      1.3.8 Post‐Shannon Perspectives (Chapter 16)

      6G network will also be the opportunity to introduce innovative communication mechanisms. Chapter 16 lays out a disruptive view of 6G, addressing major innovations becoming possible by the new post‐Shannon theory. To truly achieve the potential gains of post‐Shannon communication, we have to break with the concept of a physical layer as a mere transport channel, as the needed algorithms cannot only rely on the softwarized higher layers. A new structure of the physical layer is required to integrate new communication tasks, such as message identification, secure message transmission, and CR (common randomness, i.e. correlated results of a random experiment) generation and extraction with higher layer policies that assign different logical channels for the different services. Chapter 16 provides comprehensive insights on these challenges and evolutions.

Schematic illustration of the major trends toward 6G.

      We are only at the beginning of a long journey toward 6G, which will hit the market by 2030 and provide the major communications infrastructure until 2040. The fun part is that although it will be a global race to generate new IP, ongoing globalization of our economic markets will necessitate close cooperation among researchers on different continents. We strongly believe that in the end, 6G will be the center of all future communications, connecting all people and things on this planet with infrastructures enabling flexibility and innovation while ensuring trust, reliability, and sustainability.

      The 5th generation (5G) of wireless networks was positioned to support, besides the evolution of mobile broadband, new use cases ranging from massive IoT to ultrareliable services. However, in view of future technological innovations, researchers, industrial companies, and standardization bodies have started proposing new use cases and services that, for their generality and complementarity, would not be fully supported by 5G networks and are thus good representatives of future 6G services [1]. While the literature has a larger focus on application domains for the business‐to‐consumer (B2C) sector, this chapter discusses new beyond‐5G drivers for the business‐to‐business (B2B) markets, such as automotive, manufacturing and logistics, health and government, smart transportation, banking, and financial verticals.

      This chapter also discusses commonalities and differences among these drivers and outlines the order of magnitude of key performance indicators (KPIs) and requirements to be satisfied. In particular, while 5G‐based use cases typically present trade‐offs on latency, energy consumption, development and deployment costs, computational complexity, and throughput, 6G will be developed to meet stringent network demands in a holistic fashion, in view of the foreseen economic and business context of the 2030 era. Specifically, 6G paradigms will need to support (i) continuous connectivity, thus enabling coverage expansion compared to 5G in a cost‐efficient way to simultaneously reach high capacity, lower latency, and improved reliability; (ii) zero‐energy devices, e.g. for Internet of Things (IoT) and sensing applications for devices dispersed in wide areas for which replacing batteries will not be practical; and (iii) network‐compute integration to allow better predictions while maximizing performance in terms of latencies under 1 millisecond, low jitter, and high communication resilience.

      First generations of mobile communication networks have mainly targeted the B2C market. Offers targeting the B2B market have been mostly limited to providing connectivity to enterprise employees and providing connectivity to manufactured objects. While the first one has been present since the beginning of mobile communications with resource management offers, the second one has appeared progressively with the rise of Machine‐to‐Machine (M2M) communications, e.g., for logistics and traceability purposes. However, these use cases used to be quite marginal in the mobile network operator business, which remained focused on delivering connectivity and providing communication means to the mass market.

      5G has been a first move to complement the B2C model. The B2B market has been identified from the beginning as an important driver for 5G services, especially through ultra‐reliable low latency communications (URLLC) and massive machine type communication (mMTC) features. The deployment models of 5G have also been designed to fit enterprise needs. First, 5G standards enable the provision of end‐to‐end network slices targeting specific enterprise needs, covering both radio access network and core network. Second, some industry players are going further and have deployed their own 5G private networks, fully dedicated to their specific needs.
