Google patents way for satellites and cell towers to share radio space

Patent drawing
Patent drawing from the official filing.

Google describes a method for satellites and ground-based cell towers to dynamically share radio frequencies when their coverage areas overlap. The system uses configuration data from the cell tower to tell satellite users how to adjust their connection during the brief period of overlap.

Why it mattersThis helps prevent signal interference as satellite internet expands, ensuring stable connections for users moving between satellite and ground-based networks.

In the filing’s own words

This disclosure provides systems, methods, and apparatuses for managing communications within a first coverage area of a non-terrestrial network (NTN) node implementing a first radio access technology (RAT) when the first coverage area temporarily overlaps with a second coverage area of a terrestrial network (TN) base station implementing a second RAT. The NTN node and the TN base station can implement dynamic spectrum sharing (DSS) to dynamically allocate spectrum between the NTN node (of the first RAT) and the TN base station (of the second RAT) based, at least in part, on configuration information received from the TN base station and on the overlap between the first and second coverage areas.

What exactly they claim (claim 1)

1. A method for wireless communication by a non-terrestrial network (NTN) node, the method comprising: operating a first radio access technology (RAT) in a first coverage area; obtaining configuration information associated with a terrestrial network (TN) base station operating a second RAT in a second coverage area that overlaps, at a time period, with the first coverage area as the NTN node moves along a pre-defined path; communicating, to a user equipment (UE), a dynamic spectrum sharing (DSS) configuration based on the configuration information and the time period when the first coverage area overlaps with the second coverage area; and transmitting, to the UE, a downlink wireless communication based on the DSS configuration.
