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: Wireless stations and access points may perform a wireless local area network (WLAN) sensing operation using a basic sensing by proxy (SBP) procedure driven by an SBP responder, in which case the sensing features associated with the SBP procedure are dictated by the SBP responder, or driven by an SBP initiator, in which case the sensing features are dictated by the SBP initiator. For an SBP responder driven SBP procedure, the SBP session may be requested with a reduced number of parameters that include number of respondents and maximum bandwidth. For an SBP initiator driven SBP procedure, suitable sensing responders may be identified and instructed prior to receiving a sensing request. The WLAN sensing session may be paused to enter doze mode during which no sensing frame exchanges take place between participating nodes and the WLAN sensing session does not expire and is not terminated, and may resume upon exiting doze mode.

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: 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.

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.
