[fahmi]

Dear Huawei experts,

I tested PWR CTRL 3 algo and I got the results below,

How to explain that HO Qual propotion deteriorate while interference is getting better (Good signal and bad quality) ?

Not clear , i see you have improvement and reduced the sample of bad quality with good level.

Can you share the parameter settings?

Dear,

What's your parameter settings before & After?

[fahmi]

Yes but the number of HO due to Quality incresed also

Before it was PWR CTRL 2

Just check the averaging window sizing i think in huawei its called filtering window the same by default is set to 3 (3SACCH frames ) make it 6 your problem should be solved

Good,
What's the impact on Call Drop?

[fahmi]

Good,
What's the impact on Call Drop?

CDR is improving little bit

Dear

Can you share the formula for HO DL Quality %.
