【摘要】：在多业务的正交频分多址(OFDMA)蜂窝系统中,为改善小区整体的吞吐量并提高多用户之间传输数据的公平性,提出一种基于最优调度优先级进行资源块分配的长期演进项目(LTE)下行分配方案。打破传统资源分配过程中顺序分配资源的束缚,将用户与资源块(RB)配对,优先把服务质量最好的RB资源分配给相应的用户,尽量保证用户在各自有利的信道上传输数据。仿真结果表明,该方案在不增大丢包率的前提下,有效提高了系统的吞吐量和公平性指数,对LTE下行链路是一个很好的选择。
[Abstract]:In the multiservice orthogonal frequency division multiple access (OFDMA) cellular system, in order to improve the overall throughput of the community and improve the fairness of the data transmission between multiusers, a downlink allocation scheme (LTE) is proposed for allocation of resource blocks based on the optimal scheduling priority, which breaks the sequence of resources allocated in the traditional resource allocation process. Binding, the user is paired with the resource block (RB) to prioritise the best RB resource to the corresponding user to ensure that the user transmits data on their own favorable channels. The simulation results show that the system effectively improves the system throughput and fairness index without increasing the packet loss rate, and is one of the LTE downlinks. A good choice.
