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 TAB 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 on which to transmit the data packet among a plurality of egress RLC channels, based on the mapping information including the BAP address of the next hop, an identifier (ID) of at least one ingress RLC channel and an ID of at least one egress RLC channel; and
transmitting the data packet on the egress RLC channel to the next hop.
