Abstract: front page image
(EN)The present invention provides a method by which a terminal measures channel state information (CSI), a method by which a terminal transmits CSI, and devices for supporting the methods. A method by which a terminal feeds back CSI in a wireless access system, according to one embodiment of the present invention, can comprise the steps of: receiving an upper layer signal including a channel quality indicator (CQI) index; receiving a physical downlink control channel (PDCCH) signal including an aperiodic CSI request field; receiving a physical downlink shared channel (PDSCH) signal that is repeatedly transmitted as many time as the number indicated by the CQI index; measuring the CSI for a CSI reference resource; and feeding back the measured CSI by using a physical uplink shared channel (PUSCH) signal.
(FR)La présente invention concerne un procédé à l’aide duquel un terminal mesure des informations d’état de canal (CSI), un procédé à l’aide duquel un terminal transmet les CSI, et des dispositifs pour mettre en œuvre les procédés. Un procédé à l’aide duquel un terminal fournit en retour des CSI dans un système d’accès sans fil, selon un mode de réalisation de la présente invention, peut comprendre les étapes suivantes : la réception d’un signal de couche supérieure incluant un indice d’indication de qualité de canal (CQI) ; la réception d’un signal de canal de commande de liaison descendante physique (PDCCH) incluant un champ de requête de CSI apériodique ; la réception d’un signal de canal partagé de liaison descendante physique (PDSCH) qui est transmis de manière répétitive autant de fois que le nombre indiqué par l’indice de CQI ; la mesure des CSI pour une ressource de référence de CSI ; et la fourniture des CSI mesurées à l’aide d’un signal de canal partagé de liaison montante physique (PUSCH).
(KO)본 발명은 단말이 채널상태정보(CSI)를 측정하는 방법 및 CSI를 송신하는 방법 및 이를 지원하는 장치들을 제안한다. 본 발명의 일 실시예로서 무선접속시스템에서 단말이 채널상태정보(CSI)를 피드백하는 방법은, 채널품질정보(CQI) 인덱스를 포함하는 상위 계층 신호를 수신하는 단계와 비주기적 CSI 요청 필드를 포함하는 물리하향링크제어채널(PDCCH) 신호를 수신하는 단계와 CQI 인덱스가 지시하는 개수만큼 반복 전송되는 물리하향링크공유채널(PDSCH) 신호를 수신하는 단계와 CSI 참조 자원에 대해서 CSI를 측정하는 단계와 측정한 CSI를 물리상향링크공유채널(PUSCH) 신호를 이용하여 피드백하는 단계를 포함할 수 있다.
