ericsson difference rxlev

Std - 20th April 2018  (11:52 GMT)

Thats normal, because of using dtx and dl- power control
When you disable it and disable Hopping (and Antenne hopping) it will be eaqal
But thats the reason for using RXLEV sub....

Hi,
RxLev in Idle mode in most cases are higher than Dedicated mode. Mainly due to the fact that Idle Mode Measurements are taken on BCCH frequency which is transmitting Max power at all time. While in dedicated mode, Measurements are normally taken at TCH chnnels ( Operators normally Prefer TCH channels as priority for traffic than the BCCH), plus the effect of BTS power control feature that has been mentioned already.

must be power control effect.we should remember that power can increase or decrease in power control process depends on the radio environment and parameter settings.

It's normal in case of multiband cell when you get a TS in the inner zone.

May be it's necessary to adjust the input question information ( ot give us more info )...

BR,

Sorry, in my previous post instead 26 dBm difference should be 26 dB.

Rex - 20th April 2009  (23:56 GMT)

If you use DTX, RxLev_Full has a value let's say -91 dBm, RxLev_Sub greater than that let's say -68 dBm, while in Idle mode RxLev_Full=-65 dBm. So, RxLev_Full (Idle) is aprox. equal with RxLev_Sub (Dedicated) and RxLev_Full (Idle) is about 26 dBm greater than RxLev_Full (Dedicated). Of course,not allways. Whenever DTX is used, you'll have that difference.

greater then 20 db difference in idle(scanner) and dedicated is it normal ????

Rex - 20th April 2009  (14:36 GMT)

Which RxLev in dedicated mode? RxLev_Full or RxLev_Sub? If you have activated DTX then RxLev_Sub should be greater than RxLev_Full and nearly or equal with RxLev in Idle mode. I think that's normal.

I don't think if it's a good idea to disable power control. What i know it's normal for RxLev in dedicated mode to be less than that in idle mode.

Redan - 18th April 2009  (13:30 GMT)

Hi Rcdece, I didn't work on ericson equipment but I think that the difference is due to "power control" activation, so if you want to get the same value of Rx Lev in the two modes you have to disable it.
