ETSI Decentralized Congestion Control (DCC) for vehicular communication is an essential mechanism for limiting wireless channel congestion and resource allocation of ad-hoc V2X communications. Standardized channel congestion control protocols have been designed considering mostly a single message for cooperative awareness such as CAM/BSM, while future automated vehicles will exchange additional messages, including sensor data, control information, HD-maps etc. In this paper we evaluate and improve the performance of the state-machine based DCC standardized in Europe by ETSI. We highlight the channel capacity under-utilization and the communication quality degradation, and propose three design improvements to enhance its performance. Simulation based evaluation, considering multiple standardized safety messages on a single channel, proves the performance improvement due to our proposed modifications, almost doubling the reception throughput for dense V2X communication scenarios.
