Claim 11:
12. Non-transitory computer storage media storing instructions for execution by a system of one or more processors, the system being included in a spectrum access system, and the instructions causing the one or more processors to perform operations comprising: determining, by the spectrum access system, an interference budget tj; determining, by the spectrum access system, secondary users managed by the spectrum access system in a radio frequency spectrum shared by a plurality of spectrum access systems comprising the spectrum access system and other spectrum access systems; managing, by the spectrum access system, a move list for the spectrum access system independently of the other spectrum access systems in an absence of exchange of spectrum grant information with the other spectrum access systems; and determining, by the spectrum access system, the move list for the spectrum access system from a first moment and a second moment of an aggregate interference distribution such that the spectrum access system provides grants to its secondary users in the neighborhood of a dynamic protection area of the spectrum access system according to, σ
