RSRP和RSSI有什么区别么,在LTE测试过程中遇到的,谢谢

如题。
如题

RSSI是系统带宽的总功率(包括噪声)-@7I.a$R1k"e7`%d
RSRP是PDSCH信道的功率bbs.mscbsc.com:V%y6p*o"c+G/E
RSRQ=系统带宽的RB个数*RSRP/RSSImscbsc

 RSCP(接收信号码功率也就是每码片能量与噪声功率密度之比)=RSSI(手机在所在的载频上接收到的全部功率)+Ec/No 

RSRP是UE接收到的CRS上PORT0上所有R0均值。RSSI是有RS的那些数据块的平均功率!

这俩好像能看看漏配邻区的问题

LTE Reference Signal Received Power (RSRP)  

Definition
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 the considered measurement frequency bandwidth.
For RSRP determination the cell-specific reference signals R0 according TS 36.211 [3] shall be used. If the UE can reliably detect that R1 is available it may use R1 in addition to R0 to determine RSRP.
 
The reference point for the RSRP shall be the antenna connector of the UE.
 
If receiver diversity is in use by the UE, the reported value shall not be lower than the corresponding RSRP of any of the individual diversity branches.
Applicable for
RRC_IDLE intra-frequency,
RRC_IDLE inter-frequency,
RRC_CONNECTED intra-frequency,
RRC_CONNECTED inter-frequency

 
 
RSSI                      Received Signal Strength Indicator
 
RSSI在每个RAT里边的定义还有一些细小的差别,看看36214协议吧
