Abstract:
The joint power allocation （PA） and beamforming （BF） design problem is studied to maximize the energy efficiency of a two-user downlink millimeter-wave system with non-orthogonal multiple access under imperfect channel state information （CSI）. By means of block coordinate descent， convex-concave procedure， and successive convex approximate， we propose a suboptimal joint PA and BF design scheme to address this non-convex problem. Simulation results verify that the proposed joint PA and BF design scheme is more effective when compared to some existing schemes.
