Abstract (in Japanese) (See Japanese page) 
(in English) The use of unmanned aerial vehicle (UAV) networks at backhaul networks for ground-based communications is being considered to enable high-speed and high-capacity communications. However, due to the increase in terminal density and other reasons, there is a high possibility that interference between the same channels can occur, and communication requirements cannot be met. Therefore, in this paper, we propose a joint optimization of the location of UAVs and the allocation of communication resources using C-OFDMA (Coordinated-Orthogonal Frequency Division Multiple Access) to efficiently avoid interference and increase the capacity of each terminal. C-OFDMA is one of the interference avoidance techniques that is likely to be implemented in IEEE802.11be. Hence, we construct a model that represents the capacity of the communication channel in an UAV network. In the proposed model, we analyze the changes in communication capacity with respect to the changes in the position of the UAV and the patterns of communication resource allocation. Based on this model, we derive the optimal position of the UAV and the resource allocation patterns. In this paper, we perform simulations to verify the improvement of the communication channel capacity using proposed model.
