Dear Pix,

As I know :

L_RXLEV_DL_P =-85 (threshold) ==> If RXLev is/below -85, then BSC/BTS will send a PC command to increase the RXlev with step size 2 dB (MAX_POW_INC=8). From -85, -83, -81, -79. Please cmiiw.

U_RXLEV_DL_P =-75 (threshold) ==> If RXLev is/stronger than -75, then BSC/BTS will send a PC command to decrease the RXlev with step size 2 dB (MAX_POW_DEC=8). From -70, -72, -74, -76. Please cmiiw.

With your setting, then of course the RXLev will decrease (The threshold is more strict)

By the way, could it help the RXLev in Indoor? Coz, in urban city, with crowded Sites, interference in hopping channels (SFH)often happen. And many sites in my network in Urban Area still have DTX not activated (DTX_FR_INDICATOR, DTX_HR_INDICATOR = SHALL NOT USE).
I think, by enabling the DTX, it should help reduce the interference in indoor area (building).

Thanks alot Pix!

Dear Sammy,

I’m sorry, I don’t know about B9. But I think it is similar to B10.

As Pix said, if the problem in Suburban area (fewer sites), you can try to disable PC. But not in Urban. Is there interference in ur case? Hopping channel may be?
I also experienced as same as yours, then i try to disable the PC (EN_BS_PC) in suburban area, and it worked ๐Ÿ™‚

By the way, in which country is Alcatel used? Except my country of course ๐Ÿ˜€

I thought ALU only in certain country like in my country and Vietnam ๐Ÿ˜€

Br,
