Abstract

The invention discloses a method, a device, equipment and a medium for performing wireless sensing measurement among multiple pieces of equipment. The method comprises the following steps: a second device establishes a wireless sensing measurement process with a first device and a third device respectively; the second device sends a specific trigger message to the first device; after receiving the trigger message, the first device sends an NDPA message to the responder indicated in the trigger message, and then sends a sensing data packet to the responder indicated in the trigger message; after receiving the NDPA message sent by the first equipment, the responders receive a sensing data packet sent by the first equipment, and measure and obtain wireless channel information between the responders and the first equipment; the second device acquires wireless channel information measured by these responders. According to the method and the device, the plurality of devices are controlled to participate in the wireless sensing measurement, so that the information of the plurality of wireless channels taking the target device as the center can be obtained in the wireless sensing measurement, the accuracy and the precision of the wireless sensing result are improved, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular, to a method, apparatus, device, and medium for performing wireless sensing measurement among multiple devices. Background technique [0002] Wi-Fi sensing (wireless sensing) technology is a new technology, which can realize motion detection, gesture recognition and biometric measurement by using existing Wi-Fi signals based on existing Wi-Fi networks and devices. In Wi-Fi sensing, changes caused by the motion of objects, pets, and people in the environment are detected by using CSI (Channel State Information) or Radar (Radar)-based methods without requiring the detected objects to wear any equipment. [0003] Through the implementation of Wi-Fi sensing, more intelligent and richer applications can be provided in the fields of smart home, intrusion detection, medical care, and intelligent remote care. SUMMARY OF THE INVENTION [0004] In the process of wireless...
