Abstract
A method for optimizing user equipment wireless localization using K reconfigurable intelligent surfaces reflecting signal(s) transmitted between a base station and the user equipment, the method including, whatever an a priori position of the user equipment selecting at least one reconfigurable intelligent surface to activate among the K reconfigurable intelligent surfaces, determining phases of elements of the at least one reconfigurable intelligent surface, by minimizing a predetermined cost function, depending on the a priori position, and accounting for a predetermined position error bound of the user equipment, while ensuring that at most K reconfigurable intelligent surfaces are selected, ensuring that the minimum Euclidian distance between two consecutive selected reconfigurable intelligent surfaces of a predetermined configuration, is strictly higher than a predetermined value limiting interference between additional multipath components generated by the at least one reconfigurable intelligent surface.
