摘要
PROBLEM TO BE SOLVED: To provide a forward link power control in a cellular system using NT/IO values for evaluating a relative amount of power given onto a traffic channel using the calculation amount of a noise existing on a pilot channel.;SOLUTION: A mobile station determines signal intensity according to a communication signal received via a communication channel. A pilot channel signal is determined according to a pilot signal transmitted via the pilot channel. The signal-to-noise ratio of the communication signal is determined according to the determined signal intensity and the pilot channel signal. The transmission power level is controlled according to the signal-to-noise ratio. The pilot channel signal includes a pilot energy and pilot noise component. The pilot noise component is removed to provide remaining pilot signals. Communication system operation is controlled according to the remaining pilot signals. The transmission power level is controlled by the communication channel and determination of the signal-to-noise ratio of the signal in the determined difference signal. The difference signal is formed by determining the difference between the determined signal-to-noise ratio and the desired signal-to-noise ratio.;COPYRIGHT: (C)2011,JPO&INPIT
