Abstract
(EN) This user terminal comprises: a transmitting/receiving unit which transmits and receives using a first Component Carrier (CC) and a second CC that uses a numerology different from the numerology of the first CC; and a control unit which controls transmission of a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) in response to a downlink signal of the first CC by using an uplink control channel or an uplink shared channel of the first CC, and/or controls transmission of a HARQ-ACK in response to the downlink signal of the second CC using the uplink shared channel of the second CC.
(FR) L'invention concerne un terminal utilisateur comprenant : une unité d'émission/réception qui transmet et reçoit à l'aide d'une première porteuse composante (CC) et d'une seconde CC utilisant une numérologie différente de la numérologie de la première CC ; et une unité de commande qui commande la transmission d'un accusé de réception de demande de répétition automatique hybride (HARQ-ACK) en réponse à un signal de liaison descendante de la première CC à l'aide d'un canal de commande sur la liaison montante ou d'un canal partagé sur la liaison montante de la première CC, et/ou commande la transmission d'un HARQ-ACK en réponse au signal de liaison descendante de la seconde CC à l'aide du canal partagé sur la liaison montante de la seconde CC.
(JA) 本開示の一態様に係るユーザ端末は、第１ＣＣ（Component　Carrier）と、前記第１ＣＣのニューメロロジーと異なるニューメロロジーを用いる第２ＣＣと、を用いて送信及び受信を行う送受信部と、前記第１ＣＣの上り制御チャネル又は上り共有チャネルを用いて、前記第１ＣＣの下り信号に対するＨＡＲＱ－ＡＣＫ（Hybrid　Automatic　Repeat　reQuest－Acknowledgement）を送信すること、及び、前記第２ＣＣの上り共有チャネルを用いて、前記第２ＣＣの下り信号に対するＨＡＲＱ－ＡＣＫを送信すること、の少なくともいずれか一方を制御する制御部と、を有する。
