Dynamic Packet Duplication for Industrial URLLC [PDF]
Sensors, 2022 The fifth-generation (5G) network is presented as one of the main options for Industry 4.0 connectivity. To comply with critical messages, 5G offers the Ultra-Reliable and Low latency Communications (URLLC) service category with a millisecond end-to-end delay and reduced probability of failure. There are several approaches to achieve these requirements;

Can Massive MIMO Support URLLC? [PDF]
2021 IEEE 93rd Vehicular Technology Conference (VTC2021-Spring), 2021 We investigate the feasibility of using Massive MIMO to support URLLC in both coherence interval based and 3GPP compliant pilot settings. We consider grant-free uplink transmission with MMSE receiver and adopt 3GPP channel models. In the coherence interval based pilot setting, by extensive system level simulations, we find that using a Massive MIMO ...

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Toward URLLC with Proactive HARQ Adaptation
2022 Joint European Conference on Networks and Communications & 6G Summit (EuCNC/6G Summit), 2022 In this work, we propose a dynamic decision maker algorithm to improve the proactive HARQ protocol for beyond 5G networks. Based on Lyapunov stochastic optimization, our adaptation control framework dynamically selects the number of proactive retransmissions for intermittent URLLC traffic scenarios under time-varying channel conditions without ...

Sliding Network Coding for URLLC [PDF]
IEEE Transactions on Wireless Communications, 2022 In this paper, we propose a network coding (NC) based approach to ultra-reliable low-latency communication (URLLC) over erasure channels. In transmitting multiple data packets, we demonstrate that the use of random NC can improve the reliability in terms of decoding error probability, while it incurs a longer decoding delay than a well-known K ...

On the Coexistence of eMBB and URLLC in Multi-Cell Massive MIMO
IEEE Open Journal of the Communications Society, 2023 The non-orthogonal coexistence between the enhanced mobile broadband (eMBB) and the ultra-reliable low-latency communication (URLLC) in the downlink of a multi-cell massive MIMO system is rigorously analyzed in this work. We provide a unified information-

Faster URLLC: Deep Learning Waveform Fingerprinting [PDF]
2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021 Ultra-reliable low-latency communication (URLLC) is becoming an important research topic since it can boost mission-critical applications to serve 5G and its beyond. Traditionally, communication latency is determined by multiple factors such as transmission distance, signal duration and signal processing complexity.
