1. A transmitter device comprising:
a reconfigurable intelligent surface (RIS), the RIS comprising a plurality of separately activable and controllable portions; and
a processor configured to control the RIS to generate one or more modulated symbols, wherein the processor is configured to generate an amplitude of the one or more modulated symbols by activating one or more of the plurality of portions of the RIS, and the processor is configured to generate a phase of the one or more modulated symbols by controlling one or more phase shifts applied by the one or more activated portions of the RIS, and the processor is configured to receive feedback that indicates preferred portions of the RIS for transmission.
