Wireless industrial radio communication systems spawn a new set of requirements with focus on high reliability and low latency. These requirements were identified in the Industry 4.0 (I4.0) initiative as well as in 5th Generation (5G) mobile communication standardization in the form of Ultra Reliable Low Latency Communication (URLLC).

Specifically Closed-Loop-Control (CLC) applications exhibit periodic deterministic communication with short packets. These applications require ultra low latency which bars the application of retransmissions to improve reliability. Also, many CLC applications are very sensitive to burst errors but can tolerate single packet loss. Therefore, we propose to shift the focus from sum-rate maximization to burst error minimization. As a first step, we perform an extensive burst error analysis of state of the art scheduling and Resource Allocation (RA) strategies. We show that any dynamic RA outperforms a static RA by a large margin.
