Abstract
This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitting device may transmit a sounding dataset, over a wireless channel, to a receiving device. The sounding dataset may include information carried in one or more training fields configured for channel estimation and sounding control information based, at least in part, on a configuration of the transmitting device. The receiving device may acquire channel state information (CSI) for the wireless channel based on the received sounding dataset and selectively generate a channel report for the wireless channel based, at least in part, on the CSI and the sounding control information. The channel report may indicate changes to the wireless channel which, in turn, may be used to sense objects in the vicinity of the transmitting device or the receiving device.
