System Enablers and Best Practices for Next-Gen Cooperative Use Cases — 5GAA Report

In the connected future of transportation, there will be an ever-growing set of cooperative Use Cases that need to be enabled in a standardised fashion. As the implementation of these Day 2+ Use Cases is different from the so far existing Use Cases, new information exchanges other than the currently existing beacon message structures will be required. To determine similarities and common mechanisms for this group of Use Cases, a definition was undertaken to provide a guideline in the field of such new Use Cases.

The term Complex Interaction was selected to describe Use Cases that require an exchange of sequential information with a minimum of three consecutive exchanges. If unique protocols and messages are to be developed for each individual Use Case, the amount of technical complexity would soon become unmanageable. Thus, it is vital to have a scalable framework for these Complex Interactions that covers common technical enablers.

Since so far no general requirements, descriptions and repeated behaviours have been identified for such Complex Interactions, the work introduced here presents an evaluation and representation of requirements which have been determined and developed during the analysis.
