Abstract
(EN)
Provided are a method for controlling the transmission power of a terminal, and a terminal. The method and the terminal can monitor working states of a first antenna and a second antenna, then control transmission powers of the first antenna and the second antenna according to a pre-set correlation. Accordingly, the method and the terminal can accurately control the transmission power of whichever of the first and the second antennas is in a working state. If the transmission power is less than a standard transmission power, it may serve to reduce the SAR.
(FR)
L'invention concerne un procédé pour réguler la puissance de transmission d'un terminal, et un terminal. Le procédé et le terminal peuvent surveiller des états de travail d'une première antenne et d'une seconde antenne, puis réguler des puissances de transmission de la première antenne et de la seconde antenne en fonction d'une corrélation prédéfinie. En conséquence, le procédé et le terminal peuvent réguler avec précision la puissance de transmission, indépendamment du fait que la première antenne ou la seconde antenne est dans un état de travail. Si la puissance de transmission est inférieure à une puissance de transmission standard, elle peut servir à réduire le SAR.
