Abstract: A method for transmitting, by a first relay user equipment (UE), signals by considering interferences in a further enhancement D2D (FeD2D) environment comprises the steps of: calculating, by the first relay UE, a distance to a virtual remote user equipment (UE) located on a straight line between the first relay UE and a second relay UE; determining an allowable interference intensity for the virtual remote UE, on the basis of a predetermined target signal to interference and noise ratio (SINR) value for the virtual remote UE and an intensity of a received signal from the second relay UE of the virtual remote UE; determining a transmission power on the basis of the allowable interference intensity and the calculated distance; and comparing the determined transmission power with a minimum transmission power that satisfies the target SINR, wherein the virtual remote UE may be located at a threshold of a target range of the second relay UE.
