Abstract
Communication reliability is typically assessed by averaging the QoS success indicator over spatial and temporal variables. The meta distribution (MD) has recently emerged as a powerful two-level analysis framework, providing insights into system-level (outer) reliability relative to link-level (inner) thresholds. While prior studies focus on first-order spatiotemporal MD reliability, applications beyond this structure remain unexplored. This work introduces a second-order MD reliability analysis framework and applies it to spatial-spectral-temporal MD analysis for frequency-hopping THz communication. Numerical results show how inner-layer target reliabilities in temporal/spectral domains affect overall spatial MD reliability. It is also shown that adopting a non-uniform frequency-hopping pattern enhances spatial MD reliability but reduces resiliency and increases jamming risk.
