Introduction
Decision topology among CMs is for management service only
Decision topology among CMs is categorized by three cases;
Autonomous
Distributed
Centralized
Different decision topology among CMs describes how the CM make decisions on the WSOs that it serves in the coexistence sets considering other CMs
Regardless of decision topology, information sharing among CMs shall be required.

Definitions on Decision Making
Centralized decision making between two CMs is performed when one CM relegates its decisions to another CM.
Distributed decision making between two CMs is performed when one CM makes its decisions in coordination with another CM.
Autonomous decision making between two CMs is performed when one CM makes its decisions independently from another CM.

Definitions on Topology (1/2)
Autonomous
When a CM applies autonomous decision making, it makes decisions on the WSOs it serves independently from other CMs.
Through information sharing among CMs, the output of decision making of one CM shall be informed to other CMs so that other CMs would take advantage of the output of the CM, and the CM vice versa.
Distributed
When a CM applies distributed decision making, it makes decisions on the WSOs it serves and the WSOs that are members of the coexistence sets in coordination with other CMs.
One CM would determine decision making after coordinating among other CMs.

Definitions on Topology (2/2)
Centralized
When a CM applies centralized decision making, it may act at either a master CM or slave CM. The master CM makes decisions on all WSOs that both the master CM serves and slave CMs serve.
Master CM selection is prerequisite for CMs participating in centeralized topology
