Common RRU and BBU models

Hello Experts.

Which RRU and BBU are normally used by Huawei currently?

For which Technology?

Mainly LTE + 5G NSA support.

RRU 39 series is the last I have worked on.

With highest support of 4T4R, and I believe 80 Watt.

Can you elaborate little more on watt and 4T4R?
