Abstract

Systems and methodologies are described that facilitate communication by supplying an immediate re-send of an assignment, when such assignment is not decoded by an access node (“AN”). In one embodiment, the assignment to AT can be re-sent immediately, hence mitigating a requirement for the AT to indicate that “Yes” the assignment was received, or “No” that the assignment was not received. Accordingly, if the AN does not decode the assignment, the assignment is re-sent, and a request latency can be removed.

Claims

1. A method of facilitating link assignment in a wireless communication network, comprising:

supplying an assignment via an access node (AN) in response to a request; and

re-sending the assignment without being asked a new request.

2. The method of claim 1 further comprising sending the assignment for a reverse link.

3. The method of claim 1 further comprising immediately resending the assignment upon failing to decode on the assignment by the AN.

4. The method of claim 1 further comprising validating a request for an assignment when a packet is not received.

5. The method of claim 1 further comprising decoding of a package on a reverse link, to indicate validation for a correct receipt of the assignment.

6. The method of claim 1 further comprising maintaining a MAC logic for a reverse link when acknowledgment messages (ACKs) are not sent on a forward link in support of a reverse link traffic.

7. The method of claim 1 further comprising setting a predetermined limit on number of time the assignment is being re-sent.

8. The method of claim 1 further comprising sending a de-assignment message to discontinue resending the assignment.

9. The method of claim 1 further comprising eliminating a requirement for assignment acknowledgement messages on sticky assignments.

10. The method of claim 1 further comprising re-synchronizing the AN with a mobile device by the re-sending act.

11. An apparatus for facilitating link assignment comprising:

means for granting a channel assignment;

means for sending the channel assignment; and

means for immediately re-sending the channel assignment.

12. The apparatus of claim 11 further comprising means for receiving a request.

13. The apparatus of claim 11, the means for immediately re-sending the channel assignment further comprises means for re-sending the channel assignment without receiving a new request.

14. The apparatus of claim 11 further comprising means for supplying the assignment for a reverse link.

15. The apparatus of claim 11 further comprising means for selecting another resource upon re-sending the channel assignments for a predetermined number of times.

16. The apparatus of claim 12 further comprising means for determining whether AN decodes on the assignment.

17. The apparatus of claim 15 further comprising means for setting the predetermined number of times the assignment is being re-sent.

18. The apparatus of claim 11 further comprising means for assigning sticky assignments.

19. The apparatus of claim 11 further comprising means for inferring de-assignment of users.

20. The apparatus of claim 11 further comprising means for discontinuing re-sending assignments.

21. A communication system that facilitates link assignment comprising:

a scheduler component that schedules users on a reverse link, based on an assignment supplied by an AN, and;

an assignment component that supplies an immediate re-send of assignment absent a new request received by the AN.

22. The communication system of claim 21 further comprising a sticky component that assigns sticky assignments.

23. The communication system of claim 21 further comprising a decremental component that identifies a user to be decremented.

24. The communication system of claim 21 further comprising an artificial intelligence component that facilitates link assignment.

25. A processor configured to execute the following instructions:

receiving a link assignment request by AN;

sending an assignment by the AN;

the assignment not being decoded thereon; and

sending once more the assignment by the AN without a request being received thereby.

26. The processor of claim 25 further configured to execute maintaining a MAC logic for a reverse link when acknowledgment messages (ACKs) are absent on a forward link in support of a reverse link traffic.

27. The processor of claim 25 further configured to execute sending a de-assignment message to halt forwarding of the assignment.

28. The processor of claim 25 further configured to execute decrementing the assignments.

29. The processor of claim 25 further configured to execute implementing sticky assignments in conjunction with sending the assignment once more.

30. A machine-readable medium having stored thereon machine-executable instructions for:

supplying an assignment via an access node (AN) in response to a request; and

re-sending the assignment without being asked a new request.

31. The machine-readable medium of claim 30 further comprising machine-executable instructions for sending the assignment for a reverse link.

32. The machine-readable medium of claim 30 further comprising machine-executable instructions for immediately resending the assignment upon failing to decode on the assignment by the AN.

33. The machine-readable medium of claim 30 further comprising machine-executable instructions for validating a request for an assignment when a packet is not received.

34. The machine-readable medium of claim 30 further comprising machine-executable instructions for decoding of a package on a reverse link, to indicate validation for a correct receipt of the assignment.

35. The machine-readable medium of claim 30 further comprising machine-executable instructions for maintaining a MAC logic for a reverse link when acknowledgment messages (ACKs) are not sent on a forward link in support of a reverse link traffic.

36. The machine-readable medium of claim 30 further comprising machine-executable instructions for setting a predetermined limit on number of time the assignment is being re-sent.

37. The machine-readable medium of claim 30 further comprising machine-executable instructions for sending a de-assignment message to discontinue resending the assignment.

38. The machine-readable medium of claim 30 further comprising machine-executable instructions for eliminating a requirement for assignment acknowledgement messages on sticky assignments.

39. The machine-readable medium of claim 30 further comprising machine-executable instructions for re-synchronizing the AN with a mobile device by the re-sending act.

40. A wireless communications apparatus, comprising:

a memory that retains data related to channel assignments associated with reverse link communication; and

a processor that enables supplying an assignment via an access node in response to a request, and re-sending the assignment without being asked a new request.

41. The wireless communications apparatus of claim 40, the processor further re-sends the assignment for a pre-determined number of times.

42. The wireless communication apparatus of claim 40, the processor further assigns sticky assignments.

43. The wireless communication apparatus of claim 40, the processor further halts re-sending the assignments.

44. The wireless communication apparatus of claim 40, the processor further re-synchronizes an AN with a mobile device by resending the assignment.
