In this letter, a low-feedback nonorthogonal multiple access (NOMA) scheme using massive
multiple-input multiple-output (MIMO) transmission is proposed. In particular, the proposed …

A cell-free massive multiple-input multiple-output system with non-orthogonal multiple-
access (NOMA) is investigated. An achievable sum rate is derived and compared against …

We investigate the achievable rate of a hybrid cell-free (CF) massive multiple-input multiple-
output (MIMO) non-orthogonal multiple-access (NOMA) underlaid below a primary massive …

MIMO-NOMA combines multiple-input multiple-output (MIMO) and non-orthogonal multiple
access (NOMA) techniques to address heterogeneous challenges, such as massive …

This paper seeks to answer a simple but fundamental question: what role can non-
orthogonal multiple access (NOMA) play in massive multi-in multi-out (MIMO)? It is well …

To enhance the spectral efficiency of non-orthogonal multiple access (NOMA) in massive
multiple input multiple output systems, we propose a user pairing and pair scheduling …

In this paper, we consider a massive grant-free non-orthogonal multiple access (GF-NOMA)
scheme, where devices have strict latency requirements and no retransmission …

The non-regenerative massive multi-input-multi-output (MIMO) non-orthogonal multiple
access (NOMA) relay systems are introduced in this paper. The NOMA is invoked with a …

This letter considers a legacy massive multiple-input multiple-output (MIMO) network, in
which spatial beams have been preconfigured for near-field users, and proposes to use the …

In this paper, we consider the uplink and downlink precoder design for two-user power-
domain multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) …
