Methods and arrangements for device discovery
First Claim
1. A method executed in a wireless terminal configured for device-to-device (D2D) discovery, the method comprising:
- applying a hashing function to a control signal, wherein the control signal carries an identity and a time stamp corresponding to the control signal transmission;
encoding the control signal and the hashed control signal; and
transmitting the encoded control signal and encoded hashed control signal.

Abstract
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 wireless terminal for transmitting a control signal for enabling device-to-device, D2D, discovery, wherein the control signal carries an identity. According to one aspect, the method comprises hashing the control signal, taking a time stamp used for the control signal transmission as one input parameter, encoding the hashed control signal, and transmitting the encoded signal.
