1. A method performed by a first integrated access and backhaul (IAB) node that is a relay node in a wireless communication system, the method comprising:
receiving, from an IAB donor node, a first message including configuration information of a first channel, wherein the configuration information includes first information on an identity of the first channel, and second information configuring a radio link control (RLC) entity and a logical channel corresponding to the first channel;
receiving, from the IAB donor node, a second message including third information on an identity of a second channel for a second IAB node, fourth information on an identity of the second IAB node, and mapping information for the second channel, wherein the mapping information includes fifth information on the identity of the first channel, and sixth information on an identity of a node transmitting downlink data to the first IAB node; and
transmitting the downlink data to the second IAB node via the second channel, based on the first message and the second message.
