Abstract:
(EN) The present invention relates to a method and apparatus for a terminal to report channel state information (CSI) in a wireless communication system. According to the present invention, the terminal may receive configuration information related to the CSI from the base station and may measure the CSI on the basis of the configuration information. Thereafter, a method and apparatus may be provided, the method comprising a step of the terminal reporting the measured CSI to the base station, wherein the CSI is configured with a first part and a second part, the first part includes a rank indicator (RI), a channel quality indicator (CQI), and an indicator indicating the number of non-zero amplitude coefficients, and the second part includes a precoding matrix indicator (PMI).
(FR) La présente invention concerne un procédé et un appareil permettant à un terminal de communiquer un rapport d'informations d'état de canal (CSI) dans un système de communication sans fil. Selon la présente invention, le terminal peut recevoir des informations de configuration concernant les CSI provenant de la station de base et peut mesurer les CSI en fonction des informations de configuration. Ensuite, l'invention concerne un procédé et un appareil, le procédé comprenant une étape consistant à communiquer, par le terminal, un rapport des CSI mesurées à la station de base, les CSI étant configurées avec une première partie et une deuxième partie, la première partie contenant un indicateur de rang (RI), un indicateur de qualité de canal (CQI), et un indicateur indiquant le nombre de coefficients d'amplitude non nuls, et la deuxième partie contenant un indicateur de matrice de précodage (PMI).
(KO) 무선 통신 시스템에서 단말이 채널 상태 정보 (Channel State Information: CSI)를 보고하는 방법 및 장치에 관한 것이다. 본 발명에 의하면, 단말은 기지국으로부터 CSI와관련된 구성 정보를 수신하고, 상기 구성 정보에 기초하여 CSI를 측정할 수 있다. 이후, 단말은 상기 측정된 CSI를 상기 기지국으로 보고하는 단계를 포함하되, 상기 CSI는 제 1 파트 및 제 2 파트로 구성되고, 상기 제 1 파트는 랭크 지시자 (Rank Indicator: RI), 채널 품질 지시자 (channel quality indicator: CQI) 및 0이 아닌 진폭 계수의 수를 나타내는 지시자를 포함하고, 상기 제 2 파트는 프리코딩 행렬 지시자 (precoding matrix indicator: PMI)를 포함하는 방법 및 장치를 제공할수 있다.
