AbstractIn this paper, we investigate the secrecy performance of short-packet transmissions in ultra-reliable and low-latency communications (URLLC). We consider the scenario where a multi-antenna source communicates with a single-antenna legitimate receiver requiring ultra-high reliability and low latency, in the presence of a single-antenna eavesdropper. In order to safeguard URLLC, the source transmits the artificial noise (AN) signal together with the confidential signal to confuse the eavesdropper. We adopt a lower bound on the maximal secrecy rate as the secrecy performance metric for short-packet transmissions in URLLC, which takes the target decoding error probabilities at the legitimate receiver and the eavesdropper into account. Using this metric, we first derive a compact expression of the generalized secrecy outage probability (SOP). Then, we formally prove that the generalized SOP is a convex function with respect to the power allocation factor between the confidential signal and the AN signal. We further determine the optimal power allocation factor that minimizes the generalized SOP. The results presented in this work can be useful for designing new secure transmission schemes for URLLC.

The use of wireless communication systems in industrial environments is gaining international importance. The requirements, which are placed thereby on the communication systems, are manifold depending on the specific use. In the field of industrial manufacturing, however, many applications are characterized by high reliability requirements and hard real-time demands. The latter requires a time-deterministic handling of processed transmissions and therefore requires the use of Time-Sensitive Networking (TSN) solutions. In this paper, we briefly describe which functionalities characterize a wireless TSN system and which approaches have already been pursued in the literature and standardization. Subsequently, we present a concept for a toolbox that allows one to combine the required functionalities into a working solution, which can be used as a guideline for software-based implementation. Additionally, since reliability of transmissions is one of the key challenges, especially in wireless communication, to achieve a performance comparable to wired systems, we provide some further design considerations to improve.

Recently, Flying Ad-hoc Networks (FANETs), enabling ad-hoc networking between highly mobile Unmanned Aerial Vehicles (UAVs), are gaining importance in several military, commercial and civilian applications. The sensitivity of these missions requires precise and prompt data delivery. Thus, the most important communication requirements that need to be addressed while designing FANETs are of high reliability and low latency. Considering these demands, this chapter focusses on mobility models, MAC protocols and routing protocols.
