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.
Claims11
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.
A first wireless terminal adapted for transmitting a control signal enabling device-to-device (D2D) discovery, wherein the control signal carries an identity, the first wireless terminal comprising:
- processing circuitry adapted to cause the wireless terminal to hash the control signal, taking a time stamp used for the control signal transmission as one input parameter;
- baseband circuitry adapted to encode the hashed control signal;
- and
- transmit circuitry adapted to transmit the encoded signal.
A non-transitory computer-readable medium comprising, stored thereupon, a computer program comprising computer readable code that, when run on a wireless terminal, causes the wireless terminal to:
- hash a control signal enabling device-to-device (D2D) discovery, wherein the control signal carries an identity, taking a time stamp used for the control signal transmission as one input parameter to the hashing of the control signal;
- encode the hashed control signal;
- and
- transmit the encoded signal.
