IMT-2020候选技术--DECT-2020 New Radio的链路级性能评估
Link-Level Performance Evaluation of IMT-2020 Candidate Technology: DECT-2020 New Radio
摘要：
ETSI最近推出了DECT-2020新无线电（NR）作为mMTC和URLLC用例的IMT-2020候选技术。为了将DECT-2020 NR视为IMT-2020技术，ITU-R已经确定了不同的独立评估小组来评估其针对IMT-2020要求的性能。这些独立评估小组目前正在调查DECT-2020 NR。为了成功评估一项技术，一个重要的方面是充分了解底层物理层及其在不同环境中的性能。因此，在本文中，我们专注于DECT-2020 NR的物理层，并研究其链路级性能与标准的信道模型提供的ITU-R的评估。我们进行了大量的模拟，以分析DECT-2020 NR在URLLC和mMTC用例中的性能。本工作中呈现的结果对于独立评估小组和研究人员是有益的，因为这些结果可以帮助校准他们的物理层性能曲线。这些结果也可以直接用于未来DECT-2020 NR的系统级评估。
英文摘要：
The ETSI has recently introduced the DECT-2020 New Radio (NR) as an IMT-2020 candidate technology for the mMTC and URLLC use cases. To consider DECT-2020 NR as an IMT-2020 technology, the ITU-R has determined different independent evaluation groups to assess its performance against the IMT-2020 requirements. These independent evaluation groups are now in process of investigating the DECT-2020 NR. In order to successfully assess a technology, one important aspect is to fully understand the underlying physical layer and its performance in different environments. Therefore, in this paper, we focus on the physical layer of DECT-2020 NR and investigate its link-level performance with standard channel models provided by the ITU-R for evaluation. We perform extensive simulations to analyze the performance of DECT-2020 NR for both URLLC and mMTC use cases. The results presented in this work are beneficial for the independent evaluation groups and researchers as these results can help calibrating their physical layer performance curves. These results can also be used directly for future system-level evaluations of DECT-2020 NR.
