Reconfigurable Intelligent Surface (RIS) enabled wireless communications with Non Orthogonal Multiple Access (NOMA) is a promising technology for the next generation mobile communications. Millimeter wave (mmWave) communication has high frequency ranges from 30 to 300 GHz and supports giga- bit per second data rates. The path loss attenuation is very high at high frequencies compared to low frequencies. In this paper, we consider a downlink mmWave MIMO-NOMA cellular system aided by RIS where the base station is mounted with multiple antennas and multiple single antenna users. RIS phase shifts and users power are optimized to maximize energy efficiency such that the rate of each user exceeds a certain threshold. The optimization problem is a non-convex problem, which can be solved using Dinkelbach’s algorithm with fractional program- ming. The maximization problem is converted to Quadratic Constraint Quadratic programming (QCQP), and the Lagrange augmented method is applied to get the optimum RIS phases. Numerical results show that all users satisfy the rate constraint under optimal power allocation.
