摘要：
Methods, systems, and devices for wireless communications are described. An input node of a multi-hop network may determine a first hop degree distribution based on a desired last hop degree distribution at an output node. The input node may be an integrated access and backhaul (IAB) network node, such as a user equipment (UE), a base station, an IAB relay node, or another wireless device. The input node may encode packets using a fountain code (e. g. a Luby transform (LT) code, a rapid tornado (Raptor) code, etc. ), where encoding the packets may be based on the determined first hop degree distribution. In some examples, the input node may further determine the first hop degree distribution based on parameters of the multi-hop network. The described techniques may enable IAB network nodes to improve efficiency and reliability of communications in a multi-hop network by increasing the probability of successfully decoding transmitted packets.
