Abstract:
(EN) The present disclosure relates to a method and device for transmitting or receiving a demodulation reference signal for an NR system. A method for receiving a demodulation reference signal (DMRS) by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, information indicating a specific combination from among candidates relating to the number of a plurality of DMRS configurations within a single slot or whether to use each of the plurality of DMRS configurations, and overhead candidates commonly applied or individually applied to the plurality of DMRS configurations; receiving the DMRS on a physical resource indicated by the specific combination; and estimating a downlink channel by using the received DMRS.
(FR) La présente invention concerne un procédé et un dispositif d'émission ou de réception d'un signal de référence de démodulation pour un système NR. Un procédé de réception d'un signal de référence de démodulation (DMRS) par un terminal dans un système de communication sans fil selon un mode de réalisation de la présente invention peut comprendre les étapes suivantes, consistant : à recevoir, en provenance d'une station de base, des informations indiquant une combinaison spécifique parmi des candidats se rapportant au nombre d'une pluralité de configurations DMRS dans un seul créneau ou s'il faut utiliser chaque configuration de la pluralité de configurations DMRS, et des candidats de surdébit communément ou individuellement appliqués à la pluralité de configurations DMRS; à recevoir le DMRS sur une ressource physique indiquée par la combinaison spécifique; et à estimer un canal de liaison descendante à l'aide du DMRS reçu.
(KO) 본 개시는 NR 시스템을 위한 복조 참조신호를 송신 또는 수신하는 방법 및 장치에 대한 것이다. 본 개시의 일 실시 예에 따른 무선 통신 시스템에서 단말이 복조참조신호(DMRS)를 수신하는 방법은, 하나의 슬롯 내의 복수의 DMRS 설정에 대한 개수 또는 상기 복수의 DMRS 설정의 각각의 사용여부에 대한 후보들, 및 상기 복수의 DMRS 설정에 대해서 공통으로 적용되는 또는 개별적으로 적용되는 오버헤드의 후보들 중에서, 특정 조합을 지시하는 정보를 상기 기지국으로부터 수신하는 단계; 상기 특정 조합에 의해서 지시되는 물리 자원 상에서 상기 DMRS를 수신하는 단계; 및 수신된 DMRS를 이용하여 하향링크 채널을 추정하는 단계를 포함할 수 있다.
