  • Reconfigurable intelligent surface (RIS) based beamforming and/or modulation
    Patent number: 12192043
    Abstract: Methods and apparatuses for controlling a reconfigurable intelligent surface (RIS) to generate one or more modulated symbols may be described herein. The processor may be configured to generate an amplitude of the modulated symbol(s) by activating one or more of the plurality of portions of the RIS. The processor may be configured to generate a phase of modulated symbol(s) by controlling one or more phase shifts applied by one or more activated portions of the RIS. The method may include transmitting the one or more modulated symbols using the RIS. The method may include a RIS-based joint beamforming and/or modulation scheme with low PAPR. The RIS may be divided into one or more portions for attaining various gains. The RIS may be divided into an In-phase and/or Quadrature branches. The method may include an Amplitude-phase shift keying (A-PSK) and/or Quadrature amplitude-phase shift keying (AQ-PSK) joint beamforming and/or modulation scheme(s).
