Abstract

Certains modes de réalisation de la présente demande concernent des procédés de communication sans fil, un dispositif terminal et un dispositif de communication, un procédé consistant à : déterminer, sur la base de premières informations, la puissance de transmission d'un dispositif terminal sur de multiples porteuses, les premières informations comprenant au moins une caractéristique parmi les caractéristiques suivantes : au moins une première valeur de seuil correspondant à au moins une première porteuse parmi les multiples porteuses, une seconde valeur de seuil appropriée pour les multiples porteuses, la perte de propagation spatiale du dispositif terminal, ou les premières informations d'instruction utilisées pour ordonner au dispositif terminal de régler la puissance de transmission sur les multiples porteuses ; et envoyer des données de liaison montante sur la base de la puissance de transmission sur les multiples porteuses. En introduisant les premières informations et en déterminant, sur la base des premières informations, la puissance de transmission du dispositif terminal sur les multiples porteuses, il est possible d'éviter autant que possible que la puissance de transmission sur certaines porteuses parmi les multiples porteuses soit trop élevée ou trop faible, et d'éviter ainsi d'abandonner des porteuses, et de manière correspondante, d'améliorer le débit et la fiabilité de la transmission de données.
