Abstract

Modifying a scheduled beacon transmission is disclosed. It is determined whether to modify the scheduled beacon transmission. An intent to modify the scheduled beacon transmission is announced, where the intent includes information associated with when modification of the scheduled beacon transmission occurs. The scheduled beacon transmission is modified.

Claims

1. A method of modifying a scheduled beacon transmission including:

determining whether to modify the scheduled beacon transmission;

announcing an intent to modify the scheduled beacon transmission, wherein the intent includes information associated with when modification of the scheduled beacon transmission occurs; and

modifying the scheduled beacon transmission.

2. A method as recited in claim 1, wherein a plurality of members of a beacon group transmit a beacon.

3. A method as recited in claim 1, wherein a beacon is used to announce the intent.

4. A method as recited in claim 1, wherein modifying includes modifying a beacon period start time.

5. A method as recited in claim 1, wherein modifying includes modifying a beacon period duration.

6. A method as recited in claim 1 further including protecting a beacon period associated with another beacon group.

7. A method as recited in claim 1 further including protecting a beacon period associated with another beacon group, wherein protecting includes conveying a reservation obeyed by a receiver of the reservation.

8. A method as recited in claim 1, wherein determining includes counting received beacons.

9. A method as recited in claim 1, wherein determining includes recording a time at which a beacon is received.

10. A method as recited in claim 1, wherein in the event a first beacon period overlaps with a second beacon period, modifying the scheduled beacon transmission is imminent.

11. A method as recited in claim 1, wherein in the event a first beacon period does not overlap with a second beacon period, modifying the scheduled beacon transmission is at least one superframe duration away.

12. A method as recited in claim 1, wherein modifying includes concatenating a first sequence of scheduled beacon transmission times with a second sequence of scheduled beacon transmission times.

13. A method as recited in claim 1, wherein modifying the scheduled beacon transmission is transparent to an upper layer application.

14. A method as recited in claim 1, wherein receiving the intent triggers a determination at a receiver to modify the receiver'"'"'s scheduled beacon transmission.

15. A method as recited in claim 1, wherein the intent is propagated by a receiver of the intent.

16. A system for modifying a scheduled beacon transmission including:

a processor configured to

determine whether to modify the scheduled beacon transmission; and

modify the scheduled beacon transmission; and

an interface configured to announce an intent to modify the scheduled beacon transmission, wherein the intent includes information associated with when modification of the scheduled beacon transmission occurs; and

17. A system as recited in claim 16, wherein the interface is further configured to protect a beacon period associated with another beacon group.

18. A system as recited in claim 16, wherein determining includes counting received beacons.

19. A system as recited in claim 16, wherein in the event a first beacon period overlaps with a second beacon period, modifying the scheduled beacon transmission is imminent.

20. A system as recited in claim 16, wherein modifying includes concatenating a first sequence of scheduled beacon transmission times with a second sequence of scheduled beacon transmission times.

21. A system as recited in claim 16, wherein modifying the scheduled beacon transmission is transparent to an upper layer application.

22. A computer program product for modifying a scheduled beacon transmission, the computer program product being embodied in a computer readable medium and comprising computer instructions for:

determining whether to modify the scheduled beacon transmission;

announcing an intent to modify the scheduled beacon transmission, wherein the intent includes information associated with when modification of the scheduled beacon transmission occurs; and

modifying the scheduled beacon transmission.

23. A computer program product as recited in claim 22, the computer program product further comprising computer instructions for protecting a beacon period associated with another beacon group.

24. A computer program product as recited in claim 22, wherein determining includes counting received beacons.

25. A computer program product as recited in claim 22, wherein in the event a first beacon period overlaps with a second beacon period, modifying the scheduled beacon transmission is imminent.

26. A computer program product as recited in claim 22, wherein modifying includes concatenating a first sequence of scheduled beacon transmission times with a second sequence of scheduled beacon transmission times.

27. A computer program product as recited in claim 22, wherein modifying the scheduled beacon transmission is transparent to an upper layer application.
