Outline of Final Research Achievements

Due to the severe spectrum crunch, current wireless communication systems will soon be unable to cope with the sharp increase of the amount of mobile data traffic. To face this issue, this project mainly focused on the design of wireless resource allocation and interference management solutions for Cloud Radio Access Networks (CRAN) and Fog Radio Access Networks (FRAN) for 5G and Beyond 5G systems. In particular, a non-orthogonal scheduling method was proposed, whereby each basic radio resource unit was shared among multiple users by leveraging the Cloud/Fog functionalities. The proposed approach enabled to reduce the amount of resource consumption in terms of spectrum and energy, while jointly improving the overall system performance and user fairness, as well as the users’ satisfaction levels of their quality of service requirements.
