Abstract: This disclosure relates to methods for handling uplink frames in access point assisted roaming in a wireless local area network. A wireless device may establish a wireless association with a first access point. The wireless device may perform signaling to transition from the first access point to a second access point. The signaling may include an uplink reorder buffer handling request.

Abstract: In order to eliminate the reliance of ultra-high bandwidth (UWB) standalone transceivers and narrow-band-assisted (NB-assisted) UWB transceivers on BLUETOOTH™ (BLE) usage, an NB radio may be used. The NB radio may be tightly coupled with the UWB radio, for example driven by the same time source, to enable leveraged use of ACP (Acquisition Packet) for discovery, session setup, and maintenance over UWB and/or NB-assisted UWB without the use of BLE. Rules for advertising ACP and scanning for ACP may be defined for two modes of operation. An ad-hoc discovery may be based on external acquisition triggers, while a managed discovery may be based on an ongoing discovery advertisement process. ACPs may thereby be transmitted over UWB and/or NB.

Abstract: This disclosure relates to methods for multi-access point association in a wireless local area network. Multiple access point wireless devices may establish a multi-access point system. Other access point wireless devices may subsequently join the multi-access point system. Non-access point wireless devices may form an association with the multi-access point system, which may include links with multiple different access point wireless devices in the multi-access point system.

Abstract: A method for communicating over a wireless network includes broadcasting, by a Multi-Link Device (MLD) device, service data indicative of one or more services for wireless communication with a client device; wherein the service data indicates that a service type is differentiated based on a type of the client device; establishing a security association with the client device; and in response to establishing a security association with the client device, granting access by the client device to a subset of the one or more services based on the type of the client device.

Abstract: An electronic device (such as an access point) that receives one or more block acknowledgments is described. This electronic device may transmit an extremely high-throughput (EHT) physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device, where the EHT PPDU is transmitted in multiple non-contiguous sub-bands that are separated by a punctured sub-band. Moreover, the electronic may receive the one or more block acknowledgments from the recipient electronic device, where the one or more block acknowledgments exclude the punctured sub-band. Note that the EHT PPDU may exclude transmitted energy in the punctured sub-band. Moreover, the punctured sub-band may have a bandwidth of at least 20 MHz and may be different from a primary sub-band.

Abstract: A first multilink device (MLD) is configured to communicate with a second MLD using at least two communication links. The first MLD selects a first link of the at least two communication links for communications between the first MLD and the second MLD, detects that the first link is unavailable for communications, switches a radio of the first MLD to a second link of the at least two communication links, transmits an alert to the second MLD regarding the switching from the first one of the at least two communication links to the second one of the at least two communication links and communicates with the second MLD via the second link.

Abstract: An electronic device may transmit beacons associated with multiple access points that are cohosted by the electronic device, and that provide concurrent links in different bands of frequencies. The electronic device may include an access-point multi-link device (AP MLD). Moreover, the beacons may include: a basic service set identifier (BSSID) associated with the access points in the AP MLD, a service set identifier (SSID) associated with the access points in the AP MLD, and a MLD media access control (MAC) address associated with the access points in the AP MLD. Furthermore, a given beacon may be associated with a given access point and may include: information specifying a channel of a given link, a reduced neighbor report (RNR) providing information about at least the access points in the AP MLD, and a field that indicates when the given access point is included in the AP MLD.

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: Some aspects of this disclosure include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and/or sub-combinations thereof, for implementing multi-credential mapping mechanisms in wireless communication networks, such as a wireless local area network (WLAN). The multi-credential mapping mechanisms can use pointer schemes for communicating multiple credentials (e.g., Authentication and Key Managements (AKMs) and ciphers) in the wireless communication networks. The multi-credential mapping mechanisms can reduce congestion in the communication medium and improve the communications between an access point (AP) and stations (STAs).
