A method for outer loop power control in a wireless communication system begins by determining if a cyclic redundancy check (CRC) is available. If the CRC is available, the method uses the CRC to calculate an adjustment for a target signal to interference ratio (SIR) for a coded composite transport channel (CCTrCH). If the CRC is not available, then quality measurements of the CCTrCH are taken. The quality measurements are used to calculate an adjustment for the target SIR, which is then updated.

L'invention concerne un procédé de commande de puissance à boucle extérieure d'un système de communication sans fil, selon lequel il est prévu dans un premier temps de déterminer si un contrôle de redondance cyclique (CRC) est disponible. Si ledit CRC est disponible, le procédé fait appel audit CRC pour calculer un ajustement d'un signal cible à un niveau d'interférence (SIR) pour un canal de transport composite codé (CCTrCH). Si le CRC n'est pas disponible, des mesures de qualités du CCTrCH sont alors effectuées. Les mesures de qualité sont utilisées pour calculer un ajustement du SIR cible qui est ensuite actualisé.
