On The Advances of Fronthaul and Backhaul Communication for 5G and Beyond

The next generation wireless networks (NGWNs) are envisioned to encompass a wide variety of novel concepts and paradigm shifts which could be collected under the notion called “5G and Beyond” or “Wireless 2:0”. Massive Internet protocol (IP)–based connectivity including all of the cyber–physical systems which are capable of wireless transmission and reception (a.k.a. Internet of everything (IoE)); ubiquitous and superior quality of experience (QoE); improved security; extremely–low latency; environment–friendly operation; extended coverage, capacity, and data rate with enhanced efficiency are the prominent characteristics for the NGWNs among many others. In parallel with these characteristics, horizons of the services to be provided widen in such a way that augmented reality; online gaming with extended dimensions; improved manufacturing processes; precision farming; fully autonomous transportation are some of the eminent fields in which numerous applications are believed to develop based on the envisioned capabilities of the NGWNs. It is obvious that such ambitious anticipations come at the expense of strict and very demanding technical requirements such as a high–degree of softwarization; extremely–flexible architectures; seamless operations across ultra–dense heterogeneous networks with backward compatibility; optimized network access with sub– millisecond latencies; cross–layer adaptation and harmonization; high–degree of sustainability and reliability; increased security and extended privacy.

Even though each and every requirement item listed above constitutes a standalone and a challenging research problem, ultra–dense heterogeneous networks with backward compatibility deserves a special attention among others since NGWNs are obliged to coexist with various relatively old and/or other recently emerging technologies. Considering the cost of operation including deployment, maintenance, and optimization, an efficient provisioning of fronthaul/backhaul communication systems and modules is required.

In this special session, researchers from academia and engineers from industry are invited to contribute with their solutions to challenging problems in backhaul/fronthaul networking and communications for NGWNs. It is believed that technical contributions in this field of research pave the way for “5G and Beyond” or “Wireless 2:0” by expediting the convergence of already–existing networks and recently emerging ones. Potential topics include, but are not limited to the following:
- Analysis of coexistence of multiple network types (cellular, WiFi, WiGig, etc.), associated problems and solutions;
- Investigation of presence of concurrence of different cell sizes (macro, micro, pico, and femto) within the same local region;
- Exploration of multiple competitive high–data rate physical layer technologies such as free–space optics; visible light; terahertz; hybrid radio frequency (RF) communications and so on;
- Best practices from the industrial perspective and relevant challenges for fronthaul/backhaul communications in heterogeneous networks;
- Evaluation of security and privacy issues pertaining to fronthaul/backhaul
