SOUNDING OPERATIONS FOR RADIO-FREQUENCY (RF) SENSING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18452430 titled 'SOUNDING OPERATIONS FOR RADIO-FREQUENCY (RF) SENSING

Simplified Explanation

This patent application describes methods, devices, and systems for radio frequency (RF) sensing in wireless communication systems. The innovation involves a transmitter device that sends sounding sequences for channel estimation and non-sounding frames for a channel report to a receiver device over a wireless channel. The transmitter device also sends a frame to solicit the channel report from the receiver device. The receiver device generates the channel report, which includes channel state information (CSI) of the wireless channel based on the sounding sequences. Transmitting or receiving the non-sounding frames during this time period helps prevent other devices from accessing the wireless channel when the receiver device needs more time to generate a specific type of channel report.

• The patent application focuses on RF sensing in wireless communication systems.
• A transmitter device sends sounding sequences for channel estimation and non-sounding frames for a channel report to a receiver device.
• The transmitter device solicits the channel report from the receiver device.
• The receiver device generates the channel report, including channel state information (CSI) based on the sounding sequences.
• Transmitting or receiving non-sounding frames during this time period helps prevent other devices from accessing the wireless channel when the receiver device needs more time to generate a specific type of channel report.

Original Abstract Submitted

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.
