The present disclosure relates to methods and devices for transmission of discovery signal signals and detection of discovery signal signals for device-to-device communication. According to some aspects, the disclosure relates to a method executed in a second wireless terminal for discovering a first wireless terminal, wherein the second wireless terminal 20 is configured with a set of one or more identities of wireless terminals with which device-to-device, D2D, communication is possible. The method comprises the following steps detecting a control signal transmitted from the first wireless terminal, wherein the control signal carries an identity and decoding S13 the received signal. The wireless terminal then, for each identity in the set, hashes S14 a reference control signal comprising an identity of the wireless terminal, taking a time stamp used for the control signal transmission as one input parameter of the hashing function and determines S15 if an output signal of the hashing matches the decoded signal, until all the identities in the set have been selected or until a match is found. |
