本文提出了一种在5G移动的通信系统的超高密度分布式天线系统中实现更高系统吞吐量的高速无线电资源调度方案。在5G系统中，用于通信的大量天线和用户设备的最佳组合应该在调度中决定。所提出的方案可以搜索到最合适的组合。然后，它快速地获得系统吞吐量较高的组合，从而可以在所需的时间段内完成调度。仿真结果表明，该算法获得的系统吞吐量是穷举搜索的7.7倍。所提出的方案能够实现未来实用的5G系统。
This paper proposes a high-speed radio-resource scheduling scheme that achieves higher system throughput in ultra-high-density distributed antenna systems 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 can search for the most suitable combination. It then quickly obtains the combination for which the system throughput is higher, and thus the scheduling can be done within the required period. Simulation results show that the system throughput obtained is about 7.7 times higher than for exhaustive search. The proposed scheme enables a future practical 5G system.
