Abstract: Disclosed are methods, systems and devices for obtaining a measurement of a range between two devices. For example, wireless stations may obtain a measurement of range between the wireless stations based, at least in part, on an exchange messages such as fine timing measurement (FTM) messages. In a particular implementation, FTM messages may be received at a transceiver device in a burst of FTM messages from a responding wireless station. An acknowledgement messages may be transmitted to the responding wireless station in response to receipt of the FTM message.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for analyzing management frames for multiple basic service sets (BSSs). In one aspect, a wireless node may obtain a first management frame from a wireless local area network (WLAN) apparatus, the WLAN apparatus operating multiple virtual access points (VAPs) respectively corresponding to multiple BSSs. The wireless node may determine whether the first management frame includes a BSS profile of a BSS associated with the wireless node based, at least in part, on an arrangement of a plurality of BSS profiles within one or more management frames. The wireless node may determine to further process the first management frame based, at least in part, on a determination that the first management frame includes the BSS profile of the BSS associated with the wireless node.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling basic service set (BSS) identifiers (BSSIDs). A group of BSSs may form a Multiple BSSID set in which one BSS sent management frames on behalf of other BSSs (referred to as non-transmitting BSSIDs). For example, a management frame (such as a Beacon Frame or Probe Response Frame) may include a list of BSSIDs for some or all of the non-transmitting BSSIDs in the Multiple BSSID set. An indicator in the management frame may indicate whether the management frame includes a partial list or complete list of non-transmitting BSSIDs in the Multiple BSSID set. The management frame may include a count or bitmap to indicate the quantity of BSSIDs in the Multiple BSSID set. A station (STA) may indicate which BSSIDs it has discovered and request the remaining BSSIDs in the Multiple BSSID set.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for implementing multi-link aggregation and conditional inheritance in a first basic service set (BSS). In one aspect, an apparatus may establish a first communication link with a first station (STA) of the first BSS using a first frequency band. The apparatus may determine a first link profile for a second communication link by customizing one or more management elements of management information associated with the first communication link. The apparatus may configure a first non-inheritance element of the first link profile associated with the second communication link to indicate usage of at least one management element of the management information by the second communication link is disabled. The apparatus may generate a management frame that comprises at least the first link profile, and may output the management frame for transmission.

Abstract: Disclosed are methods, systems and devices for obtaining a range between devices based, at least in part, on an exchange of wireless messages. For example, wireless devices may obtain measurements of range based, at least in part, on an exchange fine timing measurement (FTM) messages. In one implementation, an initial FTM request message may be transmitted from a first wireless transceiver device to a second wireless transceiver device comprising one or more parameters indicative of a request for transmission of FTM messages in a particular format.

Abstract: This disclosure provides systems, methods and apparatuses for selectively acquiring communication frames from a transmitting device capable of formatting the communication frames in accordance with a plurality of PHY formats. In some implementations, a STA may filter or discard duplicate frames received from an AP based, at least in part, on a preference of the STA for one of the plurality of PHY formats. The filtering may be performed at the PHY, without forwarding received communication frames to the media access control layer (MAC) for further processing. In some other implementations, an AP may refrain from sending duplicate frames to a STA based, at least in part, on a preferred frame format of the STA. Still further, in some implementations, the STA may dynamically adjust or update its preferred frame format based on changes in the distance, or channel conditions, between the STA and the AP.

Abstract: Method, systems, and apparatuses are described for wireless communications. More particularly, a wireless station may connect to a wireless network using a first radio frequency (RF) band and detect a signal strength of the first RF band is greater than a roaming threshold. The wireless station may perform a plurality of scans for support by the wireless network of a second RF band in response to the detected signal strength. Each scan may occur when the signal strength of the first RF band is greater than the roaming threshold. The wireless station may selectively connect to the wireless network using the second RF band based at least in part on the scanning and a throughput supported by the wireless network over the second RF band. The first RF band may be a 2.4 GHz band and the second RF band may be a 5 GHz band.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless devices may use multiple transmission modes to enable association and authentication procedures for wireless devices with different capabilities. For example, a station may receive, in response to a broadcast probe request, a probe response frame formatted according to a first transmission mode. The station may then transmit a second probe request frame formatted according to the first transmission mode. At some later time, the station may identify that the second probe request frame was not received by the wireless device, and may transmit another probe request frame formatted according to an extended range transmission mode. The station may then establish a connection with the wireless device by completing an association and authentication procedure, and proceed to transmit data or control frames formatted according to the extended range transmission mode.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) transmits instructions to quiet a dynamic frequency selection (DFS) home channel for a period of time. Instructions can include a quiet information element (IE) or a clear-to-send to self (CTS2Self) frame. The AP then allocates a first dedicated RF chain to a first media access control (MAC) component and a second dedicated RF chain, separate from the first dedicated RF chain, to a second MAC component of the access point. The allocation can include reducing the number of RF chains dedicated to the first MAC component. During the time period determined by the instructions, the first dedicated RF chain scans the home DFS channel and the second dedicated RF chain scans at least one other channel (e.g., based at least in part on the time period and channel scan priority) in the same band as the DFS home channel.
