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.

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.
