Summary:According to an embodiment of the present invention, a communication method of a first integrated access backhauled (IAB) node in a wireless communication system comprises the following steps of: receiving a radio link failure (RLF) detection notification from a parent IAB node; and performing handover to a target cell, routing to a path other than a path through the parent IAB node, or resuming an operation with the parent IAB node based on the reception of the RLF detection notification. 본 개시의 일 실시예에 따르면, 무선 통신 시스템에서 제1 IAB(Integrated Access Backhauled) 노드의 통신 방법은, 부모 IAB 노드(parent IAB node)로부터 RLF(Radio Link Failure) 감지 알림(detection notification)을 수신하는 단계; 및 상기 RLF 감지 알림의 수신에 기초하여, 타겟 셀로의 핸드오버, 또는 상기 부모 IAB 노드를 통한 경로 이외의 다른 경로로의 라우팅, 또는 상기 부모 IAB 노드와의 동작 재개를 수행하는 단계를 포함할 수 있다.
