面向6G的通信感知一体化:基于无线电波的感知与感知辅助通信

6G integrated sensing and communication:wireless sensing and sensing assisted communication

无线电波可以被利用来“看到”物理世界,实现对目标的定位、检测、成像、识别等感知功能,获取周围物理环境信息,挖掘通信能力,增强用户体验。6G将在一个系统中集成通信与感知,网络感知将使能6G成为未来万物智能的网络。介绍了通信感知一体化(Integrated Sensing and Communication,ISAC)的概念和典型的使用案例,讨论了在实践中ISAC的研究挑战。基于太赫兹提供了两个案例研究,说明了如何使用6G ISAC作为未来无线蜂窝基站和终端感知关键技术。

Radio waves can be used to“see”the physical world,implement sensing functions such as locating,detecting,imaging,and identifying objects.Obtaining information about the surrounding physical environment to form cyber world can help to explore communication capabilities and enhance user experience.6G will integrate sensing and communication in a single system.In this regard,network sensing will also enable 6G as the intelligent network of things in the future.This paper introduces the concept of integrated sensing and communication(ISAC)and typical use cases,then discusses the research challenges of implementing ISAC in practice.Based on terahertz,two case studies are provided to illustrate how 6G ISAC can be used as a key technology for future UE and base station sensing.
