SAS-to-SAS co-ordination for base station configuration

Abstract

In a wireless communications system, such as a 5G CBRS system, a server maintains an inter-SAS (Spectrum Allocation System) database that stores propagation files for base stations (e.g., Citizens Broadband Radio Service Devices (CBSDs)) associated with different SASs. A first SAS retrieves, from the inter-SAS database, propagation files for other SASs' CBSDs that are nearby a (e.g., new or reconfigured) CBSD associated with the first SAS and uses the retrieved propagation files to assign, to its CBSD, channel(s) that have minimal interference with the other SASs' nearby CBSDs. The first SAS retrieves information about the nearby CBSDs from an FCC database and then communicates with the other SASs about the existence of the nearby CBSDs' propagation files in the inter-SAS database. Each other SAS ensures that the propagation files for its nearby CBSDs are in the inter-SAS database.
