6G subnetworks for Life-Critical Communication

Abstract
Short range low power 6th Generation (6G) wireless subnetworks can support life critical services like engine and break control in intra-vehicle scenarios, or intra-body heart-rate control. Such services may target communication cycles below 0.1 ms and a wired-like reliability, translating to a multi-GHz spectrum demand in case of dense deployments (e.g., up to 40000 subnetworks per km <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ). We foresee the possibility for 6G subnetworks to operate as an underlay system in the below 30 GHz spectrum given its advantageous propagation condition and its limited effective utilization. 6G subnetworks should be equipped with artificial intelligence (AI) capabilities for healthy mutual coexistence, as well as for coexistence with other systems active in the same bands.
