Patent ID: 7756543

Claim:
A method for regulating the transmit power level of a data transmission over a high speed shared radio channel in a cell in a radio communications system, comprising: determining an available amount of power that can potentially be used for the high speed radio transmission; determining a variable power increase factor that controls a rate at which the transmit power level for a high speed data transmission over the high speed shared radio channel can increase; setting the power level of the high speed data transmission based on the determined variable power increase factor; and transmitting data over the high speed data transmissions channel based on the set power level, wherein the power level of the high speed data transmission is determined in accordance with the following: P HS =P tx *F−P non-HS where P HS is the power available for the high speed data transmission channels in the cell, P tx is the total transmit power in the last subframe in the cell and P non-HS is the power used for non-high speed data communications in the cell, and F is the variable power increase factor.
