Abstract
【解決手段】本発明に係る無線基地局BTSは、スケジューリング対象の移動局UEによって通知されたTEBSに基づいて、移動局UEのバッファが空になる時刻を予測するように構成されている予測部13と、移動局UEに対して、予測された時刻に基づいて、E-DPDCHを介したデータ信号の送信を停止するように指示する「Zero Grant」を送信するように構成されている送信部15とを具備する。
【選択図】図3
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。
