Abstract
In a wireless communication system comprising at least one evolved Node-B (eNB) and a plurality of wireless transmit/receive units (WRTUs), 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.
Claims39
A method for a wireless transmit/receive unit (WTRU), the method comprising:
- receiving a first allocation, 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, the configuration comprises a periodicity and an indication of dedicated physical resources allocated to the WTRU for transmitting the SRs, and the NCB uplink control channel is comprised of allocated physical resources that are time multiplexed such that given frequency resources of the NCB uplink control channel may be used by different WTRUs for transmitting control signaling at different instances of time;
- transmitting a transmission burst over the NCB uplink control channel in accordance with the first allocation, wherein the presence of the transmission burst on resources dedicated to the WTRU by the first allocation is indicative of a request for uplink transmission resources by the WTRU;
- monitoring a downlink control channel for a shared channel resource allocation;
- detecting a transmission intended for the WTRU on the downlink control channel, wherein the transmission comprises a second allocation and the second allocation is an allocation of an uplink shared channel;
- and
- transmitting data over the uplink shared channel in accordance with the second allocation.
