Abstract
The low-altitude economy (LAE) is rapidly advancing toward intelligence,
connectivity, and coordination, bringing new challenges in dynamic airspace
management, unmanned aerial vehicle (UAV) operation, and security management.
Existing systems remain fragmented and lack effective coordination. To bridge
these gaps, we propose UTICN (Ubiquitous and Trusted Intelligent
Cellular-native Network) for LAE, a unified cellular-native architecture that
integrates multi-domain sensing, high-precision positioning, intelligent
aircraft-to-everything communication, dynamic airspace management, and UAV
operational services. UTICN introduces key technologies such as integrated
sensing and communication (ISAC), passive and active positioning, intelligent
machine communication, swarm coordination, and control-data decoupled
management frameworks. We demonstrate UTICN's feasibility through two use
cases, i.e., a city-level LAE management platform and a multi-frequency
collaborative ISAC system. This work provides a fundamental reference for
building a unified operational foundation and airspace management architecture
for the LAE.
