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.

Claims (34)

1. A wireless transmit/receive unit (WTRU) comprising:

a transceiver; and

a processor, wherein the transceiver and the processor are configured to:

receive, from a network node, layer 1/layer 2 (L1/L2) control information, wherein the L1/L2 control information indicates, for a new dynamic allocation of resources for the WTRU, a frequency domain resource allocation, frequency hopping information, and repetition information; and

transmit, to the network node, uplink data according to the L1/L2 control information.

2. The WTRU of claim 1 , wherein the transceiver and the processor are further configured to:

receive, from the network node, layer 3 (L3) control information including radio resource allocation information for uplink data transmission, in order to reduce L1/L2 control channel overhead.

3. The WTRU of claim 2 , wherein the L3 control information indicates periodicity information, duration information, and sequence information.

4. The WTRU of claim 2 , wherein the L3 control information is radio resource control (RRC) control information.

5. The WTRU of claim 2 , wherein at least some of the received L1/L2 control information overrides the received L3 control information.

6. The WTRU of claim 1 , wherein the uplink data is transmitted periodically according to the L1/L2 control information.

7. The WTRU of claim 1 , wherein the transceiver and the processor are further configured to:

receive, from the network node, second L1/L2 control information indicating a deallocation of the allocation of resources.

8. The WTRU of claim 1 , wherein the transceiver and the processor are further configured to:

transmit, to the network node, an acknowledgement message in response to the received L1/L2 control information.

9. The WTRU of claim 1 , wherein the transceiver and the processor are further configured to:

determine parameters for the uplink data transmission based on a locally stored table.

10. The WTRU of claim 1 , wherein the L1/L2 control information is received in an orthogonal frequency division multiple access (OFDMA) format.

11. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

receiving, from a network node, layer 1/layer 2 (L1/L2) control information, wherein the L1/L2 control information indicates, for a new dynamic allocation of resources for the WTRU, a frequency domain resource allocation, frequency hopping information, and repetition information; and

transmitting, to the network node, uplink data according to the L1/L2 control information.

12. The method of claim 11 , further comprising:

receiving, from the network node, layer 3 (L3) control information including radio resource allocation information for uplink data transmission, in order to reduce L1/L2 control channel overhead.

13. The method of claim 12 , wherein the L3 control information indicates periodicity information, duration information, and sequence information.

14. The method of claim 12 , wherein the L3 control information is radio resource control (RRC) control information.

15. The method of claim 12 , wherein at least some of the received L1/L2 control information overrides the received L3 control information.

16. The method of claim 11 , wherein the uplink data is transmitted periodically according to the L1/L2 control information.

17. The method of claim 11 , further comprising:

receiving, from the network node, second L1/L2 control information indicating a deallocation of the allocation of resources.

18. The method of claim 11 , further comprising:

transmitting, to the network node, an acknowledgement message in response to the received L1/L2 control information.

19. The method of claim 11 , further comprising:

determining parameters for the uplink data transmission based on a locally stored table.

20. The method of claim 11 , wherein the L1/L2 control information is received in an orthogonal frequency division multiple access (OFDMA) format.
