Abstract
Embodiments of the present invention provide a power control method and a device. The method comprises the steps of acquiring the residual power of a terminal by a base station; on the condition that the base station judges the residual power is larger than or equal to a first preset residual power, comparing the modulating and coding scheme (MCS) of the terminal with a MCS threshold value; on the condition that the MCS is smaller than the MCS threshold value, increasing the transmitting power of the terminal by a first preset power; otherwise, keeping the transmitting power of the terminal to be unchanged. The MCS threshold value is smaller than the highest order of the MCS. Therefore, the inter-cell interference caused by the power control divergence of a near-point terminal can be reduced. The fairness of terminals in the same cell or in neighboring cells can be ensured, so that terminals in the same cell or in neighboring cells can be successfully accessed to the internet.
