P.1238-6などの伝搬モデルが提案されているが,例えば,WINNERIIモデルでは,マクロ-フェムトセル間の屋外伝搬特性が見通し外の場合は厳密に評価できない場合がある.そこで,本論文では,ヘテロジーニアスネットワークで想定されるセルサイズが300m以内における屋外-屋外間,屋外-屋内間,屋内-屋内間の電界強度測定を実施する.得られた測定結果より,伝搬損,屋内侵入損/屋内区間における伝搬損,短区間中央値の標準偏差について,WINNERII(屋外,屋外-屋内)/ITU-R P.1238-6(屋内)モデルとの比較を行い,WINNERII/ITU-R P.1238-6モデルと測定結果を用いて,干渉量評価に関するケーススタディを行う.マクロ-フェムトセル間における干渉量として,Signal to Interference plus Noise power Ratio(SINR)特性を評価する.従来モデルに実験で得られた結果を組み合せることで,従来モデルで厳密にカバーできない範囲である,フェムト-マクロセル間の屋外見通し外伝搬特性及び屋内侵入伝搬損を評価できるとともに,これらのパラメータがSINR特性に与える影響が大きいことを明かにする.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"42124","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishimori,
