摘要

针对6G通感一体化（ISAC）边缘网络中联邦学习（FL）在通信带宽受限、链路动态变化及设备异构条件下的通信效率问题，构建了一种面向ISAC场景的特征信息驱动压缩与聚合协同框架（FI-ISAC-FL）。不同于现有压缩方法，联邦更新压缩与聚合决策是为实现任务相关特征与系统状态之间的协同适配而联合设计。具体来说，设计Federated-AE在线训练机制对局部更新进行在线特征压缩，实现对高维更新的特征提取与高效传输，增强压缩表示对数据变化的适应能力。同时，结合ISAC场景下的信道状态与数据分布特征，构建状态感知的自适应聚合策略，改善通信受限条件下的训练稳定性与效率。仿真结果表明，在雷达目标识别任务中，所提方法在固定通信预算下能够取得较好的模型性能，在性能与资源开销之间实现更优折中，并对强感知干扰与Non-IID数据分布表现出较强的鲁棒性。

Abstract

To address the communication-efficiency problem of federated learning (FL) in 6G integrated sensing and communication (ISAC) edge networks under limited communication bandwidth

dynamic link conditions

and device heterogeneity

a feature-information-driven collaborative compression and aggregation framework

termed FI-ISAC-FL

was developed. Unlike existing compression methods

federated update compression and aggregation were jointly designed for coordinated adaptation between task-relevant features and system states. Specifically

a Federated-AE online training mechanism was introduced to compress local updates online

by which high-dimensional updates were effectively represented and efficiently transmitted

while the adaptability of compressed representations to data variations was enhanced. In addition

a state-aware adaptive aggregation strategy was developed by incorporating channel states and data-distribution characteristics in ISAC scenarios to improve training stability and efficiency under communication constraints. Simulation results show that

in a radar target recognition task

favorable model performance is achieved under a fixed communication budget

a better trade-off between performance and resource overhead is attained

and strong robustness against severe sensing interference and Non-IID data distributions is demonstrated.
