Classification: CPC H | IPC H

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 on the NCB uplink control channel resources, wherein presence of the burst on the NCB uplink control channel resources corresponding to the NCB uplink control channel allocation indicates that the WTRU is requesting uplink shared channel resources, wherein hybrid automatic repeat request (HARQ) feedback is transmitted on the NCB uplink control channel resources via the burst;
monitor a downlink control channel based on transmitting the burst;
receive an uplink shared channel grant on the downlink control channel after transmitting the burst on the NCB uplink control channel resources, the uplink shared channel grant indicating uplink shared channel resource blocks that have been allocated to the WTRU for uplink data transmission; and
transmit the uplink data on the uplink shared channel resource blocks in accordance with the uplink shared channel grant.
