“…On each edge between two agents, data needs to be exchanged, and hence, a block representing the communication FG is placed between two connected agents. Since the communication block is also described by means of a FG (see [57] for an example), it can be readily placed between the FGs of two agents. It should be noted, that the specific structure of the FG depends on whether an agent is a transmitting or receiving agent.…”

Swarm exploration by multi-agent systems relies on stable inter-agent communication. However, so far both exploration and communication have been mainly considered separately despite their strong inter-dependency in such systems. In this paper, we present the first steps towards a framework that unifies both of these realms by a “tight” integration. We propose to make exploration “communication-aware” and communication “exploration-aware” by using tools of probabilistic learning and semantic communication, thus enabling the coordination of knowledge and action in multi-agent systems. We anticipate that by a “tight” integration of the communication chain, the exploration strategy will balance the inference objective of the swarm with exploration-tailored, i.e., semantic, inter-agent communication. Thus, by such a semantic communication design, communication efficiency in terms of latency, required data rate, energy, and complexity may be improved. With this in mind, the research proposed in this work addresses challenges in the development of future distributed sensing and data processing platforms—sensor networks or mobile robotic swarms consisting of multiple agents—that can collect, communicate, and process spatially distributed sensor data.

“…These waveforms allow for higher robustness against Doppler shifts and flexible time-frequency resource allocation in exchange for a higher equalisation complexity. However, in case of severe Doppler shifts, Factor Graph based equalisation for FBMC transmissions outperforms the OFDM system in terms of complexity and performance [27].…”

“…These waveforms allow for higher robustness against Doppler shifts and flexible time-frequency resource allocation in exchange for a higher equalization complexity regardless of the magnitude of the Doppler shift. However, in case of severe Doppler shifts, Factor Graph based equalization for FBMC transmissions outperforms the OFDM system in terms of complexity and performance [18]. Nevertheless, maintaining OFDM is convenient to provide compatibility with terrestrial UEs.…”

The next frontier towards truly ubiquitous connectivity is the use of Low Earth Orbit (LEO) small-satellite constellations to support 5G and Beyond-5G (B5G) networks. Besides enhanced mobile broadband (eMBB) and massive machine-type communications (mMTC), LEO constellations can support ultra-reliable communications (URC) with relaxed latency requirements of a few tens of milliseconds. Small-satellite impairments and the use of low orbits pose major challenges to the design and performance of these networks, but also open new innovation opportunities. This paper provides a comprehensive overview of the physical and logical links, along with the essential architectural and technological components that enable the full integration of LEO constellations into 5G and B5G systems. Furthermore, we characterize and compare each physical link category and explore novel techniques to maximize the achievable data rates. INDEX TERMS 5G, Beyond-5G, low Earth orbit (LEO), radio access network, small-satellite constellations.
