摘要/Abstract

摘要： 在众多资源分配的调度算法中,区别实现混合业务QoS要求的调度策略研究不多。针对现有调度算法不能同时满足多用户实时和非实时业务性能需求,提出了一种保证混合业务QoS的LTE系统下行资源分配算法。新算法采用跨层设计思想下的资源块分配机制,在EXP算法的基础上引入权重因子。仿真表明新算法能够大幅度降低LTE系统用户丢包率,改善用户公平性和吞吐量性能。

Abstract: Among the numerous scheduling algorithm of resource allocation,few studies of scheduling strategies are focused on the distinction of multi-service’s QoS requirements．This paper proposed a new downlink scheduling algorithm to satisfy the Quality of Service (QoS) needs of multi-users’ real-time services and non real-times services in the Long Term Evolution (LTE),．From a cross-layer perspective,the algorithm introduced a weight factor on the basis of EXP algorithm．Simulation results show that the proposed algorithm reduces the users data drop rate and improves the system throughput considerably,while ensures the users’ fairness.
