"In TDD 4T or 8T scenarios, the RSRP decreases by 3 dB after the number of CRS ports changes from 2 to 4. If the transmit power is not increased"
This is from the Huawei docs.
I think your confusion is why CRS4 eats more power? Well the reason is you have physical and logical antenna ports.
Example: if you configure your cells to 4T4R and CRS2, you will get all the 40watts on each antenna port. (this is your recommended setting by the way).
If you configure CRS4, you will add logical antenna ports, and the extra RS needs extra power (on each port).
For you usecase, I recommend 4T4R cells with CRS2. You can introduce TM7 if you have capable UEs. I would highly recommend "4-way received diversity", and IRC (both for PUCCH and PUSCH), these are all require enodeb licenses.
