Re: RSSI ISSUE
Were the antennas replaced too ? If Yes, it is possible that this is an intermodulation in the antennas. If the antennas are the same, then you need to put the annenuator ( 30 dB) instead of the antennas and see what the noise floor will be.

Re: RSSI ISSUE
yes .antenna changed from 5x to 8x Huawei
this issue occurred for one sector, not all sectors.
Could the following factors be influential?
Tilt
Angle
Jumper

Re: RSSI ISSUE
1. User number increased or not(Pre- Post)?
2. You are using TMA? If yes check whether attenuation in huawei is added correctly.
3. Pre Post Tilt (M+E) matches or not?
4. Further you can perform Live interference check from U2000 to see if interference is in specific frequency (only on certain PRBs).

Only jumper. If it's an intermodulation, it's easy to check. Reduce the power of the PA and monitor the noise floor.
