INNER-LOOP POWER CONTROL METHOD FOR WCDMA MOBILE TERMINAL

摘要

Disclosed is an inner-loop power control method for a WCDMA mobile terminal, including: generating from a first power threshold value to a second power threshold value a plurality of first radio frequency signals and detecting same so as to obtain a plurality of first power values; generating from the second power threshold value to the first power threshold value a plurality of second radio frequency signals and detecting same so as to obtain a plurality of second power values; determining a power difference of an adjacent first power value and a power difference of an adjacent second power value approximate to a gain mode switching point; determining a first inter-segment difference and a second inter-segment difference according to the power difference so as to obtain an inter-segment compensation value, a first switching point compensation value and a second switching point compensation value; using the inter-segment compensation values to compensate the first power value and the second power value in a certain gain mode, and using the first switching point compensation value and the second switching point compensation value to compensate the first power value and the second power value approximate to the switching point. The above method can improve power control performance and make same meet specification requirements.
