Title:
SYSTEM AND METHOD FOR COLLISION DETECTION AND MITIGATION WITH WAKE-UP PACKETS
Document Type and Number:
WIPO Patent Application WO/2018/161853
Kind Code:
A1
Abstract:
A method for collision detection by a transmission device (TD) includes identifying one or more time periods of a signal generated by the TD, the one or more time periods corresponding to periods during which the TD will not transmit energy on a shared channel, and transmitting a subset of the signal, wherein while a current time is within one of the one or more time periods, transmitting the subset of the signal comprises, turning off a transmitter of the TD at a beginning of the time period, detecting energy received on the shared channel during a portion of the time period, turning on the transmitter of the TD before an end of the time period, and determining that the detected energy meets a collision threshold, and based thereon, determining that there is a transmission collision.
