Integrated access and backhaul from high altitude platforms
A method is for establishing one or more links for an integrated access and backhaul for millimeter wave network. The network includes a high-altitude platform (HAP) as a first node and a terrestrial node as a second node. The method includes obtaining location information of the HAP in the network, determining that the HAP can be used to provide an additional access link or an additional backhaul link in the network in connection with the terrestrial node, controlling one or more transceivers of the terrestrial node to point towards the HAP according to the location information, and establishing the additional access link or the additional backhaul link between the HAP and the terrestrial node.

determining, based on the physical location information, that the HAP node can be used to provide at least one of an additional access link or an additional backhaul link in the network in connection with the terrestrial node; and
in response to the determining, transmitting instructions to the terrestrial node to cause one or more transceivers of the terrestrial node to establish at least one of the additional access link or the additional backhaul link with the HAP node according to the physical location information of the HAP node;
wherein the additional access link or the additional backhaul link is configured to operate according to a given protocol architecture including a control plane layer and a user plane layer.
10. The non-transitory, computer-readable medium of claim 9 , wherein the physical location information of the HAP node includes coordinates of a location of the HAP node.
