Abstract: The anticipated trends in mobility, either autonomous driving or urban air mobility (UAM), require wireless services to achieve mandatory reliability and safety levels. The number of wireless systems already in-use, especially airborne, occupy regulated spectra. In order to mitigate the impact of a large number of systems mounted to airborne platforms, we propose to combine enabling techniques. These include the joint waveform design, multi-mode multi-port antennas (M3PAs), and appropriate beamforming techniques for joint communication, sensing and localization (JCSL). Our study finds that employing DFT-spread OFDM results in a more consistent radar performance compared to conventional OFDM, highlighting a novel application of this waveform design in JCSL systems. M3PAs are explored as a candidate system for performing JCSL using a single antenna radiator. It is shown how the orthogonality properties of M3PAs are beneficial for avoiding crosstalk in JCSL. We therefore review mature and actively employed techn
