Reconfigurable intelligent surfaces aided mmWave NOMA: joint power allocation, phase shifts, and hybrid beamforming optimization by Xiu, Yue, Zhao, Jun, Sun, Wei, Renzo, Marco Di, Gui, Guan, Zhang, Zhongpei, Wei, Ning

“…Specifically, first, the non-convex problem is transformed into three subproblems, i.e., power allocation, joint phase shifts and analog beamforming optimization, and digital beamforming design. Then, we solve the power allocation problem by keeping fixed the phase shifts of the RIS and the hybrid beamforming. …”
