Method for configuration of wake-up signaling in a radio network

A method carried out in a network node of a cellular radio network for configuring a User Equipment (UE) to monitor wake-up signal (WUS) reception in non-connected mode, wherein the method comprises:

• obtaining information related to the UE, said information being indicative of a wake-up receiver (WUR) being comprised in the UE, and indicative of associated
• timing performance of the WUR;
• configuring the UE with:
• a discontinuous reception (DRX) configuration for non-connected mode, identifying a DRX cycle of PO-based DRX Active times, and
• WUR configuration, based on the obtained information, said WUR configuration identifying resources for monitoring WUS reception at WUR Active times repeated with a WUR cycle,
• wherein the WUR cycle is 1/K times the DRX cycle, K being an integer 2:1.
