Description
スクランブリングの2つの動作から構成される。チャネル化は、各データ記号を多数のチップ(またはビット)に変換し、信号の帯域幅を増大する。データ記号あたりのチップの数は拡散因子(SF)と呼ばれる。スクランブリング動作において、スクランブリングコードは、拡散信号に適用される。
HS−DPCCH上に仮定される。PARはIまたはQブランチ上にマッピングされるHS−DPCCHおよびすべてのSF=256チャネル化コードに対して測定される。
図8は上に詳述したようなチャネル構成を実施するための装置を図解する。利用可能なコード、すなわち、他の物理チャネルによって使用されないコードは、最適コードを決定するために、送信対選択装置702に供給される。さらに、PAR解析情報は送信対選択装置702に供給される。この装置は、専用チャネルを処理する変調パスを決定する。変調パスまたはブランチは、セレクター704に対する制御として供給される。セレクター704は、またDPCCH信号も受信する。この信号は、送信対選択装置702からの制御信号に応答してIブランチまたはQブランチに送られる。
