研究可扩展TTI在5G网络中异构流量管理的优势
An Examination of the Benefits of Scalable TTI for Heterogeneous Traffic Management in 5G Networks
摘要：
连接设备的数量和种类的快速增长需要5G无线系统来应对非常异构的流量混合。因此，在传输过程中使用一个固定的TTI不一定是最有效的方法时，异构的业务类型需要同时serviced.This工作分析调度的好处，利用可扩展的TTI的基础上，其中的信道分配和TTI持续时间是适应不同的服务的最后期限和要求。我们制定了一个优化问题，考虑到个人的服务要求。然后，我们证明了优化问题是NP难的，并提供了一个启发式算法，它提供了一个有效的解决方案的问题。数值结果表明，我们提出的算法是能够找到接近最优的解决方案，以满足关键任务的通信服务的延迟要求，同时提供了一个良好的吞吐量性能的移动宽带服务。
英文摘要：
The rapid growth in the number and variety of connected devices requires 5G wireless systems to cope with a very heterogeneous traffic mix. As a consequence, the use of a fixed TTI during transmission is not necessarily the most efficacious method when heterogeneous traffic types need to be simultaneously serviced.This work analyzes the benefits of scheduling based on exploiting scalable TTI, where the channel assignment and the TTI duration are adapted to the deadlines and requirements of different services. We formulate an optimization problem by taking individual service requirements into consideration. We then prove that the optimization problem is NP-hard and provide a heuristic algorithm, which provides an effective solution to the problem. Numerical results show that our proposed algorithm is capable of finding near-optimal solutions to meet the latency requirements of mission critical communication services, while providing a good throughput performance for mobile broadband services.
