  • Patent number: 10485029
    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 correspond to periods during which the TD will not transmit energy on a shared channel. The method includes transmitting a subset of the signal. While a current time is within one of the one or more time periods, the transmitting the subset of the signal includes 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. Based on the detected energy meeting the collision threshold, the method includes determining that there is a transmission collision.
