The 3rd Generation Partnership Project (3GPP) introduced Cellular Vehicle-to-Everything (C-V2X) as a novel technology for enabling sidelink vehicular communications. While a distributed scheduling scheme (i.e., C-V2X mode-4) has been standardized by 3GPP in order to support out-of-coverage scenarios, the design of centralized infrastructure-based schemes (i.e., C-V2X mode-3) is open to implementation. In this paper, we propose two C-V2X mode-3 schemes based on bipartite graph matching (BGM), called BGM - Pow and BGM - Dist. Specifically, BGM - Pow allocates subchannels based on the minimization of the overall power perceived by the vehicles whereas BGM - Dist is based on the maximization of the subchannels reusage distance. Through simulations we show that the proposed centralized schemes outperform C-V2X mode-4 as the subchannels can be assigned more efficiently with reduced interference.
