Sony patents method to predict radio spectrum usage with shared data

Patent drawing
Patent drawing from the official filing.

Sony describes an electronic device that helps manage radio spectrum by predicting how primary users will behave. It uses a technique called federated learning, where multiple secondary systems share data to build a prediction model without sending all raw data to a central server.

Why it mattersThis could help wireless networks use available radio frequencies more efficiently by better anticipating when primary users need the spectrum.

In the filing’s own words

The present application relates to an electronic device and method for a spectrum management apparatus. The electronic device for the spectrum management apparatus comprises a processing circuit. The processing circuit is configured to, with respect to at least one federated prediction area in a plurality of federated prediction areas constructed based on a secondary system, obtain a primary system behavior model configured for predicting the behavior of a primary system using spectrum resources by means of federated learning.

What exactly they claim (claim 1)

1. An electronic apparatus for a spectrum management device, comprising processing circuitry configured to: obtain a primary system behavior model for predicting a behavior of a primary system making use of spectrum resources, through federated learning for at least one of a plurality of federated prediction regions constructed based on secondary systems.
