Today it is already practically feasible to consider fully automatic operation of vehicles in restricted areas. The character of V2X service used in autonomous driving can be described as low latency, high reliability, high traffic and high mobility. In this paper we give a V2X design for 5G network to support autonomous driving. The design target is to achieve as low as 1ms delay between user planes of air interface, 99.999% air interface reliability through retransmissions limited in 10ms duration, at least 2000 vehicles per kilometer for low speed, 200 vehicles per kilometer for high speed, 50Mbps cell edge throughput for V2I, and 10Mbps rate for V2V. Using LTE Advanced as a baseline, we do some enhancements on network architecture, system frame structure, physical channels, and system procedure.
