| Outline of Final Research Achievements |
Fiber Wireless systems, which integrate heterogeneous wireless access networks into a passive optical network (PON), are considered a promising option for Beyond 5G technology to realize ultrahigh-speed, low-latency, and high-density communications.In the Fiber Wireless system, optical bandwidth allocation and radio frequency control functions are organically linked to achieve high-quality communications. In this study, we compared each technology and proposed an integrated FiberWireless access network that dynamically reconfigures the optical and wireless frequency and communication allocation functions. We confirmed that the proposed network dramatically improves the quality of communication services in a Beyond 5G environment with a wide variety of terminals and services.

Beyond 5G通信システムでは時間的・空間的に異なる通信要求が発生した場合，臨機応変的な対応が必要不可欠である．従来のFiber Wirelessシステムでは，状況の変化に適応するための動的設計理論が確立されておらず，複雑な環境に対応可能な新しい通信方式の実現が望まれている．本研究では，Beyond 5G通信システムが状況の変化を認識する機能，状況毎に通信要求特性を推定する機能，供給能力を算出する機能を体系的に統合することで動的設計理論の確立を目指した．更に本理論を実装することで，光と無線の周波数・通信機能構成を最適な状態にすることが可能となり，幅広い無線通信サービスの高品質化に寄与した．
