Abstract

Systems and methods are described that facilitate the determination and request of resources a node may wish to reserve. The resources include a plurality of carriers that are shared with other nodes. In an approach, the node determines a condition related to the plurality of carriers; creates an ordering of the plurality of resources; and transmits a resource utilization message (RUM) for one or more of the plurality of resources based on the ordering and the condition.

Claims

1. A method of wireless data communication comprising:

receiving, by a node, at least one control message comprising a predetermined partitioning scheme for a plurality of resources, the predetermined partitioning scheme partitioning the resources into sets of resources and assigning each of the sets of resources to at least one of a plurality of traffic classes;

determining, by the node, a quality of service at the node;

comparing, by the node, the quality of service to a quality of service requirement;

determining by the node, when the quality of service does not satisfy the quality of service requirement, one or more first resources on which to send a resource utilization message for a first traffic class, based on the first traffic class and the predetermined partitioning scheme;

creating, by the node, a carrier mask identifying second resources that the node desires to be blocked; and

transmitting by the node, on the one or more first resources, the resource utilization message including the carrier mask.

2. The method of claim 1, wherein the quality of service comprises at least one of a level of interference over thermal noise, a carrier-to-interference ratio, and a level of spectral efficiency for the plurality of resources.

3. The method of claim 1, wherein the quality of service requirement comprises at least one of a data rate, an amount of data to transmit, a level of latency, and a traffic class.

4. The method of claim 1, wherein the plurality of traffic classes comprises at least one of a voice traffic class, a data traffic class, and a video traffic class.

5. The method of claim 4, wherein the first traffic class is the data traffic class and the one or more first resources include at least one of the set of resources assigned to the voice traffic class.

6. The method of claim 4, wherein the first traffic class is the voice traffic class and the one or more first resources comprise exactly one resource assigned to the voice traffic class.

7. The method of claim 1, wherein the resource utilization message including the carrier mask is transmitted on the one or more first resources at a higher transmission power when the second resources identified by the carrier mask are high-priority resources.

8. An apparatus for wireless data communication comprising:

means for receiving, by a node, at least one control message comprising a predetermined partitioning scheme for a plurality of resources, the predetermined partitioning scheme partitioning the resources into sets of resources and assigning each of the sets of resources to at least one of a plurality of traffic classes;

means for determining, by the node, a quality of service at the node;

means for comparing, by the node, the quality of service to a quality of service requirement;

means for determining by the node, when the quality of service does not satisfy the quality of service requirement, one or more first resources on which to send a resource utilization message, based on the traffic class of the resource utilization message and the predetermined partitioning scheme;

means for creating, by the node, a carrier mask identifying second resources that the node desires to be blocked; and

means for transmitting by the node, on the one or more first resources, the resource utilization message including the carrier mask.

9. The apparatus of claim 8, wherein the quality of service comprises at least one of a level of interference over thermal noise, a carrier-to-interference ratio, and a level of spectral efficiency for the plurality of resources.

10. The apparatus of claim 8, wherein the quality of service requirement comprises at least one of a data rate, an amount of data to transmit, a level of latency, and a traffic class.

11. The apparatus of claim 8, wherein the plurality of traffic classes comprises at least one of a voice traffic class, a data traffic class, and a video traffic class.

12. The apparatus of claim 11, wherein the first traffic class is the data traffic class and the one or more first resources include at least one of the set of resources assigned to the voice traffic class.

13. The apparatus of claim 11, wherein the first traffic class is the voice traffic class and the one or more first resources comprise exactly one resource assigned to the voice traffic class.

14. The apparatus of claim 8, wherein the resource utilization message including the carrier mask is transmitted on the one or more first resources at a higher transmission power when the second resources identified by the carrier mask are high-priority resources.

15. A computer program product for wireless data communication comprising:

a non-transitory computer-readable medium comprising program code for wireless data communication, the program code comprising program instructions that, when executed by a processor, cause the processor to perform operations comprising;

receiving, by a node, at least one control message comprising a predetermined partitioning scheme for a plurality of resources, the predetermined partitioning scheme partitioning the resources into sets of resources and assigning each of the sets of resources to at least one of a plurality of traffic classes;

determining, by the node, a quality of service at the node;

comparing, by the node, the quality of service to a quality of service requirement;

determining by the node, when the quality of service does not satisfy the quality of service requirement, one or more first resources on which to send a resource utilization message for a first traffic class, based on the first traffic class and the predetermined partitioning scheme;

creating, by the node, a carrier mask identifying second resources that the node desires to be blocked; and

transmitting by the node, on the one or more first resources, the resource utilization message including the carrier mask.

16. The computer program product of claim 15, wherein the quality of service comprises at least one of a level of interference over thermal noise, a carrier-to-interference ratio, and a level of spectral efficiency for the plurality of resources.

17. The computer program product of claim 15, wherein the quality of service requirement comprises at least one of a data rate, an amount of data to transmit, a level of latency, and a traffic class.

18. The computer program product of claim 15, wherein the plurality of traffic classes comprises at least one of a voice traffic class, a data traffic class, and a video traffic class.

19. The computer program product of claim 18, wherein the first traffic class is the data traffic class and the one or more first resources include at least one of the set of resources assigned to the voice traffic class.

20. The computer program product of claim 18, wherein the first traffic class is the voice traffic class and the one or more first resources comprise exactly one resource assigned to the voice traffic class.

21. The computer program product of claim 15, wherein the resource utilization message including the carrier mask is transmitted on the one or more first resources at a higher transmission power when the second resources identified by the carrier mask are high-priority resources.
