Abstract
A method for receiver state estimation includes communicating, from a first communications device to a second communications device, a first plurality of wake-up frames; receiving, at the first communications device from the second communications device, an indication of a received wake-up frame of the communicated first plurality of wake-up frames; determining, by the first communications device, a time at which the second communications device is in a ready state based on the received indication; subsequently communicating, from the first communications device to the second communications device, a second plurality of wake-up frames. The first plurality is greater than the second plurality, the reduction in number from the first plurality to the second plurality being based on the determined time at which the second communications device is in a ready state.

21. A method for reducing a number of wake-up frames in a sequence of wake-up frames, comprising:
-
receiving, from a communications device, an identification of a wake-up frame of a first sequence of wake-up frames transmitted to the communications device; and determining, based on the identification, a number of wake-up frames in a second sequence of wake-up frames, the number of wake-up frames in the second sequence being less than a number of wake-up frames in the first sequence. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A communications device, comprising:
-
a receiver configured to receive, from an additional communications device, an identification of a wake-up frame of a first sequence of wake-up frames transmitted to the additional communications device; and a processor configured to determine, based on the identification, a number of wake-up frames in a second sequence of wake-up frames, the number of wake-up frames in the second sequence being less than a number of wake-up frames in the first sequence. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38)

39. A communications device, comprising:
-
a transmitter configured to communicate a first plurality of wake-up frames to an additional communications device; a receiver configured to receive, from the additional communications device in response to the first plurality of wake-up frames, an indication of a received wake-up frame of the first plurality of wake-up frames; a processor configured to determine a time at which the additional communications device is in a ready state based on the indication; and the transmitter configured to subsequently communicate, to the additional communications device, a second plurality of wake-up frames, the first plurality of wake-up frames being greater than the second plurality of wake-up frames, a reduction in a number of the first plurality of wake-up frames to the second plurality of wake-up frames being based on a time at which the additional communications device is in the ready state. - View Dependent Claims (40, 41, 42, 43, 44)

45. A communications device, comprising:
-
a transmitter configured to communicate a first plurality of wake-up frames, to an additional communications device; a receiver configured to receive, from the additional communications device in response to the first plurality of wake-up frames, an indication of a received wake-up frame of the first plurality of wake-up frames, a processor configured to determine an offset time relative to a clock of the communications device based on the indication; and the transmitter configured to subsequently communicate, to the additional communications device, a second plurality of wake-up frames, the first plurality of wake-up frames being greater than the second plurality of wake-up frames, a reduction in a number of the first plurality of wake-up frames to the second plurality of wake-up frames being based on the determined offset time. - View Dependent Claims (46)

52. A system, comprising:
-
a first communications device configured to transmit a first plurality of wake-up frames to a second communications device; the second communications device configured to; receive one or more wake-up frames of the first plurality of wake-up frames from the first communications device; based upon the receipt of the one or more wake-up frames of the first plurality of wake-up frames, transmit an indication of a received wake-up frame to the first communications device; the first communications device configured to; receive the indication of the received wake-up frame from the second communications device; based upon the receipt of the indication, determine an offset time relative to a clock of the first communications device, and subsequently transmit a second plurality of wake-up frames to the second communications device, the first plurality of wake-up frames being greater than the second plurality of wake-up frames, a reduction in a number from the first plurality of wake-up frames to the second plurality of wake-up frames being based on the determined offset time. - View Dependent Claims (47, 48, 49, 50, 51, 53)
