  • Patent number: 11832186
    Abstract: Some of the present implementations provide a method for a user equipment (UE) for receiving a power saving signal. The method receives, from a base station, a power saving signal comprising a minimum applicable K0 (K0min) that indicates a minimum scheduling offset restriction between a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDCCH). The method determines an application delay based on a predefined value. The method then applies the minimum scheduling offset restriction after the application delay.
