Abstract
There is disclosed a method for operating a wireless device (10), the wireless device (10) being D2D enabled. The method comprises entering, by the wireless device (10), an energy-saving mode; monitoring, by the wireless device (10), a pre-defined channel for a D2D wake-up signal at pre-defined times during the energy-saving mode; determining, by the wireless device (10), if a received wake-up signal is intended for the wireless device; and performing, by the wireless device (10), a wake-up procedure for D2D communication. There are also disclosed related devices and methods.

1-6. (canceled)
A method for operating a wireless device, the wireless device being enabled for device-to-device (D2D) operation, wherein the method comprises:
- entering, by the wireless device, an energy-saving mode;
- monitoring, by the wireless device, a pre-defined channel for a D2D wake-up signal at pre-defined times during the energy-saving mode;
- determining, by the wireless device, whether a received wake-up signal is intended for the wireless device;
- and
- performing, by the wireless device, a wake-up procedure for D2D communication.
A wireless device for a wireless communication network, the wireless device being enabled for device-to-device (D2D) operation, wherein the wireless device comprises:
- a control circuit;
- and
- memory operatively connected to the control circuit and storing program code executable by the control circuit, whereby the wireless device is configured to:
- enter an energy-saving mode;
- monitor a pre-defined channel for a D2D wake-up signal at pre-defined times during the energy-saving mode;
- determine whether a received wake-up signal is intended for the wireless device;
- and
- perform a wake-up procedure for D2D communication.
A non-transitory computer-readable medium comprising, stored thereupon, a code executable by control circuitry of a wireless device enabled for device-to-device (D2D) operation, the code causing the control circuitry to control the wireless device to:
- enter an energy-saving mode;
- monitor a pre-defined channel for a D2D wake-up signal at pre-defined times during the energy-saving mode;
- determine whether a received wake-up signal is intended for the wireless device;
- and
- perform a wake-up procedure for D2D communication.
