The rapid evolution of the 6G communication landscape demands innovative approaches to address its increasing complexity. Integrated sensing and communication (ISAC) emerges as a pivotal strategy, exploiting the synergy between sensing and communication to enhance the capabilities of the 6G network. This paper examines the deployment of unmanned aerial vehicles (UAVs) as dynamic relays in full-duplex millimeter-wave (mmWave) environments, a key direction for ISAC within 6G frameworks. We focus on urban communication scenarios, specifically the base station-multi-UAV-mobile ground user (BMUM) and mobile ground user-multi-UAV-mobile ground user (MMUM) configurations, where UAVs are employed to mitigate the challenges of air-to-ground and mmWave large-scale fading. Through rigorous mathematical modeling, we present analytical solutions for the outage probability across various UAV relay selection strategies in N-Rayleigh channel conditions, validated by Monte Carlo simulations. The findings not only enhance the reliability and performance of 6G networks but also advance our understanding of the critical role ISAC plays in optimizing future communication technologies.
