Abstract：With the rapid development of the Internet of Things(IoT), modern Industrial IoT(IIoT), smart cities, intelligent Vehicle-to-Everything(V2X) networks, smart healthcare and other new IoT applications will be widely adopted. These application scenarios will place extremely high demands on network transmission rate, transmission latency, system power consumption, and the number of access points. To address these challenges, 6G networks will incorporate advanced technologies such as wide bandwidth, low power consumption, and large-scale antenna technologies, providing robust support for future IoT applications. In response to this development trend, the typical application scenarios and technical requirements of 6G-enabled IoT are focused on in the research, key enabling technologies including millimeter-wave/terahertz communications, Reconfigurable Intelligent Surface(RIS) communications, Integrated Sensing and Communication(ISAC), and Backscatter Communications(BackCom) are deeply studied, and on this basis, an outlook on the future of 6G IoT is provided.
