Abstract

La présente invention concerne un procédé de commande de transmission de puissance électrique dans un environnement de connexion multiple, et un dispositif électronique l'utilisant. Un procédé pour faire fonctionner le dispositif électronique peut comprendre les opérations consistant à : détecter la proximité d'un utilisateur par l'intermédiaire d'un module de capteur (par exemple, un module de capteur (176) de la FIG. 1) ; déterminer si des signaux RF sont reçus à l'aide d'au moins deux bandes de fréquence en réponse à la proximité de l'utilisateur ayant été détectée ; déterminer la puissance électrique maximale disponible du signal RF transmis à partir du module d'antenne sur la base d'une première valeur de réduction de puissance électrique, lorsqu'il est déterminé que les signaux RF sont reçus à l'aide d'une bande de fréquence ; et déterminer la puissance électrique maximale disponible du signal RF transmis à partir du module d'antenne sur la base d'une seconde valeur de réduction de puissance électrique inférieure à la première valeur de réduction de puissance électrique, lorsqu'il est déterminé que les signaux RF sont reçus à l'aide d'au moins deux bandes de fréquence. Grâce au procédé décrit ci-dessus, le TRP d'un dispositif de communication sans fil peut être amélioré et les performances de liaison montante peuvent être renforcées.
