The invention discloses a method for power adjustment and relates to the field of communication technology. Average network experience of micro-station service users can be effectively improved. The method comprises steps that a micro base station obtains a corresponding service macro community; the micro base station counts first signal strength difference between micro communities fed back by different grades of users and the service macro community serviced by the micro base station; the micro base station calculates the ratio value of first target users to all users in the user grade to which the first target users belong, wherein the first target users are the micro base station users whose fist signal strength difference values are lower than the interference threshold; and when the ratio is higher than the adjustment threshold, the micro base station adjusts emission power. The method is applicable in power adjustment processes of base stations.
