Wake-up signal scheme for wake-up management

A method implemented in a network node configured to communicate with a wireless device, the method comprising:

• configuring the wireless device according to a wake-up signal, WUS, scheme, the WUS scheme configured for at least one of:
• reducing an occurrence of a false wake-up of a main radio of the wireless device by at least one of:
• assigning the wireless device to a group of wireless devices based on a common characteristic, the wireless devices of the group being configured to wake based on receiving a WUS;
• configuring the wireless device with a first set of time-frequency resources for a first WUS, the first set of time-frequency resources being different from a second set of time-frequency resources used by another wireless device for a second WUS;
• and
• configuring the wireless device with a first wake-up radio, WUR, discontinuous reception, DRX, cycle different from a second WUR DRX cycle of the another wireless device;
• configuring the wireless device with a no-wake-up window, the no-wake-up window having a time period during which a main radio of the wireless device is prevented from waking;
• and
• configuring the wireless device with an inactivity timer configured for, after the occurrence of the false wake up, keeping the main radio awake for the duration of the inactivity timer;
• and
• communicating with the wireless device based on the WUS scheme.

A wireless device configured to communicate with a network node the wireless device comprising processing circuitry configured to:

• receive a wake-up signal, WUS, scheme, the WUS scheme configured for at least one of:
• reducing an occurrence of a false wake-up of a main radio of the wireless device by at least one of:
