摘要

在通信网络中,管理和分配可用资源是实现网络设计目标,同时保证所有用户对服务质量(QoS)满意的关键。多小区系统中的资源分配可以描述为通过在用户和空间方向之间分配传输功率来实现系统效用最大化。不同的资源调度算法也被用于处理用户之间的资源分配。因此,本研究为单小区多用户系统下行链路资源分配提供了一个优化框架。然后将该框架扩展到多单元系统。基于田口的方法,导出了资源最优配置的结构。利用omnet++模拟器进行了初步的仿真研究。测试了系统的MAC吞吐量和时延,以及VoIP业务应用的平均意见评分(MOS)三个性能指标。

Optimization of resource allocation using Taguchi's method for LTE-Advanced network
Managing and allocating available resources are vital in communication networks in order to attain a network design objective while keeping great satisfaction in quality of service (QoS) for all users. Resource allocation in multi-cell system can be described as maximizing of a system utility by allocating transmits power among users and spatial directions. Different resource scheduling algorithms also have been addressed to handle the resource allocation among users. Hence, this study provides an optimization framework for downlink resource allocation in a single cell with multi user system. The framework will then be extended for multi-cell system. The structure of optimal resource allocation is derived based on Taguchi's method. An initial simulation study has been carried out using OMNeT++ simulator. Three performance criteria are measured which are MAC throughput and delay of the system, and also the mean opinion score (MOS) for VoIP traffic application.
