Receiver state estimation in a duty cycled radio

摘要

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.

主权项

1. A communications device comprising:
a receiver; a transmitter; and a processor; wherein the communications device is configured to:
communicate to a second communications device a first plurality of wake-up frames,receive, from the second communications device in response to the communicated first plurality of wake-up frames, an indication of a received wake-up frame of the communicated first plurality of wake-up frames,determine, utilizing the processor, a time at which the second communications device is in a ready state based on the received indication, andsubsequently communicate to the second communications device a second plurality of wake-up frames,wherein 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.
