 note = {自動運転の実現には高品質な無線通信が必要であるが，車両が基地局に対して遠方に存在する場合，伝搬損が大きく通信品質が低下してしまう．これまで我々は，遠方車両の信号を他車両を中継し，伝送することで電波の減衰を抑える車車間協調伝送手法を検討してきた．しかし，従来の協調伝送では半二重通信を使用していたため，車両が基地局に直接伝送した場合に比べてスループットが半分となっていた．そこで本稿では，全二重通信を車車間協調伝送に適用することで直接伝送とほぼ同じスループットを有する手法を提案し，計算機シミュレーションにより本手法が優れた伝送効率を有していることを示す．, High-quality wireless communication is indispensable for the realization of autonomous driving. However, when a vehicle is far away from a base station, the communication quality is degraded due to large propagation loss. We have studied a cooperative transmission method between vehicles that suppresses the radio wave attenuation by relaying the signal of the distant vehicle to another closer vehicle for transmission. However, the conventional cooperative transmission method uses half-duplex communication, and the throughput is half of that when vehicles transmit directly to the base station. Therefore, in this paper, we propose a method to apply full-duplex communication to inter-vehicle cooperative transmission, which has almost the same throughput as that of direct transmission, and show that this method has excellent transmission efficiency by numerical simulations.},
