摘要： Disclosed are a method, network device, and system for transmit power control during D2D communication. The method comprises: a network device determines the maximum allowed transmit power of a first terminal on the basis of the maximum level of interference that a cellular network can handle and/or the maximum level of interference that the first terminal is allowed to cause to a receiving terminal, and sends said maximum allowed transmit power of the first terminal to the first terminal, said first terminal being the sending device of D2D communication; and the first terminal determines transmit power on the basis of said maximum allowed transmit power. By means of the present technical solutions, when determining transmit power, a D2D sending device takes into account the maximum interference a cellular network can handle and/or the maximum level of interference that may be caused to a receiving terminal, thereby reducing the interference caused to D2D communicating terminals or to terminals of other cells using the resources of a cellular network.
