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 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. The signaling techniques presented herein provide, in some cases, for self-contained signaling with sufficient information for a receiving device to efficiently establish operating links in one or more other 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.

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.

For example, wireless devices may obtain measurements of range based, at least in part, on an exchange fine timing measurement (FTM) messages.

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.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may communicate with a plurality of stations in a basic service set (BSS) according to a target wakeup time (TWT) slot duration. The AP may identify one or more congestion or interference factors for the BSS. In some cases, the AP may identify a congestion score based at least in part on at least one of the one or more congestion factors from one or more stations that can be part of its own BSS, and an interference score based at least in part on at least one of the one or more interference factors form one or more stations that are not part of AP's BSS. In some cases, the AP may modify the TWT slot duration based at least in part on the congestion score and the interference score.

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.
