摘要
目前超可靠低时延通信(URLLC)研究较碎片化,且侧重于某一点,因此以全景式视角,从应用场景和需求开始,介绍了URLLC相关的系统架构、关键技术和总体解决方案;然后分别对物理层检测性能需求、链路自适应、无线资源管理、端到端分集解决方案以及如何与时间敏感网络集成进行了深入的分析,并对候选方案进行了探讨。希望从广度到深度,对URLLC的理论研究以及如何应用有一个透彻全面的介绍,对其挑战有一个清晰的认识,从而为相关研究和工程技术人员提供借鉴。
The current fragmented ultra reliable and low latency communication(URLLC)research focusing on a certain point was overcome.From the perspective of panoramic view,starting from the application scenarios and requirements,the system architecture,key technologies and solutions of URLLC were analyzed and introduced.Then,the physical layer detection performance requirements,link adaptation,radio resource management,end-to-end diversity solutions and how to integrate with TSN(time sensitive network)were analyzed in depth,and possible candidates were discussed.It hopes to have a thorough and comprehensive understanding of the theoretical research and application of URLLC,and a clear understanding of its challenges,so as to play a key reference for researchers and engineers in the related fields.
