无线电通信技术

6G将带来“全域覆盖、场景智联”的新时代网络发展愿景，面对新的趋势和挑战，移动通信系统的代际演进需要重新思考网络范式的转变。在继续提升性能指标的基础上，如何以简化的方式，解决5G发展中遗留的问题，实现多维度的跨域融合是未来网络设计的关键问题。在新场景、新业务和新技术的驱动下，以用户为中心成为业界关注的、能够助力未来网络建设、提升用户体验的研究方向。为此，提出了一种以用户为中心的系统框架设计方案，重点从统一接入和跨域协同两个关键特征展开，介绍包括状态管理、灵活空间等在内的关键使能技术，阐述以用户为中心如何更好的支持6G网络深度融合。最后，对以用户为中心技术在6G的发展进行了展望，其可以支撑未来6G高效网络赋能新场景、新业务下的完美用户体验，同时需要应对一体化空口设计、跨域功能管理和协同等方面的挑战。

The 6G will bring a new era of network development with the vision of “ubiquitous coverage and intelligent interconnection of scenes”.Faced with new trends and challenges, the intergenerational evolution of mobile communication systems needs to rethink the transformation of network paradigms.On the basis of continuing to improve performance indicators, how to solve the problems left over from the development of 5G in a simplified manner and achieve multidimensional cross-domain integration is a key issue in future network design.Driven by new scenarios, new businesses, and new technologies, user-centric technology research has become a focus of the industry and academia, providing great help in the construction of future networks and enhance user experience.For this reason, a user-centric system framework design is proposed, focusing on two key features: Unified access and cross-domain collaboration.Key enabling technologies including status management and flexible space are introduced, elaborating on how to better support the deep integration of the 6G networks with a user-centric approach.Finally, the development of user-centric technology in 6G is prospected, which can support the perfect user experience in new scenarios and new services enabled by future 6G efficient network,and needs to face the challenges of integrated air interface design, cross-domain function management and collaboration.
