The communication terminal apparatus measures reception quality and reports the measurement result to the base station apparatus, and the base station apparatus switches the transmission rate based on the reported result of the reception quality. In this way, the transmission rate is switched starting at the point in time at which the reception quality of the communication terminal apparatus deteriorates. Furthermore, the transmission rate is switched so that the amount of interference with others is within the allowable range according to the channel condition between the communication terminal apparatus and base station apparatus.
Selon la présente invention, un terminal de réseau mesure la qualité de la réception et transmet les résultats de la mesure à une station de base. La station de base commute la vitesse de transmission sur la base des résultats qui lui ont été transmis. Lorsque la qualité de réception du terminal de réseau diminue, la vitesse de transmission est commutée. La vitesse de transmission est également commutée dans le but de faire tomber les interférences avec une autre transmission dans une plage acceptable en fonction de l'état du canal reliant le terminal de réseau et la station de base.
