Abstract
(EN)
This user device comprises: a transmission unit which performs transmission to another user device via a control channel and a data channel; a reception unit which receives, from the other user device, a hybrid automatic repeat request (HARQ) response to the transmission; and a control unit which notifies the other user device of information related to the resource of the channel for receiving the HARQ response, and performs a retransmission control related to the transmission on the basis of the HARQ response.
(FR)
La présente invention concerne un dispositif d’utilisateur comprenant : une unité de transmission qui réalise une transmission vers un autre dispositif d’utilisateur via un canal de commande et un canal de données ; une unité de réception qui reçoit, en provenance de l’autre dispositif d’utilisateur, une réponse de demande de répétition automatique hybride (HARQ) à la transmission ; et une unité de commande qui notifie à l’autre dispositif d’utilisateur des informations concernant la ressource du canal pour recevoir la réponse HARQ, et réalise une commande de retransmission concernant la transmission sur la base de la réponse HARQ.
(JA)
ユーザ装置は、他のユーザ装置に制御チャネル及びデータチャネルを介して送信を行う送信部と、前記送信に対するHARQ(Hybrid automatic repeat request)応答を前記他のユーザ装置から受信する受信部と、前記HARQ応答を受信するチャネルのリソースに係る情報を前記他のユーザ装置に通知し、前記HARQ応答に基づいて前記送信に係る再送制御を行う制御部とを有する。
