摘要:
(EN) The present invention relates to a method and a device for transmitting and receiving a reference signal by a terminal in a wireless communication system. According to the present invention, provided are a method and a device, a method in which a first dedicated demodulation reference signal and a first physical downlink shared channel (PDSCH) are received from a base station, a physical downlink control channel (PDCCH) comprising downlink control information (DCI) associated with the configuration of a second dedicated demodulation reference signal is received on the basis of the first PDSCH, and the second dedicated demodulation reference signal and a second PDSCH are received on the basis of the PDCCH, wherein the first dedicated demodulation reference signal is transmitted on only one antenna port, and the configuration of the DCI is determined in accordance with the maximum number of symbols to which the second dedicated demodulation reference signal is mapped.
(FR) La présente invention concerne un procédé et un dispositif de transmission et de réception de signal de référence par un terminal dans un système de communication sans fil. La présente invention concerne un procédé et un dispositif, un procédé dans lequel un premier signal de référence de démodulation dédié et un premier canal partagé de liaison descendante physique (PDSCH) sont reçus en provenance d'une station de base, un canal de commande de liaison descendante physique (PDCCH) comprenant des informations de commande de liaison descendante (DCI) associées à la configuration d'un second signal de référence de démodulation dédié est reçu sur la base du premier PDSCH, et le second signal de référence de démodulation dédié et un second PDSCH sont reçus sur la base du PDCCH, le premier signal de référence de démodulation dédié étant transmis sur un seul port d'antenne, et la configuration des DCI étant déterminée en fonction du nombre maximal de symboles auxquels le second signal de référence de démodulation dédié est mis en correspondance.
(KO) 무선 통신 시스템에서 단말이 참조 신호 (Reference Signal)을 송수신 하는 방법 및 장치에 관한 것이다. 본 발명에 의하면, 기지국으로부터 제 1 복 조 참조 신호 (Dedicated Demodulation Reference Signal 및 제 1 PDSCH (Physical Downlink Shared Channel)을 수신하고, 상기 제 1 PDSCH에 기초하여 제 2 복조 참조 신호의 구성과 관련된 DCI (Downlink Control Information)을 포함하는 PDCCH (Physical Downlink Control Channel)을 수신하며, 상기 PDCCH에 기초하여 제 2 복조 참조 신호 및 2 PDSCH를 수신하되, 상기 제 1 복조 참조 신호는 하나의 안테나 포트 상에서만 전송되며, 상기 DCI는 상기 제 2 복조 참조 신호가 매핑되는 심볼의 최대 개수 에 따라 구성이 결정되는 방법 및 장치를 제공할수 있다.
