Abstract
A method and apparatus for No-TX mode for a wireless transmit/receive unit (WTRU) and Node B that suspends the transmission of power control updates and associated signaling over dedicated uplink and downlink channels. Triggers and signals between the WTRU and Node B to activate and disable No-TX mode. A radio link is re-established to resume data transmission when No-TX mode is disabled, and data may also be transmitted during defined transmission opportunities while in No-TX mode.
Claims10
A method for use in a wireless transmit/receive unit (WTRU) in an idle mode for transmitting over an enhanced dedicated channel (E-DCH), the method comprising:
- determining a power transmission level for a transmission burst;
- transmitting the transmission burst at the determined power transmission level;
- receiving an acquisition indication and a resource assignment from a Node B in response to the transmission burst, wherein the resource assignment includes an assigned E-DCH resource;
- transmitting data using the assigned E-DCH resource;
- and
- releasing the assigned E-DCH resource on a condition that the WTRU receives a release command from the Node B on an E-DCH Absolute Grant Channel (E-AGCH).
A wireless transmit/receive unit (WTRU) in an idle mode configured to transmit over an enhanced dedicated channel (E-DCH), the WTRU comprising:
- a processor configured to determine a power transmission level for a transmission burst;
- a transmitter configured to transmit the transmission burst at the determined power transmission level;
- a receiver configured to receive an acquisition indication and a resource assignment from a Node B in response to the transmission burst, wherein the resource assignment includes an assigned E-DCH resource;
- the transmitter configured to transmit data using the assigned E-DCH resource;
- and
- the processor, the transmitter, and the receiver configured to release the assigned E-DCH resource on a condition that the WTRU receives a release command from the Node B on an E-DCH Absolute Grant Channel (E-AGCH).
