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: This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

Abstract: Apparatuses, methods, and computer readable media for assignment of secondary millimeter wave channels. An apparatus of a station (STA) is disclosed that includes processing circuitry configured to decode a basic service set (BSS) operating channels field and a primary channel field from an access point (AP) or personal basic service set control point (PCP), wherein the BSS operating channels field is a bitmap that indicates which 2.16 GHz channels of a plurality of 2.16 GHz channels are permitted to be used for transmissions in the BSS, and wherein the primary channel field indicates a 2.16 GHz channel of the plurality of 2.16 GHz channels that is a primary channel of the BSS. The processing circuitry may be further configured to determine the primary channel, a secondary channel, a secondary1 channel, and a secondary2 channel based on the BSS operating channels field and the primary channel field.
