Position information aided Wi-Fi sensing

An extremely high-throughput (EHT) station (STA) may encode a null data packet (NDP) announcement frame for transmission to include a high-efficiency (HE) subfield and a Ranging subfield in a Sounding Dialogue Token field. To identify the NDP announcement frame as an EHT NDP announcement frame (i.e., an EHT variant), the EHT STA may set both the HE subfield and the Ranging subfield in the Sounding Dialogue Token field to a value of one. When operating as an EHT access point (AP), the EHT STA may encode a trigger frame to include a Special User Info Field. The Special User Info Field may be identified by a predetermined value as an STA association identifier (AID) value. The use of the predetermined value as the AID value in the Special User Info Field indicates that the trigger frame is an EHT variant and indicates that the trigger frame is being sent by an EHT AP.
