无线资源管理算法对于优化LTE-Advanced系统容量和终端用户性能是非常重要的。网络算法没有实现标准化,但网络供应商和运营商可以根据需要设计和调整算法。要提供蜂窝所需的QoS,动态分组调度和链路自适应是确保高频谱效率的关键特征。通过引入第2层调度与链路自适应框架,阐述了频域分组调度原理,提出了时域和频域联合调度算法,介绍了采用MIMO的分组调度技术,评估了下行链路分组调度性能。
Radio resource management algorithms are important for optimizing LTE-Advanced system capacity and end-user performance. Network algorithms are not standardized, but network providers and operators can design and tune algorithms as needed. The QoS required to provide cellular, dynamic packet scheduling and link adaptation are key features that ensure high spectral efficiency. By introducing Layer 2 scheduling and link adaptation framework, the principle of frequency domain packet scheduling is expounded. A joint scheduling algorithm in time domain and frequency domain is proposed. The packet scheduling technology using MIMO is introduced to evaluate the performance of downlink packet scheduling.
