摘要

5G 移动通信系统对服务质量（QoS）参数和异构网络场景下的高用户密度要求越来越高。从这个意义上讲，5G 网络有望处理广泛的应用和服务。因此，我们研究了能让实时（RT）和非实时（NRT）应用用户受益的调度算法。在具有多种流量模型的异构网络中，通过系统级仿真分析了新提出的 "感知信道和服务质量调度器"（CQAS）的性能，并将其与 "循环罗宾"（RR）、"最佳信道质量指标"（CQI）和 "感知服务质量调度器"（QAS）进行了比较，同时改变了用户数量以对网络进行压力测试。结果表明，CQAS 在总体吞吐量和延迟方面有显著提高，同时在可靠性和公平性指数方面表现良好。

A new Channel and QoS Aware Scheduler algorithm for real time and non real time traffic in 5G heterogeneous networks

5G mobile communication systems have increasing demands related to Quality of Service (QoS) parameters integrated with high user densification in heterogeneous network scenarios. In this sense, 5G networks are expected to handle a wide range of applications and services. Therefore, scheduling algorithms that can benefit users of real-time (RT) and non-real-time (NRT) applications are studied. System-level simulations are carried out to analyze the performance of a new proposed Channel and Quality of Service Aware scheduler (CQAS) and compare it to Round Robin (RR), Best Channel Quality Indicator (CQI), and QoS Aware Scheduler (QAS) in a heterogeneous network with multiple traffic models while varying the number of users to stress test the network. The results show that CQAS has significant gains in overall throughput and latency while performing well in the reliability and fairness index.
