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 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.
