Title:
CONTROL DEVICE, CODEBOOK GENERATION DEVICE, CONTROL METHOD, CODEBOOK GENERATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/188134
Kind Code:
A1
Abstract:
This control device comprises: a control pattern selection unit for selecting a control pattern for an IRS on the basis of reference values obtained from a target of the IRS and a codebook indicating the correspondence relationships between representative values identified from the reference values; and a control unit for controlling the IRS on the basis of the control pattern. The codebook is generated by clustering a plurality of samples of the reference values of the target of the IRS into a plurality of clusters, calculating the representative values in the respective clusters from the reference values clustered into the respective clusters, calculating control patterns corresponding to the representative values, and calculating the correspondence relationships between the representative values and the control patterns.
