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 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.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for enhancing a beamforming training procedure. For example, according to certain aspects, devices may exchange information regarding the number of beamforming transmit sectors each device plans to use for both partial and full sector sweeps, as well as the number of receive antennas. The devices may also exchange timing information used to synchronize when the devices start to perform the partial and full sector sweeps, after detecting a lost link.
