1. A method performed by a first integrated access and backhaul (IAB) node which is a F1-terminating IAB donor node in a wireless communication system, the method comprising:
receiving, from a second IAB node which is a non-F1-terminating IAB donor node, a first message including backhaul (BH) related information for a non-F1-terminating topology associated with the second IAB node, wherein the BH related information includes at least one of information on an identity of a BH radio link control (RLC) channel, or information on a next-hop backhaul adaptation protocol (BAP) address; and
transmitting, to a third IAB node which is an IAB node connected with the first IAB node and the second IAB node, a second message including configuration information for the third IAB node, wherein the configuration information includes at least one of information indicating a type of traffic as a BAP control protocol data unit (PDU), information on an egress BH channel identity, or information indicating the non-F1-terminating topology.
