Downlink Hybrid Non-Orthogonal Multiple Access Energy Minimization Design for Ultra-Massive MIMO Near-Field Communications

This paper proposes a hybrid non-orthogonal multiple access (NOMA) framework for tacking the energy efficiency optimization problem of serving additional users with pre-configured beams in the near-field downlink of ultra-massive multiple-input multiple-output (MIMO) systems. This proposed approach formulates a resourc...
