Description
本出願は、本明細書で完全に説明されたかのように参照によって組み込まれる、2008年10月31日に出願された米国特許仮出願第61/109,978号明細書、2008年11月24日に出願された米国特許仮出願第61/117,494号明細書、2008年11月25日に出願された米国特許仮出願第61/117,851号明細書、2008年12月30日に出願された米国特許仮出願第61/141,638号明細書、および2009年1月30日に出願された米国特許仮出願第61/148,690号明細書の優先権を主張する。
(2)あるいは、第2のアップリンク搬送波におけるハッピービットは、もっぱら第2のアップリンク搬送波における(またはもっぱら第1のアップリンク搬送波における)グラントおよび電力ヘッドルームの状態を考慮して、ハッピービット決定のための従来の規則によって設定することができる。
then TPCはアップリンク搬送波1用
Else TPCはアップリンク搬送波2用
例えば、アップリンク搬送波1 520のための電力制御コマンドは、無線スロット#0、2、4、6、8、10、12、および14で搬送することができ、一方、アップリンク搬送波2 540のための電力制御コマンドは、無線スロット#1、3、5、7、9、11、および13で搬送することができ、またはこれの反対である。あるいは、アップリンク搬送波1 520には、アップリンク搬送波2 540よりも多くの電力制御コマンドを割り当てることができる。例えば、アップリンク搬送波1 520のための電力制御コマンドは、無線スロット#0、1、3、4、6、7、9、10、12、および13で搬送することができ、一方、アップリンク搬送波2 540のための電力制御コマンドは、無線スロット#2、5、8、11、および14で搬送することができる。この代替形態は、より多くの電力制御コマンドを提供することで、全体的な効率が向上する理由が存在する場合に、使用することができる。そのようなシナリオは、例えば、アップリンク搬送波1 520が、アップリンク搬送波2 540よりも多くの物理層チャネルを搬送している場合とすることができる。
本明細書で説明されるこれらの実施形態では、WTRUは、データを送信する必要がないと決定された場合、DPCCHを送信しないように構成することができる。WTRUは、最大電力が搬送波毎に割り当てられるときに、十分な電力を有さない場合、第2の搬送波上でいかなるデータも送信しないように構成することもできる。例えば、搬送波の一方が十分な電力を有さない場合、WTRUは、最小セットのE−TFCIを使用する代わりに、一方の搬送波(最も大きなUPHまたは最も大きなNRPMを有する搬送波)を使用して、送信を行うことができ、またはその代わりに、WTRUは、両方が十分な電力を有さない場合、搬送波の一方において送信を行うことができない。WTRUは、搬送波の一方において最小セットを使用することができ、第2の搬送波上では送信を行うことができない。
