    Abstract

    The future of wireless network generations is revolving toward unlocking the opportunities offered by virtualization and digitization services, with the aim to realize improved quality-of-experience (QoE) and bring several advantages to network users. According to the rapid development in the field of network virtualization, we envision that future wireless networks will run over ubiquitous deployment of virtualized components that are controlled by artificial intelligence (AI), that is, the conceptualization of the Digital Twin (DT) paradigm. The key principle of the DT relies on creating a holistic representation of wireless network elements, in addition to decoupling the information pertaining to physical objects and dynamics, into a cyber twin. The cyber twin will then leverage this information for AI models training, and then reasoning and decision-making operations, which will be then reflected to the physical environment, for improved sustainability. Motivated by this, in this article, we dig deep into the intertwined role of wireless technologies as being enablers and enabled by the DT. Furthermore, we put a forward-looking vision of the integral role that future 6G networks are anticipated to play in order to realize an efficient DT. Finally, we sketch the roadmap toward identifying the limitations of the DT in 6G-enabled wireless networks, and open new horizons for further developments in different design aspects. © 1979-2012 IEEE.
