Research Abstract

本研究では,基地局での利用可能通信路状態情報に応じて通信路状況の良いユーザセットを選択し,情報を送信する(スケジューリングする)ことで,高いスループットを達成するマルチユーザMultiple-Input Mu ; tiple-Output(MIMO)方式について検討した.基地局での利用可能通信路状態情報は,通信路の状態が変化する時変環境では,各ユーザから基地局へのフィードバック遅延のため,ユーザからのフィードバック情報と基地局から送信時の通信路状態とは異なる.そのため,時変環境では高いスループットは得られない.今年度はユーザのサービス要求と通信品質に基づくユーザ選択及び電力割り当て法を提案した.提案法を理論及び計算機シミュレーションにより評価し,少ないフィードバック情報量でも高いスループット及び異なるサービス品質を達成できることを示した.
