摘　　要：LTE系统中的资源十分有限,在保持高速数据传输的同时还需要保证数据传输的有效性和可靠性,因此对资源的调度就显得尤为重要。LTE系统主要采用动态资源分配机制,而上行调度是动态资源分配的一个非常重要的部分,重点研究了LTE系统中上行调度过程的设计,并详细分析了仿真结果。The resources are very limited in the LTE system, while maintaining the high-speed data transmission it is also necessary to guarantee the validity and reliability of data transmission, therefore the scheduling of resources appears particularly important. Dynamic resource assignment mechanism is mainly used in LTE system, while the uplink scheduling of resources is a very important part of the dynamic resource assignment mechanism, the design of uplink scheduling process in the LTE system is provided, and the detail of analysis of the simulation result is given.
