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.
Claims18
A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:
- receiving first configuration information, the first configuration information indicating a first allocation for non-contention based (NCB) uplink control channel transmissions in a first cell, the first allocation indicating a first periodicity and first resources allocated to the WTRU for the NCB uplink control channel transmissions in the first cell;
- transmitting first control information via the first cell in accordance with the first allocation;
- receiving a shared channel transmission via the first cell, the shared channel transmission comprising an indication to handover from the first cell to a second cell, the shared channel transmission indicating a second allocation for NCB uplink control channel transmissions in the second cell, the second allocation indicating a second periodicity and second resources allocated to the WTRU for the NCB uplink control channel transmissions in the second cell;
- and
- transmitting second control information via the second cell in accordance with the second allocation comprised in the shared channel transmission received via the first cell.
A wireless transmit/receive unit (WTRU) comprising a processor and memory, the processor and memory configured to:
- receive first configuration information, the first configuration information indicating a first allocation for non-contention based (NCB) uplink control channel transmissions in a first cell, the first allocation indicating a first periodicity and first resources allocated to the WTRU for the NCB uplink control channel transmissions in the first cell;
- transmit first control information via the first cell in accordance with the first allocation;
- receive a shared channel transmission via the first cell, the shared channel transmission comprising an indication to handover from the first cell to a second cell, the shared channel transmission indicating a second allocation for NCB uplink control channel transmissions in the second cell, the second allocation indicating a second periodicity and second resources allocated to the WTRU for the NCB uplink control channel transmissions in the second cell;
- and
- transmit second control information via the second cell in accordance with the second allocation comprised in the shared channel transmission received via the first cell.
