    Abstract: A wireless local area network (WLAN) station (STA) reports, with a medium access control (MAC) frame, a buffer status of an urgent traffic identifier (TID) to a second STA. In some embodiments, the second STA is also an access point (AP). The delay in reporting is reduced by providing a buffer status report for the urgent TID in a data frame being transmitted to carry data for a current TID. The buffer status report, in some embodiments, provides the value of the urgent TID. In some embodiments, the buffer status report provides an indication of the amount of data in a buffer corresponding to the urgent TID. In some embodiments, the buffer status report is based on an aggregated measure of more than one buffer with data awaiting transmission. The transmission of the MAC frame, in some embodiments, is unsolicited.

    Abstract: Examples of the disclosure are directed to methods of managing power of various modules of an electronic device to prevent the voltage of the battery from falling to an undervoltage lockout (UVLO) threshold. In some examples, software operating on the electronic device or an associated electronic device (e.g., a paired electronic device) may assign power budgets to one or more modules, thereby preventing each module from drawing its maximum current capacity and causing the battery's voltage level to fall to the UVLO threshold. In some examples, a pre-UVLO threshold (i.e., a threshold higher than the UVLO threshold) may be used to modify the states of one or more modules to save power as the voltage of the battery approaches the UVLO threshold, but before the device must be fully powered off.

    Abstract: An access point transmits a trigger frame to a set of electronic devices in a wireless local area network (WLAN). In response to one or more requests to send data, the access point transmits the trigger frame, which includes information specifying an ordered list of electronic devices in the set of electronic devices that are allowed to transmit, and that groups the electronic devices in the ordered list of electronic devices into a first subset of the electronic devices and a second subset of the electronic devices. Subsequently, the access point sequentially receives one or more frames from the ordered list of electronic devices, where a first group of the frames received from at least some of the first subset of the electronic devices use single-user transmission and a second group of frames received from at least some of the second subset of the electronic devices use multi-user transmission.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for selectively decoding a multicast subframe in a multi-user frame for a wireless communications protocol. Embodiments include transmitting a request frame including a multicast group address for a multicast group to an access point (AP). The AP can determine a multicast identifier for the multicast group based on the multicast group address in the request frame. The AP can also transmit a response frame including the determined multicast identifier to a station (STA). The STA can receive a multi-user frame containing a multicast subframe from the AP. The STA can determine whether the multicast subframe is destined for the STA based on the determined multicast identifier and a multicast identifier stored in a preamble of the multi-user frame. The STA can determine whether to decode the multicast subframe based on the determination of whether the multicast subframe is destined for the STA.

    Abstract: The embodiments set forth herein disclose techniques for enabling a user device to seamlessly establish a secure, high-bandwidth wireless connection with a vehicle accessory system to enable the user device to wirelessly stream user interface (UI) information to the vehicle accessory system. To implement this technique, a lower-bandwidth wireless technology (e.g., Bluetooth) is used as an initial means for establishing a Wi-Fi pairing between the user device and the vehicle accessory system. Wi-Fi parameters associated with a Wi-Fi network provided by the vehicle accessory system can be communicated to the user device using the lower-bandwidth wireless technology. A secure Wi-Fi connection can then be established between the user device and the vehicle accessory system using the provided Wi-Fi parameters. The embodiments also disclose a technique for enabling the user device to automatically reconnect with the vehicle accessory system in a seamless manner (e.g., when returning to a vehicle).
