  • Publication number: 20230007580
    Abstract: Systems and methods allow access stations to save power when no user equipment (UE) devices require service from the access station. The access station may enter a low power-consumption mode (or “sleep mode”) when the access station is inactive. The access station transmits a beacon signal when in the low power-consumption mode to indicate to UE devices in a coverage area of the access station that the access station is in the low power-consumption mode. The access station receives a wake-up signal from a device and, in response, exits the low power-consumption mode.
