| Outline of Final Research Achievements |
In this study, we proposed efficient multi-access techniques and full duplexing techniques for improving spectrum efficiency, and physical channel multiplexing techniques including control signals and synchronization signals for achieving low latency for 5th generation mobile communications systems based on heterogeneous networks. We also proposed ultra multi-level modulation schemes and a multiplexing scheme of pilot signals for line-of-sight (LOS) multiple-input multiple-output (MIMO) for microwave mobile backhaul. We investigated the effects of the proposed techniques by link-level simulations.
