Abstract

Although Internet of things (IoT) can enhance the quality of people’s life

but it also brings the problems of energy consumption and network transmission congestion.To solve the above problems

backscatter communication technology for zero-power IoT has been proposed.Thus

it is of great significance to survey the state-of-the-art technologies and study the relevant challenges.Firstly

the basic definition and technical characteristics of zero-power IoT and backscatter communications were presented.Secondly

several typical application scenarios for zero-power backscatter communications in 6G were introduced.Thirdly

the system structure of zero-power backscatter communications was given and the potential key technologies of zero-power backscatter communications for 6G applications were also discussed.Finally

the technical challenges and potential research directions for zero-power backscatter communications were analyzed.Additionally

the proposed overview was of important theoretical significance and practical values for promoting the development of IoT toward full scenes

full spectrum

and many types of services.
