Title (EN) USER TERMINAL AND WIRELESS COMMUNICATION METHOD
(FR) TERMINAL UTILISATEUR ET PROCÉDÉ DE COMMUNICATION SANS FIL
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) The user terminal according to one aspect of the present disclosure is characterized by comprising: a reception unit that receives downlink control information; a transmission unit that transmits an uplink signal on the basis of the downlink control information; and a control unit that changes interpretation of a specific field included in the downlink control information on the basis of whether or not a waveform applied to the uplink signal has been specified. According to the one aspect of the present disclosure, deterioration of the communication throughput can be suppressed even when a plurality of waveforms are switched and used.
(FR) La présente invention concerne, selon un aspect, un terminal utilisateur comprenant : une unité de réception qui reçoit des informations de commande de liaison descendante ; une unité d'émission qui émet un signal de liaison montante en fonction des informations de commande de liaison descendante ; et une unité de commande qui change l'interprétation d'un champ spécifique compris dans les informations de commande de liaison descendante selon qu'une forme d'onde appliquée au signal de liaison montante a été ou non spécifiée. Selon un aspect de la présente invention, la détérioration du débit de communication peut être supprimée même lorsque plusieurs formes d'onde sont commutées et utilisées.
(JA) 本開示の一態様に係るユーザ端末は、下り制御情報を受信する受信部と、下り制御情報に基づいて上り信号を送信する送信部と、前記上り信号に適用する波形が指定済みか否かに基づいて、前記下り制御情報に含まれる特定のフィールドの解釈を変更する制御部と、を有することを特徴とする。本開示の一態様によれば、複数の波形を切り替えて利用する場合であっても、通信スループットの低下を抑制できる。
