Abstract
Embodiments of the present invention relate to a method and an apparatus for reducing transmit power. The method includes allocating initial bandwidth to all terminals scheduled in a current timeslot in a cell; calculating remaining bandwidth in the current timeslot and remaining system bandwidth; if the remaining system bandwidth is greater than preset threshold bandwidth, reducing transmit power or a frequency domain to calculate expanded bandwidth; calculating a transmit power reduction value corresponding to the terminal in a current scheduling timeslot, and a time domain system power reduction value, or a final frequency domain system power reduction value of each terminal; when the time domain system power reduction value is not less than a preset threshold, or when a final frequency domain transmit power reduction value of each terminal is not less than a preset threshold, reducing transmit power of a base station.
