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: This application relates to electronic devices configured to connect to a wireless local area network and communicate using a trigger-based access mechanism. An access point is configured to manage the wireless local area network. The access point includes a processing subsystem configured to select a channel associated with a communications medium for communicating with the set of electronic devices. The processing subsystem is also configured to monitor the channel to detect interference from radio frequency sources not connected to the wireless local area network, receive channel information for at least one additional channel associated with the communications medium from the electronic devices, and configure an interface circuit of the access point to communicate with the set of electronic devices on a new channel based, at least in part, on the channel information. Each electronic device can be configured to collect the channel information and transmit the channel information to the access point for analysis.

Abstract: Techniques for coalescing alert notifications for applications and/or services to a primary user device of a set of multiple associated user devices within proximity of each other. When a user device is not in proximity to other associated user devices, the user device functions as a primary user device and provides alert notifications based on a default configuration and/or a user configurable setting. When the user device is within proximity of one or more other associated user devices, the user devices exchange relevant capability information and information for applications that are synchronized via network-based services. The user devices negotiate to determine a user device that serves as the primary user device to provide alert notifications for a set of applications and services common to a set of user devices. The other user devices are configured to reduce and/or suppress the alert notifications.

Abstract: Some aspects of this disclosure are directed to implementing a discovery procedure including one or more of single channel publish phases, multi-channel publish phases, and single channel subscribe phases. For example, a method includes determining, by a publisher device, a first time period for a single channel publish phase and determining, by the publisher device, a second time period for a multi-channel publish phase. The method further includes transmitting, by the publisher device, one or more frames during at least one of the first time period of the single channel publish phase or the second time period of the multi-channel publish phase. The method further includes receiving, by the publisher device, a service specific message from a subscriber device during the at least one of the first time period of the single channel publish phase or the second time period of the multi-channel publish phase.

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: Disclosed herein are system, method, and computer program product embodiments for synchronizing the switching of different wireless platforms to different portions of a frequency band. An embodiment, at a first wireless platform, operates by receiving a band switch request message from a second wireless platform, wherein the band switch request message comprises a band switch delay period for the second wireless platform. The embodiment calculates a band switch time based on a band switch delay period for the first wireless platform and the band switch delay period for the second wireless platform. The embodiment transmits a band switch accept message comprising the band switch time to the second wireless platform. The embodiment sets a first filter to operate on a second portion of the frequency band based on the band switch time. The embodiment then operates on the second portion of the frequency band.

Abstract: Embodiments are disclosed for encrypting media access control (MAC) Header fields for Wireless LAN (WLAN) privacy enhancement. For example, a transceiver of a station (STA) or an access point (AP) can set a real time Media Access Control (MAC) header bit in a payload of an aggregated MAC Protocol Data Unit (A-MPDU) subframe to an actual value of a power management (PM) field of a MAC header of the A-MPDU subframe. The transceiver can encrypt the payload, set the PM field to an over the air (OTA) PM value, and transmit the A-MPDU subframe over the air. The OTA PM value can include all zeros, a predetermined value, or a randomized value The transceiver can also set static MAC header bits in the payload of the A-MPDU subframe to corresponding actual values of an aggregated MAC service data unit (A-MSDU) present field of the A-MPDU subframe.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing address and parameter modifications for an access point (AP) and/or a station (STA). Some aspects of this disclosure relate to an electronic device. The electronic device includes a transceiver and a processor communicatively coupled to the transceiver. The processor is configured to communicate, using the transceiver, with a second electronic device that is associated with the electronic device using a first address and a first parameter of the electronic device. The processor is further configured to determine a second address and a second parameter for the electronic device, where the second address is different from the first address and the second parameter is different from the first parameter. The processor is further configured to communicate with the second electronic device using the second address and the second parameter.

Abstract: A method for operating a distributed wireless audio system including several loudspeaker cabinets all of which can communicate with each other as part of a computer network. The method receives temperature data that is indicative of temperature of a first loudspeaker cabinet, which has a network master responsibility of obtaining an audio signal from an audio source and wirelessly transmitting some of the audio signal to a second loudspeaker cabinet of several loudspeaker cabinets, for playback by the second loudspeaker cabinet, while playing back some of the audio signal by the first loudspeaker cabinet. The method determines whether a thermal threshold of the first loudspeaker cabinet has been reached, based on the temperature data. The method, in response to the thermal threshold being reached, gives up the network master responsibility from the first loudspeaker cabinet to the second loudspeaker cabinet, where doing so reduces temperature in the first loudspeaker cabinet.
