Method and procedure for communication between databases or spectrum management functions
Abstract
Methods and apparatuses are described herein for providing a victim database discovery procedure. The victim database discovery procedure may be guided by an initial list of potential victim databases that may be defined by physical properties such as the geographic or regional relationships of the areas that may be protected by each database. Exchange procedures are disclosed in which incumbent information between two databases is exchanged. Also described herein are exchanges of information between databases whereby a querying database may receive restrictions on associated operating parameters of Cognitive Radio Systems (CRSs) under their control in an area. Further, a procedure is described herein by which a database that receives a request for shared spectrum from a CRS may first forward the request to a neighboring or victim database to determine the allowable channels and then may make the actual allocation based on this information and its own incumbents.
