  5G communication system can support the demanding quality-of-service (QoS)
requirements of many advanced vehicle-to-everything (V2X) use cases. However,
the safe and efficient driving, especially of automated vehicles, may be
affected by sudden changes of the provided QoS. For that reason, the prediction
of the QoS changes and the early notification of these predicted changes to the
vehicles have been recently enabled by 5G communication systems. This solution
enables the vehicles to avoid or mitigate the effect of sudden QoS changes at
the application level. This article describes how QoS prediction could be
generated by a 5G communication system and delivered to a V2X application. The
tele-operated driving use case is used as an example to analyze the feasibility
of a QoS prediction scheme. Useful recommendations for the development of a QoS
prediction solution are provided, while open research topics are identified.
