US Patent 10581568 Network discovery and synchronization for NR-SS

Network discovery and synchronization for new radio (NR) shared spectrum (NR-SS) is discussed for a wireless network having a super frame configuration on a shared spectrum shared between a plurality of network operators. A base station may obtain a discovery preamble from a plurality of network entities within the wireless network, wherein each of the plurality of network entities belongs to one or more of the plurality of network operators and shares the super frame configuration. The base station detects the timing of the super frame configuration using the discovery preamble and may then synchronize the base station to the super frame configuration according to the detected timing.
