Abstract

A method and base station (800) for supporting Device-to-Device, D2D, communication over a D2D radio link between a first wireless device (D1) and a second wireless device (D2). The base station (800) obtains a first path gain (G12) of the D2D radio link, a second path gain (G1) of a cellular radio link between the base station (800) and the first wireless device (D1), and a third path gain (G2) of a cellular radio link between the base station (800) and the second wireless device (D2). The base station (800) then applies a D2D communication mode with network coding for the D2D communication when the first, second and third path gains (G12,G1,G2) satisfy a threshold condition.
