Tutorial Title:
Digital Twin for 6G: Taxonomy, Research Challenges, and the Road Ahead

Date: TBA


6G networks require the stringent quality-of-service (QoS) requirements in terms of very high data rate, ultra-high success reception rate, and very low latency. Supported by high QoS wireless communications, digital twin has become a game-changing technology in many applications including smart city, manufacturing, automotive, gaming, entertaining, and climate resilience. Edge computing-based wireless ultra-reliable and low-latency communications (URLLC) in 6G has been considered as a key technique to realise the full potential of digital twin. At the same time, Open RAN (O-RAN) Alliance is actively working towards transforming the radio access networks (RAN) industry in a way that both its physical and logical RAN products will be more open, smarter, interoperable, and scalable than contemporary deployments. In this way will be possible to address the inevitable traffic overload of the current networks caused by an expected mobile data traffic explosion, which according to ITU-R will be up to 5016 exabyte per month. Also in this context, the novel and recent concept of DT will play an important key role. Indeed, empowered with artificial intelligence (AI) and machine learning (ML) based mechanisms, DT will support the development of key functionalities of O-RAN architecture like non-real-time (Non-RT) and near real-time (Near-RT) RAN intelligent controller (RIC) modules, used to perform powerful AI aided network performance optimisations. This tutorial discusses a joint communications and computation design of URLLC multi-tier computing in 6G that supports digital twin networks, as well as a possible DT based approach for the implementation of both Non-RT and Near RT modules in O-RAN. Fundamental requirements, but also enabling technologies, visions, and future challenges will be discussed.
