Sounding for radio-frequency (RF) sensing

A wireless communication device comprising:

• at least one modem;
• at least one processor communicatively coupled with the at least one modem;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor in conjunction with the at least one modem, is configured to:
• receive, over a wireless channel, sounding control information indicating a configuration of a transmitting device, wherein the sounding control information includes an indication of a number that indicates one or more transmission parameters for one or more sounding packets and timing information associated with the one or more sounding packets;
• receive a sounding packet, over the wireless channel, from the transmitting device, the sounding packet including information carried in one or more training fields configured for channel estimation;
• acquire channel state information (CSI) for the wireless channel based on the received sounding packet;
• and
• selectively transmit a channel report to the transmitting device based at least in part on the CSI and the sounding control information, wherein the channel report includes an indication of the number that indicates the one or more transmission parameters for the one or more sounding packets and the timing information associated with the one or more sounding packets.

A method for wireless communication performed by a wireless communication device, comprising:

• transmitting, over a wireless channel, sounding control information indicating a configuration of the wireless communication device, wherein the sounding control information includes an indication of a number that indicates one or more transmission parameters for one or more sounding packets and timing information associated with the one or more sounding packets;
• transmitting a sounding packet, over the wireless channel, to a receiving device, the sounding packet including information carried in one or more training fields configured for channel estimation;
• and
• receiving a channel report from the receiving device responsive to the transmission of the sounding packet, the channel report including channel state information (CSI) for the wireless channel, and the channel report including the indication of the number that indicates the one or more transmission parameters for the one or more sounding packets and the timing information associated with the one or more sounding packets.
