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

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

In some implementations, a computing system can perform crowd sourced access point mapping using privacy preserving techniques. For example, a server device can receive access point data reports from multiple user devices that includes various attributes and/or measurements with respect to access points with which the user devices have established connections. The access point data reports can be delivered without identifying the user devices, or users thereof, and their exact locations. Based on the access point data reports, the server device can map locations of access points and relationships between access points to generate network topologies, network locations, network quality scores, and various other characteristics of networks and/or access points. The generated access point data can be served to user devices so that the user devices can improve the efficiency of the interactions between user devices and the detected access points and/or networks.

Crowd sourced privacy preserving access point mapping

This application relates to a computing device that can be configured to implement a method for enabling a nearby computing device to access a wireless network by carrying out the techniques described herein. In particular, the method can include the steps of (1) receiving a request from the nearby computing device to access the wireless network, where the request includes user information associated with the nearby computing device, (2) presenting a notification associated with the request in response to determining, based on the user information, that the nearby computing device is recognized by the computing device, and (3) in response to receiving an approval for the nearby computing device to access the wireless network: providing, to the nearby computing device, a password for accessing the wireless network.

Secure password sharing for wireless networks

Some embodiments of this disclosure include apparatuses and methods for implementing a target wake time (TWT) scheme that includes traffic differentiation and service period extension. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive an indication of traffic associated with an application. The one or more processors determine information associated with the traffic and configure the TWT scheme associated with the traffic based at least in part on the determined information. The one or more processors further communicate initial information associated with the TWT scheme to an access point of a wireless network. The initial information associated with the TWT scheme can include at least one of traffic direction information, traffic pattern information, a traffic identifier (TID), or an access category, indication (ACID).

Target wake time traffic differentiation and service period extension

Methods, systems, and apparatus are presented for performing network probing. A user equipment device (UE) may store a record associating traditional service set identifiers (SSIDs) with corresponding Short SSIDs. According to some embodiments, the UE may receive a message including a Short SSID, and determine whether a corresponding full SSID is known to the UE. Based on the determination, a probe request may be generated, addressed to either the Short SSID or the full SSID. After transmitting the probe request, the UE may receive a probe response, which may include a full SSID corresponding to the Short SSID. The UE may store a record associating the full SSID with the Short SSID, if applicable. According to some embodiments, a UE may receive a plurality of messages including respective SSIDs, and may generate a single probe request addressed to the SSIDs. The UE may receive a plurality of probe responses.

Multiple network probing

Embodiments for securely determining a separation distance between wireless communication devices is provided. These embodiments include receiving a measurement request and a first random identifier from a first wireless communication device at a second wireless communication device. The embodiments also includes deriving a transient key using the first random identifier, a second random identifier (generated by the second device), and a pre-shared key. The first and second random identifiers, the pre-shared key, and the transient key derived therefrom are shared between the first and second devices, but are not known to any other devices. The embodiments further include encrypting measurement data exchanged between the two devices using the transient key, and using the encrypted measurement data to calculate and verify a separation distance between the devices. The embodiments thus prevent dishonest wireless communication devices from intercepting communications and spoofing a location of one of the two honest devices.

Secure wireless ranging

The present disclosure describes an electronic device that includes an antenna and an interface circuit. The interface circuit communicates, via the antenna, with a companion electronic device and/or a communication hub (e.g., an access point). The companion electronic device may communicate with the communication hub over a wireless network. During operation, the electronic device receives, from the companion electronic device or an archive electronic device, network-state information including an identifier of the companion electronic device, an identifier of the communication hub, or timing-synchronization information for beacons from the communication hub. In some embodiments, the network-state information may further include a channel associated with the connection. Moreover, the electronic device may disable communication via a first communication technique (e.g., Bluetooth) and enable communication via a second communication technique (e.g., WiFi). Furthermore, the electronic device may associate with the communication hub on the wireless network based on the network-state information.

Association based on shared network-state information

After detecting an access-intent operation, an electronic device establishes a connection with a second electronic device using a communication protocol. The electronic devices exchange identifiers, and the second electronic device provides information specifying a preferred channel to use with a second communication protocol. Based at least in part on the preferred channel of the second electronic device and on communication contexts of the electronic devices, the electronic device selects a channel and transmits to the second electronic device information specifying the selected channel. The electronic device remotely accesses credential information based on the exchanged identifiers, and using the credential information, the electronic devices establish a secure connection via the selected channel using the second communication protocol. The electronic device determines a distance to the second electronic device using wireless ranging via the secure connection. When the electronic devices are proximate to each other, the electronic device can be unlocked.
