Abstract
【解決手段】マーカの電力レベルが異なることにより、基地局(110)はエラー確率の低い代替基準を使用して、リクエスト・マーカを識別できる。ここで、代替基準には、マーカをそれぞれのエネルギ・レベルしきい値と比較することと、タイム・スロットの占有状態、相互に排他的なコード・チャネルの占有状態またはこれらの組み合わせを監視することとを含むことができる。例えば、ある特定の実施形態では、一般には優先度の高いマーカであるリクエスト・マーカが、高電力で伝送され、これによりリクエスト・マーカの検出確率を向上し、誤り検出の確率を低減させる。
【選択図】図2
Description
シミュレーションでは、ハートビート(HB)およびリクエスト付きハートビート(HB/RQST)チャネルの検出および誤り検出の確率に影響する信号交換の説明を最初に提示する。HBおよびHB/RQSTチャネルに対して推奨されるSNR目標を提供する。さらに、分析計算を行って、許容できる検出確率および誤り検出確率の推奨される目標E/Ioを判断する。
i番目のユーザのSNRは、SNR(i)=P(i)−P_interference+処理利得+Erとして計算される。ここで、P_interference(i)(P_干渉(i))はi番目のユーザが受信した干渉の全てであり、P_interference(i)=20*log10(10)^Σj≠i(10^P(j)/20)+10^(PTH/20))として計算され、またP(i)はi番目のユーザから受信した電力であり、PTHは熱雑音下限であり、任意に120dBmに設定される;
処理利得は10log64である;
フェージング・モデルはJakesである;
Er=BTSにおけるSNR推定のエラーであって、1σ=0.67dBの正規分布ランダム変数である;
電力制御ビット(PCB)エラー=3%
=5%*0.1%=5E−5 (2)
ここで、Pfdは誤り検出の確率であり、Pdは検出の確率である。
