V2X deployments using IEEE 802.11p have already been announced, and the 3GPP has published the first Cellular V2X standard based on LTE-V. The limitations of IEEE 802.11p and LTE-V, and the increasing requirements of enhanced V2X applications, raise the question of whether existing V2X standards can provide the reliability levels required to support large scale deployments and the introduction of connected automated driving. Redundancy (two or more V2X links) can increase the reliability, but the gains can be limited if the various links are correlated. IEEE 802.11p and LTE-V utilize sensing-based scheduling schemes, and their MAC errors can hence be correlated since they both suffer packet collisions due to the hidden terminal problem. To address this limitation, this paper proposes the design of multi-link V2X communications where the operation of a link is adjusted with the information received through the other link. This approach is applied in this paper to design an IEEE 802.11p-assisted LTE-V scheduling scheme for multi-link and multi-RAT V2X communications. The proposed scheme is designed to increase the reliability of V2V communications in intersections under NLOS conditions.
