Abstract

A method of establishing one or more links for an integrated access and backhaul for a network, where the network includes a non-terrestrial node and a terrestrial node, includes determining a plurality of links to form between a non-terrestrial node and a number of nodes in the network and causing the plurality of links to be formed. The method also includes determining a plurality of routing paths for backhaul between the non-terrestrial node to a central server, providing instructions for backhaul between the non-terrestrial node and the central server using the plurality of routing paths, and transmitting a first set of data to backhaul via a first routing path of the plurality of routing paths and a second set of data to backhaul via a second routing path of the plurality of routing paths.

Claims (29)

1. A method of establishing one or more links for an integrated access and backhaul for a network, the network including a non-terrestrial node and a terrestrial node, the method comprising:

determining, by one or more processors of the non-terrestrial node, a plurality of links to form with a number of nodes in the network, wherein the determining of the plurality of links is based at least in part on weather conditions at a location of the terrestrial node at a future time, wherein the terrestrial node comprises a terrestrial tower;

causing, by the one or more processors, the plurality of links to be formed with the number of nodes in the network;

determining, by the one or more processors, a plurality of routing paths for backhaul between the non-terrestrial node to a central server;

providing, by the one or more processors, instructions for the backhaul between the non-terrestrial node and the central server using the plurality of routing paths; and

transmitting, by the one or more processors, an amount of data over the plurality of routing paths, including a first set of data to backhaul via a first routing path of the plurality of routing paths and a second set of data to backhaul via a second routing path of the plurality of routing paths, an amount of data over the plurality of routing paths, wherein when the amount of data is greater than a capacity of a first routing path of the plurality of routing paths, a remaining amount of data that exceeds the capacity the first routing path is transmitted over a second routing path of the plurality of routing paths, wherein the amount of data is determined based on a received indication of an estimated amount of data for transmission through the network via the non-terrestrial node, wherein the plurality of links has a combined bandwidth greater than the estimated amount of data, wherein the estimated amount of data is determined based on a size of a geographic region, and a population density of the geographic region, wherein users are provided with network access within the geographic region.

2. The method of claim 1 , wherein the determining of the plurality of links includes detecting a plurality of nodes in range of the non-terrestrial node; and

wherein the number of nodes in the network is two or more of the detected plurality of nodes.

3. The method of claim 1 , wherein the determining of the plurality of links includes receiving an indication of an estimated or actual amount of data for transmission through the network via the non-terrestrial node; and

wherein the plurality of links has a combined bandwidth greater than the estimated or actual amount of data.

4. The method of claim 1 , wherein the determining of the plurality of routing paths for backhaul is based on a topology of the network given a current position of the non-terrestrial node of the network.

5. The method of claim 1 , wherein the determining of the plurality of routing paths for backhaul includes estimating a capacity of each routing path of the plurality of routing paths.

6. A system comprising:

one or more transceivers of a non-terrestrial node configured to establish one or more links with a terrestrial node for an integrated access and backhaul; and

one or more processors configured to:

determine a plurality of links to form with a number of nodes in a network, wherein the determined plurality of links is based at least in part on weather conditions at a location of the terrestrial node at a future time, wherein the terrestrial node comprises a terrestrial tower;

cause the one or more transceivers to form the plurality of links with the number of nodes in the network;

determine a plurality of routing paths for backhaul between the non-terrestrial node to a central server;

provide instructions for backhaul between the non-terrestrial node and the central server using the plurality of routing paths; and

transmit, using the one or more transceivers, an amount of data over the plurality of routing paths, including a first set of data to backhaul via a first routing path of the plurality of routing paths and a second set of data to backhaul via a second routing path of the plurality of routing paths, wherein when the amount of data is greater than a capacity of a first routing path of the plurality of routing paths, a remaining amount of data that exceeds the capacity the first routing path is transmitted over a second routing path of the plurality of routing paths, wherein the amount of data is determined based on a received indication of an estimated amount of data for transmission through the network via the non-terrestrial node, wherein the plurality of links has a combined bandwidth greater than the estimated amount of data, wherein the estimated amount of data is determined based on a size of a geographic region, and a population density of the geographic region, wherein users are provided with network access within the geographic region.

7. The system of claim 6 , wherein the determining of the plurality of links is based on a plurality of nodes in range of the non-terrestrial node; and

wherein the number of nodes in the network is two or more of the plurality of nodes.

8. The system of claim 6 , wherein the determining of the plurality of links is based on a received indication of an estimated or actual amount of data for transmission through the network via the non-terrestrial node; and

wherein the plurality of links has a combined bandwidth greater than the estimated or actual amount of data.

9. The system of claim 6 , wherein the determining of the plurality of routing paths for backhaul is based on a topology of the network given a current position of the non-terrestrial node of the network.

10. The system of claim 6 , wherein the determining of the plurality of routing paths for backhaul is based on an estimated capacity of each routing path of the plurality of routing paths.

11. The method of claim 1 , wherein when the remaining amount of data exceeds the capacity of the second routing path, a third routing path is determined.

12. The method of claim 1 , further comprising estimating the amount of data further based on past data transmitted or past bandwidth usage.

13. The method of claim 1 , wherein the estimated amount of data is further based on past data transmitted or past bandwidth usage.
