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?

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
