Abstract(in English) In MISO (Multiple-Input Single-Output)-based wireless power transfer (WPT) systems, TDM (Time Division Multiplexing) scheduling periodically switches multiple weight vectors for receivers by assigning a time slot to eachweight vector. In this article, we propose a TDM scheduling method using user grouping to achieve efficient and effective WPT. The proposed method clusters receivers with similar channel vectors into a group, and set weight vectors maximizing the harvested power in each group. The lengths of time slots assigned to weight vectors are optimized so as to maximize the minimum harvested power among receivers. We evaluate the performance of the proposed method with simulation experiments in an indoor environment.
