Abstract: Embodiments of a WLAN sensing frame exchange protocol are generally described herein. In some embodiments, a wireless communication device is configured to perform a WLAN sensing protocol within a basic service set (BSS) comprising one or more stations (STAs) (STA1 and STA2) including an access point station (AP STA). The WLAN sensing protocol comprises a discovery phase, a negotiation phase, a measurement phase, and a reporting phase. To perform the WLAN sensing protocol, the wireless communication device is configured to operate as either a sensing initiator or a sensing responder, and to operate as a sensing transmitter and/or a sensing receiver. Some 60 GHz embodiments relate to WLAN sensing in a PBSS or IBSS with DMG STAs.

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: For example, an EDMG STA may generate an LDPC coded bit stream for a user based on data bits for the user in an EDMG PPDU, the LDPC coded bit stream for the user including a concatenation of a plurality of LDPC codewords, a count of the plurality of LDPC codewords is based at least on a codeword length for the user and on a code rate for the user; generate encoded and padded bits for the user by concatenating the LDPC coded bit stream with a plurality of coded pad zero bits, a count of the coded pad zero bits is based at least on a count of one or more spatial streams for the user and on the count of the plurality of LDPC codewords for the user; and distribute the encoded and padded bits for the user to the one or more spatial streams for the user.

Abstract: This disclosure describes systems, methods, and devices related to transmit power control (TPC). A device may identify a link measurement request frame from a first station device. The device may determine, for each transmit chain of the first station device, a TPC action to be performed by the first device. The device may cause to send a link measurement report frame comprising a value indicative of the TPC action for each transmit chain. The device may identify an acknowledgement from the first station device.

Abstract: An access point (AP) configured for wireless local area network (WLAN) sensing is configured to encode a trigger frame (TF) for transmission. 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.
