An apparatus of an access point (AP) is disclosed, where the apparatus comprises processing circuitry configured to encode for transmission to a station (STA) a frame comprising a configuration hold subfield, the hold subfield indicating whether the STA should maintain a transmit configuration unchanged during uplink (UL) sensing. The processing circuitry further configured to encode for transmission a trigger frame (TF) for sensing, the TF for sensing including an identification of the STA, an indication of a resource unit (RU) for the STA to use to transmit an uplink (UL) sensing packet, and TF type subfield, the a TF type subfield indicating the TF for sensing.

Abstract: This disclosure describes systems, methods, and devices related to WLAN sensing sounding. A device may identify a sensing null data packet (NDP) request frame received from a second device, the sensing NDP request frame associated with performing a wireless local area network channel sounding procedure; identify transmit parameters included in a transmit control field of the sensing NDP request frame; generate an NDP frame using the transmit parameters; and send, in response to the sensing NDP request frame, the NDP frame to the second device.

Abstract: Embodiments of a STA configured for proximity detection by multiple WLAN link tracking are disclosed herein. In some embodiments, the STA performs WLAN sensing using two or more WLAN links with one or more other STAs to track a channel state of each link and performs motion detection based on the tracked channel state of each WLAN link to detect motion in any of the WLAN links. If motion is detected in at least some of the WLAN links, the STA may perform proximity detection to indicate proximity by combining results of the WLAN sensing for each link to determine whether the motion is proximate to the STA or proximate to one of the other STAs.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of communicating a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission. For example, a first wireless communication station may be configured to transmit a Request to Send (RTS) to a second wireless communication station via a plurality of SU MIMO Transmit (Tx) sectors of the first wireless communication station, the RTS to establish a Transmit Opportunity (TXOP) to transmit an SU-MIMO transmission to the second wireless communication station, a control trailer of the RTS including an indication of an intent to transmit the SU-MIMO transmission to the second wireless communication station; and to transmit the SU-MIMO transmission to the second wireless communication station, upon receipt of a Clear to Send (CTS) from the second wireless communication station indicating that the second wireless communication station is ready to receive the SU-MIMO transmission.
