios for migrating from existing systems to the 5G. For the definition of the possible use cases, 5G technologies will be considered as applied to new sectors, resulting from the progressive penetration of the telecommunications in various fields like transport, medicine, energy or industry.

FUB will study and assess possible interference issues that may arise due to the introduction of 5G technologies alongside the existing radio systems in the different frequency bands envisaged for 5G uses both above and below 6 GHz. Specific analysis will be carried out through simulation and experimental studies - depending on the maturity and availability of technologies – particuarly considering the pioneer bands identified in Europe for the early realisation of 5G before 2020, that is the 700 MHz band, the 3.4-3.8 GHz band and the 24.25-27.5 GHz band. To this end, radioelectric and propagation characteristics airwaves will be studied at different frequencies, also in relation to the technical parameters, the specific radio techniques and the use cases applicable to these bands (eg. Massive MIMO systems distributed antenna, etc.).
