Title (EN) METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION D'INFORMATIONS D'ÉTAT DE CANAL
(KO) 채널 상태 정보 전송 방법 및 장치
Abstract: front page image
(EN)The present invention relates to a method for transmitting channel state information of a terminal in a multi-carrier system, and to a terminal using the method. The method comprises the steps of: receiving reference signals from a base station via a plurality of downlink component carriers; measuring a channel state for each of the plurality of downlink component carriers using the reference signals included in the plurality of downlink component carriers; generating channel state information on a portion of the plurality of downlink component carriers; and transmitting to the base station the channel state information on a portion of the plurality of downlink component carriers and/or an index which indicates the portion of the plurality of downlink component carriers.
(FR)La présente invention porte sur un procédé dans lequel un terminal transmet des informations d'état de canal (CSI) dans un système multiporteuse, et sur un terminal qui utilise le procédé. Le procédé comprend les étapes suivantes : réception de signaux de référence en provenance d'une station de base (BS) par l'intermédiaire d'une pluralité de porteuses composantes de liaison descendante ; mesure d'un état de canal pour chacune des porteuses composantes de liaison descendante à l'aide des signaux de référence inclus dans chacune des porteuses composantes de liaison descendante ; génération d'informations d'état de canal sur une partie de la pluralité de porteuses composantes de liaison descendante ; et transmission d'au moins un des éléments d'informations d'état de canal sur une partie de la pluralité de porteuses composantes de liaison descendante et d'un indice qui indique la partie de la pluralité de porteuses composantes de liaison descendante.
(KO)다중 반송파 시스템에서 단말의 채널 상태 정보 전송 방법 및 상기 방법을 이용하는 단말을 제공한다. 상기 방법은 기지국으로부터 복수의 하향링크 요소 반송파를 통해 참조 신호를 수신하는 단계; 상기 복수의 하향링크 요소 반송파 각각에 포함된 참조 신호를 이용하여 상기 복수의 하향링크 요소 반송파 각각에 대한 채널 상태를 측정하는 단계; 상기 복수의 하향링크 요소 반송파 중에서 일부 하향링크 요소 반송파에 대한 채널 상태 정보를 생성하는 단계; 및 상기 일부 하향링크 요소 반송파에 대한 채널 상태 정보 및 상기 일부 하향링크 요소 반송파를 지시하는 인덱스 중 적어도 하나를 상기 기지국으로 전송하는 단계를 포함하는 것을 특징으로 한다.
