mmWave V2X (Vehicle-to-Everything) communications can support enhanced V2X applications for connected and automated vehicles. The design of mmWave V2X communications is though not exempt of challenges as a result of propagation and highly dynamic vehicular networks and topologies. To address some of these challenges, the authors propose decoupling the mmWave MAC control and data planes, and utilize sub-6GHz V2X communications for the control plane of mmWave V2X. In this context, this study evaluates the feasibility of using C-V2X as mmWave control plane. In particular, the study proposes and analyzes two mmWave V2X scheduling schemes that utilize C-V2X to schedule mmWave transmissions. The proposed schemes are evaluated considering periodic and aperiodic C-V2X beacons. The conducted evaluation shows that an adequate design of the scheduling scheme can reduce the impact of aperiodic beacons, and facilitate the use of C-V2X as a control plane for mmWave V2X communications.
