Abstract: Techniques are provided for radio frequency (RF) sensing using a single wireless device. An example method for determining a distance to an object with radio frequency sensing includes transmitting a radio frequency signal with a transmit channel on a wireless device, receiving a leakage signal with a receive channel on the wireless device at a first time, such that the leakage signal is based on the radio frequency signal, receiving a reflected signal with the receive channel on the wireless device at a second time, such that the reflected signal is based on the radio frequency signal reflecting from the object, and determining the distance to the object based at least in part on a difference between the first time and the second time.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reporting channel state information (CSI). In some implementations, a receiving device may acquire a set of channel frequency response (CFR) values associated with one or more sounding packets that are received from a transmitting device and may group the set of CFR values into multiple subsets according to a number of transmit antennas of the transmitting device, a number of receive antennas of the receiving device, or a number of tones spanning a bandwidth of the wireless channel. In such implementations, the receiving device may transmit one or more CSI report frames each carrying a respective subset of the CFR values. In some other implementations, a receiving device may acquire multiple CSI associated with respective sounding packets and may transmit a single CSI report frame carrying the CSI for each of the wireless channels.

Abstract: In an aspect, a wireless device is configured to transmit a physical layer protocol data unit on one or more channels, wherein the physical layer protocol data unit includes a first portion and a second portion. The first portion includes a signal length field indicating a duration of a transmission of the physical layer protocol data unit. The second portion includes a plurality of Wi-Fi sensing fields. The wireless device is configured to receive a reflected signal and a leakage signal associated with the physical layer protocol data unit. The reflected signal includes the physical layer protocol data unit reflected off of a target object. The leakage signal is associated with the physical layer protocol data unit.
