CA 2760269

The present invention relates to a transmission power control method and device. The transmission power control method for a cognitive radio device according to one embodiment of the present invention includes obtaining CR environmental information about a registered user or an unregistered user occupying an adjacent channel or an adjacent cell of a cognitive radio device, determining a transmission power value of the cognitive radio device using the CR environmental information, and generating transmission power control information including a transmission power value. According to the present invention, the reliable communication of the cognitive radio device can be guaranteed and at the same time interference for a registered user can be minimized.

L'invention concerne un procédé et un dispositif de régulation de puissance d'émission. Dans un mode de réalisation, le procédé de régulation de puissance d'émission pour un dispositif de radio cognitive consiste à obtenir des informations sur l'environnement de radio cognitive concernant un utilisateur enregistré ou un utilisateur non enregistré occupant un canal adjacent ou une cellule adjacente d'un dispositif de radio cognitive, déterminer une valeur de puissance d'émission du dispositif de radio cognitive au moyen des informations sur l'environnement de radio cognitive, et générer une information sur la régulation de puissance d'émission y compris une valeur de puissance d'émission. La présente invention permet de garantir une communication fiable du dispositif de radio cognitive et de réduire simultanément à un minimum les interférences pour un utilisateur enregistré.
