Multiroute integrated access and backhaul networks

A node in 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, the node comprising:

• a memory comprising instruction data representing a set of instructions;
• and
• processing circuitry configured to communicate with the memory and to execute the set of instructions, the processing circuitry being operable configured to:
• for each candidate route, determine 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 for the data, the transmission delay being predicted for a transmission of the data that satisfies the error probability constraint in view of the channel measurements;
• and
• select 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.
