Abstract: Disclosed are techniques for wireless communication. In an aspect, a first station (STA) may receive a first packet from a second STA at a first time-of-arrival of the first packet. The first STA may activate a strobe signal to store first sensor data at the first time-of-arrival, wherein the first sensor data corresponds to a sensor output of one or more sensors of the first STA at the first time-of-arrival, wherein the one or more sensors include an accelerometer, a gyroscope, a magnetometer, or any combination thereof.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a wireless device receives one or more radio frequency (RF) signals from a transmitter device, displays a first arrow and a second arrow on a user interface of the wireless device, a direction of the first arrow representing a first angle-of-arrival (AoA) estimate of the one or more RF signals, and a direction of the second arrow representing a mirror AoA estimate of the first AoA estimate, and displays one or more notifications on the user interface instructing a user of the wireless device to move the wireless device until the direction of the first arrow is aligned with the direction of the second arrow.

Abstract: This disclosure provides methods, devices and systems for reducing power consumption in neighbor awareness networking (NAN) devices. Some implementations more specifically relate to dynamically adjusting a NAN device link (NDL) schedule to reduce the idle duration of a NAN data interface (NDI). The NDL schedule identifies a number of NAN slots, per discovery window (DW) interval, during which an NDL is available for data communications between NAN devices. In some aspects, a NAN device may measure congestion on the wireless channel during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured congestion. In some other aspects, a NAN device may measure throughput on the NDL during each NAN slot within a DW interval and may dynamically update the NDL schedule based on the measured throughput.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device (WCD) may receive a beacon from a second WCD, the beacon including an indication of service-specific information associated with the second WCD. The WCD may join a cluster associated with the second WCD in association with the service-specific information indicating that a service is available. Numerous other aspects are described.

Abstract: This disclosure describes a power save mechanism for devices in a neighbor awareness networking (NAN) network. In some aspects, a NAN device is able to enter into a power save mode during a window agreed to between the NAN device and a NAN peer device. A NAN device transmits, to a NAN peer device, an indication that the wireless communication device is to enter a power save mode. For example, the NAN device may transmit a MAC packet with a more data (MD) bit set to 0. The NAN peer device may indicate that the NAN device is allowed to enter the power save mode by transmitting a MAC packet with the MD bit set to 0, or the NAN peer device may indicate that the wireless communication device is not to enter the power save mode by transmitting a MAC packet with the MD bit set to 1.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may scan a first channel for access points during a first non-extended-personal-area-network (non-XPAN) service period. The wireless communication device may scan the first channel in one or more additional non-XPAN service periods. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit a channel switch announcement indicating a time by which a channel switch is to occur, wherein the time for the channel switch is less than a beacon interval from the time by which the channel switch announcement is transmitted. The wireless communication device may perform the channel switch in accordance with the channel switch announcement. Numerous other aspects are described.

Abstract: Systems and techniques are provided for wireless communications. For example, a network device can receive an unprotected management frame indicative of a disconnection of the network device. The unprotected management frame includes an address indicative of an identified wireless access point (AP) associated with the disconnection. The network device can determine a transmitter signature associated with the unprotected management frame. The network device can determine a difference between the transmitter signature and a corresponding transmitter signature associated with a protected data frame received from the identified wireless AP. The network device can further determine, based on the difference being greater than a threshold, the unprotected management frame is not transmitted by the identified wireless AP.
