用数字孪生实现6G沉浸式通信的个性化服务
User-centric Immersive Communications in 6G: A Data-oriented Framework via Digital Twin
- 为每位用户建立数字孪生，按需定制数据管理
- 通过用户行为建模提升多感官体验质量
- 适合研究6G个性化网络与数字孪生应用者
本文提出一种面向6G沉浸式通信（IC）的新型用户中心服务框架，旨在应对个体用户行为不确定性并满足其独特的多感官体验质量要求。该框架采用数据驱动方式管理网络资源，支持针对不同用户需求的个性化数据管理。核心是利用数字孪生（Digital Twin, DT）技术，为每位用户构建专属DT，并根据用户特征定制其数据属性。在模型开发、评估与更新过程中，针对不同数据操作定制相应功能，以精准响应用户独特需求。基于实际轨迹的案例研究验证了该框架在实现用户中心化沉浸式通信中的有效性，凸显了个性化数据管理在6G中的关键作用。
原文摘要 · Abstract (English)
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.
