Abstract

Dans la présente invention, une ou plusieurs transmissions UL dans lesquelles un réglage de priorité est pris en charge sont commandées de manière appropriée. Un terminal selon un aspect de la présente divulgation comprend : une unité de réception qui reçoit des informations concernant la priorité des transmissions UL ; et une unité de commande qui, lorsque des transmissions UL ayant des priorités différentes se chevauchent dans un domaine temporel, détermine, sur la base d'informations de commande de liaison descendante, s'il faut transmettre les transmissions UL ayant les différentes priorités en utilisant le même canal UL.
