Abstract:
1. A transmission rate control method for controlling a transmission rate of uplink user data, comprising: notifying, from a radio network controller, to a mobile station, information for determining an increasing relative transmission rate step size corresponding to each transmission rate of the uplink user data, when setting, with the mobile station, a user data channel connection for transmitting the uplink user data; and increasing, at the mobile station, the transmission rate of the uplink user data in accordance with the increasing relative transmission rate step size corresponding to a current transmission rate of the uplink user data, when receiving, from a radio base station, a relative rate control channel for indicating that the transmission rate of the uplink user data should be increased, wherein an increasing relative transmission rate step size is a step size of transmission rate of the uplink user data to be changed based on a relative grant command in the relative rate control channel.
