Method and apparatus for controlling radio frequency exposure of wireless device, and wireless device

An apparatus for controlling radio frequency exposure of a wireless device, wherein the apparatus comprises:

• an obtaining system configured to obtain an average radio frequency exposure value over a target time window corresponding to a controlled time window, wherein the target time window is a standard time window, wherein a start moment of the controlled time window is an end moment of the target time window, and wherein duration of the controlled time window is shorter than duration of the standard time window;
• and
• a processor configured to:
• store a preset correspondence between a preset value range of the average radio frequency exposure value and a preset power based on an application scenario;
• and
• control a transmit power of the wireless device based on a power threshold over the controlled time window such that the average radio frequency exposure value of the wireless device in any standard time window is less than or equal to a standard radio frequency exposure value, wherein the power threshold is based on the stored preset correspondence.
