Abstract
A methods, base station, wireless device and candidate relay device for supporting a D2D communication between a first wireless device and a second wireless device over a relay. The base station receives () from the first device an identity of a candidate relay wireless device and a first quality metric (Gq) pertaining to a first relay link between the first device and the candidate relay device and to a second relay link between the second device and the candidate relay device. The base station also obtains () a second quality metric (G12) pertaining to a D2D link between the first and second devices, and a third quality metric (G1 BS) pertaining to a cellular link between the base station and the first device. When the first quality metric (Gq) indicates a better link quality than both the second metric (G12) and the third metric (G1 BS), the base station selects () a relay mode for the D2D communication with the candidate relay device as the relay and instructs the involved devices accordingly.
