A method and a wireless device (110) for managing a set of resources for transmission of data to a further wireless device (120) using D2D communication are disclosed. The wireless device (110) and the further wireless device (120) are capable of being operated in a mixed cellular and D2D radio network (100). The set of resources are comprised in a cellular spectrum of the mixed cellular and D2D radio network (100). The wireless device (110) selects, from among the set of resources, a sub set of resources for the transmission of data according to a hopping algorithm for distribution of the sub set of resources among the set of resources. Then, the wireless device (110) sends a scheduling command to the further wireless device (120). The scheduling command indicates the selected sub set of resources. The wireless device (110) sends the data to the further wireless device (120) on the selected sub set of resources using D2D communication.
