  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.
