Abstract
A method and apparatus for saving power during punctured transmission in a CDMA mobile communication system. The apparatus comprises a baseband device, a mixed signal portion, a radio frequency (RF) frontend and a power supply. The baseband device comprises a variable rate voice coder (vocoder) which reduces the rate of voice data transmission to the mixed signal portion when voice activity by a user is low during a two-way conversation. When the rate of voice data transmission is reduced, there are one or more periods in which no voice data is transmitted. The system provides a signal from the baseband device to power OFF certain portions of the mixed signal portion during the periods of transmission with no voice data. This reduces the amount of power consumed by the mixed signal portion and enhances the life of the power supply.
