Abstract
Description
[数式1]
ROT=I_0/N_0
図2を参照すれば、基地局と端末は、202段階で、E−DCHを設定する。前記202段階の設定過程は、専用伝送チャネル(dedicated transport channel)を通じたメッセージの伝達過程を含む。E−DCHの設定が行われれば、端末は、204段階で、基地局にスケジューリング情報を通知する。前記スケジューリング情報は、逆方向チャネル情報を示す端末送信電力情報、端末が送信することができる余分の電力情報、端末のバッファーに積もっている送信すべきデータの量などになることができる。
図4では、ダウンリンクキャリア#1 403からSC−HSUPA端末が既に30名をサービスしている状態であるとしても(401)、ダウンリンクキャリア#1の余分の10個の資源402及びダウンリンクキャリア#2の余分の40個の資源404、405がすべてDC−HSUPA端末をサポートすることができる。したがって、この場合、サポート可能なDC−HSUPA端末は、25(=(10+40)/2)個になる。
