Exploiting Diversity for Ultra-Reliable and Low-Latency Wireless Control

This paper introduces a wireless communication protocol for industrial control systems that uses channel quality awareness to dynamically create network-device cooperation and assist the nodes in momentary poor conditions. To point, state information is used identify with strong weak We show network are best be served single-hop transmission rate adapted their instantaneous Meanwhile, remainder of time-frequency resources serve condition using two-hop cooperative among all meet target reliability controller. formulate achievable multi-user multi-antenna diversity gain low-latency regime, propose new scheme exploiting those on-demand, favor efficiency. The proposed therefore dubbed adaptive (ANDCoop), since it able adaptively allocate while enjoying network. optimization problem associating each group dividing between two groups. Numerical solutions significant improvement spectral efficiency system compared existing schemes literature. System design incorporating strategy can thus reduce infrastructure cost future private networks.
