Title
(EN) METHOD AND APPARATUS FOR TRANSCEIVING UPLINK CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL POUR ÉMETTRE/RECEVOIR DES INFORMATIONS DE COMMANDE MONTANTES DANS UN SYSTÈME DE COMMUNICATION SANS FIL

Abstract
(EN) The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for reporting channel state information. A method in which a terminal transmits uplink control information (UCI) in a wireless communication system according to one embodiment of the present invention comprises: a step of determining channel state information (CSI) report timing; a step of determining acknowledgement/non-acknowledgement (ACK/NACK) information transmission timing; and a step of transmitting one or more pieces of the CSI or the ACK/NACK information via an uplink subframe. In the event that the CSI is invalid CSI, then said CSI is omitted, and only said ACK/NACK information can be transmitted via the uplink subframe.
(FR) La présente invention concerne un système de communication sans fil, et plus spécifiquement un procédé et un appareil permettant de rapporter des informations d'état de canal. Selon un mode de réalisation de la présente invention, un procédé dans lequel un terminal transmet des informations de commande montantes (UCI) dans un système de communication sans fil comprend une étape de détermination du moment de rapport d'informations d'état de canal (CSI), une étape de détermination du moment de transmission des informations d'accusé de réception/non-accusé de réception (ACK/NACK), et une étape de transmission d'une ou plusieurs parties des CSI ou des informations de ACK/NACK via une sous-trame montante. Si les CSI sont des CSI non valables, lesdites CSI sont omises, et seules les informations de ACK/NACK peuvent être transmises via une sous-trame de liaison montante.
(KO) 본 발명은 무선 통신 시스템에 대한 것으로, 보다 상세하게는 채널상태정보를 보고하는 방법 및 장치가 개시된다. 본 발명의 일 실시예에 따른 무선 통신 시스템에서 단말이 상향링크제어정보(UCI)를 전송하는 방법은, 채널상태정보(CSI)의 전송 타이밍을 결정하는 단계; 확인응답(ACK/NACK)정보의 전송 타이밍을 결정하는 단계; 및 상기 CSI 또는 상기 ACK/NACK 정보 중 하나 이상을 상향링크 서브프레임에서 전송하는 단계를 포함하고, 상기 CSI가 유효하지 않은 CSI인 경우에, 상기 CSI는 누락되고 상기 ACK/NACK 정보만이 상기 상향링크 서브프레임에서 전송될 수 있다.
