6GEM Perspective on Joint Communication and Sensing

Joint Communications and Sensing (JCS) requires innovative new technologies and solutions in both the HW and SW domains. The key factors for JCS are very high frequencies (GHz/THz) with large bandwidths, the agility of the 6G infrastructure spectrum, and the ability to process radio signals for multiple purposes. The Innovation potential in this area is huge, but technological challenges to be solved are also demanding. In the component and hardware area, frequencyagile RF components are subject of the development to support very high bandwidths with the lowest possible nonlinearity and power consumption. The common hardware and algorithmic challenge is to ensure coherent processing of signals, sensor fusion and in particular common waveform design, novel baseband solutions, JCS supporting packet structures and efficient edge-based processing. This article provides an overview of JCS from the perspective of the 6GEM project.
