摘　　要：针对未来网络中的载波聚合技术,进行资源调度算法的研究。以用户体验质量(QoE)为优化目标,提出以用户平均意见得分(MOS)的增量效用为依据,确定用户时频资源分配的优先级。通过搭建效用函数等式,设计一种基于MOS增量效用的资源调度算法,在满足用户QoS速率需求的情况下,最大化系统整体QoE。在OpenairInterface (OAI)平台下实现载波聚合功能后进行的仿真结果表明,该系统整体QoE及吞吐量有明显提升。According to the carrier aggregation technology in the future network,the resource scheduling algorithm was studied.With the quality of user experience(QoE)as the optimization goal,the priority of users’time-frequency resource allocation determined by incremental utility of user’s mean opinion score(MOS)was proposed.By constructing the utility function equation,a resource scheduling algorithm based on MOS incremental utility was designed to maximize the overall QoE of the system while meeting the QoS requirements of users.Simulation results after implementing carrier aggregation function on the OpenairInterface(OAI)platform show that the overall system QoE and throughput are obviously improved.
