摘要
Towards Beyond 5G/6G, factory automation, digital twin, and cyber-physical systems (CPS) are expected to be realized. Internet of Things (IoT) technology for sensing a variety of data in the real world will be necessary to realize these systems. As the number of IoT sensors increases, it becomes a major challenge to deliver power wirelessly to IoT sensors. We propose a communication and Wireless Power Transfer (WPT) system that performs WPT by beamforming from a base station to an IoT sensors in order to supply stable and sufficient power. In previous studies, beam control according to the IoT terminal at the base station is difficult because IoT terminal information is not fed back to the base station. In this study, we develop a communication and WPT system that includes feedback of IoT terminal information to the base station, and demonstrate beam control according to IoT terminal information at the base station.
