A method for signal optimization between a user equipment and a reconfigurable intelligence surface includes a phase optimization step having: generating at least one modified phase combination in the state that a performance index of a current phase combination is smaller than a preset performance threshold value; evaluating whether a corresponding performance index of the modified phase combination is not smaller than the preset performance threshold value or evaluating whether the performance index of the modified phase combination is larger than the corresponding performance index of the current phase combination, to determine an optimized phase combination, enabling a corresponding performance index to be not smaller than the preset performance threshold value or not smaller than the performance index of any modified phase combination in the phase optimization step; and replacing the current phase combination by the optimized phase combination to form an updated current phase combination.
