The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for implementing a direct device-to-device communication of cellular devices, e.g., in LTE wireless systems, using discovery or discovery-like signaling To enable automatic discovery of other devices, a dedicated channel may be reserved for this purpose where devices may send a specific discovery signal with a predefined format, so that other devices listening in this channel can know the existence of the transmitters. For example, the discovery signal may be generated by one device for establishing a direct device-to-device communication, the discovery signal comprising a preamble part and a data part which comprises information for establishing the direct device-to-device communication, wherein a preamble resource for the preamble part is determined from a set of predefined resources and a data resource for the data part maps form the preamble resource. |
