摘　　要：考虑到LTE-A系统对于移动台无线资源管理(RRM)测量的要求,急需一种能同时考虑测量精度和能量消耗的RRM测量方案。为了满足上述需求,提出了一种新的测量带宽选择方法,即自适应切换测量带宽方法。该方法使得移动台可以根据信道质量自行在窄带和宽带测量之间进行切换。仿真结果显示提出的方法能够达到足够的测量精度,同时还考虑了移动台的能量消耗。With regard to User Equipment （UE） Radio Resource Management （RRM） measurement re- quirement in LTE-A system, a scheme of RRM measurement with synthetically considering measurement accuracy and power consumption is necessary. To satisfy above requirement, a new measurement bandwidth decision method is proposed. By applying this scheme, the UE can trigger between narrow and wide band- width measurement according to channel quality. Results based on the performance simulation demonstrate that the proposed trigger method achieves enough measurement accuracy and lower power consumption.
