Abstract In methods and devices for use in a radio base station of a cellular radio system, where the radio base station is arranged to control the power transmitted in the uplink by a user equipment by transmitting power control commands in the downlink to the user equipment striving to keep the received uplink Signal-to-interference Ratio, SIR, at a given SIR target, the power transmitted is controlled by transmitting transmit power control commands in the downlink striving to keep the received uplink Signal-to-interference Ratio, SIR, at a corrected SIR target. The corrected SIR target can be a SIR target supplemented by a corrective term. Selon l'invention, dans des procédés et des dispositifs destinés à être utilisés dans une station de base radio d'un système radio cellulaire, la station de base radio étant conçue pour commander la puissance émise en liaison montante par un équipement utilisateur par envoi d'instructions de commande de puissance en liaison descendante à l'équipement utilisateur visant à maintenir le rapport signal sur brouillage, SIR, de liaison montante reçu à un SIR cible donné, la puissance émise est commandée par envoi d'instructions de commande de puissance d'émission en liaison descendante visant à maintenir le rapport signal sur brouillage, SIR, de liaison montante reçu à un SIR cible corrigé. Le SIR cible corrigé peut être un SIR cible complété par un terme correctif.
