Abstract

This paper addresses the challenges of wireless resource allocation for 5G Ultra-reliable Low-latency Communication (URLLC) broadcast/multicast services in Vehicle-to-Everything (V2X) scenarios. It proposes three key algorithms: an iterative resource allocation approach that decomposes optimization into power and spectrum subproblems, a federated learning-based multicast resource allocation scheme that protects data privacy while enabling distributed training, and a cooperative multi-agent reinforcement learning solution that treats vehicles as intelligent nodes to jointly optimize system throughput, URLLC delivery rate, and multicast performance. Path loss models, mobility patterns, and interference scenarios are analyzed for both unicast and multicast transmissions. Simulation results demonstrate that the proposed algorithms achieve superior performance in terms of throughput, reliability, and latency compared to traditional and baseline approaches.
基于fl的无线资源分配增强5G V2X URLLC广播/组播业务
本文讨论了车对万物(V2X)场景下5G超可靠低延迟通信(URLLC)广播/多播服务无线资源分配的挑战。提出了三种关键算法:将优化分解为功率子问题和频谱子问题的迭代资源分配方法,在实现分布式训练的同时保护数据隐私的基于联邦学习的组播资源分配方案,以及将车辆视为智能节点共同优化系统吞吐量、URLLC投递率和组播性能的协作多智能体强化学习解决方案。分析了单播和组播传输的路径损耗模型、移动模式和干扰情况。仿真结果表明,与传统方法和基线方法相比,所提出的算法在吞吐量、可靠性和延迟方面具有优越的性能。

期刊介绍: The Society’s Field of Interest is “Devices, equipment, techniques and systems related to broadcast technology, including the production, distribution, transmission, and propagation aspects.” In addition to this formal FOI statement, which is used to provide guidance to the Publications Committee in the selection of content, the AdCom has further resolved that “broadcast systems includes all aspects of transmission, propagation, and reception.”
