Abstract: Techniques are disclosed for obfuscation in a privacy beacon. An example method includes a first communication device creating a beacon field to be included in a beacon frame. The first communication device can generate a timing synchronization field to be included in the beacon frame. The first communication device can apply an offset to the timing synchronization field of the beacon frame. The first communication device can transmit the beacon frame to a second communication device, the beacon frame comprising the offset timing synchronization field and the beacon field.

Abstract: Methods, systems and apparatuses for performing an address change by an access point (AP) multi-link device (MLD) and non-AP MLD are described. A non-AP MLD may transmit to an AP MLD, using one or more respective transmission (TX) links in an active mode, one or more uplink frames that include one or more respective initial addresses corresponding to one or more respective reception (RX) links of the AP MLD. The non-AP MLD may then configure the one or more respective TX links to a lower power mode. The non-AP MLD may configure the one or more respective TX links with one or more respective new addresses prior to transitioning the one or more respective TX links back to the active mode. The non-AP MLD may transmit, to the AP MLD, one or more additional uplink frames that include the one or more respective new addresses.

Abstract: Techniques are disclosed for obfuscation in a privacy beacon. An example method includes the first device receiving, from a second communication device, a beacon frame comprising a medium access control (MAC) header and an encrypted beacon frame field, the MAC header comprising an obfuscated timing synchronization field (TSF). The first device can select a key for de-obfuscating the TSF based at least in part on information associated with the beacon frame. The first device can de-obfuscate the TSF based at least in part on the key. The first device can decrypt the encrypted beacon frame field of the beacon frame based at least in part on information associated with the de-obfuscated TSF.

Abstract: 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.

Abstract: An electronic device is described. This electronic device may associate with a second electronic device (such as an access point) in a WLAN. While associating or associated with the second electronic device, the electronic device may receive, from the second electronic device, an AID corresponding to the electronic device for use when communicating frames in the WLAN. Moreover, while associated with the second electronic device, the electronic device may obtain a second AID corresponding to the electronic device for use when communicating second frames in the WLAN, where the associating includes replacing the AID with the second AID. Note that obtaining the second AID may include: the electronic device selecting the second AID from a predefined set of AIDs, which were previously received from the second electronic device; or the electronic device receiving, from the second electronic device, the second AID.

Abstract: This disclosure relates to methods for providing unsolicited unavailability announcements to manage the co-existence of Wi-Fi and other technologies (such as Bluetooth) and to manage infrastructure and peer-to-peer connections in a wireless communication system. A wireless device may establish multiple wireless connections on a set of radio resources. The wireless device may transmit an unsolicited unavailability announcement frame, which may include information indicating a time period of future unavailability for the wireless device on the set of radio resources. Such an unsolicited unavailability announcement frame may also include information regarding the device's current availability, for example during which the device plans to initiate a transmit opportunity.
