A method implemented by a wireless transmit/receive unit, WTRU, the method comprising the steps of: receiving an allocation of a non-contention based, NCB, uplink control channel from an evolved Node B, eNB, wherein the NCB uplink control channel is used by the WTRU for transmitting a plurality of types of uplink control information, wherein NCB uplink control channel resources are a combination of time multiplexed, frequency multiplexed, and code multiplexed, wherein the allocation comprises a configuration for transmitting scheduling requests over the NCB uplink control channel, and wherein the configuration indicates a periodicity assigned to the WTRU for transmitting scheduling requests on the NCB uplink control channel; transmitting a burst over the NCB uplink control channel in accordance with the allocation of the NCB uplink control channel, wherein presence of the burst on the NCB uplink control channel is indicative of a request for uplink transmission resources by the WTRU; monitoring a downlink control channel based on transmitting the burst over the NCB uplink control channel; detecting that a transmission 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 an allocation of an uplink shared channel, and wherein the allocation of the uplink shared channel explicitly indicates which resource blocks of the uplink shared channel have been assigned to the WTRU for transmitting data; and transmitting the data over the uplink shared channel in accordance with the allocation of the uplink shared channel. receiving an allocation of a non-contention based, NCB, uplink control channel from an evolved Node B, eNB, wherein the NCB uplink control channel is used by the WTRU for transmitting a plurality of types of uplink control information, wherein NCB uplink control channel resources are a combination of time multiplexed, frequency multiplexed, and code multiplexed, wherein the allocation comprises a configuration for transmitting scheduling requests over the NCB uplink control channel, and wherein the configuration indicates a periodicity assigned to the WTRU for transmitting scheduling requests on the NCB uplink control channel; transmitting a burst over the NCB uplink control channel in accordance with the allocation of the NCB uplink control channel, wherein presence of the burst on the NCB uplink control channel is indicative of a request for uplink transmission resources by the WTRU; monitoring a downlink control channel based on transmitting the burst over the NCB uplink control channel; detecting that a transmission 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 an allocation of an uplink shared channel, and wherein the allocation of the uplink shared channel explicitly indicates which resource blocks of the uplink shared channel have been assigned to the WTRU for transmitting data; and transmitting the data over the uplink shared channel in accordance with the allocation of the uplink shared channel.
