Data-Oriented Transmission Under Jamming Attack

As wireless systems move toward 6G, ensuring ultra-reliable low-latency communication (URLLC) securely is a key design challenge. Addressing the strict latency and reliability demands requires a shift in performance evaluation. The delay-outage rate (DOR) has recently emerged as a data-oriented metric that captures the probability of transmission time exceeding a threshold under ideal conditions. This work extends the data-oriented framework to include physical layer security, focusing on jamming and eavesdropping threats. We analyze how constant and random jamming affect DOR in the multi-antenna systems, highlighting the role of spatial and spectral resources in mitigation. Our analysis, supported by empirical simulations, offers new insights for designing secure, low-latency systems resilient to jamming—supporting robust ultra- or hyper-reliable low-latency communications in future 6G networks.
