PDCCH enhancement feature

Hi experts.

I’m trying to understand the dynamic power feature for PDCCH in Huawei and if such a feature is used, it will increase the PDCCH power with the same aggregation layer to increase the robustness

From where additional power is coming from and how exactly that feature works? any good explanation about that feature and what the motivation about using it? I mean what gain we get by using that feature?
