Four researchers from the German Research Center for Artificial Intelligence (DFKI) and the University of Kaiserslautern, Wei Jiang, Bin Han, Mohammad Asif Habibi, and Hans Dieter Schotten, provided a comprehensive survey on the road towards 6G communications. An in-depth examination was conducted on the factors that drive, demand, push for, and facilitate the development of the mobile system that will follow 5G.
Transitioning to 6G Communications
As the global deployment of the fifth-generation (5G) mobile communication system takes firm root, it is pivotal for both academia and industry to shift their gaze toward the horizon of the next generation. The juncture marks an opportune moment to take stock of the present and envision the future of communication technology. The research is a comprehensive survey that provides an all-encompassing overview of the sixth-generation (6G) communication system. By delving into drivers, use cases, scenarios, requirements, key performance indicators (KPIs), architecture, and enabling technologies, the survey aims to pave the way for the unfolding landscape of 6G.
Necessity and Anticipated Evolution
The inquiry is addressed by illuminating the driving forces that propel the development of 6G. These drivers encompass the projected surge in mobile traffic up to 2030, offering insight into the growth trajectory. Furthermore, the article casts its vision on potential use cases and scenarios likely to underscore the significance of 6G communications.
Quantitative Comparison and 6G Roadmapping
Technical underpinnings come to the fore as the survey delves into the intricate technical requirements of 6G. A quantitative analysis juxtaposes these requirements against those of 5G, assessed through KPIs. The comparison serves as a definitive guidepost, steering the development trajectory of 6G communications. Moreover, the state-of-the-art research endeavors and initiatives within the realm of 6G are briefly summarized, accompanied by a projected roadmap that encompasses stages from definition to regulation.
Unveiling the Potential and Visioning the Future
The survey delves into the essence of 6G by highlighting a roster of potential technologies. A nuanced exploration ensues for these technologies, unraveling their principles, advantages, challenges, and open research avenues. The technologies emerge as the building blocks of 6G, collectively shaping the foundation for its imminent realization. With each layer of exploration, the survey masterfully unfolds the essence of 6G. It comprehensively describes “What 6G may look like?” By consolidating the insights, drivers, requirements, technologies, and projections, the survey offers a holistic perspective on the trajectory that 6G communications systems are poised to take.
The survey is an illuminating guidepost, directing attention toward the future realm of 6G communications. It charts the evolution from 5G to the uncharted territories of 6G, armed with insights, foresight, and a vision bound to invigorate the pursuit of knowledge, innovation, and progress in next-generation communication systems.
