Description
本出願は、2009年8月12日に出願された米国特許仮出願第61/233,359号明細書、および2009年8月13日に出願された米国特許仮出願第61/233,736号明細書の利益を主張するものであり、その内容を参照により本明細書に組み込む。
PCB_PUSCH(i)=min{PCMAX、10log10(MPUSCH(i))+PO_PUSCH(j)+α(j)・PL+ΔTF(i)} 式(1)
式中、
PCMAXは、MIN{PEMAX、PUMAX}として定義される構成されたWTRU送信電力、ただし、PEMAXは、高位のレイヤにより構成された最大の許容電力であり、PUMAXは、指定されたWTRU電力クラスに対する最大のWTRU電力である。
MPUSCH(i)は、サブフレームiで有効なリソースブロックの数で表されたCB−PUSCHリソース割当ての帯域幅である。
PO_PUSCH(j)は、j=0および1に対する高位のレイヤから提供されるセルの特定の公称成分(nominal component)PO_NOMINAL_PUSCH(j)と、WTRUの特定成分PO_UE_PUSCH(j)との合計からなるパラメータである。CB−PUSCHに対して、PO_UE_PUSCH(j)の新しいタイプ(すなわち、j=3に対するもの)を定義することができる。
ΔTF(i)は、CB−PUSCHに対して使用されるMCSに従って送信電力を補償する。
PLは、高位レイヤにより提供されたRS(基準信号)電力、および受信したRS電力に基づいてWTRUで計算されたダウンリンクの経路損失推定である。
α(j)は、高位レイヤから提供されるセル特有のパラメータである。
1.コンテンションベースのアップリンクチャネルで送信するための無線送受信ユニットにより実施される方法であって、
少なくとも1つのコンテンションのないアップリンクチャネルアロケーションが許可されているという条件で、アップリンク送信に対して少なくとも1つのコンテンションのないアップリンクチャネルアロケーションを使用することを試みる、コンテンションベースのアップリンクチャネルへのアクセスのルールベースの制限を適用するステップ
