Query: Path Loss Models for V2V mmWave Communication: Performance Evaluation
  and Open Challenges   Recently, millimeter wave (mmWave) bands have been investigated as a means to
enhance automated driving and address the challenging data rate and latency
demands of emerging automotive applications. For the development of those
systems to operate in bands above 6 GHz, there is a need to have accurate
channel models able to predict the peculiarities of the vehicular propagation
at these bands, especially as far as Vehicle-to-Vehicle (V2V) communications
are concerned. In this paper, we validate the channel model that the 3GPP has
proposed for NR-V2X systems, which (i) supports deployment scenarios for
urban/highway propagation, and (ii) incorporates the effects of path loss,
shadowing, line of sight probability, and static/dynamic blockage attenuation.
We also exemplify the impact of several automotive-specific parameters on the
overall network performance considering realistic system-level simulation
assumptions for typical scenarios. Finally, we highlight potential
inconsistencies of the model and provide recommendations for future measurement
campaigns in vehicular environments.
