1. A method for routing data by an integrated access and backhaul (IAB) donor communicating with a relaying node in a wireless communication system, the method comprising:
configuring a backhaul radio link control (RLC) channel by a central unit of the IAB donor;
configuring routing information included in a header of a packet in an adaptation layer, the packet mapped to the backhaul RLC channel, and the adaptation layer enabling data routing through a first backhaul link; and
transmitting, based on the routing information, the packet including the data for a user equipment to the relaying node, the relaying node supporting a wireless access link to the user equipment and a second backhaul link to another relaying node,
wherein the packet comprises user plane (UP) data or control plane (CP) data, and the UP data and the CP data are routed through different backhaul RLC channels.
