Michael DiFrancisco(1), Edward Drocella(1), Charles Cooper(1), and Paul Ransom, Ph.D.(1)(1) National Telecommunications and Information Administration (NTIA) – Office of SpectrumManagement, Washington, DC 20230 Abstract: As the President's principal advisor on the regulation of the telecommunications industry, andpoliciesrelating to the Nation's economic and technological advancement,the NationalTelecommunications and Information Administration (NTIA), U.S. Department of Commerceprograms and policymaking focus largely on protecting federal spectrum-based capabilities whileexpanding the availability of spectrum for all users.Managing core federal spectrum programseffectively and efficiently, identifying innovative approaches to increase spectrum access andsharing opportunities, and ensuring that the Internet remains an engine for continued economicgrowth, which promotes a 21st century Internet economy and expands broadband Internet accessin America are a driving force for NTIA policy decisions. A key pillar of this policy is to increasespectrum access for all users through improved cooperation and collaboration between Federal andnon-Federal spectrum stakeholders. This paper describes an Incumbent Informing Capability (IIC)forTime-Based Sharing,an innovative way to increase opportunistic spectrum accesscollaboratively, securely, and dynamically within spectrum allocations principally used by thefederal government. The IIC is a mechanism for more reliably informing “new entrants” in a shared spectrum bandwhen incumbent federal systems are operating in close proximity and thus need to be protected.New entrant access to the spectrum would be controlled through an enhanced, near-real-timeSpectrum Coordination System (SCS). The IIC could replace extra layers of sharing techniquessuch as the environmental sensing capability (ESC), which presently is required by the FederalCommunications Commission (FCC) for the Citizen Broadband Radio Service (CBRS) in the3550-3700 MHz band. IIC has several potential benefits including support for mid-band spectrum sharing, reduceddependence on environmental sensing, more secure and reliable operations, and improvedincumbent control of real-time spectrum usage information. Mid-band spectrum (between 1 GHzand 10 GHz)1is valuable for broadband mobile wireless (e.g., 5G) communications because of itsfavorable propagation characteristics combined with potential for large individual channelbandwidth. This paper describes the concept for the IIC solution including operational needs and proposedbusiness processes. It outlines how the IIC could be employed to enable spectrum sharing in theCBRS 3550-3650 MHz band with potential for application to other bands in the future. Successfulimplementation of IIC will require interdisciplinary collaboration across institutions to applyAI/machine learning, secure distributed processing and data storage, and automated aggregateinterference analysis. We expect the capability to evolve over time toward a dynamic spectrumsharing paradigm in selected bands where “everyone informs”, building on work demonstrated inthe DARPA Spectrum Collaboration Challenge (SC2) that can more fully optimize the use ofspectrum. The work is relevant to US global leadership in 5G and beyond, inspiring innovationand further research into advanced dynamic spectrum sharing.
