Abstract (in Japanese) (See Japanese page) 
(in English) Wireless Power Transfer (WPT) is a promising technology for powering low-power devices. Efficient and fair energy delivery in multi-user WPT requires appropriate scheduling for resource allocation. In WPT systems, both temporal and spatial power allocation affect performance, motivating spatio-temporal scheduling. This paper proposes a method that jointly optimizes beamforming based on an $alpha$-utility function and time-slot allocation.
