Abstract
A wireless communications method synchronously transmits periodically from synchronized base stations of a single frequency network a common downlink synchronization signal (IoT-PSS) that underlays broadcasted signals transmitted in licensed bands of a cellular system, and a system frame number least significant bits signal (IoT-SFN-LSB) indicating timing of transmission of a system information block signal (IoT-SIB) that contains information related to downlink and uplink transmission schedules and allocations. An IoT device receives the common downlink synchronization signal and transmits uplink data only after receiving the synchronization signal and system frame number signal.
