Abstract
(EN) The present specification provides a method by which an integrated access and backhaul (IAB) node performs a mobile terminal (MT) operation and a distributed unit (DU) operation in a wireless communication system, the method performing initial access operations with a parent node and a child node, respectively, an MT operation with the parent node, and a DU operation with the child node, wherein a first demodulation reference signal (DMRS) is applied to the MT operation, a second DMRS is applied to the DU operation, and DMRS ports belonging to different code division multiplexing (CDM) groups are applied to the first DMRS and the second DMRS, respectively.
(FR) La présente invention concerne un procédé par lequel un nœud d'accès et de liaison terrestre intégrés (IAB) met en œuvre une opération de terminal mobile (MT) et une opération d'unité distribuée (DU) dans un système de communication sans fil, le procédé effectuant des opérations d'accès initial avec un nœud parent et un nœud enfant, respectivement, une opération MT avec le nœud parent, et une opération DU avec le nœud enfant, un premier signal de référence de démodulation (DMRS) étant appliqué à l'opération MT, un second DMRS étant appliqué à l'opération DU, et des ports DMRS appartenant à différents groupes de canaux de multiplexage par répartition en code (CDM) étant appliqués au premier DMRS et au second DMRS, respectivement.
(KO) 본 명세서는 무선 통신 시스템에서 IAB(Integrated Access and Backhaul) 노드에 의해 수행되는 MT(mobile terminal) 동작 및 DU(distributed unit) 동작을 수행하는 방법에 있어서, 부모 노드 및 자녀 노드와 이니셜 액세스 동작을 각각 수행하고, 상기 부모 노드와 상기 MT 동작을 수행하고 및 상기 자녀 노드와 상기 DU 동작을 수행하되, 상기 MT 동작에는 제1 DMRS(demodulation reference signal)가 적용되고, 상기 DU 동작에는 제2 DMRS가 적용되고, 및 상기 제1 DMRS 및 상기 제2 DMRS 각각은 서로 다른 CDM(code division multiplexing) 그룹에 속하는 DMRS 포트가 각각 적용되는 방법을 제공한다.
