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.
