Abstract

La présente invention concerne un procédé d'optimisation de puissance pour un terminal et un dispositif. Le procédé comprend les étapes suivantes : un appareil terminal détermine des premières informations en fonction d'une ou plusieurs informations de service de support, d'informations de niveau de batterie, ou d'informations de qualité de canal d'une cellule de desserte ; et l'appareil terminal envoie les premières informations à un appareil de réseau, les premières informations indiquant au moins l'un des éléments suivants : une capacité de porteuse prise en charge par l'appareil terminal, un mode de modulation supporté par l'appareil terminal, une capacité radiofréquence prise en charge par l'appareil terminal, une capacité de transmission de liaison descendante prise en charge par l'appareil de terminal, une capacité de transmission de liaison montante prise en charge par l'appareil terminal, et un paramètre pour effectuer une transmission discontinue (DRX) de l'appareil terminal. La solution technique fournie par la présente invention permet d'obtenir une optimisation de puissance d'un appareil terminal (par exemple, UE) pendant un processus de communication, ce qui permet de réduire la consommation d'énergie de l'appareil terminal.
