Abstract (in Japanese) (See Japanese page) 
(in English) In wireless power transfer (WPT), transmitting signals from multiple spatially distributed transmitters enables high power transfer efficiency even under signal attenuation caused by obstacles. This article investigates a time-division scheduling method for supplying power to multiple receivers in mult-transmitter WPT systems. Receivers assigned to each transmitter are grouped into clusters, and receivers belonging to different clusters are assigned to the same time slot. Leveraging the property that inter-transmitter interference can enhance received power, we examine slot assignment strategies that exploit inter-cluster interference.
Simulation results demonstrate the effectiveness of considering inter-cluster interference in time-division scheduling for multi-transmitter WPT systems.
