Abstract: Passive and active scanning for extended range wireless networking. The choice between legacy and extended range signaling can depend on one or more factors. For passive scanning, an electronic device may transmit a combination of legacy beacons and extended range beacons for network discovery by receiving electronic devices. For active scanning, an electronic device may transmit extended range probe requests in addition to legacy probe requests to discover all of the access points within its transmission range. Responses to probe requests can use extended range, legacy, single user, and/or multi user protocols.

Abstract: Embodiments are disclosed for address changing schemes for a multi-link device in a wireless communications system. Some embodiments include a privacy enhanced (PE) access point (AP) multi-link device (MLD) that includes one or more affiliated APs operating on different links. The PE AP MLD can generate a first randomized OTA MLD address based at least on the MLD address of the PE AP MLD for a first affiliated PE AP (PE AP1). The PE AP MLD can transmit a first data transmission using the first OTA MLD address where the first data transmission includes an encrypted aggregated MAC service data unit (A-MSDU) subframe that includes the MLD address. The PE AP MLD can correlate the MLD address of the PE AP MPL with multiple addresses comprising: the first OTA MLD, a unique MLD address, and a Media Access Control (MAC) service access point (SAP) MLD address.

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).

Abstract: Embodiments are disclosed for address changing schemes in a wireless communications system. Some embodiments include an access point (AP) that can establish two or more address profiles with a station (STA), establish a schedule for switching from a first address profile to a second address profile, where the first and second address profiles are of the two or more address profiles, and transmit a first data transmission using the first address profile. Some embodiments include switching from the first address profile to the second address profile based on the schedule, and transmitting a second data transmission using the second address profile. The schedule can be based on a randomized time synchronization function (TSF). The AP can establish a joint algorithm with the STA, and use the joint algorithm determine the first and the second address profiles as well as transition times for the schedule.

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: An electronic device communicates frames with an access point (AP) by receiving, from the AP, a frame header that includes information specifying a first set of tones of an OFDMA communication, the first set of tones associated with first resource block subchannels having a first bandwidth used by the AP to transmit a frame payload. The electronic device obtains a second set of tones associated with second resource block subchannels having a second bandwidth that differs from the first bandwidth, and receives the frame payload using the OFDMA communication, the second resource block subchannels, and the second set of tones. Alternatively, an electronic device dynamically switches a channel-access mode when communicating a frame with the AP depending on whether the communication includes a primary 20 MHz channel. In a technique, an MU-PPDU is communicated using a frame via a non-primary 20 MHz channel without using the primary 20 MHz channel.

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.
