In recent years, 3GPP have standardized series of technologies on IoT (Internet of Things), which achieves the design targets of low cost, low power consumption, massive connection and deep coverage. These IoT technologies can well meet the requirements of diverse scenarios. However, there are still many other scenari – os that require the terminal to have ultra-low power consumption or even zero power consumption, ultra-low cost, very small size etc. With techniques such as RF power harvesting, backscattering and low power computing, zero power communication can well meet these new requirements. Due to its excellent characteristics, zero-power communication is expected to become one important candidate of next generation technology on Internet of Things.
