Sixty years of coherent versus non-coherent tradeoff as well as the twenty years of coherent versus non-coherent tradeoff in Multiple-Input Multiple-Output (MIMO) systems are surveyed.  ...  significant benefits in next-generation applications of mmWave and Terahertz solutions, in space-air-ground integrated networks, in full-duplex techniques and in other sophisticated channel coding assisted system  ...  More explicitly, the TDD separates the UL and DL in the time domain, which requires a guard interval during which the UL/DL switching transients subside.  ...

Finally, we summarise the open research challenges, provide design guidelines and potential research directions for the development of intelligent management techniques and backhaul solutions for the combination  ...  We summarise the mathematical tools widely exploited in solving these problems and the performance metrics used to evaluate the intelligent management algorithms.  ...  For NOMA-based small cells, power control and interference management for users in the different network tiers will be the most critical issue.  ...
