Abstract

Un terminal selon un aspect de la présente divulgation comprend : une unité de réception qui reçoit des informations d'instruction ; et une unité de commande qui détermine des informations de commande pour déterminer la puissance d'émission d'une pluralité de signaux de liaison montante sur la base des informations d'instruction. Les types de canaux sont différents parmi la pluralité de signaux de liaison montante, ou les faisceaux sont différents parmi la pluralité de signaux de liaison montante. En variante, les types de canaux et les signaux de référence sont différents parmi la pluralité de signaux de liaison montante, et les faisceaux sont différents parmi la pluralité de signaux de liaison montante. Selon un aspect de la présente divulgation, la puissance d'émission d'une pluralité de signaux de liaison montante peut être déterminée de manière appropriée.
