摘要

通过分析LTE-Advanced系统中机器类通信（MTC）设备的随机接入效率，提出一种负载反馈控制的改进方法。利用前导状态信息估计当前负载并预测下一接入时隙的负载，然后基于负载的变化调整MTC设备接入控制参数，减少了大量MTC 设备突发性接入对人与人（H2H）设备的影响，能有效降低重传次数，提升接入成功率。通过仿真分析说明所提方案有效可行，具有良好性能。

Abstract

Through analyzing the access efficiency of machine type communication（MTC）devices in LTE-Advanced system

a loading-feedback control method was proposed.The current access load was estimated and the load of next access slot were calculated using the preamble state information

and the access control parameters for MTC device were adjusted based on the load change dynamically.The good performance of the proposed solution was evaluated by computer simulations.The simulation result shows that the proposed scheme can reduce the impact of nearly simultaneous access of a large number of MTC devices on human-to-human（H2H）devices

decrease the number of retransmissions and improve the access success rate effectively.
