A first network node for managing a transmit power of a first wireless device that is capable of device-to-device, D2D, communication, the network node comprising a processor and a memory containing instructions whereby, when the instructions are executed by said processor, the first network node is operable to:
- receive at least one measurement report from at least one of the first wireless device and a second wireless device in D2D communication with the first wireless device, the measurement report indicating a received signal measurement or path loss with respect to the other of the first wireless device and the second wireless device and/or a received signal measurement or path loss with respect to a victim node;
- and
- send the first wireless device instructions to make an adjustment of the transmit power that the first wireless device uses in the D2D communication, wherein the adjustment is at least partially based on the received measurement report.
