中文摘要：

3GPP LTE采用了多种新技术来提升系统的性能的同时,也增加了LTE系统无线资源管理的复杂度.主要研究了LTE系统中上行无线资源管理算法,针对上行BSR汇报机制误差带来的问题,提出一种更精确的基于happy bits补充汇报BSR的方案来改进其上行资源调度的性能.该机制利用BSR控制单元对应的MAC子头中的两个保留比特（happy bits）,通过一定的映射规则,不需要额外的开销,更加精细的反映UE上行缓存状态信息,提高了用户和无线资源调度的效率.仿真结果表明,本文所提出的改进方案比原方案在资源利用率,吞吐量和用户公平性方面都有较为理想的提升,有效地改善了系统资源利用率.

英文摘要：

LTE uses a variety of new technologies to improve system performance.However,these applications also increased the complexity of radio resource management in the LTE system.We studied the Uplink radio resource management algorithm and propose a more accurate BSR report added program based on happy bits to improve the performance of the uplink resource scheduling.The program reflect a more sophisticated cache state information of UE uplink by using the two reserved bits（happy bits） of corresponding BSR control unit of the MAC sub-header and some mapping rules,and improve the users and the efficiency of radio resource scheduling.Simulation shows that compared to the original proposal,the proposed improvement program has an ideal enhance in resource utilization,throughput and user fairness,and effectively improve the system resource utilization.
