Description
例1
第1の例では、RFとQとはNuだけに従って適応制御される。さらに、RFとQとの適応制御は、以下の目的に従って実行される。つまり、全ユーザの間の直交性が維持され、アクティブな副搬送波数が最大限にされる。SFは、送信されたデータの冗長性を調整するためにも適応制御される。
第2の例では、RFとQとは、NuとWの両方に従って適応制御される。さらに、RFとQとの適応制御は以下の目的に従って実行される。つまり、全ユーザ間の直交性が維持され、アクティブな副搬送波の総数が最大限にされ、一人のユーザに割り当てられるアクティブな副搬送波の数がユーザによって要求される副搬送波の数に比例する。SFも、送信されたデータの冗長性を調整するために適応制御される。
