A METHOD TO DETERMINE THE RISK, FOR A CBSD, OF BEING UNAUTHORIZED TO TRANSMIT ON A GIVEN CHANNEL, WHEN A DPA LOCATED IN THE VICINITY OF THIS CBSD IS ACTIVE

摘要

According to the state of the art, the Spectrum Access System (SAS) automatically adds the grant to the "move list" of each Dynamic Protection Area (DPA) channel impacted by the grant, while waiting the next Coordinated Periodic Activities among SASes (CPAS). This mechanism, although protecting correctly the DPAs from interference, implies in a sub-optimal use of the spectrum. In order to mitigate this, the present invention describes a method to determine the risk, for a CBSD, of being unauthorized to transmit on a given channel, when a DPA located in the vicinity of this CBSD is active.
