Satellite constellation license auctions

Broadband satellite constellations in non-geostationary orbits (NGSO) will share frequency bands. They will interfere with each other from time to time. How should such conflicts be resolved? FCC rules encourage constellations to coordinate their operations, treating the shared NGSO bands as something like an FCC-supervised commons. However, spectrum regulators have increasingly used auctions to assign radio operating rights (cf. cellular licenses), and largely left it to the market to solve coordination problems. Could spectrum auctions be used for NGSO operation?

Economic rivalry, interference and spectrum allocation

I’m intrigued by the questions:

• What is the relationship (if any) between rivalry and licensing regime in spectrum regulations to date? 
• And what should it be in the future? 

 I think such work could shed light on efforts to allocate and assign millimeter-wave spectrum (roughly, above 30 GHz).
