Integrated access backhaul configuration

An Integrated Access Backhaul, IAB, node in a wireless communication network, the IAB node being arranged to communicate backhaul traffic wirelessly with a parent node and a child node, the IAB node comprising

• a transmitter and a receiver;
• and
• a controller coupled with the transmitter and the receiver and configured to:
• control the receiver to receive a first duplexing pattern configuration message from the parent node, the first duplexing pattern configuration message including a duplexing pattern,
• control the transmitter to transmit a second duplexing pattern configuration message to the child node based on the first duplexing pattern configuration message,
• control the receiver to receive a first duplexing pattern configuration acknowledgment message from the child node as a response to the second duplexing pattern configuration message,
• after receiving the first duplexing pattern configuration acknowledgment message from the child node, apply a duplexing pattern included in the first duplexing pattern configuration message received from the parent node, and
• control the transmitter to transmit a second duplexing pattern configuration acknowledgement message to the parent node.
