Abstract: Aspects of the present disclosure allow for improving E2E mesh throughput by applying transmission (TX) biasing on the Wi-Fi mesh backhaul. Aspects of the disclosure are directed to solutions for reducing traffic load in Wi-Fi mesh networks by applying TX biasing on the Wi-Fi mesh backhaul. Certain aspects are directed to selectively transmitting or preventing transmission of data over the first backhaul link to the first MLD based at least in part on a fronthaul airtime utilization, a first backhaul airtime utilization, or a second backhaul airtime utilization. Doing so allows a root access point or a network controller to apply TX biasing between multi-link operation links towards each repeater so that traffic load on a backhaul-link would not overly occupy the front-haul link because of common channel use by selectively transmitting or preventing transmission of data on the backhaul links.

Abstract: This disclosure provides systems, methods and apparatuses for channel selection and channel selection planning in a network including a root AP (RAP) and a number of satellite APs (SAPs). The root AP may assign operating channels for one or more of the satellite APs in a manner that optimizes network performance by considering the impact that each of the satellite APs (as well as their respective client devices) may have on the network. In some implementations, the root AP may provide centralized channel selection planning for the network based a number of network parameters observed by one or more of the satellite APs. The network parameters may include, for example, channel conditions, traffic loads, traffic patterns, service needs of client devices, available channels, and other network utilization information observed by one or more of the satellite APs.
