Dynamic sharing of 5G and the DSRC spectrum has been considered as an attainable paradigm to provide VANETs with massive system capacity, reduced latency, and lowered cost. It can meet the ever growing expectations of tailor- made vehicular services. However, due to the high mobility of vehicles and heterogeneity of 5G spectrum, how to achieve efficient dynamic spectrum sharing for better quality of vehicular communication experience is very challenging. To address this issue, this article investigates dynamic sharing of 5G spectrum for immersive experience ( IE) driven vehicular communications. We first introduce the concept of vehicular IE features and related vehicular applications. We then present the existing spectrum sharing approaches for vehicular communications and the detailed technology parameter comparisons. We propose a sharing architecture of DSRC and 5G spectrum for IE driven vehicular communications. Finally, we highlight the key technical challenges and pinpoint future research directions toward dynamic sharing of 5G spectrum for IE driven vehicular communications.
