TECHNIQUES FOR LISTEN BEFORE TALKING (LBT) ACCESS MECHANISMS FOR RADAR SYSTEMS

Abstract:

Methods, systems, and devices for wireless communications are described. A wireless device may implement one or more listen before talk (LBT) techniques. The wireless device may identify a set of transmission parameters of a signal for transmission from the wireless device. The wireless device may generate a first transmission waveform of the signal on a set of radio resources based on the set of transmission parameters. The wireless device may perform a LBT based at least in part on the generation of the first transmission waveform. In some cases, performing the LBT includes adjusting a detected signal associated with the set of radio resources based at least in part on the first transmission waveform. The wireless device may transmit the signal based on a result of the LBT.
