HMS-SCP：面向 V2X 协同感知的多尺度语义通信 HMS-SCP: Task-Oriented Multi-Scale Semantic Communication for V2X Cooperative Perception

精读摘要

车路协同（V2X）让车辆与基础设施交换传感器数据，突破遮挡、消除盲区，对自动驾驶安全至关重要。但在密集城区，中间融合带来的带宽需求可能压垮网络容量。HMS-SCP 提出面向任务的多尺度语义通信方案，用语义通信替代原始数据传输，在带宽与精度之间寻找更好的平衡点，为自动驾驶在真实城市环境的规模化部署扫清一个关键障碍。 Cooperative perception lets vehicles and infrastructure exchange sensor data via V2X to see beyond occlusions, but in dense urban environments cumulative bandwidth demands can overwhelm the network. HMS-SCP proposes task-oriented multi-scale semantic communication, transmitting semantics rather than raw data to balance bandwidth and accuracy. It addresses a key bottleneck for deploying cooperative driving at scale.
