Abstract

Methods and apparatus for generating a codebook for a reconfigurable intelligent surface (RIS) having a plurality of reflective elements (RIS elements). In an example, a method includes determining relative location information regarding a transmitter and the RIS and a receiver and the RIS. Based on the relative location information, angle of arrival information is calculated for signals from the transmitter to the RIS elements, and angle of departure information is calculated for signals from the RIS elements to the receiver. Phase shift information for the RIS elements is calculated based on the angle of arrival and angle of departure information, and is used to select reflection coefficients for the RIS elements such that a transmitted signal is reflected from the RIS to the receiver as a coherent reflected beam. The reflection coefficients are stored as a codeword in a RIS codebook used to configure the RIS elements.
