Abstract

La présente invention concerne un procédé de communication et un dispositif de communication. Le procédé de communication comprend les étapes suivantes : un terminal reçoit un signal LAA et un signal WiFi au moyen d'une ressource de spectre sans licence et détermine s'il faut émettre des informations de rapport en fonction de la différence entre l'énergie du signal LAA et celle du signal WiFi ; dans une condition dans laquelle le signal WiFi impose une forte interférence au signal LAA, des informations de rapport sont transmises à un dispositif réseau utilisé pour ordonner au dispositif réseau de mettre à jour l'attribution de ressources, et dans une condition dans laquelle le signal WiFi impose moins d'interférence au signal LAA, les informations de rapport ne sont pas transmises. Le procédé permet à un dispositif réseau d'attribuer raisonnablement des ressources de telle sorte que le taux d'utilisation de ressources est amélioré et que le débit du dispositif de réseau est amélioré.
