Title (EN) METHOD FOR HANDLING COLLISION BETWEEN CSI-RS AND DMRS IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
(FR) PROCÉDÉ DE GESTION DE COLLISION ENTRE UN DMRS ET UN CSI-RS DANS UN SYSTÈME DE COMMUNICATION SANS FIL, ET DISPOSITIF ASSOCIÉ

Abstract:
(EN) The present specification provides a method for handling a collision between a demodulation reference signal (DMRS) and a channel state information-reference signal (CSI-RS) in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving a DMRS from a base station; receiving a CSI-RS from the base station; and when a collision between the DMRS and the CSI-RS occurs on at least one resource element (RE), puncturing a resource associated with the DMRS, or a resource associated with the CSI-RS on the basis of time domain behavior of the CSI-RS.
(FR) La présente invention concerne un procédé de gestion de collision entre un signal de référence de démodulation (DMRS) et un signal de référence d'informations d'état de canal (CSI-RS) dans un système de communication sans fil. De façon plus spécifique, le procédé, qui est exécuté par un terminal, comprend les étapes consistant à : recevoir un DMRS, d'une station de base ; recevoir un CSI-RS, de la station de base ; et lorsqu'une collision entre le DMRS et le CSI-RS se produit sur au moins un élément de ressource (RE), poinçonner une ressource associée au DMRS, ou une ressource associée au CSI-RS, sur la base d'un comportement du CSI-RS dans le domaine temporel.
(KO) 본 명세서는 무선 통신 시스템에서 복조 참조 신호(demodulation reference signal, DMRS)와 CSI-RS(channel state information-reference signal) 간의 충돌을 핸들링하기 위한 방법을 제공한다. 구체적으로, 단말에 의해 수행되는 방법은, 상기 DMRS를 기지국으로부터 수신하는 단계; 상기 CSI-RS를 상기 기지국으로부터 수신하는 단계; 및 적어도 하나의 자원 요소(resource element, RE)에서 상기 DMRS와 상기 CSI-RS 간 충돌이 발생한 경우, 상기 CSI-RS의 시간 영역 행동(time domain behavior)에 기초하여 상기 DMRS와 관련된 자원 또는 상기 CSI-RS와 관련된 자원을 펑처링(puncturing)하는 단계를 포함하는 것을 특징으로 한다.
