Millimeter-wave (mm Wave) communications had been considered widely in recent past due to its largely available bandwidth. This paper describes a detailed survey of mm Wave communications with orthogonal multiple access (OMA), non-orthogonal multiple access (NOMA) schemes, physical design and security for future communication networks. mm Wave provides super-speed connectivity, more reliability, and higher data rate and spectral efficiency. However, communications occurring at mm Wave frequencies can easily get affected by interference and path loss. Various schemes such as small cells, heterogeneous network and hybrid beamforming are used to overcome interferences and highlight the prominence of mm Wave in future communications systems.
