1. A method by a first network node for adapting transmit configuration of a first user equipment, UE, for communications directly to a second UE, the method comprising:

  • obtaining a first timing measurement between the first UE and the first network node;

    obtaining a second timing measurement between the second UE and a second network node;

    adapting the transmit configuration that includes a transmit power level of a wireless communication from the first UE directly to the second UE based on the first timing measurement between the first UE and the first network node and the second timing measurement between the second UE and the second network node; and

    transmitting a message containing information instructing the first UE to perform device-to-device direct communications with the second UE using the transmit configuration to control the transmit power level at which the first UE will transmit to the second UE.
