Abstract

L'invention concerne un procédé et un appareil permettant de réguler une puissance radiofréquence. Le procédé permettant de réguler une puissance radiofréquence comprend les étapes suivantes consistant à : transmettre les uns après les autres plusieurs signaux de confirmation à un terminal de réception de telle manière que la puissance de transmission soit réduite ou accrue une par une ; et déterminer une puissance de transmission de signal en se basant sur le fait que la réception des signaux de rétroaction renvoyés par le terminal de réception correspond, ou non, aux signaux de confirmation. Le procédé et l'appareil de la présente invention permettant de réguler la puissance radiofréquence transmettent les signaux de confirmation de telle manière que la puissance de transmission soit réduite ou accrue une par une, et déterminent la puissance de transmission de signal pendant une interaction sur la base des signaux de rétroaction reçus correspondant aux signaux de confirmation. L'efficacité de la communication peut être garantie et, en même temps, la consommation d'énergie d'un dispositif de commande à distance est efficacement réduite.
