(EN) COMMUNICATION DEVICE AND COMMUNICATION METHOD
(FR) DISPOSITIF DE COMMUNICATION ET PROCÉDÉ DE COMMUNICATION
(JA) 通信装置及び通信方法
Abstract
(EN) A communication device comprising: a reception unit that receives data over a sidelink shared channel; a control unit that creates delivery confirmation information for the received data; and a transmission unit that, if a first elapsed time period from when the reception unit receives the data to the timing at which to transmit the delivery confirmation information by sidelink communication is less than a first reference time period, delays the timing at which to transmit the delivery confirmation information by sidelink communication until the first elapsed time period is greater than or equal to the first reference time period.
(FR) L'invention concerne un dispositif de communication qui comprend : une unité de réception qui reçoit des données sur un canal partagé de liaison latérale ; une unité de commande qui crée des informations de confirmation de distribution pour les données reçues ; et une unité de transmission qui, si une première période de temps écoulée entre le moment où l'unité de réception reçoit les données et le moment auquel transmettre les informations de confirmation de distribution par communication de liaison latérale est inférieure à une première période de temps de référence, retarde le moment auquel transmettre les informations de confirmation de distribution par communication de liaison latérale jusqu'à ce que la première période de temps écoulée soit supérieure ou égale à la première période de temps de référence.
(JA) サイドリンクの共有チャネルでデータを受信する受信部と、前記受信したデータの送達確認情報を作成する制御部と、前記受信部が前記データを受信してから前記送達確認情報をサイドリンクで送信するタイミングまでの第一の経過時間が第一の基準時間未満であった場合に、前記第一の経過時間が前記第一の基準時間以上となるまで、前記送達確認情報のサイドリンクでの送信のタイミングを遅らせる送信部と、を備える通信装置。
