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 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 systems, methods, and apparatuses for wireless communication. In some aspects, An example method includes receiving, from a second wireless communication device, a frame associated with one or more wireless sensing measurements, verifying an integrity of the received frame associated with a message integrity code (MIC) in the received frame, and obtaining one or more wireless sensing measurements associated with the received frame.
