1. A method of operating a first node in a wireless communication network, the method comprising:
receiving a data packet;
receiving a routing information from an integrated access backhaul (IAB) donor node;
receiving a mapping information from the IAB donor node;
determining a next hop for the data packet, based on a backhaul adaptation protocol (BAP) address of the next hop comprised in the routing information;
determining an egress radio link control (RLC) channel for the data packet, based on the mapping information including the BAP address of the next hop, an identifier (ID) of an ingress RLC channel and an ID of an egress RLC channel; and
transmitting the data packet to the next hop.
