Abstract:
(EN) In order to perform communication properly even when the transmission timing/transmission period of retransmission control information is flexibly controlled (becomes variable), one aspect of a user terminal according to the present invention has: a transmission unit that transmits retransmission control information for DL transmission; and a control unit that controls transmission of the retransmission control information at a prescribed timing, notification of said timing having been provided from a base station, wherein a time window is set for the retransmission control information, the control unit controls the transmission of the retransmission control information on the basis of the prescribed timing and the time window that was set for the retransmission control information, and at least one instance of the prescribed timing is included in the range of the time window.
(FR) Selon la présente invention, afin de réaliser correctement une communication même lorsque le rythme de transmission/la période de transmission d'informations de commande de retransmission est commandé de manière souple (devient variable), un aspect d'un terminal d'utilisateur comprend: une unité de transmission qui transmet des informations de commande de retransmission pour une transmission DL; et une unité de commande qui commande la transmission des informations de commande de retransmission à un rythme prescrit, une notification dudit rythme ayant été fournie à partir d'une station de base, une fenêtre temporelle étant spécifiée pour les informations de commande de retransmission, l'unité de commande assurant la commande de la transmission des informations de commande de retransmission d'après le rythme prescrit et la fenêtre temporelle qui a été spécifiée pour les informations de commande de retransmission, et au moins une instance du rythme prescrit étant comprise dans l'étendue de la fenêtre temporelle.
(JA) 再送制御情報の送信タイミング/送信期間が柔軟に制御される(可変となる)場合であっても、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、DL送信に対する再送制御情報を送信する送信部と、基地局から通知された所定タイミングで前記再送制御情報の送信を制御する制御部と、を有し、前記再送制御情報に対して時間ウィンドウが設定され、前記制御部は、前記所定タイミングと前記再送制御情報に設定された時間ウィンドウとに基づいて前記再送制御情報の送信を制御し、前記所定タイミングが前記時間ウィンドウの範囲に少なくとも1回は含まれる。
