Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif terminal pour la compression d'une puissance de transmission. Le dispositif terminal transmet des données via une pluralité de porteuses, une ressource de canal de chacune des porteuses comprenant au moins un premier canal, le premier canal étant utilisé pour transmettre un service de données sur le dispositif terminal. Le procédé comprend les étapes suivantes : le dispositif terminal détermine une première porteuse parmi les porteuses si une première puissance de transmission totale du dispositif terminal est supérieure à une puissance de transmission maximale autorisée du dispositif terminal, la première puissance de transmission totale étant la somme des puissances de transmission définies par le dispositif terminal pour chacune des porteuses, et la première porteuse étant la porteuse dont la puissance de transmission est la plus élevée parmi les porteuses ; et le dispositif terminal compresse un facteur de gain du premier canal de la première porteuse. Le procédé et le dispositif terminal fournis par les modes de réalisation de la présente invention peuvent améliorer la capacité de compression d'une puissance de transmission.
