摘要
在LTE中,小区重选是空闲模式中最重要的一项任务。通过小区重选,UE端驻留到优质的小区中。UE端通过RSRP测量,获取当前服务小区和邻近小区的质量,本文的目的即为设计出RSRP测量的实现方法,并对其进行验证。对于RSRP测量的实现方法,3GPP没有给出具体的描述,因此本文将首先设计出RSRP的计算方法,然后搭建仿真链路,对RSRP测量性能进行仿真,通过仿真验证测量带宽和加性高斯白噪声对RSRP测量值的影响。
Cell reselection is an important task in LTE idle mode.Through cell reselection,UE can camp in a high-quality cell.And UE can get the information of cell quality by RSRP measurement.Because 3GPP have not described how to performed in detail,So the paper introduced a RSRP measure algorithm,and a series of RSRP measurement simulations are performed in LTE channel models.The results shows that measurement bandwidth don＇t effects the RSRP value,and the additive Gaussian white noise is hardly influences on the RSRP value.
