Abstract
(EN) Provided is a communication method for a terminal in a multi-carrier system using a plurality of component carriers. The method comprises the following steps: receiving a reconfiguration message which indicates whether downlink control information (DCI) contains a carrier indication field (CIF); receiving a plurality of downlink control information which indicates a resource to be used for the transmission of a reconfiguration completion message as a response to the reconfiguration message; and transmitting the reconfiguration completion message on resource allocation information contained in the downlink control information which has been successfully decoded from among the plurality of downlink control information, wherein the plurality of downlink control information contain first downlink control information which exists before the carrier indication field configuration of the downlink control information is changed by the reconfiguration message, and second downlink control information which is obtained after the carrier indication field configuration of the downlink control information is changed by the reconfiguration message.
(FR) L'invention porte sur un procédé de communication d'un terminal, dans un système à plusieurs porteuses utilisant une pluralité de porteuses composantes. Le procédé comporte les étapes suivantes : la réception d'un message de reconfiguration qui indique si des informations de commande de liaison descendante (DCI) contiennent ou non un champ d'indication de porteuse (CIF) ; la réception d'une pluralité d'informations de commande de liaison descendante qui indiquent une ressource devant être utilisée pour la transmission d'un message d'achèvement de reconfiguration en réponse au message de reconfiguration, et l'envoi du message d'achèvement de reconfiguration concernant les informations d'attribution de ressources contenues dans les informations de commande de liaison descendante qui ont été décodées avec succès parmi la pluralité d'informations de commande de liaison descendante. La pluralité d'informations de commande de liaison descendante contiennent les premières informations de commande de liaison descendante qui existent avant la modification de la configuration de champ d'indication de porteuse des informations de commande de liaison descendante par le message de reconfiguration, et les secondes informations de commande de liaison descendante qui sont obtenues après la modification de la configuration de champ d'indication de porteuse des informations de commande de liaison descendante par le message de reconfiguration.
(KO) 복수의 요소 반송파를 사용하는 다중 반송파 시스템에서 단말의 통신 방법을 제공한다. 상기 방법은 하향링크 제어정보(downlink control information, DCI)에 반송파 지시 필드(carrier indication field, CIF)가 포함되는지 여부를 지시하는 설정 변경 메시지를 수신하는 단계; 상기 설정 변경 메시지에 대한 응답인 설정 변경 완료 메시지 전송에 사용되는 자원을 지시하는 복수의 하향링크 제어정보를 수신하는 단계; 및 상기 복수의 하향링크 제어정보 중 디코딩에 성공한 하향링크 제어정보에 포함된 자원할당정보에 기반하여 상기 설정 변경 완료 메시지를 전송하는 단계를 포함하되, 상기 복수의 하향링크 제어정보는 상기 설정 변경 메시지에 의해 하향링크 제어정보의 반송파 지시 필드 설정이 변경되기 전의 제1 하향링크 제어정보 및 상기 설정 변경 메시지에 의해 하향링크 제어정보의 반송파 지시 필드 설정이 변경된 후의 제2 하향링크 제어정보를 포함하는 것을 특징으로 한다.
