A method and a base station are provided. The base station obtains a first path gain of a cellular radio link to a first wireless device, a second path gain of a cellular radio link to a second wireless device and a third path gain of a Device-to-Device radio link between the first wireless device and the second wireless device. When the first, second and third path gains satisfy a threshold condition, the base station instructs the second wireless device to apply network coding on first data transmitted from the first wireless device and to transmit a network coded form of the first data. The base station receives a radio signal with the first data transmitted from the first wireless device and uses the network coded form of the first data transmitted by the second wireless device for decoding the first data.
