The book, "Information Theoretic Methods for Future Communication Systems," edited by Onur Günlü, Rafael F. Schaefer, Holger Boche and H. Vincent Poor has now been published by MDPI Press and is available in hard copy and electronically.
Work on the BMBF 6G Hub 6G-life project was an important inspiration for the book. There are also tutorials by the editors on 6G-life and information theory at the 2023 IEEE International Conference on Communications, the 2022 IEEE Global Communications Conference and the 2022 IEEE International Conference on Communications.
