A communication terminal device comprising: measure means for measuring the reception quality of a control channel signal transmitted by a base station device; and receive means for receiving a data channel signal transmitted by the base station device under a modulation system and an encoding system decided by the base station device. These modulation system and encoding system are decided by the base station device on the basis of the reception quality of the control channel signal, as measured by the measure means, and the transmission power values of the control channel signal and the data channel signal in the base station device.
L'invention concerne un terminal de communication qui comprend un dispositif de mesure pour mesurer la qualité de réception d'un signal d'un canal de commande transmis par une station de base, et un dispositif de réception pour recevoir un signal d'un canal de commande transmis par la station de base sous l'effet d'un système de modulation et d'un système de codage activés par la station de base. Le système de modulation et le système de codage sont activés par la station de base en fonction de la qualité de réception du signal du canal de commande, tel qu'il est mesuré par le dispositif de mesure, et en fonction de valeurs de puissance d'émission du signal du canal de commande et du signal de canal de données dans la station de base.
