Claim 6:
7. A system, for independently managing wireless transmission by an individual spectrum access system in a radio frequency spectrum shared by a plurality of spectrum access systems, comprising:
a processor that determines an interference budget tj;
a management module, stored in memory and coupled to the processor, that:
receives the interference budget tj from the processor;
manages a move list for the spectrum access system independently of other spectrum access systems in an absence of exchange of spectrum grant information with the other spectrum access systems; and
determines 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 accordion to, σ

wherein μj is a mean of a received power of secondary users managed by the spectrum access system in the dynamic protection area, σj is a square root of a variance of the received power, and p is a protection percentile for an incumbent in the dynamic protection area; and
a determination engine, stored in memory and coupled to the processor, that:
determines 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 the other spectrum access systems; and
suspends secondary users on the move list for the spectrum access system from emitting radio frequency signals in the radio frequency spectrum shared by the plurality of spectrum access systems.
