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.

Encrypting MAC header fields for WLAN privacy enhancement

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 AP). 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.

Address randomization schemes for multi-link devices

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.

Discovery for neighbor awareness networking

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.

Address randomization schemes

This disclosure relates to methods for low latency orthogonal frequency division multiple access communication, according to some embodiments. A wireless device may determine to communicate with another wireless device on a frequency channel as a pair of wireless devices. The wireless device may coordinate with a set of wireless device pairs to share medium access on the frequency channel. The wireless device communicate with the paired wireless device on the frequency channel in a frequency division multiplexing configuration with the set of wireless device pairs.

Low latency orthogonal frequency division multiple access transmission scheme

Systems, methods, and mechanisms for a privacy enhanced basic service set (BSS), including privacy enhancements for both access points and wireless stations as well as privacy enchantments for authentication, association, and discovery operations. Further, the systems, methods, and mechanisms disclosed may continue to support legacy wireless stations and are thus, backward compatible. A station may communicate with a legacy BSS of a wireless network to transition to a PE BSS of the wireless network. The station may receive, from the PE BSS of the wireless network, an encrypted beacon, wherein the encrypted beacon is decoded based on information received from the legacy BSS and perform, with the PE BSS of the wireless network, an encrypted handshake procedure to authenticate and associate with the PE BSS of the wireless network.

Privacy enhanced BSS and discovery mechanisms

An electronic device that performs a scan is described. During operation, the electronic device may perform, using a scanning radio, the scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon associated with a second electronic device, where the beacon includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

Beacon and probe-response frame type information for out-of-band discovery

A wireless access device can be configured to determine a list of accessory groups corresponding to accessories connected to a network managed by the wireless access device. The wireless access device may also be configured to identify at least one firmware update that corresponds to at least one accessory group of the list of accessory groups and request all firmware updates that correspond to the at least one accessory group. The wireless access device can also be configured to receive one or more firmware updates that corresponds to at least one of the accessories of the at least one accessory group for which a respective firmware update is available and transmit at least one firmware update of the received one or more firmware updates to at least one corresponding accessory of the at least one accessory group.

Network access tokens for accessories

During operation, an electronic device may perform, using a scanning radio, a scan of a band of frequencies, where the scanning radio only receives frames. Then, the electronic device may receive, using the scanning radio, a beacon frame associated with a second electronic device, where the beacon frame includes information associated with operation of a third electronic device in a second band of frequencies. Next, the electronic device may perform, using a data radio, a second scan of the second band of frequencies based at least in part on the information, where the data radio transmits and/or receives second frames, and where the second scan is performed, at least in part, while the scan is performed. Note that the electronic device may not be associated with (or may not have a connection with) the second electronic device and/or the third electronic device.

One or more wireless stations operate to configure Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, i.e., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to reciprocating service between two or more wireless stations. The reciprocating service embodiments described herein provide a mechanism through which devices can participate in a same service instant.

Neighbor awareness networking datapath—reciprocation and coexistence

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).

In-vehicle wireless communication

A controller device within a home network (or any suitable network) can be configured to manage network access tokens for various accessory devices within the home network. These network access tokens can be used by the accessory devices to access the home network without needing the network owner's network password. The network access tokens can be revocable and/or for a limited time. The controller device can generate the network access tokens, and can provide them to the accessory devices (or other user devices) as well as to an access device on the home network. Once the access device is provisioned with the accessory device's network access token, the router can control whether the accessory device is to be granted access to the home network and for how long.

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.

Wireless access protocol with collaborative spectrum monitoring

One or more wireless stations may operate to configure Neighbor Awareness Networking (NAN)&#x2014;direct communication with neighboring wireless stations, e.g., without utilizing an intermediate access point. Scheduling of NAN ranging procedures may include a first wireless station sending first information, including first scheduling preferences and a first ranging role, to a second wireless station. The first wireless station receives second information, including second scheduling preferences and a second ranging role, from the second wireless station. The first wireless station may initiate the ranging procedure based on the scheduling preferences and ranging parameters. Alternatively, the second wireless station and may initiate the ranging procedure based on the scheduling preferences and ranging parameters.
