Abstract:
1. A wireless transmit/receive unit (WTRU) that controls power offset of at least one downlink (DL) enhanced uplink (EU) channel comprising: an enhanced dedicated channel (E-DCH) channel; an uplink (UL) enhanced uplink (EU) channel; a downlink (DL) enhanced uplink (EU) channel; wherein the WTRU sends, via a transmitter, an E-DCH allocation request via one of the E-DCH channel or UL EU channel; wherein, in response to the E-DCH allocation request, the WTRU monitors the DL UE for the channel allocation information receipt via the WTRU antenna; wherein on a condition that a measurement regarding the UL EU channel meets a predetermined threshold, the DL EU transmission power offset is adjusted, wherein the measurement is made by subtracting a number of EU media access control (MAC-e) failures of the WTRU reported by the WTRU from a number of MAC-e failures of the WTRU reported by a Node-B.
