Title (EN) METHOD AND DEVICE FOR SENDING AND RECEIVING A REFERENCE SIGNAL
(FR) PROCÉDÉ ET DISPOSITIF POUR ENVOYER ET RECEVOIR UN SIGNAL DE RÉFÉRENCE
(KO) 기준 신호 송수신 방법 및 장치
Abstract: front page image
(EN)The present invention relates to a method for sending and receiving a reference signal for a backhaul subframe in a wireless communication system in which a relay is present and also to a device therefor, constituted in such a way that common reference signals for a plurality of receiving devices and reference signals dedicated to separate receiving devices are allocated dispersed in a subframe, and the common reference signals and the dedicated reference signals are generated and are sent and received via the subframe. The present invention can improve the channel estimation performance for subframes in a wireless communication system. In this way, communications efficiency in wireless communication systems can be improved.
(FR)La présente invention concerne un procédé pour envoyer et recevoir un signal de référence pour une sous-trame de liaison terrestre dans un système de communication sans fil dans lequel un relais est présent. L'invention concerne également un dispositif associé, constitué de sorte que des signaux de référence communs pour une pluralité de dispositifs de réception et des signaux de référence dédiés à des dispositifs de réception séparés soient attribués de manière dispersée dans une sous-trame, et les signaux de référence communs et les signaux de référence dédiés sont générés, envoyés et reçus par l'intermédiaire de la sous-trame. La présente invention peut améliorer la performance d'estimation de canal pour des sous-trames dans un système de communication sans fil. De cette manière, l'efficacité des communications dans des systèmes de communication sans fil peut être améliorée.
(KO)본 발명은 릴레이가 존재하는 무선 통신 시스템에서 백홀 서브프레임을 위한 기준 신호 송수신 방법 및 이를 위한 장치에 관한 것으로서, 서브프레임에서 다수개의 수신 장치들을 위한 공통 기준 신호들과 수신 장치 별 전용 기준 신호들을 분산시켜 할당하고, 공통 기준 신호들과 전용 기준 신호들을 생성하여 서브프레임을 통해 송신하도록 구성된다. 본 발명에 따르면, 무선 통신 시스템에서 서브프레임의 채널 추정 성능을 향상시킬 수 있다. 이를 통해, 무선 통신 시스템에서 통신 효율성을 향상시킬 수 있다.
