1. A method implemented by a system of one or more processors, the system being included in a spectrum access system and for independently managing wireless transmission by individual spectrum access systems in a radio frequency spectrum shared by a plurality of spectrum access systems, the method 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 the radio frequency spectrum shared by the 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
