Abstract

A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

First claim

What is claimed is:

1. A wireless transmit/receive unit (WTRU) comprising:
a transceiver; and
a processor, wherein
the transceiver and the processor are configured to receive pre-allocated uplink (UL) resource sets indicating radio resources for uplink transmission;
the processor is configured to determine, using the pre-allocated UL resource sets, resource blocks for a periodic transmission of data, wherein each of the resource blocks has a plurality of subcarriers; and
the transceiver and processor are configured to send the periodic transmission of the data using the determined resource blocks, wherein the data includes control information.

2. The WTRU of claim 1 , wherein the transceiver and the processor are configured to receive a signal from a base station prior to the periodic transmission of the data using the determined resource blocks.

3. The WTRU of claim 1 , wherein the pre-allocated UL resource sets are stored as a table.

4. The WTRU of claim 1 , wherein the transceiver and the processor are configured to send the periodic transmission of the data using the determined resource blocks in sub-frames.

5. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving pre-allocated uplink (UL) resource sets indicating radio resources for uplink transmission;
determining using the pre-allocated UL resource sets, resource blocks for periodic transmission of data, wherein each of the resource blocks has a plurality of subcarriers; and
sending the periodic transmission of the data using the determined resource blocks, wherein the data includes control information.

6. The method of claim 5 , comprising receiving a signal from a base station prior to the periodic transmission of the data using the determined resource blocks.

7. The method of claim 5 , wherein the pre-allocated UL resource sets are stored as a table.

8. The method of claim 7 , comprising sending the periodic transmission of the data using the determined resource blocks in sub-frames.
