Abstract: An example of controlling a network of wireless access points (APs) to detect that a client device associated with the network is stationary in an AP-overlap area, and in response to the detection that the client device is stationary in the AP-overlap area, assigning one of the APs to be a preferred AP for the client device. The APs are to avoid connecting with any client devices that have been assigned another AP as a preferred AP. Thus, the stationary client device in the overlap area may be prevented from undesired roaming.

Abstract: Implementations of the present disclosure relate to parallel channel switching for mesh network. In the implementations, a first access point (AP) receives a first beacon including an indication of a first channel switch count (CSC) for a first link between the first AP and the second AP from a second AP. The first AP obtains a second CSC for a second link between the first AP and a station. Then, the first AP transmits a second beacon including an indication of the second CSC to the station and within a beacon interval of the second AP upon receipt of the first beacon. In this way, the idle time period for the channel switching procedure of the mesh network can be reduced and minimized, thereby improving the Wi-Fi mesh link stability and reducing the latency.

Abstract: Systems and methods are provided for dynamic power allocation across a network deployment through a power consumption credits system that can balance a power budget throughout the network deployment by allocating credits to high power consuming network devices and generating credits by low-power consumption network devices. An example of the systems and methods associate a credit pool with a network deployment and map a number of credits to the credit pool based on a power budget. Credits can be allocated from the credit pool to network devices on the network deployment and/or accumulated into the credit pool from the network devices based on power consumption requirements of the network devices relative to a baseline.

Abstract: Systems, methods, and computer readable mediums for a TWT based multi-connection mechanism include sending, by a station, a first request for a first Target Wake Time (TWT) session with a first access point, wherein the first TWT session is established, determining, by the station and based on the first TWT session, a timing for a second TWT session such that a plurality of service periods of the first TWT session do not overlap with a plurality of service periods of the second TWT session, sending, by the station, a second request for the second Target Wake Time (TWT) session with a second access point, and wherein the second. TWT session is established, and receiving, by the station, data from the first AP during a service period of the first TWT session and data from the second AP during a service period of the second TWT session.

Abstract: Implementations of the present disclosure relate to selecting a transmitting virtual access point (VAP) for a MBSSID set. A method comprises selecting a VAP from a set of VAPs as a transmitting VAP based on context information about the set of VAPs, at least one of the set of VAPs other than the transmitting VAP being determined as at least one non-transmitting VAP The method also comprises generating a beacon frame for the set of VAPs by including an identifier of the transmitting VAP in a header part of the beacon frame and including at least one identifier of the at least one non-transmitting VAP in a payload part of the beacon frame. A generated beacon frame is broadcasted. In this way, a transmitting VAP of a set of VAPs is no longer determined by default, but can be selected for different cases.

Abstract: An example method of controlling a wireless access point may include associating accumulated-channel-resource-consumption variables with, respectively, resource consumers of the wireless access point. The method may further include, for wireless communications of the wireless access point: determining a number of spatial streams effectively consumed by the respective wireless communication; determining an operational bandwidth effectively consumed by the respective wireless communication; determining a duration of the respective wireless communication; determining a channel-resource-consumption amount for the respective wireless communication based on the number of spatial streams effectively consumed by the respective wireless communication, the operational bandwidth effectively consumed by the respective wireless communication, and the duration of the respective wireless communication; and determining values for the accumulated-channel-resource-consumption variables by accumulating the channel-resource-consumption amounts per resource consumer. The method may further include determining whether to impose channel access restrictions on the resource consumers based on their respective accumulated-channel-resource-consumption variables.

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.
