Claim:
1. A method for power scaling in a wireless transmit/receive unit (WTRU) configured for operation on multiple carriers comprising: selecting a carrier from the multiple carriers in response to the WTRU having exceeded a predetermined value, wherein the predetermined value is a maximum allowed transmit power for the WTRU, wherein each carrier has a plurality of channels, wherein the selected carrier from the multiple carriers is associated with an Enhanced Dedicated Channel (E-DCH) and the selected carrier is a carrier having a highest Dedicated Physical Control Channel (DPCCH) power of the multiple carriers; and applying power scaling to any E-DCH Dedicated Physical Data Channels (E-DPDCHs) in the selected carrier; and on a condition that the power scaling in the selected carrier is applied and in response to the WTRU still having exceeded the predetermined value, applying power scaling on other carriers of the multiple carriers based on DPCCH power levels of the other carriers; and on a condition that the power scaling in the other carriers is applied and in response to the WTRU still having exceed the predetermined value, applying further power scaling to at least one of the multiple carriers such that a power ratio between the DPCCH and other control channels of the at least one carrier is maintained and a power ratio between the DPCCH and any E-DPDCHs of the at least one carrier is maintained.
