Title:
MOBILE STATION TRANSMISSION POWER CONTROL METHOD
Document Type and Number:
Japanese Patent JP3165660
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a transmission power control method which can always and automatically control reception and transmission power in an optimum state.
SOLUTION: An output of an IF amplifier 14 and a limiter 16 is converted into direct voltage DV by a logarithmic amplifier 18, and a control part 22 measures the reception power (RSSI) of the mobile station by using this and decides and controls transmission power from the measured result. The method calculates and adjusts the transmission power from the mean value of reception power for a prescribed time, the transmission power of a base station which is analyzed by a packet transmitted by the base station and reception power that is desired by the base station. The transmission power is decided by adding the value, which subtracted the mean value of the reception power from the transmission power of the base station, to the reception power that is desired by the base station during the subscribing procedure. A 1st stage where present transmission power is decided by adding the value which subtracted the mean value of the reception power from the transmission power of the base station to the reception power, which is desired by the base station and a 2nd stage where the present transmission power, is adjusted according to the change width between previous transmission power and the present transmission power are performed after the subscribing procedure.
