| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this research, we propose a novel antenna control method for reducing the number of low throughput User Equipments (UEs) caused by the movement and rotation of High-altitude platform station (HAPS). We assume that each HAPS has three antenna arrays for serving one region that consists of 7 cells and that we know the UE locations in each cell. In the proposed method we first cluster all UEs into three clusters based on the UE locations, each antenna array will be controlled to serve three clusters, respectively. Based on the radius and center location information of three clusters, we can mathematically calculate the antenna parameters by the desired coverage model. We evaluate the proposed method under 5 different UE distribution scenarios. The simulation results show that, in 5 different UE distribution scenarios, the proposed method can reduce the number of UEs with low throughput. Compared with the conventional method, the proposed method can achieve good throughput performance in all the scenarios. |
