The Department of Communications Engineering at the University of Bremen, Germany, is excited to announce two PhD positions within the framework of the 6G TERRAIN Project. The Department of Communications Engineering has many years of expertise in the research and development of communication systems, algorithms, and signal processing methods. In addition to scientific-technical research, the department has also been conducting scientific-organizational research activities for several years, especially in the topic area of "5G for industry" and, in the future, also for 6G for the implementation of a German 6G strategy. In the position offered, these scientific-organizational research activities are to be carried out for 6G through participation in the "6G Platform" project funded by the BMBF. The 6G Platform is part of the BMBF's 6G programme, which also includes the 6GHubs (basic research) and the 6G industry projects. The 6G-Platform brings together several national research teams with the aim of networking actors from different industrial sectors, harmonising technical approaches, ensuring that societal interests are considered in technological approaches, and promoting the visibility of German research in politics and society.

Project Overview:

6G is poised to revolutionize network architecture by integrating multi-stakeholder and multi-technology infrastructures. The 6G TERRAIN Project aims to address the challenges posed by the scale and heterogeneity of future TNTN infrastructures. By adopting Integrated Communication and Sensing (ICAS), the project seeks to enable the perception of complex and dynamic TNTNs through environmental sensing. Additionally, the project will develop a novel Native AI automation architecture, leveraging emerging large language models (LLMs) to optimize task planning and execution.
