PROTECTING A TIME INTERVAL FOR TRANSMITTING A RANGING WAVEFORM FROM TRANSMISSIONS BY LEGACY COMMUNICATION DEVICES |
摘要 |
<p>A technique is provided to enable a ranging-enhanced communication device that operates according to a legacy communication protocol to transmit a ranging waveform that is not defined in, or part of, the rules of the legacy communication protocol. In one embodiment, a ranging-enhanced communication device that is to transmit the ranging waveform generates information representing a time interval within which to wirelessly transmit a ranging waveform that is not defined by a legacy communication protocol. This information is encoded into a field of a frame that is formatted according to the legacy communication protocol to protect the time interval from transmissions by legacy communication devices that operate according to the legacy communication protocol. The ranging-enhanced communication device transmits the frame and transmits the ranging waveform during the time interval following the frame.</p> |
