    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multistatic radar communications. In some implementations, a transmitting device may transmit, to a receiving device, a radar alert frame followed by a codeword and one or more radar pulses. The radar pulses are transmitted, using beamforming, in a number of directions. The timing information indicates a timing offset or delay between one or more codewords of the codeword sequence and the beginning of the radar pulses. The receiving device may detect one or more codewords of the codeword sequence and an echo of at least one of the radar pulses, and determine the time at which the corresponding pulse was transmitted by the transmitting device. The receiving device may compare the timing of the echo with the timing of the transmitted pulse to determine a relative distance of an object that produced the echo.

    Abstract: A technique is disclosed for reducing interference in a communication system including a plurality of wireless devices. A first device transmits an RTS-TRN frame including a Request to Send (RTS) portion and a first beam training sequence to determine whether a communication medium is available to communicate with a second device. If the communication medium is available, the second device transmits a CTS-TRN frame including a Clear to Send (CTS) portion and a second beam training sequence. One or more neighboring devices that receive the RTS-TRN frame and/or the CTS-TRN frame configure their respective antennas to generate one or more nulls aimed at the first and second devices when transmitting signals, as long as the first and second devices are communicating based on a duration field in the RTS-TRN frame and/or CTS-TRN frame. This reduces interference at the first and/or second devices.
