论文摘要
第五代(5G)新广播支持各种网络部署。工业工厂(INF)无线自动化用例正在出现,并引起了5G新无线电标准化组的关注。因此,在本文中,我们提出了一个服务感知的时间分段双工(TDD)框架选择框架,用于多交通部署。我们通过最先进的3GPP建模假设评估了INF网络部署的性能。特别是,我们考虑动态TDD模式以及优化的上行链路电源控制设置。还合并了多流量共存方案,以便引入了服务质量(QoS)感知的动态用户调度和TDD链接选择。进行广泛的系统级模拟是为了评估所提出的解决方案的性能,其中提议的QoS感知方案显示,与QoS-Unaware解决方案相比,URLLC停电潜伏期减少了68%。最后,本文提供了有关TDD无线电框架选择,上行链路控制设置和最佳QoS-CoExcistence实践的有见地的结论和设计建议,以在最先进的Inf部署中实现不错的URLLC中断潜伏期。
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.
