無線LANの制御情報であるビームフォーミングフィードバック（BFF）は、固有モード伝送のためにチャネル状態情報（CSI）から計算されるものであり、環境の変化に対してインフォマティブである。このため、CSIに基づくセンシングや、BFFに基づくセンシングが検討されてきたが、特に後者は教師データを必要とする機械学習ベースのものが多く、教師データを観測できない場合には有用ではないと考えられてきた。一方で、研究代表者らのこれまでの研究により、傍受したBFFにより機械学習なしに人の呼吸数推定などが可能である一方、プライバシ漏洩リスクをはらんでいることが明らかになっている。
2024年度は、BFFのどの要素がセンシング特徴量として重要なのかという観点で、以下の2つの研究成果をあげた。
BFFには、サブキャリア毎のCSI行列を特異値分解した右特異行列Vと、全サブキャリアで平均化した特異値である平均ストリームSNR（AS-SNR）という多数の要素が含まれている。右特異行列Vが有する物理的情報を明らかにするため、2×2 MIMO CSIに対応するBFFフレームに格納されている右特異行列Vが、CSIの要素から、数値計算ではなく記号計算で求められることを明らかとした。
次に、BFFに含まれるどの要素がセンシング特徴量として重要かを検討した。具体的にはAS-SNRを、無線LANセンシングの評価指標として有望なセンシングSNR（SSNR）を用いて分析した。その結果、最終ストリームのAS-SNRが、すべてのストリームの中で最も低いSNRを持つ一方で、SSNRの観点からは優れた特徴量であることが明らかとなり、呼吸数推定においてもこの仮説を支持する実験結果が得られた。 -

2023年度において、我々はWi-Fiの通信信号を活用した画像推定技術「RF-Inpainting」の高度化に焦点を当てました。この技術は、無線通信信号に内包される電波伝搬環境の情報、すなわち、空間内のどこに壁や天井や人のような反射や回折させる物体が存在するか、という物理的トポロジに関する情報をもとに監視カメラ等の画像を復元・修復する技術です。2023年度はWi-Fi CSI（Channel State Information）と呼ばれる、より詳細な無線チャネル情報を用いた手法を提案し、さらに高精度なイメージングが可能であることを実験的に示しました。この研究の成果はIEEEの学術誌に投稿中です。
<BR>
また、無線環境センシングにおけるCSIのコンセプトシフトに関しても実験的に検証を行いました。コンセプトシフトは時間経過とともにデータの分布が変化することであり、Wi-Fiセンシングの精度に影響を与えることが実験的に確認されました。さらに、異なるCSI測定機器や方法によってコンセプトシフトの発生強度が異なることを実証しました。この研究成果もIEEE論文誌に投稿準備中です。
<BR>
加えて、Firmware-AgnosticなWi-Fiセンシング技術の発展に寄与する特徴量選択手法を開発しました。Wi-Fi CSI測定には通常特殊なファームウェアが必要ですが、我々の提案する手法では、どのような測定器を使用しても測定が可能となり、普及の障壁を低減します。この技術はIEEE Communication Letterに採択され、その優れたアプローチが認められています。 -

リアルタイム情報共有は，近未来における多様な情報通信アプリケーションを支える最重要機能の一つであると目されている.リアルタイム情報共有の性能評価には遅延時間を始めとする従来の性能指標では不十分であることが知られており，その解決のために近年導入されたのが Age of Information (AoI) の概念である. AoI は情報鮮度を定量化する指標であり，その応用性への高い期待から，最近では活発な研究が国際的に行われ始めている.しかし，AoI の概念を実際のアプリケーションへ応用する上で，「AoI の目標値をいかに客観的かつ合理的に定めるか」という本質的な課題に対し，十分な知見が未だ得られていない.本研究課題は，俯瞰的な理論研究と実際的な応用研究を並行して実施し，それらの成果を統合することにより，多様なシステムへ適用可能な形でこの問題の解決に取り組むことを目的とする.
本年度は，応用研究の題材として，水中画像伝送システム，車載スモールセルネットワーク，クラウドゲーミングシステム，ならびに人工知能 (AI) エッジ推論システムを取り上げ，これらのシステムの数理モデル化と解析を実施した．特に，水中画像伝送システムについては通信における物理層レベルからのモデル化に加え，深層学習に基づいて情報源・通信路結合符号化と変調を一括化する新たな手法を具体的に検討した．
また，理論研究については，離散集合ならびに連続値集合上に値を取る二種類の連続時間確率過程について，AoI とモニタリング精度を結びつける定式化ならびに諸量の特徴づけを行った． -

The objective of this research is to predict wireless communication quality from visual data (e.g., images) from cameras and radar. In wireless communications, especially those using ultra-high frequency bands such as millimeter wave communications, visible light communications, and terahertz communications, pedestrians, cars, buildings, and roadside trees become obstructions and reflections, which greatly affect the wireless communication quality. In this research, we established a technique to accurately predict wireless communication quality 0.5 to 1 second ahead based on spatio-temporal information contained in the vision data from cameras, radar, and LiDAR.

The purpose of this research is to solve the line-of-sight (LoS) blockage problem in millimeter-wave (mmWave) communications by utilizing spatiotemporal information for realizing a highly reliable wireless communication network. In particular, by applying machine learning, the quality of mmWave communications (e.g., the received power and throughput in several hundred milliseconds ahead) is predicted accurately and directly from RGB and depth images that contain 3D spatial information. In addition, we have established proactive control mechanisms that improve the communication quality of mmWave communications.
