Transmission power levels of uplink/downlink communication is controlled in a wireless communication system. A receiving station produces and provides to a transmitting station power control information based upon received signals from the transmitting station. A measured block error rate (BLERmsr) is obtained from the number of erroneous blocks in a sliding window of the last N received data blocks and SIR adjustments are set based upon the BLERmsr and a target BLER (BLERtarget). A target SIR of received signals is adjusted according to the SIR adjustments.
La présente invention concerne la régulation de la puissance d'émission des communications descendantes et remontantes dans un système de radiocommunications. Une station réceptrice produit et fournir à une station émettrice de l'information de commande de puissance sur la base des signaux reçus de la station émettrice. Un taux mesuré d'erreur de blocs (BLER¿msr?) est déduit du nombre de blocs en erreur dans une fenêtre coulissante des N derniers blocs de données reçus, et on définit des corrections du rapport signal/parasites (SIR) sur la base du paramètre BLER¿msr? et d'un rapport BLER cible (BLER¿target?). Un rapport SIR cible des signaux reçus est corrigé en fonction des corrections de rapport SIR.
