Abstract
【解決手段】リンク方式は、複数のPHICHのインデックスと、制御チャンネル要素(CCE)のインデックス又は物理リソースブロック(PRB)のインデックスと復調基準信号(DMRS)のインデックスの組み合わせとの間で設定される。基地局(BS)は、複数のCCEを用いてユーザー装置(UE)にスケジューリンググラントを伝送する。BSは、リンク方式によって、スケジューリンググラント伝送に使用されるCCEのうちいずれか一つのインデックス又はデータパケット送信に使用されるPRBのうち少なくとも一つのインデックスと伝送されたDMRSのインデックスに基づいて、複数のPHICH内のPHICHのインデックスを決定する。最後に、BSは、決定されたインデックスによって指示されるPHICHを用いてUEに確認応答信号を伝送する。
