Abstract

In wireless networked control systems, control and communication should not be considered independently. The co-design benefits for meeting the URLLC (Ultra-Reliable Low Latency Communication) requirements have already demonstrated that it is possible to improve resource utilization while increasing information traffic through the use of PPC (Packetized Predictive Control). This consumption is further reduced when HARQ (Hybrid Automatic Repeat reQuest) is applied. In this work, both techniques are applied, whereas supporting short packets communication, to obtain an optimum number of retransmissions and predictive control commands, aiming for better energy efficiency.
