Methods and arrangements for device discovery
First Claim
1. A method executed in a first wireless terminal for transmitting a control signal enabling device-to-device (D2D) discovery, wherein the control signal carries an identity, the method comprising:
- 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.

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 first 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.
