NOMA-Aided Multicell Downlink Massive MIMO

Novel user clustering and pilot assignment schemes are proposed for non-orthogonal multiple access (NOMA) aided multicell massive multiple-input multiple-output systems. Our proposed designs leverage the spatial covariance matrices of users, and they are applicable to both overloaded and underloaded...
