Abstract

La présente invention concerne un procédé et un dispositif de communication. Le procédé comprend les étapes suivantes : un terminal détermine une pluralité de canaux physiques, chaque canal physique de la pluralité de canaux physiques étant transmis sur au moins certaines ressources de domaine temporel dans une unité de programmation de domaine temporel ; selon des modes d'accès multiples utilisés par au moins certains canaux physiques de la pluralité de canaux physiques, le terminal détermine la puissance d'émission desdits au moins certains canaux physiques de la pluralité de canaux physiques, les modes d'accès multiples utilisés par la pluralité de canaux physiques étant différents ; le terminal transmet, dans l'unité de programmation de domaine temporel, lesdits au moins certains canaux physiques de la pluralité de canaux physiques à l'aide de la puissance d'émission correspondant aux dits au moins certains canaux physiques de la pluralité de canaux physiques. La puissance d'émission d'un canal physique est déterminée d'après le type d'un mode d'accès multiples utilisé dans le canal physique, ce qui permet d'améliorer la flexibilité avec laquelle un terminal peut déterminer la puissance d'émission d'un canal physique.
