METHOD FOR CONTROLLING TRANSMISSION POWER OF A MOBILE TERMINAL, PARTICULARLY FOR COMPENSATING A TEMPERATURE OF TRANSMISSION POWER WITH A MAXIMUM TRANSMISSION POWER AUTOMATIC GAIN CONTROL VALUE TO BE CONTROLLED ACCORDING TO A TEMPERATURE CHANGE OF EVERY MOBILE TERMINAL

摘要

PURPOSE: A method for controlling transmission power of a mobile terminal is provided to compensate maximum transmission power suitable for RF characteristics different for each mobile terminal by calculating a temperature compensation value for compensating an error of a maximum transmission power control signal according to a temperature change. CONSTITUTION: A maximum transmission power AGC(Automatic Gain Control) value according to a temperature change of a specific mobile terminal is measured and an offset of the maximum transmission power AGC value is calculated. Transmission power AGC value of every mobile terminal to be manufactured is measured and a maximum transmission power AGC value of all the measured transmission power AGC values and a corresponding measured temperature are extracted. A temperature compensation value at a room temperature is calculated through the measured temperature and the extracted maximum transmission power AGC value. The maximum transmission power AGC value is compensated with the calculated temperature compensation value of each temperature.
