Title
(EN) TRANSMISSION POWER CONTROL FOR A RADIO BASE STATION
(FR) COMMANDE DE PUISSANCE DE TRANSMISSION DESTINÉE À UNE STATION DE BASE RADIOÉLECTRIQUE
Abstract
(EN)
There is provided mechanisms for controlling total average transmission power of a radio base station over a fixed time period. A method is performed by a control device. The method comprises obtaining values of average total transmission power of at least one previous transmission from the radio base station. The method comprises determining a resource factor value from the value of average total transmission power and a set point value of the average total transmission power. The method comprises determining, based on the resource factor value, an action that restricts the amount of code-division multiple access (CDMA) resources to be used at least for a current transmission. The method comprises controlling the total average transmission power over the fixed time period by initiating the determined action at least for the current transmission.

L'invention concerne des mécanismes de commande de la puissance de transmission moyenne totale d'une station de base radioélectrique sur une période de temps fixe. Un procédé est effectué par un dispositif de commande. Le procédé comprend l'obtention de valeurs de puissance de transmission totale moyenne d'au moins une transmission précédente en provenance de la station de base radioélectrique. Le procédé comprend la détermination d'une valeur de facteur de ressource à partir de la valeur de puissance de transmission totale moyenne et d'une valeur de point défini de la puissance de transmission totale moyenne. Le procédé comprend la détermination, en fonction de la valeur de facteur de ressource, d'une action qui limite la quantité de ressources d'accès multiple par répartition en code (CDMA) à utiliser au moins pour une transmission en cours. Le procédé comprend la commande de la puissance de transmission moyenne totale sur la période de temps fixe par le lancement de l'action déterminée au moins pour la transmission en cours.
