本文提出了一个协调的无线电资源调度器与硬件加速器的第五代移动的通信系统（5G）的用户吞吐量性能分析。为了确保5G超高密度分布式天线系统中移动的终端（MT）之间的公平性，必须在协调的无线电资源调度过程中计算天线和MT的大量可能组合的传输权重矩阵。为了加速计算，我们设计了一个调度器，在专用硬件上执行计算。系统级仿真表明，调度器与硬件加速器组成的5.3兆门获得约20 Mbps的平均用户吞吐量的第5百分位数为256 MT。因此，计算资源是获得高平均用户吞吐量和确保MT之间公平性的关键因素。
This paper presents a user throughput performance analysis of a coordinated radio-resource scheduler with a hardware accelerator for the fifth generation of mobile communications systems (5G). To ensure fairness among mobile terminals (MTs) in 5G ultra-high-density distributed antenna systems, the transmission weight matrixes for a huge number of possible combinations of antennas and MTs have to be computed in a coordinated radio-resource scheduling process. To accelerate the computation, we devised a scheduler that executes the computation on dedicated hardware. System-level simulations reveal that the scheduler with a hardware accelerator composed of 5.3 Mgates obtains around 20 Mbps at the 5th percentile of average user throughput for 256 MTs. Computational resources are hence the critical factor in obtaining high average user throughput and ensuring fairness among MTs.
