Abstract:
(EN) A method for transmitting uplink control information for a terminal supporting a plurality of transmission time intervals (TTI), a plurality of subcarrier intervals, or a plurality of processing times in a wireless communication system according to an embodiment of the present invention is carried out by the terminal and comprises: a step of mapping uplink control information to a radio resource in a TTI configured with two or three symbols, the uplink control information including hybrid automatic retransmission request-acknowledgement (HARQ-ACK)/non-acknowledgement, a rank indicator (RI), a channel quality indicator (CQI) or a precoding matrix indicator (PMI); and a step of transmitting the uplink control information to a base station, wherein, if there is no symbol, in the TTI, to which a DMRS is mapped, the HARQ-ACK may be mapped to the first symbol in the TTI in descending order from the highest frequency index resource element (RE), and the RI may be mapped to the remaining symbol(s) in the TTI in descending order from the highest frequency index RE.
(FR) L'invention concerne un procédé de transmission d'informations de commande de liaison montante pour un terminal prenant en charge une pluralité d'intervalles de temps de transmission (TTI), une pluralité d'intervalles de sous-porteuse, ou une pluralité de temps de traitement dans un système de communication sans fil. Un mode de réalisation de la présente invention est mis en œuvre par le terminal et comprend : une étape consistant à mettre en correspondance des informations de commande de liaison montante à une ressource radio dans un TTI configuré avec deux ou trois symboles, les informations de commande de liaison montante comprenant un accusé de réception de demande de retransmission automatique hybride (HARQ-ACK)/non accusé de réception, un indicateur de rang (RI), un indicateur de qualité de canal (CQI) ou un indicateur de matrice de précodage (PMI) ; et une étape de transmission des informations de commande de liaison montante à une station de base, où, s'il n'y a pas de symbole, dans le TTI, selon lequel un DMRS est mis en correspondance, le HARQ-ACK peut être mis en correspondance avec le premier symbole dans le TTI en ordre décroissant à partir de l'élément de ressource d'indice de fréquence le plus élevé (RE), et le RI peut être mis en correspondance avec le(s) symbole(s) restant(s) dans le TTI en ordre décroissant à partir de l'indice de fréquence le plus élevé RE.
(KO) 본 발명의 일 실시예에 따른 무선 통신 시스템에서 복수의 TTI(transmission time interval) 길이, 복수의 서브캐리어 간격 또는 복수의 프로세싱 시간을 지원하는 단말을 위한 상향링크 제어 정보 전송 방법에 있어서, 상기 방법은 단말에 의해 수행되며, 2개 또는 3개 심볼로 구성된 TTI에서 무선 자원에 상향링크 제어 정보를 맵핑하는 단계, 상기 상향링크 제어 정보는 HARQ-ACK(hybrid automatic retransmission request-acknowledgement/non-acknowledgement), 랭크 지시자(rank indicator; RI), 채널 품질 지시자(channel quality indicator; CQI) 또는 프리코딩 행렬 지시자(precoding matrix indicator; PMI)를 포함하고; 및 상기 상향링크 제어 정보를 기지국으로 전송하는 단계를 포함하고, 상기 TTI 내에 DMRS가 맵핑되는 심볼이 없는 경우, 상기 TTI 내 첫번째 심볼에 HARQ-ACK이 가장 높은 주파수 인덱스 자원 요소(resource element; RE)부터 내림차순으로 맵핑되고, RI는 상기 TTI 내 나머지 심볼에 가장 높은 주파수 인덱스 RE부터 내림차순으로 맵핑될 수 있다.
