Vehicle-to-everything (V2X) technology can facilitate platoon driving, which can improve traffic efficiency in cooperative-intelligent transportation systems (C-ITS). In platoon driving, vehicles share their driving information with each other, including their location and speed. However, in congested traffic situations, there is a higher likelihood of packet collision, as the vehicles in the same platoon are using the same resources. This paper analyzes the communication QoS degradation factors that occur when operating the cooperative adaptive cruise control (CACC)-based platoon driving service. In order to improve the reliability characteristics of the dynamic information exchange vehicle-to-vehicle (V2V) link for the CACC-based platoon driving service, this paper proposed the proactive V2X PC5 resource allocation algorithm using the extended 1-stage SCI. This paper finally showed the improved communication QoS performance of the system in which the CACC-based platoon driving service is operated through the proposed resource allocation algorithm.
