Abstract

The present invention provides a device and method for limiting the maximum output of each transmission channel of a mobile communication terminal. The method includes: detecting the output power of the signal, and when the detected output power deviates from the range of the threshold value, calculating the difference between the detected output power and the output power previously stored in the terminal, and multiplying the calculated difference by a predetermined number value to store the resulting value and transmit the signal with the stored power value. Therefore, the output power of each transmission channel is controlled so that communication quality can be improved without interference.

Description

technical field [0001] The present invention relates to a mobile communication terminal, in particular to a device and method for limiting the maximum output of each channel of the mobile communication terminal. Background technique [0002] Generally, according to the 3rd Generation Partnership Project (3GPP) specification, a code division multiple access (CDMA) based mobile communication terminal includes 16 channels. A mobile communication terminal (hereinafter referred to as a terminal) includes a power meter having 16 power levels for 16 channels, and a lookup table illustrating analog-to-digital converter (ADC) values ​​corresponding to the power levels. For example, when there are 9739 transmission channels in 3GPP, the power table includes 16 power levels from 6.75dBm-26.67dBm with a difference of 1.33dBm from each other, and the ADC value corresponds to each power level (for example, 96, when the power level is 6, 75dBm, and 100, when the power level is 8.08dBm). ...
