First Claim
Patent Images
1. A method for pre-allocating a resource for uplink transmission, the method comprising:
- a wireless transmit/receive unit (WTRU) receiving a high speed downlink channel (HS-DSCH) transmission while in one of a CELL_FACH and CELL_PCH state;
the WTRU receiving a downlink message including a pre-allocated index to an uplink resource; and
the WTRU transmitting uplink transmission and uplink feedback information using the pre-allocated uplink resource.

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.
