Abstract

L'invention concerne un procédé de régulation de puissance et un dispositif terminal. Le procédé comprend : lorsque des données de liaison montante, des données sur un premier type de liaison latérale et des données sur un second type de liaison latérale se chevauchent dans le temps, et lorsque la puissance totale exigée dépasse une puissance de transmission maximale du dispositif terminal, la régulation par le terminal de la puissance de transmission des données de liaison montante, de la puissance de transmission des données sur le premier type de liaison latérale et/ou de la puissance de transmission des données sur le second type de liaison latérale. Le dispositif terminal peut attribuer de façon rationnelle la puissance de transmission du dispositif terminal en régulant la puissance de transmission des données de liaison montante, la puissance de transmission des données sur le premier type de liaison latérale et/ou la puissance de transmission des données sur le second type de liaison latérale.
