Abstract

Systems and methodologies are described that facilitate dynamically supplementing or decrementing resource assignments to mobile devices in a wireless network environment without requiring transmission of replacement assignments. Supplemental assignments can be generated based on information related to mobile device need and resource availability. Moreover, resource assignments can be persisted for a mobile device.

Claims

1. A method of dynamically allocating system resources, comprising:

transmitting a persistent non-supplemental assignment to at least one mobile device connected to a wireless network to assign an initial set of resources to the at least one mobile device;

determining whether the at least one mobile device requires resource de-allocation;

generating a supplemental assignment that de-assigns the resources and is indicated as a supplemental assignment message; and

transmitting the supplemental assignment to the at least one mobile device.

2. The method of claim 1, generating comprises identifying at least one resource that is indicative of multiple resources to remain as part of the persistent non-supplemental assignment after a de-assignment.

3. The method of claim 1, generating comprises explicitly identifying at least one resource to remain as part of the persistent non-supplemental assignment after a de-assignment.

4. The method of claim 1, generating comprises explicitly identifying at least one resource to remove as part of a de-assignment.

5. The method of claim 1, generating comprises setting a flag in the supplemental assignment message to identify the message as a supplemental assignment.

6. The method of claim 5, wherein the flag consists of one bit.

7. A system that facilitates supplementing resource assignments for mobile devices, comprising:

an assignment component that generates non-supplemental resource assignments for a plurality of respective mobile devices, wherein the non-supplemental resource assignments are persisted until a subsequent non-supplemental resource assignment is received by the mobile device to which the assignment corresponds;

a supplemental component that receives information related to increased or decreased resource requirements of at least one of the plurality of mobile devices and generates a supplemental assignment to allocate additional resources or de-allocate existing resources to satisfy the resource requirements of the at least one mobile device; and

a transceiver that transmits supplemental assignment messages to the plurality of mobile devices.

8. The system of claim 7, the supplemental component identifies one resource that is indicative of multiple resources to remain as part of the non-supplemental resource assignment after a de-assignment.

9. The system of claim 7, the supplemental component explicitly identifies multiple resources to remain as part of the non-supplemental resource assignment after a de-assignment.

10. The system of claim 7, the supplemental component explicitly identifies multiple resources to remove as part of a de-assignment.

11. The system of claim 7, the supplemental component sets a flag in the supplemental assignment message to identify the message as a supplemental assignment.

12. The system of claim 11, wherein the flag consists of one bit.

13. An apparatus comprising:

means for generating a persistent initial resource assignment that assigns resources to at least one mobile device;

means for determining whether the at least one mobile device requires resource de-allocation;

means for generating a supplemental assignment that de-assigns the resources and is indicated as a supplemental assignment message; and

a transmitter that transmits the supplemental assignment to the at least one mobile device.

14. The apparatus of claim 13, the means for generating comprises means for identifying at least one resource that is indicative of multiple resources to remain as part of the persistent initial resource assignment after a de-assignment.

15. A mobile device, comprising:

a processor configured to identify whether an assignment message is at least one of a persistent non-supplemental assignment that assigns resources to at least one mobile device, or a supplemental assignment, and if it is a supplemental assignment to determine whether the supplemental assignment is intended to de-assign resources assigned by a prior persistent non-supplemental assignment; and

a memory coupled to the processor.

16. The mobile device of claim 15, the processor is configured to determine resources being de-assigned by the supplemental assignment.

17. The mobile device of claim 15, the processor is configured to determine multiple resources being de-assigned from one resource indicated in the supplemental assignment.

18. The mobile device of claim 15, the processor is configured to determine multiple resources being de-assigned from multiple resources indicated in the supplemental assignment.

19. The mobile device of claim 15, wherein the processor determines whether the assignment is a supplemental assignment based on a flag in the assignment message.

20. The mobile device of claim 19, wherein the flag consists of one bit.

21. A method of processing assignments, comprising:

determining whether a received assignment message is at least one of a persistent non-supplemental assignment that assigns resources to at least one mobile device, or a supplemental assignment;

if the assignment message is a supplemental assignment, then determining whether the supplemental assignment is intended to de-assign resources; and

if the supplemental assignment is a de-assignment, de-assigning resources based upon resources identified in the supplemental assignment.

22. The method of claim 21, de-assigning comprises de-assigning multiple resources based upon one identified resource that is indicative of multiple resources to remain as part of an assignment after the de-assignment.

23. The method of claim 21, de-assigning comprises de-assigning multiple resources based upon multiple identified resources that are indicative of multiple resources to remain as part of an assignment after the de-assignment.

24. The method of claim 21, de-assigning comprises de-assigning multiple resources that are the same as multiple identified resources that are indicative of multiple resources to remain as part of an assignment after the de-assignment.

25. The method of claim 21, determining comprises at least one of determining according to a flag in the assignment message to identify the message as a supplemental assignment, or determining based on an overlap of resources assigned in a previously obtained non-supplemental persistent assignment and the supplemental assignment.

26. The method of claim 25, wherein the flag consists of one bit.

27. An apparatus comprising:

means for determining whether a received assignment message is at least one of a persistent non-supplemental assignment that assigns resources to at least one mobile device, or a supplemental assignment;

means for, if the assignment message is a supplemental assignment, then determining whether the supplemental assignment is intended to de-assign resources; and

means for, if the supplemental assignment is a de-assignment, de-assigning resources based upon resources identified in the assignment message.

28. The apparatus of claim 27, means for de-assigning comprises means for de-assigning multiple resources based upon one identified resource that is indicative of multiple resources to remain as part of an assignment after the de-assignment.

29. The apparatus of claim 27, means for de-assigning comprises means for de-assigning multiple resources based upon multiple identified resources that are indicative of multiple resources to remain as part of an assignment after the de-assignment.

30. The apparatus of claim 27, means for de-assigning comprises means for de-assigning multiple resources that are the same as multiple identified resources that are indicative of multiple resources to remain as part of an assignment after the de-assignment.

31. The apparatus of claim 27, means for determining comprises means for determining based on at least one of a flag in the assignment message to identify the message as a supplemental assignment, or an intersection of resources indicated in a previously obtained non-supplemental persistent assignment and the supplemental assignment.

32. The apparatus of claim 31, wherein the flag consists of one bit.
