New Radio Sidelink Simulator

5G New Radio Sidelink Link-Level Simulator is developed to accelerate the study of 5G New Radio (NR) sidelink (SL). It closely follows the Third Generation Partnership Project (3GPP) Release 16 specifications on NR SL. 

This initial release supports the following SL features, but not limited to,

  • SL slots,
  • SL Bandwidth Part (BWP) and resource pool,
  • SL slot format,
  • data and control multiplexing and scrambling,
  • SL layer mapping and precoding, and
  • blind- and feedback-based Hybrid automatic repeat request (HARQ).

To facilitate simulations, It also supports additional features such as error-free and error-prone 2nd-stage Sidelink Control Information (SCI2), constant management, range conversion, and adaptive sweeping.

If you want to cite the simulator within a scientific work, please use:

In Proceedings of the International Conference on Modeling Analysis and Simulation of Wireless and Mobile Systems (MSWiM ’22), October 24–28, 2022, Montreal, QC, Canada. ACM, NewYork, NY, USA, 10 pages.


The tool can be used to simulate a point-to-point 5G NR sidelink and evaluate the tradeoffs between system architectures and parameters. It can study the below outputs/parameters, including but not limited to:

  • block error rate curves,
  • communication range,
  • HARQ settings,
  • deployment scenarios,
  • device power class,
  • numerology, and
  • error-free and error-prone SCI2.
