WI-FI MESH BACKHAUL LINK TX BIASING FOR BETTER END-TO-END THROUGHPUT AND DELAY
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.
Full-Duplex, Bi-Directional, Analog Relay
A full-duplex analog relay may comprise an analog uplink relay and an analog downlink relay, and may relay signals between a transmitter and a backscatter node. The spectrum of the downlink signal transmitted by the downlink relay may be different than the spectrum of the uplink signal received by the uplink relay. Filtering may attenuate leakage from the downlink relay to the uplink relay, and vice versa. The uplink relay may create a phase offset that is opposite in sign and substantially equal in magnitude to the phase offset created by the downlink relay. The downlink and uplink relays, taken together, may created a substantially constant net phase offset. The full-duplex relay may be housed in a vehicle that moves, and may be used to determine spatial coordinates of backscatter sources that are located in the relay's environment.
Method, Apparatus and Computer Program
There is provided an apparatus including receiving, at a second node, a signal including contributions of at least one backscatter signal and at least one further signal, the at least one backscatter signal being transmitted by a respective at least one passive device in response to a first node transmitting a first signal to the at least one passive device; isolating the contribution of the at least one backscatter signal from the at least one further signal; and based on the contribution of the at least one backscatter signal, determining, by the second node, one or more parameters associated with the respective at least one passive device.
