5G Network Slicing for Vehicle-to-Everything Services

The multitude of key vertical markets targeted by 5G networks calls for the support of multiple network slices on a common and programmable infrastructure. A network slice is intended as a collection of logical network functions and parameter configurations tailored to support the requirements of a particular service. In this article, we present our vision on the design of 5G network slice(s) customized for Vehicle-to-Everything (V2X) services, which involve vehicles exchanging data with each other, with the infrastructure and any communicating entity, for improved transport fluidity, safety and comfort on the road. The suggested slicing solutions involve the partition(s) of the core network and the radio access network resources, as well as configuration of the vehicular end-device functionality, to support different V2X use cases. This research article aims to elaborate on the technological options and enablers, concerns, and challenges for the succesful deployment of 5G slice(s) for the multi-tenant V2X services.
