Abstract

To control QoS for each mobile station UE while minimizing the affect on radio capacity in the downlink, a transmission rate control method of the present invention comprises: receiving, at a mobile station, a common absolute transmission rate control signal used for a common transmission rate control and a dedicated relative transmission rate control signal used for a dedicated transmission rate control; and setting, at the mobile station, a higher one of a first transmission rate indicated by the common absolute transmission rate control signal and a second transmission rate determined based on the dedicated relative transmission rate control signal, as a transmission rate in an uplink.

Claims

1. A transmission rate control method comprising:

receiving, at a mobile station, a common absolute transmission rate control signal used for a common transmission rate control and a dedicated relative transmission rate control signal used for a dedicated transmission rate control; and

setting, at the mobile station, a higher one of a first transmission rate indicated by the common absolute transmission rate control signal and a second transmission rate determined based on the dedicated relative transmission rate control signal, as a transmission rate in an uplink.

2. A mobile station comprising:

a receiver section configured to receive a common absolute transmission rate control signal used for a common transmission rate control and a dedicated relative transmission rate control signal used for a dedicated transmission rate control;

a comparing section configured to compare a first transmission rate indicated by the common absolute transmission rate control signal and a second transmission rate determined based on the dedicated relative transmission rate control signal; and

a setting section configured to set a higher one of the first transmission rate and the second transmission rate, as a transmission rate in an uplink.
