摘　　要：对适配第五代移动通信系统-时间敏感网络(5th Generation Mobile System-Time-Sensitive Network,5G-TSN)跨网传输的调度算法进行研究。介绍比例公平算法、最大载干比算法和最早截止时间优先算法等3种5G系统常用调度算法,并对比5G常用调度算法对时间敏感业务跨网的传输适配性。针对5G-TSN跨网传输需求,基于OMNeT++构建了5G-TSN跨网传输仿真环境,验证比例公平、最大载干比和最早截止时间优先等3种算法在多业务场景下对时间敏感业务的时延保障能力和系统吞吐量性能。验证结果表明,比例公平算法能够兼顾时间敏感业务时延性能保障与系统吞吐量,是较优的5G-TSN协同传输调度算法。The scheduling algorithms with adaption for the 5G-TSN cross-network transmission are studied.Firstly,three common scheduling algorithms for the 5G systems such as proportional fairness,maximum C/I and earliest deadline first were introduced.The adaption abilities of the 5G scheduling algorithms to time sensitive services under the 5G-TSN cross-network are compared.As to the demands of cross 5G and TSN transmission,simulation environment for the 5G-TSN cross-network transmission based on OMNeT++is built to verify the performance on the latency and throughputs of the commonly used scheduling algorithms of the 5G systems such as proportional fairness,maximum C/I and earliest deadline first in multi-service scenarios.Simulation results demonstrate that the proportional fairness algorithm can guarantee both the time delay performance of time-sensitive services and the system throughputs,and it could be an optimal scheduling algorithm for the 5G-TSN cooperative transmission.
