Abstract

Systems and methodologies are described that facilitate dynamically supplementing 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. Additionally, assignment validation can be performed to mitigate generation of conflicting resource assignment to multiple devices. Moreover, resource assignments can be persisted for a mobile device.

1. A method of dynamically allocating system resources in a wireless networking environment, 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 additional resources;

generating a supplemental assignment that assigns at least one additional resource to the at least one mobile device; and

transmitting the supplemental assignment to the at least one mobile device to augment a resource set assigned to the at least one mobile device.

2. The method of claim 1, generating the supplemental assignment comprises assessing a set of all resources and determining a subset of available resources.

3. The method of claim 1, further comprising selecting available resources from the subset of available resources for supplemental assignment that minimize supplemental assignment message size.

4. The method of claim 3, further comprising selecting contiguous resources when more than one additional resource is required to supplement an assignment for the at least one mobile device.

5. The method of claim 4, further comprising generating a contiguous supplemental assignment for the at least one mobile device.

6. The method of claim 3, further comprising generating a non-contiguous supplemental resource assignment when fewer than three additional resources are required to supplement an assignment of the at least one mobile device.

7. The method of claim 1, further comprising verifying receipt of the persistent non-supplemental assignment.

8. The method of claim 7, verification of receipt of the persistent non-supplemental assignment comprises transmitting a verification message from the at least one mobile device to the network.

9. The method of claim 8, further comprising providing an indication in the verification message that the persistent non-supplemental assignment was successfully received and decoded over a reverse link.

10. The method of claim 8, further comprising providing an acknowledgement in the verification message that the persistent non-supplemental assignment was successfully received and decoded over a forward link.

11. 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 resource requirements of at least one of the plurality of mobile devices and generates a supplemental assignment to allocate additional resources to satisfy the increased resource requirements of the at least one mobile device; and

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

12. The system of claim 11, the supplemental component generates supplemental resource assignments when the assignment component employs a message format that limits resource subset assignability.

13. The system of claim 12, the message format is at least one of a contiguous block assignment technique, a channel table assignment technique, and a known-user-order assignment technique.

14. The system of claim 13, the supplemental component generates supplemental assignments in a format comprising at least one of a block index list and a contiguous block of resources.

15. The system of claim 11, further comprising a verification component that receives verification messages, through the transceiver, from mobile devices indicating receipt and successful decode of non-supplemental assignments.

16. The system of claim 15, the verification component rejects resource assignments to mobile devices that do not transmit verification messages, and rejected assigned resources retain available status.

17. The system of claim 11, further comprising an artificial intelligence (AI) component that makes inferences related to optimization of supplemental assignment generation with regard to transmission costs.

18. The system of claim 17, the AI component infers a most efficient supplemental message format based at least in part on information related to resource availability at the time of supplemental assignment generation.

19. The system of claim 11, a resource is at least one of a transmission channel, a frequency, a transmission time slot, and a code slot.

20. The system of claim 11, a mobile device comprises a wireless communication device.

21. The system of claim 11, a mobile device is at least one of a cellular phone, a laptop, and a PDA.

22. An apparatus that facilitates wireless network resource management, comprising:

means for 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;

means for determining whether the at least one mobile device requires additional resources;

means for generating a supplemental resource assignment that assigns at least one additional resource to the at least one mobile device; and

means for transmitting the supplemental assignment to the at least one mobile device to augment a resource set assigned to the at least mobile device.

23. The apparatus of claim 22, the means for generating a supplemental resource assignment comprises means for assessing all resources in the wireless network and identifying a subset of available resources.

24. The apparatus of claim 23, the means for generating a supplemental resource assignment further generates the supplemental assignment in a message having a format that minimizes transmission overhead costs.

25. The apparatus of claim 24, the message describes supplemental resources in contiguous format when more than one additional resource is required by the at least one mobile device and when sufficient contiguous resources are available.

26. The apparatus of claim 24, the message describes supplemental resources in block index list format when the at least one mobile device requires fewer than three additional resources or when sufficient contiguous resources are not available to accommodate the detected resource insufficiency at the at least one mobile device.

27. The apparatus of claim 22, further comprising means for verifying that an assignment has been received and successfully decoded by the at least one mobile device.
