    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for radio frequency (RF) sensing in the millimeter-wave frequency spectrum that can be performed over multiple phases. During a session setup phase, a radar initiator identifies one or more wireless stations (STAs) that are capable of radar ranging and sets up a radar measurement session that includes at least one of the identified STAs. During a measurement negotiation phase, the radar initiator performs a respective beamforming training operation with each STA and indicates, to each STA, one or more parameters associated with the radar measurement session. During a radar measurement phase, the radar initiator transmits radar setup information to, and receives ranging information from, each STA. In some aspects, the radar initiator may perform an object detection operation that indicates a location of an object associated with the ranging information received from each radar STA.

    Abstract: This disclosure provides systems, methods, and apparatuses for wireless sensing. In some aspects, a first wireless communication device may receive a first wireless transmission including a transmit (TX) parameter information element (IE). The first wireless communication device may verify the integrity of the TX parameter IE using a message integrity code (MIC) in the first wireless transmission, discarding the first wireless transmission when the MIC does not verify the integrity of the TX parameter IE. The first wireless device may obtain one or more transmission parameters for one or more second wireless communication devices associated with the TX parameter IE. The first wireless communication device may receive a second wireless transmission from one of the second wireless communication devices and obtain one or more wireless sensing measurements associated with the second wireless transmission and the one or more transmission parameters.

    Abstract: This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitter device transmits sounding sequences configured for channel estimation over a wireless channel to a receiver device. The transmitter device also transmits or receives non-sounding frames associated with a channel report of the receiver device. The transmitter device transmits a frame soliciting the channel report from the receiver device. The transmitter device receives the channel report, which may include channel state information (CSI) of the wireless channel responsive to at least the sounding sequences. Some types of channel reports may take longer to generate than other types of channel reports. Transmitting or receiving the non-sounding frames during the time period may prevent other devices from accessing the wireless channel when the receiver device needs additional time to generate a certain type of channel report.

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for multistatic radar communications. In one aspect, a wireless communication device may determine a distance and direction of one or more receiving devices. The wireless communication device may transmit, to the one or more receiving devices, timing information indicating a timing relationship between a codeword sequence and one or more pulses. The wireless communication device may transmit a respective codeword of the codeword sequence in the direction of each of the one or more receiving devices. The wireless communication device may further transmit the one or more pulses in a plurality of directions. The wireless communication device may receive feedback from at least one of the one or more receiving devices and determine ranging information about an object based on the feedback and the distance or direction of at least one receiving device.

    Abstract: This disclosure provides methods, apparatuses, wireless nodes and computer-readable mediums for wireless communications. In one aspect, wireless, or WiFi, sensing involves a device transmitting WiFi signals, while another device, or devices, use reflections of those signals to map and measure the environment. WiFi sensing may be used to obtain rough dimensions of a room, identify stationary objects in a room, or detect objects (such as people) moving into, out of, or within a room. Multi-static WiFi sensing can occur when two devices are simultaneously transmitting and receiving WiFi signals.
