1. A beamforming method, adapted to a reconfiguration intelligent surface (RIS) device, comprising:
receiving a timing synchronization signal;
establishing a frame boundary synchronized with a radio signal transmission/reflection device according to the timing synchronization signal;
receiving beam control information; and
forming a reflected beam by reflecting a radio signal beam transmitted or reflected by the radio signal transmission/reflection device according to the beam control information based on the frame boundary synchronized with the radio signal transmission/reflection device.
