Abstract

La présente invention appartient au domaine technique des communications. Elle concerne en particulier un procédé et un dispositif d'ajustement de la puissance d'émission. L'invention vise à résoudre le problème technique lié à l'échec de la réception normale d'un signal par un équipement utilisateur lorsque l'affaiblissement du signal est important en haute fréquence. Dans les modes de réalisation de la présente invention, un équipement de réseau peut déterminer une valeur d'un facteur de mise en forme d'impulsion correspondant à l'équipement d'utilisateur, et détermine en outre une valeur d'ajustement de la puissance d'émission d'un émetteur d'après la valeur du facteur de mise en forme d'impulsion. L'invention ajuste ainsi la puissance d'émission de l'émetteur d'après la valeur d'ajustement. Autrement dit, elle ajuste la puissance d'émission d'émetteurs correspondants d'après une situation réelle de l'équipement d'utilisateur. L'invention permet en outre au signal d'être envoyé à une extrémité de réception en tenant compte autant que possible de l'affaiblissement, et améliore le taux de couverture d'une cellule.
