Transmission rate control method, mobile station, radio base station, and radio network controller

A transmission rate control method for controlling transmission rate of layer-2 control information, comprising:

• notifying, at a radio network controller, a correspondence of a transmission data block size of an upper layer flow to a transmission power ratio between an enhanced dedicated physical data channel and a dedicated physical control channel on the upper layer flow, to a mobile station;
• controlling, at the mobile station, the correspondence per upper layer flow;
• notifying, at the radio network controller, an upper layer flow identifier to the mobile station;
• determining, at the mobile station, a transmission power ratio of the layer-2 control information to be transmitted, based on the correspondence which corresponds to the notified upper layer identifier;
• and
• transmitting, at the mobile station, the layer-2 control information using the determined transmission power ratio.

• determining, at the mobile station, a transmission power ratio of the layer-2 control information to be transmitted, based on the correspondence of a upper layer flow which has a highest priority level;
• and
• transmitting, at the mobile station, the layer-2 control information using the determined transmission power ratio.
