Abstract

Some demonstrative embodiments include apparatuses, systems and/or methods of rescheduling beacon transmissions. For example, an apparatus may include a wireless communication unit to reschedule broadcasting of a plurality of beacons from a first beacon schedule to a second beacon schedule, comprising means for first beacon schedule including a first sequence of beacon transmission times separated by a predefined beacon interval period, and comprising means for second beacon schedule including a second sequence of beacon transmission times separated by the predefined beacon interval period, the second sequence of beacon transmission times being shifted from the first beacon transmission times by a delay period, and wherein the wireless communication unit is to transmit at least one information element including timing information of the second beacon schedule.

Claims

1-25. -25. (canceled)

26. An apparatus comprising:

a wireless communication unit to reschedule broadcasting of a plurality of beacons from a first beacon schedule to a second beacon schedule, the first beacon schedule including a first sequence of beacon transmission times separated by a predefined beacon interval period, and the second beacon schedule including a second sequence of beacon transmission times separated by said predefined beacon interval period, said second sequence of beacon transmission times being shifted from said first beacon transmission times by a delay period, and wherein said wireless communication unit is to transmit at least one information element including timing information of said second beacon schedule.

27. The apparatus of claim 26, wherein said wireless communication unit is to transmit said information element prior to broadcasting one or more beacons according to said second beacon schedule.

28. The apparatus of claim 26, wherein said wireless communication unit is to reschedule the broadcasting of said beacons according to said second beacon schedule when said wireless communication unit is to back off transmission of one or more beacons at one or more beacon transmission times of the first sequence of beacon transmission times.

29. The apparatus of claim 26, wherein said wireless communication unit is to reschedule the broadcasting of said beacons according to said second beacon schedule when an actual transmission of a predefined number of beacons according to said first beacon schedule is delayed by at least a predefined period of time.

30. The apparatus of claim 26, wherein said wireless communication unit is to broadcast said plurality of beacons over a wireless communication medium, and wherein said wireless communication unit is to reschedule the broadcasting of said beacons according to said second beacon schedule when the wireless communication medium is occupied during at least a predefined time period beginning at a beacon transmission time of the first sequence of beacon transmission times.

31. The apparatus of claim 26, wherein said wireless communication unit is to reschedule the broadcasting of said beacons according to said second beacon schedule when the first sequence of beacon transmission times at least partially overlaps one or more beacons received by said wireless communication device.

32. The apparatus of claim 26, wherein said wireless communication unit is to broadcast said information element as part of at least one beacon.

33. The apparatus of claim 26, wherein said wireless communication unit is to transmit said information element as part of a dedicated management frame.

34. The apparatus of claim 26, wherein said wireless communication unit is to transmit said information element as part of a probe response.

35. The apparatus of claim 26, wherein said wireless communication unit is to transmit said information element over a backhaul channel connecting said wireless communication unit to one or more network controllers.

36. The apparatus of claim 26, wherein said information element includes a value of said delay period.

37. The apparatus of claim 26, wherein said information element includes a time at which said second beacon schedule is to begin.

38. The apparatus of claim 26, wherein said wireless communication unit is to determine said delay period based on a shift between said first sequence of beacon transmission times and a sequence of beacons received by said wireless communication unit.

39. The apparatus of claim 26, wherein said wireless communication unit is to randomly select said delay period.

40. The apparatus of claim 26, wherein said delay period is shorter than said beacon interval period.

41. A system comprising:

an access point (AP) including;

one or more antennas; and

a wireless communication unit to reschedule broadcasting of a plurality of beacons from a first beacon schedule to a second beacon schedule, the first beacon schedule including a first sequence of beacon transmission times separated by a predefined beacon interval period, and the second beacon schedule including a second sequence of beacon transmission times separated by said predefined beacon interval period, said second sequence of beacon transmission times being shifted from said first beacon transmission times by a delay period, and wherein said wireless communication unit is to transmit at least one information element including timing information of said second beacon schedule.

42. The system of claim 41, wherein said wireless communication unit is to transmit said information element prior to broadcasting one or more beacons according to said second beacon schedule.

43. An apparatus comprising:

a wireless communication unit to receive one or more beacons according to a first beacon schedule including a first sequence of beacon transmission times separated by a predefined beacon interval period, said wireless communication unit to receive at least one information element including timing information of a second beacon schedule including a second sequence of beacon transmission times separated by said predefined beacon interval period, said second sequence of beacon transmission times being shifted from said first beacon transmission times by a delay period, wherein said wireless communication unit is to receive one or more subsequent beacons according to said second beacon schedule.

44. The apparatus of claim 43, wherein said wireless communication unit is to receive said information element as part of at least one beacon.

45. The apparatus of claim 43, wherein said information element includes a value of said delay period.

46. A product including a non-transitory storage medium having stored thereon instructions that, when executed by a machine, result in:

broadcasting one or more first beacons according to a first schedule including a first sequence of beacon transmission times separated by a predefined beacon interval period;

determining a second schedule including a second sequence of beacon transmission times separated by said predefined beacon interval period, said second sequence of beacon transmission times being shifted from said first beacon transmission times by a delay period; and

transmitting at least one information element including timing information of said second sequence.

47. The product of claim 46, wherein the instructions result in transmitting said information element prior to broadcasting one or more beacons according to said second beacon schedule.

48. The product of claim 46, wherein the instructions result in rescheduling the broadcasting of said beacons according to said second beacon schedule when transmission of one or more beacons is to be backed off from one or more beacon transmission times of the first sequence of beacon transmission times.

49. The product of claim 46, wherein the instructions result in broadcasting said information element as part of at least one beacon.

50. The product of claim 46, wherein said information element includes a value of said delay period.
