Title
(EN) INITIAL ACCESS METHOD OF IAB NODE IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS USING SAME METHOD
(FR) PROCÉDÉ D'ACCÈS INITIAL D'UN NŒUD IAB DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET APPAREIL CORRESPONDANT

Abstract
(EN) An initial access method of an integrated access and backhaul (IAB) node in a wireless communication system and an apparatus using the method are provided. The method includes: receiving, from a parent node, a synchronization signal block (SSB) and system information; and performing a random access procedure with the parent node on the basis of the SSB and the system information, wherein the SSB and the system information are received through a resource allocated to an access link of the parent node, and the random access step is performed through a resource allocated to the backhaul link of the parent node, and the random access step is performed using resources determined differently depending on whether the IAB node is a relay node or a terminal.
(FR) L'invention concerne un procédé d'accès initial d'un nœud d'accès et de liaison terrestre intégré (IAB) dans un système de communication sans fil et un appareil correspondant. Le procédé consiste : à recevoir, en provenance d'un nœud parent, un bloc de signal de synchronisation (SSB) et des informations système ; et à effectuer une procédure d'accès aléatoire avec le nœud parent en fonction du SSB et des informations système, le SSB et les informations système étant reçus par l'intermédiaire d'une ressource attribuée à une liaison d'accès du nœud parent, l'étape d'accès aléatoire étant effectuée par l'intermédiaire d'une ressource attribuée à la liaison terrestre du nœud parent, et l'étape d'accès aléatoire étant effectuée à l'aide de ressources déterminées différemment selon que le nœud IAB est un nœud relais ou un terminal.
(KO) 무선 통신 시스템에서 IAB(Integrated Access and Backhaul) 노드의 초기 접속 방법 및 상기 방법을 이용하는 장치를 제공한다. 상기 방법은 부모 노드로부터 동기화 신호 블록(synchronization signal block: SSB) 및 시스템 정보를 수신하고, 상기 SSB 및 상기 시스템 정보에 기반하여 상기 부모 노드와 랜덤 액세스 과정을 수행하는 것을 포함하되, 상기 SSB 및 상기 시스템 정보는 상기 부모 노드의 액세스 링크에 할당된 자원을 통해 수신되고, 상기 랜덤 액세스 과정은 상기 부모 노드의 백홀 링크에 할당된 자원을 통해 수행되며, 상기 IAB 노드가 중계 노드인지 단말인지에 따라 다르게 결정되는 자원을 이용하여 상기 랜덤 액세스 과정이 수행되는 것을 특징으로 한다.
