Resource Allocation for URLLC Service in In-Band Full-Duplex-Based V2I Networks

This paper investigates the first resource management problem for vehicular-to-infrastructure (V2I) networks under in-band full-duplex (IBFD) backhauling scheme with guaranteed ultra-reliable and low-latency (URLLC) service. The considered suffers from interference caused by three node transmission in IBFD mobility of vehicular user equipments (VUEs). allocation is formulated to jointly optimize VUE association, block assignment (RA) power (PA), while satisfying reliability latency constraints at same time. a mixed integer non-linear non-convex objective function constraints. Finding globally optimal solution this type still an open problem. To develop tractable solutions, original firstly simplified using derived equivalent expression function. proposed method then decomposed it into RA PA sub-problems. In each iteration, sub-problem solved set given solution; searched determined results. sub-problems are iteratively until converging condition achieved. Theoretical analysis proves that achieves Nash-stable equilibrium local optimality respectively. Simulation results verify effectiveness performance demonstrate algorithm outperforms state-of-the-art algorithms literatures.
