Title (EN) METHOD AND APPARATUS FOR TRANSMITTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
(FR) PROCÉDÉ ET APPAREIL DE TRANSMISSION D'INFORMATIONS D'ÉTAT DE CANAL DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선통신 시스템에서 채널 상태 정보 전송 방법 및 장치
Abstract:
(EN) The present invention relates to a method and apparatus for transmitting channel state information (CSI) on a terminal having a plurality of cells allocated in a wireless communication system. The method includes the steps of: setting a plurality of cells as a plurality of groups, at least one of the groups including a plurality of cells; determining a priority for each of the groups; and transmitting multiple pieces of CSI for a top priority group having a highest priority from among the groups on the basis of the priority, wherein, when the top priority group includes two or more cells, the CSI includes each piece of CSI on each of the two or more cells.
(FR) La présente invention porte sur un procédé et un appareil de transmission d'informations d'état de canal (CSI) sur un terminal ayant une pluralité de cellules attribuées dans un système de communication sans fil. Le procédé comprend les étapes consistant à : configurer une pluralité de cellules sous la forme d'une pluralité de groupes, au moins un des groupes comprenant une pluralité de cellules ; déterminer une priorité pour chacun des groupes ; et transmettre de multiples éléments de CSI pour un groupe de plus haute priorité ayant une priorité la plus haute parmi les groupes sur la base de la priorité. Quand le groupe de plus haute priorité comprend deux cellules ou plus, les CSI comprennent chaque élément de CSI sur chacune des deux cellules ou plus.
(KO) 무선통신 시스템에서 복수의 셀들을 할당 받은 단말의 채널 상태 정보(channel state information: CSI) 전송 방법 및 장치를 제공한다. 상기 방법은 상기 복수의 셀들을 복수의 그룹들로 설정하되, 상기 복수의 그룹들 중 적어도 하나의 그룹은 복수개의 셀들을 포함하고, 상기 그룹들 각각에 대한 우선 순위를 결정하고, 및 상기 우선 순위에 기반하여 상기 그룹들 중 가장 높은 우선 순위를 가지는 최우선 그룹에 대한 다중 CSI를 전송하되, 상기 다중 CSI는 상기 최우선 그룹에 2 이상의 셀들이 포함된 경우, 상기 2 이상의 셀들 각각에 대한 CSI들을 포함하는 것을 특징으로 한다.
