1. A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- transmitting a channel acquisition request to a Node B while the WTRU is in a CELL_FACH state;
receiving a resource assignment from the Node B while the WTRU is in the CELL_FACH state, wherein the resource assignment includes an assignment of an Enhanced Dedicated Channel (E-DCH) resource;
communicating using the assigned E-DCH resource while the WTRU is in the CELL_FACH state; and
releasing the E-DCH resource while the WTRU is in the CELL_FACH state.

Abstract
A method and apparatus for requesting and releasing resources for a wireless transmit/receive unit (WTRU) and/or Node B. The WTRU may transmit a channel acquisition request to the Node B and receive a resource allocation from the Node B. The resource allocation may include a common resource. The WTRU may release the common resource. The release may be based on one or more conditions. The channel acquisition request or the resource allocation may include information related to one or more channels or resources.
