Description
(式1) SFN mod n = i
を用いる。ここで、mod nはモジュロn関数である。一つの例では、式2、すなわち、
(式2) SFN mod 8 = i
で示されるモジュロ8関数を用いる。その結果、図3に示すとおり、時間スロット3の中の最初のフレーム440でサブチャネル0を割り当てる。2番目のフレーム441ではサブチャネル1を割当て、8番目のフレーム447、すなわちサブチャネル7を割り当てる8番目のフレーム447まで、以下同様に割り当てる。サブチャネルの数は8、4、2または1とするのが好ましい。図3は時間スロット3へのサブチャネル割当てだけを示しているが、同じ手法を任意の時間スロット番号に用いる。
