Özet

This paper investigates the outage performance of amplify-and-forward (AF) two-way relaying under half-duplex (HD) and full-duplex (FD) operation across sixth-generation (6G) candidate bands (e.g., 4.6,7.8,15, and 40 G H z), with emphasis on an outdoor roadside vehicle-to-everything (V2X) setting. Because the end-to-end signal-to-interference-plus-noise ratio (SINR) is intractable in closed form, an upper bound is employed to derive compact lower-bound outage CDFs for both HD and FD. The bounds are validated by exact end-to-end Monte Carlo simulations. Results show that FD attains a modest outage advantage over HD when residual loop-interference is sufficiently suppressed, and that increasing the carrier frequency from 4.6 to 40 GHz degrades outage performance due to stronger frequency-dependent path loss when antenna gains are fixed.
