Abstract: Spectrum and radio resources associated with a 5G radio unit (RU) of a host network are dynamically allocated amongst one or more guest networks. A provisioning plane receives inputs from a guest network operator that identifies desired times, locations and/or frequency bands for desired network coverage. The provisioning plane responsively identifies bandwidth allocations that meet the requested parameters for exclusive use by the guest network. User equipment (UE) associated with each guest network maintains time and frequency synchronization with the host network, but otherwise limits its communications to the frequency bands allocated to the guest network. By dynamically obtaining physical radio and spectrum resources from a host provider and by scaling backend network capabilities using cloud resources, guest networks for any number of different purposes can be quickly deployed or modified as desired.
