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.
Claims19
A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- determining that there is uplink data to be transmitted;
- transmitting a scheduling request over a non-contention based (NCB) uplink control channel based on determining that there is uplink data to be transmitted;
- monitoring a downlink control channel based on transmitting the scheduling request 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
- transmitting the uplink data over the uplink shared channel in accordance with the allocation of the uplink shared channel received on the downlink control channel.
A device comprising a processor and memory, the processor and memory configured:
- receive a scheduling request over a non-contention based (NCB) uplink control channel, the scheduling request being received on resources of the NCB uplink control channel that were assigned to a WTRU;
- determine that the WTRU has uplink data to be transmitted based on receiving the scheduling request on resources of the NCB uplink control channel that were assigned to a WTRU;
- send a transmission on a downlink control channel that is intended for the WTRU based on receiving the scheduling request, wherein a WTRU identifier indicated in the transmission on the downlink control channel indicates that the transmission on the downlink control channel is intended for the WTRU, and the transmission on the downlink control channel comprises an allocation of an uplink shared channel;
- and
- receive the uplink data over the uplink shared channel in accordance with the allocation of the uplink shared channel sent on the downlink control channel.
