MEC support for C-V2X System Architecture

This paper proposed an original four-layer architecture of MEC support for C-V2X system, summarizing the participants in C-V2X scenarios and the logical relationship between the participants. Three novel APIs are designed to meet the requirement of C-V2X end-to-end service under the MEC support for C-V2X system architecture. The general process of MEC support for C-V2X service under our architecture is also considered in this paper with two typical CV2X user cases as examples: HD Map and Intelligent Intersection.
