PHY-Layer Modeling and Throughput-Driven Adaptation for Batteryless V2X Networks
Zhaoyu Liu, Ruikang Li, Liu Cao +3
Passive overlay communication for batteryless devices is an important enabling capability for next-generation vehicle-to-everything (V2X) networks. However, enabling reliable passi…
Data-Driven Batteryless Channel Sounding for Wi-Fi 8-Inspired Downlink MU-MIMO
Muhan Zhang, Chuqi Zhang, Qitong Xu +4
Batteryless overlays couple passive throughput to Wi-Fi sounding overhead and channel state information (CSI) aging. This paper investigates channel sounding for ultra-high reliabi…
RIS-Aided E2E Multi-Path Uplink Transmission Optimization for 6G Time-Sensitive Services
Liu Cao, Zisheng Gong, Ziyue Xiao +3
The Access Traffic Steering, Switching, and Splitting (ATSSS) defined in the latest 3GPP Release 19 enables traffic flow over the multiple access paths to achieve the lower-latency…
Toward 6G Sidelink Reliability: MAC PRR Modeling for NR Mode 2 SPS and ns-3 Validation
Liu Cao, Zhaoyu Liu, Lyutianyang Zhang
5G New Radio (NR) Sidelink (SL) Mode 2 has enabled decentralized, infrastructure-less direct communications which is evolving to serve reliability-critical services in 6G SL. Parti…
A Lightweight Coordinate-Conditioned Diffusion Approach for 6G C-V2X Radio Environment Maps
Liu Cao, Zhaoyu Liu, Dongyu Wei +3
Transmitter vehicles that broadcast 6G Cellular Vehicle-to-Everything (C-V2X)-based messages, e.g., Basic Safety Messages (BSMs), are prone to be impacted by PHY issues due to the…
SALT-V: Lightweight Authentication for 5G V2X Broadcasting
Liu Cao, Weizheng Wang, Qipeng Xie +2
Vehicle-to-Everything (V2X) communication faces a critical authentication dilemma: traditional public-key schemes like ECDSA provide strong security but impose 2 ms verification de…
