Embodiments of the present invention disclose a power control method and apparatus, where the method includes: performing a slow fading evaluation on an uplink channel of a UE to obtain a slow fading value of the uplink channel; comparing the slow fading value with a target slow fading value to obtain a first comparison result; generating, according to the first comparison result, first control signaling of a downlink control channel corresponding to the uplink channel, where the first control signaling is used to instruct the UE to adjust transmit power of the UE on the uplink channel; and sending the first control signaling to the user equipment UE. In the embodiments of the present invention, making full use of power efficiency, improving a cell throughput, and reducing neighboring cell interference.
