Heterogeneous networks constitute a promising solution to the emerging challenges of 5G networks. According to the specific network architecture, a macro-cell base station (MBS) shares the same spectral resources with a number of small cell base stations (SBSs), resulting in increased co-channel interference (CCI). The efficient management of CCI has been(More)
The stringent requirements defined for 5G systems drive the need to promote new paradigms to the existing cellular networks. Dense and ultra-dense networks based on small cells, together with new spectrum sharing schemes seem to be key enabling technologies for emerging 5G mobile networks. This article explores the vision of the SPEED-5G project, analyzing(More)
This paper presents the vision and some early results achieved by the EU-funded SPEED-5G project which is part of 5G PPP [1]. It addresses some key challenges of future 5G systems, i.e. a 1000 times higher capacity, a much lower latency and a much improved user quality of experience compared to currently deployed networks. The devised new technologies are(More)
