Abstract: A wireless communication device for communicating across a wireless communication channel includes a memory storing instructions and one or more processors coupled to the memory to execute the instructions stored in the memory. The instructions are configured to determine a plurality of channel estimation measurements corresponding to a plurality of PPDUs received from an additional wireless communication device; determine a plurality of position measurements using information about the transmission of the plurality of PPDUs, wherein the position measurement is a position of the additional wireless communication device relative to the wireless communication device; select a subset of the plurality of channel estimation measurements based on the plurality of position measurements; and determine a change in a state of the wireless communication channel based on the selected subset of the plurality of channel estimation measurements.

Abstract: This disclosure describes systems, methods, and devices related to non-trigger based (non-TB) sensing. A device may initiate sensing measurements by sending a sensing null data packet announcement (NDPA) frame to an access point (AP) responder. The device may send one or more first null data packet (NDP) packets to the AP responder. The device may identify one or more second NDP packets received from the AP responder.

Abstract: The disclosure provides techniques for a configuration of frequency domain aggregated (FA) physical layer protocol data unit (PPDU) for trigger based (TB) PPDUs. An apparatus for an access point (AP) includes a radio frequency (RF) interface; and processing circuitry coupled with the RF interface. The processing circuitry is configured to: encode a trigger frame to be transmitted via the RF interface to stations (STAs) communicatively connected with the AP, wherein the trigger frame includes signaling to indicate a configuration of frequency domain aggregated (FA) physical layer protocol data unit (PPDU) for at least two STAs; and decode an FA PPDU aggregated by composite trigger based (TB) PPDUs from the at least two STAs.

Abstract: Provided herein is a method and apparatus for transmit parameter indication in support of Wireless Local Area Network (WLAN) sensing. The disclosure provides an apparatus, comprising: a Radio Frequency (RF) interface; and processor circuitry coupled with the RF interface, wherein the processor circuitry is to: decode an Information Element (IE) received from a WLAN device via the RF interface, wherein the IE is to indicate a transmit parameter for a transmission of a Physical layer Protocol Data Unit (PPDU) of the WLAN device; and perform WLAN sensing on the WLAN device based on the IE. Other embodiments may also be disclosed and claimed.
