Multi-TRxPs for Industrial Automation with 5G URLLC Requirements

The Fifth Generation (5G) Ultra Reliable Low Latency Communication (URLLC) is envisioned to be one of the most promising drivers for many of the emerging use cases, including industrial automation. In this study, a factory scenario with mobile robots connected via a 5G network with two indoor cells is analyzed. The aim of this study is to analyze how URLLC requirements can be met with the aid of multi-Transmission Reception Points (TRxPs), for a scenario, which is interference limited. By means of simulations, it is shown that availability and reliability can be significantly improved by using multi-TRxPs, especially when the network becomes more loaded. In fact, optimized usage of multi-TRxPs can allow the factory to support a higher capacity while still meeting URLLC requirements. The results indicate that the choice of the number of TRxPs, which simultaneously transmit to a UE, and the locations of the TRxPs around the factory, is of high importance. A poor choice could worsen interference and lower reliability. The general conclusion is that it is best to deploy many TRxPs, but have the UE receive data from only one or maximum two at a time. Additionally, the TRxPs should be distributed enough in the factory to be able to properly improve the received signal, but far enough from the TRxPs of the other cell to limit the additional interference caused

Nonlinear Evolution Equations: Analysis and Numerics

The qualitative theory of nonlinear evolution equations is an important tool for studying the dynamical behavior of systems in science and technology. A thorough understanding of the complex behavior of such systems requires detailed analytical and numerical investigations of the underlying partial differential equations
