...Although this kind of constraints have been studied both in hybrid digital/analog precoding [11], [12] and in constant-envelope precoding in massive MIMO systems [13], [14], these studies were only focused on the designs at the transmitter, which are not applicable for the joint active beamforming design of the BSs and of the passive beamforming design at the IRS....
