Federated Learning–Assisted Slot-Specific SB-SPS Scheduling for Distributed C-V2X Networks*
Cellular vehicle-to-everything (C-V2X) sidelink Mode 4 relies on sensing-based semi-persistent scheduling (SB-SPS) to enable distributed resource allocation without infrastructure support. However, conventional SB-SPS suffers from resource collisions and suboptimal slot reuse under high vehicle density, particularly in...
