Resumé: Like any mobile system, 6G is composed of RAN, CN, and transport network. The transport network includes not only the Backhaul links connecting the CN to the RAN but also links connecting Fronthaul and Midhaul. Fronthaul and Midhaul links are related to the functional splits of the RAN that appeared in 5G. Therefore, to guarantee a very low end-to-end latency in 6G, all three parts need to be optimized, i.e., RAN, transport network, and CN. For the RAN, works need to be done to reduce the slot duration further and improve the HARQ mechanisms. The reduction of latency at the CN has already been addressed in 5G, where network slicing is used. However, ensuring very low-latency at the transport network level is still challenging, particularly on the Midhaul and backhaul links. In this thesis, we will explore the usage of the Time Sensitive Networks (TSN) protocols, and specifically the asynchronous approach, to support very-low latency traffic in Midhaul and Backhaul of 6G systems.
