FORWARD LINK POWER CONTROL IN CELLULAR SYSTEM USING NT/IO VALUES

摘要

PROBLEM TO BE SOLVED: To provide forward link power control in a cellular system using NT/IOValues. SOLUTION: The mobile station determines a signal strength value according to a communication signal received by way of the communication channel. A pilot channel signal is determined according to a pilot signal transmitted by way of the pilot channel. The signal-to-noise ratio of the communication signal is determined according to the determined signal strength value and the pilot channel signal. The power level of a transmission is controlled according to the signal-to-noise ratio. The pilot channel signal includes pilot energy component and pilot noise component. This pilot noise component is removed to provide a remaining pilot signal. Communication system operations are controlled according to the remaining pilot signal. The power levels of transmissions are controlled by determining the signal-to-noise ratio of a signal within the communication channel and determining a difference signal. The difference signal is formed by determining the difference between determined and desired signal-to-noise ratios. COPYRIGHT: (C)2009,JPO&INPIT
