Proposed are a power control method and a power control device for terminal device-to-device communications, a parameter transmission method and a parameter transmission device, and a base station and a terminal. The power control method comprises: determining at least one terminal which is outside a base station coverage range and interferes with a base station; acquiring, by the base station, signal strength information about a measurement signal sent by each terminal of the at least one terminal when the measurement signal reaches the base station, and configuring a corresponding power control parameter for each terminal according to the signal strength information; and sending, by the base station, the corresponding power control parameter of each terminal to a synchronization source terminal within the base station coverage range corresponding to each terminal, so as to send the power control parameter to a corresponding terminal by the synchronization source terminal, so that each terminal conducts power control using the corresponding power control parameter. By means of the technical solution of the present invention, power control can be conducted on a terminal which is outside a base station coverage range and interferes with a base station, so that the interference of the terminal on a signal received by the base station is reduced. |
