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 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: Certain aspects of the present disclosure provide methods and apparatus for wireless communications and, more particularly, methods and apparatus for providing channel information for multiband operation. The techniques presented herein may help a device (such as an access point) efficiently advertise availability of support in different frequency bands.

For example, by providing primary channel width and center channel frequency segments, a receiving device may be able to establish an operating link on another band without lengthy scanning to discover such channels.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for co-located Basic Service Sets (BSSs). A BSS refers to an access point (AP), wireless channel configuration, and associated stations (STAs). In one aspect, a wireless local area network (WLAN) apparatus may operate multiple virtual access points (VAPs) and multiple BSSs. The BSS may be considered co-located if they are implemented in the same physical device (such as a WLAN apparatus). Furthermore, the BSSs may be considered co-hosted if they share the same band and wireless channel, but independently signal different management frames. To aid STAs in learning about the co-located or co-hosted BSSs, the present disclosure provides techniques to advertise the co-located or co-hosted BSSs. Further improvements for co-hosted BSSs include the use of control frames that can aggregate information for more than one co-hosted BSS sharing a same wireless channel.

Abstract: Disclosed embodiments facilitate wireless channel calibration, ranging, and direction finding, between networked devices. A method on a first station (STA) may comprise: broadcasting, at a first time, a first NDPA frame to a plurality of second STAs. The first NDPA frame may include a first bit indicating that one or more subsequent frames comprise ranging or angular information. After a Short Interval Frame Space (SIFS) time interval from the first time, a second frame may be broadcast. The second frame may be a Null Data Packet (NDP) frame. In response, a plurality of Compressed Beamforming (CBF) frames may be received at the first STA where each CBF frame may be received from a distinct corresponding second STA, and may include Channel Feedback Information field with information pertaining to communication channel between the first STA and the corresponding second STA. The communications may be encoded using Orthogonal Frequency Division Multiple Access.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communication in a neighbor aware network (NAN). In one aspect, a first device of a wireless network (such as a NAN), in response to detecting a low power condition, may transmit a beacon including a power indicator. Other devices of the NAN may process the beacon and determine whether to assume a role of master or non-master sync in the NAN based on the power indicator. For example, a second device of the NAN may determine, based on power information of the second device, to assume the role of master or non-master sync in the NAN. To assume the role of master (or non-master sync), the second device may transmit a second beacon that includes a modified rank value.

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: Methods, systems, and devices are described for wireless communication. An access point may use a protection mechanism to cause stations to defer from accessing the wireless medium during a quiet duration. During the quiet duration the access point may transmit data packets to stations. After the quiet duration, a contention period may be present to allow stations to monitor the medium to make sure the medium is continuously idle before attempting a transmission. The access point may determine a quiet duration based on a number of data packets pending transmission to at least one station. Furthermore, the access point may transmit data packets to a number of stations during the quiet duration. By determining the quiet duration based on a number of data packets, the access point may reduce the overall number of contention periods which may increase throughput and decrease power consumption.
