This article presents a converged 5G network infrastructure and an overarching architecture to jointly support operational end-user services, proposed by the EU PPP project 5G-XHaul. The 5G-XHaul adopts common fronthaul/backhaul solution, deploying wealth of wireless technologies hybrid active/passive optical transport, supporting flexible fronthaul split options. is evaluated through novel modeling. Numerical results indicate significant energy savings at expense increased service delay.
Data analytics can be seen as a powerful tool for the fifth-generation (5G) communication system to enable transformation of envisioned challenging 5G features into reality. In current architecture, some first toward this direction have been adopted by introducing new functions in core and management domains that either run on collected communication-related data or enhance already supported network with statistics collection prediction capabilities. However, possible further enhancements...
