The 6G-ICARUS consortium will work on Future Wrieless Networks focusing primarily in the MillimetreWave (mmWave) and sub-Terahertz (subTHz) frequency bands. The project will generate novel research results as well as novel original hardware supported by innovative software (techniques, algorithms) based mostly on machine learning and deep learning. Hardware and software will be combined and examined in real world settings to fulfil certain situations, all of which are matched with real-world applications. To accomplish that, 6G-ICARUS project is built on three main interdisciplinary pillars: (i) Effective utilisation of reconfigurable intelligent surfaces (RISs) suitably controlled by artificial intelligence (AI) software; (ii) Channel modelling for mmWave/subTHz communications; (iii) Multi-connectivity (MCon) solutions for 6G mobile communications.
