“…A discussion of the feasibility, requirements, and design challenges of an OFDM based 5G radio interface suitable for missioncritical machine type communication (MTC) concluded that multiple receive antennas are critical for interference mitigation [40]. In similar spirit, coverage and capacity aspects concerning both noise-limited and interference-limited operations for MTC were considered in [41]. Various PHY and MAC layer solutions for mMTC (massive MTC) and uMTC (ultra-reliable MTC) are discussed in [42] where they conclude that higher-layer considerations ensure lean signaling by enabling longer sleep cycles and other techniques.…”

High-performance industrial automation systems rely on tens of simultaneously active sensors and actuators and have stringent communication latency and reliability requirements. Current wireless technologies like WiFi, Bluetooth, and LTE are unable to meet these requirements, forcing the use of wired communication in industrial control systems. This paper introduces a wireless communication protocol that capitalizes on multiuser diversity and cooperative communication to achieve the ultrareliability with a low-latency constraint.Our protocol is analyzed using the communication-theoretic delay-limited-capacity framework and compared to baseline schemes that primarily exploit frequency diversity. For a scenario inspired by an industrial printing application with thirty nodes in the control loop, 20B messages transmitted between pairs of nodes and a cycle time of 2 ms, an idealized protocol can achieve a cycle failure probability (probability that any packet in a cycle is not successfully delivered) lower than 10´9 with nominal SNR below 5 dB in a 20MHz wide channel.

“…The goodput of the studied wireless technologies is not considered in this manuscript due to the static broadcast-like behavior. We base our research on the assumptions adopted from the industrial works by Ericsson [66,67]. Our custom simulator utilized in this work was previously calibrated with the real-life measurements in [68].…”

Presently, smart and connected wearable systems, such as on-body sensors and head-mounted displays, as well as other small form factor but powerful personal computers are rapidly pervading all areas of our life. Motivated by the opportunities that next-generation wearable intelligence is expected to provide, the goal of this work is to build a comprehensive understanding around some of the user-centric security and trust aspects of the emerging wearable and close-to-body wireless systems operating in mass events and under heterogeneous conditions. The paper thus intends to bring the attention of the research community to this emerging paradigm and discuss the pressing security and connectivity challenges within a popular consumer context. Our selected target scenario is that of a sports match, where wearable-equipped users may receive their preferred data over various radio access protocols. We also propose an authentication framework that allows for delivery of the desired content securely within the considered ecosystem.

“…It is shown how a combination of micro-and macroscopic diversity can achieve the signal quality outage probability required for URLLC. In [5], different deployment strategies (e.g. number of cells, frequency reuse pattern) are studied to meet the coverage requirements in a factory automation scenario, while the complementary system-level simulation results are presented in [6].…”

Abstract-Ultra-reliable low-latency communications (URLLC) entail the transmission of sporadic and small packets, with low latency and very high reliability. Among many potential areas of optimization for URLLC, the problems of large delays during HARQ retransmissions, and inaccurate link adaptation as a consequence of the rapidly-varying interference conditions are studied. The former is addressed by reducing the TTI length and HARQ round-trip time, as compared to what is used in LTE; whereas including low-pass filtered interference information in the CQI report is also proved to have great potential. Extensive system-level simulations of the downlink performance show that the URLLC requirements, i.e. latencies below 1 ms and 99.999% reliability, are achievable at low load scenarios, whereas some performance degradation (1 -3 ms latency) is experienced at higher loads due to the increased queuing delay and inter-cell interference.
