Abstract
(EN)
The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time synchronization groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS).

L'invention porte sur un procédé consistant à classifier des cellules d'équipement utilisateur (UE), auquel une agrégation de porteuses est appliquée, en une pluralité de groupes de synchronisations temporelles. Une synchronisation temporelle de liaison montante est gérée à l'aide de la synchronisation temporelle d'une cellule primaire (Pcell) dans le groupe de synchronisations temporelles auquel la cellule primaire appartient. Pour d'autres groupes de synchronisations temporelles, la synchronisation temporelle de liaison montante est gérée à l'aide de la synchronisation temporelle d'une cellule secondaire (Scell) qui est en particulier réglée dans le groupe de synchronisations temporelles pertinent. Ainsi, la pluralité de synchronisations temporelles peuvent être efficacement gérées pour l'UE et une station de base (BS).

본 발명은 반송파 병합이 구성된 사용자기기(UE)의 셀(Cell)들을 복수의 시간동기 그룹으로 구분하고, 주 셀(Primary Cell, PCell)이 속한 시간동기 그룹은 주 셀의 시간동기를 이용하여 상향링크 시간동기를 관리하고, 그 외 시간동기 그룹은 해당 시간동기 그룹에서 특별히 설정된 보조 셀(Secondary Cell, SCell)의 시간동기를 이용하여 상향링크 시간동기를 관리한다. 이에 따라, UE와 기지국(BS)는 상기 UE에 대해 복수의 시간동기가 효율적으로 관리할 수 있다.
