UL Payload reduction - 5G NSA

Hi Team, i have an issue with some sites where the Payload of UL was decreased, but the DL increased almost 50% after changing the BW from 5MHz to 10MHz, the other change that was done was to increase the PMAX from 20W to 30W (due HW limitations).

The UL RSSI was increased in 2-4 dBms
