Title (EN) METHOD FOR TRANSMITTING/RECEIVING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
(FR) PROCÉDÉ PERMETTANT DE TRANSMETTRE/RECEVOIR UN SIGNAL DE RÉFÉRENCE DANS UN SYSTÈME DE COMMUNICATION SANS FIL ET DISPOSITIF S'Y RAPPORTANT

Abstract:
(EN) The present invention relates to a method and a device for transmitting/receiving a reference signal by means of a terminal in a wireless communication system. According to the present invention, a method and a device may be provided whereby a terminal receives downlink control information from a base station, and on the basis of the downlink control information, receives a demodulation reference signal (DMRS) and downlink data via a plurality of antenna ports. The terminal demodulates the downlink data on the basis of the DMRS, wherein the downlink data is received in the same symbol as, or in a different symbol from the DMRS according to the number of symbols associated with the downlink data.
(FR) La présente invention se rapporte à un procédé et à un dispositif permettant de transmettre/recevoir un signal de référence au moyen d'un terminal dans un système de communication sans fil. Selon la présente invention, un procédé et un dispositif peuvent être fournis, grâce auxquels un terminal reçoit des informations de commande de liaison descendante en provenance d'une station de base, et, sur la base des informations de commande de liaison descendante, reçoit un signal de référence de démodulation (DMRS pour DeModulation Reference Signal) et des données de liaison descendante par le biais d'une pluralité de ports d'antenne. Le terminal démodule les données de liaison descendante sur la base du signal DMRS, les données de liaison descendante étant reçues dans le même symbole que le signal DMRS, ou dans un symbole différent de ce dernier, en fonction du nombre de symboles associés aux données de liaison descendante.
(KO) 무선 통신 시스템에서 단말에 의해서 참조신호(Reference Signal)을 송수신하는 방법 및 장치에 관한 것이다. 본 발명에 의하면, 단말은 기지국으로부터 하향링크 제어 정보(Downlink Control Information)을 수신하고, 상기 하향링크 제어 정보에 기초하여 복수의 안테나 포트들을 통해 복조 참조 신호(Demodulation Reference Signal: DMRS) 및 하향링크 데이터를 수신한다. 단말은 상기 복조 참조 신호에 기초하여 상기 하향링크 데이터를 복조하되, 상기 하향링크 데이터는 상기 하향링크 데이터와 관련된 심볼의 개수에 따라 상기 복조 참조 신호와 동일한 심볼 또는 서로 다른 심볼에서 수신되는 방법 및 장치를 제공할 수 있다.
