  • Publication number: 20210345455
    Abstract: A device may operate within a specified frequency band within a specified coverage area of a wireless cellular network served by a cell. The device may monitor, during a cell-specific paging window, paging messages transmitted by the cell within the cell-specific paging window to devices operating within the specified coverage area and targeted to receive paging messages. The device may enter an idle state if the monitoring indicates that the paging messages do not include a respective paging message intended for the device. If the monitoring indicates that the paging messages include a paging message intended for the device, the device may process the paging message. Furthermore, the device may indicate to the cell, when attaching to the cell, whether the device has a capability to support standalone operation within the specified frequency band. If the indication is that the device does not support such standalone operation, the cell may not issue paging messages to the device.
