Abstract：Existing researchonmulti-QoSscheduling problems，due toitsreliancesolelyonimmediatereward feedback mechanisms，faces isues ofpoor scalabilityand resource wastagewhen handlingdelay-sensitivedataand mediadata withcontinuous transmision requirements inresource-constrained scenarios.To addressthis problem，this paper proposed aRB-DQN algorithm.Thisalgorithmadjustedthecurrntstate’spolicyevaluationbybacktrackingfutureinteractions，effectivelyidentifyingandresolving packetlosscausedbysuboptimalschedulingstrategies.Additionaly，itdesignedaLTTmetric，whichcomprehensivelyconsideredtheservicerequirements ofbothdelay-sensitivedataandmedia-typedata，alowing forweightadjustmentstoemphasizediferentpriorities.Extensivesimulationresultsdemonstratethattheproposedalgorithmsignificantlyreducesthe delayand jiterofdelay-sensitivedata while ensuringthe smothnessandstabilityof media-type data，outperforming other scheduling strategies.
