Abstract: 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.

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: 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.

Abstract: This disclosure relates to methods for providing detailed basic service set load information in a wireless local area network. A wireless device may receive basic service set load information including one or more of overlapping basic service set channel utilization information, in basic service set channel utilization information for a basic service set, or load history information for the basic service set. The wireless device may select a basic service set with which to associate based at least in part on the load information for the basic service set.

Abstract: Techniques are directed toward secure scrambling. An example method includes a first device encrypting a payload to be included in a physical layer protocol data unit (PPDU) frame. The determining a PPDU frame type based at least in part on an association with a second device. The first device can select a key based at least in part on the association with second device. The first evice can encrypt a payload to be included in a physical layer protocol data unit (PPDU) frame. The first device can determine a PPDU frame type based at least in part on an association with a second communication device. The first device can obfuscate the field of the MAC header. The first device can scramble the encrypted payload using a service field value. The first device can transmit the PPDU frame to the second 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: 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: 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: Methods, systems and apparatuses for non-access point (non-AP) and access point (AP) multi-link devices (MLDs) are described. A non-AP MLD can transmit, to an AP MLD, a query for information comprising at least one of one or more sets of parameters or identities associated with one or more target AP MLDs. The non-AP MLD can receive, from the AP MLD, a message comprising the information and select, based at least in part on the information, a target AP MLD of the one or more target AP MLDs. The non-AP MLD can transmit a roaming request to the target AP MLD and further receive a roaming response from the target AP MLD.
