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 ...

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;

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 ...
