Abstract

Abstract:

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.

Key words: integrated sensing and communication, THz, high resolution imaging, sensing assisted communication, 6G
