(FR) TERMINAL UTILISATEUR ET PROCÉDÉ DE COMMUNICATION RADIO
(JA) ユーザ端末及び無線通信方法
Abstract:
(EN) This user terminal is characterized by being provided with a transmission unit which transmits UL data without UL transmission instructions from a radio base station, and a control unit which performs repeat transmissions of the UL data on the basis of the number of repeat transmissions, wherein, on the basis of the radio resource type assigned to the aforementioned repeat transmissions, the control unit controls whether or not to count the number of repeat transmissions. By this means, repeat transmissions are suitably performed without a UL grant, making it possible to improve radio transmission performance and reliability.
(FR) La présente invention concerne un terminal utilisateur qui est caractérisé en ce qu'il est pourvu d'une unité de transmission qui transmet des données UL sans instructions de transmission UL en provenance d'une station de base radio, et d'une unité de commande qui effectue des transmissions répétées des données UL sur la base du nombre de transmissions répétées. Sur la base du type de ressource radio attribué aux transmissions répétées susmentionnées, l'unité de commande commande s'il faut compter ou non le nombre de transmissions répétées. Par ce moyen, des transmissions répétées sont réalisées de manière appropriée sans autorisation UL, ce qui permet l'amélioration des performances et de la fiabilité en matière de transmission radio.
(JA) 一態様に係るユーザ端末は、無線基地局からのUL送信指示なしにULデータを送信する送信部と、繰り返し送信数に基づいて、前記ULデータの繰り返し送信を行う制御部と、を備え、前記制御部は、前記繰り返し送信に割り当てられた無線リソースタイプに基づいて、繰り返し送信数をカウントするか否かを制御することを特徴とする。このような一態様によれば、ULグラントフリーで繰り返し送信を適切に行い、無線通信のパフォーマンス及び信頼性を向上することができる。
