Abstract: Maintenance and monitoring of target wait time (TWT) sessions is described. An example includes establishing at least a first target wake time (TWT) session for a first station, the first TWT session having a first set of parameters defining a wake time, wake duration, and wake interval for service periods of the first TWT session; selecting the first TWT session for health status determination; selecting a check window for the health status determination and monitoring transmissions from the first station within the check window; based at least in part on the monitoring of the transmissions from the first station, calculating a first TWT session health status value for the first TWT session; and determining whether corrective action is required for the first TWT session based at least in part on the first TWT session health status value.

Abstract: Some examples relate to use of a three-address scheme for forwarding frames in a wireless mesh network (WMN). In an example, a node in a WMN may receive an Ethernet packet from a station outside of the WMN. The Ethernet packet may include a first address scheme comprising a destination address (DA) field, and a source address (SA) of the Ethernet packet. The Ethernet packet may be encapsulated in a second Ethernet packet comprising second address scheme. The second Ethernet packet may be encapsulated in an IEEE 802.11 frame comprising a third address scheme.

Abstract: Systems and methods are provided for upgrading wireless network devices, such as access points (APs). When a first AP needs an upgrade, a network controller of the first AP may identify and select a neighbor AP. The radio(s) of the neighbor AP can be split into multiple logical radios, at least one of which includes a backup virtual AP (VAP). The backup VAP can support client devices originally supported by the first AP, allowing those client devices to roam to the neighbor AP while the first AP is upgrading, and without needing to re-associate with the neighbor AP. From the client device perspective, it appears as though they are still being supported by the first AP. Upon upgrading the first AP, the client devices can roam back to the first AP (without needing to re-associate with the first AP). No downtime is experienced, and no RF holes are generated.

Abstract: An example network device may include a processor to receive information of a set of devices including at least one network device; estimate interferences of available basic service set (BSS) color values in a specified channel, based on the received information; and select one BSS color value with the interference lower than others from the available BSS color values.

Abstract: Systems and methods are provided for generating an MBSSID virtual access point (VAP) to facilitate an uninterrupted MBSSID. An access point (AP) can determine characteristics, or network properties, of VAPs associated with the AP. The AP can generate an MBSSID VAP based on the characteristics of the VAPs. An MBSSID beacon can be generated using the MBSSID VAP as a transmitted VAP (TX VAP) of the MBSSID beacon. The MBSSID VAP serves as a TX-VAP that is not subject to changes and does not need to be interrupted to have changes made to it. As the MBSSID VAP serves as a TX VAP that is not subject to changes or interruptions, the MBSSID based on the MBSSID VAP does not need to be interrupted for changes to be made to other VAPs associated with the MBSSID.

Abstract: Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

Abstract: Systems and methods are provided for multiple basic service set identifier (MBSSID) beaconing (from an access point (AP) standpoint) and MBSSID/virtual AP (VAP) scanning (from a client device perspective). To facilitate easier discovery of mesh APs/VAPs, BSSIDs associated with mesh VAPs can be advertised more frequently, e.g., being broadcast as a transmitted or non-transmitted BSSID in each MBSSID beacon. Additionally, information regarding mesh VAPs, such as mesh capability information, can be provided via intermediate discovery beacons or frames such that out-of-band scanning mechanisms can discover mesh VAPs faster. Additionally still, the existence of mesh VAPs can be advertised in a dedicated field of an MBSSID beacon.

Abstract: In embodiments of the present disclosure, there is provided an approach for channel sounding. According to embodiments of the present disclosure, if the CSI change rate exceeds a first threshold, the AP may disable the beamforming. If the CSI change rate does not exceed the first threshold but exceeds a second threshold below the first threshold, the AP may perform the channel sounding at a first time interval. Otherwise, if the CSI change rate does not exceed the second threshold, the AP may perform the channel sounding at a second time interval. Embodiments of the present disclosure provide an effective way for channel sounding.
