NTIA Report: Incumbent Informing Capability (IIC) for Time-Based Spectrum Sharing

DiFrancisco, Michael, Drocella, Edward, Ransom, Paul, Cooper, Charles
Abstract: 

The IIC is a mechanism for more reliably informing “new entrants” in a shared spectrum band when 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-time Spectrum Coordination System (SCS).  The IIC could replace extra layers of sharing techniques such as the environmental sensing capability (ESC), which presently is required by the Federal Communications Commission (FCC) for the Citizen Broadband Radio Service (CBRS) in the 3550-3700 MHz band.
