Abstract
A method and apparatus for pre-allocating uplink resources in CELL-FACH are disclosed. A wireless transmit/receive unit (WTRU) in CELL_FACH or CELL_PCH states may be pre-allocated with an uplink resource when a downlink transmission is transmitted. The WTRU may then use the pre-allocated uplink resource for channel quality information or hybrid automatic repeat request (HARQ) feedback, or any other purposes. The pre-allocated uplink resource may be enhanced dedicated channel (E-DCH) resource or high speed dedicated physical control channel (HS-DPCCH) resource.
