Study on four disruptive technologies for 5G and beyond wireless communication

A vital challenge for 5G and beyond wireless communication system is to meet the ever-growing demand for high-speed data with massive connectivity with low latency. In this report, the research outcomes of four key technologies, namely cognitive radio, non-orthogonal multiple access in heterogeneous networks, wireless caching and massive MIMO are explored for 5G and beyond systems. The key ideas for each technology are described, followed by the proposed techniques. Simulation results corroborate the superiority of proposed techniques for next generation wireless communication systems.
