    摘要: A method includes: A first node sends a threshold and a first packet to a second node. Correspondingly, the second node receives the threshold and the first packet from the first node. Then, the second node determines first channel state information CSI based on the first packet. If a change amount of the first CSI relative to preset CSI exceeds the threshold, the second node sends a second packet to the first node. If the change amount of the first CSI relative to the preset CSI does not exceed the threshold, the second node does not need to send the second packet to the first node. The method is applied to a radio sensing process.
