CA 2679823

Aspects describe controlling a power level for an access terminal in a wireless communication system that utilizes multiple modulation waveforms. The power can be controlled after an Access Grant is received in response to an Access Probe until the mobile device transitions into a steady state. A reference power can be continuously monitored and a setting of a power amplifier can be modified only when the reference power changes. A digital gain of a reverse data channel can be adjusted relative to the reference power level.

L'invention concerne la commande d'un niveau de puissance pour un terminal d'accès dans un système de communication sans fil qui utilise de multiples formes d'onde de modulation. La puissance peut être commandée après réception d'un accord d'accès en réponse à une sonde d'accès jusqu'à ce que le dispositif mobile passe en régime permanent. Une puissance de référence peut être surveillée en continu et un réglage de l'amplificateur de puissance peut être modifié uniquement lorsque la puissance de référence change. Un gain numérique d'un gain de données inverse peut être ajusté par rapport au niveau de puissance de renversement.
