A Novel Opportunistic NOMA Scheme for 5G Massive MIMO Multicast Communications

This paper concentrates on the multicast service in the next generation (5G) communications system, and develops an opportunistic massive MIMO-NOMA scheme. The proposed scheme superimposes the signal of Non-orthogonal Multiple Access (NOMA) users on the multicast signal, and employs successive interference cancellation (SIC) to separate the signal of NOMA users from the multicast signal. This scheme also applies null space based interference cancellation to eliminate the signal leakage generated by other groups. And multi-user MIMO (MU-MIMO) linear precoding is employed in the unicast group. Numerical results revealed that opportunistic massive MIMO-NOMA system significantly satisfies the requirement of high peak spectral efficiency in typical massive MIMO scenarios.
