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.
