Abstract: front page image
(EN)Disclosed are a method for transmitting a reference signal in a wireless communications system and an apparatus therefor. A base station (BS) generates a channel state information (CSI) reference signal (RS) sequence, and mapping the CSI-RS sequence to at least one resource element of a special sub-frame in a TDD (time division duplex) frame by using a modulation symbol according to the CSI-RS pattern. The base station transmits the OFDM (orthogonal frequency division multiplexing) signal generated based on the mapped CSI-RS sequence to a terminal. Here the CSI-RS pattern is determined according to the configuration of the special sub-frame and CP (cyclic prefix).
(FR)La présente invention porte sur un procédé d'émission d'un signal de référence dans un système de communication sans fil et sur un appareil associé. Une station de base (BS) génère une séquence de signal de référence (RS) d'informations d'état de canal (CSI), et mappe la séquence CSI-RS à au moins un élément de ressource d'une sous-trame spéciale dans une trame de duplexage par répartition temporelle (TDD) par utilisation d'un symbole de modulation en fonction du motif CSI-RS. La station de base transmet à un terminal le signal de multiplexage par répartition orthogonale de la fréquence (OFDM) généré sur la base de la séquence CSI-RS mappée. Ici, le motif CSI-RS est déterminé en fonction de la configuration de la sous-trame spéciale et d'un préfixe cyclique (CP).
(KO)무선 통신 시스템에서 참조 신호를 전송하는 방법 및 장치가 제공된다. 기지국(BS; base station)은 채널 상태 정보(CSI; channel state information) 참조 신호(RS; reference signal) 시퀀스를 생성하고, 생성된 CSI-RS 시퀀스를 변조 심볼(modulation symbol)을 이용하여 CSI-RS 패턴에 따라 TDD(time division duplex) 프레임 내의 특별 서브프레임(special subframe)의 적어도 하나의 자원 요소에 맵핑한다. 기지국은 상기 맵핑된 CSI-RS 시퀀스를 기반으로 생성된 OFDM(orthogonal frequency division multiplexing) 신호를 단말로 전송한다. 이때 상기 CSI-RS 패턴은 상기 특별 서브프레임의 구성(configuration) 및 CP(cyclic prefix)에 따라 결정된다.
