Abstract[English]
Systems and methods for Wi-Fi sensing are provided. A method for Wi-Fi sensing carried out by sensing receiver including a transmitting antenna, a receiving antenna, and a processor is described. Initially, a compound sensing trigger message is generated. The compound sensing trigger message is then transmitted to a sensing transmitter. A sensing response announcement transmitted by the sensing transmitter is received. Also, a sensing response null data PPDU (NDP); is received. A sensing measurement is generated based on the sensing response NDP.[French]
L'invention concerne des systèmes et des procédés de détection Wi-Fi. Un procédé de détection Wi-Fi est mis en œuvre par détection d'un récepteur comprenant une antenne d'émission, une antenne de réception et un processeur. Initialement, un message de déclenchement de détection de composé est généré. Le message de déclenchement de détection de composé est ensuite émis vers un émetteur de détection. Une annonce de réponse de détection émise par l'émetteur de détection est reçue. De même, une PPDU à données nulles (NDP) de réponse de détection est reçue. Une mesure de détection est générée sur la base de la NDP de réponse de détection.
