Creating an information society in the world is one of the most urgent and important tasks today. In such conditions 5G networks will become the most widespread telecommunication technological solution in the next decade. To ensure the European leadership in the direction of the development and deployment of 5G networks 5G PPP in close collaboration with EC supports different related activities. There were already launched the 5G PPP project of three phases. It was shown that they are closely linked. This aims to present and analyze the links between 5G-Xcast, 5GTOURS, and 5GASP projects, the continuity of the conducted research activities, and new directions of future research. There were showcased which technologies and solutions from the past projects were reused for other projects and probably will be reused for further studies. Was underlined that the most valuable is the long-term follow-up of research according to the 5G PPP research roadmap. This hopefully will help to support vendors, MNOs, SMEs, and verticals in the EU on the road to the future information society.
