The trigger frame allocates resource units (RUs) for receiving high-efficiency (HE) trigger-based (TB) physical-layer protocol data units (PPDUs) (HE TB PPDUs) from a plurality of client devices (non-AP STAs). The trigger frame may solicit each of the client devices to transmit an HE TB PPDU in accordance with an UL OFDMA technique or an UL MU-MIMO technique. The AP may decode the HE TB PPDUs received from the client devices and may estimate channel state information (CSI) for a radio link associated with each of the client devices based on an HE-LTF of an associated one of the HE-TB PPDUs received from one of the client devices. In accordance with these embodiments, the AP may process changes in the CSI of the radio links over time for a WLAN sensing application."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"WLAN sensing using high-efficiency (HE) trigger- based (TB) PPDUs (HE TB PPDUs)","description":"An access point (AP) configured for wireless local area network (WLAN) sensing is configured to encode a trigger frame (TF) for transmission.
