Hi All,
Please help by as how can i Minimize interference by using power control. Place is hilly terrain with low inter site distance. Varies from 300 mts to 700 mts with tight BCCH planning. Window size is 6 with avg period 2(UL/DL).UL/DL level increase 22 and decrease 30.UL/DL Quality increase 2 and decrease 0. Px 3 Nx 4.Please help as I am waiting for your eagar suggestion.
hi TD,
could list all your parameters related to power control, in a neat way ?
please search for other posts related to power control, you’ll find good info.
Hi Pix,
Thanks for replying.UL Power control and DL power control is enabled.

Also Preprocess value is 2. Is that any effect on it…Vendor is ZTE.Thanks.
hi,
i’m not familiar with zte algo, so i’m just gonna comment on the very basic stuff:
POC Table:
Increase/Decrease Step size:0,MsTxPwrMax:5,MsTxPwrMin:16 –> could you translate this in dBm ? 5 –> 33dBm ?? 16 –> ??? there is probably room for improvement here, so it is important we work on those.
BsTxPwrMin:10 –> how much power is it ? 10dB less than the max power ? or Tx power = 10dBm ?
Increase uplink level:22,Decrease uplink level:30 –> there is something to improve here. Try inc level = 25 and dec level = 15
Increase uplink quality:2,Decrease uplink quality:1 — try inc qual = 3, dec qual = 1
Increase downlink level:25, – ok
Decrease downlink level:35, – ok
Increase downlink quality:2, – try 3
Decrease downlink quality:1,
Px:3,Nx:4 – ok (i’m not familiar with those)regards
pixHi Pix,
MsTxPwrMin:16 is 11 dBm.
BsTxPwrMin:10 is 20 dBm.P and N value is 3 highest sample value out of 4 values.
Can You please help me ?
hi,
ok
so the previous recommendations are still valid, and on top of them you can do:
MsTxPwrMin = 5dB or less (choose the minimum value)The step size = 0 is very surprising. It should be 2dB… but this is strongly algo dependent, so maybe 0 is fine. Could you please explain this one for me ?
regards
pixHi Pix,
Thanks for your reply.
Step size 0 means 2 db.Aside to that is there any change i can do with Ho Parameter.
Rxlevmin 15 for all cells.
Uplink receive level 15.
Downlink receive level 15.Please suggest.
TD,
I gave you a list of changes to do… Have you applied them ? what’s the result ?
Hi pix,
I Will Make this changes for 5 cells. But Need to Wait for 48 Hrs. Will Join you and share the results.Thanks and will be back soon.it cause uplink handover also
