Title: Method for controlling forward power in a CDMA-2000 system
Inventor: LEE JEONG HAN
IPC: H04B7/26
Filed: 2002-08-30
Abstract: PURPOSE: A method for controlling a forward power in a CDMA(Code Division Multiple Access)-2000 system is provided to effectively control the power by dividing 16 reverse power control sub-channel information into 4 portions and controlling the power with respect to each channel. CONSTITUTION: If forward power control is started, a base station transmits information of a channel for performing inner loop estimation and a correspondence channel to an MS(Mobile Station)(100). The MS(100) receives channel information and the correspondence channel transmitted from the base station, and measures a channel-classified signal-to-noise ratio(S201-S203). The MS(100) decides a channel-classified target signal-to-noise ratio(S204). The MS(100) applies a new forward power control mode(S205). The MS(100) calculates a reception power level difference value between the channel which performs the inner loop estimation and a channel which does not perform the inner loop estimation, and compares the calculated difference value with a predetermined threshold value(S206). If the difference value is greater than the threshold value, the MS(100) performs the inner loop estimation of all channels and transmits power control sub-channels of all channels to the base station(S207,S208). If the difference value is less than the threshold value, the MS(100) performs the inner loop estimation with respect to only the decided channel and transmits a power control sub-channel of the decided channel to the base station(S209,S210). The base station receives the power control sub-channel transmitted from the MS(100), and controls a forward power on the basis of the received power control sub-channel.
