5Gセルラネットワークのためのミリ波エッジクラウド

近年、インターネットに繋がるデバイスの劇的な増加や様々なアプリケーションの登場により、無線通信容量の将来的な需要はますます増加しています。特に、2020年に5Gシステムが導入されることで、その傾向はますます活発になっています。５Gの典型的な使用ケースとして、eMBB, mMTCやURLLCがあります。また、バックホール側での通信量やend-to-endの遅延の低減が求められます。そのような課題に対応するため、図1で示すような、従来のマクロセル基地局 にミリ波を使用したスモールセル基地局を設置したミリ波オーバーレイヘテロジニアスネットワークを、ここ数年で我々は提案しています。さらには、超広帯域のミリ波通信とマルチアクセスエッジコンピューティング(multi-access edge computing/MEC)を組み合わせた新しい概念も、新たな解決策として提案しています。

The mmWave Edge Cloud system architecture is shown in Fig.2. As an overview of this architecture, the cloud side applications are also deployed on the MEC side according to the application requirements and data traffic situations, and the users are controlled with out-of-band C-plane to be connected to the surrounding MEC application. To reduce the backhaul traffic and end-to-end latency, our architecture could be realized by forwarding (prefetching) data to an edge cloud based on users and network context information such as user position, network load, and data popularity, and enables the network to orchestrate its radio and MEC resources.
