CTTC awarded NIST grant to study NR V2X for sub 6 GHz and mmWave bands

We are glad to announce that the CTTC has received a grant from NIST (U.S. Commerce Department’s National Institute of Standards and Technology) call 2019-NIST-MSE-1 for a collaboration, entitled “Modeling, Simulation and Performance
Evaluation of NR V2X“, to enable and accelerate New Radio (NR) Vehicular to Everything (V2X) communications, with special emphasis on Public Safety research.

The proposal is focused on conducting timely research and building new theoretical and ns-3 based models for NR V2X. The research agenda leverages the efforts of two previous and separate activities carried out within the Mobile Networks department at CTTC, both lead by Dr. Lorenza Giupponi.

  1.   A collaboration with the University of Washington and the NIST, in the area of Public Safety networks, entitled “Modelling, Simulation and Performance Evaluation for Public Safety Networks“, funded in the context of 2017-NIST-PSIAP-01 NOFO, which resulted in the release of 3GPP Release-12 D2D (Device to Device) feature for ns-3 LTE.
  2. A collaboration with InterDigital, which resulted in the first release of a new NR model  for ns-3,  compliant with 3GPP Release-15 NR.

The planned activities include re-adaptation of upper layers, and in particular RRC (Radio Resource Control), and complete redesign of  PHY and MAC layers to account for the new flexible NR frame structure, new resource allocation granularity,     novel numerology concepts, and new features introduced in NR V2X to support improved use cases,  as compared to C-V2X. In addition, research studies in the areas of mmWave NR V2X and its redesign with beamforming, as well as interface selection, will be performed.
