1. A method in a node of an integrated access and backhaul, IAB, network, for selecting a preferred route from a plurality of candidate routes for sending data from a first node to a second node in the IAB network, each candidate route comprising at least one intermediate node between the first node and the second node, the method comprising:
for each candidate route, determining a predicted transmission delay associated with sending the data along the respective candidate route based on channel measurements between nodes along the respective candidate route and an error probability constraint, the transmission delay being predicted for a transmission of the data that satisfies the error probability constraint in view of the channel measurements; and
selecting a preferred route from the plurality of candidate routes for sending the data based on the predicted transmission delays, the selecting of the preferred route from the plurality of candidate routes comprises selecting the route with a smallest predicted transmission delay.
