Mission-level URLLC under variable Rician channel conditions

The concept of mission is industrial application specific. Channel variations during the mission can lead to violations of Ultra-Reliable Low Latency Communications (URLLC). There are two options for dealing with channel variations - reconfigure at runtime, or accept a certain number of violations. In this work, the latter is explored to find the configuration of the communication system that leads to the least violations. The goal of the study is to identify the channel parameters that, when used to configure the system, will result in the least violations given a radio survey of the environment that produces a distribution of channel parameters. A polar-coded physical layer and Orthogonal Frequency Domain Multiplexing (OFDM) are used with the channels characterised based on the K-factor distributions from two different realistic industrial channels. Optimizing the system for worse channels is concluded as insightful since it leads to the least reliability violations, with negligible impact on the latency.
