Abstract: Aspects of the present disclosure relate to techniques, methods, devices, systems, and non-transitory computer readable medium for generating codebooks for reconfigurable intelligent surfaces (RIS) s. For example, a RIS controller generates a codebook for a RIS by computing weights using a discrete Fourier transform (DFT) function or a fractional Fourier transform (FrFT) function, based on reference signals (RSs) transmitted by a transmitter. The weights correspond to the RIS elements or a subset of the RIS elements. In some aspects, the computation of the weights may include oversampling factors that allow for a higher resolution of the weights and improved search for an optimal precoding setting. Different sets of weights may be used for different incoming beams. The RIS controller may be trained with a pair of transmitter and a receiver to identify/generate the codebook for an optimized set of weights under specific situations.
