论文摘要
5G新无线电规范的开发是由确定性低潜伏期用例（例如超可靠和低延迟通信（URLLC））得出的。 URLLC应用程序需要严格的无线电延迟和可靠性性能，例如，单向无线电潜伏期为1 ms，成功概率为99.999％。此外，对宽带容量蜂窝应用的同时逐步需求，例如增强的移动宽带（EMBB）用例。在单个无线电频谱上，URLLC和EMBB服务类之间的共存是一项艰巨的任务，因为实现紧密的URLLC无线电目标通常会导致容量损失。因此，对于电信运营商来说，了解满足各种URLLC要求的能力成本以充分计划相应的定价模型至关重要。因此，在这项工作中，对系统容量损失进行了全面分析，以达到不同的URLLC用例的各种要求。在提供了有关URLLC-EMBB服务质量共存的有价值的见解和系统设计建议的情况下，进行了一系列现实的系统级模拟。
The development of the 5G new radio specifications has been derived by the the deterministic low latency use cases such as the ultra-reliable and low-latency communications (URLLC). A URLLC application requires a stringent radio latency and reliability performance, e.g., one-way radio latency of 1 ms with 99.999% success probability. Furthermore, there is a concurrent progressive demand for broadband capacity cellular applications, e.g., enhanced mobile broadband (eMBB) use-cases. The coexistence among the URLLC and eMBB service classes over a single radio spectrum is a challenging task since achieving the tight URLLC radio targets typically results in a capacity loss. Hence, it is vital for telecom operators to understand the capacity cost of fulling the various URLLC requirements in order to sufficiently plan the corresponding pricing models. Hence, in this work, a comprehensive analysis of the system capacity loss is presented to achieve the various requirements of the different URLLC use-cases. An extensive set of realistic system level simulations is performed and introduced where valuable insights and system design recommendations on the URLLC-eMBB quality of service coexistence are presented.
