摘要

本文提出了一种考虑EXP规则、信道质量方差、实时业务和非实时业务以及最小传输速率的下行LTE系统多类业务的qos保证跨层资源分配算法。该算法的主要特点是将所有的用户和资源块分别分步分配。数值结果表明，该算法有效地保证了用户对多类业务的QoS要求。同时，主要保持较高的吞吐量和公平性性能。

QoS-guaranteed cross-layer resource allocation algorithm for multiclass services in downlink LTE system

In this paper, a QoS-guaranteed cross-layer resource allocation algorithm for multiclass services in downlink LTE system is proposed, which takes EXP rule, channel quality variance, real-time services and non-real-time services and minimum transmission rate into account. The key features of the proposed algorithm are that all the users and resource blocks will be allocated step by step respectively. Numerical results demonstrate that the proposed algorithm effectively guarantees the user QoS requirement for multiclass services. At the same time, it mainly maintains the throughput and fairness performances in a high level.
