Practical resource scheduling in massive-cell deployment for 5G mobile communications systems

This paper proposes the first practical resource scheduling that increases system throughput in massive-cell deployment for 5G mobile communications systems. In 5G systems, the best combination of a huge number of antennas and user equipment for communications should be decided in the scheduling. The proposed scheme searches for the suitable combination without exhaustive search and accelerates calculation of system throughput for each combination. The scheme quickly obtains the combination for which the scheduling achieves higher system throughput, and thus the scheduling can be done within the required period. Simulation and experimental measurements show that the system throughput obtained is about seven times higher than for the conventional scheme. The proposed scheme enables a future practical 5G system.
