Claim 0:
1. A method implemented by wireless transmit/receive unit (WTRU) for obtaining low latency access to an uplink shared channel, the method comprising:
receiving 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;
transmitting 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 coincides with the burst transmitted on the NCB uplink control channel resources;
monitoring a downlink control channel based on transmitting the burst;
receiving a transmission associated with a WTRU identifier on the downlink control channel, wherein the transmission on the downlink control channel comprises an uplink shared channel grant; and
transmitting data on the uplink shared channel in accordance with the uplink shared channel grant.
