Abstract

La présente invention concerne un procédé et un appareil de transmission d'informations, et un support d'enregistrement. Le procédé comprend les étapes suivantes : une unité de bande de base génère des premières informations, les premières informations permettant d'indiquer une première unité radio à distance pour arrêter l'exécution d'une première opération lorsque la valeur d'énergie d'un premier signal de liaison montante correspondant à la première unité radio à distance est inférieure à une première valeur prédéfinie, la première opération comprenant une transmission en liaison montante et/ou une transmission en liaison descendante, et la première unité radio à distance constituant l'une quelconque d'une pluralité d'unités radio à distance d'un dispositif de réseau ; et la première unité radio à distance reçoit les premières informations et, selon les premières informations, arrête l'exécution de la première opération lorsque la valeur d'énergie du premier signal de liaison montante correspondant à la première unité radio à distance est inférieure à la première valeur prédéfinie. Par conséquent, lorsque la première unité radio à distance ne dispose pas d'un utilisateur ou d'un utilisateur valide, la présente invention permet de garantir que la première unité radio à distance arrête l'exécution de la première opération, ce qui permet de réduire le nombre d'unités radio à distance participant à une combinaison de fréquences radio, de réduire le bruit de fond de liaison montante et d'améliorer les performances de transmission du système.
