Next-Generation mm-Wave Small-Cell Networks: Multiple Access, Caching, and Resource Management

Abstract

Millimeter wave (mmWave) small cells have been considered as an effective technique of significantly improving the data rates of future networks. More particularly, this article investigates the potential benefits of mmWave small cell networks from the perspective of non-orthogonal multiple access (NOMA) and wireless caching. We highlight a range of innovative resource management solutions conceived for mmWave small cell networks by invoking adaptive learning. Finally, several promising future research directions of mmWave small cell networks are identified.
