6G Vision, Value, Use Cases and Technologies From European 6G Flagship Project Hexa-X

While 5G is being deployed and the economy society begin to reap associated benefits, research development community starts focus on next, 6th Generation (6G) of wireless communications. Although there are papers available in literature visions, requirements technical enablers for 6G from various academic perspectives, a lack joint industry work towards 6G. In this paper consolidated view vision, values, use cases key enabling technologies leading stakeholders academia presented. The authors represent mobile communications ecosystem with competences spanning hardware, link layer networking aspects, as well standardization regulation. second contribution revisiting analyzing concurrent initiatives A third identification justification six challenges: (i) “connecting”, sense empowering, exploiting governing, intelligence; (ii) realizing network networks, i.e., leveraging existing networks investments, while reinventing roles protocols where needed; (iii) delivering extreme experiences, when/where (iv) (environmental, economic, social) sustainability address major challenges current societies; (v) trustworthiness an ingrained fundamental design principle; (vi) supporting cost-effective global service coverage. fourth comprehensive specification concrete first-set jointly defined 6G, e.g., massive twinning, cooperative robots, immersive telepresence, others. Finally, anticipated evolutions radio, management/orchestration domains discussed.
