User-centric Immersive Communications in 6G: A Data-oriented Framework via Digital Twin

Conghao Zhou, Shisheng Hu, Jie Gao, Xinyu Huang, Weihua Zhuang, Xuemin Shen

TL;DR

The paper tackles the challenge of delivering personalized immersive experiences in 6G by proposing a data-oriented network resource management framework that uses per-user Digital Twins (UDTs) to tailor data attributes, QoE definitions, and AI models. It embeds a life-cycle approach (Development, Evaluation, Update) for adaptive network modeling and resource management, supported by an architecture consisting of UDTs, a Data Management Module, Bidirectional Synchronization, and a Network Management Interface. A Mobile Augmented Reality (MAR) case study shows that DT-enabled per-user QoE modeling reduces modeling errors compared with user-agnostic approaches and demonstrates scalable, user-centric service provisioning. Overall, the work advocates integrating data-centric AI, DT-driven profiling, and end-to-end data-model coupling to enable automated, per-user immersive services in 6G.

Abstract

In this article, we present a novel user-centric service provision for immersive communications (IC) in 6G to deal with the uncertainty of individual user behaviors while satisfying unique requirements on the quality of multi-sensory experience. To this end, we propose a data-oriented framework for network resource management, featuring personalized data management that can support network modeling tailored to different user demands. Our framework leverages the digital twin (DT) technique as a key enabler. Particularly, a DT is established for each user, and the data attributes in the DT are customized based on the characteristics of the user. The DT functions, corresponding to various data operations, are customized in the development, evaluation, and update of network models to meet unique user demands. A trace-driven case study demonstrates the effectiveness of our framework in achieving user-centric IC and the significance of personalized data management in 6G.
