The present invention discloses a transmit power control method and a device in D2D communication. A network device in the present invention determines and delivers control information, where the control information includes first subframe information and a first power control manner in which power control is performed in a first subframe corresponding to the first subframe information, and second subframe information and a second power control manner in which power control is performed in a second subframe corresponding to the second subframe information. A user equipment in D2D communication acquires the control information delivered by the network device; transmits, by using the transmit power determined according to the first power control manner, a D2D signal in the first subframe corresponding to the first subframe information; and transmits, by using the transmit power determined according to the second power control manner, a D2D signal in the second subframe corresponding to the second subframe information. By means of the present invention, interference from a D2D signal to an uplink signal received by the network device can be restricted, thereby improving accuracy of receiving the uplink signal by the network device. |
