Abstract:
(EN) The present invention relates to a method and a device for a terminal performing decoding in a wireless communication system. According to the present invention, a method and a device may be provided, the method comprising a step for receiving a first demodulation reference signal (DMRS) and a second DMRS configured according to particular patterns from a base station via DMRS symbols, wherein the first DMRS and the second DMRS are respectively transmitted on particular antenna ports and are positioned on the same time axial symbol as that of at least one other DMRS transmitted on another antenna port, and the position of the time axial symbol of the second DMRS is determined according to a slot format or the last symbol on which downlink data is transmitted, and data is decoded using at least one of the first DMRS or the second DMRS.
(FR) La présente invention concerne un procédé et un dispositif permettant à un terminal d'effectuer un décodage dans un système de communication sans fil. La présente invention a pour objet un procédé et un dispositif, le procédé comprenant une étape consistant à recevoir un premier signal de référence de démodulation (DMRS) et un second DMRS configurés selon des motifs particuliers en provenance d'une station de base par l'intermédiaire de symboles DMRS, le premier DMRS et le second DMRS étant respectivement émis sur des ports d'antenne particuliers et positionnés sur le même symbole axial temporel que celui d'au moins un autre DMRS émis sur un autre port d'antenne, et la position du symbole axial temporel du second DMRS étant déterminée selon un format de créneau ou selon le dernier symbole sur lequel des données de liaison descendante sont transmises, et des données étant décodées à l'aide au moins du premier DMRS ou du second DMRS.
(KO) 무선 통신 시스템에서 단말이 디코딩(Decoding)을 수행하는 방법 및 장치에 관한 것이다. 본 발명에 의하면, 특정 패턴에 따라 설정된 제 1 복조 참조 신호(Demodulation Reference Signal: DMRS) 및 제 2 복조 참조 신호를 DMRS 심볼을 통해 기지국으로부터 수신하되, 제 1 복조 참조 신호 및 제 2 복조 참조 신호 각각은 특정 안테나 포트 상에서 전송되며, 다른 안테나 포트 상에서 전송되는 적어도 하나의 다른 복조 참조 신호와 동일한 시간 축 심볼 상에 위치하고, 제 2 복조 참조 신호의 시간 축 심볼의 위치는 슬롯 포맷 또는 하향링크 데이터가 전송되는 마지막 심볼에 따라 결정되며, 제 1 복조 참조 신호 또는 제 2 복조 참조 신호 중 적어도 하나를 이용하여 데이터를 디코딩하는 단계를 포함하는 방법 및 장치를 제공할 수 있다.
