Hello Mr HW_Junior.
In Huawei Maximum Ratio Threshold of PDTCH in a cells we go for only 30%. And we can use this because user can use multi-slot channel when they use the data.
If we go for 30 then it comes around 1.8 that is equal to 1, so if you want to use multi-slot then go for more than 30%. And for maximum conversion we are using different parameter in Huawei.
