1. A wireless transmit/receive unit (WTRU) comprising a processor configured to:
- receive a first allocation from an evolved Node B (eNB), wherein the first allocation is an allocation of a non-contention based (NCB) uplink control channel, the first allocation comprises a configuration for transmitting scheduling requests (SRs) over the NCB uplink control channel, and the configuration indicates a periodicity allocated to the WTRU for transmitting scheduling requests on the NCB uplink control channel and indicates which sub-carrier resources of the NCB uplink control channel are to be used by the WTRU for transmitting the scheduling requests;
transmit a scheduling request over the NCB uplink control channel in accordance with the first allocation, wherein the transmitted scheduling request comprises a transmission burst, and presence of the transmission burst on NCB uplink control channel resources assigned to the WTRU by the first allocation is indicative of a request for uplink transmission resources by the WTRU;
monitor a downlink control channel;
detect that a transmission intended for the WTRU on the downlink control channel is intended for the WTRU based on a WTRU identifier indicated in the transmission on the downlink control channel, wherein the transmission on the downlink control channel comprises a second allocation, the second allocation being an allocation of an uplink shared channel; and
transmit data over the uplink shared channel in accordance with the second allocation.

Abstract
In a wireless communication system comprising at least one evolved Node-B (eNB) and a plurality of wireless transmit/receive units (WTRUs), a non-contention based (NCB) channel is established, maintained, and utilized. The NCB channel is allocated for use by one or more WTRUs in the system for utilization in a variety of functions, and the allocation is communicated to the WTRUs. The wireless communication system analyzes the allocation of the NCB channel as required, and the NCB channel is reallocated as required.
