根据协议描述,RSRP是测量带宽内,所有承载小区专用导频子载波的功率平均值:Reference signal received power(RSRP), is defined as the linear average over the power contributions (in [W])of the resource elements that carry cell-specific reference signals within theconsidered measurement frequency bandwidth.
如果按照协议字面理解,UE只测量导频RE上的功率,并没有对目标小区导频做滤波,这样理解显然是错的,因为不滤波就无法区分服务小区和邻区RSRP,特别是在PCI mod 3对齐场景下。
