Re: improve Huawei Power Congestion
at first, you should determine whether you have DL or UL power congestion. Then check the physical situation of the problematic cells based on the limiting direction (UL/DL).
- Make sure the rf plan (antenna height, antenna type, direction, tilting) is correct. Fix the overshooting and overcoverage problems.
- Make sure the feeders are not crossed, no HW failure, no VSWR, no external interference, no pilot pollution
- Check if the max output power supported by equipment is set for the cell (for DL congestion)
determine the root couse of power blocking: high load? or UE distribution (most UE's at cell edge)
for high load:
- decrease PCPICH power
- consider adding a new capacity layer or sectorisation
- adjust cell selection-reselection-active set thresholds in order to shrink the coverage of the congested cell. This may lead KPI degradation in the surrounding cells.
- adjust cell selection-reselection-active set thresholds in order to expand the coverage of the surrounding cells.
- decrease SHO overhead
- activate load balancing features if exists...

Dear fekeme
Please, Do you have any specific parameter for adjusting the decrease SHO overhead ? And
