Abstract:
(EN) In order to suitably perform transmission of a control channel when communicating applying a configuration different from in existing LTE systems, this user terminal is provided with a receiving unit which receives a downlink control channel transmitted using a downlink control channel element (CCE) configured from a prescribed number of resource element groups (REGs), and a control unit which controls reception of the aforementioned control channel. An REG group is configured from multiple REGs, and if a downlink control channel is transmitted using multiple time domains, then the control unit controls reception under the assumption that 1 CCE includes REGs of at least different time domains and the REGs with the different time domains are included in different REG groups.
(FR) Selon l'invention, afin de réaliser de manière appropriée la transmission d'un canal de commande lors d'une communication appliquant une configuration différente de celle des systèmes LTE existants, un terminal utilisateur est pourvu d'une unité de réception qui reçoit un canal de commande de liaison descendante transmis à l'aide d'un élément de canal de commande de liaison descendante (CCE) configuré à partir d'un nombre prescrit de groupes d'éléments de ressource (REG), et d'une unité de commande qui commande la réception du canal de commande susmentionné. Un groupe REG est configuré à partir de multiples REG, et si un canal de commande de liaison descendante est transmis à l'aide de multiples domaines temporels, l'unité de commande commande la réception dans l'hypothèse où 1 CCE comprend des REG d'au moins différents domaines temporels et les REG assortis des différents domaines temporels sont inclus dans différents groupes REG.
(JA) 既存のLTEシステムと異なる構成を適用して通信を行う場合に、制御チャネルの通信を適切に行うために、本発明のユーザ端末の一態様は、所定数のリソースエレメントグループ(REG)で構成される下り制御チャネル要素(CCE)を利用して送信される下り制御チャネルを受信する受信部と、前記下り制御チャネルの受信を制御する制御部と、を有し、複数のREGでREGグループが構成され、下り制御チャネルが複数の時間領域を利用して送信される場合、前記制御部は、1CCEが少なくとも異なる時間領域のREGを含み、前記異なる時間領域のREGが異なるREGグループに含まれると想定して受信を制御する。
