1. An apparatus of a non-access point (non-AP) station device (STA), the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a request for an AP, to which the non-AP is associated, to establish peer-to-peer (P2P) Wi-Fi sensing operations between the non-AP STA and a second non-AP STA;
send the request, using a wireless medium, to the AP;
identify a response received from the AP using the wireless medium, the response indicating that the non-AP STA is a sensing receiver for the P2P Wi-Fi sensing operations;
identify a trigger frame received from the AP, the trigger frame associated with causing the second non-AP STA to send a sensing physical layer (PHY) protocol data unit (PPDU) to the non-AP STA for the P2P Wi-Fi sensing operations;
identify the sensing PPDU received from the second non-AP STA, the sensing PPDU comprising an indication that the second non-AP STA sent the sensing PPDU; and
determine channel state information based on the sensing PPDU, the channel state information indicative of motion of people or objects.
