Abstract
Various embodiments herein provide techniques for integrated access and backhaul (IAB) nodes. For example, embodiments include techniques associated with: rate-proportional routing for network coding; utilizing multiple routes in IAB networks; user equipment (UE) and parent selection for efficient topology in IAB networks; establishing efficient IAB topologies; and/or adaptive coded-forwarding for network coding. Other embodiments may be described and claimed.
Claims11
One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed cause an integrated access and backhaul (IAB) node to:
- receive route information for multiple routes between a user equipment (UE) and a core network via the IAB node;
- receive configuration information to indicate a split of a data stream of the UE between the multiple routes, wherein the configuration information indicates respective fractions of the data stream that are to be sent on respective routes;
- receive data packets of the data stream;
- and
- select one of the multiple routes for respective data packets based on the configuration information such that average fractions of data transmitted via the respective routes substantially match the fractions indicated by the configuration information.
One or more non-transitory, computer-readable media (NTCRM) having instructions, stored thereon, that when executed cause an integrated access and backhaul (IAB) node to:
- receive configuration information to indicate, for a data stream associated with a routing identifier, fractions of the data stream that are to be sent over two or more respective radio links;
- receive a data packet associated with the routing identifier;
- select a first radio link of the two or more radio links based on the configuration information;
- and
- encode the data packet for transmission on the selected radio link such that average fractions of data associated with the routing identifier that are transmitted via the respective radio links substantially match the fractions indicated by the configuration information.
