Abstract
The invention provides a power control method and device. In the method, RRUs in a cell are grouped, and different powers are distributed to areas covered with the RRUs in different groups. By means of the power control method and device, the power of each covered area can be separately controlled according to the covering demanding requirement of each area. Thus, the high power is configured to the covered areas (intelligent antenna covered areas) with a high requirement for the power, meanwhile the low power is configured to the covered areas (special scene covered areas) with a low requirement for the power, and week covering is avoided while interference between the RRU-covered areas is avoided. Meanwhile, because the low power is configured to the covered areas with the low requirement for the power, meaningless resource waste is avoided.
