Claim 9:
10. A wireless transmit/receive unit (WTRU) comprising a processor configured to:
receive a control message that provides a non-contention based (NCB) uplink control channel allocation, wherein the control message indicates a periodicity, sub-carrier resources, and code information associated with NCB uplink control channel resources allocated to the WTRU for transmitting requests for uplink shared channel resources;
transmit a burst comprising control information on the NCB uplink control channel resources, wherein presence of the burst on the NCB uplink control channel resources indicates that the WTRU is requesting uplink shared channel resources, and the control information comprises hybrid automatic repeat request (HARQ) feedback;
receive a transmission associated with a WTRU identifier on a downlink control channel, wherein the transmission on the downlink control channel comprises an uplink shared channel grant; and
transmit data on the uplink shared channel in accordance with the uplink shared channel grant.
