1. A method comprising:

  • sending a discovery message from a first device to a second device,wherein the discovery message includes data indicating whether a range determination mechanism is to be used to determine whether to perform an action in response to the discovery message,wherein the data includes a range adaptation bit,wherein a first value of the range adaptation bit indicates that the second device is to further process the discovery message after detecting the range adaptation bit independent of whether a distance between the first device and the second device is within a discovery range threshold, andwherein a second value of the range adaptation bit indicates that the second device is to selectively process or discard the discovery message based on whether the distance is within the discovery range threshold.
