Title:

DATA TRANSMISSION METHOD, SATELLITE BASE STATION, GATEWAY STATION, AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2023/078339

Kind Code:

A1

Abstract:

The present application discloses a data transmission method, a satellite base station, a gateway station, and a storage medium, for solving the technical problem existing in the prior art of high complexity in data and signaling transmission on a feeder link between the satellite base station and the gateway station. The method comprises: a satellite base station determines an access of a gateway station which functions as a user equipment (UE) functional module; and the satellite base station configures at least one feeder data radio bearer (DRB) for the UE functional module, the feeder DRB being used as a bearer of a feeder link for transmitting signaling and data between the satellite base station and the gateway station.
