  The Third Generation Partnership Project (3GPP) has standardized Coverage
Enhancement (CE) for Internet-of-Things (IoT) to connect devices in challenging
radio conditions with cellular networks. CE is based on the principle of
prolonged transmission time that exploits the fact that many IoT applications
have relaxed requirements on data rate and latency, and the coverage can be
significantly boosted by repeating transmissions for such applications.
However, CE consumes a lot of radio resources and should be implemented
carefully for different applications. This paper presents an end-to-end concept
for realizing dynamic use of CE for connected vehicles in a resource efficient
way. The proposed framework has the potential of improving coverage by around
10dB for low data rate connected vehicle applications, based on the 3GPP Long
Term Evolution (LTE) standard.
