要約
(EN) The present invention is designed so that multiple UL signals of varying RATs are transmitted properly in non-stand-alone radio communication systems. A user terminal has a transmission section that transmits a first uplink (UL) signal of a first radio access technology (RAT) and a second UL signal of a second RAT, at different times, and a control section that controls switching between a first time, which is used to transmit the first UL signal using a first UL carrier of the first RAT, and a second time, which is used to transmit the second UL signal using a second UL carrier of the second RAT.
(FR) La présente invention concerne l'envoi, de manière appropriée, d'une pluralité de signaux de liaison montante (UL) de différentes technologies d'accès radio (RAT) dans un système de communication sans fil de type non autonome. Un terminal d'utilisateur comprend : une unité d'émission pour émettre un premier signal UL d'une première RAT et un second signal UL d'une seconde RAT à différents moments ; et une unité de commande pour commander la commutation d'un premier moment utilisé pour l'émission du premier signal UL dans laquelle une première porteuse UL de la première RAT est utilisée, et d'un second moment utilisé pour l'émission du second signal UL dans laquelle une seconde porteuse UL de la seconde RAT est utilisée.
