Title (EN) USER TERMINAL AND WIRELESS COMMUNICATIONS METHOD
(FR) TERMINAL D'UTILISATEUR, ET PROCÉDÉ DE COMMUNICATIONS SANS FIL
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) This user terminal is characterized by having: a transmission unit that uses an uplink control channel resource in a prescribed bandwidth part (BWP) and sends uplink control information; and a control unit that determines the correspondence between said uplink control channel resource and a prescribed index, on the basis of prescribed information, and specifies the uplink control channel resource. As a result of the present invention, reduction in communication throughput can be suppressed even when performing control on the basis of BWP.
(FR) L'invention concerne un terminal d'utilisateur caractérisé en ce qu'il comprend : une unité de transmission qui utilise une ressource de canal de commande de liaison montante dans une partie de bande passante (BWP) prescrite, et envoie des informations de commande de liaison montante ; et une unité de commande qui détermine la correspondance entre ladite ressource de canal de commande de liaison montante et un indice prescrit, sur la base d'informations prescrites, et spécifie la ressource de canal de commande de liaison montante. La présente invention peut supprimer une réduction du débit de communication même lorsqu'une commande est exécutée sur la base d'une BWP.
(JA) 本発明の一態様に係るユーザ端末は、所定の帯域幅部分(BWP:Bandwidth part)において上り制御チャネルリソースを用いて上り制御情報を送信する送信部と、前記上り制御チャネルリソースと所定のインデックスとの対応関係を所定の情報に基づいて判断し、前記上り制御チャネルリソースを特定する制御部と、を有することを特徴とする。本発明の一態様によれば、BWPに基づく制御を行う場合であっても、通信スループットの低下などを抑制できる。
