Analysis of Outage Latency and Throughput Performance in Industrial Factory 5G TDD Deployments
摘要：
第五代（5G）新无线电支持多种网络部署。工业工厂（InF）无线自动化用例正在出现，并引起了5G新无线电标准化组织越来越多的关注。因此，在本文中，我们提出了一个服务感知的时分双工（TDD）帧选择框架的多业务部署。我们评估的性能与国家的最先进的3GPP建模假设的InF网络部署。特别地，我们考虑动态TDD模式以及优化的上行链路功率控制设置。还结合了多业务共存场景，从而引入了服务质量（QoS）感知的动态用户调度和TDD链路选择。为了评估所提出的解决方案的性能，进行了广泛的系统级仿真，其中所提出的QoS感知方案显示68%的URLLC中断延迟减少相比，QoS不知道的解决方案。最后，本文提供了有见地的结论和设计建议的TDD无线电帧的选择，上行链路功率控制设置和最佳的QoS共存的做法，以实现一个体面的URLLC中断延迟性能的国家的最先进的InF部署。
英文摘要：
The fifth generation (5G) new radio supports a diversity of network deployments. The industrial factory (InF) wireless automation use cases are emerging and drawing an increasing attention of the 5G new radio standardization groups. Therefore, in this paper, we propose a service-aware time division duplexing (TDD) frame selection framework for multi-traffic deployments. We evaluate the performance of the InF network deployments with the state-of-the-art 3GPP modeling assumptions. In particular, we consider the dynamic TDD mode along with optimized uplink power control settings. Multi-traffic coexistence scenarios are also incorporated such that quality of service (QoS) aware dynamic user scheduling and TDD link selection are introduced. Extensive system level simulations are performed in order to evaluate the performance of the proposed solutions, where the proposed QoS-aware scheme shows 68% URLLC outage latency reduction compared to the QoS-unaware solutions. Finally, the paper offers insightful conclusions and design recommendations on the TDD radio frame selection, uplink power control settings and the best QoS-coexistence practices, in order to achieve a decent URLLC outage latency performance in the state-of-the-art InF deployments.
