description The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.
