Description
図1及び図2を参照して、本発明の第1の実施形態に係る移動通信システムの構成について説明する。
図3及び図4を参照して、本発明の第1の実施形態に係る移動通信システムの動作、特に、発明の第1の実施形態に係る無線基地局BTSの動作について説明する。
本発明の第1の実施形態に係る移動通信システムによれば、「Time and Rate」方式のEULにおいて、無線基地局NodeBが、現在のスケジューリング対象の移動局UEのバッファが空になった旨を示す「TEBS」を受信する前に、移動局UEのバッファが空になる時刻を予測して、「Zero Grant」を送信することができるため、効率的にスケジューリング対象の移動局UEを切り替えることができる。
