摘要
正交频分复用接入(OFDMA)具有传输速率高,带宽分配灵活等特点。文章提出了一种延迟公平资源调度算法。算法通过控制无线资源的分配来保证所有用户的等效延迟相等,从而使得所有用户在服务质量上保持公平。该算法不需要迭代计算,计算复杂度较低,适用于快速资源的分配应用环境。
Orthogonal Frequency Division Multiplex Access(OFDMA) is widely used for its characteristics of high data transmission rate and the flexibility of bandwidth allocation.In this paper,a delay-fair radio resources scheduling algorithm is proposed.The algorithm guarantees the equivalent delay by adjusting the resources allocation schemes.Thus this algorithm makes it possible to keep the fairness between the QoS of all users.The algorithm suits to fast resources allocation situation since its complexity is very low without iteration procedure.
