  • METHOD, DEVICE AND COMPUTER STORAGE MEDIUM FOR COMMUNICATION
    Publication number: 20250203521
    Abstract: Embodiments of the present disclosure relate to method, device and computer storage medium for low power (LP) wake-up signal (WUS) monitoring. A terminal device switches on a receiver of the terminal device to monitor a WUS without performing radio resource control (RRC) actions corresponding to RRC idle/inactive process. The terminal device further starts a timer associated with the WUS. If the timer expires, the terminal device performs the RRC actions and switches off the receiver. In this way, the terminal device can decide when to perform the RRC actions and switch off the receiver based on the timer. In this way, the terminal device can acknowledge the situation of connection with a network.
